A previously unknown 8th-century Sanskrit manuscript, the 'Pramana-Samgraha', has been recovered from a private ancestral library in a remote village in Mithila. The text serves as a comprehensive compendium of the Nyaya-Vaisheshika school of logic, offering new arguments regarding the validity of verbal testimony as a source of knowledge. It is attributed to a scholar named Vatsyayana-Misra, whose works were previously thought to be entirely lost.
The discovery is expected to reshape the history of medieval Indian epistemology. The manuscript includes a unique section on the 'Philosophy of Doubt', where the author argues that skepticism is not an end state but a necessary precursor to authentic realization. Historians note that the preservation of this palm-leaf text is extraordinary given the region's humid climate.
