Popkin and Stroll review each major theory of philosophy chronologically, and then further organise these theories into their respective subject areas: metaphysics, epistemology, ethics, political philosophy, and philosophy of religion. Within each subject area, the authors discuss how the sceptical challenge gave rise to new philosophical positions. The volume concludes with an especially interesting debate between the authors on the merits of scepticism today. Stroll thinks that, ultimately, the doubts expressed by sceptics can be refuted, while Popkin denies this. This is an outstanding introduction to the problems of philosophy by two eminent philosophers with a gift for presenting the history of ideas in a very enjoyable fashion.
