The second edition of this distinguished and popular Companion introduces new chapters on the philosophy of biology; bioethics, genethics, and medical ethics; environmental ethics; business ethics; ethnicity, culture and philosophy; Plato and Aristotle; medieval philosophy; Francis Bacon; Nietzsche; Husserl and Heidegger; and Sartre, Foucault and Derrida. It also revises several existing chapters to extend its comprehensive and authoritative exploration of the issues, controversies and problems that arise from the study of philosophy.

The Companion functions primarily as a flexible and distinctive introductory textbook, but even advanced students will welcome its stimulating and accessible chapters and the guidance provided by cross-references, glossary entries, boxed highlights, bibliographies, discussion questions, and further reading.
