the works of Dinnāga and Dharmakīrti, but some of them also wrote original works and developed the tradition in new directions. The work of this tradition also went on to influence the Buddhist Madhyamaka school, through the work of figures like Bhāvaviveka (c. 500 - c. 578), Jñanagarbha (700-760), and Śāntarakṣita (725–788). These thinkers attempted to adopt the logical and epistemological insights of Dinnāga and Dharmakīrti to defend the tenets of the Madhyamaka school. Dignāga's tradition of logic and epistemology continued in Tibet, where it was expanded by thinkers such as Cha-ba (1182–1251) and Sakya Pandita (1182–1251). Dignāga also influenced non-Buddhist Sanskrit thinkers. According to Lawrence J. McCrea, and Parimal G. Patil, Dignāga set in motion an "epistemic turn" in Indian philosophy. After Dignāga, most Indian philosophers were now expected to defend their views by using a fully developed epistemological theory (which they also had to defend).
