This collection is organized into sections, intended to provide instructors with flexibility in designing and teaching a variety of courses in moral philosophy. Opening with Alasdair MacIntyre's discussion of the importance of the history of ethics, the first section, Historical Sources, moves from classical thought (Plato, Aristotle, Epicurus and Epictetus) through medieval views (Augustine and Aquinas) to modern theories (Hobbes, Butler, Hume, Kant, Bentham and Mill). It culminates with the religiosity of Kierkegaard, the pessimism of Schopenhauer, the nihilism of Nietzsche, the pragmatism of James and Dewey, and the existentialism of Camus and Sartre. The readings are reprinted in their entirety wherever possible. The second section of the text, Modern Ethical Theory, begins with James Rachels' overview of recent developments and includes many important essays of the 20th century. The discussion of utilitarianism, Kantianism, egoism, and relativism continues in the work of major contemporary philosophers (Williams, Brandt, Feinberg, Foot and Rachels). This book is intended for students taking introductory ethics and moral philosophy courses.
