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)

The strainer tests the strength of a definition of a particular kind. Suppose the definition D is stated in terms of an absence, and x is a definiendum of D. The strainer collects each x-token or x-individual that dissatisfies D in a specific case. Then, all the x-individuals put together would be equivalent to the type x. Hence—one would be forced to conclude that—in a sense, x dissatisfies D. This is a case of under-application of D, since, despite being a (...) definiendum of D, x dissatisfies D. Therefore, D would be too narrow. Similarly, the strainer may detect over-application too. By using the strainer, Raghunātha Śiromaṇi demonstrated that Gaṅgeśa’s conclusive definition of pervasion had a defect, and redefined pervasion. The strainer test is based on intuitive principles. It may disqualify a definition that has an absence in its definiens. Therefore, strainer-proofing becomes an important consideration that must be borne in mind every time we formulate such a definition. (shrink)

This paper intends to present a cognitive model of anuvyavasāya through causal and logical analysis of the moment examinations (kṣaṇavicāra), remaining consistent with the fundamental presuppositions of the Nyāya system. The Naiyāyikas hold that no cognition is self-revealing in nature. A subsequent mental perception, introspection or after-perception (anuvyavasāya) reveals the determinate cognition. In anuvyavasāya, along with the cognition and Self, the object of determinate cognition (vyavasāya) also is known. The vyavasāya itself, working as cognition-induced extraordinary sensory connection (jñānalakṣaṇa alaukika sannikarṣa), (...) connects its object to the mental sense-organ. We can formulate the moment examination of the after-perception ‘I know that it is a pitcher’ in the following way: (M1) sense-pitcher connection, (M2) indeterminate perception of pitcher, (M3) determinate perception of pitcher, (M4) indeterminate perception of the vyavasāya, (M5) determinate mental perception of vyavasāya, i.e. anuvyavasāya. But, according to the Naiyāyikas cognition exists only for two moments. So at M5, the vyavasāya is destroyed, which is the object or cause of anuvyavasāya. Gaṅgeśopādhyāya replies that a cause is only required to exist at the immediately previous moment of the effect. The paper analyses the moment examinations of anuvyavasāya offered by Udayanācārya and Vardhamānopādhyāya and tries to arrive at a consistent model of anuvyavasāya. The paper also discusses whether at all anuvyavasāya is an instance of jñānalakṣaṇa. Udayana’s account suggests that it is so, but Gadādhara does not admit it. On the other hand, Harirāma Tarkavāgīśa and Raghunātha Śiromaṇi hold that like vyavasāya all the internal states having contents (saviṣayaka) may work as jñānalakṣaṇa sannikarṣa. (shrink)

Engagement with texts however distant from us in culture and history—distant, that is, from contemporary anglophone philosophy—tries to make them part of an ongoing conversation, focusing on topics and arguments as opposed to context or history. And, as Jonardon Ganeri reports of the innovative Nyāya philosopher Raghunātha Śiromaṇi, who emerges as the hero of The Lost Age of Reason: Philosophy in Early Modern India 1450–1700, this can take the form of “asides and marginal notes, of the sort one makes not (...) when one is trying to interpret the text so much as when one is thinking with it and beyond it”. The purpose is to have your own insights. Such an approach when packaged nowadays makes us... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Semantic Powers: Meaning and the Means of Knowing in Classical Indian PhilosophyHarold CowardSemantic Powers: Meaning and the Means of Knowing in Classical Indian Philosophy. By Jonardon Ganeri. Oxford: Oxford University Press, 1999. Pp. x + 266.In Semantic Powers: Meaning and the Means of Knowing in Classical Indian Philosophy, Jonardon Ganeri adds to our understanding of the Nyāya philosophy of language in the modern English-speaking world. Building on Bimal (...) Matilal's introduction to Nyāya thought in Matilal's foundational Epistemology Logic and Grammar in Indian Philosophical Analysis (1971) and on Karl Potter and Sibajiban Bhattacharyya's Nyāya-Vaiśeṣika from Gangeśa to Raghunatha Siromani (1993), Ganeri's clearly written book valuably extends our knowledge of the Nyāya philosophy of language by its exposition of the seventeenth-century Nyāya philosopher Gadādhara's Saktivāda or "Essay on Semantic Power." Ganeri's exposition is based on having read the first half of the Saktivāda text with Matilal, before the latter's untimely death, and the second half with Bhattacharyya in Calcutta.In the Saktivāda, Gadādhara defends key Nyāya claims as to how language conveys meaning. In the first half of the text, the author deals with such questions as whether languages are convention-based, whether the central function of language is as an instrument of knowing, whether word meaning or sentence meaning is conceptually prior, and whether the notion of meaning is reducible to physical and/or psychological concepts. In the second half, Gadādhara looks at the semantic problems connected with particular constructions: notably proper and theoretical names, anaphors, indexicals, and the quantifiers. The English exposition of Gadādhara's text offered by Ganeri in this book covers the same topics.According to Gadādhara and the Nyāya philosophy, "the language faculty is a sui generis epistemic faculty, reducible to neither perception nor inference nor some combination of these two. The question for the Naiyāyika is: what properties must the language faculty have if it is in this way to be a source of knowledge?" (p. 15). The Nyāya approach also places an emphasis on testimony as a valid source of knowledge (pramāna), which it understands simply as the transmission by language of knowledge from the speaker to the hearer. The "Communication-intention" variable, discussed by recent thinkers such as McDowell, is not dealt with by Nyāya thinkers, who would deny that the acquisition of knowledge by testimony involves anything like the recognition of the speaker's intentions. Rather, the Nyāya thesis is "that understanding typically consists in direct, non-inferential assent, is in sharp contrast to the assumption implicit in McDowell's position: that assenting to another's utterance is never direct, but always depends on the speaker's intentions, or of the speech-act performed by the speaker" (p. 17). In supporting the Nyāya position, Ganeri appeals to Frege's theory of understanding.The basic idea in the Nyāya philosophy of language is that each of us is endowed with a language faculty, analogous to our perceptual faculty, which generates beliefs from perceived utterances. It has a meaning function. As Ganeri puts it: [End Page 419]My testimonial faculty fixes, as it were, a mapping from utterances of a given language to belief contents. The 'meaning' of a statement for me is, by definition, the belief content to which it is mapped by my testimony faculty. If I am able to understand every statement I hear, the language processing mechanism which underpins this faculty must have a certain compositional structure, and that leads to an assignment of belief-content components to subsequential elements in the language, (p. 29)This thought of Gadādhara, dating from about 1700 C.E., resonates with Chomsky's contemporary ideas of "deep structure" and, in classical Indian philosophy, with Bhartṛhari's fifth-century notion of innate-structuring ideas within consciousness (see Coward and Raja, Encyclopedia of Indian Philosophies, vol. 5). Like Bhartṛhari, Gadādhara takes the sentence to be the irreducible meaning-bearing unit of language.While Karl Potter and Sibajiban Bhattacharyya's volume 6 of The Encyclopedia... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:A Time of Novelty: Logic, Emotion, and Intellectual Life in Early Modern India, 1500-1700 C.E. by Samuel WrightAnusha Rao (bio)A Time of Novelty: Logic, Emotion, and Intellectual Life in Early Modern India, 1500-1700 C.E. By Samuel Wright. Oxford: Oxford University Press, 2021. Pp. xxi + 278. Paper $99.00, isbn 978-0-197568-16-3Samuel Wright's A Time of Novelty examines the discipline of Nyāya, or Sanskrit logic, between 1500 and 1700 CE (...) and argues that novelty, both as an intellectual and affective category, was the structuring principle through which Nyāya intellectuals built a philosophical community in early modernity. Wright uses a set of essays and commentaries by Nyāya philosophers on a range of topics to reflect on how intellectual life in this period was shaped by critical inquiry, emotion, and manuscript culture.The book studies a very fruitful, if contentious, period within the history of Sanskrit intellectual disciplines. Sheldon Pollock's "Sanskrit Knowledge Systems on the Eve of Colonialism" (SKSEC project) was the first to draw attention to this period as early modernity in India. Pollock has pointed to both parallels with and differences from modernity in Europe. Since then, scholarly attention has been directed to how periodizing techniques were used by Nyāya intellectuals, and to the relationship that these "new" Nyāya intellectuals had with the tradition. While Wright is in general agreement with the aims of the SKSEC project, he argues against focusing exclusively on intellectual historical change without understanding the values and sentiments that underwrite intellection. For this reason, the book undertakes the challenging task of linking a set of understudied Nyāya arguments with philosophy of emotions to understand affective novelty. This offers interesting insights into the emotional concerns behind Nyāya intellection in a way that earlier scholarship has been unable to, but it has the disadvantage of imposing frameworks alien to Nyāya philosophers onto their arguments--such as Wright's arguments about how space is produced in chapter 3.The book is organized into six chapters, each of which deals with an important topic within Nyāya arguments in early modern India. While the first four chapters, titled "Doubt," "Objectivity," "Happiness," and "Dying," directly deal with these contentious issues and debates around them by Nyāya thinkers, in the last two chapters, "Space" and "Time," Wright does not take up specific arguments from primary texts, but focuses on how we can best understand the space that Nyāya intellectuals inhabited and how novelty can be conceptualised in time. [End Page 1]In the first chapter on doubt, Wright zooms in on arguments about how doubting cognitions emerge, focusing particularly on Raghunātha Śiromaṇi and how commentators present his novel position on the issue. Earlier Nyāya intellectuals argued that speech and other indirect forms of perception could not generate doubting cognitions. Instead, they advanced a theory of apperceptive doubt, where doubt arises in a subsequent, remembering cognition. Raghunātha, on the other hand, argues that doubting cognitions can arise directly from speech, and he substantially changes the definition of doubt, a change which is noted and carefully explained by his commentators. Beginning with the theory of doubt allows Wright to then examine how the new definition of doubt leads to structural changes in the crafting of Nyāya debates, particularly in genres such as the short essay (vāda), where the topic of contention is stated in the newly developed format. Wright also links this debate with the notion of trust. Careful attention to how the debate is framed by commentators also underscores the emotional underpinnings of the argument--the "old" view is not to be trusted, since it does not stand up to reasoning (p. 60). Doubting cognitions are not ignored in Nyāya, but become the beginning point of debates and discussions, demonstrating that Nyāya philosophers in early modern India were fashioning a community that engaged peers through new ways of understanding and caring about critical inquiry.The second chapter focuses on arguments around objectivity and deals at greater length with the periodizing techniques used by Nyāya thinkers in the early modern period.

This study, under the title of an explanation of the New Nyäya views on negation, deals with the Navya-nyäya as a whole. The peculiarity of their theory of negation is that one can see the absence of an object in a given place. It includes the Sanskrit texts and translations of the Abhäva-väda of Gangesa and the Nañ-väda of Raghunätha. Though written for both Sanskritists and philosophers, the frequent use of Sanskrit terms almost requires that the reader be a Sanskritist--though (...) by keeping in mind the translations, previously given, it could be valuable. This is not an exposition of logic for beginners, but an exposition for scholars of a particular system. Renditions into modern logic are given throughout. Chapter headings include: On Cognition; The Content of Cognition and the Meaning Problem; On Relation; The Counterpositive of an Absence; The Ontological Status of Content-ness; The Relational Adjuncts; The Limitors and Quantificational Logic; Circularity; On Negation.--P.
