Dr Sir Sarvepalli Radhakrishnan[1] pronunciation (help·info), OM, FBA (Telugu: సర్వేపల్లి రాధాకృష్ణ; 5 September 1888, Tiruttani, Tamil Nadu – 17 April 1975) was an Indian philosopher and statesman. He was the first Vice President of India (1952–1962) and subsequently the second President of India (1962–1967).

One of India's most influential scholars of comparative religion and philosophy, Radhakrishnan is thought of as having built a bridge between the East and the West by showing that the philosophical systems of each tradition are comprehensible within the terms of the other. He wrote authoritative exegeses of India's religious and philosophical literature for the English speaking world. His academic appointments included the King George V Chair of Mental and Moral Science at the University of Calcutta (1921–1931) and Spalding Professor of Eastern Religion and Ethics at Oxford University (1936–1952).

Among the many honours he received were a knighthood (1931), the Bharat Ratna (1954) and the Order of Merit in 1963. His birthday is celebrated in India as Teachers' Day on 5 September.

This classic work is a general introduction to Indian philosophy that covers the Vedic and Epic periods, including expositions on the hymns of the Rig Veda, the Upanisads, Jainism, Buddhism and the theism of the Bhagvadgita. Long acknowledged as a classic, this pioneering survey of Indian thought charts a fascinating course through an intricate history. From the Rig Veda to Ramanuja, Radhakrishnan traces the development of Indian philosophy as a single tradition of thought through the ages. The author showcases ancient philosophical texts and relates them to contemporary issues of philosophy and religion. This second edition with a new Introduction by eminent philosopher J.N. Mohanty, highlights the continuing relevance of the work and the philosophic tradition it represents.
