Logic theory proposed by Nyaya is quite systematic and had an important influence on the history of Indian philosophy and attracted many ancient Indian philosophers to pay attention to the problem of logic. Some were prominent Buddhist thinkers. In the course of the evolution of Buddhist Hetuvidya, Theravada and early Mahayana had less discussion on logic, while Yogacara (a school of Mahayana) paid more attention to this respect. Buddhist *Hetuvidya* texts were mostly composed by Yogacara thinkers, and of them, Dignaga (about 5ᵗʰ to 6ᵗʰ centuries CE) had prominent achievements in respect of Hetuvidya, and is often used to divide the history of Hetuvidya development and before him is “old Hetuvidya” and after him is “new Hetuvidya” and Dignaga is a leading character for new Hetuvidya.
