Indian philosophical thought on Pramana (valid cognition) is a rich achievement that merits attention not only for its technical brilliance and variety but also for the ways in which it reverberates with contemporary discussions in science. In a spirit of free and open enquiry, Tibet House collaborated with the Drepung Monastic University at Mundgod, Karnataka to organize a monastic debate that was both traditional and contemporary. This debate was special in that it grew upon the pre-Buddhist traditions of thought on this critical question on logic while also incorporating a perspective that leapt across the centuries: that of contemporary physics. While the different schools such as Vedanta, Sankhya, Nyayavaisesika, Purvamimamsa, and Jaina were represented by scholars from academia, there was a lively interaction with monks being trained in traditional Tibetan philosophy at monasteries across India. The seminar was multilingual—with presentations and queries in Tibetan, Hindi, Sanskrit and English. While this book presents lightly edited versions of the key papers presented there, the lively debates in Tibetan could not be transcribed due to logistical difficulties. Hence, this bilingual volume attempts to make available to the scholarly community and curious students a valuable resource for understanding this crucial issue in logic from a rich, multifaceted, comparatist perspective. \n
