? And we find it in a saying of a political movement that killed a quarter of its countrymen: Only the newborn baby is spotless.
? The new realization that government-sponsored mass murder can come from an anti-innatist belief system as easily as from an innatist one upends the postwar understanding that biological approaches to behavior are uniquely {157} sinister. An accurate appraisal of the cause of state genocides must look for beliefs common to Nazism and Marxism that launched them on their parallel trajectories, and for the beliefs specific to Marxism that led to the unique atrocities committed in its name. A new wave of historians and philosophers is doing exactly that. 48
Nazism and Marxism shared a desire to reshape humanity. "The alteration of men on a mass scale is necessary," wrote Marx; "the will to create mankind anew" is the core of National Socialism, wrote Hitler. 49 They also shared a revolutionary idealism and a tyrannical certainty in pursuit of this dream, with no patience for incremental reform or adjustments guided by the human consequences of their policies. This alone was a recipe for disaster. As Aleksandr Solzhenitsyn wrote in The Gulag Archipelago, "Macbeth's self-justifications were feeble -- and his conscience devoured him. Yes, even Iago was a little lamb too. The imagination and the spiritual strength of Shakespeare's evildoers stopped short at a dozen corpses. Because they had no ideology"
The ideological connection between Marxist socialism and National Socialism is not fanciful. 50 Hitler read Marx carefully while living in Munich in 1913, and may have picked up from him a fateful postulate that the two ideologies would share. 51 It is the belief that history is a preordained succession of conflicts between groups of people and that improvement in the human condition can come only from the victory of one group over the others. For the Nazis the groups were races; for the Marxists they were classes. For the Nazis the conflict was Social Darwinism; for the Marxists, it was class struggle. For the Nazis the destined victors were the Aryans; for the Marxists, they were the proletariat. The ideologies, once implemented, led to atrocities in a few steps: struggle (often a euphemism for violence) is inevitable and beneficial; certain groups of people (the non-Aryan races or the bourgeoisie) are morally inferior; improvements in human welfare depend on their subjugation or elimination. Aside from supplying a direct justification for violent conflict, the ideology of intergroup struggle ignites a nasty feature of human social psychology: the tendency to divide people into in-groups and out-groups and to treat the out-groups as less than human. It doesn't matter whether the groups are thought to be defined by their biology or by their history. Psychologists have found that they can create instant intergroup hostility by sorting people on just about any pretext, including the flip of a coin. 52
The ideology of group-against-group struggle explains the similar outcomes of Marxism and Nazism. The ideology of the Blank Slate helps explain some of the features that were unique to the Marxist states:
? If people do not differ in psychological traits like talent or drive, then anyone who is better off must be avaricious or larcenous (as I mentioned {158} earlier). Massive killing of kulaks and "rich" or "bourgeois" peasants was a feature of Lenin's and Stalin's Soviet Union, Mao's China, and Pol Pot's Cambodia.
? If the mind is structureless at birth and shaped by its experience, a society that wants the right kind of minds must control the experience ("It is on a blank page that the most beautiful poems are written"). 53 Twentieth-century Marxist states were not just dictatorships but totalitarian dictatorships. They tried to control every aspect of life: childrearing, education, clothing, entertainment, architecture, the arts, even food and sex. Authors in the Soviet Union were enjoined to become "engineers of human souls. " In China and Cambodia, mandatory communal dining halls, same-sex adult dormitories, and the separation of children from parents were recurring (and detested) experiments.
? If people are shaped by their social environments, then growing up bourgeois can leave a permanent psychological stain ("Only the newborn baby is spotless"). The descendants of landlords and "rich peasants" in postrevolutionary regimes bore a permanent stigma and were persecuted as readily as if bourgeois parentage were a genetic trait. Worse, since parentage is invisible but discoverable by third parties, the practice of outing people with a "bad background" became a weapon of social competition. That led to the atmosphere of denunciation and paranoia that made life in these regimes an Orwellian nightmare.
? If there is no human nature leading people to favor the interests of their families over "society," then people who produce more crops on their own plots than on communal farms whose crops are confiscated by the state must be greedy or lazy and punished accordingly. Fear rather than self-interest
? ? ? ? ? ? ? ? becomes the incentive to work.
? Most generally, if individual minds are interchangeable components of a superorganic entity called society, then the society, not the individual, is the natural unit of health and well-being and the proper beneficiary of human striving. The rights of the individual person have no place.
None of this is meant to impugn the Blank Slate as an evil doctrine, any more than a belief in human nature is an evil doctrine. Both are separated by a great many steps from the wicked acts committed under their banners, and they must be evaluated on factual grounds. But it is meant to overturn the simplistic linkage of the sciences of human nature with the moral catastrophes of the twentieth century. That glib association stands in the way of our desire to understand ourselves, and it stands in the way of the imperative to understand the causes of those catastrophes. All the more so if the causes have something to do with a side of ourselves we do not fully understand.

The Fear of Imperfectibility
But Nature then was sovereign in my mind, And mighty forms, seizing a youthful fancy, Had given a charter to irregular hopes.
In any age of uneventful calm
Among the nations, surely would my heart Have been possessed by similar desire;
But Europe at that time was thrilled with joy, France standing on the top of golden hours, And human nature seeming born again.
-- William Wordsworth1
? ? ? ? ? In Wordsworth's reminiscence we find the second fear raised by an innate psyche. The Romantic poet is exhilarated by the thought that human nature can be born again, and could only be depressed by the possibility that we are permanently saddled with our fatal flaws and deadly sins. Romantic political thinkers have the same reaction, because an unchanging human nature would seem to subvert all hope for reform. Why try to make the world a better place if people are rotten to the core and will just foul it up no matter what you do? It is no coincidence that the writings of Rousseau inspired both the Romantic movement in literature and the French Revolution in history, or that the 1960s would see a resurfacing of romanticism and radical politics in tandem. The philosopher John Passmore has shown that a yearning for a better world through a new and improved human nature is a recurring motif in Western thought, which he summarizes in a remark by D. H. Lawrence: "The Perfectibility of Man! Ah, heaven, what a dreary theme! "2
The dread of a permanently wicked human nature takes two forms. One is a practical fear: that social reform is a waste of time because human nature is unchangeable. The other is a deeper concern, which grows out of the Romantic belief that what is natural is good. According to the worry, if scientists {160} suggest it is "natural" -- part of human nature -- to be adulterous, violent, ethnocentric, and selfish, they would be implying that these traits are good, not just unavoidable.
As with the other convictions surrounding the Blank Slate, the fear of imperfectibility makes some sense in the context of twentieth-century history. A revulsion to the idea that people are naturally bellicose or xenophobic is an understandable reaction to an ideology that glorified war. One of the most memorable images I came across as a graduate student was a painting of a dead soldier in a muddy field. A uniformed ghost floated up from his corpse, one arm around a cloaked and faceless man, the other around a bare-breasted blond valkyrie. The caption read, "Happy those who with a glowing faith in one embrace clasped death and victory. " Was it a kitschy poster recruiting cannon fodder for an imperial exploit? A jingoistic monument in the castle of Prussian military aristocrat? No, Death and Victory was painted in 1922 by the great American artist John Singer Sargent and hangs prominently in one of the world's most famous scholarly libraries, the Widener at Harvard University.
That a piece of pro-death iconography should decorate these hallowed halls of learning is a testament to the warmongering mentality of decades past. War was thought to be invigorating, ennobling, the natural aspiration of men and nations. This belief led world leaders to sleepwalk into World War I and millions of men to enlist eagerly,
? ? oblivious to the carnage that lay ahead. Beginning with the disillusionment following that war and culminating in the widespread opposition to the war in Vietnam, Western sensibilities have steadily recoiled from the glorification of combat. Even recent works meant to honor the courage of fighting men, such as the movie Saving Private Ryan, show war as a hell that brave men endured at terrible cost to eliminate an identified evil, not something they could possibly feel "happy" about. Real wars today are waged with remote-control gadgetry to minimize casualties, sometimes at the cost of downgrading the war's objectives. In this climate any suggestion that war is "natural" will be met with indignant declarations to the contrary, such as the recurring Statements on Violence by social scientists averring that it is "scientifically incorrect" to say that humans have tendencies toward aggression. 3
A hostility to the idea that selfish sexual urges might be rooted in our nature comes from feminism. For millennia women have suffered under a double standard based on assumptions about differences between the sexes. Laws and customs punished the philandering of women more harshly than the philandering of men. Fathers and husbands stripped women of control over their sexuality by constraining their appearance and movement. Legal systems exonerated rapists or mitigated their punishment if the victim was thought to have aroused an irresistible urge by her dress or behavior. Authorities brushed off victims of harassment, stalking, and battering by assuming that these
{161} crimes were normal features of courtship or marriage. Because of a fear of accepting any idea that would seem to make these outrages "natural" or unavoidable, some schools of feminism have rejected any suggestion that men are born with greater sexual desire or jealousy. We saw in Chapter 7 that the claim that men want casual sex more than women do has been denounced by both the right and the left. Even heavier bipartisan fire has recently been aimed at Randy Thornhill and Craig Palmer for suggesting in their book A Natural History of Rape that rape is a consequence of men's sexuality. A spokesperson from the Feminist Majority Foundation called the book "scary" and "regressive" because it "almost validates the crime and blames the victim. "4 A spokesperson for the Discovery Institute, a creationist organization, testified at a U. S. congressional hearing that the book threatened the moral fabric upon which America is founded. 5
A third vice with political implications is selfishness. If people, like other animals, are driven by selfish genes, selfishness might seem inevitable or even a virtue. The argument is fallacious from the start because selfish genes do not necessarily grow selfish organisms. Still, let us consider the possibility that people might have some tendency to value their own interests and those of their family and friends above the interests of the tribe, society, or species. The political implications are spelled out in the two major philosophies of how societies should be organized, which make opposite assumptions about innate human selfishness:
It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest. We address ourselves, not to their humanity but to their self-
? ? ? ? ? love.
From each according to his abilities, to each according to his needs.
-- Adam Smith
-- Karl Marx
Smith the explainer of capitalism assumes that people will selfishly give their labor according to their needs and will be paid according to their abilities (because the payers are selfish, too). Marx the architect of communism and socialism assumes that in a socialist society of the future the butcher, the brewer, and the baker will provide us with dinner out of benevolence or self-actualization -- for why else would they cheerfully exert themselves according to their abilities and not according to their needs?
Those who believe that communism or socialism is the most rational form of social organization are aghast at the suggestion that they run against our selfish natures. For that matter, everyone, regardless of politics, has to be appalled at people who impose costs on society in pursuit of their individual {162} interests -- hunting endangered species, polluting rivers, destroying historic sites to build shopping malls, spraying graffiti on public monuments, inventing weapons that elude metal detectors. Equally disturbing are the outcomes of actions that make sense to the individual choosing them but are costly to society when everyone chooses them. Examples include overfishing a harbor, overgrazing a commons, commuting on a bumper-to-bumper freeway, or buying a sport utility vehicle to protect oneself in a collision because everyone else is driving a sport utility vehicle. Many people dislike the suggestion that humans are inclined to selfishness because it would seem to imply that these self-defeating patterns of behavior are inevitable, or at least reducible only through p~ermanent coercive measures.
The fear of imperfectibility and the resultant embrace of the Blank Slate are rooted in a pair of fallacies. We have already met the naturalistic fallacy, the belief that whatever happens in nature is good. One might think that the belief was irreversibly tainted by Social Darwinism, but it was revived by the romanticism of the 1960s and 1970s. The
? environmentalist movement, in particular, often appeals to the goodness of nature to promote conservation of natural environments, despite their ubiquitous gore. For example, predators such as wolves, bears, and sharks have been given an image makeover as euthanists of the old and the lame, and thus worthy of preservation or reintroduction. It would seem to follow that anything we have inherited from this Eden is healthy and proper, so a claim that aggression or rape is "natural," in the sense of having been favored by evolution, is tantamount to saying that it is good.
The naturalistic fallacy leads quickly to its converse, the moralistic fallacy: that if a trait is moral, it must be found in nature. That is, not only does "is" imply "ought," but "ought" implies "is. " Nature, including human nature, is stipulated to have only virtuous traits (no needless killings, no rapacity, no exploitation), or no traits at all, because the alternative is too horrible to accept. That is why the naturalistic and moralistic fallacies are so often associated with the Noble Savage and the Blank Slate.
Defenders of the naturalistic and moralistic fallacies are not made of straw but include prominent scholars and writers. For example, in response to Thornhill's earlier writings on rape, the feminist scholar Susan Brownmiller wrote, "It seems quite clear that the biologicization of rape and the dismissal of social or 'moral' factors will . . . tend to legitimate rape. . . . It is reductive and reactionary to isolate rape from other forms of violent antisocial behavior and dignify it with adaptive significance. "6 Note the fallacy: if something is explained with biology, it has been "legitimated"; if something is shown to be adaptive, it has been "dignified. " Similarly, Stephen Jay Gould wrote of another discussion of rape in animals, "By falsely describing an inherited behavior in birds with an old name for a deviant human action, we subtly suggest that true {163} rape -- our own kind -- might be a natural behavior with Darwinian advantages to certain people as well. "7 The implicit rebuke is that to describe an act as "natural" or as having "Darwinian advantages" is somehow to condone it.
The moralistic fallacy, like the naturalistic fallacy, is, well, a fallacy, as we learn from this Arlo and Janis cartoon:
The boy has biology on his side. 8 George Williams, the revered evolutionary biologist, describes the natural world as "grossly immoral. "9 Having no foresight or compassion, natural selection "can honestly be described as a process for maximizing short-sighted selfishness. " On top of all the miseries inflicted by predators and parasites, the members of a species show no pity to their own kind. Infanticide, siblicide, and rape can be observed in many kinds of animals; infidelity is common even in so-called pair-bonded species; cannibalism can be expected in all species that are not strict vegetarians; death from fighting is more common in most animal species than it is in the most violent American cities. 10 Commenting on how biologists used to describe the killing of starving deer by mountain lions as an act of mercy, Williams wrote:
The simple facts are that both predation and starvation are painful prospects for deer, and that the lion's lot is no more enviable. Perhaps biology would have been able to mature more rapidly in a culture not dominated by Judeo-Christian theology and the Romantic tradition. It might have been well served by the First Holy Truth from [Buddha's] Sermon at Benares: "Birth is painful, old age is painful, sickness is painful, death is painful. . . "11
As soon as we recognize that there is nothing morally commendable about the products of evolution, we can describe human psychology honestly, without the fear that identifying a "natural" trait is the same as condoning it. As Katharine Hepburn says to Humphrey Bogart in The African Queen, "Nature, Mr. Allnut, is what we are put in this world to rise above. "
Crucially, this cuts both ways. Many commentators from the religious and cultural right believe that any behavior that strikes them as biologically {164} atypical, such as homosexuality, voluntary childlessness, and women who assume traditional male roles or vice versa, should be condemned because it is "unnatural. " For example, the popular talk-show host Laura Schlesinger has declared, "I am getting people to stop doing wrong and start doing right. " As part of this crusade she has called on gay people to submit to therapy to change their sexual orientation, because
? ? ? ? ? ? ? ? ? homosexuality is a "biological error. " This kind of moral reasoning can come only from people who know nothing about biology. Most activities that moral people extol -- being faithful to one's spouse, turning the other cheek, treating every child as precious, loving thy neighbor as thyself -- are "biological errors" and are utterly unnatural in the rest of the living world.
Acknowledging the naturalistic fallacy does not mean that facts about human nature are irrelevant to our choices. 12 The political scientist Roger Masters, noting that the naturalistic fallacy can be invoked too glibly to deny the relevance of biology to human affairs, points out, "When the physician says a patient ought to have an operation because the facts show appendicitis, the patient is unlikely to complain about a fallacious logical deduction. "13 Acknowledging the naturalistic fallacy implies only that discoveries about human nature do not, by themselves, dictate our choices. The facts must be combined with a statement of values and a method of resolving conflicts among them. Given the fact of appendicitis, the value that health is desirable, and the conviction that the pain and expense of the operation are outweighed by the resulting gain in health, one ought to have the operation.
Suppose rape is rooted in a feature of human nature, such as that men want sex across a wider range of circumstances than women do. It is also a feature of human nature, just as deeply rooted in our evolution, that women want control over when and with whom they have sex. It is inherent to our value system that the interests of women should not be subordinated to those of men, and that control over one's body is a fundamental right that trumps other people's desires. So rape is not tolerated, regardless of any possible connection to the nature of men's sexuality. Note how this calculus requires a "deterministic" and "essentialist" claim about human nature: that women abhor being raped. Without that claim we would have no way to choose between trying to deter rape and trying to socialize women to accept it, which would be perfectly compatible with the supposedly progressive doctrine that we are malleable raw material.
In other cases, the best way to resolve a conflict is not as obvious. The psychologists Martin Daly and Margo Wilson have documented that stepparents are far more likely to abuse a child than are biological parents. The discovery was by no means banal: many parenting experts insist that the abusive stepparent is a myth originating in Cinderella stories and that parenting is a "role" that anyone can take on. Daly and Wilson had originally examined the abuse statistics to test a prediction from evolutionary psychology. 14 Parental love is selected over {165} evolutionary time because it compels parents to protect and nurture their children, who are likely to carry the genes giving rise to parental love. In any species in which someone else's offspring are likely to enter the family circle, selection will favor a tendency to prefer one's own, because in the cold reckoning of natural selection an investment in the unrelated children would go to waste. A parent's patience will tend to run out with stepchildren more quickly than with biological children, and in extreme cases this can lead to abuse.
Does all this mean that social service agencies should monitor stepparents more closely than biological parents? Not so fast. The vast majority of both kinds of parents never commit abuse, so putting stepparents under a cloud of suspicion would be unfair to millions of innocent people. As the legal scholar Owen Jones points out, the evolutionary analysis of stepparenting -- or of anything else -- has no automatic policy implications.
Rather, it delineates a tradeoff and forces us to choose an optimum along it. In this case, the tradeoff is between minimizing child abuse while stigmatizing stepparents, on one hand, and being maximally fair to stepparents while tolerating an increase in child abuse, on the other. 15 If we did not know that people are predisposed to lose patience with stepchildren faster than with biological children, we would implicitly choose one end of this tradeoff -- ignoring step- parenting as a risk factor altogether, and tolerating the extra cases of child abuse -- without even realizing it.
An understanding of human nature with all its weaknesses can enrich not just our policies but our personal lives. Families with stepchildren tend to be less happy and more fragile than families with biological children, largely because of tensions over how much time, patience, and money the stepparents should expend. Many stepparents, nonetheless, are kind and generous to a spouse's children, in part out of love for the spouse. Still, there is a difference between the instinctive love that parents automatically lavish on their own children and the deliberate kindness and generosity that wise stepparents extend to their stepchildren. Understanding this difference, Daly and Wilson suggest, could enhance a marriage. 16 Though a marriage based on strict tit-for-tat reciprocity is generally miserable, a good marriage finds each spouse appreciating the sacrifices that the other has made over the long haul. Acknowledging a partner's conscious benevolence toward one's children may ultimately breed less resentment and misunderstanding than demanding such benevolence as a matter of course and begrudging any ambivalence the partner may feel. It is one of many ways in which a realism about the imperfect emotions we actually have may bring more happiness than an illusion about the ideal emotions we wish we had. ~
So if we are put in this world to rise above nature, how do we do it? Where in the causal chain of evolved genes building a neural computer do we find a {166} chink into which we can fit the seemingly unmechanical event of
? ? ? ? ? ? ? "choosing values"? By allowing for choice, are we just inviting a ghost back into the machine?
The question is itself a symptom of the Blank Slate. If one starts off thinking the slate is blank, then when someone proposes an innate desire one will mentally plunk it onto the barren surface in one's imagination and conclude that it must be an ineluctable urge, because there is nothing else on the slate to counteract it. Selfish thoughts translate into selfish behavior, aggressive urges beget natural-born killers, a taste for multiple sexual partners means that men just can't help fooling around. For example, when the primatologist Michael Ghiglieri appeared on the National Public Radio program Science Friday to talk about his book on violence, the interviewer asked, "You explain rape and murder and war and all the bad things that men do as something -- if I would just boil it down -- something they can't help because of its -- it's locked up in their evolutionary genes there? "17
If, however, the mind is a system with many parts, then an innate desire is just one component among others. Some faculties may endow us with greed or lust or malice, but others may endow us with sympathy, foresight, selfrespect, a desire for respect from others, and an ability to learn from our own experiences and those of our neighbors. These are physical circuits residing in the prefrontal cortex and other parts of the brain, not occult powers of a poltergeist, and they have a genetic basis and an evolutionary history no less than the primal urges. It is only the Blank Slate and the Ghost in the Machine that make people think that drives are "biological" but that thinking and decision making are something else.
The faculties underlying empathy, foresight, and self-respect are information-processing systems that accept input and commandeer other parts of the brain and body. They are combinatorial systems, like the mental grammar underlying language, capable of cranking out an unlimited number of ideas and courses of action. Personal and social change can come about when people exchange information that affects those mechanisms -- even if we are nothing but meat puppets, glorified clockwork, or lumbering robots created by selfish genes.
Not only is acknowledging human nature compatible with social and moral progress, but it can help explain the obvious progress that has taken place over millennia. Customs that were common throughout history and prehistory -- slavery, punishment by mutilation, execution by torture, genocide for convenience, endless blood feuds, the summary killing of strangers, rape as the spoils of war, infanticide as a form of birth control, and the legal ownership of women -- have vanished from large parts of the world.
The philosopher Peter Singer has shown how continuous moral progress can emerge from a fixed moral sense. 18 Suppose we are endowed with a {167} conscience that treats other persons as targets of sympathy and inhibits us from harming or exploiting them. Suppose, too, that we have a mechanism for assessing whether a living thing gets
to be classified as a person. (After all, we don't want to classify plants as persons and starve before we would eat them. ) Singer explains moral improvement in the title of his book: The Expanding Circle. People have steadily expanded the mental dotted line that embraces the entities considered worthy of moral consideration. The circle has been poked outward from the family and village to the clan, the tribe, the nation, the race, and most recently (as in the Universal Declaration of Human Rights) to all of humanity. It has been slackened from royalty, aristocracy, and property holders to all men. It has grown from including only men to including women, children, and newborns. It has crept outward to embrace criminals, prisoners of war, enemy civilians, the dying, and the mentally handicapped. Nor are the possibilities for moral progress over. Today some people want to enlarge the circle to include great apes, warm-blooded creatures, or animals with central nervous systems. Some want to count in zygotes, blastocysts, fetuses, and the brain-dead. Still others want to embrace species, ecosystems, or the entire planet. This sweeping change in sensibilities, the driving force in the moral history of our species, did not require a blank slate or a ghost in the machine. It could have arisen from a moral gadget containing a single knob or slider that adjusts the size of the circle embracing the entities whose interests we treat as comparable to our own.
The expansion of the moral circle does not have to be powered by some mysterious drive toward goodness. It may come from the interaction between the selfish process of evolution and a law of complex systems. The biologists
John Maynard Smith and Eors Szathmary and the journalist Robert Wright have explained how evolution can lead to greater and greater degrees of cooperation. 19 Repeatedly in the history of life, replicators have teamed up, specialized to divide the labor, and coordinated their behavior. It happens because replicators often find themselves in non-zero- sum games, in which particular strategies adopted by two players can leave them both better off (as opposed to a zero- sum game, where one player's profit is another player's loss). An exact analogy is found in the play by William Butler Yeats in which a blind man carries a lame man on his shoulders, allowing both of them to get around. During the evolution of life this dynamic has led replicating molecules to team up in chromosomes, organelles to team up in cells, cells to agglomerate into complex organisms, and organisms to hang out in societies. Independent agents repeatedly made their fate hostage to a larger system, not because they are inherently civic-minded but because they benefited from the division of labor and developed ways of damping conflicts among the agents making up the system.
Human societies, like living things, have become more complicated and cooperative over time. Again, it is because
? ? ? ? agents do better when they team up {168} and specialize in pursuit of their shared interests, as long as they solve the problems of exchanging information and punishing cheaters. If I have more fruit than I can eat and you have more meat than you can eat, it pays each of us to trade our surplus with the other. If we face a common enemy, then, as Benjamin Franklin put it, "We must all hang together, or assuredly we shall all hang separately. "
Wright argues that three features of human nature led to a steady expansion of the circle of human cooperators. One is the cognitive wherewithal to figure out how the world works. This yields know-how worth sharing and an ability to spread goods and information over larger territories, both of which expand opportunities for gains in trade. A second is language, which allows technology to be shared, bargains to be struck, and agreements to be enforced. A third is an emotional repertoire -- sympathy, trust, guilt, anger, self-esteem -- that impels us to seek new cooperators, maintain relationships with them, and safeguard the relationships against possible exploitation. Long ago these endowments put our species on a moral escalator. Our mental circle of respect-worthy persons expanded in tandem with our physical circle of allies and trading partners. As technology accumulates and people in more parts of the planet become interdependent, the hatred between them tends to decrease, for the simple reason that you can't kill someone and trade with him too.
Non-zero-sum games arise not just from people's ability to help one another but from their ability to refrain from hurting one another. In many disputes, both sides come out ahead by dividing up the savings made available from not having to fight. That provides an incentive to develop technologies of conflict resolution, such as mediation, face- saving measures, measured restitution and retribution, and legal codes. The primatologist Frans de Waal has argued that the rudiments of conflict resolution may be found in many species of primates. 20 The human forms are ubiquitous across cultures, as universal as the conflicts of interest they are designed to defuse. 21
Though the evolution of the expanding circle (its ultimate cause) may sound pragmatic or even cynical, the psychology of the expanding circle (its proximate cause) need not be. Once the sympathy knob is in place, having evolved to enjoy the benefits of cooperation and exchange, it can be cranked up by new kinds of information that other folks are similar to oneself. Words and images from erstwhile enemies can trigger the sympathy response. A historical record can warn against self-defeating cycles of vendetta. A cosmopolitan awareness may lead people to think, "There but for fortune go I. " An expansion of sympathy may come from something as basic as the requirement to be logically consistent when imploring other people to behave in certain ways: people come to realize that they cannot force others to abide by rules that they themselves flout. Egoistic, sexist, racist, and xenophobic attitudes are logically {169} inconsistent with the demand that everyone respect a single code of behavior. 22 Peaceful coexistence, then, does not have to come from pounding selfish desires out of people. It can come from pitting some desires -- the desire for safety, the benefits of cooperation, the ability to formulate and recognize universal codes of behavior -- against the desire for immediate gain. These are just a few of the ways in which moral and social progress can ratchet upwards, not in spite of a fixed human~nature but because of it.
When you stop to think about it, the idea of a pliant human nature does not deserve its reputation for optimism and uplift. If it did, B. F. Skinner would have been lauded as a great humanitarian when he argued that society should apply the technology of conditioning to humans, shaping people to use contraception, conserve energy, make peace, and avoid crowded cities. 23 Skinner was a staunch blank-slater and a passionate Utopian. His uncommonly pure vision allows us to examine the implications of the "optimistic" denial of human nature. Given his premise that undesirable behavior is not in the genes but a product of the environment, it follows that we should control that environment -- for all we would be doing is replacing haphazard schedules of reinforcement by planned ones.
Why are most people repelled by this vision? Critics of Skinner's Beyond Freedom and Dignity pointed out that no one doubts that behavior can be controlled; putting a gun to someone's head or threatening him with torture are time- honored techniques. 24 Even Skinner's preferred method of operant conditioning required starving the organism to 80 percent of its free-feeding weight and confining it to a box where schedules of reinforcement were carefully controlled. The issue is not whether we can change human behavior, but at what cost.
Since we are not just products of our environments, there will be costs. People have inherent desires such as comfort, love, family, esteem, autonomy, aesthetics, and self-expression, regardless of their history of reinforcement, and they suffer when the freedom to exercise the desires is thwarted. Indeed, it is difficult to define psychological pain without some notion of human nature. (Even the young Marx appealed to a "species character," with an impulse for creative activity, as the basis for his theory of alienation. ) Sometimes we may choose to impose suffering to control behavior, as when we punish people who cause avoidable suffering in others. But we cannot pretend that we can reshape behavior without infringing in some way on other people's freedom and happiness. Human nature is the reason we do not surrender our freedom to behavioral engineers.
Inborn human desires are a nuisance to those with Utopian and totalitarian visions, which often amount to the same
? ? ? ? ? ? ? thing. What stands in the way of {170} most Utopias is not pestilence and drought but human behavior. So Utopians have to think of ways to control behavior, and when propaganda doesn't do the trick, more emphatic techniques are tried. The Marxist Utopians of the twentieth century, as we saw, needed a tabula rasa free of selfishness and family ties and used totalitarian measures to scrape the tablets clean or start over with new ones. As Bertolt Brecht said of the East German government, "If the people did not do better the government would dismiss the people and elect a new one. " Political philosophers and historians who have recently "reflected on our ravaged century," such as Isaiah Berlin, Kenneth Minogue, Robert Conquest, Jonathan Glover, James Scott, and Daniel Chirot, have pointed to Utopian dreams as a major cause of twentieth-century nightmares. 25 For that matter, Wordsworth's revolutionary France, "thrilled with joy" while human nature was "born again," turned out to be no picnic either.
It's not just behaviorists and Stalinists who forgot that a denial of human nature may have costs in freedom and happiness. Twentieth-century Marxism was part of a larger intellectual current that has been called Authoritarian High Modernism: the conceit that planners could redesign society from the top down using "scientific" principles. 26 The architect Le Corbusier, for example, argued that urban planners should not be fettered by traditions and tastes, since they only perpetuated the overcrowded chaos of the cities of his day. "We must build places where mankind will be reborn," he wrote. "Each man will live in an ordered relation to the whole. "27 In Le Corbusier's Utopia, planners would begin with a "clean tablecloth" (sound familiar? ) and mastermind all buildings and public spaces to service "human needs. " They had a minimalist conception of those needs: each person was thought to require a fixed amount of air, heat, light, and space for eating, sleeping, working, commuting, and a few other activities. It did not occur to Le Corbusier that intimate gatherings with family and friends might be a human need, so he proposed large communal dining halls to replace kitchens. Also missing from his list of needs was the desire to socialize in small groups in public places, so he planned his cities around freeways, large buildings, and vast open plazas, with no squares or crossroads in which people would feel comfortable hanging out to schmooze. Homes were "machines for living," free of archaic inefficiencies like gardens and ornamentation, and thus were efficiently packed together in large, rectangular housing projects.
Le Corbusier was frustrated in his aspiration to flatten Paris, Buenos Aires, and Rio de Janeiro and rebuild them according to his scientific principles. But in the 1950s he was given carte blanche to design Chandigarh, the capital of the Punjab, and one of his disciples was given a clean tablecloth for Brasilia, the capital of Brazil. Today, both cities are notorious as uninviting wastelands detested by the civil servants who live in them. Authoritarian High Modernism also led to the "urban renewal" projects in many American cities {171} during the 1960s that replaced vibrant neighborhoods with freeways, high-rises, and empty windswept plazas.
Social scientists, too, have sometimes gotten carried away with dreams of social engineering. The child psychiatrist Bruce Perry, concerned that ghetto mothers are not giving children the enriched environment needed by their plastic brains, believes we must "transform our culture": "We need to change ' our child rearing practices, we need to change the malignant and destructive view that children are the property of their biological parents. Human beings evolved not as individuals, but as communities. . . . Children belong to the community, they are entrusted to their parents. "28 Now, no one could object to rescuing children from neglect or cruelty, but if Perry's transformed culture came to pass, men with guns could break up any family that did not conform to the latest fad in parenting theory. As we will see in the chapter on children, most of these fads are based on flawed studies that treat every correlation between parents and children as proof of causation. Asian American and African American parents often flout the advice of the child-development gurus, using more traditional, authoritarian styles of childrearing that in all likelihood do their children no lasting harm. 29 The parenting police could strip them of their children.
Nothing in the concept of human nature is inconsistent with the ideals of feminism, or so I will argue in the chapter on gender. But some feminist theoreticians have embraced the Blank Slate and with it an authoritarian political philosophy that would give the government sweeping powers to implement their vision of gender-free minds. In a 1975 dialogue, Simone de Beauvoir said: "No woman should be authorized to stay at home to raise her children. Society should be totally different. Women should not have that choice, precisely because if there is such a choice, too many women will make that one. "30 Gloria Steinem was a bit more liberal; in a 1970 Time article she wrote: "The [feminist] revolution would not take away the option of being a housewife. A woman who prefers to be her husband's housekeeper and/or hostess would receive a percentage of his pay determined by the domestic-relations courts. "31 Betty Friedan has spoken out in favor of "compulsory preschool" for two-year-olds. 32 Catharine MacKinnon (who with Andrea Dworkin has pushed for laws against erotica) has said, "What you need is people who see through literature like Andrea Dworkin, who see through law like me, to see through art and create the uncompromised women's visual vocabulary"33 -- oblivious to the danger inherent in a few intellectuals' arrogating the role of deciding which art and literature the rest of society will enjoy.
In an interview in the New York Times Magazine, Carol Gilligan explained the implications of her (preposterous) theory that behavior problems in boys, such as stuttering and hyperactivity, are caused by cultural norms that
? ? ? ? ? ? ? ? ? ? ? pressure them to separate from their mothers: {172}
q: You would argue that men's biology is not so powerful that we can't change the culture of men? a: Right. We have to build a culture that doesn't reward that separation from the person who raised them. . . .
q: Everything you've said suggests that unless men change in fundamental ways, we're not going to have a sea change in the culture.
a: That seems right to me. 34
An incredulous reader, hearing an echo of the attempt to engineer a "new socialist man," asked, "Does anyone, even in academia, still believe that this sort of thing turns out well? "35 He was right to be concerned. In many schools,
teachers have been told, falsely, that there is an "opportunity zone" in which a child's gender identification is malleable. They have used this zone to try to stamp out boyhood: banning same-sex play groups and birthday parties, forcing children to do gender-atypical activities, suspending boys who run during recess or play cops and robbers. 36 In her book The War Against Boys, the philosopher Christina Hoff Sommers rightly calls this agenda "meddlesome, abusive, and quite beyond what educators in a free society are mandated to do. "37
Feminism, far from needing a blank slate, needs the opposite, a clear conception of human nature. One of the most pressing feminist causes today is the condition of women in the developing world. In many places female fetuses are selectively aborted, newborn girls are killed, daughters are malnourished and kept from school, adolescent girls have their genitals cut out, young women are cloaked from head to toe, adulteresses are stoned to death, and widows are expected to fall onto their husbands' funeral pyres. The relativist climate in many academic circles does not allow these horrors to be criticized because they are practices of other cultures, and cultures are superorganisms that, like people, have inalienable rights. To escape this trap, the feminist philosopher Martha Nussbaum has invoked "central functional capabilities" that all humans have a right to exercise, such as physical integrity, liberty of conscience, and political participation. She has been criticized in turn for taking on a colonial "civilizing mission" or "white woman's burden," in which arrogant Europeans would instruct the poor people of the world in what they want. But Nussbaum's moral argument is defensible if her "capabilities" are grounded, directly or indirectly, in a universal human nature. Human nature provides a yardstick to identify suffering in any member of our species.
The existence of a human nature is not a reactionary doctrine that dooms us to eternal oppression, violence, and greed. Of course we should try to reduce harmful behavior, just as we try to reduce afflictions like hunger, disease, and {173} the elements. But we fight those afflictions not by denying the pesky facts of nature but by turning some of them against the others. For efforts at social change to be effective, they must identify the cognitive and moral resources that make some kinds of change possible. And for the efforts to be humane, they must acknowledge the universal pleasures and pains that make some kinds of change desirable.

The Fear of Determinism
This chapter is not about the boo-word that is frequently (and inaccurately) hurled at any explanation of a behavioral tendency that mentions evolution or genetics. It is about determinism in its original sense, the concept that is opposed to "free will" in introductory philosophy courses. The fear of determinism in this sense is captured in a limerick:
There was a young man who said: "Damn! It grieves me to think that I am Predestined to move
In a circumscribed groove:
In fact, not a bus, but a tram. "
In the traditional conception of a ghost in the machine, our bodies are inhabited by a self or a soul that chooses the behavior to be executed by the body. These choices are not compelled by some prior physical event, like one billiard ball smacking into another and sending it into a corner pocket. The idea that our behavior is caused by the physiological activity of a genetically shaped brain would seem to refute the traditional view. It would make our behavior an automatic consequence of molecules in motion and leave no room for an uncaused behavior-chooser.
? And we find it in a saying of a political movement that killed a quarter of its countrymen: Only the newborn baby is spotless.
? The new realization that government-sponsored mass murder can come from an anti-innatist belief system as easily as from an innatist one upends the postwar understanding that biological approaches to behavior are uniquely {157} sinister. An accurate appraisal of the cause of state genocides must look for beliefs common to Nazism and Marxism that launched them on their parallel trajectories, and for the beliefs specific to Marxism that led to the unique atrocities committed in its name. A new wave of historians and philosophers is doing exactly that. 48
Nazism and Marxism shared a desire to reshape humanity. "The alteration of men on a mass scale is necessary," wrote Marx; "the will to create mankind anew" is the core of National Socialism, wrote Hitler. 49 They also shared a revolutionary idealism and a tyrannical certainty in pursuit of this dream, with no patience for incremental reform or adjustments guided by the human consequences of their policies. This alone was a recipe for disaster. As Aleksandr Solzhenitsyn wrote in The Gulag Archipelago, "Macbeth's self-justifications were feeble -- and his conscience devoured him. Yes, even Iago was a little lamb too. The imagination and the spiritual strength of Shakespeare's evildoers stopped short at a dozen corpses. Because they had no ideology"
The ideological connection between Marxist socialism and National Socialism is not fanciful. 50 Hitler read Marx carefully while living in Munich in 1913, and may have picked up from him a fateful postulate that the two ideologies would share. 51 It is the belief that history is a preordained succession of conflicts between groups of people and that improvement in the human condition can come only from the victory of one group over the others. For the Nazis the groups were races; for the Marxists they were classes. For the Nazis the conflict was Social Darwinism; for the Marxists, it was class struggle. For the Nazis the destined victors were the Aryans; for the Marxists, they were the proletariat. The ideologies, once implemented, led to atrocities in a few steps: struggle (often a euphemism for violence) is inevitable and beneficial; certain groups of people (the non-Aryan races or the bourgeoisie) are morally inferior; improvements in human welfare depend on their subjugation or elimination. Aside from supplying a direct justification for violent conflict, the ideology of intergroup struggle ignites a nasty feature of human social psychology: the tendency to divide people into in-groups and out-groups and to treat the out-groups as less than human. It doesn't matter whether the groups are thought to be defined by their biology or by their history. Psychologists have found that they can create instant intergroup hostility by sorting people on just about any pretext, including the flip of a coin. 52
The ideology of group-against-group struggle explains the similar outcomes of Marxism and Nazism. The ideology of the Blank Slate helps explain some of the features that were unique to the Marxist states:
? If people do not differ in psychological traits like talent or drive, then anyone who is better off must be avaricious or larcenous (as I mentioned {158} earlier). Massive killing of kulaks and "rich" or "bourgeois" peasants was a feature of Lenin's and Stalin's Soviet Union, Mao's China, and Pol Pot's Cambodia.
? If the mind is structureless at birth and shaped by its experience, a society that wants the right kind of minds must control the experience ("It is on a blank page that the most beautiful poems are written"). 53 Twentieth-century Marxist states were not just dictatorships but totalitarian dictatorships. They tried to control every aspect of life: childrearing, education, clothing, entertainment, architecture, the arts, even food and sex. Authors in the Soviet Union were enjoined to become "engineers of human souls. " In China and Cambodia, mandatory communal dining halls, same-sex adult dormitories, and the separation of children from parents were recurring (and detested) experiments.
? If people are shaped by their social environments, then growing up bourgeois can leave a permanent psychological stain ("Only the newborn baby is spotless"). The descendants of landlords and "rich peasants" in postrevolutionary regimes bore a permanent stigma and were persecuted as readily as if bourgeois parentage were a genetic trait. Worse, since parentage is invisible but discoverable by third parties, the practice of outing people with a "bad background" became a weapon of social competition. That led to the atmosphere of denunciation and paranoia that made life in these regimes an Orwellian nightmare.
? If there is no human nature leading people to favor the interests of their families over "society," then people who produce more crops on their own plots than on communal farms whose crops are confiscated by the state must be greedy or lazy and punished accordingly. Fear rather than self-interest
? ? ? ? ? ? ? ? becomes the incentive to work.
? Most generally, if individual minds are interchangeable components of a superorganic entity called society, then the society, not the individual, is the natural unit of health and well-being and the proper beneficiary of human striving. The rights of the individual person have no place.
None of this is meant to impugn the Blank Slate as an evil doctrine, any more than a belief in human nature is an evil doctrine. Both are separated by a great many steps from the wicked acts committed under their banners, and they must be evaluated on factual grounds. But it is meant to overturn the simplistic linkage of the sciences of human nature with the moral catastrophes of the twentieth century. That glib association stands in the way of our desire to understand ourselves, and it stands in the way of the imperative to understand the causes of those catastrophes. All the more so if the causes have something to do with a side of ourselves we do not fully understand.

The Fear of Imperfectibility
But Nature then was sovereign in my mind, And mighty forms, seizing a youthful fancy, Had given a charter to irregular hopes.
In any age of uneventful calm
Among the nations, surely would my heart Have been possessed by similar desire;
But Europe at that time was thrilled with joy, France standing on the top of golden hours, And human nature seeming born again.
-- William Wordsworth1
? ? ? ? ? In Wordsworth's reminiscence we find the second fear raised by an innate psyche. The Romantic poet is exhilarated by the thought that human nature can be born again, and could only be depressed by the possibility that we are permanently saddled with our fatal flaws and deadly sins. Romantic political thinkers have the same reaction, because an unchanging human nature would seem to subvert all hope for reform. Why try to make the world a better place if people are rotten to the core and will just foul it up no matter what you do? It is no coincidence that the writings of Rousseau inspired both the Romantic movement in literature and the French Revolution in history, or that the 1960s would see a resurfacing of romanticism and radical politics in tandem. The philosopher John Passmore has shown that a yearning for a better world through a new and improved human nature is a recurring motif in Western thought, which he summarizes in a remark by D. H. Lawrence: "The Perfectibility of Man! Ah, heaven, what a dreary theme! "2
The dread of a permanently wicked human nature takes two forms. One is a practical fear: that social reform is a waste of time because human nature is unchangeable. The other is a deeper concern, which grows out of the Romantic belief that what is natural is good. According to the worry, if scientists {160} suggest it is "natural" -- part of human nature -- to be adulterous, violent, ethnocentric, and selfish, they would be implying that these traits are good, not just unavoidable.
As with the other convictions surrounding the Blank Slate, the fear of imperfectibility makes some sense in the context of twentieth-century history. A revulsion to the idea that people are naturally bellicose or xenophobic is an understandable reaction to an ideology that glorified war. One of the most memorable images I came across as a graduate student was a painting of a dead soldier in a muddy field. A uniformed ghost floated up from his corpse, one arm around a cloaked and faceless man, the other around a bare-breasted blond valkyrie. The caption read, "Happy those who with a glowing faith in one embrace clasped death and victory. " Was it a kitschy poster recruiting cannon fodder for an imperial exploit? A jingoistic monument in the castle of Prussian military aristocrat? No, Death and Victory was painted in 1922 by the great American artist John Singer Sargent and hangs prominently in one of the world's most famous scholarly libraries, the Widener at Harvard University.
That a piece of pro-death iconography should decorate these hallowed halls of learning is a testament to the warmongering mentality of decades past. War was thought to be invigorating, ennobling, the natural aspiration of men and nations. This belief led world leaders to sleepwalk into World War I and millions of men to enlist eagerly,
? ? oblivious to the carnage that lay ahead. Beginning with the disillusionment following that war and culminating in the widespread opposition to the war in Vietnam, Western sensibilities have steadily recoiled from the glorification of combat. Even recent works meant to honor the courage of fighting men, such as the movie Saving Private Ryan, show war as a hell that brave men endured at terrible cost to eliminate an identified evil, not something they could possibly feel "happy" about. Real wars today are waged with remote-control gadgetry to minimize casualties, sometimes at the cost of downgrading the war's objectives. In this climate any suggestion that war is "natural" will be met with indignant declarations to the contrary, such as the recurring Statements on Violence by social scientists averring that it is "scientifically incorrect" to say that humans have tendencies toward aggression. 3
A hostility to the idea that selfish sexual urges might be rooted in our nature comes from feminism. For millennia women have suffered under a double standard based on assumptions about differences between the sexes. Laws and customs punished the philandering of women more harshly than the philandering of men. Fathers and husbands stripped women of control over their sexuality by constraining their appearance and movement. Legal systems exonerated rapists or mitigated their punishment if the victim was thought to have aroused an irresistible urge by her dress or behavior. Authorities brushed off victims of harassment, stalking, and battering by assuming that these
{161} crimes were normal features of courtship or marriage. Because of a fear of accepting any idea that would seem to make these outrages "natural" or unavoidable, some schools of feminism have rejected any suggestion that men are born with greater sexual desire or jealousy. We saw in Chapter 7 that the claim that men want casual sex more than women do has been denounced by both the right and the left. Even heavier bipartisan fire has recently been aimed at Randy Thornhill and Craig Palmer for suggesting in their book A Natural History of Rape that rape is a consequence of men's sexuality. A spokesperson from the Feminist Majority Foundation called the book "scary" and "regressive" because it "almost validates the crime and blames the victim. "4 A spokesperson for the Discovery Institute, a creationist organization, testified at a U. S. congressional hearing that the book threatened the moral fabric upon which America is founded. 5
A third vice with political implications is selfishness. If people, like other animals, are driven by selfish genes, selfishness might seem inevitable or even a virtue. The argument is fallacious from the start because selfish genes do not necessarily grow selfish organisms. Still, let us consider the possibility that people might have some tendency to value their own interests and those of their family and friends above the interests of the tribe, society, or species. The political implications are spelled out in the two major philosophies of how societies should be organized, which make opposite assumptions about innate human selfishness:
It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest. We address ourselves, not to their humanity but to their self-
? ? ? ? ? love.
From each according to his abilities, to each according to his needs.
-- Adam Smith
-- Karl Marx
Smith the explainer of capitalism assumes that people will selfishly give their labor according to their needs and will be paid according to their abilities (because the payers are selfish, too). Marx the architect of communism and socialism assumes that in a socialist society of the future the butcher, the brewer, and the baker will provide us with dinner out of benevolence or self-actualization -- for why else would they cheerfully exert themselves according to their abilities and not according to their needs?
Those who believe that communism or socialism is the most rational form of social organization are aghast at the suggestion that they run against our selfish natures. For that matter, everyone, regardless of politics, has to be appalled at people who impose costs on society in pursuit of their individual {162} interests -- hunting endangered species, polluting rivers, destroying historic sites to build shopping malls, spraying graffiti on public monuments, inventing weapons that elude metal detectors. Equally disturbing are the outcomes of actions that make sense to the individual choosing them but are costly to society when everyone chooses them. Examples include overfishing a harbor, overgrazing a commons, commuting on a bumper-to-bumper freeway, or buying a sport utility vehicle to protect oneself in a collision because everyone else is driving a sport utility vehicle. Many people dislike the suggestion that humans are inclined to selfishness because it would seem to imply that these self-defeating patterns of behavior are inevitable, or at least reducible only through p~ermanent coercive measures.
The fear of imperfectibility and the resultant embrace of the Blank Slate are rooted in a pair of fallacies. We have already met the naturalistic fallacy, the belief that whatever happens in nature is good. One might think that the belief was irreversibly tainted by Social Darwinism, but it was revived by the romanticism of the 1960s and 1970s. The
? environmentalist movement, in particular, often appeals to the goodness of nature to promote conservation of natural environments, despite their ubiquitous gore. For example, predators such as wolves, bears, and sharks have been given an image makeover as euthanists of the old and the lame, and thus worthy of preservation or reintroduction. It would seem to follow that anything we have inherited from this Eden is healthy and proper, so a claim that aggression or rape is "natural," in the sense of having been favored by evolution, is tantamount to saying that it is good.
The naturalistic fallacy leads quickly to its converse, the moralistic fallacy: that if a trait is moral, it must be found in nature. That is, not only does "is" imply "ought," but "ought" implies "is. " Nature, including human nature, is stipulated to have only virtuous traits (no needless killings, no rapacity, no exploitation), or no traits at all, because the alternative is too horrible to accept. That is why the naturalistic and moralistic fallacies are so often associated with the Noble Savage and the Blank Slate.
Defenders of the naturalistic and moralistic fallacies are not made of straw but include prominent scholars and writers. For example, in response to Thornhill's earlier writings on rape, the feminist scholar Susan Brownmiller wrote, "It seems quite clear that the biologicization of rape and the dismissal of social or 'moral' factors will . . . tend to legitimate rape. . . . It is reductive and reactionary to isolate rape from other forms of violent antisocial behavior and dignify it with adaptive significance. "6 Note the fallacy: if something is explained with biology, it has been "legitimated"; if something is shown to be adaptive, it has been "dignified. " Similarly, Stephen Jay Gould wrote of another discussion of rape in animals, "By falsely describing an inherited behavior in birds with an old name for a deviant human action, we subtly suggest that true {163} rape -- our own kind -- might be a natural behavior with Darwinian advantages to certain people as well. "7 The implicit rebuke is that to describe an act as "natural" or as having "Darwinian advantages" is somehow to condone it.
The moralistic fallacy, like the naturalistic fallacy, is, well, a fallacy, as we learn from this Arlo and Janis cartoon:
The boy has biology on his side. 8 George Williams, the revered evolutionary biologist, describes the natural world as "grossly immoral. "9 Having no foresight or compassion, natural selection "can honestly be described as a process for maximizing short-sighted selfishness. " On top of all the miseries inflicted by predators and parasites, the members of a species show no pity to their own kind. Infanticide, siblicide, and rape can be observed in many kinds of animals; infidelity is common even in so-called pair-bonded species; cannibalism can be expected in all species that are not strict vegetarians; death from fighting is more common in most animal species than it is in the most violent American cities. 10 Commenting on how biologists used to describe the killing of starving deer by mountain lions as an act of mercy, Williams wrote:
The simple facts are that both predation and starvation are painful prospects for deer, and that the lion's lot is no more enviable. Perhaps biology would have been able to mature more rapidly in a culture not dominated by Judeo-Christian theology and the Romantic tradition. It might have been well served by the First Holy Truth from [Buddha's] Sermon at Benares: "Birth is painful, old age is painful, sickness is painful, death is painful. . . "11
As soon as we recognize that there is nothing morally commendable about the products of evolution, we can describe human psychology honestly, without the fear that identifying a "natural" trait is the same as condoning it. As Katharine Hepburn says to Humphrey Bogart in The African Queen, "Nature, Mr. Allnut, is what we are put in this world to rise above. "
Crucially, this cuts both ways. Many commentators from the religious and cultural right believe that any behavior that strikes them as biologically {164} atypical, such as homosexuality, voluntary childlessness, and women who assume traditional male roles or vice versa, should be condemned because it is "unnatural. " For example, the popular talk-show host Laura Schlesinger has declared, "I am getting people to stop doing wrong and start doing right. " As part of this crusade she has called on gay people to submit to therapy to change their sexual orientation, because
? ? ? ? ? ? ? ? ? homosexuality is a "biological error. " This kind of moral reasoning can come only from people who know nothing about biology. Most activities that moral people extol -- being faithful to one's spouse, turning the other cheek, treating every child as precious, loving thy neighbor as thyself -- are "biological errors" and are utterly unnatural in the rest of the living world.
Acknowledging the naturalistic fallacy does not mean that facts about human nature are irrelevant to our choices. 12 The political scientist Roger Masters, noting that the naturalistic fallacy can be invoked too glibly to deny the relevance of biology to human affairs, points out, "When the physician says a patient ought to have an operation because the facts show appendicitis, the patient is unlikely to complain about a fallacious logical deduction. "13 Acknowledging the naturalistic fallacy implies only that discoveries about human nature do not, by themselves, dictate our choices. The facts must be combined with a statement of values and a method of resolving conflicts among them. Given the fact of appendicitis, the value that health is desirable, and the conviction that the pain and expense of the operation are outweighed by the resulting gain in health, one ought to have the operation.
Suppose rape is rooted in a feature of human nature, such as that men want sex across a wider range of circumstances than women do. It is also a feature of human nature, just as deeply rooted in our evolution, that women want control over when and with whom they have sex. It is inherent to our value system that the interests of women should not be subordinated to those of men, and that control over one's body is a fundamental right that trumps other people's desires. So rape is not tolerated, regardless of any possible connection to the nature of men's sexuality. Note how this calculus requires a "deterministic" and "essentialist" claim about human nature: that women abhor being raped. Without that claim we would have no way to choose between trying to deter rape and trying to socialize women to accept it, which would be perfectly compatible with the supposedly progressive doctrine that we are malleable raw material.
In other cases, the best way to resolve a conflict is not as obvious. The psychologists Martin Daly and Margo Wilson have documented that stepparents are far more likely to abuse a child than are biological parents. The discovery was by no means banal: many parenting experts insist that the abusive stepparent is a myth originating in Cinderella stories and that parenting is a "role" that anyone can take on. Daly and Wilson had originally examined the abuse statistics to test a prediction from evolutionary psychology. 14 Parental love is selected over {165} evolutionary time because it compels parents to protect and nurture their children, who are likely to carry the genes giving rise to parental love. In any species in which someone else's offspring are likely to enter the family circle, selection will favor a tendency to prefer one's own, because in the cold reckoning of natural selection an investment in the unrelated children would go to waste. A parent's patience will tend to run out with stepchildren more quickly than with biological children, and in extreme cases this can lead to abuse.
Does all this mean that social service agencies should monitor stepparents more closely than biological parents? Not so fast. The vast majority of both kinds of parents never commit abuse, so putting stepparents under a cloud of suspicion would be unfair to millions of innocent people. As the legal scholar Owen Jones points out, the evolutionary analysis of stepparenting -- or of anything else -- has no automatic policy implications.
Rather, it delineates a tradeoff and forces us to choose an optimum along it. In this case, the tradeoff is between minimizing child abuse while stigmatizing stepparents, on one hand, and being maximally fair to stepparents while tolerating an increase in child abuse, on the other. 15 If we did not know that people are predisposed to lose patience with stepchildren faster than with biological children, we would implicitly choose one end of this tradeoff -- ignoring step- parenting as a risk factor altogether, and tolerating the extra cases of child abuse -- without even realizing it.
An understanding of human nature with all its weaknesses can enrich not just our policies but our personal lives. Families with stepchildren tend to be less happy and more fragile than families with biological children, largely because of tensions over how much time, patience, and money the stepparents should expend. Many stepparents, nonetheless, are kind and generous to a spouse's children, in part out of love for the spouse. Still, there is a difference between the instinctive love that parents automatically lavish on their own children and the deliberate kindness and generosity that wise stepparents extend to their stepchildren. Understanding this difference, Daly and Wilson suggest, could enhance a marriage. 16 Though a marriage based on strict tit-for-tat reciprocity is generally miserable, a good marriage finds each spouse appreciating the sacrifices that the other has made over the long haul. Acknowledging a partner's conscious benevolence toward one's children may ultimately breed less resentment and misunderstanding than demanding such benevolence as a matter of course and begrudging any ambivalence the partner may feel. It is one of many ways in which a realism about the imperfect emotions we actually have may bring more happiness than an illusion about the ideal emotions we wish we had. ~
So if we are put in this world to rise above nature, how do we do it? Where in the causal chain of evolved genes building a neural computer do we find a {166} chink into which we can fit the seemingly unmechanical event of
? ? ? ? ? ? ? "choosing values"? By allowing for choice, are we just inviting a ghost back into the machine?
The question is itself a symptom of the Blank Slate. If one starts off thinking the slate is blank, then when someone proposes an innate desire one will mentally plunk it onto the barren surface in one's imagination and conclude that it must be an ineluctable urge, because there is nothing else on the slate to counteract it. Selfish thoughts translate into selfish behavior, aggressive urges beget natural-born killers, a taste for multiple sexual partners means that men just can't help fooling around. For example, when the primatologist Michael Ghiglieri appeared on the National Public Radio program Science Friday to talk about his book on violence, the interviewer asked, "You explain rape and murder and war and all the bad things that men do as something -- if I would just boil it down -- something they can't help because of its -- it's locked up in their evolutionary genes there? "17
If, however, the mind is a system with many parts, then an innate desire is just one component among others. Some faculties may endow us with greed or lust or malice, but others may endow us with sympathy, foresight, selfrespect, a desire for respect from others, and an ability to learn from our own experiences and those of our neighbors. These are physical circuits residing in the prefrontal cortex and other parts of the brain, not occult powers of a poltergeist, and they have a genetic basis and an evolutionary history no less than the primal urges. It is only the Blank Slate and the Ghost in the Machine that make people think that drives are "biological" but that thinking and decision making are something else.
The faculties underlying empathy, foresight, and self-respect are information-processing systems that accept input and commandeer other parts of the brain and body. They are combinatorial systems, like the mental grammar underlying language, capable of cranking out an unlimited number of ideas and courses of action. Personal and social change can come about when people exchange information that affects those mechanisms -- even if we are nothing but meat puppets, glorified clockwork, or lumbering robots created by selfish genes.
Not only is acknowledging human nature compatible with social and moral progress, but it can help explain the obvious progress that has taken place over millennia. Customs that were common throughout history and prehistory -- slavery, punishment by mutilation, execution by torture, genocide for convenience, endless blood feuds, the summary killing of strangers, rape as the spoils of war, infanticide as a form of birth control, and the legal ownership of women -- have vanished from large parts of the world.
The philosopher Peter Singer has shown how continuous moral progress can emerge from a fixed moral sense. 18 Suppose we are endowed with a {167} conscience that treats other persons as targets of sympathy and inhibits us from harming or exploiting them. Suppose, too, that we have a mechanism for assessing whether a living thing gets
to be classified as a person. (After all, we don't want to classify plants as persons and starve before we would eat them. ) Singer explains moral improvement in the title of his book: The Expanding Circle. People have steadily expanded the mental dotted line that embraces the entities considered worthy of moral consideration. The circle has been poked outward from the family and village to the clan, the tribe, the nation, the race, and most recently (as in the Universal Declaration of Human Rights) to all of humanity. It has been slackened from royalty, aristocracy, and property holders to all men. It has grown from including only men to including women, children, and newborns. It has crept outward to embrace criminals, prisoners of war, enemy civilians, the dying, and the mentally handicapped. Nor are the possibilities for moral progress over. Today some people want to enlarge the circle to include great apes, warm-blooded creatures, or animals with central nervous systems. Some want to count in zygotes, blastocysts, fetuses, and the brain-dead. Still others want to embrace species, ecosystems, or the entire planet. This sweeping change in sensibilities, the driving force in the moral history of our species, did not require a blank slate or a ghost in the machine. It could have arisen from a moral gadget containing a single knob or slider that adjusts the size of the circle embracing the entities whose interests we treat as comparable to our own.
The expansion of the moral circle does not have to be powered by some mysterious drive toward goodness. It may come from the interaction between the selfish process of evolution and a law of complex systems. The biologists
John Maynard Smith and Eors Szathmary and the journalist Robert Wright have explained how evolution can lead to greater and greater degrees of cooperation. 19 Repeatedly in the history of life, replicators have teamed up, specialized to divide the labor, and coordinated their behavior. It happens because replicators often find themselves in non-zero- sum games, in which particular strategies adopted by two players can leave them both better off (as opposed to a zero- sum game, where one player's profit is another player's loss). An exact analogy is found in the play by William Butler Yeats in which a blind man carries a lame man on his shoulders, allowing both of them to get around. During the evolution of life this dynamic has led replicating molecules to team up in chromosomes, organelles to team up in cells, cells to agglomerate into complex organisms, and organisms to hang out in societies. Independent agents repeatedly made their fate hostage to a larger system, not because they are inherently civic-minded but because they benefited from the division of labor and developed ways of damping conflicts among the agents making up the system.
Human societies, like living things, have become more complicated and cooperative over time. Again, it is because
? ? ? ? agents do better when they team up {168} and specialize in pursuit of their shared interests, as long as they solve the problems of exchanging information and punishing cheaters. If I have more fruit than I can eat and you have more meat than you can eat, it pays each of us to trade our surplus with the other. If we face a common enemy, then, as Benjamin Franklin put it, "We must all hang together, or assuredly we shall all hang separately. "
Wright argues that three features of human nature led to a steady expansion of the circle of human cooperators. One is the cognitive wherewithal to figure out how the world works. This yields know-how worth sharing and an ability to spread goods and information over larger territories, both of which expand opportunities for gains in trade. A second is language, which allows technology to be shared, bargains to be struck, and agreements to be enforced. A third is an emotional repertoire -- sympathy, trust, guilt, anger, self-esteem -- that impels us to seek new cooperators, maintain relationships with them, and safeguard the relationships against possible exploitation. Long ago these endowments put our species on a moral escalator. Our mental circle of respect-worthy persons expanded in tandem with our physical circle of allies and trading partners. As technology accumulates and people in more parts of the planet become interdependent, the hatred between them tends to decrease, for the simple reason that you can't kill someone and trade with him too.
Non-zero-sum games arise not just from people's ability to help one another but from their ability to refrain from hurting one another. In many disputes, both sides come out ahead by dividing up the savings made available from not having to fight. That provides an incentive to develop technologies of conflict resolution, such as mediation, face- saving measures, measured restitution and retribution, and legal codes. The primatologist Frans de Waal has argued that the rudiments of conflict resolution may be found in many species of primates. 20 The human forms are ubiquitous across cultures, as universal as the conflicts of interest they are designed to defuse. 21
Though the evolution of the expanding circle (its ultimate cause) may sound pragmatic or even cynical, the psychology of the expanding circle (its proximate cause) need not be. Once the sympathy knob is in place, having evolved to enjoy the benefits of cooperation and exchange, it can be cranked up by new kinds of information that other folks are similar to oneself. Words and images from erstwhile enemies can trigger the sympathy response. A historical record can warn against self-defeating cycles of vendetta. A cosmopolitan awareness may lead people to think, "There but for fortune go I. " An expansion of sympathy may come from something as basic as the requirement to be logically consistent when imploring other people to behave in certain ways: people come to realize that they cannot force others to abide by rules that they themselves flout. Egoistic, sexist, racist, and xenophobic attitudes are logically {169} inconsistent with the demand that everyone respect a single code of behavior. 22 Peaceful coexistence, then, does not have to come from pounding selfish desires out of people. It can come from pitting some desires -- the desire for safety, the benefits of cooperation, the ability to formulate and recognize universal codes of behavior -- against the desire for immediate gain. These are just a few of the ways in which moral and social progress can ratchet upwards, not in spite of a fixed human~nature but because of it.
When you stop to think about it, the idea of a pliant human nature does not deserve its reputation for optimism and uplift. If it did, B. F. Skinner would have been lauded as a great humanitarian when he argued that society should apply the technology of conditioning to humans, shaping people to use contraception, conserve energy, make peace, and avoid crowded cities. 23 Skinner was a staunch blank-slater and a passionate Utopian. His uncommonly pure vision allows us to examine the implications of the "optimistic" denial of human nature. Given his premise that undesirable behavior is not in the genes but a product of the environment, it follows that we should control that environment -- for all we would be doing is replacing haphazard schedules of reinforcement by planned ones.
Why are most people repelled by this vision? Critics of Skinner's Beyond Freedom and Dignity pointed out that no one doubts that behavior can be controlled; putting a gun to someone's head or threatening him with torture are time- honored techniques. 24 Even Skinner's preferred method of operant conditioning required starving the organism to 80 percent of its free-feeding weight and confining it to a box where schedules of reinforcement were carefully controlled. The issue is not whether we can change human behavior, but at what cost.
Since we are not just products of our environments, there will be costs. People have inherent desires such as comfort, love, family, esteem, autonomy, aesthetics, and self-expression, regardless of their history of reinforcement, and they suffer when the freedom to exercise the desires is thwarted. Indeed, it is difficult to define psychological pain without some notion of human nature. (Even the young Marx appealed to a "species character," with an impulse for creative activity, as the basis for his theory of alienation. ) Sometimes we may choose to impose suffering to control behavior, as when we punish people who cause avoidable suffering in others. But we cannot pretend that we can reshape behavior without infringing in some way on other people's freedom and happiness. Human nature is the reason we do not surrender our freedom to behavioral engineers.
Inborn human desires are a nuisance to those with Utopian and totalitarian visions, which often amount to the same
? ? ? ? ? ? ? thing. What stands in the way of {170} most Utopias is not pestilence and drought but human behavior. So Utopians have to think of ways to control behavior, and when propaganda doesn't do the trick, more emphatic techniques are tried. The Marxist Utopians of the twentieth century, as we saw, needed a tabula rasa free of selfishness and family ties and used totalitarian measures to scrape the tablets clean or start over with new ones. As Bertolt Brecht said of the East German government, "If the people did not do better the government would dismiss the people and elect a new one. " Political philosophers and historians who have recently "reflected on our ravaged century," such as Isaiah Berlin, Kenneth Minogue, Robert Conquest, Jonathan Glover, James Scott, and Daniel Chirot, have pointed to Utopian dreams as a major cause of twentieth-century nightmares. 25 For that matter, Wordsworth's revolutionary France, "thrilled with joy" while human nature was "born again," turned out to be no picnic either.
It's not just behaviorists and Stalinists who forgot that a denial of human nature may have costs in freedom and happiness. Twentieth-century Marxism was part of a larger intellectual current that has been called Authoritarian High Modernism: the conceit that planners could redesign society from the top down using "scientific" principles. 26 The architect Le Corbusier, for example, argued that urban planners should not be fettered by traditions and tastes, since they only perpetuated the overcrowded chaos of the cities of his day. "We must build places where mankind will be reborn," he wrote. "Each man will live in an ordered relation to the whole. "27 In Le Corbusier's Utopia, planners would begin with a "clean tablecloth" (sound familiar? ) and mastermind all buildings and public spaces to service "human needs. " They had a minimalist conception of those needs: each person was thought to require a fixed amount of air, heat, light, and space for eating, sleeping, working, commuting, and a few other activities. It did not occur to Le Corbusier that intimate gatherings with family and friends might be a human need, so he proposed large communal dining halls to replace kitchens. Also missing from his list of needs was the desire to socialize in small groups in public places, so he planned his cities around freeways, large buildings, and vast open plazas, with no squares or crossroads in which people would feel comfortable hanging out to schmooze. Homes were "machines for living," free of archaic inefficiencies like gardens and ornamentation, and thus were efficiently packed together in large, rectangular housing projects.
Le Corbusier was frustrated in his aspiration to flatten Paris, Buenos Aires, and Rio de Janeiro and rebuild them according to his scientific principles. But in the 1950s he was given carte blanche to design Chandigarh, the capital of the Punjab, and one of his disciples was given a clean tablecloth for Brasilia, the capital of Brazil. Today, both cities are notorious as uninviting wastelands detested by the civil servants who live in them. Authoritarian High Modernism also led to the "urban renewal" projects in many American cities {171} during the 1960s that replaced vibrant neighborhoods with freeways, high-rises, and empty windswept plazas.
Social scientists, too, have sometimes gotten carried away with dreams of social engineering. The child psychiatrist Bruce Perry, concerned that ghetto mothers are not giving children the enriched environment needed by their plastic brains, believes we must "transform our culture": "We need to change ' our child rearing practices, we need to change the malignant and destructive view that children are the property of their biological parents. Human beings evolved not as individuals, but as communities. . . . Children belong to the community, they are entrusted to their parents. "28 Now, no one could object to rescuing children from neglect or cruelty, but if Perry's transformed culture came to pass, men with guns could break up any family that did not conform to the latest fad in parenting theory. As we will see in the chapter on children, most of these fads are based on flawed studies that treat every correlation between parents and children as proof of causation. Asian American and African American parents often flout the advice of the child-development gurus, using more traditional, authoritarian styles of childrearing that in all likelihood do their children no lasting harm. 29 The parenting police could strip them of their children.
Nothing in the concept of human nature is inconsistent with the ideals of feminism, or so I will argue in the chapter on gender. But some feminist theoreticians have embraced the Blank Slate and with it an authoritarian political philosophy that would give the government sweeping powers to implement their vision of gender-free minds. In a 1975 dialogue, Simone de Beauvoir said: "No woman should be authorized to stay at home to raise her children. Society should be totally different. Women should not have that choice, precisely because if there is such a choice, too many women will make that one. "30 Gloria Steinem was a bit more liberal; in a 1970 Time article she wrote: "The [feminist] revolution would not take away the option of being a housewife. A woman who prefers to be her husband's housekeeper and/or hostess would receive a percentage of his pay determined by the domestic-relations courts. "31 Betty Friedan has spoken out in favor of "compulsory preschool" for two-year-olds. 32 Catharine MacKinnon (who with Andrea Dworkin has pushed for laws against erotica) has said, "What you need is people who see through literature like Andrea Dworkin, who see through law like me, to see through art and create the uncompromised women's visual vocabulary"33 -- oblivious to the danger inherent in a few intellectuals' arrogating the role of deciding which art and literature the rest of society will enjoy.
In an interview in the New York Times Magazine, Carol Gilligan explained the implications of her (preposterous) theory that behavior problems in boys, such as stuttering and hyperactivity, are caused by cultural norms that
? ? ? ? ? ? ? ? ? ? ? pressure them to separate from their mothers: {172}
q: You would argue that men's biology is not so powerful that we can't change the culture of men? a: Right. We have to build a culture that doesn't reward that separation from the person who raised them. . . .
q: Everything you've said suggests that unless men change in fundamental ways, we're not going to have a sea change in the culture.
a: That seems right to me. 34
An incredulous reader, hearing an echo of the attempt to engineer a "new socialist man," asked, "Does anyone, even in academia, still believe that this sort of thing turns out well? "35 He was right to be concerned. In many schools,
teachers have been told, falsely, that there is an "opportunity zone" in which a child's gender identification is malleable. They have used this zone to try to stamp out boyhood: banning same-sex play groups and birthday parties, forcing children to do gender-atypical activities, suspending boys who run during recess or play cops and robbers. 36 In her book The War Against Boys, the philosopher Christina Hoff Sommers rightly calls this agenda "meddlesome, abusive, and quite beyond what educators in a free society are mandated to do. "37
Feminism, far from needing a blank slate, needs the opposite, a clear conception of human nature. One of the most pressing feminist causes today is the condition of women in the developing world. In many places female fetuses are selectively aborted, newborn girls are killed, daughters are malnourished and kept from school, adolescent girls have their genitals cut out, young women are cloaked from head to toe, adulteresses are stoned to death, and widows are expected to fall onto their husbands' funeral pyres. The relativist climate in many academic circles does not allow these horrors to be criticized because they are practices of other cultures, and cultures are superorganisms that, like people, have inalienable rights. To escape this trap, the feminist philosopher Martha Nussbaum has invoked "central functional capabilities" that all humans have a right to exercise, such as physical integrity, liberty of conscience, and political participation. She has been criticized in turn for taking on a colonial "civilizing mission" or "white woman's burden," in which arrogant Europeans would instruct the poor people of the world in what they want. But Nussbaum's moral argument is defensible if her "capabilities" are grounded, directly or indirectly, in a universal human nature. Human nature provides a yardstick to identify suffering in any member of our species.
The existence of a human nature is not a reactionary doctrine that dooms us to eternal oppression, violence, and greed. Of course we should try to reduce harmful behavior, just as we try to reduce afflictions like hunger, disease, and {173} the elements. But we fight those afflictions not by denying the pesky facts of nature but by turning some of them against the others. For efforts at social change to be effective, they must identify the cognitive and moral resources that make some kinds of change possible. And for the efforts to be humane, they must acknowledge the universal pleasures and pains that make some kinds of change desirable.

The Fear of Determinism
This chapter is not about the boo-word that is frequently (and inaccurately) hurled at any explanation of a behavioral tendency that mentions evolution or genetics. It is about determinism in its original sense, the concept that is opposed to "free will" in introductory philosophy courses. The fear of determinism in this sense is captured in a limerick:
There was a young man who said: "Damn! It grieves me to think that I am Predestined to move
In a circumscribed groove:
In fact, not a bus, but a tram. "
In the traditional conception of a ghost in the machine, our bodies are inhabited by a self or a soul that chooses the behavior to be executed by the body. These choices are not compelled by some prior physical event, like one billiard ball smacking into another and sending it into a corner pocket. The idea that our behavior is caused by the physiological activity of a genetically shaped brain would seem to refute the traditional view. It would make our behavior an automatic consequence of molecules in motion and leave no room for an uncaused behavior-chooser.
