An important Indian philosopher and Indologist who introduced many Western thinkers to Indian philosophical thought by demonstrating the common concerns of the two traditions. A brilliant Sanskrit scholar, he was educated, and subsequently taught (1957–1962) at the Sanskrit College in Kolkata (Calcutta). His PhD on Navya Nyāya was obtained at Harvard (1965). After a period as Professor of Sanskrit at Toronto University, he was elected in 1977 to the Spalding Chair of Eastern Religions and Ethics at Oxford University, which he occupied until his early death. His work was wide-ranging, covering not just Nyāya-Vaiśeṣika, but Mīmāṃsā, Buddhist and Jain philosophy, Ethics, and the philosophy of language. He founded and edited the Journal of Indian Philosophy; his many publications include: Navya Nyāya Doctrine of Negation (1968), Epistemology, Logic and Grammar in Indian Philosophical Analysis (1971), Logic, Language and Reality (1985), and The Word and the World: India's Contribution to the Study of Language (1990).
