An Indian Theory of Defeasible Reasoning

The pre-Gaṅgeśa Navya-Nyāya treatise Upādhidarpaṇa (UD) deals with the upādhi, a key concept in the Navya-Nyāya theory of inference. This volume is the first published edition and translation of the only manuscript of the UD. Notes have been added to elucidate the historical context of the authors, works, and philosophical doctrines in the UD.
