Alexander Grothendieck 2 | 3 | - Talk given at CERN on January 27, 1972. 4 | - Original transcription by Jacqueline Picard from the magnetic recording[^6]. 5 | - Translated from French by Peio Borthelle from web sources[^3][^4]. 6 | 7 | I've always been bothered by the fact that during my research activities this 8 | influential name—Alexander Grothendieck—started becoming a common noun (as 9 | in "the Grothendieck construction" or "Grothendieck fibrations", two very 10 | common objects in categorical logic among other fields). As a matter of fact my 11 | first encounter with his name was not in the context of mathematics but 12 | listening to the speech transcribed below. A friend of mine—fellow student 13 | with whom I regularly talked about the social impact of the academic 14 | science—stumbled upon it shortly after Grothendieck's death in 2014 which 15 | generated a short burst of media interest and shared it with me. 16 | 17 | Talking with French and international colleagues I realized that in general, 18 | little was known about the interesting end of Grothendieck's career as a 19 | mathematician. Most commonly one would hear that "he left academia abruptly", 20 | that "he went to live alone secluded from society" or with uncomfortable 21 | amusement that "he refused any form of publication of his later works" (how 22 | childish can this be?). This depoliticization and "mad mathematician" trope is 23 | quite notable as his turnaround was very much in phase with the ecological and 24 | societal critics at the time (onward 1968 mobilizations). These ideas are still 25 | very relevant and active today, perhaps tagged as radical ecology. 26 | 27 | Recently I had these discussions again and realized that an English translation 28 | of this talk was nowhere to be found online. The following aims to correct this 29 | fact. Please send me any mistake you can find and feel free to reproduce the 30 | translation with or without attribution to me.

So always caught up in these fine ideas 47 | we tend—perhaps a little too much—to be satisfied with them and not to 48 | ask ourselves deeper questions. It's precisely in order to go a little deeper 49 | that it's useful to have speakers like Mr. Grothendieck, whom we have with us 50 | this evening, and to whom I'd like to hand over the floor immediately. 51 | 52 | ### Alexander Grothendieck 53 | 54 | I'm very pleased to have the opportunity to speak at CERN. For many people, 55 | including myself, CERN is one of the few citadels, so to speak, of a certain 56 | science, in fact a cutting-edge science: nuclear research. I've been proven 57 | wrong. It seems that at CERN—the European Organization for Nuclear 58 | Research—one doesn't do nuclear research. Be that as it may I think that in 59 | many people's minds CERN does. 60 | 61 | Nuclear research is indissolubly associated, for many people too, with military 62 | research, with A and H bombs, and also with something whose drawbacks are only 63 | just beginning to emerge: the proliferation of nuclear power plants. In fact, 64 | the concern that nuclear research has provoked since the end of the last world 65 | war has faded somewhat as the A-bomb explosion on Hiroshima and Nagasaki has 66 | receded into the past. Of course, the accumulation of destructive A- and H-type 67 | weapons kept a lot of people worried. A more recent phenomenon has been the 68 | proliferation of nuclear power plants to meet the growing energy needs of 69 | industrial society. However, it has become clear that this proliferation has a 70 | number of—to put it euphemistically—"extremely serious" drawbacks, and 71 | that it poses some very serious problems. The fact that cutting-edge research 72 | is associated with a real threat to the survival of mankind, a threat even to 73 | life itself on the planet, is not an exceptional situation, it's the rule. In 74 | the one or two years I've been wondering about this, I've come to realize that 75 | ultimately, in each of the major issues that currently threaten the survival of 76 | the human species, these issues would not arise in their current form—the 77 | threat to survival would not arise—if the state of our science were that of 78 | the year 1900, for example. I don't mean to imply that science is the sole 79 | cause of all these ills and dangers. There is of course a combination of 80 | several things, but science, the current state of scientific research, 81 | certainly plays an important role. 82 | 83 | First of all, perhaps I could say a few personal words. I'm a mathematician. 84 | I've devoted most of my life to mathematical research. As far as mathematical 85 | research is concerned, both the research I've done and that done by colleagues 86 | with whom I've come into contact, it seemed to me to be far removed from any 87 | kind of practical application. For this reason, for a long time I felt 88 | particularly disinclined to ask myself questions about the ins and outs of this 89 | scientific research, and in particular its social impact. It's only quite 90 | recently, in the last two years, that I've gradually begun to ask myself 91 | questions on this subject. In the future, I'll only do what's strictly 92 | necessary to support myself, since until proven otherwise I have no other 93 | profession than mathematician. I know I'm not the only one to have asked this 94 | question. Over the last year or two, and even over the last few months, more 95 | and more people have been asking key questions on this subject. I'm quite sure 96 | that at CERN too, many scientists and technicians are starting to ask them. In 97 | fact, I've met some of them. What's more, I and others know people at CERN, for 98 | example, who have "extremely serious" ideas about the so-called peaceful 99 | applications of nuclear energy; but who dare not express them publicly for fear 100 | of losing their position. Of course, this atmosphere is not specific to CERN. I 101 | believe it's an atmosphere that prevails in most academic or research 102 | organizations, in France, in Europe, and even, to a certain extent, in the 103 | United States, where people who take the risk of openly expressing their 104 | reservations—even on a strictly scientific level, about certain scientific 105 | developments—are still a tiny minority. 106 | 107 | So, for the past year or two, I've been asking myself questions. And not just 108 | to myself. I've also been asking them to colleagues and, particularly over the 109 | last few months, six months perhaps, I've been taking every opportunity to meet 110 | scientists, whether in public discussions like this one or in private, and 111 | raise these questions. In particular: "Why do we do scientific research?". A 112 | question that is virtually the same perhaps, in the long run at least, as the 113 | question: "Are we going to continue scientific research?". The extraordinary 114 | thing is to see how incapable my colleagues are of answering this question. In 115 | fact, for most of them, the question is simply so strange, so extraordinary, 116 | that they refuse even to contemplate it. In any case, they are extremely 117 | reluctant to give any kind of answer. When we manage to elicit an answer in 118 | public or private discussions, what we generally hear is, in order of frequency 119 | of response: "Scientific research? I do it because it gives me pleasure, 120 | because it gives me intellectual satisfaction". Sometimes people say, "I do 121 | scientific research because I have to make a living, because I get paid for 122 | it." 123 | 124 | As far as the first motivation is concerned, I can say that it was my main 125 | motivation during my life as a researcher. Indeed scientific research gave me 126 | pleasure and I didn't ask myself many questions beyond that. In fact if it gave 127 | me pleasure, it was largely because social consensus told me that it was a 128 | noble, positive activity, one worth undertaking; by the way without any detail 129 | on how it was positive, noble, etc. Obviously direct experience told me that 130 | with my colleagues we were building something, a certain edifice. There was a 131 | sense of progress that gave a certain feeling of achievement... of plenitude, 132 | and at the same time a certain fascination with the problems at hand. 133 | 134 | But all this, in the end doesn't answer the question: "What is the social 135 | purpose of scientific research?". Because, if its sole purpose were to give 136 | pleasure say to a handful of mathematicians or other scientists, society would 137 | doubtless hesitate to invest considerable funds in it—in mathematics they're 138 | not very considerable but in the other sciences they can be. Society would also 139 | be reluctant to pay tribute to this type of activity whereas it is rather 140 | silent about activities that may require just as much effort, but of a 141 | different type, such as playing marbles or similar. We can develop to the 142 | extreme certain facilities, certain technical faculties, be they intellectual, 143 | manual or other, but why is there this emphasis on scientific research? It's a 144 | question worth asking. 145 | 146 | Talking to many of my colleagues over the past year, I've come to realize that 147 | in fact this satisfaction that scientists are supposed to derive from 148 | exercising their cherished profession, is a pleasure... which is not a pleasure 149 | for everyone! I was astonished to discover that for most scientists, scientific 150 | research is felt to be a constraint, a servitude. Doing scientific research is 151 | a matter of life and death for any considered member of the scientific 152 | community. Scientific research is a prerequisite for getting a job, once you've 153 | embarked on this path without really knowing what it's all about. Once you've 154 | got your job, it's an imperative to move up the ladder. Once you've moved up 155 | the ladder, even assuming you've made it to the top, it's an imperative to be 156 | considered in the running. You're expected to produce. Scientific 157 | production—like any other kind of production in the ambient civilization—is 158 | considered an imperative in itself. The remarkable thing about all this is that 159 | in the end, the content of research becomes a second thought. It's all about 160 | producing a certain number of "papers". In extreme cases, a scientist's 161 | productivity is measured by the number of pages they publish. Under these 162 | conditions, for a large number of scientists—certainly for the overwhelming 163 | majority, with the real exception of a few who are fortunate enough to have an 164 | exceptional gift or to be in a social position and disposition that enables 165 | them to free themselves from these feelings of constraint—for most, 166 | scientific research is a real constraint that kills the pleasure one can have 167 | in carrying it out. 168 | 169 | This is something I discovered with amazement, because we don't talk about it. 170 | Between my students and myself, I thought there was a spontaneous and 171 | egalitarian relationship. In fact, it was an illusion in which I was trapped. 172 | Without even realizing it there was a real hierarchical relationship. The 173 | mathematicians who were my students or who considered themselves less well 174 | placed than me and who felt alienated in their work, would never have had the 175 | idea of talking to me about it until of my own accord, I left the scientific 176 | ghetto in which I was confined and tried to talk to people who weren't from my 177 | milieu. That milieu of esoteric scientists who did high mathematics. 178 | 179 | To illustrate this point I'd like to give a very concrete example. Two weeks 180 | ago I went on a tour of Brittany. Among other things, I had the opportunity to 181 | visit Nantes where I met friends and spoke at a Maison de Jeunes et de la 182 | Culture \[MJC, youth cultural center\] about the kind of issues we're 183 | discussing today. I was there on Monday. As my colleagues from the University 184 | of Nantes had been warned of my arrival, they had asked me in extremis to come 185 | and give a talk on mathematical subjects with them the following afternoon. As 186 | it happened, on the very day of my visit one of the Nantes mathematicians, Mr. 187 | Molinaro, committed suicide. So because of this unfortunate incident the 188 | mathematical talk that had been planned was cancelled. Instead I contacted a 189 | number of colleagues to ask if we could get together to talk a little about 190 | mathematical life within the mathematics department at the University and also 191 | to talk a little about this suicide. There was an extremely revealing session 192 | that afternoon in Nantes where everyone present—with one exception I'd 193 | say—clearly felt that this suicide was very very closely linked to the kind 194 | of things we'd been discussing the evening before at the MJC. 195 | 196 | In fact, I'll perhaps give one or two details. It so happened that Molinaro had 197 | two students working on post-graduate theses—I don't think they were state 198 | theses. These theses were not considered to be of sufficient scientific value. 199 | They were judged very harshly by Dieudonné, who is a good colleague of mine and 200 | with whom I wrote a major treatise on algebraic geometry. So I know him very 201 | well, he's a man of very sound scientific judgment, who is very demanding when 202 | it comes to the quality of scientific work. As a result, when these theses were 203 | being discussed by the Commission for inclusion on the list of candidates for 204 | higher education posts, he undermined them and their inclusion was refused. 205 | This of course was felt as a kind of personal affront by Molinaro who had 206 | already had difficulties before, and he committed suicide on these 207 | circumstances. In fact I had a mathematician friend called Terenhöfel who also 208 | committed suicide. I know a number of mathematicians—I'm talking mainly about 209 | mathematicians here, since that's the milieu I've known best—who have gone 210 | mad. 211 | 212 | I don't think that's something peculiar to mathematics. I think that the kind 213 | of atmosphere that prevails in the scientific world—whether mathematical or 214 | not—a kind of atmosphere with extremely rarefied air, and the pressure that 215 | is exerted on researchers have a lot to do with the evolution of these 216 | unfortunate cases. 217 | 218 | Concerning the pleasure we take in scientific research, I believe there can be 219 | enjoyment. But I've come to the conclusion that the enjoyment of some—the 220 | enjoyment of those in high places, the enjoyment of the brilliant—comes at 221 | the expense of genuine repression of the average scientist. 222 | 223 | Another aspect of this problem which goes beyond the limits of the scientific 224 | community as a whole is the fact that these high flights of human thought take 225 | place at the expense of the population as a whole which is dispossessed of all 226 | knowledge. In the sense that in the dominant ideology of our society the only 227 | true knowledge is scientific knowledge, which is the prerogative of a few 228 | million people on the planet, perhaps one person in a thousand. All the others 229 | are supposed to "not know" and in fact when you talk to them they have the 230 | impression that they "don't know". Those who do know are the ones up there in 231 | the high sciences: the mathematicians, the scientists, the very knowledgeable 232 | and so on. 233 | 234 | So I think there's quite a lot of critical comment to be made on the pleasure 235 | we get from science and its side effects. This pleasure is a kind of 236 | ideological justification for a certain course that human society is taking and 237 | as such I think that even the most disinterested science that is being done in 238 | the current context, and even the most remote from practical application, has 239 | an extremely negative impact. 240 | 241 | It's for this reason that personally I currently refrain as far as possible 242 | from taking part in this kind of activity. I'd like to clarify why I initially 243 | interrupted my research activity: it was because I realized that there were 244 | such urgent problems to be solved concerning the survival crisis that it seemed 245 | madness to waste forces on abstract scientific research. At the time I made 246 | this decision I was thinking of spending several years doing research, 247 | acquiring some basic knowledge of biology, with the idea of applying and 248 | developing mathematical techniques, mathematical methods, to deal with 249 | biological problems. It's an absolutely fascinating thing for me and from the 250 | moment some friends and I started a group called *Survivre* 251 | \[surviving\]—precisely to deal with questions of survival—from that moment 252 | on, overnight, the interest in disinterested scientific research completely 253 | vanished for me and I've never had a minute's regret since. 254 | 255 | Then there's the second motivation: science, scientific activity, allows us to 256 | earn a living. This is actually the main motivation for most scientists, 257 | according to the conversations I've had with many of them. There's a lot to be 258 | said for that too. In particular for the young people who are currently 259 | embarking on a career in science—those who study science under the assumption 260 | that they will find a ready-made job that will provide them with security. I 261 | think it's generally well known that this is a great illusion. By dint of 262 | producing highly qualified people we've really produced too many since the 263 | great boom in the production of young scientists—since Sputnik some fifteen 264 | years ago—and there's more and more unemployment in scientific careers. The 265 | problem is becoming increasingly acute for a growing number of young people, 266 | especially young scientists. In the USA we must produce something like 1000 or 267 | 1500 theses a year in mathematics alone and the number of job openings is about 268 | a third of that. 269 | 270 | On the other hand the fact remains that when science enables us to earn a 271 | salary and support ourselves, the links between our work and the satisfaction 272 | of our needs are practically cut and dried. The link is practically formed by 273 | the salary but our needs are not directly linked to the activity we perform. In 274 | fact—and this is the remarkable thing—when the question is asked: "What is 275 | the social purpose of science?", practically nobody is able to answer. The 276 | scientific activities we engage in don't serve to directly fulfill any of our 277 | needs, any of the needs of our loved ones, of people we may know. There's a 278 | perfect alienation between ourselves and our work. 279 | 280 | It's not a phenomenon peculiar to scientific activity; I think it's a situation 281 | concerning almost all professional activities within industrial civilization. 282 | It's one of the great failings of industrial civilization. 283 | 284 | As far as mathematics in particular is concerned, for the last few months I've 285 | been really trying to discover a way in which mathematical research—that 286 | which has been carried out over the last few centuries, I'm not necessarily 287 | talking about the most recent mathematical research, in which I was still 288 | involved at a fairly recent date—could be of use from the point of view of 289 | satisfying our needs. I've been talking to all kinds of mathematicians about 290 | this for the last three months. No one has been able to give me an answer. In 291 | audiences like this or smaller groups of colleagues nobody knows. I wouldn't 292 | say that any of this knowledge isn't somehow capable of being applied to make 293 | us happy, to allow us greater fulfillment, to satisfy certain genuine desires, 294 | but so far I haven't found it. Had I found it I would have been much happier, 295 | much more content in some respects, at least until recently. After all I'm a 296 | mathematician myself and it would have pleased me to know that my mathematical 297 | knowledge could be used for something socially positive. However in the two 298 | years I've been trying to understand a little bit about the course society is 299 | taking, the possibilities we have to act favorably on this course—in 300 | particular the possibilities we have to enable the survival of the human 301 | species and to enable life to evolve in a way that's worth living, that's worth 302 | surviving—my knowledge as a scientist hasn't served me once. 303 | 304 | The only point on which my training as a mathematician served me was not so 305 | much my training as a mathematician as such, nor my name as a mathematician, it 306 | was that since I was a well-known mathematician I had the opportunity to be 307 | invited by quite a few universities all over the world. This gave me the 308 | opportunity to speak with many colleagues, students and people from all over 309 | the world. This happened for the first time last spring when I toured Canada 310 | and the United States. In the space of three weeks I visited around twenty 311 | campuses. I benefited enormously from these contacts; my ideas and my vision of 312 | things have evolved enormously since then. But it's only incidentally that my 313 | mathematical background came in handy. In any case my mathematical knowledge 314 | really didn't help. 315 | 316 | I might add that since last spring, when I receive an invitation to give a 317 | mathematical talk somewhere and when I accept it, I make it clear that I'm only 318 | interested in it insofar as it gives me the opportunity to discuss more 319 | important problems such as the one we're talking about here. In general it also 320 | gives me the opportunity to talk with non-mathematicians, with scientists from 321 | other disciplines, and also with non-scientists. That's why I ask my fellow 322 | mathematicians to have at least one person from the department take charge of 323 | organizing such debates. This has been the case for example for all the 324 | conferences I've given in Canada and the USA. To date no one has ever once 325 | refused this proposal to organize non-technical, non-purely mathematical 326 | debates on the bangs of the mathematical invitation in the traditional sense. 327 | In fact since then I've also modified my practice a little by introducing, 328 | shall we say, preliminary comments into the mathematical presentations 329 | themselves so that there isn't too sharp a cut-off between the mathematical 330 | part of my stay and the other. 331 | 332 | So not only am I announcing the more general public debate that takes place 333 | afterwards but I'm also distancing myself from the very practice of inviting 334 | foreign speakers to perform a certain ritual—namely to give a high-profile 335 | lecture on a great esoteric subject in front of an audience of fifty or a 336 | hundred people, perhaps two or three of whom can painfully make some sense of 337 | it while the others feel genuinely humiliated because, effectively, they feel a 338 | social constraint placed on them to go. The first time I asked the question 339 | clearly was in Toulouse a few months ago, and I actually felt a kind of relief 340 | that these things were being said. For the first time since I've been doing 341 | this kind of lecture, spontaneously, without anything having been agreed in 342 | advance, after the mathematical lecture which was indeed very esoteric and 343 | which in itself was very tedious and burdensome—I had to apologize several 344 | times during the lecture because really it was quite intolerable—well 345 | immediately afterwards an extremely interesting discussion took place precisely 346 | on the theme: "What's the point of this kind of mathematics?" and "What's the 347 | point of this kind of ritual of giving lectures to people who have absolutely 348 | no interest in it?". 349 | 350 | My intention was not to create some kind of anti-science theory. I can see that 351 | I've barely scratched the surface of some of the problems associated with the 352 | question "Are we going to continue with scientific research?", even among those 353 | indicated on this flyer, a copy of which I've seen. For example about the 354 | possibilities of developing a scientific practice entirely different from 355 | current scientific practice and about a more detailed critique of that 356 | practice. 357 | 358 | Instead I spoke in fairly concrete terms about my personal experience—about 359 | what was passed on to me directly by others—for half an hour. That's probably 360 | enough; perhaps it would be preferable for other points to be dealt with in a 361 | little more depth during a general discussion. 362 | 363 | Before I finish my introductory speech I'd just like to say that I've brought 364 | back a few copies of a magazine we publish called *Survivre et Vivre*[^13] 365 | \[surviving and living\]. This is the group I mentioned at the beginning, which 366 | changed its name a few months ago. Instead of "surviving", after a rather 367 | significant and characteristic change of perspective it has become "surviving 368 | and living". In the beginning we started out with the fear of a possible end of 369 | the world where the essential imperative for us was the imperative of survival. 370 | Since then, through a parallel process for many of us and others outside the 371 | group we've come to a different conclusion. At first we were overwhelmed by the 372 | multiplicity of extremely tangled problems in such a way that it seemed 373 | impossible to touch any one of them without at the same time bringing on all 374 | the others. In the end we would have given in to a kind of despair, a black 375 | pessimism, had we not made the following change of perspective: within the 376 | usual system of reference in which we live—within the given type of 377 | civilization, let's call it western civilization or industrial 378 | civilization—there is no possible solution; the interweaving of economic, 379 | political, ideological and scientific problems is such that there are no 380 | possible outcomes. 381 | 382 | At the beginning we thought that with scientific knowledge—by making it 383 | available to enough people—we'd be able to better grasp a solution to the 384 | problems at hand. We've come back from that illusion. We now believe that the 385 | solution will not come from more scientific knowledge or more techniques but 386 | from a change in civilization. That's where the extremely important change of 387 | perspective comes in. For us the dominant civilization—industrial 388 | civilization—is doomed to disappear in a relatively short time, in perhaps 389 | ten, twenty or thirty years... one or two generations, in that order of 390 | magnitude; because the problems currently posed by this civilization are 391 | effectively insoluble problems. 392 | 393 | We now see our role in the following direction: to be ourselves an integral 394 | part of a process of transformations—of ferments of transformations from one 395 | type of civilization to another—which we can begin to develop right now. In 396 | this sense the problem of survival for us has been superseded, it has become 397 | the problem of life, of the transformation of our lives in the immediate 398 | future; so that they become ways of living and human relations that are worthy 399 | of being lived, and also, are viable in the long term and can serve as a 400 | starting point for the establishment of post-industrial civilizations, of new 401 | cultures. 402 | 403 | For subscriptions, please write to my address: 21, avenue Kennedy, 91 Massy; 404 | conditions are indicated in the journal. 405 | 406 | ### Discussion session 407 | 408 | > I'd love to know what you think makes life worth living. 409 | 410 | Actually, up until now, the activity, the life I've had, I've considered it 411 | worthy of living. I had the feeling of a certain type of self-fulfillment that 412 | satisfied me. Now, looking back, I see my past life in a very different light; 413 | in the sense that I realize that this fulfillment was at the same time a 414 | mutilation. Indeed it was an extremely intense activity, but in an excessively 415 | narrow direction. In such a way that all other possibilities are not covered. 416 | For me, there's absolutely no more doubt about it. The kind of activity I'm 417 | doing now is infinitely more satisfying and rewarding than the one I had during 418 | my twenty or twenty-five years as a mathematical researcher. This is a very 419 | personal point, as far as my own life is concerned. 420 | 421 | On the other hand, when I speak of a life worth living, I'm not just talking 422 | about my own life, it's about everyone's life. And I realize that the 423 | fulfillment I've been able to achieve in a very limited direction was at the 424 | expense of other people's possibilities for fulfillment. If some people have 425 | found themselves under such psychological pressure to the point of suicide, 426 | it's because of the prevailing consensus that a person's worth was judged, for 427 | example, by their technical virtuosity in proving theorems, i.e. to perform 428 | excessively specialized operations—when, the rest of the person was left 429 | completely in the shadows. This is something I've experienced time and again. 430 | When we're talking about a certain person and I ask, "Who is he?", I'm told, 431 | "He's a jerk." This meaning, among mathematicians, that it's a guy who either 432 | demonstrates theorems that aren't very interesting, or demonstrates theorems 433 | that are false, or doesn't demonstrate theorems at all! 434 | 435 | So I've defined rather negatively what I mean by a life worth living. I think 436 | that, for everyone, there's the possibility of fulfillment without being judged 437 | by others, by such narrow, simplistic, criteria. In fact, I think this scale of 438 | values has a direct mutilating effect on the possibilities for 439 | self-fulfillment. Well, this is an aspect, I don't pretend to answer the 440 | question raised here, which is a very vast one. But from the point of view 441 | we're taking here, based on scientific practice, it's the most immediate thing 442 | I can think of as an answer. 443 | 444 | > What are your views on the structure of scientific research in the People's 445 | > Republic of China? 446 | 447 | Until quite recently, let's say about three months ago, I was rather closed to 448 | any information that came from China because it was wrapped up in such jargon 449 | that, a priori, you felt like questioning it—you didn't want to take it 450 | seriously. Jargon, let's say, of an unbridled cult of Mao Tse Tung's 451 | personality, a sort of hagiography that accompanied it, meant that I read these 452 | publications quite often, but they fell out of my hands of discouragement: it 453 | just wouldn't do. Then, three months ago, I met the *New Alchemists*[^1] who made 454 | me realize the possibility of a scientific practice entirely different from 455 | that which currently prevails in all the sciences that are at universities and 456 | research institutes. From that moment, I took a renewed interest in what was 457 | happening in China, and I was motivated to go beyond, let's say, the frills of 458 | style, and try to get to the bottom of things. As a result, I became convinced 459 | that there are some extremely interesting things happening in China too, 460 | precisely in the direction of developing a new science. In any case, China is 461 | the only country where the myth of the expert is officially shattered. Where 462 | people are told: "Don't trust the experts. Don't wait for the government to 463 | send you competent folks to solve them for you. Solve them yourself with 464 | whatever means you can find on the spot." 465 | 466 | Whether we're university professors, workers or farmers, we're all capable of 467 | creative initiative, of inventing something. I think the most striking way in 468 | which these—let's call them watchwords—or this new movement has 469 | materialized, is in the development of Chinese medicine. Particularly since the 470 | Cultural Revolution. This is precisely an example of science getting out of the 471 | hands of a certain caste to become the science of all, and it is only by 472 | becoming everyone's science can it become science for everyone. In fact, 473 | practically anyone can become a doctor, whatever their cultural background. 474 | This vast movement of *barefoot doctors*[^11] has mobilized an impressive 475 | number of people—but I'm no good at statistics and can't say how many—who 476 | travel the countryside for all kinds of simple medical procedures that would 477 | only be admitted after years and years of medical study in a social context 478 | like ours. Whereas over there, after just a few months' preparation, you can 479 | practice certain medical activities. 480 | 481 | Particularly noteworthy is the sensational development of Chinese acupuncture, 482 | which has made it possible to cure certain ailments in previously unexpected 483 | cases, or as an adjunct to certain medical techniques. We know the role 484 | currently played by Chinese acupuncture in anesthesia. Acupuncture can also be 485 | used to cure all kinds of ailments, including commonplace ailments such as 486 | colds, but also, for example, very serious conditions such as pelvic organ 487 | prolapse in very advanced states. I recently had the translation of a Chinese 488 | newspaper article on this subject, which sheds some light on the differences 489 | between scientific practice—in particular medical practice in Western 490 | countries such as France or Switzerland—and practice in China, where an 491 | entirely new technique for healing very advanced organ prolapse was found by a 492 | young woman doctor who had very little formal education behind her, but who was 493 | highly motivated to to heal a specific case. On the other hand, she found 494 | herself in a cultural climate where it is not considered inadmissible, 495 | unthinkable, that a person with little knowledge, and practically no 496 | qualifications, could develop new techniques. She experimented with herself by 497 | needling on her own lower vertebrae, since she knew, from the little elementary 498 | things she had learnt, that there were direct nervous links between the pelvic 499 | floor and these vertebrae. By force of experimentation on herself, she finally 500 | found a point that caused her an extremely strong reaction that brought the 501 | pelvic organs up inside her belly. Then, convinced that she'd found the correct 502 | point, she performed the same operation on the patient she had in mind and the 503 | patient was cured. Since then, according to this newspaper, some fifty other 504 | cases have been treated, with forty-five cured. 505 | 506 | Here we can see the fundamental difference between this kind of scientific 507 | practice and scientific discoveries, and those prevailing in Western countries. 508 | First of all, the patient is no longer an object in the hands of the doctor; it 509 | is no longer the doctor who is the subject who knows and applies his knowledge 510 | to the sick object. Here, in scientific investigation, the doctor is 511 | simultaneously the object of experimentation, which at the same time enables 512 | him to overcome this \[...\] \[inaudible\] \[...\] of the position, 513 | intolerable for the patient, of being an object without will, without 514 | personality, in the hands of the doctor. And at the same time allows, I 515 | believe, a much more direct, much more intense understanding of what's going 516 | on. 517 | 518 | When you feel scientific research in your own flesh, when you feel for yourself 519 | the body's reactions, it's a completely different kind of knowledge than if you 520 | do something to a sick object with a few needles, or whatever, recording 521 | reactions purely quantitatively. I think there's a whole set of factors here, 522 | where the person's rational faculties are no longer separate from each other, 523 | for example where they are no longer separate from direct sensory experience, 524 | or from affective or ideological motivations, call them as you wish. 525 | 526 | So I think there's a real integration of our different cognitive faculties, our 527 | faculties of knowledge, which is really lacking in the dominant, Western 528 | scientific practice. Here, on the contrary, we do everything we can to separate 529 | the purely rational faculties and all the rest of our possibilities of 530 | knowledge. This is, among other things, one of the factors that has led to a 531 | sort of technological delirium, such, that scientists are able to be 532 | fascinate by technical problems, such as those posed by the construction of 533 | intercontinental missiles and the like, without even considering the atrocious 534 | implications of the eventual use of what they are building. 535 | 536 | > In your opinion, society should be transformed into a post-industrial society 537 | > in ten or twenty years. I'll even give you fifty years. Let me ask you the 538 | > following: suppose a fairy grants you unlimited power to persuade everyone to 539 | > do what you think should be done. What will you do without causing a great 540 | > catastrophe, say, famine, etc.? 541 | 542 | I think there's already a basic misunderstanding. I didn't say that anyone in 543 | particular—or anyone else, me, for example—should transform industrial society, 544 | just like that, over the next ten, twenty or thirty years years into another 545 | predetermined form of society. If a fairy were to invest me with discretionary 546 | powers, I'd tell her I didn't want to. Indeed, I'm quite convinced that what I 547 | could do would be nothing more than to create even more of a mery mess than 548 | there already is. In fact, I'm entirely convinced that absolutely no one is 549 | capable of, let's say, programming, of foreseeing the changes that are going to 550 | take place. I think that the complexity of planetary problems is so great that 551 | it absolutely defies mathematical or experimental analysis. We're in a 552 | situation where the methods of experimental science are practically useless. 553 | Because, after all, there's only one planet Earth, and a crisis situation like 554 | we're in right now, happens only once in the history of evolution. So we don't 555 | have an experience here that we can repeat at will to see what the consequences 556 | of this or that operation will be, so that we can then optimize our operation 557 | procedures. This is absolutely out of the question. This is a unique situation, 558 | with a complexity infinitely beyond our possibilities for analysis and detailed 559 | prediction. 560 | 561 | All we can do, I'm convinced, is for each of us, in our own sphere of activity, 562 | in our own environment, to try to be a of ferment of transformation in the 563 | direction that, intuitively, seems most appropriate, starting with human 564 | relationships with our family members, our children, our wives, our friends and 565 | also our colleagues. I'm convinced that this is a first transformation that has 566 | the advantage of being communicative, of communicating itself from one to 567 | another. 568 | 569 | Among the transformations to be carried out, there are in particular: 570 | overcoming of competitiveness between people; overcoming the attitude or desire 571 | of domination of one person over another, which in turn generates the desire of 572 | submission to an authority, two aspects of the same tendency; and, above all, 573 | the establishment of communication between people, which has become extremely 574 | poor in our civilization. Quite recently, I took stock of my own life and the 575 | human relationships I've had, and I was struck by how poor real communication 576 | was. For example, in mathematical circles, between colleagues, conversations 577 | are essentially about technical subjects connected to mathematics. I've had a 578 | number of romantic relationships in my life, as I'm sure most of you have, and, 579 | here too, I realized how much true communication, mutual understanding, was 580 | poor. I'm quite convinced that this is not a personal characteristic of mine, 581 | that I would personally be less gifted at communication than others. In 582 | fact, this is a general phenomenon in our culture, and indeed, when talking 583 | with many other people, I've made analogous observations. For myself, for 584 | example, I've made the general decision to pursue romantic relations with a 585 | woman only to the extent that it will appear to me as a vehicle of establishing 586 | deeper communication. See, this is just one particular example of a way 587 | in which each of us can immediately transform the way we approach others. 588 | Similarly, I can tell you that my relationship with my children has changed, in 589 | the sense that I realized that, on many occasions, I had been exercising a 590 | rather arbitrary authority over them, let's say, on things which, in good 591 | conscience, were their own responsibility. So these are things that can be 592 | changed. 593 | 594 | At first glance, one might wonder how this type of change is related to, say, 595 | the global problems of survival. I'm convinced of it, but I can't prove it, 596 | because nothing important can be proved; one can only feel it, guess it. But I 597 | am convinced that these changes in human relations will be a determining 598 | factor, perhaps the most important, in the changes we're going to see from one 599 | mode of civilization to another. Once again, it has become quite clear to me 600 | that these changes will not come about by virtue of technical innovation or 601 | structural changes. The truly profound change that is going to take place is a 602 | change in human mentalities and human relations. 603 | 604 | > I'd like to come back to scientific research. Actually, you're talking about 605 | > deviations in scientific research.

What purpose would you give to another scientific 610 | > practice? 611 | 612 | When you say inherent to science: inherent to which science? I think it's 613 | inherent to science as defined by the practice of recent centuries, as it has 614 | developed since the beginning of the exact sciences. I think it's inherent in 615 | the very method of these sciences. Among the distinctive features of this 616 | scientific practice, the first is the strict separation of our rational 617 | faculties from other modes of knowledge. Hence an instinctive distrust of all 618 | that is, let's say, emotivity, of all philosophical or religious knowledge, of 619 | all ethical considerations, anything that is felt, sensory, direct. In this 620 | sense, we have more confidence in the indications of a needle on a dial, than 621 | in what we feel immediately, directly. 622 | 623 | The following example illustrates this mistrust of immediate experience; I 624 | could cite many others, but this one is particularly striking to me. It is the 625 | case of parents that go to consult a doctor with their child, saying: "We're 626 | very unhappy, our child is becoming more and more impossible in class: he's a 627 | kleptomaniac, he fights with everyone. At home, he sulks for days on end, wets 628 | the bed, etc." And they ask the question, "Is our child sick?" So the 629 | specialist, the person who knows, is asked to pronounce a ritual formula: "your 630 | child ill" or "your child is well". In the case of "your child is ill", we 631 | expect the specialist to prescribe a drug, a method of treatment, something 632 | that will make him return to the other state, the "your child is well" case, 633 | and that's that. But if, by any chance he says: "your child is well", the 634 | parents, a little comforted, will go home and feel that there's no real 635 | problem. This, I believe, is one way of illustrating this state of mind in 636 | science, of wanting to disregard experience and state everything in terms of 637 | purely rational standards that are expressed and embodied by specialists. 638 | 639 | This brings us to the second point, the second flaw which is inherent in the 640 | scientific method. It's the analytical attitude which, of course—as I'm well 641 | aware—was necessary for the development of this type of knowledge. The 642 | practice of dividing every piece of reality, every problem, into simple 643 | components to better to solve them. And this tendency to specialization, as we 644 | know, has become increasingly important. Each of us only grasps a tiny piece of 645 | reality. As a result, each of us is perfectly powerless to grasp, to understand 646 | and to take action in any of the important issues of ones life, the life of the 647 | community or the life of the world. Because any important question has an 648 | infinite number of different aspects, its division into small slices of 649 | specialization is perfectly arbitrary, and what a single specialist can't do, a 650 | symposium of a hundred specialists from different specialities will not be able 651 | to do either. 652 | 653 | In the end, through its own internal logic, through the evolution of the 654 | analytical method, we've reached a point where, I believe, independently of the 655 | ecological crisis, there is a crisis of knowledge. In this sense, I believe 656 | that, if there hadn't been the ecological crisis, in ten or twenty years of 657 | time we'd all have realized that there was a profound crisis of knowledge, even 658 | in the sense of scientific knowledge. In the sense that we don't manage anymore 659 | to integrate a vision of the world into a coherent image—since, after all, 660 | that's what we want to achieve—into a vision of reality that enables us to 661 | interact favorably with it from our own little slices of speciality. This is a 662 | second aspect that seems to me to have become harmful. 663 | 664 | There's a third, related to this one. It's that specialties order themselves 665 | spontaneously, according to objective criteria of subordination to one another; 666 | so that we see a stratification of society, starting with the stratification of 667 | science, according to so-called objective criteria of subordination of 668 | specialties to one another. In this sense, science, in its current practice as 669 | it has developed over the last three or four hundred years, seems to me to be 670 | the main ideological support for the stratification of society, with all the 671 | alienations that this implies. I believe that, in this respect, the scientific 672 | community is a kind of microcosm that fairly accurately reflects the trends 673 | within global society. 674 | 675 | Furthermore, fourth point, is the separation in science between knowledge on 676 | the one hand, and desires and needs on the other. Scientific knowledge is 677 | developed according, supposedly, to an internal logic of knowledge, according 678 | to so-called objective criteria for the pursuit of knowledge. But in fact, it 679 | moves further and further away from our true needs and desires. The most 680 | striking thing in this respect seems to me to be the state of relative 681 | stagnation in which agriculture has found itself in the four hundred years 682 | since the development of the exact sciences, when compared with fast-growing 683 | branches such as mathematics, physics, chemistry and, more recently, biology. 684 | Agriculture, after all, has been the basis of our so-called civilized societies 685 | for ten thousand years. It is truly society's basic activity, from which we 686 | derive most of the resources we need to satisfy our material needs. One might 687 | have thought that, with the development of new knowledge methods, they would be 688 | applied to agriculture as a matter of priority, freeing us, to some extent, 689 | from having to work excessively to satisfy our basic needs. This has not been 690 | the case. Even today, I believe that for most of us, agriculture is not 691 | considered a science. It would seem unworthy of a brilliant mind to care about 692 | agriculture. Now precisely, with new scientific techniques, the first thing to 693 | ask is "What's the use of science, the content of the science we're 694 | developing?" I believe that among the most important topics to be studied by a 695 | new science will be the development of new agricultural techniques that are 696 | much more efficient and, above all, much more viable in the long term than the 697 | techniques that have been used until now. 698 | 699 | Here are a few criticisms of current scientific practice. Based on what I've 700 | heard of some innovative attempts, I'm convinced that we can overcome these 701 | limitations of current science, and that we can therefore develop a science that is 702 | directly and constantly subordinated to our needs and desires; in which there is 703 | no longer an arbitrary separation between scientific activity and all our modes 704 | of knowledge; where there is no longer any arbitrary separation between science 705 | and our lives. At the same time, the human relations promoted by scientific 706 | activity would change completely. Science would no longer be the property of a 707 | caste of scientists, science would be science of all people. It would not be 708 | done in laboratories by certain highly regarded individuals to the exclusion of 709 | the vast majority of the population. It would be done in the fields, in the 710 | gardens, at the bedside of the sick, by all those who take part in production 711 | in society, that is, the satisfaction of our real needs—in other words, by 712 | everyone. 713 | 714 | So science truly becomes everyone's science. For the *New Alchemists*, this 715 | group I've already alluded to, it's even a technical necessity. Indeed, their 716 | intention, their starting theme, was to develop biotechnologies which would 717 | allow, with extremely rudimentary means that don't call on the industrial and 718 | technological hyperstructure, to create artificial ecosystems highly productive 719 | in food. Technological means in the ordinary sense—such as the introduction of 720 | a continuous source of energy (electricity), or the supply of food by chemical 721 | industries (the fertilizers or feed for livestock or fish)—can be replaced by 722 | a sophisticated and comprehensive knowledge of the natural phenomena within 723 | these artificial ecosystems. To achieve this, they convinced themselves that 724 | this could not be achieved within existing academic structures. In fact, it 725 | wasn't even possible to do it inside closed laboratories, it could only 726 | be done in the field, because the development of these techniques had to take 727 | into account subtle ecological factors that vary enormously from one ecological 728 | microsystem to another—of which there are thousands and tens of thousands of 729 | them in a country like the United States, where they pursue their operations. 730 | 731 | So, to develop these methods, we need to develop them in the field and everyone 732 | must join in virtually. The *New Alchemists* are in contact with millions of 733 | Americans interested in agrobiology, organic gardening and farming, through the 734 | intermediary of their *Organic Gardening and Farming* magazine[^10]. Among them 735 | are thousands of small people, small farmers, small gardeners, who have written 736 | to them to join their research into the development of such ecosystems. So, 737 | currently, it's not just a matter of ideas in the air, but of things that are 738 | being done in a country as radically opposed to this kind of spirit as the 739 | United States. Once again, by cause of concrete details that John Todd, one of 740 | the founders of the *New Alchemists*, told me, it's absolutely impossible to 741 | promote this kind of research within existing academic structures.

In fact, it's true that insofar as by 791 | science we mean scientific activity as it is practiced today, I've come to the 792 | conclusion that, in many respects it is one of the main negative forces at work 793 | in today's society. This was probably not the case two hundred years ago, and 794 | perhaps not even even a hundred years ago. Today, I believe the situation has 795 | greatly changed. But then again, as I said earlier, I think that today's 796 | scientific activity is likely to change very, very profoundly. I don't think 797 | this will happen without most of the current scientific sectors simply 798 | withering away. I'm absolutely convinced that current research—which involves 799 | cataloguing elementary particles corresponding to such and such operators in 800 | the Hilbert space, or the mathematical research I've been involved in so 801 | far—will wither away, not by an authoritarian decree from me or anyone else, 802 | but spontaneously. And this, when the current structures of society will 803 | collapse, when the cogs no longer work, because the mechanisms of industrial 804 | society are self-destructive—they destroy the environment, and fortunately 805 | for us I'd say. So they can't go on working indefinitely, they set irreversible 806 | processes in motion. So that there will be a collapse of our current lifestyles. 807 | When our cities, for example, collapse, when no one pays the wages that have 808 | enabled us, thanks to esoteric scientific activity, to buy in the shops the 809 | groceries we need, to buy clothes, to pay our rent and so on—and even if we 810 | had the money, it would be of no use to us, because we'll have to dig it out of 811 | the ground ourselves, because there won't be enough left—at that exact point, 812 | the incentive to study elementary particles will disappear entirely. 813 | 814 | I myself was quite fanatical, if you will, about research. I was really very 815 | captivated; there are noble passions. But even supposing physicists 816 | remain—despite the extremely strong pressure of material necessities of 817 | survival—who would dream of continuing their research, we mustn't forget that 818 | a particle accelerator isn't made from a few pieces of wood. It's something 819 | that requires considerable social effort, and I doubt very much that the other 820 | members of society will be willing to distract themselves from the activities 821 | that are really necessary to establish a world worth living in, to rebuild 822 | particle accelerators and the like. In any case, I believe that, for 823 | accelerators and other such devices, the general public has never been 824 | consulted. Moreover, I would add that if it had been, it would probably have 825 | been consulted in such a way as to ensure that it would have said "Amen!" 826 | 827 | After the lessons, that each of us who survives, will be able to draw from the 828 | events accompanying the collapse of industrial society, I believe that 829 | mentalities will have profoundly changed. That's why scientific research will 830 | cease, it won't be because this or that person has decided that we will no 831 | longer be doing scientific research from now on. It will simply cease, as 832 | something that, by general consensus, has become entirely uninteresting. We 833 | won't want, simply, I'm convinced, to do scientific research. That doesn't 834 | mean we won't want to do any research at all. Research, our creative 835 | activities, will go in completely different directions. 836 | 837 | I'm thinking, for example, of the kind of research being carried out by the 838 | *New Alchemists* with thousands of little people who have no university 839 | training. These are fascinating things that will challenge the creativity of 840 | each and every one of us in ways as profound and perhaps as satisfying as 841 | ultra-specialized laboratory work is today. 842 | 843 | We've been raised in a certain ambient culture, in a certain system of 844 | references. For many of us, according to the conditioning from elementary 845 | school onwards, we see society as we know it as the ultimate evolutionary 846 | achievement, the *nec plus ultra*. At least, most scientists do. But we forget 847 | that there were hundreds and thousands of civilizations before ours, with 848 | cultures that were born, lived, flourished and died out. Our civilization—or 849 | rather, industrial civilization, because I no longer consider it my own—will 850 | be no exception. 851 | 852 | One thing that goes beyond this remark, in my opinion, is to realize, that this 853 | is a process that's really in front of of us, in which we're already engaged in 854 | right now. In fact, the ecological crisis, the civilizational crisis is not 855 | something to happen in another ten or twenty years: we're right in the middle 856 | of it. In fact, I believe that more and more people are realizing this. It's 857 | something that's struck me more and more over the last few weeks and months, 858 | the extent to which people for whom we were least expecting it, started feeling 859 | it. We scratch just a little bit underneath the superficial things they say, 860 | and we notice there's a real sense of disarray about, let's say, the overall 861 | sense of the ambient culture. 862 | 863 | Here is to the accusation of nihilism. So, there's some truth in it if applied 864 | to a certain form of scientific activity. I've somewhat forgotten the other 865 | objections you were making? 866 | 867 | > We owe life to science! 868 | 869 | I think there are some useful things to say on the subject. Assuming that some 870 | people here owe their lives to science, it's fair to say that there are 871 | hundreds of thousands of people in Vietnam who also owe their deaths—and their 872 | deaths under atrocious conditions—to this same science. This is a rather 873 | facile argument because there are many people who say: "Science has been 874 | misused, the remedy is to still do the same kind of science, but now to put it 875 | in the hands of people who will use it well." We'll be told, for example, that 876 | medicine, biological research, etc., is the kind of science that is mostly used 877 | for good. Here again, there's an easy way to respond by saying: the same kind 878 | of fundamental research in biology which, through engineering work will, for 879 | example, be used to develop vaccines against polio or other diseases, this same 880 | kind of fundamental research, through other engineering work, will be be used 881 | to produce strains of highly pathogenic microbes, highly resistant to all 882 | antibiotic agents, and will be used in bacteriological warfare. So, in the end, 883 | research has no smell, and whatever the intentions of those promoting a certain 884 | type of research—at least the type of research that is currently being 885 | promoted within our traditional science—experience has shown that it is 886 | always divertible and diverted. 887 | 888 | As I've given the example of bacteriological warfare here, we could say that 889 | the two examples are somewhat similar. In the sense that they can be linked to 890 | an accident, namely the existence of military apparatuses, the existence of 891 | antagonistic nations. But let's suppose that these difficulties are eliminated, 892 | that the dream of the global citizens is realized, that there would be a world 893 | government. Or suppose that the United States, Russia or China, as the case may 894 | be, had absorbed the entire planet, that there was only one country left. Or 895 | suppose that the planet is smaller than it is and that it solely consists of 896 | the United States, or let's suppose that the United States, through an 897 | extreme isolationist policy is able to live in closed loop, and let's look at 898 | what's happening over there. I would argue that, in fact that the problems are 899 | deeper than that, that the essential problems still arise even if there were no 900 | longer any military problems. 901 | 902 | Take, for example, the antibiotics, which you mentioned, precisely because they 903 | effectively save human lives. What do we see about the use of of antibiotics? We 904 | see that, when we have the slightest cold, any ailment whatsoever, we go to the 905 | doctor. What does he prescribe? Antibiotics. In fact, for a simple case of 906 | fatigue, very often he prescribes antibiotics. It seems he is under some kind 907 | of social pressure, namely, his client expects him to prescribe each time the 908 | remedy that is likely to bring about an improvement as quickly as possible. And 909 | this, without prejudice to what will happen in the long term. Any biologist 910 | will tell you, you don't need to be a genius to know that, and even I know that 911 | while not a biologist, that the routine use of antibiotics is an absurdity. 912 | Indeed, through this practice, we contribute to the formation of strains of 913 | microbes in our bodies that will develop resistance, precisely to the 914 | antibiotics we take. Such that, in truly serious cases where urgent 915 | intervention using antibiotics could save our lives, we risk being left out in 916 | the cold. Now, we're in a situation where it's difficult to assess the benefits 917 | or advantages of antibiotic use. Which outweighs the other? Do the tens of 918 | thousands of lives saved by the use of antibiotics outweigh, say, the millions 919 | of organisms whose natural resistance to microbial agents has been weakened by 920 | the indiscriminate use of antibiotics? 921 | 922 | I'm not going to settle this issue, but I'd simply say that the question here 923 | is not a question of technology, it's not a question of knowledge. It's quite 924 | clear that biologists have the necessary knowledge to decide, right now, that 925 | the use that doctors make of it, in the clinic and in their day-to-day 926 | practice, makes no sense. It's a question of lifestyle. It's a question of 927 | civilization. In fact, I'm not saying that we must necessarily ban antibiotics 928 | in an future ideal society. Antibiotics are fungi that can be produced with 929 | extremely rudimentary means, without using the large-scale hyperstructures of 930 | heavy industry. Antibiotics could well be used in a highly decentralized 931 | society of communities of a few hundred or a few thousand inhabitants living in 932 | relative autarky. It is possible and probable that antibiotics will continue to 933 | be used in post-industrial societies, at least in some of them. Just because 934 | they were produced in our current Western scientific culture does not mean that 935 | there should be a blanket ban on this kind of process. I think that we have to 936 | judge on the evidence, and that it's not a matter of theoretical work to be 937 | done now, namely: to separate the wheat from the chaff in the body of our 938 | scientific knowledge and the techniques currently available. This is, I 939 | believe, a job that will be done day-to-day, according to the needs of the 940 | moment. In other words, it's a job that will not be done by a few specialists, 941 | biologists, doctors, psychiatrists, physicists, etc. It will be done by 942 | everyone, as and when the need arises. We'll see what we need from the great 943 | mass of scientific knowledge—most of which I'm convinced is perfectly useless 944 | and will wither away completely. 945 | 946 | > What about relations between CERN and the military? 947 | 948 | I have no secret information on this subject. I wasn't claiming to be talking 949 | about, let's say, any real, official, or occult relations, between CERN and the 950 | military apparatus. I have no knowledge of such things. I wanted to talk about 951 | the image that the name CERN has on a large part of the more or less educated 952 | public, myself included. The name itself: Centre Européen de Recherche 953 | Nucléaires \[European center for nuclear research\]; the fact that it's an 954 | organization that brings together a number of countries; the prestige attached 955 | to it, which I'm sure you won't deny; the fact that it's research concerns at 956 | least the atom, even if it's not "nuclear research"; and that, linked to the 957 | public's growing preoccupation with, precisely, the atom, including the 958 | peaceful atom. All this creates a certain resonance with CERN that cannot be 959 | denied. Except that, as far as I'm concerned, in any case, the kind of 960 | research, the kind of scientific practice that is pursued at CERN—as at any 961 | other scientific institution today, but even more so because of the general 962 | connotations of atomic research with the perils to our survival—all this has 963 | the effect of creating discomfort, for many people I believe, and for me in 964 | particular. 965 | 966 | > What about Evariste Galois? 967 | 968 | He's dead, poor fellow. 969 | 970 | > You've pointed out a lot of bad things and I agree with you that they should 971 | > be changed.

But 987 | > is science responsible? What I mean is, three thousand years ago, do you 988 | > think it was fundamentally different? Thank you. 989 | 990 | I fully agree with you that most of the aspects of scientific practice that 991 | I've highlighted—at least some of them—are not specific to the world of 992 | scientific research. I don't think that there are necessarily more suicides, 993 | say, among mathematicians than in other professions. Why did I talk about it? 994 | It's simply because, despite everything, we talk better about the world we know 995 | first-hand. And I mentioned it, because there's a certain myth, that things are 996 | better in the scientific community, that, for example, scientific activity is 997 | necessarily a source of satisfaction, pleasure and joy. Meanwhile, in a number 998 | of cases, it can be shown that it is precisely scientific activity that is a 999 | source of constraint, repression and drama. I know of other cases in my 1000 | personal practice that are, let's say, less extreme than this one. But it's in 1001 | order to counter certain myths that I mentioned these cases. Otherwise, I 1002 | totally agree with your objection. So, in the end, I think there's a 1003 | misunderstanding, not an important difference in vision. 1004 | 1005 | As for the other question, I don't think science is the only cause of the 1006 | rather catastrophic situation we find ourselves in. I said at the outset that 1007 | it was one of the causes. In any case, if this cause didn't exist, the problems 1008 | linked, let's say, to man's survival would not exist today. They might arise in 1009 | a few centuries' time, but they wouldn't arise now. Of course wars like the one 1010 | in Vietnam could very well take place, and have taken place without the current 1011 | development of science. What's striking, I think, for a scientist, is the 1012 | extent to which the most modern techniques are applied in this war. I went to 1013 | North Vietnam and I was able to talk to the people concerned about the various 1014 | fragmentation bombs, for example. The fragments, balls, rotate very quickly, so 1015 | that they can tear flesh more easily, and also so that they can penetrate the 1016 | air-raid shelters which are dug out all along the streets and roads, for 1017 | perhaps no care had been taken to close them. And finally, they explode in the 1018 | air to better hit the civilian population. Moreover, despite the instructions, 1019 | most Vietnamese, because they want to see what's going on, don't close the 1020 | holes. So when the bombs go off, these shelters are rendered more or less 1021 | illusory. Similarly, metal balls have been replaced by plastic ones to make 1022 | their detection by X-ray impossible. New techniques must therefore be developed 1023 | to extract these beads from the shredded flesh. The military technology 1024 | employed in Vietnam is geared more towards mutilating the population than 1025 | direct extermination, because a mutilated person requires the care of many 1026 | other people to keep them alive, whereas a person who has been killed requires 1027 | very little. So there are a number of quite atrocious aspects of technology 1028 | really linked to research, to the current state of science. 1029 | 1030 | One thing I didn't realize when I started thinking about these issues, is that 1031 | virtually every major American firms are directly involved in the manufacture 1032 | of armaments. This is true to a lesser extent for French firms. I don't know 1033 | about Swiss firms. At the time when I left the institute where I was 1034 | working—because 5% of the budget was of military origin—I had no problem 1035 | with the fact that most of the funds came from companies such as Esso, 1036 | Saint-Gobain and others. But since then, I've discovered that these firms are 1037 | very directly involved in the manufacture of armaments, all of them having 1038 | major contracts with the army. In such a way that, in the end, it becomes 1039 | impossible to distinguish between military research and research *per se*, and 1040 | even between, say, general-purpose firms and firms involved in the 1041 | proliferation of military devices. Eventually, I came to realize that 1042 | everything was inextricably linked. 1043 | 1044 | By the way, I realize there's a question I haven't answered, perhaps related to 1045 | Galois. It was the assertion that it was good to pursue scientific research for 1046 | its own sake, for the pleasure of knowledge, in the same way as one pursues an 1047 | artistic activity. So there are perhaps one or two things to be said here. 1048 | 1049 | The first is that, in order to understand and appreciate the kind of 1050 | mathematics that I was doing, for example, just three years ago—even if you 1051 | bypass the usual channels in teaching, if you go straight to the point, to the 1052 | essentials—you're looking at something like five to ten years of specialized 1053 | training. But it's clear that such training is, in the current state of things, 1054 | the appanage of a tiny minority of the population. Likewise, hundreds of other 1055 | mathematicians are doing equally esoteric things in their own corners. So that 1056 | in the end, those who manage to understand the kind of thing I was 1057 | doing—something I'd been pursuing intensely for a few years—are, what do I 1058 | know, maybe five, ten, fifteen, twenty people in the world, something like 1059 | that. So, the importance that mathematical activity can have from an artistic 1060 | point of view... let's say, mathematical activity is very different from the 1061 | importance of music, for example. To feel music, we don't need long training. 1062 | In fact, we don't even need to be born yet, because even an embryo, in its 1063 | mother's womb, already reacts to musical stimuli. I think a lot of people have 1064 | experienced this, at least my wife did. When there was jazz music, when she was 1065 | five or six months pregnant, the baby danced in her belly. Of course, when I 1066 | talk about art here, I'm talking about elementary art, art that we can 1067 | appreciate, and even make ourselves: music, drawing, pottery, things like that, 1068 | which require relatively little training. But it's true that in the arts, as in 1069 | the sciences, as in virtually all human activity, including physical activity, 1070 | the sports, the competitive aspect is becoming increasingly important. 1071 | Nowadays, when almost anyone says art, the reflex is to think of people like 1072 | Rubinstein, Gieseking or Heifetz, or Picasso and so on. In other words, we 1073 | immediately think of the great virtuosos of art, those who have reached a 1074 | position of extraordinary prestige. Finally, art becomes the prerogative of a 1075 | very small number of people who make art for us, by proxy, because it's 1076 | absolutely out of the question for each and every one of us to do the same in 1077 | our own lives. 1078 | 1079 | Now, this is another thing we could say on the question of what we mean by a 1080 | life worth living: it's a life which, precisely, contains its share of 1081 | creativity, including its share of artistic creativity. It's much more 1082 | important for each of us to be capable of being an artist in their own field 1083 | and at their own level, to produce music, to perform it on, say, a harmonica, a 1084 | piano or a guitar, and to derive direct pleasure from it. This pleasure, I 1085 | believe, will be infinitely more profound than the pleasure one might derive 1086 | from listening to a record by Heifetz or Gieseking. It's of a different nature, 1087 | in any case, it's at another level. Maybe one doesn't preclude the other, this 1088 | is is unclear. I have the impression that the kind of mentality that prevails 1089 | among the great virtuosos—which makes them perform, for example, five hours 1090 | of scales a day, day after day—ends up killing much of the joy they feel in 1091 | making music. And this is necessary if they are to keep up in the fierce 1092 | competition between virtuosos. I think it's more or less the same as the 1093 | competition, sometimes unconscious, between scientists. Competition, which means 1094 | that people I know, including myself, spend fifteen hours of their day, day 1095 | after day for a long time, trying to develop mathematical theorems increasingly 1096 | sophisticated, increasingly esoteric. I have the impression that this type of 1097 | mentality will disappear in the generations to come. 1098 | 1099 | > You have realized that our world is a world where there is no dialogue.

That's not the point. If I predict that science, as it is currently 1126 | practiced, will wither away, that, for example, that the whole of mathematics, 1127 | more or less, will disappear in the next few generations, it will be a natural 1128 | decline, because people will no longer feel motivated to do it. So, to make a 1129 | parallel on a smaller scale—I believe it was in the first century of 1130 | our era—the science of hyperplane sections, conic sections and conic bundles 1131 | had reached such a degree of complexity that the mathematicians of the time 1132 | thought it was the end of mathematics, because, in any case, going further, 1133 | things would become so complex that it would be impossible for the human mind 1134 | to make sense of them. What happened was that, purely and simply, we dropped 1135 | this kind of speculation, and mathematics has continued along entirely 1136 | different paths, and it's clear that mathematics has not stopped producing new 1137 | facts to the present day. In the same vein, I think that the direction of 1138 | research that has developed over the last 400 years, let's say, in a certain 1139 | spirit, will wither away just alike, just as the human mind will take very 1140 | different avenues. Not in a coercive way, simply because it will no longer be 1141 | practiced. There will be other imperatives linked to our real needs. 1142 | 1143 | I think that agriculture, stockbreeding, decentralized energy production, 1144 | medicine of a certain kind, very different from the medicine that prevails 1145 | today, will come to the fore. It's impossible to say which part purely 1146 | creative joy will play in these new developments. My hope is, it will be a 1147 | creative development in which there will be no essential difference between 1148 | conceptual activities and manual physical activities. When people become 1149 | masters of their own needs to the point where an appreciable part of their 1150 | creativity remains free—and this will take a time we can't predict, it may be 1151 | a generation, it may be ten, no one knows—at that point, anyone, not just a 1152 | certain scientific elite, will be able to devote a significant part of their 1153 | time to purely creative, purely speculative, purely playful research. Even if 1154 | we resume research directions that may have been abandoned in the meantime, for 1155 | example, certain directions in current mathematics or even physics—if society 1156 | is prepared to take them on, because today's physics isn't just done with your 1157 | head, it's done with serious instrumentation, with capital outlays, involving 1158 | the mobilization of significant collective energy—then I have no problem with 1159 | it; but I think it's absolutely impossible to predict it now. In any case, I 1160 | agree with you that freedom is an essential criterion for the directions to be 1161 | taken, well, for me it certainly is. I believe that nothing new will be created 1162 | without freedom, and even, once again, that the decline of present-day science 1163 | will increase our freedom, and this will not be at the expense of anyone's 1164 | freedom. 1165 | 1166 | About your picture of the angel and the daemon, I don't believe in this 1167 | dichotomy of good and evil. I don't share that view, rather, there's a complex 1168 | mixture of two opposing principles. If you don't mind, I'd like to do a little 1169 | philosophical digression on the subject of mathematical thinking and its 1170 | influence on general thinking. One thing had already struck me before I came to 1171 | the overall criticism of science almost two years ago: the crudeness, shall we 1172 | say, of the mathematical mode of reasoning when confronted with the phenomena 1173 | of life, with natural phenomena. The models provided by mathematics, including 1174 | logical models, are a kind of Procrustean bed for reality. A special thing 1175 | about mathematics is that every proposition, putting the logical subtleties 1176 | aside, is either true or false; there is no middle ground between the two, the 1177 | dichotomy is total. Actually, this doesn't correspond at all with the nature of 1178 | things. In nature, in life, there are no propositions that are absolutely true 1179 | or absolutely false. In fact, to fully grasp reality, it is often necessary to 1180 | take into account seemingly contradictory aspects, or at any rate, 1181 | complementary aspects, and both are important. From a more elementary 1182 | standpoint, no door is ever completely closed or completely open, this doesn't 1183 | make sense. This dichotomy, which perhaps stems from mathematics, from 1184 | Aristotelian logic, has really permeated our way of thinking, including in 1185 | everyday life and in any debate about ideas or even personal life. This is 1186 | something I've often noticed when talking to people, whether in private or in 1187 | public. In general, people see two extreme alternatives and see no middle 1188 | ground between the two. If the person I'm talking to has chosen a certain 1189 | alternative and I have a vision that lies beyond the one they considers good, 1190 | they'll immediately accuse me of having chosen the opposite extreme alternative, 1191 | because they can't see the middle ground. 1192 | 1193 | I think there's an inherent flaw in the mathematical way of thinking and I have 1194 | the impression that it's also reflected in this Manichaean vision of human 1195 | nature. On the one hand, there's the good, and on the other, the bad, and in 1196 | the best case scenario, we see both living side by side. I have the impression 1197 | that what we call bad is just a natural reaction to a certain number of 1198 | repressions we've been subjected to since birth; in a way, they're just as 1199 | natural, just as necessary as, for example, the appearance of fever: a sign 1200 | that our body is reacting to a microbial invasion. The doctor's task is not to 1201 | eliminate the fever, but to try to combat the microbial invasion with drugs. 1202 | This, at least, is the official thesis. Perhaps the task of the physician of 1203 | the future will be above all to understand the psychosomatic cause of microbial 1204 | proliferation at this time rather than another, since there are always microbes 1205 | in the environment, and we're exposed to them all the time: what are the real 1206 | causes? What stresses have we been subjected to that make us vulnerable? But 1207 | that's a different kettle of fish. So, I have the impression that the Manichaean 1208 | vision isn't very good. It's part of the air we breathe with the prevailing 1209 | culture, and I believe that this vision will continue to change. 1210 | 1211 | > You think that this view of right and wrong is air we breathe and that it 1212 | > comes from mathematics. I think the opposite is true. Modern mathematics is 1213 | > younger than all our medieval philosophy or even theology.

Bourbaki traces it back to the 1232 | Greek mathematicians, let's say from Pythagoras onwards. So it's already a very 1233 | old tradition. Take Euclid, for example, who developed this systematic spirit 1234 | in absolutely perfect fashion, such as which was taught until not so long ago. 1235 | It's possible, then, that mathematics has something to do with this state of 1236 | mind; even if there isn't—I can't swear to it—a causal effect. Finally, the 1237 | fact that the two things go in the same direction, mathematical dichotomy and 1238 | Manichaeism, or this tendency to see only two extremes of an alternative, it 1239 | can hardly be chance. There's certainly a correlation between the two. These 1240 | things are linked in the dominant culture. This dominant culture, in any case, 1241 | is not new. I think it's been developing for over two thousand years. I'm not 1242 | very well versed in history, but, for example, people like Jacques Ellul and 1243 | Lewis Mumford[^5], for example, have precisely studied the ideological ins and 1244 | outs of science and technology from its very origins. As far as Mumford is 1245 | concerned, it seems to me that he dates it back already to the time of the 1246 | Pharaohs, of the great works of Egypt. So, I believe that our ancestors, in 1247 | this respect, go back quite a long way. 1248 | 1249 | But there was another question I believe? 1250 | 1251 | > \[inaudible\] \[...\] the part that serves of demystification or denunciation 1252 | > of the role of science and, above all, the motivation of the scientist, even 1253 | > if this is perhaps incomplete.

In fact, I've spoken from my personal experience, my personal 1279 | practice, as an illustration of a type of action, of conclusions, that can be 1280 | drawn when confronted with certain contradictions. However, it is absolutely 1281 | not my intention to set myself up as a model for anyone. I realize that the 1282 | conditions are extremely different, both the so-called objective conditions, 1283 | and also the subjective conditions, let's say, the state of readiness required 1284 | to make draconian steps, such as the one I made when I left the institute where 1285 | I worked, and a little later when I decided to stop scientific research. Which, 1286 | by the way, doesn't mean I'm not still paid to teach, last year and this year, 1287 | very esoteric science at the Collège de France \[prestigious higher education 1288 | establishment\], and that next year I'll either be teaching at the Orsay 1289 | faculty of science or research director at the Centre National de Recherche 1290 | Scientifique \[CNRS, french national research agency\]. In other words, I won't 1291 | have escaped the contradiction of my scientific status. 1292 | 1293 | In the end, what counts for me is not so much achieving the position of moral 1294 | purity, which is perfectly impossible within this society—that's one of the 1295 | many things I've learned over the last two years—what counts is that we are a 1296 | ferment of transformations, a factor of transformations wherever we find 1297 | ourselves. Of course, if we find ourselves in a certain professional 1298 | environment, it doesn't necessarily mean to leave that professional 1299 | environment. But what I'm convinced is that this transformation won't be 1300 | achieved by the magic virtue of joining a certain party or, from time to time, 1301 | handing out leaflets, join certain unions, or cast ballots. I'm entirely 1302 | convinced that this kind of transformation will start with personal 1303 | relationships. Insofar that if personal relationships don't change 1304 | profoundly, nothing will. If we think that personal relationships can only 1305 | change after structures have changed—which means that everything is postponed 1306 | until the big D day of the revolution—then the revolution will never come, or 1307 | the revolution that does come won't change anything. In other words, it will 1308 | put a technocratic management team in the place of another technocratic team, 1309 | and industrial society will walk its way just as before. 1310 | 1311 | As an example of relationships that will have to change radically, I'm 1312 | thinking, for example, of the relationship between teachers and students. I'll 1313 | be confronted with this situation as early as this autumn. It's the first time 1314 | in my life that I'll be in a lecture hall with students to whom I should teach 1315 | for real the mathematics that will prepare them for certain exams, give them 1316 | certain diplomas, which I'm convinced are useless. First, they're of no use to 1317 | society as a whole, and second, it's not even clear that they're of any use to 1318 | those who will have these diplomas, because it's not at all clear that they'll 1319 | have a job afterwards. Even today, most scientists either refuse to see the 1320 | problem or, if they do, put a demure veil over it in their relations with 1321 | students. The relationships between students and scientists are hence 1322 | traditional teacher-student relations; in other words, they give a technical 1323 | lecture, the one they've been asked to give, and that's it. When, 1324 | exceptionally, students ask technical questions, we answer them as best we can, 1325 | and that's it. As far as I'm concerned, I've decided not to stick to this type 1326 | of relationship, to no longer separate mathematical teaching from a 1327 | cards-on-the-table discussion with students—or anyone else who wants to join 1328 | in—to review: why are we here? What are we going to learn together? Why? What 1329 | does the exam at the end of this year's program mean? What is its meaning? What 1330 | is our mutual role, me as teacher and you as students? And finally, deciding 1331 | together what we're going to do. No doubt, in the first few years, unless the 1332 | situation matures even faster than I anticipate, it's likely that the majority 1333 | of students insist that, once these discussions are over, we follow more or 1334 | less the traditional program and the customary ritual of the exams. It's also 1335 | possible that they'll decide otherwise, in which case I'll go along with their 1336 | opinion. In any case, there's the possibility of a dynamic exchange, and a 1337 | maturing of the general atmosphere. 1338 | 1339 | In fact, I started putting these ideas into practice this very year at the 1340 | Collège de France, where I had announced, as the first part of the planned 1341 | mathematics course, a discussion on the same theme as today's discussion. This 1342 | proposal gave rise to a lively debate among my colleagues at the Collège de 1343 | France. For the vast majority of them, it was unthinkable that a mathematics 1344 | course could be partly and officially devoted to a question of this type. In 1345 | fact, the longer title was: "Science and technology in the current evolutionary 1346 | crisis. Will we continue scientific research?" So I was putting forward the 1347 | question of the crisis of civilization, which seems to me to be the urgent 1348 | issue to be debated at the moment. Now, as perhaps for the first time, or one 1349 | of the few times that, in this august institution, is raised a truly burning 1350 | question for the civilization in which we find ourselves, and that we propose 1351 | to discuss it publicly and in depth, it's practically the only time that the 1352 | assembled faculty has refused to give its approval to this course. In fact, the 1353 | vote was something like thirty-five against and nine in favor, and I myself was 1354 | surprised to find nine colleagues supporting my initiative. This surprise was, 1355 | I'm sure, much greater among the other thirty-five. From the tone in which this 1356 | discussion was taking place, it was clear that, for them, it was unthinkable 1357 | that a scientist in his common sense could fail to be shocked by the kind of 1358 | proposal I was making for this, supposedly, mathematics class. 1359 | 1360 | This, of course, is just an example, not to say that anyone can do the same 1361 | thing, but as a concrete example of what, I personally, try to do, to make the 1362 | most of a simply contradictory situation. Instead of trying to hide these 1363 | contradictions, I try to explode them as brutally as possible, and this as a 1364 | way of maturing a certain situation. 1365 | 1366 | > You've made constant reference to scientific research, but I have the feeling 1367 | > that you use the term too narrowly. It seems that for you it's mathematics of 1368 | > course, then physics, something like that, at a pinch medical research.

I'm 1386 | > afraid that inevitably you'll fall back into either religion or science, 1387 | > because either you're making apocalyptic prophecies or you're trying 1388 | > to reinvent with your students science that's already been done. 1389 | 1390 | You speak of an apocalyptic vision of civilization, and this is a term that 1391 | comes up a lot when we talk about civilization. It's always this same 1392 | conditioning that makes us think there's only one civilization, as if there 1393 | weren't hundreds, and as if there won't be hundreds more to come. So, first of 1394 | all, a point I'd like to reiterate, in my vision at least: it's that we're 1395 | talking about a certain kind of civilization, which we can well and truly 1396 | reject, and which we can well and truly predict will disappear like many 1397 | others. When, almost two years ago, I envisaged the disappearance of 1398 | civilization, I was still too caught up in my own conditioning: I identified 1399 | civilization, the only one I knew, with humanity. The destruction of 1400 | civilization appeared to me as an apocalyptic image of the end of the human 1401 | species. However, half an hour or an hour ago, I explained that this vision has 1402 | now entirely changed. The collapse of this civilization is not an apocalyptic 1403 | vision; it is, let's say, something highly desirable. I even consider it our 1404 | great good fortune that there is, let's say, a biological basis of human 1405 | society that refuses to follow the path of the dominant industrial 1406 | civilization. In the end, the ecological crisis will force us, whether we like 1407 | it or not, to change our course and develop lifestyles and modes of production 1408 | radically different from those of industrial civilization. 1409 | 1410 | Also, when you talk about the role of the human sciences, you're saying that 1411 | there's not only the so-called exact sciences; I'm well aware of that. You also 1412 | know as well as I do—and this is a very serious criticism that we can make of 1413 | the human sciences—that they are increasingly trying to mould themselves to 1414 | the model of the so-called exact sciences, mathematics in particular. In such a 1415 | way that, to the extent that the human sciences want to achieve true scientific 1416 | status—since only science according to universally accepted standards is 1417 | considered serious—these humanities are increasingly confined to a jargon 1418 | that is often mathematical. We know the influence of numerical tests and 1419 | quantitative methods, in psychology for example. We could also point out that 1420 | that a good number of economics treatises, big ones, begin, for two-thirds of 1421 | the book, with heavy mathematical formalisms whose only purpose is to make them 1422 | incomprehensible to mere mortals. A professor of economics in Bordeaux 1423 | literally told a friend of mine that the purpose of this mathematical formalism 1424 | in a book of his own was to hide the fact that the true scientific content 1425 | could be understood by anyone with the level of education of the Certificat 1426 | d'Études \[primary education certificate\]. We can thus make a very serious 1427 | reproach to the humanities in this respect. 1428 | 1429 | Moreover, the human sciences are subject to misappropriation, and hence subject 1430 | to the same criticism as other sciences. For example, in the penultimate issue 1431 | of *Survivre*, we go into some detail about the use of anthropology in the 1432 | South-West Asian war. In fact, American anthropological science is largely at 1433 | the service of the military: in order to map out the indigenous populations in 1434 | South-West Asia; in order to study by computer the impact of such and such 1435 | policy, such as burning crops, for example; in order to know whether the 1436 | fallout will be more beneficial to American settlement or, on the contrary, 1437 | resentment might prevail. Studies like these are carried out in the field by 1438 | anthropologists. 1439 | 1440 | In the end, I don't think there's that much of a difference to be made on the 1441 | practical and ideological role, between the humanities and the so-called exact 1442 | sciences, let's say the natural sciences. 1443 | 1444 | > I'd like to ask you about the aims of the *Survivre* movement and what 1445 | > contacts you have with existing movements in the region, such as the *Comité 1446 | > Bugey-Cobaye* \[Bugey guinea-pig committee][^16]. 1447 | 1448 | What are the goals of the *Survivre* movement? In the beginning, our vision was 1449 | apocalyptic and our aim was to fight for the survival of the human species, 1450 | threatened by the dangers of military conflict and the ecological crisis, 1451 | caused by pollution and the depletion of natural resources. But in the year and 1452 | a half of existence, we've evolved quite a bit, and I think the way most of us 1453 | see our purpose is the following: to help prepare for the transition from one 1454 | type of civilization to another through immediate transformations. Up until 1455 | now, our work has mainly been critical. Nevertheless, it's been a long time, 1456 | six months, since we've been able to see quite clearly that we need to move 1457 | past critical work to be able to do something in a constructive direction. For 1458 | example, disseminating information about the community movement on the 1459 | development of light technology, of biotechnology, in the sense of the *New 1460 | Alchemists*; disseminating information on the experiences of new schools like 1461 | Summerhill[^8] and things like that. But, between the intention to do it and, 1462 | let's say, the preparation from the point of view of experience, from the point 1463 | of view of contact, and so on, there's another step. I think that this 1464 | transformation, in the content of the journal and our action, will take place 1465 | gradually, over the coming year or years. I hope that within a year, for 1466 | example, at least half of the publications we put out, whether newspaper or 1467 | otherwise, will be in this constructive direction, rather than being purely 1468 | critical. 1469 | 1470 | As for our relations with the *Comité Bugey-Cobaye*, well, we're on good terms 1471 | with them! Five *Survivre* members took part in *Bugey-Cobaye*'s big 1472 | party-event last June. We're in fairly close contact with them. We even had 1473 | someone at the picket in front of the Bugey nuclear power plant for a month or 1474 | two last autumn. He was a member from the Hérault region, an editor of *Le 1475 | Courpatier*[^2], a small regional ecological newspaper in Provence. 1476 | 1477 | From a practical point of view, one of the useful things we can do, say, as a 1478 | specific action, particularly because we're a lot of scientists within Survivre 1479 | and are therefore better placed than many others, is to help denounce a certain 1480 | number of scientific myth, and we're going to start vigorously in this 1481 | direction from starting with issue no. 9 of *Survivre*. Its editorial is devoted 1482 | to a new critical description of scientism, with the title "The New Universal 1483 | Church"[^12]. 1484 | 1485 | On the other hand, we believe that a very important phenomenon is taking place. 1486 | Namely, the growing number of people isolated in their corners, or in their 1487 | family, or professional environment, who are beginning to be aware of the 1488 | existence of a real, civilizational, crisis. They feel isolated and thus 1489 | paralyzed, and we want to contribute to create a network of contacts between 1490 | these people. In fact, this network is is in the process of being set up 1491 | through all kinds of factors; I believe that, for example, Fournier's articles 1492 | in *Charlie-Hebdo*[^14] contributes to it, and I think the existence of our 1493 | group also contributes to it. Moreover, this phenomenon of creating a network 1494 | of links between previously isolated entities applies not only to individuals, 1495 | but also to groups. For example, for quite some time, the *Survivre* group 1496 | believed it was the only one of its kind to critically analyze science. But we 1497 | have since realized that similar groups are springing up all over the place. We 1498 | are particularly familiar with LASITOC[^9] and another group in the United 1499 | States, *Science for the People*[^15]. There are other groups created more or 1500 | less simultaneously with us and under the same name "survival" in the USA. 1501 | These groups, each based on a specific aspect of the crisis of civilization, 1502 | are gradually broadening their starting point along with all kinds of other 1503 | groups, sometimes starting from very different points. I have the impression 1504 | that this extremely rapid process will be completed in the coming year. In 1505 | other words that anyone in Western society, at least anyone who begins to sense 1506 | quite clearly that something is not quite right from a civilizational point of 1507 | view, who begins to be gripped by a feeling of incoherence in his own 1508 | life—but an incoherence with a global meaning—it will be impossible for him 1509 | to be isolated, he will immediately find himself in this network. It's a 1510 | process to which a group like ours can make an excellent contribution. These 1511 | are fairly modest things, which everyone does in their own sphere of activity, 1512 | but as there are so many people and groups doing it, the overall effect is by 1513 | no means negligible. 1514 | 1515 | — So, that sounds like a good conclusion to the questions, because I 1516 | think we can go on all night, but we've got to come to an end sometime. I think 1517 | we can thank you very much, because a lot of very profound points have been 1518 | treated and many aspects of these problems are certainly worthy of further 1519 | reflection. We'll be continuing this kind of discussion next time with another 1520 | speaker. 1521 | 1522 | — Just if I can add anything? Of course, if there are people here 1523 | who would like to continue, let's say, discussing certain points in 1524 | particular—I don't know, can we do it here on the spot? 1525 | 1526 | — It would be better to continue downstairs. 1527 | 1528 | — Right. Because in my personal experience, in the end, the discussions that 1529 | take place in small groups, after the fact, once the meeting's adjourned, are 1530 | more fruitful, are more interesting than the general discussion, 1531 | which was particularly orderly here, but which in general is much more 1532 | anarchic, much more chaotic—I see we're dealing with scientists, in other 1533 | words, disciplined people. \[laughter and applause\] 1534 | 1535 | [^1]: The *New Alchemy Institute* is a group of agrobiology researchers founded 1536 | by Dr. John Todd and Dr. William McLarney in Woods Hole, Massachusetts, USA 1537 | ("The Book of the New Alchemists", ed.

Je suis tombé sur un [entretien 5 | avec Leïla Schneps](https://www.youtube.com/watch?v=V8BbFTEyvIw), qui a été 6 | boulversée par la lecture de son *Esquisse d'un Programme* vers 1991, et qui 7 | n'a pas par la suite jamais cessé de chercher ses traces. Bien que l'entretien 8 | soit, sans surprise, axé sur le sensationalisme d'un soit-disant mathématicien 9 | de génie, fantasque et torturé, avec des questions largement aveugles à un 10 | point de vue politique et empathique de sa personne, Leïla s'en sort 11 | remarquablement bien. Ci-dessous la transcription du court passage de 12 | l'entretien portant sur la période 1970--1990 de sa vie, qu'il considérait 13 | d'après Leïla comme la plus heureuse, "le dimanche de sa vie". J'ai légèrement 14 | édité l'oralité de l'entretien, pour plus de fluidité à la lecture 15 | ([verbatim](/fra-verbatim-leila-schneps.md)). 16 | 17 | Gauthier Depambour --- Dans ces années 1960, un autre grand changement dans la 18 | vie de Grothendieck c'est qu'il va se politiser, il va rencontrer des gens qui 19 | vont notamment le sensibiliser à la question de l'écologie. Il va devenir 20 | militant écologiste radical et il va même fonder une revue qui s'appelle 21 | *Survivre*. 22 | 23 | Leïla Schneps --- Oui mais ça c'est plus tard, en fait c'est très intéressant 24 | comme question. 25 | 26 | G.D. --- Mais ça commence dans les années 1960! 27 | 28 | L.S. --- Je crois que ça commence avant. Il faut savoir qu'il s'est marié, 29 | qu'il a eu trois enfants, qu'il habitait un pavillon à Massy Palaiseau, qu'il 30 | vivait vraiment comme comme un professeur de fac normal. Il s'est adapté à la 31 | vie qu'on attendait de lui. On dit souvent qu'il faisait jusqu'à seize heures 32 | de maths par jours. Il faisait tout le temps ça. C'était extrêmement difficile 33 | de lui parler d'autre choses, de lui parler de livres à lire, de cinéma, de 34 | films. En gros il faisait vraiment uniquement des maths. Et la question de ses 35 | intérêts politiques, qui quelque part viennent forcément de ses parents, et de 36 | son intérêt pour l'écologie, à quel moment ça a commencé chez lui, c'est 37 | difficile à dire. Ce qui est sûr c'est qu'il y a eu un bouleversement 38 | incroyable dans sa vie en mai 68. Je pense que pour lui c'était un moment 39 | énorme, où il a renoué avec ce qu'il était vraiment, ce qu'il avait écrasé. Il 40 | le dit lui-même: "J'ai stagné complètement pendant tout le temps que je faisais 41 | des maths, parce que je ne faisait que des maths." 42 | 43 | Il y a Michel Demazure, un de ses élèves qui est devenu un excellent 44 | mathématicien, qui raconte cette anecdote, où un jour, il a croisé Grothendieck 45 | dans la rue qui lui disait "Tu vas où?" et il a dit quelque chose comme "Je 46 | vais au concert". "Pourquoi tu fais pas des maths? Pourquoi tu fais autre 47 | chose?" lui demande Grothendieck. Et une dixaine d'années plus tard, donc après 48 | la grande rupture, il l'a recroisé dans la rue et il a dit "Qu'est-ce que tu 49 | fais ses jours-ci?" ce à quoi Démazure répond: "J'essaie de démontrer machin 50 | truc." Grothendieck répond "Tu fais encore des maths?!" Donc c'était tout ou 51 | rien avec Grothendieck. Je sais pas ce qu'il pensait politiquement ni 52 | écologiquement avant 1968, ce que je sais c'est que c'était énorme pour lui, 53 | cette révolution étudiante, il se sentait complètement du côté des étudiants. 54 | Il a essayé de communiquer, mais les étudiants, en gros lui disait "Mais vous 55 | êtes un des mandarins, vous êtes précisément de ceux contre qui on se bat." Et 56 | pour lui c'était terrible. Tout d'un coup il s'est vu avec les yeux des autres 57 | et il n'a pas voulu ça. Mai 68, c'était le début de ce mouvement, qui a fini 58 | avec la rupture en 1970--71. Donc à partir de ce moment là on peut dire qu'il a 59 | ouvert les yeux, il qu'il est en train de tuer la personne qu'il est vraiment, 60 | de l'écraser. Et il a parlé très souvent parlé plus tard, dans un autre 61 | contexte, d'enterrement, on y arrivera peut-être. Je pense qu'il savait déjà ce 62 | que ça voulait dire, parce que c'est quelque chose qu'il avait fait à lui-même 63 | pendant de longues années. 64 | 65 | G.D. --- Justement cette rupture dont tu parles, des années 1970--71, provient 66 | du fait, aussi, qu'il est devenu très anti-militariste et qu'il ya eu une 67 | petite proportion, toute petite --- je crois que c'était 5% du budget de l'IHÉS 68 | --- qui provenait de fonds militaires. Il a essayé de se battre pour que ce 69 | budget, ces 5% là, soient abandonnés, et comme ça n'a pas été abandonné il a 70 | claqué la porte de l'IHÉS. Il est allé au Collège de France, et là il a 71 | commencé aussi à faire des cours, en expliquant que les maths, ça servait 72 | peut-être pas à grand chose. Il a essayé de politiser ses cours, et ça n'a pas 73 | plu non plus aux professeurs du Collège de France, qui l'ont viré. Après, je 74 | crois qu'il a fait un an à Orsay et il est revenu finalement à Montpellier, où 75 | il avait fait ses années de licence. 76 | 77 | L.S. --- Oui. Je tiens quand même à dire que tout est exactement comme tu l'a 78 | raconté, à ceci près que les fonds militaires que recevait l'IHÉS c'était un 79 | prétexte. Il y avait un conflit larvé avec le directeur de l'IHÉS Léon Motchane 80 | depuis déjà plusieurs années. Par exemple, moi j'ai trouvé une correspondance 81 | privée. Il a gagné la médaille Fields en 1966, Grothendieck. Il a refusé 82 | d'aller en russie pour chercher sa médaille, parce qu'il protestait contre 83 | l'emprisonnement de deux mathématiciens dans un asile psychiatrique. Donc on 84 | peut dire que à l'intérieur du monde mathématique, il avait quand même déjà une 85 | conscience politique. Motchane, qui tenait beaucoup aux honneurs pour son 86 | institut est allé à Moscou recevoir la médaille pour lui. Et quand il est 87 | revenu il tenait absolument à organiser à une cérémonie, où il décernerait, 88 | lui, la médaille à Grothendieck. Et Grothendieck, voulait rien savoir, disait 89 | "Donne moi ce truc, d'ailleurs je vais le donner au Vietnam." Il ne s'entendait 90 | pas du tout ces deux là. Le conflit était larvée, mais il était de plus en plus 91 | important et sur de plus en plus de sujets. Donc finalement c'était un prétexte 92 | cette histoire. C'était un prétexte aussi de la part de Motchane pour qu'il 93 | s'en aille. Parce que bien sûr Motchane aurait pu renoncer à ces quelques 94 | pourcentages de fonds militaires, mais il n'a pas voulu parce qu'ils ne se 95 | supportaient plus. 96 | 97 | G.D. --- Il faut savoir que Grothendieck n'aimait pas spécialement les prix et 98 | qu'il a reçu les plus belles distinctions en mathématiques mondiales. La 99 | médaille Fields, comme tu dis, qu'il a accepté, mais qu'il n'est même pas allé 100 | chercher et qu'il a donné à Hanoï effectivement. Et puis le prix Crafoord 101 | aussi, grande récompense mathématique, qu'il a refusé. Et donc après toutes ces 102 | aventures, il retourne à Montpellier, où il va être professeur. Mais il va 103 | avoir du mal finalement à noter ses élèves. Je crois qu'il n'aimait pas ça du 104 | tout. 105 | 106 | L.S. --- Oui. En fait je pense qu'il devait être un professeur extraordinaire. 107 | J'ai quelques écrits, une description du cours qu'il donnait une année. C'est 108 | incroyable, j'aurais tellement aimé être dans ses cours! Il découvrait beaucoup 109 | de choses qu'il n'avait jamais faites. Puisque les élèves avaient un petit 110 | niveau, il les faisaient découper avec du papier avec des ciseaux, faire des 111 | solides platoniciens, vraiment des choses concrètes. Et il découvrait lui même 112 | tout un aspect des maths qu'il n'avait jamais regardé. 113 | 114 | G.D. --- Ce qui est très étonnant c'est d'avoir eu cette composante pédagogique 115 | alors que lui-même refusait, notamment dans les *EGA* (*Éléments de Géométrie 116 | Algébrique*) de donner des exemples. C'était une pensée très abstraite, très 117 | difficile à aborder encore aujourd'hui, même pour des mathématiciens confirmé 118 | qui cherchent à dépouiller les archives. Et donc là, il a réussi. 119 | 120 | L.S. --- En fait c'est fascinant pour moi le refus des exemples de Grothendieck 121 | en tant que mathématicien. Il refusait tous ce qui était concret. Et quand je 122 | dis ça, c'est qu'une des raisons pour laquelle il est fascinant, c'est que sa 123 | vie ressemble à ses maths. Ce n'est pas quelque chose qu'on peut toujours dire. 124 | Dans ses maths et dans sa vie, tout est totalement épuré, tout est minimaliste. 125 | Il a besoin du concept le plus dépouillé. Dans sa maison il n'y avait rien, 126 | même pas de lit, il n'y avait rien. 127 | 128 | G.D. --- Oui c'était très spartiate. 129 | 130 | L.S. --- Complément spartiate! Et la maison elle-même, il vivait à 131 | Montpellier dans des petits villages, dans des maisons minuscules. Si vous 132 | voyez les photos, vous ne le croirez pas. Mais c'est ça qu'il voulait. Il 133 | aimait ça, sa maison était ouverte à n'importe quels gens de passages, qui 134 | pouvait venir, dormir. Mais on dormait sur un morceau de bois parce qu'il 135 | n'avait pas de lit. Je mets ça en lien direct avec son style en mathématiques 136 | qui était pareil. Qui était concentrée sur le besoin essentiel, les choses qui 137 | sont communes à de grande partie de maths, sans les détails et les 138 | particularités des personnalités de chacun. Je trouve il y a vraiment un esprit 139 | commun entre sa vie et ses maths. 140 | 141 | G.D. --- Et ça, ça atteint son paroxysme à partir de 1991. Alors là changement 142 | total, où il décide de vivre en acèse, comme un moine, à Lasserre, dans ce 143 | petit village de l'Ariège. Alors là, il a vraiment une vie très simple, il 144 | cultive son jardin, au sens propre, il passe beaucoup de temps avec ses 145 | plantes. 146 | 147 | L.S. --- Oui, parce que malgré tout quand il était à Montpellier donc, il avait 148 | de l'enseignement, il avait une maison, il avait des amis, finalement un 149 | cercle, pas mal de gens. Il faisait encore beaucoup de maths, qu'il ne publiait 150 | pas, mais qu'il mettait dans des caisses. 151 | 152 | G.D. --- Les fameuses archives de Montpellier. 153 | 154 | L.S. --- Les fameuses archives. Et il avait aussi une histoire amoureuse 155 | extrêmement passionnée, avec une dame qui habitait dans les environs. Mais à un 156 | moment donné, c'était de nouveau une vie qu'il ne voulait pas, il a voulu 157 | vraiment se couper de tout. 158 | 159 | G.D. --- Je crois que c'est Pierre Lechaq \[nom incertain\] qui me disait que 160 | ses passions c'était les maths, le bouddhisme et les femmes. 161 | 162 | L.S. --- Oui, enfin non, la méditation, mais c'est pas du boudhisme, c'est la 163 | méditation à sa façon. On peut dire c'est un peu Zen mais pas entièrement. 164 | C'est lui même qui disait que les trois passions de sa vie étaient les 165 | mathématiques, la méditation et les femmes. Et il faut dire que il y a beaucoup 166 | d'histoires qui sont plutôt belles parce que c'est un homme de passion, donc 167 | il faisait pas les choses légèrement, il ne laissait pas les gens indifférents. 168 | Ni homme ni femme d'ailleurs, que ce soit ses amis, ses élève, ses amantes, ses 169 | amies. 170 | 171 | G.D. --- J'aimerais te poser une question. Quand même c'est incroyable ce 172 | mathématicien qui a pris une ampleur considérable, qui était mondialement 173 | connu, qui a reçu les plus beaux prix des maths et qui va s'enfermer pendant 23 174 | ans dans un petit village. Il a pu parler encore à des gens, mais très peu, et 175 | puis à la fin de sa vie il ne parlait quasiment plus à personne. Je me souviens 176 | quand même que juste un mois avant sa mort en octobre 2014, il a invité ses 177 | enfants à dîner, et donc le mois d'après il décède à l'hôpital de Saint-Girons. 178 | Qu'est ce qui s'est passé? 179 | 180 | L.S. --- Alors il y a vraiment deux étapes. La première étape c'est en 1971, 181 | quand il quitte l'IHÉS, et où c'est vraiment mai 68 qui lui avait ouvert les 182 | yeux. Mais il ne supportait plus la vie qui n'était pas la sienne, c'était pas 183 | sa vie à lui. Lui c'était quand même un homme des pauvres, du village, de 184 | petites gens, qui pouvait parler avec des gens religieux, avec des moines 185 | bouddhistes. Et puis d'écologie, avec des gens qui faisait pousser leurs 186 | légumes dans leur jardin. Et tout d'un coup il a repris contact avec le 187 | concret. Que ce soit dans son enseignement, ou dans cette vie avec son jardin, 188 | alors qu'il s'était coupé du concret jusque là, jusqu'à l'âge 42 ans. Il a 189 | repris contact avec le concret, et il y a quand même quelques années pendant 190 | cette période qu'il appelle "le dimanche de ma vie". Je trouve que c'est une 191 | très belle expression. Il était heureux, et ce n'était pas un homme heureux en 192 | général, mais il a eu quelques années de bonheur. Mais ce qui s'est passé 193 | pendant les 18 ou 20 ans qu'il a passés à Montpellier, c'est que 194 | malheureusement il est rentré de nouveau dans des... Il a des tas de petites 195 | phrases très typique de sa façon parler, comme "le carrousel de l'amour". Tout 196 | va mal, il est en relation avec des gens qui ne le comprennent pas. Au début de 197 | cette période il a passé plusieurs années à vivre en communauté, et à 198 | travailler --- mais comme un dingue, parce que lui quand il faisait quelque 199 | chose c'était jusqu'au cou --- à l'écologie et à sortir un petit journal 200 | écologiste "Survivre et Vivre". Ce journal devait convaincre les gens de 201 | changer leur style de vie et de se rapprocher de la terre. Il a abandonné parce 202 | qu'il ne convainquait personne. Il n'était pas fait pour persuader, je me 203 | souvient de Pierre Cartier qui m'a dit une fois: "Il est venu à un congrès de 204 | maths pour parler d'écologie et convaincre les gens, mais il était énervant. À 205 | tel point, que j'étais d'accord avec tout ce qu'il disait, mais j'étais 206 | tellement énervé, que j'avais pas envie de faire ce qu'il disait, même si 207 | j'étais d'accord avec tout." Il se mettait les gens à dos, il n'était pas très 208 | doué pour convaincre, pour persuader. Donc il a renoncé à toute forme de 209 | prosélytisme ou de travail social. Et la communauté ça n'a pas marché bien sûr, 210 | parce que c'est dur de vivre en communauté. Je crois que c'est pas facile, et 211 | lui il avait besoin de solitude. Donc ça, ça a duré quelques années, après il a 212 | retrouvé sa solitude. Mais il avait quand même des élèves, des amis, une 213 | amante. 214 | 215 | G.D. --- Et alors il y a eu une deuxième rupture. 216 | 217 | L.S. --- C'est ça. À un moment donné, il n'a pas pu supporter le fait que rien 218 | ne marche. Rien, pas une relation humaine, pas une relation amoureuse, enfin il 219 | faut croire. La dame disait que c'était absolument merveilleux et que son 220 | départ était une terrible surprise pour elle. Mais peut-être qu'il souffrait 221 | quand même, que personne ne comprennait. Il m'a dit une fois: "J'ai 222 | l'impression d'être au large, et tous les gens, tout le monde, vous tous, vous 223 | êtes sur la rive. Et on peut pas communiquer, on peut juste se faire quelques 224 | signes." Je crois qu'il voulait être seul, qu'il n'en pouvait plus de ces 225 | communications qui ne marchaient pas. Et il a décidé, sans rien dire à 226 | personne, de disparaître complètement. Il a attendu que son amie soit partie en 227 | week-end, puis il a brûlé des milliers et des milliers de pages. Il avait comme 228 | une espèce de vieille baignoire dans le jardin, qu'il a rempli de papiers, et 229 | il a tout brûlé, elle n'a trouvé que des tas de cendres. Mais il a quand même 230 | laissé plusieurs caisses de maths, et d'autres trucs dans sa petite maison. Il 231 | lui a laissé un mot: "Tout ce que je laisse dans la maison tu peux t'en 232 | occuper, tu peux le garder." Et c'est tout, elle ne savait pas où il était 233 | allé, personne ne le savait. Il a complètement disparu corps et âme. Ça c'était 234 | en 1991, juste au moment où moi je suis tombé sur le manuscrit \[d'*Esquisse 235 | d'un Programme*\]. Et puis il avait écrit beaucoup d'autres choses que j'ai 236 | commencé à lire petit à petit. Il avait écrit un livre immense, très beau, qui 237 | s'appelle *Récoltes et Semailles* sur sa vie personelle et sa vie mathématique. 238 | 239 | G.D. --- C'est parfait parce que justement, j'ai ici un chapitre imprimé de 240 | *Récoltes et Semailles*, qu'il a donc écrit à la fin de sa vie. 241 | 242 | L.S. --- Pas à la fin de sa vie, il l'a écrit en 1983--84 je pense. 243 | 244 | G.D. --- Bon, quand même relativement tardivement. 245 | 246 | L.S. --- Il a soixante ans. La fin de la vie --- moi je les ai dans quelques 247 | jours, les soixantes ans. 248 | 249 | G.D. --- D'accord, d'accord! Par rapport à la solitude que tu évoquais, je 250 | voulais dire que c'est une solitude qui est doublée d'une très haute opinion de 251 | lui-même. Il y a un passage qui m'a toujours fait rire, je n'avais pas prévu de 252 | le lire, mais je le trouve quand même assez incroyable. *Récoltes et Semailles* 253 | c'est une immense oeuvre dans laquelle il parle à la fois de sa vie, de sa 254 | philosophie, et de ses mathématiques. Et donc là il parle de ses mathématiques 255 | et il dit: 256 | 257 | > La chose qui m'a frappé c'est que je ne me rappelle pas avoir eu connaissance 258 | > ne fût-ce que par allusion par des amis ou collègues mieux versés en histoire 259 | > que moi, d'un mathématicien à part moi qui ait apporté une multiplicité 260 | > d'idées novatrices, non pas plus ou moins disjointes les unes des autres, 261 | > mais comme parties d'une vaste vision unificatrice (comme cela a été le cas 262 | > pour Newton et pour Einstein en physique et en cosmologie \[...\]). J'ai eu 263 | > connaissance seulement de deux "moments" dans l'histoire de la mathématique, 264 | > où soit née une vision nouvelle de vaste envergure. 265 | 266 | Puis il parle de la grèce antique et du moment Descartes, Newton, Leibniz, je 267 | passe. 268 | 269 | > Pour autant que je sache, la vision née en l'un ou en l'autre moment a été 270 | > l'oeuvre non d'un seul, mais l'oeuvre collective d'une époque. 271 | 272 | Donc non seulement j'ai révolutionné les maths, mais en plus je les ai 273 | révolutionnées tout seul! Je trouve que c'est quand même un passage assez 274 | éloquent. Donc ça, c'est dans *Récoltes et Semailles*, qui va être publiés le 275 | mois prochain, n'est-ce pas? 276 | 277 | L.S. --- Oui, voilà. Donc finalement ce livre qui n'avait jamais été publié, 278 | pour une longue multiplicité de raisons compliquées, ayant à voir d'abord avec 279 | lui et ensuite avec ses héritiers, va être publié. Il va sortir en janvier chez 280 | Gallimard. Moi je trouve que c'est un livre magnifique. C'est très long, c'est 281 | très beau, apparemment ils n'ont pas fait de coupe du tout. Il ya des parties 282 | qui parlent de sa vie, de ses pensées sur lui-même, qui peuvent être vraiment 283 | lues par n'importe qui, et d'autres parties plus mathématiques. Mais je tients 284 | quand même à répondre à ce que tu as dit là. Il avait une très haute et belle 285 | opinion de ses propres mathématiques, qu'il trouvait magnifiques, il le dit à 286 | plusieurs reprises. Mais il a simplement raison! Et si Einstein disait que la 287 | relativité est une découverte incroyable, unique dans l'histoire de la 288 | physique, il aurait raison! Et il n'avait pas une si haute opinion de lui-même 289 | en tant qu'individu. Il se critique même sévèrement à plusieurs moments, et il 290 | tente de parler de lui-même avec une grande honnêtetée. Bon, chacun sait que 291 | c'est pas toujours facile d'aller jusqu'au bout, mais il essaye vraiment. Mais 292 | les mathématiques, le corpus de mathématiques qu'il avait fait, oui, il 293 | l'aimait d'amour. 294 | 295 | "Le génie Grothendieck raconté par Leïla Schneps", Sabre Bougrine, Gauthier 296 | Depambour et Leïla Schneps.

Il le dit lui-même, il dit 33 | "J'ai stagné complètement pendant tout le temps que je faisais des maths, parce 34 | que je faisait que des maths." 35 | 36 | Il y a Michel Demazure, un de ses élèves qui est devenu un excellent 37 | mathématicien, qui raconte cette anecdote, où un jour, il a croisé Grothendieck 38 | dans la rue qui lui disait "Tu vas où?" Et il disait je sais pas "je vais au 39 | concert" ou au cinéma ou quelque chose comme ça. "Pourquoi tu fais pas des 40 | maths? Pourquoi tu fais autre chose?" Et une dixaine d'années plus tard, donc 41 | après la grande rupture et tout, il l'a recroisé dans la rue, il a dit 42 | "Qu'est-ce que tu fais ses jours-ci?" Et Démazure répond: "J'essaie de 43 | démontrer machin truc." "Tu fais encore des maths?!" Donc c'était tout ou rien 44 | avec Grothendieck, voilà c'était tout ou rien. Donc je sais pas ce qu'il 45 | pensait politiquement ni écologiquement avant 68. Ce que je sais c'est que 46 | c'était énorme pour lui cette révolution étudiante. Qu'il se sentait 47 | complètement, 100% avec les étudiants, du côté des étudiants. Et qu'il essayait 48 | de leur dire, il a essayé de communiquer, il a essayé de faire des, comment 49 | dire, des communications. Et que les étudiants en gros lui disait "Mais vous 50 | êtes un des mandarins, vous êtes précisément de ceux contre qui on se bat." Et 51 | pour lui c'était terrible. Tout d'un coup il s'est vu avec les yeux des autres. 52 | Et il n'a pas voulu ça. Et ça, mai 68, était le début de ce mouvement qui a 53 | fini avec la rupture en 70--71. Donc à partir de ce moment là on peut dire 54 | qu'il a ouvert les yeux, il se dit "Je suis en train de tuer la personne que je 55 | suis vraiment, d'écraser." Et il a parlé plus tard dans un autre contexte, très 56 | souvent d'"enterrement", "enterrement", on y arrivera peut-être. Mais je pense 57 | qu'il savait ce que ça voulait dire, parce que c'est quelque chose qu'il avait 58 | fait à lui-même pendant de longues années. 59 | 60 | G.D. --- Justement cette rupture dont tu parles des années 70--71 provient du 61 | fait, aussi, qu'il était anti-militariste, enfin qu'il est devenu en tout cas, 62 | très anti-militariste et qu'il ya eu une petite proportion, toute petite --- je 63 | crois que c'était 5% du budget de l'IHÉS --- qui provenaient de fonds 64 | militaires. Il a essayé de se battre pour que ce budget, ces 5% là soient 65 | abandonnées, et comme ça n'a pas été abandonné il a claqué la porte de l'IHÉS. 66 | 67 | L.S. --- Oui, en fait... 68 | 69 | G.D. --- Alors, peut-être je raconte juste la rupture dans sa totalité. Il est 70 | allé au Collège de France, on lui a trouvé une place au Collège de France, et 71 | là il a commencé aussi à faire des cours, en expliquant... que les maths... ça 72 | servait peut-être pas à grand chose. Enfin il a essayé de politiser ses cours, 73 | et ça n'a pas plu non plus aux professeurs du Collège de France, et il a été 74 | viré du Collège de France. Et donc c'est après, je crois qu'il a fait un an à 75 | Orsay et il est revenue finalement à Montpellier, où il avait fait ses années 76 | de licence. 77 | 78 | L.S. --- Oui je tiens quand même à dire que tout est exactement comme tu l'a 79 | raconté, à ceci près que les fonds militaires que recevait l'IHÉS c'était un 80 | prétexte. Il y avait un conflit larvé avec le directeur de l'IHÉS Léon Motchane 81 | depuis déjà plusieurs années. Par exemple, moi j'ai trouvé une correspondance 82 | privée. Il a gagné la médaille fields en 66, Grothendieck. Il a refusé d'aller 83 | en Russie pour chercher sa médaille, parce qu'il protestait contre 84 | l'emprisonnement de deux mathématiciens qui avaient été en fait enfermés dans 85 | un asile psychiatrique. Donc on peut dire que à l'intérieur des maths, il avait 86 | quand même déjà une conscience politique, à l'intérieur du monde mathématiques. 87 | Donc Motchane qui tenait beaucoup aux honneurs pour son institut, est allé à 88 | Moscou recevoir la médaille pour lui. Et quand il est revenu il voulait 89 | absolument organiser à une cérémonie, où il décernerait, lui, la médaille à 90 | Grothendieck. Et Grothendieck, rien du tout "Donne moi ce truc d'ailleurs je 91 | vais le donner au Vietnam." Bon, bref, et il s'entendait pas du tout ces deux 92 | là, pas du tout du tout. Et le conflit était larvée, mais était de plus en plus 93 | important et de plus en plus profond sur de plus en plus de ce sujet, de 94 | raisons différentes. Et donc finalement c'était un prétexte cette histoire. 95 | C'était un prétexte aussi de la part de Motchane pour qu'il s'en aille. Parce 96 | que bien sûr Motchane aurait pu, comment dire, renoncer, à ces quelques 97 | pourcentages de fonds militaires, mais il n'a pas voulu parce qu'il supportait 98 | plus et ça marchait plus quoi. 99 | 100 | G.D. --- Il faut savoir, tu en parlais, que Grothendieck n'aimait pas 101 | spécialement les prix et il a reçu les plus belles distinctions en 102 | mathématiques mondiales. La médaille Fields, comme tu dis, qu'il a accepté, 103 | mais qu'il n'est même pas allé chercher. 104 | 105 | L.S. --- Je plaisante pas il l'a donné au Vietnam pour... 106 | 107 | G.D. --- Il l'a donné à Hanoï effectivement. Et effectivement et puis le prix 108 | Crafoord aussi, grande récompense mathématique, qu'il a refusé, donc... Et donc 109 | après toutes ces aventures il retourne à Montpellier où bon, il va être 110 | professeur, mais il va avoir du mal finalement à noter ses élèves. Je crois 111 | qu'il n'aimait pas du tout. 112 | 113 | L.S. --- Oui, en fait moi je pense qu'il devait être un professeur 114 | extraordinaire. Il écrit, j'ai quelques écrits, j'ai une description du cours 115 | qu'il donnait une année. C'est incroyable, c'est... Moi j'aurais tellement aimé 116 | être dans ses cours je pense! Il découvrait beaucoup de choses qu'il avait 117 | jamais fait, puisque les élèves avaient un petit niveau, donc il les faisaient 118 | découper avec des ciseaux, du papier, faire des solides platoniciens, vraiment 119 | des choses concrètes. Et il découvrait lui même tout un aspect des maths qu'il 120 | n'avait jamais regardé. 121 | 122 | G.D. --- Ce qui est très étonnant d'avoir eu cette composante pédagogique alors 123 | que lui-même refusait, notamment dans les EGA, les Éléments de Géométrie 124 | Algébrique, de donner des exemples. C'était une pensée très très abstraite, 125 | très difficile encore aujourd'hui à aborder même pour des mathématiciens 126 | confirmé qui cherchent à dépouiller les archives. Et donc là, il a réussi. 127 | 128 | L.S. --- En fait c'est fascinant pour moi le refus de Grothendieck en tant que 129 | mathématicien, le refus des exemple. Il refusait tous ce qui était concret. Et 130 | quand je dis ça, pour moi, pourquoi il est fascinant, une des raisons pourquoi 131 | il est fascinant, c'est que sa vie ressemble à ses maths. C'est pas quelque 132 | chose qu'on peut toujours dire. Dans ses maths et dans sa vie, tout est 133 | totalement épuré, tout est minimaliste. Il a besoin uniquement du concept le 134 | plus dépouillé en fait. Alors dans sa maison il n'y avait rien, même pas de 135 | lit, il n'y avait rien. 136 | 137 | G.D. --- Oui c'était très spartiate. 138 | 139 | L.S. --- Complément spartiate! Et la maison elle-même, il vivait à 140 | Montpellier dans des petits villages, dans des maisons minuscules. Si vous 141 | voyez les photos, on n'arrive même pas à le croire. Mais c'est ça qu'il 142 | voulait. Il aimait ça, sa maison était ouverte à --- n'importe qui pouvait 143 | venir, des gens de passage, dormir. Mais on dormait sur un morceau de bois 144 | parce qu'il n'avait pas de lit. Et pour moi, je mets ça en lien direct avec son 145 | style en mathématiques qui était pareil. Qui était juste le besoin essentiel, 146 | les choses qui sont communes à de grandes parties de maths, sans les détails et 147 | les particularités des personnalités de chacun. Je trouve il y a vraiment un 148 | esprit commun entre sa vie et ses maths. 149 | 150 | G.D. --- Et ça, ça atteint son paroxysme à partir de 1991. Alors là changement 151 | total, où il décide de vivre en acèse, comme un moine, à Lasserre, dans ce 152 | petit village de l'Ariège, c'est ça? 153 | 154 | L.S. --- Oui. 155 | 156 | G.D. --- Alors là vraiment, une vie très très simple, il cultive son jardin, au 157 | sens propre, il passe beaucoup de temps avec ses plantes. 158 | 159 | L.S. --- Oui, parce que malgré tout quand il était à Montpellier, donc il avait 160 | de l'enseignement, il avait une maison, il avait des amis, finalement un 161 | cercle, pas mal de gens. Il faisait encore des maths, qu'il publiait pas, mais 162 | beaucoup beaucoup de maths qu'il mettait dans des caisses. 163 | 164 | G.D. --- Les fameuses archives de Montpellier. 165 | 166 | L.S. --- Les fameuses archives. Et il avait aussi une histoire amoureuse 167 | extrêmement passionnée, avec une dame qui habitait dans les environs. Et à un 168 | moment donné, c'était de nouveau une vie qu'il ne voulait pas. Il voulait 169 | vraiment se couper de tous. 170 | 171 | G.D. --- Je me demande, je crois que c'est Pierre Lechaq \[nom incertain\] qui 172 | me disait, ses passions c'était les maths, le bouddhisme et les femmes. 173 | 174 | L.S. --- Oui, enfin non, la méditation mais c'est pas du boudhisme, c'est la 175 | méditation à sa façon. On peut dire c'est un peu Zen mais... C'est lui qui dit! 176 | C'est lui même il a dit "les mathématiques, la méditation et les femmes", trois 177 | passion de sa vie. Et il faut dire que il y a beaucoup beaucoup d'histoires qui 178 | sont plutôt belles parce que c'est un homme de passion, donc il faisait pas 179 | les choses légèrement, il laissait pas les gens indifférents. Ni homme ni femme 180 | d'ailleurs, que ce soit ses amis, ses l'élève, ses amantes, ses amies. 181 | 182 | G.D. --- Et moi j'aimerais te poser une question. Quand même c'est incroyable 183 | ce mathématicien qui a pris une ampleur considérable, qui était mondialement 184 | connu, qui a reçu les plus beaux prix des maths, qui va s'enfermer pendant 23 185 | ans dans un petit village. Il a pu parler encore à des gens mais très très peu 186 | et puis à la fin de sa vie il parlait quasiment à plus personne. Je me souviens 187 | quand même que juste un mois avant sa mort en octobre 2014, il a invité ses 188 | enfants à dîner, et donc le mois d'après il décède. À l'hôpital de 189 | Saint-Girons. Qu'est ce qui s'est passé? 190 | 191 | L.S. --- Alors il y a vraiment deux étapes. Donc la première étape c'est en 71 192 | quand il quitte l'IHÉS, où c'est vraiment mai 68 qui lui avait ouvert les yeux. 193 | Mais il supportait plus la vie qui n'était pas la sienne, c'était pas sa vie à 194 | lui. Lui c'était quand même un homme des pauvres, du village, de gens, de 195 | petits, qui pouvait parler avec des gens religieux, avec des moines 196 | bouddhistes. Et puis l'écologie, avec des gens qui faisait pousser leurs 197 | légumes dans leur jardin. Et tout d'un coup il a repris contact avec le 198 | concrêt. Que ce soit dans son enseignement ou dans cette vie avec son jardin, 199 | il s'était coupé du concret jusque là, jusqu'à l'âde 42 ans. Il a repris 200 | contact avec le concrêt, et il y a quand même quelques années pendant cette 201 | période qu'il appelle "le dimanche de ma vie", que je trouve une très belle 202 | expression. Il était heureux et c'était pas un homme heureux en général, il y a 203 | eu quelques années de bonheur. Mais qu'est ce qui s'est passé pendant les 18 ou 204 | 20 ans qu'il a passés à Montpellier, c'est que malheureusement il est rentré de 205 | nouveau dans des... il a des tas de petites phrases très typique de sa façon 206 | parler: "le carrousel de l'amour" où ça va toujours mal c'est jamais bien, les 207 | relations avec les gens, mais qui vous comprennent pas. Et il avait passé, tu 208 | en a parlé tout à l'heure, au début de cette période il a passé plusieurs 209 | années à vivre en communauté, et à travailler --- mais comme un dingue, parce 210 | que lui quand il faisait quelque chose c'est jusqu'au cou --- à l'écologie et à 211 | sortir un petit journal écologiste *Survivre et Vivre* qui devait convaincre 212 | les gens maintenant de changer leur style de vie et se rapprocher de la terre. 213 | Il a abandonné parce qu'il ne convainquait personne. Il n'était pas fait pour 214 | persuader, je me souvient de Pierre Cartier qui m'a dit une fois: "Il est venu 215 | à un congrès de maths pour parler d'écologie et convaincre les gens, et Cartier 216 | a dit, il était énervant, à tel point que moi j'étais d'accord avec tout ce 217 | qu'il disait, mais j'étais tellement énervé que j'avais pas envie de faire ce 218 | qu'il disait, même si j'étais d'accord avec tout." Il se mettait les gens à dos 219 | en fait, il n'était pas très doué comme ça, pour convaincre, pour persuader. 220 | Donc il a renoncé à toute forme de prosélytisme, ou de travail social. Et la 221 | communauté ça n'a pas marché bien sûr, parce que c'est dur de vivre en 222 | communauté, je crois que c'est pas facile, et lui il avait besoin de solitude. 223 | Donc ça, ça a duré quelques années, après il a retrouvé sa solitude, mais 224 | c'était pas de la solitude. Il avait quand même des élèves, des amis, une 225 | amante, bon. 226 | 227 | G.D. --- Alors il a eu une deuxième rupture. 228 | 229 | L.S. --- C'est ça, c'est ça. À un moment donné, il n'a pas pu supporter le fait 230 | que rien ne marche. Rien, pas une relation humaine, pas une relation amoureuse, 231 | enfin il faut croire, je sais pas, la dame disait que c'était absolument 232 | merveilleux et que son départ était une terrible surprise pour elle. Mais lui, 233 | peut-être il y avait de la souffrance quand même. Il s'est dit personne 234 | comprend. Il m'a dit une fois: "J'ai l'impression d'être au large et tous les 235 | gens, tout le monde, vous tous, vous êtes sur la rive. Et on peut pas 236 | communiquer, pas vraiment, on peut faire ça \[fait un signe de la main\]." Je 237 | crois que il s'est dit: "Je veux être seul, j'en peux plus. J'en peux plus de 238 | ces communications qui ne marchent pas." Et il a décidé, sans dire à personne, 239 | de disparaître, complètement. Et donc il a vraiment attendu que son amie soit 240 | partie en week-end, il a brûlé des milliers, des milliers et des milliers de 241 | pages. Elle a trouvé --- il avait comme une espèce de vieille baignoire dans le 242 | jardin, qu'il a rempli de papier, il a tout brûlé. Donc elle a trouvé juste des 243 | piles de cendres. Mais il a laissé plusieurs caisses de maths, et d'autres 244 | trucs dans sa petite maison quand même. Et il lui a laissé un mot: "Tout ce que 245 | je laisse dans la maison tu peux t'en occuper, tu peux garder." Et c'est tout, 246 | elle savait pas où il était allé, personne ne savait où il était allé. Il a 247 | disparu corps et âme, complètement. Ça c'était en 1991, juste au moment où moi 248 | je suis tombé sur le manuscrit. Et puis il avait écrit beaucoup d'autres choses 249 | que j'ai commencé à lire petit à petit. Il avait écrit un livre immense, très 250 | beau qui s'appelle *Récoltes et Semailles* sur sa vie et sa vie mathématique. 251 | 252 | G.D. --- Alors c'est parfait parce que justement, j'ai un chapitre imprimé ici 253 | de *Récoltes et Semailles* donc qu'il a écrit à la fin de sa vie. 254 | 255 | L.S. --- Pas à la fin de sa vie, en 83--84 il l'a écrit je pense. 256 | 257 | G.D. --- Bon quand même relativement tardivement. 258 | 259 | L.S. --- Il a soixante ans, la fin de la vie, moi je les ai dans quelques 260 | jours, les soixantes ans. 261 | 262 | G.D. --- D'accord, d'accord, c'est bon! Non, je voulais dire, par rapport à la 263 | solitude que tu évoquais, c'est une solitude qui est doublée d'une très haute 264 | opinion de lui-même. Et il y a un passage qui m'a toujours fait rire, je vous 265 | le lis, j'avais pas prévu de le lire, mais je le trouve quand même assez 266 | incroyable. Donc *Récoltes et Semailles* c'est une immense oeuvre dans laquelle 267 | il parle à la fois de sa vie, de sa philosophie, et de ses mathématiques et 268 | donc là il parle de ses mathématiques et il dit: 269 | 270 | > La chose qui m'a frappé c'est que je ne me rappelle pas avoir eu connaissance 271 | > ne fût-ce que par allusion par des amis ou collègues mieux versés en histoire 272 | > que moi, d'un mathématicien à part moi qui ait apporté une multiplicité 273 | > d'idées novatrices, non pas plus ou moins disjointes les unes des autres, 274 | > mais comme parties d'une vaste vision unificatrice \[on va en reparler\] 275 | > (comme cela a été le cas pour Newton et pour Einstein en physique et en 276 | > cosmologie \[...\]). J'ai eu connaissance seulement de deux "moments" dans 277 | > l'histoire de la mathématique, où soit née une vision nouvelle de vaste 278 | > envergure. 279 | 280 | Donc il parle de la grèce antique et puis du moment Descartes, Newton, Leibniz, 281 | bon je passe. 282 | 283 | > Pour autant que je sache, la vision née en l'un ou en l'autre moment a été 284 | > l'oeuvre non d'un seul, mais l'oeuvre collective d'une époque. 285 | 286 | Donc non seulement j'ai révolutionné les maths, mais en plus je les ai 287 | révolutionnées tout seul! Je trouve que c'est quand même un passage assez 288 | éloquent. Donc ça c'est dans *Récoltes et Semailles*, dont on va parler. 289 | 290 | Sabre Bougrine --- Qui a jamais été publié? 291 | 292 | G.D. --- Alors, on peut peut-être en parler maintenant? *Récoltes et Semailles* 293 | qui va être publiés le mois prochain, n'est-ce pas. 294 | 295 | L.S. --- Oui, voilà. Donc finalement le livre qui n'avait jamais été publié, 296 | pour une longue multiplicité de raisons compliquées, ayant à voir d'abord avec 297 | lui et ensuite avec ses héritiers, va être publié, va sortir en janvier chez 298 | Gallimard. Moi je trouve que c'est un livre magnifique. C'est très long, c'est 299 | très beau, apparemment ils ont pas fait de coupe du tout. Et il ya des parties 300 | qui parlent de sa vie qui parlent de ses pensées sur lui-même qui peuvent être 301 | vraiment lues par n'importe qui, et d'autres parties plus mathématiques. Mais 302 | je tiens quand même à répondre à ce que tu as dit là. Il avait une très haute 303 | et belle opinions de ses propres mathématiques, qu'il trouvait magnifiques, il 304 | le dit à plusieurs reprises. Mais il a juste raison! Et si Einstein disait 305 | relativité est une découverte incroyable, unique dans l'histoire de la 306 | physique, il a juste raison! Et il n'avait pas une haute opinion de lui-même 307 | comme homme ou individus. Il se critique même sévèrement à plusieurs moments, 308 | et il tente de parler de lui-même avec une grande honnêtetée. Bon chacun sait 309 | que c'est pas toujours facile d'aller jusqu'au bout. Mais il essaye vraiment. 310 | Mais les mathématiques, le corpus de mathématiques qu'il avait fait, oui, il 311 | l'aimait d'amour. 312 | --------------------------------------------------------------------------------
