Archaeologists and scholars at the Kameshwar Singh Darbhanga Sanskrit University have announced the discovery of a remarkably well-preserved palm-leaf manuscript titled Aptavachana-Siddhi-Kaumudi. Found within a forgotten wooden chest in a rural Mithila village, the text is a profound treatise on Aptavachana, or the testimony of a reliable person, a core concept in Indian epistemology. The manuscript dates back to the early 11th century and offers a sophisticated defense of verbal testimony as a primary source of knowledge, distinct from inference and perception.
Scholars suggest that this finding fills a significant gap in the history of the Nyaya-Vaisheshika schools of thought. Unlike contemporary texts that focused purely on formal logic, this manuscript delves into the ethical qualifications of a witness, arguing that the validity of truth is inextricably linked to the moral character and cognitive clarity of the speaker. This 'moral epistemology' provides a fresh perspective on how ancient Indian thinkers navigated the boundaries of subjective belief and objective truth.
