Gangesha Upadhyaya (c. 14th century) of Mithila founded Navya-Nyaya, the “New Logic”, with his monumental Tattvachintamani. His rigorous, almost mathematical analysis of inference and language set the method for nearly all later Indian logic and philosophy.
For centuries scholars came to Mithila — and especially to its great centre of learning — to study this discipline. Gangesha is, in a sense, the last and greatest flowering of the region’s ancient devotion to reason.
