This paper analyzes the incisive counter-arguments against Gaṅgeśa’s defense of non-conceptual perception offered by the Dvaita Vedānta scholar Vyāsatīrtha in his Destructive Dance of Dialectic. The details of Vyāsatīrtha’s arguments have gone largely unnoticed by subsequent Navya Nyāya thinkers, as well as by contemporary scholars engaged in a debate over the role of non-conceptual perception in Nyāya epistemology. Vyāsatīrtha thoroughly undercuts the inductive evidence supporting Gaṅgeśa’s main inferential proof of non-conceptual perception, and shows that Gaṅgeśa has no basis for thinking (...) that non-conceptual perception has any necessary causal role in generating concept-laden perceptual awareness. He further raises a number of internal inconsistencies and undesirable consequences for Gaṅgeśa’s claim that non-conceptual states are introspectively invisible. His own causal theory of perception is more parsimonious than the Nyāya account, and is equally compatible with direct realism. I conclude by noting several striking parallels between Vyāsatīrtha’s views and the conceptualism of John McDowell, while also suggesting that Vyāsatīrtha's own conceptualism is not unduly constrained by some of McDowell’s limiting assumptions about concepts and perceptual contents.

Perceptual disjunctivism is a controversial thesis about perception. One familiar characterization of the thesis maintains that there is no common epistemic kind that is present in both veridical and non-veridical cases of perception. For example, the good case, in which one sees a yellow lemon, and the bad case, in which one hallucinates a yellow lemon, share a specific first-person phenomenology, being indistinguishable from the first-person point of view; however, seeing a yellow lemon and hallucinating a yellow lemon do not, (...) according to the disjunctivist, share a common epistemic kind. There are two types of disjunctivism: epistemological vs. metaphysical. John McDowell, 243–255, 2011, Philosophical Explorations, 16, 259–279, 2013) has articulated, refined, and defended one kind of disjunctivism. Tyler Burge, 1–78, 2005, Philosophical Explorations, 13, 43–80, 2011) has objected to many forms of disjunctivism, arguing that they are all inconsistent with the proximality principle in the vision sciences. PP requires an ability-general kind in common between relevantly similar perceptual states, such as seeing a yellow lemon and hallucinating a yellow lemon, which disjunctivism denies. Against the background of this debate some analytic epistemologists, such as Michael Martin, Alan Millar, 176–198, 2007), Berit Brogaard, 46–73, 2011), Duncan Pritchard, and Heather Logue, 105–133, 2013) remain attracted to some version of disjunctivism. Brogaard and Pritchard each have gone on to articulate and defend a version. Pritchard’s, for example, defends epistemological disjunctivism. Martin, Millar, and Logue, by contrast, have defended the idea that the disjunctivist is right about something, but perhaps not wholly correct about the nature of perception. In what follows, I articulate and defend the view that an interesting kind of disjunctivism is to be found through a reading of the Nyāya School of classical Indian philosophy. I articulate a version of perceptual disjunctivism informed by Nyāya perceptual theory that is not derivable from any single Nyāya philosopher. The view I offer is inspired by work on disjunctivism both in Anglo-analytic philosophy and in Nyāya scholarship, such as by Dasti and Phillips, 535–540, 2010), Ganeri, 541–550, 2010), Dasti, 1–15, 2012), Phillips, Vaidya, 562–585, 2013), and Schiller, 1–18, 2019). Importantly, the causal account I offer is distinct from Grice’s single-factor causal theory of perception by crucially involving a multi-factor causal theory of perception. My work on Nyāya perceptual theory derives primarily from Jaysankar Shaw’s account of Nyāya on the sources of knowledge, which is distinct from Stephen Phillips’ well-known account of Nyāya epistemology. Shaw’s theory has been developed and refined through textual analysis and dialectical engagement with the twentieth century Nyāya Pundit Philosopher, Viśvabandhu Tarkatīrtha. Like other modern Nyāya scholars, such as B. K. Matilal, A. Chakrabarti, 1–8, 2010), M. Chadha, J. Ganeri, and S. Phillips, 104–113, 2001, 2012), J. Shaw’s account shows how Nyāya epistemology is a living and continuing form of Indian philosophy. My goal here is twofold. On the one hand, I articulate multi-factor causal disjunctivism and show how it can be applied to the McDowell-Burge debate over the viability of disjunctivism and naïve realism. On the other hand, I aim to start a cross-cultural epistemological conversation with those that have contributed to the Anglo-analytic debate in anthologies, such as Haddock and Macpherson, Byrne and Logue, and introductions, such as Soteriou. The hope is that a cross-cultural epistemological investigation into disjunctivism will lead to better epistemic theorizing about the nature of perception. (shrink)

In this paper I aim to situate the Naiyayika theory of perception in contemporary philosophy of mind. Following the ancients, I suggest we reconsider the taxonomy and the assumed interactions between kinds of perceptual content. This reclassification will lead us to reconsider some aspects of the Cartesian conception of mind that continue to influence the work of contemporary theorists. I focus attention on different accounts of sensory perception favoured by ancient Indian Naiyayika philosophers and Descartes as a starting point for (...) reconsidering contemporary accounts of perceptual content.I show that Descartes' account of sensory perception provides the impetus for a causal-explanatory account of conceptual content in terms of its non-conceptual counterpart. Though contemporary philosophers claim to have cast off their Cartesian heritage, my discussion reveals that some of its tenets continue to influence the work of contemporary philosophers. I offer reasons for rejecting yet another Cartesian influence and recommend that we follow the Nyaya taxonomy of perceptual states. (shrink)
