Born in south India, Dharmakīrti was a leading representative of the Buddhist school of logic (pramāṇa) at Nālandā. Relying on Yogācāra and Sautrāntika doctrines, he wrote a number of key works, the most important of which is his Pramāṇa-vārttika, in which he extends and develops the thought of his predecessor Dignāga, dealing with matters of epistemology and logic. The Pramāṇa-vārttika contains four chapters dealing with inference, the validity of knowledge, sense-perception, and syllogisms. Few of Dharmakirti's writings survive in the original Sanskrit but all are preserved in Tibetan translation.
