Significantly, this book is not called From Brain to Computer. Lytton argues in exactly the opposite direction from Peter beim Graben and James Wright, whose plaintive statement is worth quoting again: “Sadly, we do not know which physical properties are truly essential.” How does one know that the neuronal “complexities,” which are being so “aggressively pared” away, aren’t important? Much remains to be understood about the brain. Why must biological subtleties be “cut through”? Who is the judge of “irrelevant detail” and how does one know that an “essence” is revealed and not a convenient fiction forced into a now classical computational box? An example from genetics may be valuable. Many people have heard of “junk DNA,” DNA that was faithfully copied over generations but had no apparent purpose, hence the derogatory name. Geneticists now know that it does in fact have a purpose. It is not “junk” at all.278
Flesh-and-blood human beings are wet, not dry creatures. It seems clear to me that Richard Dawkins’s “throbbing gels and oozes” are meant to stand in for a wet, living embryo or for a whole biological, material body. Dawkins’s phrase eschews wetness and the immense complexity of embryology, which he plainly states he would rather not “contemplate.” Computational theory of mind, with its concept neurons and its notion of the “mental” as an information-processing machine that may be considered independently of brain function, mechanizes and “dries” the mind into comprehensible algorithms. I am using the word “wet” to signal not just the watery human brain or the moistness of corporeal reality but also as a guiding metaphor that may take us further toward the fears and wishes that hide beneath CTM.
We human animals ingest the world in many ways, when we eat and chew and breathe. We take in the world with our eyes, ears, and noses, and we taste it with our tongues and experience its textures on our skin. We urinate and defecate and vomit and cry tears, and we spit and sweat and menstruate, make milk and sperm, leak vaginal fluids and snot. Our skin forms a boundary around each of us, but that too is porous and can be punctured. We kiss and penetrate one another in various erotic ways, and we copulate, and some forms of corporeal entanglements produce children. And when a woman gives birth, she pushes the infant out of her body. The newborn baby arrives in the world covered in blood and fluids. The placenta, the afterbirth, oozes out of the mother’s vagina. And we die. Our organic bodies putrefy and disintegrate, and we disappear from the world. Are these natural processes separable from our thoughts and our words? That is the question. Turing wanted to include development in his idea of making a machine mind. Embryology fascinated him, and he proposed the infant mind as a machine to be trained and shaped, but “wetness” was never part of the equation. Wasn’t Turing right in saying that this model left out sex and food and sport and much that we value in our lives? Isn’t this a problem?
Biological realities of human development play no role in computational theory of mind except as an inferior gelatinous substrate or annoying complexities to be cut through so a conceptual essence can be revealed. The leaky, moist, material body is not part of its model of mind. The embryo, the growing or the grown-up body that throbs and oozes, has nothing to do with intelligence or the mind advocates of GOFAI hoped to build—a smart, clean, man machine. The computer has inputs and outputs, a restricted entryway and exit. The fantasy of the Replicant or Replicator is clearly alive in David Deutsch’s idea of “Analytical Enginekind,” an alternative being, which may be made of other stuff, but to suppose any inferiority in such a “kind” amounts to “racism.”
Doesn’t this theory harbor a wish for a beautiful, dry, thinking machine, a new race that will not grow in or be born from the organic maternal body or from organic materials at all: no wimpy dependent genes, no mother’s egg, no father’s sperm, no embryo, no placenta, no uterine environment, no birth by pushing one person out of another, but rather a new kind of person made from cogs and wheels or digital ones and zeros? All matter, all gels and oozes, will be avoided. Jonathan Swift’s satirical poem “The Lady’s Dressing Room” springs to mind with its immortal line, “Oh! Celia, Celia, Celia shits!” The same poem contains this couplet: “Should I the Queen of Love refuse / Because she rose from stinking ooze?”279 The new race will be born straight out of scientists’ computational minds or discovered somewhere else in the universe. The story of wet, organic, mammalian development is suppressed. There is no beginning and no end, no birth and no death because the new race will be immortal.
A leap back to the seventeenth century is in order. When Bernard de Fontenelle (1657–1757) was confronted with Descartes’s idea of the animal as machine, he had a witty rejoinder: “Do you say that Beasts are Machines just as Watches are? Put a Male Dog Machine and a Bitch Machine side by side, and eventually a third little Machine will be the result, whereas two Watches will lie side by side all their lives without ever producing a third Watch.”280 Watches still can’t propagate. Kismet will never grow up and choose to or accidentally become a parent.
What is going on here? Why are the complexities of actual biological neurons regarded as so much irrelevant detail? Even if, let us say, information (defined in one way or another) trumps biology, wouldn’t actual neurons still be crucial to understanding how the whole business works? Are these cells inferior because they die? Is this a rejection of the mortal body for a better model? In the Western tradition, hasn’t woman always been understood as more body and less reflection than man? Isn’t this still the case? Doesn’t the young, beautiful, voluptuous woman who reveals herself to be a formidable intellectual continue to create surprise and amazement? Do people harbor the same prejudices when the young, beautiful intellectual is a man? In his essay on medieval misogyny, R. Howard Bloch notes the same division I discussed in relation to Aristotle in Saint Augustine’s thought: “Herein lies one possibility of reading misogyny: if man enjoys existence (substance), being, unity, form, and soul, woman is associated with accident, becoming (temporality), difference, body, and matter . . . That is, man is form or mind, and woman, degraded image of his second nature, is relegated to the realm of matter.”281 Information is the pattern, the immaterial essence, which can be beamed here and there. It is the computing mind of Descartes. It is pure and untouched by sordid matter, those natural gels and oozes that threaten it with contamination and the forces of time.
I have returned to Purity and Danger: An Analysis of Concepts of Pollution and Taboo, written by the social anthropologist Mary Douglas, over and over since I first read the book as a graduate student. In her introduction, Douglas writes, “Reflection on dirt involves the reflection on the relation of order to disorder, being to non-being, form to formlessness, life to death.”282 Douglas’s argument is that pollution appears when the boundaries of any structure, form, or body are threatened—in the murky not-one-not-the-other places. Therefore all transitional blurry states are risky, including the stuff that leaks across corporeal boundaries.
Any structure of ideas is vulnerable at its margins. We should expect the orifices of the body to symbolize its specially vulnerable points. Matter issuing from them is marginal stuff of the most obvious kind. Spittle, blood, milk, urine, faeces or tears by simply issuing forth have traversed the boundary of the body. So also have bodily pairings [sic], skin, nail, hair clippings and sweat. The mistake is to treat bodily margins in isolation from all other margins.283
As Douglas points out, pollutants vary depending on culture. In some cultures, menstrual blood is toxic; in others, excreta or saliva are to be shunned. Rituals surrounding reproduction and birth in every society are significant because one body enters another in heterosexual intercourse, an embryo is created, and one body emerges from the body of another in birth. All mingling bodies are potentially impure and dangerous. If, however, a man can be disembodied, translated, and reproduced as information, all pollution concerns are eliminated. The man literally dematerializes.
One evening over dinner, I was describing this concept of information to my sister, the scholar and writer
Asti Hustvedt. She looked at me and said, “It’s the soul.” Indeed, it is—the soul for a new age. The ancient belief in the soul with its attendant fears of the pollutions of the body, the senses, and desire, which influenced Pauline Christianity and were reconfigured in Cartesian philosophy, remain with us. After the body has withered, the immortal, rational, computational soul remains.
Phantasy Land in Its Sincere and Ironic Modes
The idea that immortality is just around the bend via machine intelligence has been avidly promoted by Ray Kurzweil, scientist, inventor, and best-selling author, a person repeatedly described as a “genius” in the popular press and the subject of a documentary fittingly titled Transcendent Man. Kurzweil’s book The Singularity Is Near: When Humans Transcend Biology was something of a sensation. “The singularity,” although used in physics, is a term first coined for technology by the mathematician Vernor Vinge in 1983. According to Kurzweil, the singularity will arrive in 2045. There will be an intelligence explosion. Human beings and computers will merge. The jacket copy for The Singularity Is Near tells the reader that we humans are poised for a revolution “as our species breaks the shackles of its genetic legacy and achieves inconceivable heights of intelligence, material progress, and longevity.”284 The admittedly eclectic Journal of Consciousness Studies has dedicated two entire issues to the singularity and has published not only Kurzweil but other thinkers who are eagerly anticipating the imminent transformation when we will be freed from our mortal bodies, a science or science fiction version of what fundamentalist Christians call “the rapture.” David Chalmers, an analytical philosopher, wondered in an essay why the singularity had not created more interest among “philosophers, academic scholars, cognitive scientists and artificial intelligence researchers.”285 The rhetorical tone of its proponents may be one reason some thoughtful persons have chosen not to “go there.”
Some believe that although biological reproduction and birth will disappear after the singularity, sex will remain, and according to one of its boosters, it will be bigger and better, enhanced and freed by technology. All impediments to ecstasy will be eliminated. David Pearce in his Internet essay The Hedonistic Imperative (1995) writes:
Erotic pleasure of an intoxicating intensity that mortal flesh has never known will thereafter be enjoyable with a whole gamut of friends and lovers. This will be possible because jealousy, already transiently eliminable today under the influence of various serotonin-releasing agents, is not the sort of gene-inspired perversion of consciousness to be judged worthy of conservation in the new era.286
Serotonin was a high-fashion neurochemical in the midnineties when the essay was written; its role as a panacea has diminished significantly since then. SSRIs, the miracle antidepressants of that moment, have lost their otherworldly glow. Whether or not their placebo effect is what made drugs such as Prozac successful, there is no scientific evidence that low serotonin levels cause depression.287 What seems certain is that the reputation of these drugs as cure-alls is over. Jealousy is an emotion that involves strong attachment to another person and the desire to have that person all for one’s own. Surely, it grows out of our earliest attachment and love for our mothers and fathers or important caretakers. I vividly remember my own infant daughter playing peacefully by herself at my feet when she was not yet one year old. The moment I picked up the phone to make a call, however, her mood turned, and I had a whining, protesting little person clinging to my legs. Pearce and his colleagues hope to rid us of this annoying “gene-inspired” feature of our emotional repertoire. In fact, in this techno paradise of no jealousy and perpetual orgasm, all sexual suffering will vanish. I offer a film title as illustrative of the hidden fantasy: Revenge of the Nerds.
Hans Moravec, an important AI scientist, is another figure who became interested in embodied models for robots. The idea named after him, Moravec’s paradox, articulates the irony that what is hard for human beings—performing an elaborate mathematical calculation, for example—is a snap for a machine. What machines can’t do well is to perform highly sensitive motor-sensory tasks: snagging a piece of lint with one’s fingernails and flicking it away, for example. Dreyfus saw this problem early on when he wrote about “know-how.” Moravec is an interesting character because, despite his embrace of the importance of motor-sensory systems in artificial intelligence, he clings to an informational model of the mind that anticipates the end of that pesky impediment to immortal life, the human body. His science is also science fiction.
In his prologue to Mind Children: The Future of Robot and Human Intelligence, published in 1988, a book written for a popular audience, the scientist looks forward to a future that is “best described as ‘post biological’ or even ‘supernatural.’
It is a world in which the human race has been swept away by the tide of cultural change, usurped by its own artificial progeny. The ultimate consequences are unknown, though many intermediate steps are not only predictable but have already been taken. Today our machines are still simple creations, requiring the parental care and hovering attention of any newborn, hardly worthy of the name intelligent. But within the next century they will mature into entities as complex as ourselves, and eventually into something transcending everything we know—in whom we can take pride when they refer to themselves as our descendants. Unleashed from the plodding pace of biological evolution the children of our minds will be free to grow to confront the immense and fundamental challenges in the larger universe.288
Moravec’s diction and his use of metaphor are striking. Note the eagerness in the man’s tone, his conviction that the brave new world is almost upon us, and his undisguised love for his disembodied mind progeny. These kids are at once Cartesian and Hobbesian. Like Descartes’s cogito, they are mind only; like Hobbes’s brain, they are mechanical, and yet, unlike the Hobbesian machine brain, they churn away with no help from nature. Elsewhere in his book, Moravec predicts this transformation will all happen in fifty years. If these mental spawn are mere infants at the time of the author’s writing, not worthy of the adjective “intelligent,” if they are still helpless beings who need their programmer-dad hovering over them, this sorry and dependent state of affairs will not last long because soon, like HAL, they will take off on their own and, unlike us, they will not plod but run. We, the mere biological, resemble Vico’s giants, undeveloped, ignorant primitives.
Note, too, Moravec’s confidence in prediction and his use of the word that appears again and again in AI texts, “steps.” These logical steps forward will eliminate the problem of the messy bodies normally involved in procreation. The body is swept aside in a transcendence of nature itself or, one might say, nature herself. In this passage, the desire to erase the female body from reproduction is, to use yet another appropriate metaphor, “naked.” Is this womb envy, as it has sometimes been called, a masculine fantasy of self-reproduction without women? In a public debate with Kurzweil, moderated by Rodney Brooks, David Gelernter made the following comment: “Believe it or not, if we want more complete, fully functional people, we could have them right now, all natural ones. Consult me afterwards, and I’ll let you know how it’s done.”289 It seems to me Gelernter’s humor cuts awfully close to the bone.
Is the eagerness for transcendent man a horror or fear of universal early dependence on someone else’s body, a mother’s body in utero and a subsequent need for that body’s milk or the body of someone else for food and comfort? Isn’t it true that without another body, all of us mammals would be dead? Is Moravec also indulging in a fantasy of the eternal grown-up, the wish never to have been subservient to big people, perhaps especially big women? Won’t his machine kids throw infancy away forever once they become smart enough to avoid it, even though at the moment he is acting as proud father to his supernatural offspring? Moravec’s optimism is untouched by time. In 2009, while acknowledging the failures of AI’s early predictions, he makes another one himself: “By 2040, I believe, we will finally achieve the original goal of robotic
s and a thematic mainstay of science fiction: a freely moving machine with the intellectual capabilities of a human being.”290
Utopian thinking is nothing new. It has taken many forms, from Plato’s just Republic (with women admitted as rulers but no poets anywhere) to Rousseau’s happy man in a state of nature to Fourier’s phalanxes, in which everyone works for the collective good, and of course the Communist paradise. In a famous passage near the end of Literature and Revolution, Leon Trotsky predicted the new world of Communist man: “Man will become immeasurably stronger, wiser, and subtler; his body will become more harmonized, his movements more rhythmic, his voice more musical. The forms of life will become dynamically dramatic. The average human type will rise to the heights of an Aristotle, a Goethe, or a Marx. And above this ridge new peaks will rise.”291 When I first read this passage, I was sitting in a cubicle in my college library. I was writing a paper on socialist realism, the sorry art form sanctioned by the Soviet Republic. I was twenty-one years old, and I remember even then, hopeful as I was about improving the world, I thought the man was nuts. Next to Moravec’s rhetoric about our postbiological future, however, Trotsky’s language sounds almost tame. Although I risk sounding like a sourpuss, I am hardly alone in making the comment that although utopian fantasies have taken many different forms, what they share is failure. Not a single utopian experiment in the history of the human race has met with success.
Two years before Mind Children, the biologist and philosopher of science Donna Haraway published “A Cyborg Manifesto: Science, Technology and Socialist-Feminism in the Late Twentieth Century,” a text that may be compared to Moravec’s as an alternative vision of a transhuman future. Unlike Moravec, who is nothing if not sincere about his baby computers, Haraway announces from the outset that her text is ironic. Irony is by its nature a difficult mode of communication. It is a form of disguise that immediately complicates reading. In Haraway’s fantasy, which she announces as a myth, the arrival of the hybrid machine-organism is heralded as “a world-changing fiction,” in which traditional hierarchies are blurred in new slippery perceptual categories. Like Elizabeth Grosz’s Darwin, Haraway’s utopia avoids the sharp divisions of absolute category. The binary opposition nature/culture becomes “fields of difference.” Sex becomes “genetic engineering.” “A cyborg world,” she writes, “might be about lived social and bodily realities in which people are not afraid of their joint kinship with animals and machines, not afraid of permanently partial identities and contradictory standpoints.”292 For Haraway, fiction has power to direct thought and open new possibilities.
