The catuṣkoṭi or tetralemma is an argumentative figure familiar to any reader of Buddhist philosophical literature. Roughly speaking it consists of the enumeration of four alternatives: that some propositions holds, that it fails to hold, that it both holds and fails to hold, that it neither holds nor fails to hold. The tetralemma also constitutes one of the more puzzling features of Buddhist philosophy as the use to which it is put in arguments is not immediately obvious and certainly not (...) uniform: sometimes one of the four possibilities is selected as ‘the right one’, sometimes all four are rejected, sometimes all four are affirmed. It seems that this confusion is only exacerbated by the plethora of treatments we find in the modern commentarial literature, many of which try to analyze the tetralemma by recourse to notions of modern logic. Despite some important work done during the last decades a comprehensive study of the origin and development of the catuṣkoṭi from its use in the earliest Buddhist literature up to its later employment in the Buddhist philosophical works of Tibet, China, and Japan remains yet to be written. The present paper is obviously not intended to fill this gap, but has the specific objective of giving an interpretation of Nāgārrjuna’s employment of the tetralemma which makes both logical sense and is in accordance with his general philosophical position.

This paper examines the role of pramāṇa in Jayānanda’s commentary to Candrakīrti’s Madhyamakāvatāra. As the only extant Indian commentary on any of Candrakīrti’s works (available only in Tibetan translation), written in the twelfth century when Candrakīrti’s interpretation of Madhyamaka first became widely valued, Jayānanda’s Madhyamakāvatāraṭīkā is crucial to our understanding of early Prāsaṅgika thought. In the portions of his text examined here, Jayānanda offers a pointed critique of both svatantra inferences and the broader Buddhist epistemological movement. In developing this critique, (...) he cites at length Candrakīrti’s Prasannapadā treatment of svatantra, and so comes to comment on the locus classicus for the Svātantrika-Prāsaṅgika distinction. For Jayānanda, svatantra inferences are emblematic of the Dignāga-Dharmakīrti epistemological tradition, which asserts an unwarranted validity to human cognition. As such, Nāgārjuna’s philosophy admits neither svatantra inference, nor pramāṇa (as “valid cognition”) more generally. Instead, Jayānanda argues for Nāgārjuna’s “authority” (pramāṇa) as our prime means for knowing reality. Jayānanda’s account of authority offers a helpful counterbalance to the current trend of portraying Prāsaṅgika Madhyamaka as a form of skepticism. (shrink)

In early Buddhist logic, it was standard to assume that for any state of a ff airs there were four possibilities: that it held, that it did not, both, or neither. This is the catuskoti (or tetralemma). Classical logicians have had a hard time mak­ing sense of this, but it makes perfectly good sense in the se­mantics of various paraconsistent logics, such as First Degree Entailment. Matters are more complicated for later Buddhist thinkers, such as Nagarjuna, who appear to suggest (...) that none of these options , or more than one, may hold. The point of this paper is to examine the matter, including the formal logical machinery that may be appropriate. (shrink)

There is unanimous agreement that Nāgārjuna (ca 150–250 AD) is the most important Buddhist philosopher after the historical Buddha himself and one of the most original and influential thinkers in the history of Indian philosophy. His philosophy of the “middle way” (madhyamaka) based around the central notion of “emptiness” (śūnyatā) influenced the Indian philosophical debate for a thousand years after his death; with the spread of Buddhism to Tibet, China, Japan and other Asian countries the writings of Nāgārjuna became an (...) indispensable point of reference for their own philosophical inquiries. A specific reading of Nāgārjuna's thought, called Prāsaṅgika-Madhyamaka, became the official philosophical position of Tibetan Buddhism which regards it as the pinnacle of philosophical sophistication up to the present day.

Original in content and approach, Philosophy in Classical India focuses on the rational principles of Indian philosophical theory, rather than the mysticism usually associated with it. Ganeri explores the philosophical projects of a number of major Indian philosophers and looks into the methods of rational inquiry deployed within these projects. In so doing, he illuminates a network of mutual reference and criticism, influence and response, in which reason is simultaneously used constructively and to call itself into question.

This paper considers the philosophical interpretation of the concept of svabhāva, sometimes translated as 'inherent existence' or 'own-being', in the Madyamaka school of Buddhist philosophy. It is argued that svabhāva must be understood as having two different conceptual dimensions, an ontological and a cognitive one. The ontological dimension of svabhāva shows it to play a particular part in theories investigating the most fundamental constituents of the world. Three different understandings of svabhāva are discussed under this heading: svabhāva understood as essence, (...) as substance, and as the true nature of phenomena (absolute svabhāva). The cognitive dimension shows svabhāva as playing an important rôle in our everyday conceptualization of phenomena. Svabhāva is here seen as a superimposition (samāropa) which the mind projects onto the world. (shrink)

The logical analysis of Nāgārjuna’s catuṣkoṭi has remained a heated topic for logicians in Western academia for nearly a century. At the heart of the catuṣkoṭi, the four corners’ formalization typically appears as: A, Not A, Both, and Neither. The pulse of the controversy is the repetition of negations in the catuṣkoṭi. Westerhoff argues that Nāgārjuna in the Mūlamadhyamakakārikā uses two different negations: paryudāsa and prasajya-pratiṣedha. This paper builds off Westerhoff’s account and presents some subtleties of Nāgārjuna’s use of these (...) negations regarding their scope. This is achieved through an analysis of the Sanskrit and Tibetan Madhyamaka commentarial tradition and through a grammatical analysis of Nāgārjuna’s use of na and a- within a diverse variety of the catuṣkoṭi within the Mūlamadhyamakakārikā.

In the Bṛhadāraṇyaka Upaniṣad, one of the principal Upaniṣads, we find a venerable and famous story where the god Prajāpati separately instructs three groups of people (gods, humans, and demons) simply by uttering the syllable “Da.” In this paper, our concern is not with ethics but theories of meaning and interpretation: How can all divergent interpretations of a single expression be correct, and, indeed, endorsed by the speaker? As an exercise in cross-cultural philosophical reflection, we consider some of the leading (...) modern theories of meaning—those of Grice, Quine, and Davidson—in order to see if the Upaniṣadic story receives a natural home in any of them. We conclude that the story is best understood through Grice’s theory of meaning rather than Quine’s or Davidson’s. (shrink)

This paper seeks to lay down the theoretical groundwork for the emergence of holistic cross-cultural philosophical investigations of personal identity ¾ investigations that approach the theoretical, phenomenological, psychological, and practical-ethical dimensions of selfhood as indissociable. My strategy is to discuss three closely connected conceptual distinctions that the Buddhist approach to personal identity urges us to draw, and a lucid understanding of which is essential for the emergence of appropriately comprehensive and thus genuinely cosmopolitan discussions at the cross-road between Western and (...) Buddhist philosophical traditions. The first, primary distinction is that between the “visceral sense of self” and the “substance view of self”. This in turn gives rise to two derivative distinctions, namely between “harbouring VSS” and “believing SVS”, and between “overcoming VSS” and “rejecting SVS”. After discussing these distinctions, I consider and respond to three philosophical objections to features of Buddhist approach to selfhood that are thrown into sharper relief when attention is paid to these three distinctions. I then discuss some of the ways the foregoing may inform research in cross-cultural philosophy of personal identity. This discussion focuses on: the primacy of the first-person stance in matters of personal identity; the relationship between numerical identity and narrative identity; interdisciplinarity in the study of selfhood; and personal identity and egoism.

Names name, but there are no individuals who are named by names. This is the key to an elegant and ideologically parsimonious strategy for analyzing the Buddhist catuṣkoṭi. The strategy is ideologically parsimonious, because it appeals to no analytic resources beyond those of standard predicate logic. The strategy is elegant, because it is, in effect, an application of Bertrand Russell's theory of definite descriptions to Buddhist contexts. The strategy imposes some minor adjustments upon Russell's theory. Attention to familiar catuṣkoṭi from (...) Vacchagotta and Nagarjuna as well as more obscure catuṣkoṭi from Khema, Zhi Yi, and Fa Zang motivates the adjustments. The result is a principled structural distinction between affirmative and negative catuṣkoṭi, as well as analyses for each that compare favorably to more recent efforts from Tillemans, Westerhoff, and Priest.

I discuss two critiques of Dignāga’s epistemology, one from Candrakīrti and another from Jayarāśi. I argue that they are two versions of what I call the core problem: if the content of Dignāga’s epistemology were correct, two fundamental beliefs within this epistemological theory could not be established or known to be true, as Dignāga claims they are. In response to objections found within the classical Indian tradition as well as several plausible contemporary objections, I then argue that the core problem (...) remains a serious issue with which those sympathetic to Dignāga ought to contend.

This is an essay in comparative philosophy and philosophy of religion building on the ontological claims espoused by two major thinkers in the Buddhist and Christian philosophical traditions: Nāgārjuna (c. 150–250) and Hegel (1770–1831). I use Nāgārjuna’s fourfold tetralemma (catuṣkoṭi) and Hegel’s threefold dialectic (Dialektik) to propose a novel understanding of the ontological status of the self in its relation to itself and to its other, the no-self. Thus, I apply the tetralemma to the self, arguing that, to attain ontic (...) completion, the self must itself reflect the tetralemmic form in the totality of its being – nothing – both-being-and-nothing – neither-being-nor-nothing. These in turn correspond to the Hegelian in-itself, for-another, both-in-itself-and-for-another, and neither-in-itself-nor-for-another. (shrink)

This paper evaluates several recent efforts to interpret the work of Nāgārjuna through the lens of modern symbolic logic. An attempt is made to uncover the premises that justify the use of symbolic logic for this purpose. This is accomplished through a discussion of (1) the historical origins of those premises in the Indian and Tibetan traditions, and (2) how such assumptions prejudice our understanding of Nāgā rjuna’s insistence that he has no “proposition” (pratijñā). Finally, the paper sets forth an (...) alternative interpretation that takes into account the literary dimensions of Nāgārjuna’s writing. (shrink)

A number of different kinds of negation and negation of negation are developed in Indian thought, from ancient religious texts to classical philosophy. The paper explores the Mīmāṃsā, Nyāya, Jaina and Buddhist theorizing on the various forms and permutations of negation, denial, nullity, nothing and nothingness, or emptiness. The main thesis argued for is that in the broad Indic tradition, negation cannot be viewed as a mere classical operator turning the true into the false, nor reduced to the mainstream Boolean (...) dichotomy: 1 versus 0. Special attention is given to how contradiction is handled in Jaina and Buddhist logic. (shrink)
