In this book, Phillips gives an overview of the contribution of Nyaya--the classical Indian school that defends an externalist position about knowledge as well as an internalist position about justification. Nyaya literature extends almost two thousand years and comprises hundreds of texts, and in this book, Phillips presents a useful overview of the under-studied system of thought. For the philosopher rather than the scholar of Sanskrit, the book makes a whole range of Nyaya positions and arguments accessible to students of epistemology who are unfamiliar with classical Indian systems.
