A rare palm-leaf manuscript has been recovered from a family archive in a remote village near Darbhanga. Known as the 'Tarka-Viveka', the text offers a previously unknown critique of late-stage Nyaya logic, specifically addressing the metaphysics of counter-factual conditional reasoning. Scholars note that the author, a female logician named Shivananda-Devi, argues that logical truth is not merely a reflection of external reality but a construction of epistemic intent.
The manuscript's discovery provides a vital missing link in the evolution of the Navya-Nyaya school, suggesting a much earlier transition toward the abstract formalization of logic than previously believed. The archive also contains smaller fragments discussing the 'logic of doubt' as a valid path toward ultimate truth, bridging the gap between rigorous dialectics and spiritual inquiry.
