Buddhist philosophy in India in the early sixth century C. E. took an important tum away from the traditional methods of explaining and systematizing the teachings in Siitra literature that were attributed to the Buddha. The new direction in which several Indian Buddhist philosophers began to move was that of following reasoning to its natural conclusions, regardless whether the conclusions conflicted with traditional teachings. The central figure in this new movement was DiIinaga, a native of South India who found his (...) way to the centre of Buddhist education at Nalanda, studied the treatises that were learned by the Buddhist intellectuals of his day, and eventually wrote works of his own that formed the core of a distinctly new school of Buddhist thought. Inasmuch as virtually every Indian philosopher after the sixth century had either to reject Dirinaga's methods or build upon the foundations provided by his investigations into logic, epistemology and language, his influence on the evolution of Indian philosophy was considerable, and indeed some familiarity with Dirinaga's arguments and conclusions is indispensable for anyone who wishes to understand the historical development of Indian thought. Moreover, since the approach to Buddhism that grew out of Dirinaga's meditations on language and the limits of knowledge dominated the minds of many of the scholars who took Buddhism to Tibet, some familiarity with Dirinaga is also essential to those who wish to understand the intellectual infrastructure of Tibetan Buddhist philosophy and practice.

The Tattvapaplavasimha is a philosophical text unique of its kind it is the only text of the Carvaka Lokayata school which has survived and the only Sanskrit work in which full-fledged scepticism is propounded. Notwithstanding that it has been hitherto almost completely ignored. The present book consists of an introduction detailed analysis edition translation with extensive notes of the first half of the text. In the introduction Jayarasi`s affiliation to the Lokayata school is reassessed and his place in the historical (...) development of Indian Philosophy evaluated. New evidence for the dating of Jayarasi is examined and a new dating is suggested. (shrink)

: Claus Oetke, in his "Ancient Indian Logic as a Theory of Non-monotonic Reasoning," presents a sweeping new interpretation of the early history of Indian logic. His main proposal is that Indian logic up until Dharmakirti was nonmonotonic in character-similar to some of the newer logics that have been explored in the field of Artificial Intelligence, such as default logic, which abandon deductive validity as a requirement for formally acceptable arguments; Dharmakirti, he suggests, was the first to consider that a (...) good argument should be one for which it is not possible for the property identified as the "reason" (hetu) to occur without the property to be proved (sadhya)-a requirement akin to deductive validity. Oetke's approach is challenged here, arguing that from the very beginning in India something like monotonic, that is, deductively valid, reasoning was the ideal or norm, but that the conception of that ideal was continually refined, in that the criteria for determining when it is realized were progressively sharpened.

The last work of the eminent philosopher Bimal Krishna Matilal, this book traces the origins of logical theory in India.

The word 'philosophy' as well as the conjuring expression 'Indian philosophy' has meant different things to different people-endeavours and activities, old and new, grave and frivolous, edifying and banal, esoteric and exoteric. In this book, the author has chosen deliberately a very dominant trend of the classical (Sanskrit) philosophical literature as his subject of study. The age of the material used here demands both philological scholarship and philosophical amplification. Classical pramanasastras usually deal with the theory of knowledge, the nature of (...) inference and language, and the related questions of ontology and semantics. Several important concepts and theories have been singled out for critical analysis and clarification in modern terms so that the results may be intelligible to modern students of both Sanskrit and philosophy. It is hoped that such an attempt will kindle the enthusiasm of young scholars in the field and inspire them to proceed in this comparatively new area of research and explore further and more interesting possibilities.

The articles in this volume are all landmarks in the evolution of modern studies in Indian logic. The book traces the development of modern studies in Indian logic from their beginnings right up to the latest work.

Despite its importance, the work is rather secondary in the sense that it relies, for the most part, on the Buddhist logical legacy. The first extant commentary is the Nyayavatara-vivrti of Siddharsigani.
