Epistemology – the study of the nature and scope of knowledge – has been an integral topic in Indian and Tibetan Buddhist scholastic communities for the past 1500 years. This article provides an overview of the Buddhist epistemological tradition, emphasizing the central role that the concept of pramana plays in Indian theories of knowledge. After elucidating the two pramanas accepted by the Buddhist epistemological tradition, the article concludes by discussing the relationship between Buddhist epistemology and Buddhist soteriology.

The title of the present paper might arouse some curiosity among the minds of the readers. The very first question that arises in this respect is whether India produced any logic in the real sense of the term as has been used in the West. This paper is centered only on the three systems of Indian philosophy namely Nyāya, Buddhism and Jainism. We have been talking of Indian philosophy, Indian religion, Indian culture and Indian spirituality, but not that which are of more fundamental concepts for any branch of knowledge whether it is social sciences or humanities. No aspect of human life and the universe has been left unexamined by Indian philosophers, and this leads to a totality of vision in both philosophical and psychological fields. In this paper we will discuss the main thinkers, sources and main concepts related to different Indian philosophies mentioned above.

This paper discusses some paradoxical propositions in Chinese tradition, especially the School of Names. It not only explains what Chinese philosophers mean by these propositions and why there are such paradoxes in Chinese philosophy, but also makes an attempt to formulate these paradoxical propositions in the language of symbolic logic. Meanwhile, the paper makes a comparison between Chinese views about contradiction and Aristotle?s law ot non?contradiction and explores the relation between them. It comes to the conclusion that once the difference between Chinese concept of contraries and Aristotle?s is made clear, inconsistency between Chinese paradoxial propositions and Aristotle?s. law of non-contradiction disappears.

Łukasiewicz distinguishes three formulations of the principle of contradiction in Aristotle’s works: ontological, logical, and psychological. The first two formulations are equivalent though not synonymous, but neither of them is equivalent to the psychological one, which expresses not a principle but only an empirical law. Furthermore, the principle of contradiction is neither a simple and ultimate law nor is it necessary for conducting an inference, because the syllogism is independent of it. The further explanation of this concept leads Łukasiewicz to formulate the idea of a non-Aristotelian logic, that is, a logic operating without the principle of contradiction. If the principle of contradiction shall be valid, it must be proved. A proof can be supplied only on the basis of a definition of object, as something that cannot have and not have the same property at the same time. However, this definition does not hold for all objects, i.e., for contradictory objects. In virtue of its ontological character the Aristotelian principle of contradiction is then different from that of symbolic logic.

Reconsidering Classical Indian Thoughts neither claims, nor attempts to be a definitive study of all the characteristics as concept(s) of classical Indian thoughts. It is a modest attempt of the editor to familiarise the common, but philosophy reader with the fundamental conceptions of ancient Indian culture. I hope, by studying this book the reader will understand the relevance of Indian classical thoughts.

Here we have collected 20 papers both in English and Hindi languages written on Indian epistemology, metaphysics, logic, ethics and social philosophy. To study the nature of philosophy in India and its implementation in all spheres of human life is one of the most important objectives of our Centre. In this regard we have published two online books entitled Philosophy, Education and Indian Value System and Positive Philosophy for Contemporary Indian Society, respectively.

Papineau has suggested that the Principle of Non-Contradiction is a logical law that ?verificationists? are not entitled to claim as a prioritrue. The Principle, like that of Excluded Middle, is not sufficiently grounded in the ?miserly? epistemology of verificationism to be proven in ?verificationist logic?. We examine who might be challenged by this claim: who are the ?verificationists?? We defend our candidates against Papineau's criticisms and other attacks, but this leaves the verificationist open to a different criticism.
