Adopting a historical approach to moral philosophy, this clear introductory text discusses in chronological sequence the theories of major ethical philosophers. Norman redraws traditional boundaries to include not only Plato, Aristotle, Hume, Kant, and Mill, but also Hegelian ethics and the contributions of Marx and Freud to our understanding of the nature and limits of morality. Intended for undergraduates, the book is structured for use as a basic text in introductory courses on ethics.
