Dharmakiirti (seventh century A.D.), Indian Yogacara Buddhist philosopher and logician. His works include Pramanavarttika (‘Explanation of the Touchstones’), a major work in logic and epistemology; and Nyayabindu, an introduction to his views. In Santanantara-siddhi (‘Establishment of the Existence of Other Minds’) he defends his perceptual idealism against the charge of solipsism, claiming that he may as legitimately use the argument from analogy for the existence of others (drawing inferences from apparently intelligent behaviors to intelligences that cause them) as his perceptual realist opponents. He criticized Nyaya theistic arguments. He exercised a strong influence on later Indian work in logic. K.E.Y.
