Renowned philosopher J. N. Mohanty examines the range of Indian philosophy from the Sutra period through the 17th century Navya Nyaya. Instead of concentrating on the different systems, he focuses on the major concepts and problems dealt with in Indian philosophy. The book includes discussions of Indian ethics and social philosophy, as well as of Indian law and aesthetics.

This book is a defence of a form of realism which stands closest to that upheld by the Nyãya-Vaid'sesika school in classical India. The author presents the Nyãya view and critically examines it against that of its traditional opponent, the Buddhist version of phenomenalism and idealism. His reconstruction of Nyãya arguments meets not only traditional Buddhist objections but also those of modern sense-data representationalists.
