R. M. Hare has brought together in this volume the best of his uncollected essays in moral philosophy, several of them previously unpublished or revised for this collection. They span the whole range of his ethical interests, from the most abstract to the most down-to-earth. The reader will find here the bases of his ethical theory in Kantian prescriptivism, utilitarianism, and the logic of imperatives, and will see that theory applied to issues of bioethics, medical ethics, business ethics, loyalty and obedience, and racism. The essays display the author's characteristic clarity and vigour; some of them are polemical, targeting particular opponents and rival theories. The volume provides a compelling demonstration of Hare's commitment to bringing together the theoretical and the practical in ethics.
