In this interview, Peter Singer argues that evolutionary theory has much to say that the Left ought to listen to. He claims that Leftist utopianism has failed to take account of human nature and blames that naiveté for the corruption and authoritarian failures of socialist regimes; the discipline of evolutionary psychology, Singer feels, is the key to understanding this ‘human nature.’ “I think it would be true generally that anyone who has views about how society should end up will have a better chance to achieve that if they understand the Darwinian framework of human nature.” In particular, because it offers an explanatory framework for understanding the development of human reciprocity, evolutionary theory helps us understand the basis for any ethical theory on which changing society must be based. — The Philosopher’s Magazine [via Butterflies and Wheels]
