The Oxford Handbook of Indian Philosophy tells the story of philosophy in India through a series of exceptional individual acts of philosophical virtuosity. It brings together forty leading international scholars to record the diverse figures, movements, and approaches that constitute philosophy in the geographical region of the Indian subcontinent, a region sometimes nowadays designated South Asia. The volume aims to be ecumenical, drawing from different locales, languages, and literary cultures, inclusive of dissenters, heretics and sceptics, of philosophical ideas in thinkers not themselves primarily philosophers, and reflecting India's north-western borders with the Persianate and Arabic worlds, its north-eastern boundaries with Tibet, Nepal, Ladakh and China, as well as the southern and eastern shores that afford maritime links with the lands of Theravda Buddhism. Indian Philosophy has been written in many languages, including Pali, Prakrit, Sanskrit, Malayalam, Urdu, Gujarati, Tamil, Telugu, Bengali, Marathi, Persian, Kannada, Punjabi, Hindi, Tibetan, Arabic and Assamese. From the time of the British colonial occupation, it has also been written in English. It spans philosophy of law, logic, politics, environment and society, but is most strongly associated with wide-ranging discussions in the philosophy of mind and language, epistemology and metaphysics (how we know and what is there to be known), ethics, metaethics and aesthetics, and metaphilosophy. The reach of Indian ideas has been vast, both historically and geographically, and it has been and continues to be a major influence in world philosophy. In the breadth as well as the depth of its philosophical investigation, in the sheer bulk of surviving texts and in the diffusion of its ideas, the philosophical heritage of India easily stands comparison with that of China, Greece, the Latin west, or the Islamic world.

The tradition of Samkhya is one of the oldest and most influential in the intellectual history of India. The fundamental notions of Samkhya namely prakrti, purusa, buddhi, ahamkara, manas and the three gunas provided the conceptual framework in which much of Indian philosophizing occurred, and the classical formulations of Yoga and Vedanta together with many traditions of Buddhist philosophy and meditation developed vis-a-vis the intellectual perspective of the Samkhya. Similarly on a general cultural level the influence of Samkhya was profound and important over many centuries in such areas as law, medicine, ancient science and mathematics, logic, mythology, cosmology and ritual. This study traces the history of the Samkhya not only in the Indian intellectual tradition, but also in the traditions of historical criticism. The book also offers a new interpretation of the philosophical significance of the Samkhya, with special reference to the classical interpretation of the interaction of prakrti and purusa. In this edition author has also included a Chart of the Twenty-five Basic Principles of the Samkhya, a Glossary of Samkhya Terminology, an additional Appendix which surveys recent scholarly work in the area of Samkhya together with a discussion of Samkhya in the Purana-s and a revised Bibliography.
