While living in India for sixteen years, James Robert Ballantyne (1813–64) taught oriental languages to Indian pupils and became fascinated by Hindu philosophy, seeking to harmonise it with the Western tradition. He produced grammars of Hindi, Sanskrit and Persian, translations of Indian linguistics, and a science primer in English and Sanskrit (also reissued in the Cambridge Library Collection). Intended for the Tyro missionary and published in 1859, this work offers a summary of Hinduism (covering the Nyaya, Sankhya and Vedanta schools) and argues for the truth of Christianity, while acknowledging certain shared ideas. It contains a facing Sanskrit translation (with redactions of parts considered to be of no importance to 'those whom the missionary has to teach'). A valuable primary source for scholars of orientalism, this work helps to illuminate the religious dimensions of British imperialism.
