The debates between various Buddhist and Hindu philosophical systems about the existence, definition and nature of self, occupy a central place in the history of Indian philosophy and religion. These debates concern various issues: what 'self' means, whether the self can be said to exist at all, arguments that can substantiate any position on this question, how the ordinary reality of individual persons can be explained, and the consequences of each position. At a time when comparable issues are at the forefront of contemporary Western philosophy, in both analytic and continental traditions (as well as in their interaction), these classical and medieval Indian debates widen and globalise such discussions. This book brings to a wider audience the sophisticated range of positions held by various systems of thought in classical India.
