How ought we to live? What really exists? How do we know? This Very Short Introduction discusses some of the key questions philosophy engages with. Edward Craig explores important themes in ethics, and the nature of knowledge and the self, through readings from Plato, Hume, Descartes, Hegel,
Darwin, and Buddhist writers. Throughout, he emphasizes why we do phiilosophy, explains how different areas of philosophy are related, and explores the contexts in which philosophy was and is done.

This new edition includes a new chapter on free will, discussing determinism and indeterminism in the context of Descartes and Hegel's work. Craig also covers the Problem of Evil, and Kant's argument on the source of moral obligation.
