Summary

अथ स्वतः परतः प्रमाणं परीक्ष्यते (An Examination of Intrinsic and Extrinsic Validity of Knowledge) by Ambikadatta Sharma explores a fundamental debate in Indian epistemology: whether the validity of knowledge (pramāṇya) is inherent in cognition itself (svatah) or depends on external factors (paratah). The author introduces the discussion by explaining that purposeful action requires certain knowledge, and that the usefulness of knowledge hinges on its reliability. Philosophers therefore distinguish between valid cognition (pramā) and invalid cognition (apramā), and they seek criteria to determine validity. Sharma traces the origins of this debate to early Mimamsa and Buddhist thinkers, showing how differing views led to divergent lists of recognized pramāṇas (means of knowledge). The article first outlines the theory of intrinsic validity, held by schools such as Advaita Vedanta, Prabhakara Mimamsa and some Buddhist logicians. According to this view, cognition carries its own mark of truth; one knows something and simultaneously knows that one knows it. Knowledge is self‑luminous, and error arises only when another cognition reveals the absence of the previously assumed object. Sharma explains how proponents of this view argue that doubt and subsequent verification presuppose some initial certainty. The author then presents the opposing theory of extrinsic validity, advocated by Naiyāyikas and Bhātta Mimamsakas, which maintains that cognition becomes valid only when corroborated by another pramāṇa. From their perspective, a bare cognition lacks normative force until it is confirmed by perception, inference or testimony; hence validity is a relational attribute. Sharma illustrates this position with examples of situations where initial impressions are corrected upon further evidence, arguing that this shows that truth is established through a process of mutual support among pramāṇas. The middle sections of the paper compare the arguments of key philosophers such as Dignāga, Dharmakīrti, Kumārila Bhaṭṭa and Jayanta Bhaṭṭa. Sharma shows how Dignāga’s logic emphasises self-awareness in cognition, while Kumārila insists on the necessity of external certification. He also discusses later attempts by Vedānta thinkers to reconcile the two positions by distinguishing between the intrinsic illumination of knowledge and its extrinsic applicability. Sharma highlights how this epistemological debate influenced broader discussions on the nature of error, the status of scripture, and the justification of moral and ritual action. The article concludes that the question of pramāṇya remains central to Indian philosophy because it determines both metaphysical and practical conclusions across schools.
