A Brahman, founder of the Brahmo-Somaj, born at Burdwân, Lower Bengal; by study of the theology of the West was led to embrace deism, and tried to persuade his countrymen to accept the same faith, by proofs which he advanced to show that it was the doctrine of their own sacred books, in particular the Upanishads; with this view he translated and published a number of texts from them in vindication of his contention, as well as expounded his own conviction in original treatises; in doing so he naturally became an object of attack, and was put on his defence, which he conducted in a succession of writings that remain models of controversial literature; died in Bristol (1772-1833).
