Book excerpt: The tradition of ancient philosophy is a long, rich and varied one, in which a constant note is that of discussion and argument. This book introduces readers to some ancient debates to engage with the ancient developments of some themes. Getting away from the presentation of ancient philosophy as a succession of Great Thinkers, the book gives readers a sense of the freshness and liveliness of ancient philosophy, and of its wide variety of themes and styles.
