Colebrooke’s last contributions to Oriental learning, which appeared in the “Transactions” of the newly-founded Royal Asiatic Society, consist chiefly in his masterly treatises on Hindu philosophy. In 1823 he read his paper on the Sânkhya system; in 1824 his paper on the Nyâya and Vaiśeshika systems; in 1826 his papers on the Mîmânsâ; and, in 1827, his two papers on Indian Sectaries and on the Vedânta. These papers, too, still retain their value, unimpaired by later researches. They are dry, and to those not acquainted with the subject they may fail to give a living picture of the philosophical struggles of the Indian mind. But the statements which they contain can, with very few exceptions, still be quoted as authoritative, while those who have worked their way through the same materials which he used for the compilation of his essays, feel most struck by the conciseness with which he was able to give the results of his extensive reading in this, the most abstruse domain of Sanskrit literature. The publication of these papers on the schools of Indian metaphysics, which anticipated with entire fidelity the materialism and idealism of Greece and of modern thought, enabled Victor Cousin to introduce a brilliant survey of the philosophy of India into his Lectures on the History of Philosophy, first delivered, we think, in 1828. Cousin knew and thought of Colebrooke exclusively as a metaphysician. He probably cared nothing for his other labors. But as a metaphysician he placed him in the first rank, and never spoke of him without an expression of veneration, very unusual on the eloquent but somewhat imperious lips of the French philosopher. The last years of Colebrooke’s life were full of suffering, both bodily and mental. He died, after a lingering illness, on March 10, 1837.
