The insistence on deprecating the efficacy of socialization leads Pinker into absurdities that he handles with a blitheness that would be charming if his self-assurance were not so overdeveloped. He argues, for example, that democracy, the rule of law, and women’s reproductive freedom are all products of evolution. The Founding Fathers understood that the ideas of power sharing and individual rights are grounded in human nature. And he quotes, with approval, the claim of two evolutionary psychologists that the “evolutionary calculus” explains why women evolved “to exert control over their own sexuality, over the terms of their relationships, and over the choice of which men are to be the fathers of their children.” Now, democracy, individual rights, and women’s sexual autonomy are concepts almost nowhere to be found, even in the West, before the eighteenth century. Either human beings spent ten thousand years denying their own nature by slavishly obeying the whims of the rich and the powerful, cheerfully burning heretics at the stake, and arranging their daughters’ marriages (which would imply a pretty effective system of socialization), or modern liberal society is largely a social construction. Which hypothesis seems more plausible?

[…E]ver since On the Origin of Species and The Descent of Man, people have used Darwin’s theory to explain why one or another way of managing human affairs is “natural”. The notion is that a particular arrangement must have been “selected for”—as though the struggle among individuals and groups were nature’s way of making sure that we end up with the best. Evolutionary psychology is therefore a philosophy for winners: it can be used to justify every outcome. This is why Pinker has persuaded himself that liberal democracy and current opinion about women’s sexual autonomy have biological foundations. It’s a “scientific” validation of the way we live now. But every aspect of life has a biological foundation in exactly the same sense, which is that unless it was biologically possible it wouldn’t exist. After that, it’s up for grabs.
