This paper proposes a critical analysis of that interpretation of the Nāgārjunian doctrine of the two truths as summarized—by both Mark Siderits and Jay L. Garfield—in the formula: “the ultimate truth is that there is no ultimate truth”. This ‘semantic reading’ of Nāgārjuna’s theory, despite its importance as a criticism of the ‘metaphysical interpretations’, would in itself be defective and improbable. Indeed, firstly, semantic interpretation presents a formal defect: it fails to clearly and explicitly express that which it contains logically; (...) the previously mentioned formula must necessarily be completed by: “the conventional truth is that nothing is conventional truth”. Secondly, after having recognized what Siderits’ and Garfield’s analyses contain implicitly, other logical and philological defects in their position emerge: the existence of the ‘conventional’ would appear—despite the efforts of semantic interpreters to demonstrate quite the contrary—definitively inconceivable without the presupposition of something ‘real’; moreover, the number of verses in Nāgārjuna that are in opposition to the semantic interpretation (even if we grant semantic interpreters that these verses do not justify a metaphysical reconstruction of Nagarjuna’s doctrine) would seem too great and significant to be ignored.

Although somewhat neglected in the scholarly debate, Vṛṣabhadeva’s commentary (known as Sphuṭākṣarā or Paddhati, possibly 8th c. CE) on Vākyapadīya’s first chapter, offers a remarkable analysis of Bhartṛhari’s views on metaphysics and philosophy of language. Vākyapadīya’s first four kārikās deal with ontological issues, defining the key elements of Bhartṛhari’s non-dualistic edifice such as the properties of the unitary principle, its powers, the role of time and the ontological status of worldly objects. Vṛṣabhadeva’s interpretation of the kārikās in question is intriguing (...) and seems to be guided by the urgency to find a solution to the riddle which every non-dualistic theory has to face: how is it possible to postulate a unitary principle of reality when reality is cognized as multiple? In accomplishing the task Vṛṣabhadeva proposes various solutions (some of them based on concepts which are hardly detectable in Vākyapadīya and appear close to the ones propounded in certain trends of Advaita Vedānta), finally suggesting an explanation which, focusing on the pragmatic aspect of language, is altogether consistent with Bhartṛhari’s theoretical picture.

Professional philosophers say it’s obvious that a Gettier subject does not know. But experimental philosophers and psychologists have argued that laypeople and non-Westerners view Gettier subjects very differently, based on experiments where laypeople tend to ascribe knowledge to Gettier subjects. I argue that when effectively probed, laypeople and non-Westerners unambiguously agree that Gettier subjects do not know.

Is knowledge justified true belief? Most philosophers believe that the answer is clearly ‘no’, as demonstrated by Gettier cases. But Gettier cases don’t obviously refute the traditional view that knowledge is justified true belief (JTB). There are ways of resisting Gettier cases, at least one of which is partly successful. Nevertheless, when properly understood, Gettier cases point to a flaw in JTB, though it takes some work to appreciate just what it is. The nature of the flaw helps us better (...) understand the nature of knowledge and epistemic justification. I propose a crucial improvement to the traditional view, relying on an intuitive and independently plausible metaphysical distinction pertaining to the manifestation of intellectual powers, which supplements the traditional components of justification, truth and belief.

This paper provides a principled and elegant solution to the Gettier problem. The key move is to draw a general metaphysical distinction and conscript it for epistemological purposes. Section 1 introduces the Gettier problem. Sections 2–5 discuss instructively wrong or incomplete previous proposals. Section 6 presents my solution and explains its virtues. Section 7 answers the most common objection.

The concept of “self-awareness” ( svasaṃvedana ) enters Buddhist epistemological discourse in the Pramāṇasamuccaya and - vṛtti by Dignāga (ca. 480–540), the founder of the Buddhist logico-epistemological tradition. Though some of the key passages have already been dealt with in various publications, no attempt has been made to comprehensively examine all of them as a whole. A close reading is here proposed to make up for this deficit. In connection with a particularly difficult passage (PS(V) 1.8cd-10) that presents the means (...) of valid cognition and its result ( pramāṇa/pramāṇaphala ), a new interpretation is suggested, inspired by the commentary of Jinendrabuddhi. This interpretation highlights an aspect of selfawareness that has hitherto not been claimed for Dignāga: self-awareness offers essentially subjective access to one’s own mental states and factors.

The article considers what happened to the Buddhist concept of self-awareness ( svasaṃvedana ) when it was appropriated by Śaiva Siddhānta. The first section observes how it was turned against Buddhism by being used to attack the momentariness of consciousenss and to establish its permanence. The second section examines how self-awareness differs from I-cognition ( ahampratyaya ). The third section examines the difference between the kind of self-awareness elaborated by Rāmakaṇṭha (‘reflexive awareness’) and a kind elaborated by Dharmakīrti (‘intentional self-awareness’). (...) It is then pointed out that Dharmakīrti avails himself not only of intentional self-awareness but also of reflexive awareness. Some remarks on the relationship between these two strands of Dharmakīrtian Buddhism are offered. The conclusion points out that although self-awareness occurs in Buddhism as inextricably linked with anātmavāda , the doctrine of no-self, and sākāravāda , the view that the forms we perceive belong not to external objects but to consciousness, it is used by Rāmakaṇṭha to refute both of these views. An appendix addresses the problem of how precisely to interpret Dharmakīrti’s contention that conceptual cognition is non-conceptual in its reflexive awareness of itself. (shrink)

A pivotal focus of exegesis of Nāgārjuna's Mūlamadhyamakakārïkā (MMK) for the past half century has been the attempt to decipher the text's philosophy of language, and determine how this best aids us in characterizing Madhyamaka thought as a whole. In this vein, MMK 24:18 has been judged of particular weight insofar as it purportedly insists that the concepts pratītyasamutpāda (conditioned co-arising) and śūnyatā (emptiness), both indispensable to Buddhist praxis, are themselves only "nominal" or "conventional," that is, they are merely labels (...) that do not referentially signify anything that can be taken to be an ontologically ultimate reality. In various guises, as a result of this explication, Nāgārjuna's thought has been seen to embrace an overarching linguistic nominalism or conventionalism in which words, whether they are used for the purposes of theory or practice, though they serve as commonly accepted currency in the transactions of worldly business (vyavahāra), are in the end only ideas (prajñapti) or metaphysical fabrications (prapanca). This interpretation is largely due to tenaciously inaccurate translations and expositions of MMK 24:18 and their dependence on Candrakīrti's peculiar analysis of this verse in his Prasannapadā. This essay will attempt to correct both the diction of the major translations of MMK 24:18 and the fictions of nominalism and conventionalism that the consequent interpretations of this stanza have perpetuated. The argument that will be developed in the course of this essay is that Candrakīrti's reading of this verse proffers a strong form of linguistic nominalism that Nāgārjuna himself does not embrace. It will be shown, based on everything else found in the MMK, that Nāgārjuna, rather than advocating the mere nominal or conventional status of terms such as pratītyasamutpāda and sunyata, demands they be accepted as both pedagogically useful and even referentially accurate descriptions of the world as it is.

Perhaps no other classical philosophical tradition, East or West, offers a more complex and counter-intuitive account of mind and mental phenomena than Buddhism. While Buddhists share with other Indian philosophers the view that the domain of the mental encompasses a set of interrelated faculties and processes, they do not associate mental phenomena with the activity of a substantial, independent, and enduring self or agent. Rather, Buddhist theories of mind center on the doctrine of no-self (Pāli anatta, Skt.[1] anātma), which postulates (...) that human beings are reducible to the physical and psychological constituents and processes which comprise them.

The late 16th century Indian philosopher Vijñānabhikṣu is most well known today for his commentaries on Sāṃkhya and Yoga texts. However, the majority of his extant corpus belongs to the tradition of Bhedābheda (Difference and Non-Difference) Vedānta. This article elucidates three Vedāntic arguments from Vijñānabhikṣu’s voluminous commentary on the Brahma Sūtra, entitled Vijñānāmṛtabhāṣya (Commentary on the Nectar of Knowledge). The first section of the article explores the meaning of bhedābheda, showing that in Vijñānabhikṣu’s understanding, “difference and non-difference” does not entail (...) a denial of the principle of contradiction. The second shows how the relation between the individual soul (jīva) and Brahman can be understood as a relation of part and whole. The third section discusses Brahman as cause of the world, and Vijñānabhikṣu’s particular formulation of Brahman as “locus cause” (adhiṣṭhānakāraṇa). Understanding these arguments enables us to appreciate how Vijñānabhikṣu’s Difference and Non-Difference Vedānta is a credible alternative to the Advaita Vedānta schools prevalent in northern India in the late medieval period, and how in his later works Vijñānabhikṣu built upon this Difference and Non-Difference metaphysical framework to argue for the unity of Vedānta, Yoga, and Sāṃ-khya philosophies.

Pleasure, in the inclusive usages most important in moral psychology, ethical theory, and the studies of mind, includes all joy and gladness — all our feeling good, or happy. It is often contrasted with similarly inclusive pain, or suffering, which is similarly thought of as including all our feeling bad. Contemporary psychology similarly distinguishes between positive affect and negative affect.[1..

In this paper I propose to inquire into the theory of self-awareness propounded by the two Buddhist epistemologists, Dignaga and Dharmakirti. I first give an outline of the Buddhist notion of consciousness, then deal with the notion of objectual appearance, and finally dwell on the theory itself together with certain arguments in its favor. It is shown that the Buddhists subscribed themselves to the following self-awareness thesis: that our waking consciousness is always pre-reflectively and nonconceptually aware of itself. Adopting an (...) approach of interpretive and comparative analysis, I also clarify significant differences between the theory and the correspondent Cartesian views in order to reveal the theory's contemporary relevancy.

Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of (...) acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The out- side world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the gov- erning laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Sev- eral lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual “filling in,” visual stability despite eye movements, change blindness, sensory substitution, and color perception.

This work investigates intuitions' nature, demonstrating how philosophers can best use them in epistemology. First, the author considers several paradigmatic thought experiments in epistemology that depict the appeal to intuition. He then argues that the nature of thought experiment-generated intuitions is not best explained by an a priori Platonism. Second, the book instead develops and argues for a thin conception of epistemic intuitions. The account maintains that intuition is neither a priori nor a posteriori but multi-dimensional. It is an intentional (...) but non-propositional mental state that is also non-conceptual and non-phenomenal in nature. Moreover, this state is individuated by its progenitor, namely, the relevant thought experiment. Third, the author provides an argument for the evidential status of intuitions based on the correct account of the nature of epistemic intuition. The suggestion is the fitting-ness approach: intuition alone has no epistemic status. Rather, intuition has evidentiary value as long as it fits well with other pieces into a whole, namely, the pertinent thought experiment. Finally, the book addresses the key challenges raised by supporters of anti-centrality, according to which philosophers do not regard intuition as central evidence in philosophy. To that end, the author responds to them, showing that they fail to affect the account of intuition developed in this book. This text appeals to students and researchers working in epistemology.

This essay develops an intercultural approach to the skeptical way of life through an interpretation of two classical traditions: the Pyrrhonian tradition of ancient Greece and the Madhyamaka Buddhist tradition of classical India. The skeptical way of life is characterized by several important features, including a goal of tranquility or of freedom from disturbance and suffering, a philosophical strategy of dialectical argument that terminates in the suspension of judgment or the abandonment of views, a purgative philosophic therapy, and life without (...) belief. A constellation of practical questions that emerge from the skeptical way of life are also considered, including the skeptic’s character, conformity, and care. One of the principal aims of the essay will be to develop this intercultural account of the skeptical way of life and to show by way of this illustrative example how our understanding of skepticism and ancient philosophy is enhanced through an intercultural approach.

As Buddhist externalists, both Saṅghabhadra and Śubhagupta claim the existence of an external object on the basis of atomism. In this paper, I will show the interrelationship between Saṅghabhadra’s and Śubhagupta’s atomic theories. Regarding the ontological status of the aggregation of atoms, both of them agree on a Vaibhāṣika principle that the aggregation of atoms, as a real substance, can serve as an object-support of cognition. Based on this principle, their similarities can be further explicated from three aspects. Regarding epistemology, (...) Śubhagupta differs from Saṅghabhadra on the cognitive process of the awareness of something blue. For Saṅghabhadra, a gross object is grasped by non-conceptual sensory consciousness because it is a real entity aggregated by atoms. Through the function of vitarka of sensory consciousness, an object with its essential nature, i.e., the colour blue, is distinguished from other entities. Then, it is known as the notion ‘blue’, which is a mere provisional existence, through the conceptual thought of mental consciousness. However, for Śubhagupta, a coarse object such as something blue is only a mental error of conceptual construction. (shrink)

Some have argued that a subject has an inner awareness of its conscious mental states by virtue of the non-introspective, reflexive awareness that any conscious state has of itself. But, what exactly is it like to have a ubiquitous and reflexive inner awareness of one’s conscious states, as distinct from one’s outer awareness of the apparent world? This essay derives a model of ubiquitous inner awareness (UIA) from Sebastian Watzl’s recent theory of attention as the activity of structuring consciousness into (...) an experiential center and periphery. I develop Watzl’s theory into an account of UIA by suggesting that a subject is acquainted with its own conscious mental states through being reflexively aware of how these states are structured by attention into a unified subjective perspective. I favorably compare this Watzl-inspired account of UIA against other contemporary analytic and classical Buddhist accounts of reflexive awareness and subjective character, which variously ground the inner awareness of conscious states on their intrinsic phenomenal quality of “for-me-ness,” their affective/hedonic valence, or a subject’s disposition to introspect them. The Watzl-inspired account also accommodates possible counter-examples to Watzl’s theory posed by states of minimal phenomenal experience such as lucid dreamless sleep and non-dual meditative awareness.

The cross-cultural differences in epistemic intuitions reported by Weinberg, Nichols and Stich (2001; hereafter: WNS) laid the ground for the negative program of experimental philosophy. However, most of WNS’s findings were not corroborated in further studies. The exception here is the study concerning purported differences between Westerners and Indians in knowledge ascriptions concerning the Zebra Case, which was never properly replicated. Our study replicates the above-mentioned experiment on a considerably larger sample of Westerners (n = 211) and Indians (n = (...) 204). The analysis found a significant difference between the ethnic groups in question in the predicted direction: Indians were more likely to attribute knowledge in the Zebra Case than Westerners. In this paper, we offer an explanation of our result that takes into account the fact that replications of WNS’s other experiments did not find any cross-cultural differences. We argue that the Zebra Case is unique among the vignettes tested by WNS since it should not be regarded as a Gettier case but rather as a scenario exhibiting skeptical pressure concerning the reliability of sense-perception. We argue that skepticism towards perception as a means of gaining knowledge is a trope that is deeply rooted in Western epistemology but is very much absent from Classical Indian philosophical inquiry. This line of reasoning is based on a thorough examination of the skeptical scenarios discussed by philosophers of the Indian Nyaya tradition and their adversaries. (shrink)

The Problem of Perception is a pervasive and traditional problem about our ordinary conception of perceptual experience. The problem is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perceptual experience be what we ordinarily understand it to be: something that enables direct perception of the world? These possibilities of error challenge the intelligibility of our ordinary conception of perceptual experience; the major theories of experience are responses to this challenge.

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.

Is Buddhism’s attitude towards accepted forms of knowledge sceptical? Are Pyrrhonian scepticism and classical Buddhist scholasticism related in their respective applications and expressions of doubt? In what way and to what degree is Critical Buddhism an offshoot of modern scepticism? Questions such as these as well as related issues are explored in the present collection, which brings together examinations of systematic doubt in the traditions of Buddhism from a variety of perspectives. What results from the perceptive observations and profound analytical (...) insights of the seven essays is a rich and multi-faceted picture of two families of philosophical systems—scepticism and Buddhism—that seem both akin and at odds, both related and distant at the same time.

Although a number of authors have used diagrams extensively in their studies of Navya-Nyāya, they have done so to explain and illustrate concepts, not with the goal of reasoning with the diagrams themselves. Adherents of diagrammatic reasoning have made claims for its potential by pointing to key structural correspondences between diagrams and logical concepts, arguably lacking in sentential representations, and describing these relations using concepts such as “well matchedness” and “iconicity”. A canonical example of this iconicity is the use of (...) Euler diagrams to depict categorical syllogisms. Since the meaning of expressions in Indian logic differs in so many important ways from logic in the Western tradition, the use or adaptation of diagrams developed in the latter would seem to preclude iconicity. Thus, the development of diagrams which reflect the nature of inference in Navya-Nyāya, which centres on the anumāna inference schema, is motivated. In this paper we extend Ganeri’s method of depicting the Vaiśeṣika ontology with graphs to include syntax intended to expose the nature of anumāna. The diagrams are given a formal basis: i.e. abstract syntax, inference rules defined abstractly and a graph-theoretic semantics. These are the first formalised logical diagrams that aim to reflect the nature of the anumāna inference. This paper lays the way for further work in extending the formalism to cover more of Navya-Nyāya, and in exploring a dialogue between properties of the formalism and of Navya-Nyāya. (shrink)

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.

Two of the most important contributions that Bimal Krishna Matilal made to comparative philosophy are his doctoral dissertation The Navya-Nyāya Doctrine of Negation: The Semantics and Ontology of Negative Statements in Navya-Nyāya Philosophy and his classic: Perception: An Essay on Classical Indian Theories of Knowing. In this essay, we aim to carry forward the work of Bimal K. Matilal by showing how ideas in classical Indian philosophy concerning absence and perception are relevant to recent debates in Anglo-analytic philosophy. In particular, (...) we focus on the recent debate in the philosophy of perception centering on the perception of absence. In her Seeing Absence, Anya Farennikova argues for the thesis that we literally see absences. Her thesis is quite novel within the contexts of the traditions that she engages: analytical philosophy of perception, phenomenology, and cognitive neuroscience. In those traditions there is hardly any exploration of the epistemology of absence. By contrast, this is not the case in classical Indian philosophy where the debate over the ontological and epistemological status of absence is longstanding and quite engaging. In what follows, we engage Farennikova’s arguments, and those of John-Rémy Martin and Jérome Dokic in their response to her work. Using the work of Matilal, Bilimoria and Shaw we show that there are several engaging ideas that can be taken from Indian philosophy into the terrain explored by Farennikova, and Martin & Dokic. Our aim is to provide an updated comparative engagement on absence and its perception for the purposes of enhancing future discussions within global philosophy. However, we do not aim to do this merely by focusing on the history of primary texts or on twentieth century commentary on primary texts. Instead, we hope to show that the living tradition of Indian philosophy that Matilal embodied carries forward in his students and colleagues as they revive, revise, and extend Indian philosophy.

Assertion is fundamental to our lives as social and cognitive beings. By asserting we share knowledge, coordinate behavior, and advance collective inquiry. Accordingly, assertion is of considerable interest to cognitive scientists, social scientists, and philosophers. This paper advances our understanding of the norm of assertion. Prior evidence suggests that knowledge is the norm of assertion, a view known as “the knowledge account.” In its strongest form, the knowledge account says that knowledge is both necessary and sufficient for assertability: you should (...) make an assertion if and only if you know that it is true. The knowledge account has been rejected on the grounds that it conflicts with our ordinary practice of evaluating assertions. This paper reports four experiments that address an important objection of this sort, which focuses on a class of examples known as “Gettier cases.” The results undermine the objection and, in the process, provide further evidence for the knowledge account. The findings also teach some important general lessons about intuitional methodology and the curation of genres of thought experiment. (shrink)

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

In his *Bāhyārthasiddhikārikā (BASK), “Verses on the Establishment of the External Object”—extant only in Tibetan translation—Śubhagupta (720–780 CE), a philosopher connected with the logical-epistemological school of Buddhism, argues the reality of external objects of cognitions. In this article, I shall provide an account of Śubhagupta's theory of the cognitive process, as expressed in BASK 35–44, particularly in light of his view that the images (ākāra) of those objects do not appear in cognition. BASK is part of an internal Buddhist debate (...) over the reality of external supports of perceptions, wherein Śubhagupta disproves the views of thinkers like Diṅnāga and Vasubandhu. On the other hand, he is one of the main opponents addressed in the Bahirarthaparīkṣā (BAP) of the Tattvasaṅgraha (TS) by Śāntarakṣita (725–788 CE) and the Tattvasaṅgrahapañjikā (TSP) by Kamalaśīla (740–795 CE). Therein, the two authors, while demonstrating the absence of the characteristics of apprehended (grāhya) and apprehender (grāhaka) with regard to cognition, keenly refute his ideas and quote selected Sanskrit verses that can be identified as the original Sanskrit of stanzas in BASK. Accordingly, I shall examine Śubhagupta’s theory of the cognitive process in two steps: (i) analyzing the arguments that Śāntarakṣita and Kamalaśīla advance against him based on their interpretation of Śubhagupta’s views; and (ii) analyzing the arguments that he brings forward against his opponents (namely, Diṅnāga and Vasubandhu), by means of the investigation of BASK 35–44 in their original context.

Traditionally it has been thought that the moral valence of a proposition is, strictly speaking, irrelevant to whether someone knows that the proposition is true, and thus irrelevant to the truth-value of a knowledge ascription. On this view, it’s no easier to know, for example, that a bad thing will happen than that a good thing will happen (other things being equal). But a series of very surprising recent experiments suggest that this is actually not how we view knowledge. On (...) the contrary, people are much more willing to ascribe knowledge of a bad outcome. This is known as the epistemic side-effect effect (ESEE), and is a specific instance of a widely documented phenomenon, the side-effect effect (a.k.a. “the Knobe effect”), which is the most famous finding in experimental philosophy. In this paper, I report a new series of five experiments on ESEE, and in the process accomplish three things. First, I confirm earlier findings on the effect. Second, I show that the effect is virtually unlimited. Third, I introduce a new technique for detecting the effect, which potentially enhances its theoretical significance. In particular, my findings make it more likely that the effect genuinely reflects the way we think about and ascribe knowledge, rather than being the result of a performance error. (shrink)

This paper compares and contrasts two infinite regress arguments against higher-order theories of consciousness that were put forward by the Buddhist epistemologists Dignāga (ca. 480–540 CE) and Dharmakīrti (ca. 600–660). The two arguments differ considerably from each other, and they also differ from the infinite regress argument that scholars usually attribute to Dignāga or his followers. The analysis shows that the two philosophers, in these arguments, work with different assumptions for why an object-cognition must be cognised: for Dignāga it must (...) be cognised in order to enable subsequent memory of it, for Dharmakīrti it must be cognised if it is to cognise an object.

This article proposes a number of models to examine through which mechanisms a population of autonomous agents could arrive at a repertoire of perceptually grounded categories that is sufficiently shared to allow successful communication. The models are inspired by the main approaches to human categorisation being discussed in the literature: nativism, empiricism, and culturalism. Colour is taken as a case study. Although we take no stance on which position is to be accepted as final truth with respect to human categorisation (...) and naming, we do point to theoretical constraints that make each position more or less likely and we make clear suggestions on what the best engineering solution would be. Specifically, we argue that the collective choice of a shared repertoire must integrate multiple constraints, including constraints coming from communication. Key Words: autonomous agents; colour categorisation; colour naming; connectionism; cultural evolution; genetic evolution; memes; origins of language; self-organisation; semiotic dynamics; symbol grounding.

Goldstein reported multiple cases of failure to categorise colours in patients that he termed amnesic or anomic aphasics. These patients have a particular difficulty in producing perceptual categories in the absence of other aphasic impairments. We hold that neuropsychological evidence supports the view that the task of colour categorisation is logically impossible without labels.

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 will suggest that the ideas of Uddyotakara, the 6th century author of the Nyāya-Vārttika, may have been largely overlooked as a result of Jitendra Nath Mohanty’s and Bimal Krishna Matilal’s influential works on Indian epistemology. Crucial to Mohanty’s and Matilal’s portrayals of Indian epistemology is the thesis that the pramāṇa theory incorporates a sort of causal theory of knowledge. The writers of pramāṇa-śastra, they argue, agreed that at the end of the day, knowledge comes down to (...) an ‘inner’ occurrence, a temporally individuated cognitive episode, and that consequently—the pramāṇa—the most relevant factor affecting knowledge acquisition and the ultimate justification of knowledge acquisition—are “the cluster of phenomena that converge to bring such a cognitive episode about”. I will argue, on the other hand, based on a discussion Uddyotakara conducts at the beginning of the introductory chapter of his work, which I believe to be of crucial importance, that causal factors play only a marginal role in his theory of knowledge and that he claims the pramāṇa to be dependent on samartha-pravṛtti—the habitual, customary and expected procedures or ways of attaining a goal—rather than on their causal antecedents. I will moreover suggest a reading of the pramāṇa of sense-perception, inference and analogy as action-based. (shrink)

But under the requirement of philosophic consistency, and the impact of the perfectly valid reflection that experience is always my experience, and never part of some object independent of me, the world shrinks to the extension of my experience only, and I am left with bundles of my sensations. What are the natural consequences of such an epistemological sophistication?One plausible and natural reaction is what one might call the ‘Indian’ one. It runs roughly as follows: my experience of the world (...) is, alas, only my experience. It is not ‘the real’. Moreover, the world disclosed in my experience is one of misery, precariousness, insecurity, which ends in old age and death and within which no secure, reliable, undeceptive goods can be found. The flux and precariousness which make it so unhappy a place, also make it most ill-suited to be an object of knowledge. — E. Gellner (1974: 114). (shrink)

When J. L. Austin introduced two “shining new tools to crack the crib of reality”—the theory of performative utterances and the doctrine of infelicities—he could not have imagined that he was also about to inaugurate a shining new industry in the philosophy of the social sciences. But with its evident concern for the features to which “all acts are heir which have the general character of ritual or ceremonial,” Austin’s theory soon became indispensable in the analysis of ritual, linguistic and (...) every kind of social action. While Indianists such as Frits Staal, Bimal Matilal and David Seyfort Ruegg have made good use of the work of Austin and his “ordinary language” school, it is Quentin Skinner who has attempted to turn Austin’s insights into a general “theory and method” for the study of intellectual cultures. The question I want to address in this paper has to do with the applicability of Skinnerian techniques to the study of literary and intellectual Sanskrit culture in premodern India. If not all of Skinner’s methods transfer to the new context, identification of the points at which they breakdown helps to clarify the distinctive contours of Indian intellectual history, and suggests appropriate methodological innovation.

In this article, I explore the encounter of the Mādhva philosopher Vyāsatīrtha with the works of the Navya-Naiyāyika Gaṅgeśa Upādhyāya. The article is based on original translations of passages from Vyāsatīrtha’s Nyāyāmr̥ta and Tarkatāṇḍava. Philosophically, the article focuses on the issue of empty-terms/nonexistent entities, particularly in the context of the theory of inference. I begin by outlining the origin of the Mādhva and Nyāya positions about these issues in their respective analyses of perceptual illusion. I then contrast the role of (...) Gaṅgeśa’s thought in the Nyāyāmr̥ta and Tarkatāṇḍava and show how Vyāsatīrtha responds to Gaṅgeśa’s ideas in different ways in those texts. I conclude with a discussion of how Vyāsatīrtha defends the Mādhva theory of “substrate-free” qualities against Gaṅgeśa in order to show that we can think and make valid inferences about nonexistent things.

This chapter explores how perspectives on science drawn from Indian experiences can contribute to the interface between history and philosophy of science (HPS) and science education (SE). HPS is encoded in science texts in the various presuppositions that underlie both the content and the way the content is presented. Thus, a deeper engagement with contemporary work in HPS will be of great significance to science teaching. By drawing on the notion of multicultural origins of science as well as redefining the (...) nature of science debate by invoking the Indian engagement with science, this chapter aims to make both HPS and SE more sensitive to other cultural understandings of science and scientific method. The last two sections describe ways of drawing on the Indian philosophical traditions that could be relevant for contemporary debates, such as constructivism and teaching critical thinking, in science education.
