This Oxford Reader seeks to introduce some of the main philosophical questions raised by the Greek and Roman philosophers of classical antiquity. Selections from the writings of ancient philosophers are interspersed with Terence Irwin's incisive commentary, and sometimes with contributions from modern philosophers expounding relevant philosophical positions or discussing particular aspects of classical philosophy. The arrangement of the book is thematic, rather than chronological, allowing the reader to focus on philosophical problems and ideas, but a general introduction places philosophers and schools within their historical context. Irwin brings together contributions which shaped debates about knowledge, freedom, ethics, politics, and religious belief - debates which continue to be contested today, 2500 years from their conception.
