"Philippa Foot has for many years been one of the most distinctive and influential thinkers in moral philosophy. Long dissatisfied with the moral theories of her contemporaries, she has gradually evolved a theory of her own that is radically opposed not only to emotivism and prescriptivism but also to the whole subjectivist, anti-naturalist movement deriving from David Hume. Dissatisfied also with both Kantian and utilitarian ethics, she claims to have isolated a special form of evaluation that predicates goodness and defect only to living things considered as such: she finds this form of evaluation in moral judgements. Her vivid discussion ranges over topics such as practical rationality, erring conscience, and the relation between virtue and happiness, ending with a critique of Nietzsche's immoralism. This work is an exposition of an approach to moral philosophy, which represents a fundamental break away from the assumptions of previous debates."--BOOK JACKET.
