Dharmakirti (ca. 7th century), was an Indian scholar and one of the Buddhist founders of Indian philosophical logic. He was one of the primary theorists of Buddhist atomism, according to which the only items considered to exist are momentary Buddhist atoms and states of consciousness.
Dharmakirti presents most of his ideas in the guise of commentary on Dignaga's works, even if his theories go beyond what was presented by his predecessor. Some of his ideas, like his proof for the authority of the Buddha's words, are innovations, for Dignaga considered language just as fallible as inference.
There has long been disagreement among Indian and Tibetan doxographers as to how to categorize Dharmakirti's thought. The Gelug school asserts that he expressed Yogachara views, most non-Gelug Tibetan commentators assert that he expressed Sautrantika views and, according to one Tibetan source, a number of renowned later Indian Madhyamikas asserted that he expressed Madhyamaka views.
