Jñanasrimitra
Jñānaśrīmitra (fl. 975-1025 C.E.) was an Indian Buddhist philosopher of the epistemological ("pramana") tradition of Buddhist philosophy, which goes back to Dignaga and Dharmakirti. He was also a poet, a "dvarapandita" (gate-scholar) of Vikramasila and was the teacher of Ratnakīrti. Jñānaśrīmitra was well known by Hindu and Jain thinkers and was the most significant Buddhist figure of his era. Thought. Jñanasrimitra's philosophical work focused on Buddhist logic and epistemology ("pramana"), especially the theory of "exclusion" ("apoha") outlined by Dignaga and how it relates to the philosophy of language, meaning and the nature of conceptual thoughts and  awareness. In his "Apohaprakaraṇa" (“Monograph on Exclusion”), Jñanasrimitra elaborates on the theory of "apoha" and its relation to epistemology as well as defending the theory from Hindu critics. Jñanasrimitra was also a defender of Yogācāra idealism, writing that “this entire triple-world is established to be nothing but consciousness ("vijñaptimātra")." Jñanasrimitra's "Vyāpticarcā" (Analysis of Pervasion) focuses on inferential relations termed "vyapti" (pervasion), the relations between two distinct entities such as smoke and fire. According to Horst Lasic, Jñanasrimitra's position on this topic is that "inference-warranting relations between two distinct entities must be effect-cause relations, and that  the presence of such relations can be detected only through a specific sequence of perception and non-apprehension." Jñānaśrīmitra was also known as the major defender of the Sākāra school of Yogācāra Buddhism against Ratnākaraśānti, the principal defender of the rival Nirākāra school. He also wrote a treatise against the Hindu creator God ("Isvara").
