"Matthew Dasti and Stephen Phillips have done the philosophical world, and teachers and students of philosophy, a great favor in presenting this superb translation of major portions of the Nyāya-sūtra with selections from its most important commentaries. This text is central to the history of Indian epistemology and metaphysics, and was influential well beyond the world of Nyāya, and its most important philosophical passages are presented here. Dasti and Phillips’ translations of this often-technical text are fluent and clear, rendering it in accessible but precise philosophical English. Their explanatory notes are clear, accurate, and concise. The inclusion of substantial extracts of the commentaries of Vātsyāyana, Vācaspatimiśra, and Uddyotakara is especially welcome. Not only do these masterful commentaries extend and explain the philosophical ideas in the sūtra, but they demonstrate to the reader the importance of reading this text through the commentarial tradition it inspires and the vitality of that tradition. This will be a valuable resource to scholars as well as to teachers and students." —Jay Garfield, Professor of Philosophy, Smith College
