Although memory is pivotal to consciousness and without it no perceptual judgment or thinking is possible, Nyāya epistemology does not accept memory as a knowledge source. Prof Matilal elucidates and defends Udayana’s justification for calling into question the knowledgehood or even truth of any recollection. Deepening Matilal’s argument, this paper first shows why, if a remembering reproduces exactly the original experience from which it borrows its truth-claim, then there is a mismatch between the time of experience and the time of (...) recall and the remembering ends up being false. To correct that error, if we change the tense in the content of recollection, the added past-ness goes beyond the original experience and violates the purely reproductive nature of memory. The paper ends by responding to this Nyāya position using arguments from Dvaita Vedānta and Jaina epistemology where remembering can be veridical and memory is accepted as an important knowledge source. The additional element of past-ness cannot be derived from sense perception. It has to be a spontaneous contribution of the inner sense. (shrink)

Western scholars have written on the theory of Buddhist argumentation. They have also analyzed examples of arguments found in philosophical and polemical writing. However, little has been written to date about what might have transpired when Buddhists and their opponents met in face-to-face debates in classical India. Drawing on Chinese and Tibetan historical and biographical writings about famous Indian debates, this essay analyzes the structure and conventions of these accounts as a literary form. While it is difficult to assess the (...) historicity of particular narratives, an analysis of this literature as a whole gives us clues about what might have occured when Indian scholars faced their adversaries in live debates. These sources provide us with a picture of the etiquette, rules of engagement, and strategies that may have been used in such encounters. They also suggest what constituted defeat in ancient Indian verbal contests, and they point to some of the real-political and material benefits of victory. The essay ends by reflecting on the function of these narratives vis-à-vis Tibetan Buddhist scholastic identity. (shrink)

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)

Previous studies have claimed that the term ‘all-inclusive pervasion’ ( sarvopasaṃhāravyāpti ) appeared for the first time in the Hetubindu , and that it was Dharmakīrti who created this theory. This article attempts to modify this view and to show that the prototype of this theory can already be found in Dignāga’s system of logic. Dignāga states in the third chapter of the Pramāṇasamuccayavṛtti that the co-existence of a logical reason with what is to be proved is understood by means (...) of two types of exemplification that sum up external items ( bāhyārthopasaṃhṛta ). Furthermore, with respect to where the pervasion is indicated, he states in the second chapter of the same work that the non-deviation of a logical mark from what is to be proved is indicated elsewhere ( anyatra ). He also implies that anyatra means in the substratum in general ( ādhārasāmānya ) and that the subject is implicitly included in other substrata, i.e., in the substratum in general. Building upon Dignāga’s awareness of the issue, the conflict between the universality of pervasion and the particularity of actual inference, Dharmakīrti reinforced Dignāga’s system of logic by demonstrating that a property to be proved as the universal is not particularised by the subject by the use of the idea of ‘the exclusion of nonconnection’ ( ayogavyavaccheda ) and by adopting the concept of ‘all’ in place of ‘external items’.

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.

This paper is a critical review of Jonardan Ganeri’s Philosophy in Classical India.

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)

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.

While Kripke's original paper on the theory of truth used a three-valued logic, we believe a four-valued version is more natural. Its use allows for possible inconsistencies in information about the world, yet contains Kripke's development within it. Moreover, using a four-valued logic makes it possible to work with complete lattices rather than complete semi-lattices, and thus the mathematics is somewhat simplified. But more strikingly, the four-valued version has a wide, natural generalization to the family of interlaced bilattices. Thus, with (...) little more work, the theory is extended to a broad class of settings. Indeed, a result like Theorem 6.2 would not even be possible to state without the interlaced bilattice machinery. We hope the notion of interlaced bilattice will make apparent further such connections. (shrink)

Emptiness ( śūnyatā ) is one of the most important topics in Buddhist thought and also is one of the most perplexing. Buddhists in Tibet have developed a sophisticated tradition of philosophical discourse on emptiness and ineffability. This paper discusses the meaning(s) of emptiness within three prominent traditions in Tibet: the Geluk ( dge lugs ), Jonang ( jo nang ), and Nyingma ( rnying ma ). I give a concise presentation of each tradition’s interpretation of emptiness and show how (...) each interpretation represents a distinctive aspect of its meaning. Given that Buddhist traditions (1) accept an extra-linguistic reality and (2) maintain a strong tradition of suspicion of language with the belief that language both constructs and distorts reality, this paper responds to an issue that is not so much whether or not an inexpressible reality can be expressed, but rather how it is best articulated.
