A rare philosophical treatise titled 'Yukti-Sudha' has been discovered in a family-held archive in rural West Bengal. Dating to the late 11th century, the manuscript offers a unique critique of the established Nyaya (logic) school, introducing a concept of 'contextual proof' that allows for variable interpretations of sensory data.
The text is written on treated palm leaves and is remarkably well-preserved. It highlights a previously undocumented school of logic that flourished in the eastern regions of the Indian subcontinent, focusing on the epistemology of doubt as a necessary precursor to spiritual realization. Scholars suggest this discovery could lead to a significant revision of the history of Indian dialectics.
