Later Nyāya philosophers maintain that absences are real particulars, irreducible to any positives, that we perceive. The fourteenth-century Nyāya philosopher Gaṅgeśa argues for a condition on absence perception according to which we always perceive an absence as an absence of its counterpositive, or its corresponding absent object or property. Call this condition the ‘counterpositive condition’. Gaṅgeśa shows that the counterpositive condition is both supported by a plausible thesis about the epistemology of relational properties and motivates the defence of absence as (...) irreducible. But against Gaṅgeśa, the sixteenth-century Nyāya philosopher Raghunātha and his seventeenth-century commentators Bhavānanda, Jagadīśa, and Gadādhara identify cases in which the counterpositive condition fails. In this article, I examine the Nyāya-internal debate over this condition. I conclude that Raghunātha makes a compelling case that the counterpositive condition fails. (shrink)

Analytic philosophers have, since the pioneering work of B.K. Matilal, emphasized the contributions of Nyāya philosophers to what contemporary philosophy considers epistemology. More recently, scholarly work demonstrates the relevance of their ideas to argumentation theory, an interdisciplinary area of study drawing on epistemology as well as logic, rhetoric, and linguistics. This paper shows how early Nyāya theorizing about argumentation, from Vātsyāyana to Jayanta Bhaṭṭa, can fruitfully be juxtaposed with the pragma-dialectic approach to argumentation pioneered by Frans van Eemeren. I illustrate (...) the implications of this analysis with a case study from Jayanta Bhaṭṭa’s satirical play, Much Ado about Religion (Āgamaḍambara). (shrink)

In this paper, I propose to discuss the theory of error or Khyativāda with special reference to Nyāya philosophy. The error is an epistemological concept. As such it is contrasted with the truth. Philosophers, while dealing with the concept of error, have analyzed it from logical, metaphysical and psychological perspective. The problem of error in Indian philosophy is discussed in the different theories known as the Khyativāda. According to Nyāya School error is known as anyathākhyativāda. Here 'anyathā' literally means 'otherwise' (...) or 'else-wise'. When shell is perceived as silver, the erroneous cognition consists in the fact that the shell is perceived otherwise i.e. as other than what it really is. Error is an instance of erroneous judgement resulting from mischaracterization. Naiyāyikas bring in jñānalaksana pratyaksa to account for perceptual error. And the later Naiyāyikas are trying to explain the perceptual character of illusory experience, undoubtedly, an illusion, there is the attribution of false character to a perceived fact. (shrink)

This essay explores a problem for Nyāya epistemologists. It concerns the notion of pramā. Roughly speaking, a pramā is a conscious mental event of knowledge-acquisition, i.e., a conscious experience or thought in undergoing which an agent learns or comes to know something. Call any event of this sort a knowledge-event. The problem is this. On the one hand, many Naiyāyikas accept what I will call the Nyāya Definition of Knowledge, the view that a conscious experience or thought is a knowledge-event (...) just in case it is true and non-recollective. On the other hand, they are also committed to what I shall call Nyāya Infallibilism, the thesis that every knowledge-event is produced by causes that couldn’t have given rise to an error. These two commitments seem to conflict with each other in cases of epistemic luck, i.e., cases where an agent arrives a true judgement accidentally or as a matter of luck. While the Nyāya Definition of Knowledge seems to predict that these judgements are knowledge-events, Nyāya Infallibilism seems to entail that they aren’t. In this essay, I show that Gaṅgeśa Upādhyāya, the 14th century Naiyāyika, solves this problem by adopting what I call epistemic localism, the view that upstream causal factors play no epistemically significant role in the production of knowledge.

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.

The Nyāya school of classical Indian epistemology defended (by today’s standards) a radical version of epistemic externalism. They also gave arguments from their epistemological positions to an early version of disjunctivism about perceptual experience. In this paper I assess the value of such an argument, concluding that a modified version of the Nyāya argument may be defensible.

In the Nyāyasūtras (NS), the fundamental text of the Nyāya tradition, testimony is defined as a statement of a reliable speaker (āpta). According to the NS, such a speaker should possess three qualities: competence, honesty and desire to speak. The content of a discourse, including the prescriptions, is also considered reliable due to the status of a given author and the person that communicated it. -/- The Polish philosopher J.M. Bocheński similarly stresses the role of a speaker; he holds that (...) an authoritative source (whose discourse is called testimony) should be competent and truthful. The conditions of trust and superiority also apply. According to Bocheński, being an authority entails a special relation—it has a subject, object and field. Notably, Bocheński develops his own typology of testimony by distinguishing between what he calls epistemic and deontic authority. He asks questions such as: Who can be the subject of an authoritative statement? Which features should the speaker possess? How is authority recognised? Is there a universal or an absolute authority? What is the field of authority? Moreover, which qualities should the listener possess? -/- The Nyāya philosophers, both the ancient ones, like Akṣapāda Gautama, Vātsyāyana, Vācaspati Miśra, and the contemporary scholars of Nyāya, such as B. K. Matilal and J. Ganeri, were also concerned with these issues. -/- The aim of this paper is to discuss the above points in a comparative manner. I will argue that both Bocheński’s and the Nyāya accounts share very similar perspectives and encounter analogous problems. (shrink)

In this article an attempt is made to detect what could have been the dialectical reasons that impelled the Cār-vāka thinker Udbhatabhatta to revise and reformulate the classical materialistic concept of cognition. If indeed according to ancient Cārvākas cognition is an attribute entirely dependent on the physical body, for Udbhatabhatta cognition is an independent principle that, of course, needs the presence of a human body to manifest itself and for this very reason it is said to be a peculiarity of (...) the body. Therefore, Udbhatabhatta seems to de-scribe the cognizing faculty according to a double ontology: it is both a principle and a characteristic, both inde-pendent and dependent. Two philosophical contexts—Vaisesika and Nyāya schools—are here taken into account as possible anti-Cārvāka fault-finding points of view that spured Udbhatabhatta to reconsider the Cārvāka per-spective. Although we do not have so much textual material on this particular aspect of the ancient and medieval philosophical debate in India, it nonetheless can be supposed that Udbhatabhatta’s reformulation of the concept of cognition was a tentative response to the Vaisesika idea that cognition is not an attribute of the body, rather of the mind (which is here supposed to be eternal), and to the Naiyāyika perspective according to which cognition would be an attribute of an everlasting self. In the case of the Nyāya school, fortunately we have at our disposal the criticism put forward by Vātsyāyana against the materialistic conception of cognition during this time. By examining some Vātsyāyana’s objections, it will emerge that Udbhatabhatta’s idea of cognition really seems to have the aspect of a consistent answer to them, from a renewed materialistic point of view.

This paper elaborates upon various responses to the Problem of the One over the Many, in the service of two central goals. The first is to situate Huayan's mereology within the context of Buddhism's historical development, showing its continuity with a broader tradition of philosophizing about part-whole relations. The second goal is to highlight the way in which Huayan's mereology combines the virtues of the Nyāya-Vaisheshika and Indian Buddhist solutions to the Problem of the One over the Many while avoiding (...) their vices.

Pakṣilasvāmin's introduction to his Nyāyabhāṣyam is perhaps one of the most interesting texts of the older Nyāya indispensable to the understanding of the system. This is not because the ideas expressed therein were not to be surpassed at a later period, but because in it the development of the school appears fixed, as it were, in a "transitory moment" (transitorisches Moment), and we see there for the first time that line of thought, which historically took form in the Nyāya philosophy, (...) becoming aware of itself in a clear, though archaic, manner. Furthermore, if we bear in mind to what extent such an interpretation of a school (given by itself) determines its development, the importance of Pakṣilasvāmin's text for the history of Nyāya cannot be over-estimated.
