Philosophy East and West

More or less happy with the reviews, I would like mainly, in response, to identify advances made in the study of Gaṅgeśa. Anand Vaidya articulates a clearer overview of Gaṅgeśa's theory of knowledge; Eberhard Guhe shows a better way to render the notion of vyāpti, "pervasion," which is central in the theory of inference as a knowledge source; and Michael Williams, too, shows need for improvement on that score as well as for elaboration of matters taken up by classical commentators that are given short shrift in my running comments. For example, whereas long discussions are provoked by Gaṅgeśa's definition of "knowledge," pramā, major points in the purvapakṣa in the section on proving the existence of an īśvara, a "Lord," seem, as Williams says, "threadbare."

Vaidya, following Burge (2003), introduces a distinction between entitlement and justification: entitlement is the kind of unreflective epistemic warrant delivered by Gaṅgeśa's pramāṇa, "knowledge sources," working automatically in our everyday lives, whereas justification requires self-conscious certification, prāmāṇya-jñapti. Thereby splitting the horns of a dilemma posed by internalist accounts of knowledge in opposition to externalist ones, Burge and Vaidya are able to incorporate the most [End Page 519] attractive features of each approach. The entitlement/justification distinction cashes out, I may add, to Vaidya's elucidation, Nyāya's deeply held doctrine of parataḥ-prāmāṇya, "certification by another," against the view of "intrinsic certification," svataḥ-prāmāṇya, of Prabhākara and others. As Williams notes, Prābhākara positions, for which Gaṅgeśa sometimes shows sympathy, may have led him to presume that an anubhava—"awareness" or "presentational experience" in my translation, "fresh news" in Matilal's snappy rendering—is an episode of knowledge, pramā, "unless one knows otherwise," bādhakam vinā.

On reflection, one sees that such a presentation (it could be perceptual, inferential, analogical, or testimonial) has been produced by a pramāṇa, or, in abnormal cases, not, and so by a "pramāṇa-pretender," a pramāṇaābhāsa, as in seeing a mirage. Again, an anubhava is not just any old cognition or "thought" (pace Das 2021, p. 162); it is defined as nonrecollective. Unlike a deliverance of a genuine pramāṇa, some instances may, on examination, prove to be a-pramā, "non-knowledge," but are, nevertheless, at the animal level, sufficient to provoke and guide action that would not be unhesitating were there doubt in any way. A thirsty Maya, in Vaidya's example, would naturally move in the direction of the water she "sees." But she would hesitate were she to learn from her friend about the unreliability of water-perception in the current circumstances. At the reflective level, where she is unsure whether the anubhava she apperceives is pramā or apramā, her action, including speech (implying assertability), is altered.

So far so good in Vaidya's reconstruction. But Gaṅgeśa does not himself pronounce on the question of whether, after learning about the defeater, Maya would still be entitled to her perceptual belief that there is water in the distance. In the volumes under review, I assumed that she would not be "justified" and indeed that she would no longer have the belief (if we may speak about "beliefs"). The defeater grasped at the reflective level would mean not only that she could not certify the perceptual deliverance but also that there would be no knowledge. Clearly, she can't certify it, and thus, as Vaidya reasons, loses the right to assert. But maybe he's correct that, according to Gaṅgeśa's sensibilities, she does not lose the perceptual knowledge. She would remain entitled to her belief.

Personally, I think this is wrong, but Vaidya's understanding does have the merit of explaining why some later Naiyāyikas apparently took absurd positions on epistemic luck (Bhattacharya 1996, p. ix). I think that Maya would lose her entitlement, too, but what if, after being informed of the unreliability of water-perception...
