The Emotional Construction of Morals

Abstract

AbstractThis book argues that recent work in philosophy, neuroscience, and anthropology supports two radical hypotheses about the nature of morality: moral values are based on emotional responses, and these emotional responses are inculcated by culture, not hard-wired through natural selection. In the first half of the book, the hypothesis that morality has an emotional foundation is defended. Evidence from brain imaging, social psychology, and psychopathology suggest that, when we judge something to be right or wrong, we are merely expressing our emotions. The book claims that these emotions do not track objective features of reality; rather, the rightness and wrongness of an act consists in the fact that people are disposed to have certain emotions towards it. In the second half of the book, it turns to a defence of moral relativism. Moral facts depend on emotional responses, and emotional responses vary from culture to culture. The book surveys the anthropological record to establish moral variation, and draws on cultural history to show how attitudes toward practices such as cannibalism and marriage change over time. It also criticizes evidence from animal behaviour and child development that has been taken to support the claim that moral attitudes are hard-wired by natural selection. The book concludes that there is no single true morality, but also argues that some moral values are better than others; moral progress is possible.
