The Principle of Sufficient Reason is very seldom, if ever, referred to in the works of whom we might think of as the eminent Asian metaphysicians. In spite of this, the big picture metaphysical views available in the thought of philosophers such as Nāgārjuna, Fazang and Nishida appear to share certain structural features with views more familiar to us from our own tradition; views that explicitly accept or reject the Principle of Sufficient Reason. Nāgārjuna looks to develop a kind of (...) metaphysical infinitism, Fazang an extreme form of coherentism, and Nishida a species of foundationalism. These three positions - infinitism, coherentism and foundationalism - are typically thought to exhaust the spread of possibilities by those working within the Western tradition. -/- In spite of their similarities to positions advanced within our own tradition, the cosmologies of many of the giants of Asian philosophy are characterised by their rather striking conclusions. Amongst such conclusions for Nāgārjuna is that everything is empty; for Fazang that everything is identical to everything else; and for Nishida that everything depends on absolute nothingness. If the Principle of Sufficient Reason is playing a role in the derivation of such striking conclusions, then it looks that there are more options regarding the metaphysical structure of the world available to us than our own tradition typically courts. If, on the other hand, these striking cosmological conclusions are arrived at without any consideration of sufficient reason, then there may well be ways of reasoning about the overarching structure of reality that are powerful but unfamiliar to Western thinking. In this contribution, I explore what, if any, role the PSR might be playing in the thought of Nāgārjuna , Fazang and Nishida, and what we might be able to learn from it. (shrink)

The aim of this paper is to assess the relation between causation and the notion of emptiness described in Buddhist philosophy. While the Madhyamaka school argues that some entity’s being caused implies its being empty, some contemporary authors have argued that there is a ‘Humean’ regularity account of causation that can both be understood as a plausible model of the earlier Buddhist Abhidharma account of causation and also block the Madhyamaka inference from causation to emptiness. After describing the Abhidharma account (...) of causation, the ‘Humean’ regularity account and the Madhyamaka argument from causation to emptiness, we assess some ways in which this argument may be developed, with particular focus on the ‘ladder of causation’ and on the Madhyamaka account of time. The debate about the relation between causation and emptiness, it appears, is a facet of a more comprehensive metaphysical debate between a (moderate) foundationalism and a thoroughgoing anti-foundationalism.

This paper seeks to reconstruct the meaning of existence in the Pāli discourses of the Buddha by considering how the notion is used in the most systematic contexts in which it appears, and how it could be best interpreted. The discourses are concerned with how existence is used to support and consolidate a certain attitude of ownership, appropriation, and entitlement over contents of experience, in virtue of which one can claim that this or that is ‘mine’. The problem with this (...) move is that it seems to require a degree of stability that is at odds with the fundamental uncertainty (anicca) of all conditioned realities. Existence is used to somehow cover up uncertainty, and thus allow for a semblance of genuine ownership and possession, while in fact possession and ownership are just deluded views doomed to be contradicted by the structural uncertainty of actual experience. This reading entails that the early discourses do share with later traditions an anti-realist inspiration, which is worth exploring in its own right. (shrink)

This paper demonstrates a problem with the philosophical question. To do so, it employs a style of reasoning employed by the Buddhist philosopher Nāgārjuna. Often identified as the neither identical nor distinct argument, this style of reasoning is employed by Nāgārjuna in his Mūlamadhyamakakārikā. The paper concludes by noting that the philosophical question, unreflectively pursued, leads to contradictions.

This thesis is the attempt to find a logical model for, and trace the history of, the catuṣkoṭi as it developed in the Indo-Tibetan milieu and spread, via China, to Japan. After an introduction to the history and key-concepts of Buddhist philosophy, I will finish the first chapter with some methodological considerations about the general viability of comparative philosophy. Chapter §2 is devoted to a logical analysis of the catuṣkoṭi. Several attempts to model this fascinating piece of Buddhist philosophy with (...) the tools of classical logic shall be debunked. A paraconsistent alternative will be discussed but eventually dismissed. As a rejoinder, I shall propose a model for the catuṣkoṭi with the help of speech-acts. The remainder of this chapter will look at Chinese and Japanese forms of the catuṣkoṭi which I shall model in a quasi-recursive system. The third and final chapter will look at the Kyoto School's soku-hi dialectics which ties together the different threads of this essay. I will criticise an established, classical model of the soku-hi dialectics and offer an alternative with a second-order paraconsistent semantics. (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)

The recent literature on Nāgārjuna’s catuṣkoṭi centres around Jay Garfield’s and Graham Priest’s interpretation. It is an open discussion to what extent their interpretation is an adequate model of the logic for the catuskoti, and the Mūla-madhyamaka-kārikā. Priest and Garfield try to make sense of the contradictions within the catuskoti by appeal to a series of lattices – orderings of truth-values, supposed to model the path to enlightenment. They use Anderson & Belnaps's framework of First Degree Entailment. Cotnoir has argued (...) that the lattices of Priest and Garfield cannot ground the logic of the catuskoti. The concern is simple: on the one hand, FDE brings with it the failure of classical principles such as modus ponens. On the other hand, we frequently encounter Nāgārjuna using classical principles in other arguments in the MMK. There is a problem of validity. If FDE is Nāgārjuna’s logic of choice, he is facing what is commonly called the classical recapture problem: how to make sense of cases where classical principles like modus pones are valid? One cannot just add principles like modus pones as assumptions, because in the background paraconsistent logic this does not rule out their negations. In this essay, I shall explore and critically evaluate Cotnoir’s proposal. In detail, I shall reveal that his framework suffers collapse of the kotis. Taking Cotnoir’s concerns seriously, I shall suggest a formulation of the catuskoti in classical Boolean Algebra, extended by the notion of an external negation as an illocutionary act. I will focus on purely formal considerations, leaving doctrinal matters to the scholarly discourse – as far as this is possible. (shrink)
