In the first chapter of his Prasannapadā, Candrakīrti famously defended Buddhapālita against Bhāviveka’s criticism that he had failed to formulate Nāgārjuna’s critique of causality in terms of probative arguments, but rather left the arguments in the form of reductios. This debate is well known to be the starting point of the “Prāsaṅgika-Madhyamaka” interpretation in Tibet.  Indeed, Tsongkhapa (1357-1419) has said that “an autonomous probative argument is not suitable to generate the view of thusness in an opponent” in the context of explaining Candrakīrti’s Prāsaṅgika (dgongs pa rab gsal, 226). In his critique of Tsongkhapa’s synthesis of Prāsaṅgika-Madhyamaka and pramāṇa, the fifteenth-century Sakya scholar, Daktsang (stag tsang), accused Tsongkhapa of “eighteen great contradictions,” including a contradiction that “the presence of inference contradicts the absence of probative arguments.” That is, Daktsang argued that a robust notion of inference – that is, inference qua pramāṇa – is antithetical to the logic behind Candrakīrti’s denial of probative arguments in this context. This paper discusses some of the issues driving this debate and shows how this debate sheds light on the place of epistemology in an anti-realist interpretation of Madhyamaka.

An account of fairness and probability is given using Game Theoretical Semantics to schematize fairness as a “draw” result of a logical game. The two concepts of probability — objective frequency vs. subjective belief — are then described as differences in game strategy. Lastly the logical machinery is used to potentially bridge the gap between the two, giving perspective on the problem of induction.

I’ve argued that the Indian Buddhist tradition, broadly construed, has tended to endorse a unique view of freedom and responsibility, a view I’ve called Buddhist Perspectivalism. According to this view, we should always regard ourselves as genuinely free and responsible agents, because we have good reason to do so, while we should never regard others in this way, because we have equally good reason to see them as neither free nor responsible. In this talk, I clarify Buddhist Perspectivalism as a theory of moral responsibility and defend it against some concerns that scholars like Christopher Gowans and Charles Goodman have raised.

One well-known objection to the principle of maximum entropy is the so-called Judy Benjamin problem, first introduced by van Fraassen (1981). The problem turns on the apparently puzzling fact that, on the basis of information relating an event’s conditional probability, the maximum entropy distribution will almost always assign to the event conditionalized on a probability strictly less than that assigned to it by the uniform distribution. In this paper, I present an analysis of the Judy Benjamin problem that can help to make sense of this seemingly odd feature of maximum entropy inference. My analysis is based on the claim that, in applying the principle of maximum entropy, Judy Benjamin is not acting out of a concern to maximize uncertainty in the face of new evidence, but is rather exercising a certain brand of epistemic charity towards her informant. This charity takes the form of an assumption on the part of Judy Benjamin that her informant’s evidential report leaves out no relevant information. I will explain how this single assumption suffices to rationalize Judy Benjamin’s behavior. I will then explain how such a re-conceptualization of the motives underlying Judy Benjamin’s appeal to the principle of maximum entropy can further our understanding of the relationship between this principle and the principle of insufficient reason. I will conclude with a discussion of the foundational significance for probability theory of ergodic theorems (e.g., de Finetti’s theorem) describing the asymptotic behavior of measure preserving transformation groups. In particular, I will explain how these results, which serve as the basis of maximum entropy inference, can provide a unified conceptual framework in which to justify both a priori and a posteriori probabilistic reasoning.

A subjective probability function is broadminded to the extent that it assigns positive probabilities to conjectures that can be possibly true. Assigning to such a conjecture the value 0 amounts to a priori ruling out the possibility of confirming the conjecture to any extent by the growing evidence. A positive value leaves, in principle, the possibility of learning from the evidence. In general, broadmindedness is not an absolute notion, but a graded one, and there is a price for it: the more broadminded the probability, the more complicated it is, because it has to assign non-zero values to more complicated conjectures. The framework which is suggested in the old Gaifman-Snir paper is suitable for phrasing this claim in a precise way and proving it. The technique by which this claim is established is to assume a definable probability function, and to state within the same language a conjecture that can be possibly true, whose probability is 0.

The complexity of the conjecture depends on the complexity of the probability, i.e., the complexity of the formulas that are used in defining it. In the Gaifman-Snir paper we used the arithmetical hierarchy as a measure of complexity. It is possible however to establish similar results with respect to a more “down to earth” measures, defined in terms of the time that it takes to calculate the probabilities, with given precisions.

A claim of this form, for a rather simple setup, was first proven by Hilary Putnam in his paper ““Degree of Confirmation” and inductive logic”, which was published in the 1963 Schilpp volume dedicated to Carnap. The proof uses in a probabilistic context, a diagonalization technique, of the kind used in set theory and in computer science. In the talk I shall present Putnam’s argument and show how diagonalization can be applied in considerably richer setups.

The second part of the talk is rather speculative. I shall point out the possibility that there might be epistemic limitations to what human science can achieve, which are imposed by certain pragmatic factors ‒ such as the criterion of repeatable experiments. All of which would recommend a skeptic attitude.

The Pratyabhijñā Śaiva tradition, as first systematized by Utpaladeva (10th century) and elaborated by Abhinavagupta (10th-11th century), follows a number of other classical Indian philosophical traditions in 1) fully acknowledging that Buddhist Vijñānavādins claim to account for the diversity manifest in the conventional world through an appeal to beginningless karmic imprints; and 2) utterly rejecting that this solution avoids circularity. To sum up the Śaiva critique: a Vijñānavādin cannot avoid the question of what causes the diversity of experiences in the conventional world by appealing to beginningless causal processes because these processes themselves require the existence of some kind of real stuff that has the capacity to manifest in diverse forms. These Śaivas hone their argument in relation to a Dharmakīrtian view of ultimate consciousness as utterly beyond causal relations—a view that Dharmakīrti (7th century) uses to brush aside any questions about the real relationship between conventional and ultimate reality as incoherent. These Śaivas argue that the question of how the variegation of a specific moment of awareness arises if no part of this variegation­—including the variegation of the causes that produce it—is inherent to what is ultimately real is philosophically salient. Moreover, this question cannot be addressed simply by an appeal to beginningless ignorance. While an appeal to beginningless karmic imprints is perfectly sufficient to account for the differences between various karmic streams within the conventional world, it is not sufficient to account for the mere fact that there is differentiated stuff capable of entering into causal relations. The Pratyabhijñā Śaivas offer a complex and distinctive solution to this problem: while they affirm that ultimate reality is beginningless in the sense that it is beyond time, they also claim that time itself has a “beginning” in the expression of the nondual differentiation inherent to the ultimate itself. They further link the expression of time with the creation of the subject/object pairs that define conventional worlds—and use Dharmakīrti’s own apoha (exclusion) theory of concept formation to explain how this happens.

The circa 9th century CE poet-saint Saraha enjoys a close association with spontaneity in both his reported actions and recorded works. This association leads him to be popularly read and remembered as a freewheeling antinomian sacred figure opposed to institutions, rituals, and even social norms. His appears to be a call to joyful chaos. But many of his verses invite readers towards a different kind of chaos, towards mental/perceptual chaos as the path towards correct conventional perception.

What does it mean to correctly perceive an object? Many Buddhist sources describe how perception functions, and theorize the differences between correct and incorrect perception. A related important distinction is made between conventional and ultimate truth in the discussion of the reality of phenomena even when correctly perceived. But this arguably epistemic distinction may also be understood as the difference between an ordinary person’s correct perception and a Buddha’s perception. I am not here exploring ultimate truth. I am interested in conventional truth, in what makes it true. Broadly, correct conventional perception is associated with the product of a rational mind processing sense perceptions fed to it by functioning sense organs, and conventional truth then is the experience of that reality. Correct conventional perception can be contrasted with incorrect conventional perception, which would be perception based on an irrational or deluded mind, or an experience based on damaged or non-functioning sense organs.

Saraha, however, sings a different tune. His work tells us that the very process of identifying and recognizing objects – what most of us would associate with the basic skills necessary to get around in the world – is itself deluded, its objects adventitious. He calls this kind of perception drenpa (dran pa; usually translated as mindfulness, memory, or recollection). In other words, he claims that our very perception of objects – no matter how carefully or clearly experienced – is evidence of our being deluded. In contrast, correct conventional perception is the undoing of that object-making, what he refers to as drenmé (dran med). Drenmé is an uncommon term the contexts of the two truths and meditation. Usually denoting a swoon or a coma, here it refers to a reversal or undoing of drenpa. What does it mean – if it means anything – to describe our perception of objects itself as evidence of our delusion? Can perception as object-making ever produce truth?

At the core of Kantian liberalism is a conception of the independent autonomous subject. On the other hand, the most central and distinguishing feature of Buddhist philosophy is the doctrine of no-self. It thus seems that Buddhists should reject Kantian liberalism. My larger project develops the connections between Buddhist perfectionism, liberalism, and principles of justice. In this paper, I focus on Buddhist and Kantian conceptions of self-constitution, but my ultimate concern is the significance of the doctrine of no-self to theories of justice.

Buddhists need some conception of a minimal self to account for the karmic-continuity of persons and also to provide an adequate account of the subjectivity of experience. I argue that we should reject the (Abhidharma) reductionist view of the self as a mere fiction that is reducible to its simpler and more basic parts. As is often noted, the Buddhist reductionist approach is similar to Derek Parfit’s view. Parfit also argues that there is no deep metaphysical self and that relations of personal identity are reducible to relations of psychological connectedness and causal continuity in a series of experiences. Christine Korsgaard has responded to Parfit’s reductionist view by developing a non-metaphysical account of Kantian agency and self-constitution. I argue that the Buddhist doctrine of no-self is consistent with a more minimal, non-substantial, emergent, view of the self. This approach, which is more fully developed by Evan Thomson, Matthew MacKenzie, Georges Dreyfus, and others, is surprisingly similar to Korsgaard’s practical conception of the self. As a result, the non-reductionist Buddhist approach is also not vulnerable to Korsgaard’s objection to reductionist views. In addition, I argue that the process of self-constitution is embedded in a recursive nexus of dependent origination, and reject Korsgaard’s conception of the independent autonomous subject, which she refers to as “over and above” its ends. In short, a Buddhist can accept Korsgaard’s basic account of self-constitution but nonetheless reject the Kantian idea of the independent autonomous subject. For Buddhists, the Kantian autonomous subject is instead part of the “primal confusion” that projects a reified subject-other division on experience. This confusion is the source of existential suffering, anxiety and stress, which characterizes too much of the human condition. The goal is to transcend the Kantian subject and internalize the pervasive interdependence of persons. Instead of the autonomous self, Buddhism embraces a perfectionist ideal, of a non-egocentric reorientation and re-constitution of the self.

Buddhists thus have reason to reject Kantian liberalism, if it is based on the autonomy and independence of persons. In his shift to Political Liberalism, John Rawls recasts the conception of the person, as “a self-originating source of valid claims,” and emphasizes that this conception is restricted to the political domain. It is part of a narrow conception of the “moral powers” of a free and equal citizen; it is not a metaphysical conception or comprehensive ideal. I conclude by exploring the contrast between Buddhist Perfectionism and Political Liberalism.
