Theory of Knowledge

The theory of knowledge is a hard subject to begin learning; with terms like "justification," "acceptance," "foundationalism," and "externalism" flying around, the philosophical novice may easily get lost in the philosophical whirlwind. Because I read Lehrer's introductory effort painstakingly and carefully, it mitigated my difficulties with learning epistemology. In a subject containing such obscure terminology, Lehrer starts the reader off on the right foot; if the reader puts enough work in to understand his first chapter, he will have a good understanding of the language of the subject. His remaining chapters do as good a job as can be expected of taking the reader through the various problems that the discussion of different theories of knowledge. Lehrer tries to make it interesting by arguing for his own pet theory (a coherence theory supported by the trustworthiness principle), and his ploy does help the reader pay attention, though in his partisanship he doesn't always present the opposing argument fairly (as in the counterexamples to undefeated justification in chapter 7). On the whole, however, a valient effort and a worthwhile read for anyone interested in epistemology.

Lehrer provides one of the best introductions to epistemology. The book is well suited to advanced undergraduates, graduates and professional philosophers alike. More importantly, it is an improvement on his first edition -- some areas of argument and explication have been cleaned up, and he has added material on recent developments in the field (e.g. contextualism and virtue epistemology). Great book.
