In lieu of an abstract, here is a brief excerpt of the content:There's Nothing Wrong with Raw Perception:A Response to Chakrabarti's Attack on Nyāya's Nirvikalpaka PratyakṣaStephen H. PhillipsIn the lead article of the fiftieth anniversary issue of Philosophy East and West (January 2000), Arindam Chakrabarti elaborates seven reasons why Nyāya should jettison "indeterminate perception" and view all perception as determinate, that is to say, as having an entity (a) as qualified by a qualifier (F) as object (Fa). In his notes, (...) Chakrabarti invites a reply "so that," as he says, "I may know why immaculate perception is needed by Nyāya after all." The following is a response that shows not so much why indeterminate perception is needed by Nyāya but why it is identified as a causal factor necessary to the arising of some (not all) determinate perception defined as "perception of an entity as qualified." Here I follow Gaṅgeśa Upādhyāya, the fourteenth-century founder (with the help of a few less well known predecessors and contemporaries) of "New Logic," Navya Nyāya. Gaṅgeśa devotes an entire section (about one eighteenth) of the perception chapter of his monumental Tattvacintāmaṇi (Jewel of Reflection about Epistemology) to nirvikalpaka pratyaksṣa,1 and he is a chief target of Chakrabarti's chastisement.2Now, first of all, I want to follow Gaṅgeśa's ground rules. The Naiyāyika is not concerned with strategies about how to look good in debates (with Buddhists or anyone else). His attitude is truth-seeking, not eristic, and thus no reply will be given to Chakrabarti's agonizing about how best to show ourselves in controversies with (in particular, Buddhist) adversaries (and Wilfrid Sellars). Gaṅgeśa's reflections are vāda—and the section is rightly titled nirvikalpaka-vāda, vāda being "inquiries among friends"—directed to uncovering real causal factors, not to winning a debate or countering sophisms. Deception, or counter-deception, is sometimes appropriate—for instance, to protect a student or other judge from fallacies advanced by people of bad character. But not here. So I will lay out Gaṅgeśa's argument for identifying nirvikalpaka pratyaksṣa, and then run through Chakrabarti's list of reasons for rejecting it with an eye to the objection's salience to Gaṅgeśa's project. In other words, Chakrabarti's objections will be taken up with an eye to the truth as it appears to a Naiyāyika, not with an eye to how our team should best present itself to outsiders. I have little to say about Chakrabarti's complaints about appearances—in fact, I find them delightful. Don't let him fool you. There's no greater Naiyāyika enthusiast than Chakrabarti himself, and he knows how to distill a controversy to show the wisdom [End Page 104] of Nyāya in contrast to revealing a deficiency, as he appears to be doing here. He does this to make us think broadly about Nyāya in a contemporary context. And at the end I join him in making some very general comments about Nyāya's realism. First, Gaṅgeśa's argument and a rebuttal of Chakrabarti's seven reasons from Gaṅgeśa's point of view.There is no direct, apperceptive evidence for nirvikalpaka pratyaksṣa; rather, it is posited by force of the following inference as the first step of a two-step argument. "The perceptual cognition, 'A cow' (for example), is generated by a cognition of the qualifier, since it is a cognition of an entity as qualified (by that qualifier appearing), like an inference." The second step takes a person's first perception of an individual (Bessie, let us say) as a cow (i.e., as having some such property) as the perceptual cognition figuring as the inference's subject (or pakṣa) such that the cognizer's memory not informed by previous cow experience could not possibly provide the qualifier, cowhood. The qualifier has to be available, and the best candidate seems to be its perception in the raw, a qualifier (cowhood), that is to say, not (as some are wont to misinterpret the point... (shrink)

Besides seeing a rabbit or seeing that the rabbit is grayish, do we also sometimes see barely just the particular animal (not as an animal or as anything) or the feature rabbitness or grayness? Such bare, nonverbalizable perception is called "indeterminate perception" (nirvikalpaka pratyakṣa) in Nyāya. Standard Nyāya postulates such pre-predicative bare perception in order to honor the rule that awareness of a qualified entity must be caused by awareness of the qualifier. After connecting this issue with the Western debate (...) concerning the "myth of the given," seven distinct arguments are presented showing that the very notion of such indeterminate perception is epistemically otiose and that the Nyāya theory of perception is better off without it.

In lieu of an abstract, here is a brief excerpt of the content:Reply to Stephen PhillipsArindam ChakrabartiMuch as I am honored by Stephen Phillips' detailed defense, in the face of my methodological "refutation," of the Nyāya thesis that a raw perception of the qualifier is a necessary causal factor for some (not all) determinate perception of an entity as qualified, I am not fully convinced that my deeper qualms about the very idea of immaculate perception unimpregnated by predicative structure have (...) all been adequately addressed. Instead of a detailed response, which I intend to undertake elsewhere, I wish to underscore the central worry behind my fifth (which Phillips calls "good") and seventh (which Phillips calls "weak") objections.When I claimed that perception is introduced, taxonomically, as a variety of veridical awareness, I had in mind the opening line of Gaṅgeśa's section on the definition of perception:sā ca pramā caturvidhā, pratyakṣānumityupamitiśābdā-bhedātAnd such veridical awareness is of four kinds: perception, inferential knowledge, knowledge from similarity, and knowledge from words.1This seems to be flatly incompatible with the admission of a subclass of perceptions that are not veridical awarenesses!Why does Phillips say that I am simply mistaken? True, taxonomic difficulties cannot overturn empirical evidence. But recall that there is no direct apperceptive evidence for "raw perception." The sole evidence is a generalization from a whole series of mediate (parokṣa) awarenesses that can happily afford to be instrumentally and crucially caused by other awarenesses. On the other hand, immediacy, which is the hallmark of a perception, consists of not having another awareness in its causal nexus. My seeing of a wall as white is direct, rather than inferential, analogical, or testimonial, to the extent that I did not have to go through any other awareness first in order to arrive at this visual perception. An inductive generalization from other mediate (cognition-generated) cognitions should not have such inexorable probative power over our account of immediate sensory cognition as to force us into admitting a neither-true-nor-false third kind of raw awareness!Phillips seems to have overlooked the metaphor of "spelling" that I used in this context while giving my second objection. If the step-by-step picture of building up the content of perception that Gaṅgeśa assumes is correct, then each element of the perceptual content of the predicative perception that this is a flower—the universal flowerhood, the actual physical object identified as "this," and qualification as a cementing relation, in this case inherence—would first have to be cognized in the unconnected "raw" manner! Now, even if we somehow swallow the idea of seeing a universal barely and not in relation to any one of its instances, it simply makes no [End Page 114] sense to talk about a bare, raw, unstructured perceptual acquaintance with qualification or inherence! Logically and structurally one could argue that unless you have "got" a, b, and R first, you cannot have the complex aRb. But this is admittedly a process of logical postmortem dissection of a whole piece of direct qualificative perception. And the point of my metaphorical warning—"You need to have 'L' and 'O' and 'D' and 'N' to spell 'London,' but you do not need to spell 'L' or 'O' or 'D' or 'N' first. Single letters simply cannot be spelled!"—was this: there are all sorts of different ways of "getting." You need to "get" the qualifying feature somehow in order to see or hear or taste something as qualified by that feature, but you do not therefore need to see or hear or taste that feature alone first in a bare, raw, unqualified manner! I do believe, like a good Naiyāyika, that high-pitchedness (or fifthness, in the octave) can be heard although it is a sound-universal. But I refuse to admit that before I can hear a sung note as high-pitched or (the fifth) I must somehow hear that universal directly without hearing it in any note!The central point, once again, is this: all awareness is intentional, according to Nyāya. There are only three kinds of intentional roles that our awarenesses assign to their objects: the role of... (shrink)

This book is a defence of a form of realism which stands closest to that upheld by the Nyãya-Vaid'sesika school in classical India. The author presents the Nyãya view and critically examines it against that of its traditional opponent, the Buddhist version of phenomenalism and idealism. His reconstruction of Nyãya arguments meets not only traditional Buddhist objections but also those of modern sense-data representationalists.

Two major functions of the visual system are discussed and contrasted. One function of vision is the creation of an internal model or percept of the external world. Most research in object perception has concentrated on this aspect of vision. Vision also guides the control of object-directed action. In the latter case, vision directs our actions with respect to the world by transforming visual inputs into appropriate motor outputs. We argue that separate, but interactive, visual systems have evolved for the (...) perception of objects on the one hand and the control of actions directed at those objects on the other. This 'duplex' approach to high-level vision suggests that Marrian or 'reconstructive' approaches and Gibsonian or 'purposive-animate-behaviorist' approaches need not be seen as mutually exclusive, but rather as complementary in their emphases on different aspects of visual function.

This note aims to clarify which arguments do, and which arguments do not, tell against Conceptualism, the thesis that the representational content of experience is exclusively conceptual. Contrary to Sean Kelly’s position, conceptualism has no difficulty accommodating the phenomena of color constancy and of situation-dependence. Acknowledgment of nonconceptual content is also consistent with holding that experiences have nonrepresentational subjective features. The crucial arguments against conceptualism stem from animal perception, and from a distinction, elaborated in the final section of the paper, (...) between content which is objective and content which is also conceived of by its subject as objective.

It is commonly believed that the given consists of particulars cognized as such in perceptual experiences. Against this belief it is argued that perceptual cognition must be restricted to universal features. A Nyāya-Kantian argument is presented to reveal the incoherence in the very idea of a conception-free awareness of particulars. For the Naiyāyika philosophers and Kant, conceptualization is a necessary ingredient of perceptual experience, since perceptual cognition requires the possibility of recognition. From this it follows that perceptual cognition must be (...) restricted to universal features. This is surprising, for it rules out the possibility of knowledge of particulars. This counterintuitive consequence can be avoided by reconsidering our intuitive notion of knowledge of particulars. (shrink)
