This book explores the contributions to the philosophy of mind made by the Tibetan Buddhist thinker Phya pa Chos kyi seng ge (1109–1169) in his seminal text, the “Dispeller of the Mind’s Darkness.” This study, which includes a critical edition and English translation of those portions of the “Dispeller” devoted to explicating the nature of mental episodes and their objects, contributes to a deeper understanding of Tibetan intellectual history, while also facilitating a wider appreciation of both Phya pa’s theory of (...) mind and its significance within the global history of philosophy.

The works of the Tibetan logician Phya pa Chos kyi seng ge (1109–1169) make abundant use of a particular type of argument that I term ‘argument by parallels’. Their main characteristic is that the instigator of the argument, addressing a thesis in a domain A, introduces a parallel thesis in an unrelated domain B. And in the ensuing dialogue, each of the instigator’s statements consists in replicating his interlocutor’s previous assertion, mutatis mutandis, in the other domain (A or B). I (...) show that such a dialogue involves two parallel arguments that develop in an intersecting zigzag pattern, and discuss the principles involved in the establishment of the conclusion from the perspective of parity of reasoning and analogical argument. I examine the overall rhetorical strategy directing the use of arguments by parallels and the pedagogical and explanatory functions they can serve. I also evaluate the plausibility of their use in Phya pa Chos kyi seng ge’s works mirroring a contemporary practice of oral debate, and reflect on the status of such arguments in the framework of Indo-Tibetan logic.

This paper examines the modalities and mechanism of text-use pertaining to Indian and Tibetan material in a selection of Tibetan Buddhist epistemological treatises written between the eleventh and the thirteenth century. It pays special attention to a remarkable feature of this corpus: the phenomenon of “repeat,” that is, the unacknowledged integration of earlier material by an author within his own composition. This feature reveals an intellectual continuity in the tradition, and is found even for authors who claim a rupture from (...) their predecessors. Regarding acknowledged text re-use in the form of quotations, I consider which factors condition the identification of the source or the lack thereof, and what role quotations play for the respective authors. In particular, I discuss whether any inference can be drawn, from the presence or absence of quotations, about an author’s knowledge of the corresponding source. (shrink)

This paper presents the main aspects of the views of the Tibetan logician Phya pa Chos kyi seng ge (1109–1169) on argumentation “by consequence” (thal ʼgyur, Skt. prasaṅga) based on his exposition of the topic in the fifth chapter of his Tshad ma yid kyi mun sel and on a parallel excursus in his commentary on Dharmakīrti’s Pramānaviniścaya. It aims at circumscribing primarily the nature and function of consequences (thal ʼgyur/thal ba) for this author—in particular the distinction between “proving consequences” (...) and “refuting consequences”—and the form prescribed for their enunciation in the context of debate. In addition to pointing out differences with the systems adopted by his predecessors, contemporaries and successors, the paper also discusses some of the similarities and differences between Phya pa’s understanding of argumentation by consequence and the notion of reductio ad absurdum in Western logic.

The Tibetan Buddhist logician Phya pa Chos kyi seng ge devoted a large part of his discussion on argumentation to arguments by consequence. Phya pa distinguishes in his analysis arguments by consequence that merely refute the opponent and arguments by consequence that qualify as probative. The latter induce a correct direct proof which corresponds to the reverse form of the argument by consequence. This paper deals with Phya pa’s classification of probative consequences based on the type of the logical reason (...) involved. I first establish the basis of Phya pa’s classification—the typology of logical reasons in inference-for-oneself—with a special attention to logical reasons consisting in the ‘apprehension of something incompatible [with the negandum]’ and among them the specific case of the ‘apprehension of the cause of something incompatible [with the negandum]’. The treatment of the latter is shown to be instrumental in Phya pa’s classification, as well as in explaining the divergences that occur in the models adopted by his successors, such as gTsang nag pa brTson ʾgrus seng ge and mTshur ston gZhon nu seng ge. Turning to Phya pa’s effective application of this typology when he resorts himself to arguments by consequence, I examine Phya pa’s rephrasing, in the form of four arguments by consequence, of the discussion on the relation between the two realities found in the Saṃdhinirmocanasūtra and relate it to a parallel discussion in an earlier Madhyamaka work by rGya dmar ba Byang chub grags. I compare the variant versions of these four arguments in three Madhyamaka works of Phya pa and show that the differences pertaining to the identification of the type of the logical reason result from apparently insignificant variations in the formulation of each of the arguments. In the conclusion, I discuss the potential philosophical or practical interest of such a classification. (shrink)

This paper examines the Buddhist’s answer to one of the most famous (and more intuitive) objections against the semantic theory of “exclusion” ( apoha ), namely, the charge of circularity. If the understanding of X is not reached positively, but X is understood via the exclusion of non-X, the Buddhist nominalist is facing a problem of circularity, for the understanding of X would depend on that of non-X, which, in turn, depends on that of X. I distinguish in this paper (...) two strategies aiming at “breaking the circle”: (i) conceding the precedence of a positive understanding of X, from which a negative understanding (i.e., the understanding of “non-X”) is derived by contrast, and (ii) denying any precedence by proposing a simultaneous understanding of both X and non-X. I consider how these two options are articulated respectively by Dharmakīrti in his Pramāṇavārttika cum Svavṛtti and by one of his Tibetan interpreters, Sa skya Paṇḍita, and examine the requirements for their workability. I suggest that Sa skya Paṇḍita’s motivation to opt for an alternative solution has to do with his criticism of notions shared by his Tibetan predecessors, an outline of which is given in Appendix 1. In Appendix 2, I present the surprising use of the charge of circularity by an early Tibetan logician against his coreligionists. (shrink)

This paper attempts to make sense of Dharmakīrti’s conflicting statements regarding the object of valid cognition ( prameya ) in various parts of his works, considering in particular the claims that (i) there are two kinds of prameyas (particulars and universals), (ii) the particular alone is prameya , and (iii) what is non-existent also qualifies as prameya . It inquires into the relationship between validity ( prāmāṇya ), reliability ( avisaṃvāda ) and causal efficacy ( arthakriyā ) and suggests that (...) the discussion on non-existent prameyas in Pramāṇaviniścaya 3 provides an alternative to an overall “practicalist” reading of Dharmakīrti, practicalist in the sense that pramāṇas are primarily oriented toward human aims and hence bear on objects capable of fulfilling them through their causal capacities. Considering the views of Dharmakīrti’s interpreters, it shows how Dharmottara (8th c.), rejecting such an alternative, strives to reconcile claim (iii) with a practicalist interpretation, while Phya pa Chos kyi seng ge (12th c.) generalizes the application of a criterion of validity superseding an arthakriyā -oriented framework by bringing to the fore the notion of “non-opposition” ( abādhana ) introduced by Dharmakīrti with regard to non-existent prameyas and suprasensorial objects.

This paper examines a passage of the eleventh chapter of the Rigs gter of Sa skya Paṇḍita on the division of arguments by consequence of the form “Because S is P, it follows that it is Q” with respect to the type of relation between P and Q. This passage appears in quite different versions in several available recensions of the Rigs gter, all of which are problematic to some extent. The different interpretations of the commentators can be shown to (...) derive from their reliance on different versions of the text, which they strove to make sense of through two distinct strategies. Following up on the examination of a division of arguments by consequence along the same line in the works of Sa skya Paṇḍita’s Tibetan predecessors, in particular Phya pa Chos kyi seng ge and mTshur ston gZhon nu seng ge :883–938, 2016b), I evaluate the diverging versions of the Rigs gter against a coherent logical scenario founded on Sa skya Paṇḍita’s discussion pertaining to the types of logical reasons in inference in the tenth chapter of his work and comparison with the classification by Phya pa. I offer a hypothesis regarding the genesis of the problematic versions of the passage on the classification of consequences in the Rigs gter based on the comparison with the classification found in mTshur ston’s epistemological work. I propose that the composition of this portion of the Rigs gter might have involved a textual reuse of mTshur ston’s classification, even though mTshur ston and Sa skya Paṇḍita disagree on background issues. This very disagreement imposed changes to the reused text that led to problematic readings. (shrink)
