The Blank Slate: The Modern Denial of Human Nature

by Steven Pinker

  In the economic or social contract tradition, society is an arrangement negotiated by rational, self-interested individuals. Society emerges when people agree to sacrifice some of their autonomy in exchange for security from the depredations of others wielding their autonomy. It is the tradition of Thrasy-machus in Plato’s Republic, and of Machiavelli, Hobbes, Locke, Rousseau, Smith, and Bentham. In the twentieth century it became the basis for the rational actor or “economic man” models in economics and political science, and for cost-benefit analyses of public choices.

  The modern theory of evolution falls smack into the social contract tradition. It maintains that complex adaptations, including behavioral strategies, evolved to benefit the individual (indeed, the genes for those traits within an individual), not the community, species, or ecosystem.6 Social organization evolves when the long-term benefits to the individual outweigh the immediate costs. Darwin was influenced by Adam Smith, and many of his successors analyze the evolution of sociality using tools that come right out of economics, such as game theory and other optimization techniques.

  Reciprocal altruism, in particular, is just the traditional concept of the social contract restated in biological terms. Of course, humans were never solitary (as Rousseau and Hobbes incorrectly surmised), and they did not inaugurate group living by haggling over a contract at a particular time and place. Bands, clans, tribes, and other social groups are central to human existence and have been so for as long as we have been a species. But the logic of social contracts may have propelled the evolution of the mental faculties that keep us in these groups. Social arrangements are evolutionarily contingent, arising when the benefits of group living exceed the costs.7 With a slightly different ecosystem and evolutionary history, we could have ended up like our cousins the orangutans, who are almost entirely solitary. And according to evolutionary biology, all societies—animal and human—seethe with conflicts of interest and are held together by shifting mixtures of dominance and cooperation.

  Throughout the book we have seen how the sciences of human nature have clashed with the sociological tradition. The social sciences were taken over by the doctrine that social facts live in their own universe, separate from the universe of individual minds. In Chapter 4 we saw an alternative conception in which cultures and societies arise from individual people pooling their discoveries and negotiating the tacit agreements that underlie social reality. We saw how a departure from the sociological paradigm was a major heresy of Wilson’s Sociobiology, and that the primacy of society was a foundation of Marxism and played a role in its disdain for the interests of individual people.

  The division between the sociological and economic traditions is aligned with the division between the political left and the political right, but only roughly. Marxism is obviously in the sociological tradition, and free-market conservatism is obviously in the economic tradition. In the liberal 1960s, Lyndon Johnson wanted to forge a Great Society, Pierre Trudeau a Just Society. In the conservative 1980s, Margaret Thatcher said, “There is no such thing as society. There are individual men and women, and there are families.”

  But as Masters points out, Durkheim and Parsons were in the sociological tradition, yet they were conservatives. One can easily see how conservative beliefs can favor the preservation of society as an entity and thereby downplay the desires of individuals. Conversely, Locke was in the social contract tradition, but he is a patron saint of liberalism, and Rousseau, who coined the expression “social contract,” was an inspiration for liberal and revolutionary thinkers. Social contracts, like any contract, can become unfair to some of the signatories, and may have to be renegotiated progressively or redrawn from scratch in a revolution.

  So the clash between the sociological and economic traditions can explain some of the heat ignited by the sciences of human nature, but it is not identical to the firefight between the political left and the political right. The rest of the chapter will scrutinize that second and hotter button.

  THE RIGHT-LEFT AXIS aligns an astonishing collection of beliefs that at first glance seem to have nothing in common. If you learn that someone is in favor of a strong military, for example, it is a good bet that the person is also in favor of judicial restraint rather than judicial activism. If someone believes in the importance of religion, chances are she will be tough on crime and in favor of lower taxes. Proponents of a laissez-faire economic policy tend to value patriotism and the family, and they are more likely to be old than young, pragmatic than idealistic, censorious than permissive, meritocratic than egalitarian, gradualist than revolutionary, and in a business rather than a university or government agency. The opposing positions cluster just as reliably: if someone is sympathetic to rehabilitating offenders, or to affirmative action, or to generous welfare programs, or to a tolerance of homosexuality, chances are good that he will also be a pacifist, an environmentalist, an activist, an egalitarian, a secularist, and a professor or student.

  Why on earth should people’s beliefs about sex predict their beliefs about the size of the military? What does religion have to do with taxes? Whence the linkage between strict construction of the Constitution and disdain for shocking art? Before we can understand why beliefs about an innate human nature might cluster with liberal beliefs or with conservative beliefs, we have to understand why liberal beliefs cluster with other liberal beliefs and conservative beliefs cluster with other conservative beliefs.

  The meanings of the words are of no help. Marxists in the Soviet Union and its aftermath were called conservatives; Reagan and Thatcher were called revolutionaries. Liberals are liberal about sexual behavior but not about business practices; conservatives want to conserve communities and traditions, but they also favor the free market economy that subverts them. People who call themselves “classical liberals” are likely to be called “conservatives” by adherents of the version of leftism known as political correctness.

  Nor can most contemporary liberals and conservatives articulate the cores of their belief systems. Liberals think that conservatives are just amoral plutocrats, and conservatives think that if you are not a liberal before you are twenty you have no heart but if you are a liberal after you are twenty you have no brain (attributed variously to Georges Clemenceau, Dean Inge, Benjamin Disraeli, and Maurice Maeterlinck). Strategic alliances—such as the religious fundamentalists and free-market technocrats on the right, or the identity politicians and civil libertarians on the left—may frustrate the search for any intellectual common denominator. Everyday political debates, such as whether tax rates should be exactly what they are or a few points higher or lower, are just as uninformative.

  The most sweeping attempt to survey the underlying dimension is Thomas Sowell’s A Conflict of Visions.8 Not every ideological struggle fits his scheme, but as we say in social science, he has identified a factor that can account for a large proportion of the variance. Sowell explains two “visions” of the nature of human beings that were expressed in their purest forms by Edmund Burke (1729-1797), the patron of secular conservatism, and William Godwin (1756-1836), the British counterpart to Rousseau. In earlier times they might have been referred to as different visions of the perfectibility of man. Sowell calls them the Constrained Vision and the Unconstrained Vision; I will refer to them as the Tragic Vision (a term he uses in a later book) and the Utopian Vision.9

  In the Tragic Vision, humans are inherently limited in knowledge, wisdom, and virtue, and all social arrangements must acknowledge those limits. “Mortal things suit mortals best,” wrote Pindar; “from the crooked timber of humanity no truly straight thing can be made,” wrote Kant. The Tragic Vision is associated with Hobbes, Burke, Smith, Alexander Hamilton, James Madison, the jurist Oliver Wendell Holmes Jr., the economists Friedrich Hayek and Milton Friedman, the philosophers Isaiah Berlin and Karl Popper, and the legal scholar Richard Posner.

  In the Utopian Vision, psychological limitations are artifacts that come from our social arrangements, and we should not allow
them to restrict our gaze from what is possible in a better world. Its creed might be “Some people see things as they are and ask ‘why?’; I dream things that never were and ask ‘why not?’ “The quotation is often attributed to the icon of 1960s liberalism, Robert F. Kennedy, but it was originally penned by the Fabian socialist George Bernard Shaw (who also wrote, “There is nothing that can be changed more completely than human nature when the job is taken in hand early enough”).10 The Utopian Vision is also associated with Rousseau, Godwin, Condorcet, Thomas Paine, the jurist Earl Warren, the economist John Kenneth Galbraith, and to a lesser extent the political philosopher Ronald Dworkin.

  In the Tragic Vision, our moral sentiments, no matter how beneficent, overlie a deeper bedrock of selfishness. That selfishness is not the cruelty or aggression of the psychopath, but a concern for our well-being that is so much a part of our makeup that we seldom reflect on it and would waste our time lamenting it or trying to erase it. In his book The Theory of Moral Sentiments, Adam Smith remarked:

  Let us suppose that the great empire of China, with all its myriads of inhabitants, was suddenly swallowed up by an earthquake, and let us consider how a man of humanity in Europe, who had no sort of connection with that part of the world, would react upon receiving intelligence of this dreadful calamity. He would, I imagine, first of all express very strongly his sorrow for the misfortune of that unhappy people, he would make many melancholy reflections upon the precariousness of human life, and the vanity of all the labours of man, which could thus be annihilated in a moment. He would, too, perhaps, if he was a man of speculation, enter into many reasonings concerning the effects which this disaster might produce upon the commerce of Europe, and the trade and business of the world in general. And when all this fine philosophy was over, when all these humane sentiments had been once fairly expressed, he would pursue his business or his pleasure, take his repose or his diversion, with the same ease and tranquillity as if no such accident had happened. The most frivolous disaster which could befall himself would occasion a more real disturbance. If he was to lose his little finger tomorrow, he would not sleep to-night; but provided he never saw them, he would snore with the most profound security over the ruin of a hundred million of his brethren.11

  In the Tragic Vision, moreover, human nature has not changed. Traditions such as religion, the family, social customs, sexual mores, and political institutions are a distillation of time-tested techniques that let us work around the shortcomings of human nature. They are as applicable to humans today as they were when they developed, even if no one today can explain their rationale. However imperfect society may be, we should measure it against the cruelty and deprivation of the actual past, not the harmony and affluence of an imagined future. We are fortunate enough to live in a society that more or less works, and our first priority should be not to screw it up, because human nature always leaves us teetering on the brink of barbarism. And since no one is smart enough to predict the behavior of a single human being, let alone millions of them interacting in a society, we should distrust any formula for changing society from the top down, because it is likely to have unintended consequences that are worse than the problems it was designed to fix. The best we can hope for are incremental changes that are continuously adjusted according to feedback about the sum of their good and bad consequences. It also follows that we should not aim to solve social problems like crime or poverty, because in a world of competing individuals one person’s gain may be another person’s loss. The best we can do is trade off one cost against another. In Burke’s famous words, written in the aftermath of the French Revolution:

  [One] should approach to the faults of the state as to the wounds of a father, with pious awe and trembling solicitude. By this wise prejudice we are taught to look with horror on those children of their country who are prompt rashly to hack that aged parent in pieces, and put him into the kettle of magicians, in hopes that by their poisonous weeds, and wild incantations, they may regenerate the paternal constitution, and renovate their father’s life.12

  In the Utopian Vision, human nature changes with social circumstances, so traditional institutions have no inherent value. That was then, this is now. Traditions are the dead hand of the past, the attempt to rule from the grave. They must be stated explicitly so their rationale can be scrutinized and their moral status evaluated. And by that test, many traditions fail: the confinement of women to the home, the stigma against homosexuality and premarital sex, the superstitions of religion, the injustice of apartheid and segregation, the dangers of patriotism as exemplified in the mindless slogan “My country, right or wrong.” Practices such as absolute monarchy, slavery, war, and patriarchy once seemed inevitable but have disappeared or faded from many parts of the world through changes in institutions that were once thought to be rooted in human nature. Moreover, the existence of suffering and injustice presents us with an undeniable moral imperative. We don’t know what we can achieve until we try, and the alternative, resigning ourselves to these evils as the way of the world, is unconscionable. At Robert Kennedy’s funeral, his brother Edward quoted from one of his recent speeches:

  All of us will ultimately be judged and as the years pass we will surely judge ourselves, on the effort we have contributed to building a new world society and the extent to which our ideals and goals have shaped that effort.

  The future does not belong to those who are content with today, apathetic toward common problems and their fellow man alike, timid and fearful in the face of new ideas and bold projects. Rather it will belong to those who can blend vision, reason and courage in a personal commitment to the ideals and great enterprises of American Society.

  Our future may lie beyond our vision, but it is not completely beyond our control. It is the shaping impulse of America that neither fate nor nature nor the irresistible tides of history, but the work of our own hands, matched to reason and principle, will determine our destiny. There is pride in that, even arrogance, but there is also experience and truth. In any event, it is the only way we can live.13

  Those with the Tragic Vision are unmoved by ringing declarations attributed to the first-person plural we, our, and us. They are more likely to use the pronouns as the cartoon possum Pogo did: We have met the enemy, and he is us. We are all members of the same flawed species. Putting our moral vision into practice means imposing our will on others. The human lust for power and esteem, coupled with its vulnerability to self-deception and self-righteousness, makes that an invitation to a calamity, all the worse when that power is directed at a goal as quixotic as eradicating human self-interest. As the conservative philosopher Michael Oakshott wrote, “To try to do something which is inherently impossible is always a corrupting enterprise.”

  The two kinds of visionaries thereby line up on opposite sides of many issues that would seem to have little in common. The Utopian Vision seeks to articulate social goals and devise policies that target them directly: economic inequality is attacked in a war on poverty, pollution by environmental regulations, racial imbalances by preferences, carcinogens by bans on food additives. The Tragic Vision points to the self-interested motives of the people who would implement these policies—namely, the expansion of their bureaucratic fiefdoms—and to their ineptitude at anticipating the myriad consequences, especially when the social goals are pitted against millions of people pursuing their own interests. Thus, say the Tragic Visionaries, the Utopians fail to anticipate that welfare might encourage dependency, or that a restriction on one pollutant might force people to use another.

  Instead, the Tragic Vision looks to systems that produce desirable outcomes even when no member of the system is particularly wise or virtuous. Market economies, in this vision, accomplish that goal: remember Smith’s butcher, brewer, and baker providing us with dinner out of self-interest rather than benevolence. No mastermind has to understand the intricate flow of goods and services that make up an economy in order to anticipate who needs what, and when and where. Pr
operty rights give people an incentive to work and produce; contracts allow them to enjoy gains in trade. Prices convey information about scarcity and demand to producers and consumers, so they can react by following a few simple rules—make more of what is profitable, buy less of what is expensive—and the “invisible hand” will do the rest. The intelligence of the system is distributed across millions of not-necessarily-intelligent producers and consumers, and cannot be articulated by anyone in particular.

  People with the Utopian Vision point to market failures that can result from having a blind faith in free markets. They also call attention to the unjust distribution of wealth that tends to be produced by free markets. Opponents with the Tragic Vision argue that the notion of justice makes sense only when applied to human decisions within a framework of laws, not when applied to an abstraction called “society.” Friedrich Hayek wrote, “The manner in which the benefits and burdens are apportioned by the market mechanism would in many instances have to be regarded as very unjust if it were the result of a deliberate allocation to particular people.” But that concern with social justice rests on a confusion, he claimed, because “the particulars of [a spontaneous order] cannot be just or unjust.”14

  Some of today’s battles between left and right fall directly out of these different philosophies: big versus small government, high versus low taxes, protectionism versus free trade, measures that aim to reduce undesirable outcomes (poverty, inequality, racial imbalance) versus measures that merely level the playing field and enforce the rules. Other battles follow in a less obvious way from the opposing visions of human potential. The Tragic Vision stresses fiduciary duties, even when the person executing them cannot see their immediate value, because they allow imperfect beings who cannot be sure of their virtue or foresight to participate in a tested system. The Utopian Vision stresses social responsibility, where people hold their actions to a higher ethical standard. In Lawrence Kohlberg’s famous theory of moral development, a willingness to ignore rules in favor of abstract principles was literally identified as a “higher stage” (which, perhaps tellingly, most people never reach).
