A previously unknown manuscript titled 'Yukti-Marga' (The Path of Reasoning) has been identified in a private family archive in Jaipur. Dating to the 11th century, this palm-leaf manuscript offers a unique critique of established Nyaya (logic) schools, introducing a novel system of "probabilistic inference" that allows for nuance in philosophical debate.
The treatise is attributed to a scholar named Vishnugupta II and focuses on the philosophy of evidence. It challenges the binary nature of truth-claims prevalent in medieval Indian logic, proposing instead a spectrum of certainty based on the quality of sensory data and the rigors of deductive syllogism, marking a major shift in our understanding of medieval epistemology.
