He wrote in Latin a Book of Commentaries on Asiatic Poetry, in English several works on the Mohammedan and Civil Law, with a translation of the Greek Orations of Isæus. As a lawyer, a judge, a student of natural history, his ardor of study was equally apparent. He presented to the Royal Society in London a large collection of valuable Oriental manuscripts, and left a long list of studies in Sanskrit to be pursued by those who should come after him. His generous nature showed itself in his opposition to slavery and the slave-trade, and his open sympathy with the American Revolution. His correspondence was large, including such names as those of Benjamin Franklin, Sir Joseph Banks, Lord Monboddo, Gibbon, Warren Hastings, Dr. Price, Edmund Burke, and Dr. Parr. Such a man ought to be remembered, especially by all who take an interest in the studies to which he has opened the way, for he was one who had a right to speak of himself, as he has spoken in these lines:-- "Before thy mystic altar, heavenly truth, I kneel in manhood, as I knelt in youth. Thus let me kneel, till this dull form decay, And life's last shade be brightened by thy ray, Then shall my soul, now lost in clouds below, Soar without bound, without consuming glow." Since the days of Sir William Jones immense progress has been made in the study of Sanskrit literature, especially within the last thirty or forty years, from the time when the Schlegels led the way in this department. Now, professors of Sanskrit are to be found in all the great European universities, and in this country we have at least one Sanskrit scholar of the very highest order, Professor William D. Whitney, of Yale. The system of Brahmanism, which a short time since could only be known to Western readers by means of the writings of Colebrooke, Wilkins, Wilson, and a few others, has now been made accessible by the works of Lassen, Max Müller, Burnouf, Muir, Pictet, Bopp, Weber, Windischmann, Vivien de Saint-Martin, and a multitude of eminent writers in France, England, and Germany.[31] § 2. Difficulty of this Study. The Complexity of the System. The Hindoos have no History. Their Ultra-Spiritualism. But, notwithstanding these many helps, Brahmanism remains a difficult study. Its source is not in a man, but in a caste. It is not the religion of a Confucius, a Zoroaster, a Mohammed, but the religion of the Brahmans. We call it Brahmanism, and it can be traced to no individual as its founder or restorer. There is no personality about it.[32] It is a vast world of ideas, but wanting the unity which is given by the life of a man, its embodiment and representative. But what a system? How large, how difficult to understand! So vast, so complicated, so full of contradictions, so various and changeable, that its very immensity is our refuge! We say, It is impossible to do justice to such a system; therefore do not demand it of us.
