A significant 12th-century philosophical treatise, the Anumana-Kaustubha, has been discovered within the inner vaults of an ancient temple in Puri. The manuscript is a comprehensive commentary on inferential logic, offering a unique 'Odishan School' interpretation of the five-membered syllogism. Scholars are particularly excited by the text's nuanced defense of Anumana (inference) as a primary source of knowledge against contemporary skeptical critiques.
The author, identified as Madhusudana Dash, employs a sophisticated logical notation that predates later refinements in the Navya-Nyaya school. The discovery includes several chapters on semantic cognitive theory, exploring how the mind bridges the gap between a linguistic sign and its inferred reality. This manuscript is expected to become a cornerstone for future studies on the regional developments of logic in medieval India.
