In defending the teaching of emptiness, Bhāvaviveka offers some very strange arguments, which initially may appear so weak that we may be hard pressed to understand how anyone could endorse them. To make sense of these passages, it is helpful to compare them to an argument found in the writings of the Naiyāyika Uddyotakara. These arguments have a certain formal feature which makes them count as valid from the point of view of the rules and norms of some forms of (...) Indian logic. Once we understand the logical structure of the arguments offered by Uddyotakara and Bhāvaviveka, we will not only have a better grasp on their philosophical views, but we will also be in a better position to understand how and why those views were rejected by later figures in the Indian tradition, such as Dharmakīrti and Śāntarak⋅ita.

This paper is a study of debate practices as seen in the Nyāyasūtra and a number of commentaries. It concentrates on the ‘Points of Defeat ’, i.e., those occasions that if met in debate would entail defeat. The conditions under which a debater would meet with defeat were discussed widely in India and have also attracted considerable attention from modern scholars. In order to better understand this subject, use is made of some of the intuitions about language and conversation that (...) we owe to the philosopher H. P. Grice as well as of some recent theoretical advances in argumentation theory and informal logic, particularly of those most influenced by Grice’s thought. The Points of Defeat are studied both individually and as a group and it is shown that they point towards the practice of debating as being a rational, cooperative and goal-directed activity.

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.

2022 CHOICE Outstanding Academic Title The purpose of this book is to fill a gap in contemporary mystical studies: an overview of the basic ways to approach mystical experiences and mysticism. It discusses the problem of definitions of “mystical experiences” and “mysticism” and advances characterizations of “mystical experiences” in terms of certain altered states of consciousness and “mysticism” in terms of encompassing ways of life centered on such experiences and states. Types of mystical experiences, enlightened states, paths, and doctrines are (...) discussed, as is the relation of mystical experiences and mysticism to religions and cultures. The approaches of constructivism, contextualism, essentialism, and perennialism are presented. Themes in the history of the world’s major mystical traditions are set forth. Approaches to mystical phenomena in sociology, psychology, gender studies, and neuroscience are introduced. Basic philosophical issues related to whether mystical experiences are veridical and mystical claims valid, mystics’ problems of language, art, and morality are laid out. Older and newer comparative approaches in religious studies and in Christian theology are discussed, along with postmodernist objections. The intended audience is undergraduates and the general public interested in the general issues related to mysticism. (shrink)

In 2001, W. Carnielli and Marcos considered a 3-valued logic in order to prove that the schema ϕ ∨ (ϕ → ψ) is not a theorem of da Costa’s logic Cω. In 2006, this logic was studied (and baptized) as G'3 by Osorio et al. as a tool to define semantics of logic programming. It is known that the truth-tables of G'3 have the same expressive power than the one of Łukasiewicz 3-valued logic as well as the one of Gödel (...) 3-valued logic G3. From this, the three logics coincide up-to language, taking into acccount that 1 is the only designated truth-value in these logics. -/- From the algebraic point of view, Canals-Frau and Figallo have studied the 3-valued modal implicative semilattices, where the modal operator is the well-known Moisil-Monteiro-Baaz Δ operator, and the supremum is definable from this. We prove that the subvariety obtained from this by adding a bottom element 0 is term-equivalent to the variety generated by the 3-valued algebra of G'3. The algebras of that variety are called G'3-algebras. From this result, we obtain the equations which axiomatize the variety of G'3-algebras. Moreover, we prove that this variety is semisimple, and the 3-element and the 2-element chains are the unique simple algebras of the variety. Finally an extension of G'3 to first-order languages is presented, with an algebraic semantics based on complete G'3-algebras. The corresponding soundness and completeness theorems are obtained.

Buddhist philosophers have investigated the techniques and methodologies of debate and argumentation which are important aspects of Buddhist intellectual life. This was particularly the case in India, where Buddhism and Buddhist philosophy originated. But these investigations have also engaged philosophers in China, Japan, Korea and Tibet, and many other parts of the world that have been influenced by Buddhism and Buddhist philosophy. Several elements of the Buddhist tradition of philosophy are thought to be part of this investigation. -/- There are (...) interesting reasoning patterns discernible in the writings of Buddhist philosophers. For instance, the Mādhyamika philosopher Nāgārjuna presents arguments for the emptiness of all things in terms of catuṣkoṭi (four ‘corners’: roughly speaking, truth, false, both, neither). There are also the Indian vāda (debate) literature and Tibetan bsdus grwa (collected topics) that list techniques of debates. -/- The main interest here is the tradition of Buddhist philosophy, sometimes referred to as Pramāṇavāda, whose central figures are Dignāga (approx. 480–540 CE) and Dharmakīrti (6th– 7th CE). This philosophy is understood to be the Buddhist school of logic-epistemology. ‘Pramāṇavāda’ is not a doxographical term traditionally used to refer to a recognised school of Buddhist philosophy. It is a conventional term that is sometimes used in modern literature. Nevertheless, in what follows, we think of it as a tradition within Buddhist philosophy and ‘Buddhist logic’ refers to what is developed in this tradition. -/- Buddhist logicians have systematically analysed the kind of reasoning involved in acquiring knowledge. They hold that there are valid ways to reason that are productive of knowledge. In what follows, some of the main elements of their analyses will be described. Note, however, that, while exegetical studies of Buddhist texts are important, we must step back from them and consider what is involved in taking a Buddhist approach to logic in light of modern formal logic. This analysis will be done against the backdrop of the contemporary literature on logic and related subjects in contemporary philosophy to make sense of the logical studies by Buddhist logicians.

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)

The tradition of Nyāya philosophy centers on a dispassionate quest for truth which is simultaneously connected to soteriological and epistemic aims. This article shows how Vācaspati Miśra brings together the soteriological concept of dispassion with the discourse practices of debate, as a response to Buddhist criticisms in Dharmakīrti’s Vādanyāya. He defends the Nyāyasūtra’s stated position that fallacious reasoning is a legitimate means for a debate, under certain circumstances. Dharmakīrti argues that such reasoning is rationally ineffective and indicates unvirtuous qualities. For (...) Vācaspati, fallacies are a way to prevent the spread of morally weighty falsehoods when no other method is available to a debater. After showing textual relationships between Vācaspati’s defense and Dharmakīrti’s earlier criticism, it evaluates their arguments, concluding that Vācaspati’s position involves irresolvable tensions with other Nyāya commitments.

: In this essay I set out the case for why mindfulness meditation should be included in critical thinking education, especially with respect to educating people about how to argue with one another. In 1, I introduce to distinct mind sets, the critical mind and the meditative mind, and show that they are in apparent tension with one another. Then by examining the Delphi Report on Critical Thinking I show how they are not in tension. I close 1 by examining (...) some recent work by Mark Battersby and Jeffery Maynes on expanding out critical thinking education to be inclusive of cognitive science and decision making. I argue that their arguments for expanding critical thinking education ultimately lead to considering the relevance of meditation in critical thinking. In 2, I examine work on critical thinking by Harvey Siegel and Sharon Bailin in order to draw out different conceptions of critical thinking both from a theoretical point of view as well as a pedagogical point of view. In 3, I present criteria for selecting a form of meditation that should be taught in critical thinking courses; I argue that mindfulness meditation deriving from the Buddhist tradition satisfies the relevant criteria. I then present research from contemporary cognitive neuroscience and psychology about the benefits of mindfulness meditation as it relates to the prospects of including it in critical thinking. In 4, I consider a recent study by Noone and Hogan that suggests that mindfulness meditation does not improve a person’s ability to think critically. I argue that while the study is important, there are substantial reasons for thinking that further studies should be done, as the authors themselves conclude. In 5, I move on to the issue of how meditation can be useful for improving performance in one important area of critical thinking: mitigating stereotype threat. My focus here is on examining the hypothesis that stereotype threat effects performance in critical thinking, and that negative impacts from stereotype threat can be mitigated by meditation. In 6, I summarize my argument for including meditation into critical thinking education, and close by discussing three important objections. (shrink)

Buddhist philosophers have developed a rich tradition of logic. Buddhist material on logic that forms the Buddhist tradition of logic, however, is hardly discussed or even known. This article presents some of that material in a manner that is accessible to contemporary logicians and philosophers of logic and sets agendas for global philosophy of logic.

According to the argumentative theory of reasoning, humans have evolved reasoning abilities for argumentative purposes. This implies that some reasoning skills should be universals. Such a claim seems to be at odd with findings from cross-cultural research. First, a wealth of research, following the work of Luria, has shown apparent difficulties for illiterate populations to solve simple but abstract syllogisms. It can be shown, however, that once they are willing to accept the pragmatics of the task, these participants can perform (...) at or near ceiling. Second, historical, sociological and anthropological research has been used to claim that some Eastern cultures have not developed argumentation. These claims are the result of oversimplifications and of a selective view of the data. A closer looks reveals instead very elaborate forms of argumentation, in Chinese culture particularly. Third, cross-cultural psychologists have carried out an extensive research program aimed at showing that Easterners do not rely on the principle of non-contradiction and that they use holistic rather than analytic thinking. A review of these experiments shows that no qualitative difference emerges in the way Easterners and Westerners deal with argumentation and that in the proper context both populations can easily have recourse to holistic or analytic thinking. It is possible to conclude from this critical review that the reasoning skills involved in argumentation seem to be universal even though they can be used in different ways in various cultural contexts.

B.K.Matilal, and earlier J.F.Staal, have suggested a reading of the `Nyaya five limb schema' (also sometimes referred to as the Indian Schema or Hindu Syllogism) from Gotama's Nyaya-Sutra in terms of a binary occurrence relation. In this paper we provide a rational justification of a version of this reading as Analogical Reasoning within the framework of Polyadic Pure Inductive Logic.

Arthāpatti does not depend on observation of pervasion or background belief. It is certain in the sense that when S cognizes P through postulation, no other epistemic instrument would invalidate P. The Naiyāyika tries to reduce postulation to anumāna and/or tarka. I shall argue that it is neither. Due to its explanatory role, one may think that postulation plays an essential role in lakṣaṇā or indication. But this too is a misconception. Both tarka and lakṣaṇā depend on observation and background (...) knowledge. Neither of them has the epistemic certainty postulation enjoys. I think, due to its observation-independent nature and certainty, postulation can be seen as the source of the knowledge of the truths of reason. (shrink)

The evaluation of arguments was not the sole concern of logicians in ancient India. Early Nyāya and the later Navya-Nyāya provide an interesting example of the interaction between logic and ontology. In their attempt to develop a kind of property-location logic Naiyāyikas had to consider what kind of restrictions they should impose on the residence relation between a property and its locus. Can we admit circular residence relations or infinitely descending chains of properties, each depending on its successor as its (...) locus? Early Naiyāyikas and to some extent also Navya-Naiyāyikas regard these phenomena as a kind of absurdity and they want to rule them out. Their intuitions about properties are close to well-founded systems of set theory, whereas the author of the Navya-Nyāya work Upādhidarpaṇa is a proponent of a non-well-founded property concept. Despite certain similarities with sets properties are still regarded as intensional objects in Navya-Nyāya. In the pre.. (shrink)

Vedantas y budistas han llevado adelante una disputa acerca de los medios válidos para acceder al conocimiento (pramānas) que, como afrma Matilal, no puede dejar de ser considerada como parte de la historia global del conocimiento. La doctrina sistematizada por Gaṅgeśa en su Tattvacintamani, que originalmente admitía cuatro pramānas (percepción, inferencia, analogía y testimonio) fue sufriendo sucesivas modifcaciones y perfeccionamientos como respuesta a las objeciones realizadas principalmente por los budistas.

For Jizang (549−623), a prominent philosophical exponent of Chinese Madhyamaka, all things are empty of determinate form or nature. Given anything X, no linguistic item can truly and conclusively be applied to X in the sense of positing a determinate form or nature therein. This philosophy of ontic indeterminacy is connected closely with his notion of the Way (dao), which seems to indicate a kind of ineffable principle of reality. However, Jizang also equates the Way with nonacquisition as a conscious (...) state of freedom from any attachment and definite understanding whatsoever. The issue then becomes pressing as to how we are to understand Jizang's notion of the Way. Does it indicate some metaphysical principle or reality? Is it actually a skilful expedient to lead one to the consummate state of complete spiritual freedom? How is this issue related to Jizang's conception of ontic indeterminacy? In this book chapter, I examine Jizang's key writings in an attempt to clarify his ontological position. (shrink)

This essay in the comparative metaphysic of nothingness begins by pondering why Leibniz thought of the converse question as the preeminent one. In Eastern philosophical thought, like the numeral 'zero' (śūnya) that Indian mathematicians first discovered, nothingness as non-being looms large and serves as the first quiver on the imponderables they seem to have encountered (e.g., 'In the beginning was neither non-being nor being: what was there, bottomless deep?' RgVeda X.129). The concept of non-being and its permutations of nothing, negation, (...) nullity, etc., receive more sophisticated treatment in the works of grammarians, ritual hermeneuticians, logicians, and their dialectical adversaries variously across Jaina and Buddhist schools. The present analysis follows the function of negation/the negative copula, nãn, and dialetheia in grammar and logic, then moves onto ontologies of non-existence and extinction and further suggestive tropes that tend to arrest rather than affirm the inexorable being-there of something. After a discussion of interests in being (existence), non-being and nothingness in contemporary metaphysics, the article examines Heidegger’s extensive treatment of nothingness in his 1929 inaugural Freiburg lecture, 'Was ist Metaphysik?', published later as 'What is Metaphysics?' The essay however distances itself from any pretensions toward a doctrine of Metaphysical Nihilism. (shrink)

In classical India, Jain philosophers developed a theory of viewpoints ( naya-vāda ) according to which any statement is always performed within and dependent upon a given epistemic perspective or viewpoint. The Jainas furnished this epistemology with an (epistemic) theory of disputation that takes into account the viewpoint in which the main thesis has been stated. The main aim of our paper is to delve into the Jain notion of viewpoint-contextualisation and to develop the elements of a suitable logical system (...) that should offer a reconstruction of the Jainas’ epistemic theory of disputation. A crucial step of our project is to approach the Jain theory of disputation with the help of a theory of meaning for logical constants based on argumentative practices called dialogical logic . Since in the dialogical framework the meaning of the logical constants is given by the norms or rules for their use in a debate, it provides a meaning theory closer to the Jain context-sensitive disputation theory than the main-stream formal model-theoretic semantics.

The aim of this essay is to clarify Nāgārjuna’s use of the term pratijñā in verse 29 of the Vigrahavyāvartanī as situated in its contemporaneous thriving debate culture. In contrast to the standard formulation, which interprets the term pratijñā as a reference to the thesis of śūnyatā proffered by Nāgārjuna in the Mūlamadhyamakakārikā, an examination of the debate culture in, and leading up to, second-century CE India shows that the term pratijñā refers to the first of five steps within the (...) Nyaya five-membered syllogism as it functions within a vitaṇḍā form of debate. Through an examination of the context in which this verse was written, the association made between Nāgārjuna’s use of pratijñā in the VV and śūnyatā within other texts becomes dislodged, thereby demonstrating the inadequacy of the standard formulation and the need for a revised understanding of the intent of the VV.

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.

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.

It is often remarked that Indian logic (IL) has no conception of necessity. But what kind of necessity is absent in this system? Logical necessity is presumably absent: the structure of the logical argument in IL is often given as a reason for this claim. However even a cursory understanding of IL illustrates an abiding attempt to formulate the idea of necessity. In Dharmakīrti's classification of inferences, one can detect the formal process of entailment in the inferences arising from class (...) inclusion. In Western philosophy, Leibniz's invocation of 'contingent necessity' as distinguished from the 'necessary necessity' is part of a tradition that finds value in the idea of contingent necessity. In contemporary philosophy, this has been championed by Armstrong, specifically in the context of understanding the necessity inherent in scientific laws. In IL, the analysis of 'invariable concomitance' (vyāpti) is of crucial importance and its definitions are very complex. This paper argues how vyāpti can be understood in terms of contingent necessity and also how the complex definitions can be interpreted as an attempt to define contingent necessity in terms of 'logical' necessity.

In this paper, I explore a debate between some Indian Buddhist schools regarding the nature of the underlying tendencies or anusaya-s. I focus here primarily on the ninth chapter of Kathāvatthu’s representation of a dispute about whether an anusaya can be said to have intentional object. I also briefly treat of Vasubandhu’s defense of the Sautrāntika view of anuśaya in the opening section of the fifth chapter his Abhidharmakośabhāṣyam. Following Vasubandhu, I argue against the Thervādin Abhidharmikas that the underlying tendencies (...) (anusaya-s) can be identified with their active manifestations (pariyuṭṭhāna). Etymologically, the notion of anusaya denotes a kind of latency, dormancy or otherwise ‘below the surface’ propensity. It can literally be translated as ‘that which lies or dwells beneath or alongside’. I will translate the term as ‘underlying tendency’, but philosophically speaking, it is most important to understand that the notion of anusaya refers to dispositions that condition current experience in a tacit way. The task of a philosophical account of the anusaya-s is to explain how their implicit conditioning influence shapes occurrent mental activity. The Indian Buddhist philosophers exercised an enormous amount of energy in attempting to explain this relation. A thorough examination of this dialectic has two important fruits to bear. The first is that the Buddhists can help us explain in precise detail how the mind is affectively layered. That is, they have a plausible account of how the mind is both responsive in real time to the objects it encounters in the world, while at the same time being tacitly conditioned by its own history of affective bias. Indeed, as we will see, the Buddhists were deeply concerned with how processes of affective bias were operating at the deepest levels of the mind and how we ought to conceive of their influence on our ordinary processes of perception and cognition. Second, this local position within the Buddhist milieu is indicative of a wider propensity in Buddhist philosophy to blend analyses of affectively-biased intentions and causation. I submit that this blending could be helpful in a more global for contemporary discussions of the mind in philosophy and science. (shrink)

The introduction clarifies the importance of the commentary and explores what can be learned from it.

The exhaustive explications on jāti-s (sophisticated ripostes) and their seemingly chaotic arrangement in early Indian philosophical texts arouses an expectation for a systematic taxonomy or typology. Such taxonomy would enormously increase the heuristic value of the list of jāti-s. The present article aims to reveal some interpretational problems relevant to the understanding of the jāti-s’ historical development, as well as the theoretical implications of their typology. Focusing historically on the early texts of debate manuals of Nyāya and Buddhist circles, this (...) article will excavate and explicate the vague and the obvious attempts to establish a typology of jāti-s. Given that Diṅnāga was the philosopher who shifted the history of Indian philosophy into the era of macro theory by integrating ontology and epistemology into a general system, the minimal changes of the order of the jāti-s in the list given in the Pramāṇasamuccaya, in contrast to the one found in the Nyāyamukha, will be interpreted as a paradigm shift. The rearrangement of the jāti list in the Pramāṇasamuccaya represents the paradigm shift from the debate (vāda) manual to the epistemological (pramāṇa) treatise, confirming Frauwallner’s ideas regarding the development of Diṅnāga’s thought.

All individual terms listed as jāti-s (sophisticated ripostes) in Nyāyasūtra V a 1 have the peculiar uniform ending -sama. The interpretation of this ending here reveals a greater nuance of meaning than the hitherto customary understanding of it. It will be demonstrated that the observable semantic difference is due to a historical shift of signification as a result of an enlarging and systematizing of the thematic group of jāti-s. In this paper, I examine relevant text material, including two very important (...) manuscripts of the Nyāyabhṣya to show this semantic difference. The understanding gained by this analysis will help to trace the historical development of the complex of jāti-s within the larger context of the ancient Indian tradition of debate. (shrink)

The technical term “ tarka ” in the Nyāya tradition is the object of the present investigation. Diverse texts including Buddhist ones exhibit a negative estimation of activities using tarka . In contrast, more often than not, later treatises dealing with logico-epistemic problems, especially certain Naiyāyika works, identify the methodological peculiarity of Nyāya with tarka . Such an ambivalent attitude toward tarka can be understood in a coherent way if the essential features of tarka that gave rise to it can (...) be grasped. Starting from the Nyāyasūtra 1.1.40 and the explanation given in the Nyāyabhāṣya on it, the present researcher sorted out three characteristic features of tarka in the early Nyāya tradition. These three features focus on the main feature of tarka : namely, reflective analysis without requiring further factual information on the object of investigation. Based on this, the present researcher critically reviewed what promoted an understanding of tarka as a reductio ad absurdum argument or an a priori reasoning. Furthermore, certain passages from the Nyāyamañjarī , Nyāyakalikā , and Tarkasaṅgraha were examined to demonstrate that the present researcher’s interpretative understanding of tarka was adequate for explaining the usage of this term in a broad sense, with positive connotations.

The present essay aims to throw light on the study of dialectical thinking from a cultural-historical perspective. Different forms of dialectic are articulated as ideal types, including the Greek dialectic, the Hegelian dialectic, the contemporary German negative dialectic, the Chinese dialectic, and the Indian negative dialectic. These influential cultural products in the history of the East and the West, articulated as ideal types, serve as constellations that could facilitate further empirical studies on dialectical thinking. An understanding of the complexity of (...) these constellations reveals the pitfalls of investigating dialectical thinking without an appropriate conceptualization of the research target. With the ideal types of dialectic as "figure," and Vygotsky's thesis of the cultural-historical origin of higher psychological processes as "ground," we explore possibilities for further lines of inquiry on dialectical thinking. Adhering to the Scribnerian multilevel scheme that reconstructs Vygotsky's thesis, and returning to the core ideas of Vygotsky himself, we discover new, meaningful questions about the study of dialectical thinking. In the research area of "culture and cognition," consideration of a cultural-historical perspective appears to be both necessary and promising. (shrink)

In this paper I propose a naturalist account of the Buddhist epistemological discussion of svasaṃvitti ('self-awareness', 'self-cognition') following similar attempts in the domains of phenomenology and analytic epistemology. First, I examine the extent to which work in naturalized epistemology and phenomenology, particularly in the areas of perception and intentionality, could be profitably used in unpacking the implications of the Buddhist epistemological project. Second, I argue against a foundationalist reading of the causal account of perception offered by Dignāga and Dharmakīrti. Finally, (...) I argue that it is possible to read Dignāga's (and following him Dharmakīrti's) treatment of svasaṃvitti_ as offering something like a phenomenological account of embodied self-awareness. (shrink)

Nāgārjuna’s doctrine of emptiness, his ideas on “two truths” and language, and his general method of arguing are presented clearly by him and can be stated without paradox. That the dialetheists today can restate his beliefs in paradoxical ways does not mean that Nāgārjuna argued that way; in fact, their restatements misrepresent and undercut his arguments.

Although rhetoric is not a category of ancient Indian philosophy, this paper argues that Śāntarakṣita and Kamalaśīla, 2 eighth-century Indian Buddhist philosophers, can nonetheless be seen to embrace a rhetorical conception of rationality. That is, while these thinkers are strong proponents of rational analysis and philosophical argumentation as tools for attaining certainty, they also uphold the contingent nature of all such processes. Drawing on the categories of the New Rhetoric, this paper argues that these Buddhist thinkers understand philosophical argumentation to (...) be directed at a universal audience of rational beings, where this universal audience is not an actual audience but a rhetorical one constructed through the author’s particular and historically contingent conception of what counts as rational. A reception theory of rationality is one that holds that the rationality of an argument depends upon its acceptance by a rational audience. When philosophers recognize the historically contingent nature of what counts as rational, they can embrace a reception theory of rationality that neither reduces the rational to mere opinion nor restricts it to a single, absolute, and timeless standard.

Ethos and logos of the Jain thought and practice is based on reality perceived by senses. Atheistic roots of Jain Dharm have nourished growth, maintained viability and vitality, and kept it relevant for over the last five millennia. Unlike Judeo-Christian-Islam or Brahminical faith, it does not rely on omniscient supreme or god. Its atheistic and anti-theistic thrust is generally known, yet its followers do not call themselves Nastik. They emphasize action-consequence relations as guide for successful behaviors with ethical conduct. The (...) basis of their arguments follows from the Jain logic of evidence based inference with multiple orthogonal affirmed assertions. It conserves information by acknowledging the remaining doubt in an inference. It does not assume binary complementation to force closure for deduction with incomplete knowledge which leads to self-reference and loss of information. This approach offers a rational and practical alternative to conundrum of western atheism even though its arguments are logical and consistent with available evidence. It also obviates need to extract religious morality from social mores. Objective truth and knowledge of established generalizations is necessary but not sufficient for subjective searches to shape desires and for what the futureought to be. (shrink)

While discourse on the relation between Christianity and science has a long history, it has only been in the last century that Buddhists and Buddhist scholars have begun to consider the relation between their own religious tradition and the promises and challenges of modern science. This does not mean that there has not been a long history of a relation between Buddhism and the sciences. However, rarely has that relation been conceived of in terms of “discourse on religion and science” (...) as such. As a result, much of the recent work done in the area of science and religion, though significant in its own right, inadequately considers many core Buddhist concerns.

This article examines the emergence of the Nyāya distinction between vāda and jalpa as didactic-scientific and agonistic-sophistical forms of debate, respectively. Looking at the relevant sutras in Gautama’s Nyāya-sūtra (NS 1.2.1-3) in light of the earlier discussion of the types of debate in Caraka Saṃhitā 8, the article argues that certain ambiguities and obscurities in the former text can be explained on the hypothesis that the early Nyāya presupposed an agonistic understanding of vāda similar to what we find in Caraka.

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)

The little versified treatise on the elements of Buddhist logic, often referred to as the Hetucakraḍamaru, is usually attributed to Dignāga. It is only available in a Tibetan translation and quotations from a few of its verses are extant in Sanskrit sources. On the basis of a novel interpretation that is based on a critical edition of the text, we argue that there is a good reason why its title was Hetucakraḍamaru - a ḍamaru is a two-headed drum. The “heads” (...) of the drum are circular and they refer to the sapakṣa and vipakṣa conditions of the logical reason. These “wheels” can be turned clock-wise and counter clock-wise. The nine positions that are located on the wheels do remind one of a dharmacakra, which has a center and eight positions that are placed around it as if it were a compass. We illustrate our interpretation of the text by means of various diagrams. (shrink)

This paper examines the role of doubt in the classification of inferential reasons in Dharmottara’s Nyāyabinduṭīkā, and in the works of his Nyāya rivals Keśavamiśra and Jayantabhaṭṭa. As deeply systematic thinkers, larger themes in these philosophers’ metaphysics directly determine the more local issues in epistemology and inferential theory, helping to explain, and show the significance of, the differences in their accounts of inferential reasons. For Keśava, an ontology which includes real universals allows for an externalist, reliabilist epistemology, on which the (...) conditions for a genuine inferential reason can be stated in an absolute manner. For Dharmottara, on the other hand, an ontology in which mentally constructed universals are imposed upon real particulars leads to greater dependency on the cognising agent, such that the triple conditions for the inferential reason are formulated in a cogniser-relative way. These differences lead to a more restrictive list of acceptable reasons on Dharmottara’s part, which excludes cases involving doubt. (shrink)
