Title: Highly recommended companion to Pirsig's book
Review: Additional background material, both philosophical and historical, really illuminates the original Pirsig book. The bonus is sometimes startling insights, and new questions (often unanswered for the reader to work out). Think of it as an informal but well-written textbook by teachers who care both about the material and the student. It lures the reader into further self-study in epistemology, metaphysics, aesthetics, and ethics. Contains valuable passages that were edited out of the original Pirsig book.
