Dharmakirti in the context of Sautrāntika

Buddhist logico-epistemology is a term used in Western scholarship to describe Buddhist systems of pramāṇa (epistemic tool, valid cognition) and hetu-vidya (reasoning, logic).

While the term may refer to various Buddhist systems and views on reasoning and epistemology, it is most often used to refer to the work of the "Epistemological school" (Sanskrit: Pramāṇa-vāda), i.e., the school of Dignaga and Dharmakirti which developed from the 5th through 7th centuries and remained the main system of Buddhist reasoning until the decline of Buddhism in India.

Tsongkhapa (Tibetan: ཙོང་ཁ་པ་, [tsoŋˈkʰapa], meaning: "the man from Tsongkha" or "the Man from Onion Valley", c. 1357–1419) was an influential Tibetan Buddhist monk, philosopher and tantric yogi, whose activities led to the formation of the Gelug school of Tibetan Buddhism.

His philosophical works are a grand synthesis of the Buddhist epistemological tradition of Dignāga and Dharmakīrti, the Cittamatra philosophy of the mind, and the madhyamaka philosophy of Nāgārjuna and Candrakīrti.

Dignāga (also known as Diṅnāga, c. 470/480 – c. 530/540 CE) was an Indian Buddhist philosopher and logician. He is credited as one of the Buddhist founders of Indian logic (hetu vidyā) and atomism. Dignāga's work laid the groundwork for the development of deductive logic in India and created the first system of Buddhist logic and epistemology (pramāṇa).

According to Georges B. Dreyfus, his philosophical school brought about an Indian "epistemological turn" and became the "standard formulation of Buddhist logic and epistemology in India and Tibet." Dignāga's thought influenced later Buddhist philosophers like Dharmakīrti and also Hindu thinkers of the Nyāya school. Dignāga's epistemology accepted only "perception" (pratyaksa) and "inference" (anumāṇa) as valid instruments of knowledge and introduced the widely influential theory of "exclusion" (apoha) to explain linguistic meaning. His work on language, inferential reasoning and perception were also widely influential among later Indian philosophers. According to Richard P. Hayes "some familiarity with Dinnaga's arguments and conclusions is indispensable for anyone who wishes to understand the historical development of Indian thought."

Acharya Haribhadra Suri was a Śvetāmbara mendicant Jain leader, philosopher, doxographer, and author. There are multiple contradictory dates assigned to his birth. According to tradition, he lived c. 459–529 CE. However, in 1919, a Jain monk named Jinvijay pointed out that given his familiarity with Dharmakirti, a more likely choice would be sometime after 650. In his writings, Haribhadra identifies himself as a student of Jinabhaṭasūri of the Vidyadhara Kula. There are several, somewhat contradictory, accounts of his life. He wrote several books on Yoga, such as the Yogadṛṣṭisamuccaya and on comparative religion, outlining and analyzing the theories of Hindus, Buddhists and Jains.
