11th-Century 'Yukti-Manjari-Vimarsha' Manuscript Discovered in Mewar Reshapes Medieval Theories of Logical Inference

Scholars at the Rajasthan Oriental Research Institute have announced the discovery of a rare 11th-century palm-leaf manuscript titled 'Yukti-Manjari-Vimarsha'. Found in a sealed stone chest in a village archive near Udaipur, the text is a profound critique of the Nyaya-Vaisheshika school of logic. It introduces a revolutionary concept of 'multi-layered inference,' arguing that truth cannot be reached through linear syllogisms alone but requires a web of contextual probabilities.

The manuscript is attributed to a little-known philosopher named Jayanta-Bhatta II, who appears to have integrated early mathematical concepts of sets into his logical framework. This discovery is particularly exciting for researchers of medieval Indian philosophy as it shows a level of epistemic skepticism and logical complexity that was previously thought to have developed much later during the Navya-Nyaya period. The text also includes marginalia that suggest it was used in public debates to challenge the prevailing orthodoxies of the time.
