Nature, reason, and the good life

At the centre of our ethical thought stands the human being. Facts about human nature determine the shape of ethical concepts in a variety of ways, and our pre-rational animal nature forms the basis of notions to do with rationality, virtue, and happiness, among other things. Nature, Reason, and the Good Life examines these themes while also arguing for the critical importance of language: only by attending to the social and empirical character of actual language use can we make headway with a number of problems in ethics. Thus what counts as a good or bad reason for action depends on the purposes of human enquiry, as embodied in the question "Why?" - it does not depend, for example, on some abstract and higher Rationality connected with "the point of the cosmos". Furthermore, considerations in philosophy of language and in philosophy of mind together show how emotions, desires, and pleasure - all crucial for ethics - turn out not to be inner states carrying a sort of subjective authority, above or below criticism or justification, and this fact helps undermine various forms of subjectivism and individualism to be found both in philosophy and in the wider culture.
