Publisher’s Note: This collection of essays, written between 1957 and 1977, contains discussions of the moral philosophy of David Hume, Immanuel Kant, Friedrich Nietzsche, and some modern philosophers. It presents virtues and vices rather than rights and duties as the central concepts in moral philosophy. Throughout, the author rejects contemporary anti? naturalistic moral philosophies such as emotivism and prescriptivism, but defends the view that moral judgements may be hypothetical rather than (as Kant thought) categorical imperatives. The author also applies her moral philosophy to the current debates on euthanasia and abortion, the latter discussed in relation to the doctrine of the double effect. She argues against the suggestion, on the part of A. J. Ayer and others, that free will actually requires determinism. In a final essay, she asks whether the concept of moral approval can be understood except against a particular background of social practices.

Comment: Foot stands out among contemporary ethical theorists because of her conviction that virtues and vices are more central ethical notions than rights, duties, justice, or consequences. Since the author discusses multiple relevant topics (abortion, euthanasia, free will/determination, and the ethics of Hume and Nietzsche) this book is a really complete reading for Ethics courses. The book can be used in both, undergraduate and postgraduate courses, but the last eight essays are more suitable for postgraduates.

Abstract: Sidgwick argued that utilitarianism was not rationally required because it could not be shown that a utilitarian theory of practical reason was better justified than a rival egoist theory of practical reason: there is a ‘dualism of practical reason’ between utilitarianism and egoism. In this paper, it is demonstrated that the dualism argument also applies to Kant’s moral theory, the moral law. A prudential theory that is parallel to the moral law is devised, and it is argued that the moral law is no better justified than this prudential theory. So the moral law is not rationally required. It is suggested that the dualism argument is a completely general argument that ethics cannot be rationally required.

Comment: This is a good and fairly accessible argument that casts doubt on the project of deriving morality from reason. It can be used alongside Kantian approaches to metaethics or reasons constituvism.
