This, the third Volume in this Encyclopedia to deal with Buddhist philosophy, takes the reader from the middle of the sixth. Many of the authors and texts treated here are not well known to the casual student of Buddhism. The most important author is clearly Dignaga, who is almost entirely responsible for turning Indian Buddhism toward an exhaustive analysis of epistemic considerations and in particular of inferential reasoning. But other author whose works are summarized here deserve to be better known, in particular the rival Yogacara commentors Buddhapalita and Bhavya, the latter of whom in particular introduces for the first time into Buddhism contrasts between the viewpoint of his particular brand of Buddhism and all the other system of contemporary India, and not just the Buddhists.
