Despite the problems students often have with the theory of knowledge, it remains, necessarily, at the core of the philosophical enterprise. As experienced teachers know, teaching epistemology requires a text that is not only clear and accessible, but also capable of successfully motivating the abstract problems that arise. In Knowledge Puzzles, Stephen Hetherington presents an informal survey of epistemology based on the use of puzzles to illuminate problems of knowledge. Each topic is introduced through a puzzle, and readers are invited to work their own ways toward a solution. Hetheringtons light and undogmatic style encourages class discussion and independent thought rather than the memorization of book answers. Covering all of the most important epistemological issues, informed by classical and contemporary literature, and rich in probing questions and suggestions for further readings, Knowledge Puzzles is a pedagogical breakthrough. Whether it is used as a main text or supplement, this lucid and engaging text will be welcomed by both teachers and students.
