"Zagzebski's book brims with acute observations and is written in such a way that even those not trained in analytic philosophy will find it an enjoyable read. Her focus on the virtues leads her to avoid a style of philosphy that endlessly h=generates counterexamples and engages in barren possible-worlds speculation. Zagzebski brings the resources of premodern philosophy to bear on contemporary issues and opens up a line of inquiry that could prove as fruitful for epistemology as it already has for ethics. Throughout the book, she notes that this is a large project and invites the assistance of others. It is an invitation Thomists would do well to accept." Thomas S. Hibbs, The Thomist

"The book is clearly written and highly original, and it reveals an impressive familiarity with sources both classical and contemporary. It should be in every university library." H. Pospesel, Choice

"...it is hard to imagine anyone leaving this book without having been moved to new reflections upon epistemological and ethical issue." Douglas J. Den Uyl, Review of Metaphysics
