Galileo, Gassendi, and other eminent men. Returning to England he remained in the Earl's service, and devoted himself to his studies on philosophy and politics. The commotions of the times, however, disturbed him; and his Royalist principles, expounded in his treatise, De Corpore Politico, led to his again, in 1641, leaving England and going to Paris, where he remained until 1652. While there, he entered into controversy on mathematical subjects with Descartes, pub. some of his principal works, including Leviathan, and received, in 1647, the appointment of mathematical tutor to the Prince of Wales, afterwards Charles II., who was then in that city. The views expressed in his works, however, brought him into such unpopularity that the Prince found it expedient to break the connection, and H. returned to England. In 1653 he resumed his relations with the Devonshire family, living, however, in London in habits of intimacy with Selden, Cowley, and Dr. Harvey. On the Restoration the King conferred upon him a pension of £100, but like most of the Royal benefactions of the day, it was but irregularly paid. His later years were spent in the family of his patron, chiefly at Chatsworth, where he continued his literary activity until his death, which occurred in 1679, in his 91st year. H. was one of the most prominent Englishmen of his day, and has continued to influence philosophical thought more or less ever since, generally, however, by evoking opposition. His fundamental proposition is that all human action is ultimately based upon selfishness (more or less enlightened), allowing no place to the moral or social sentiments. Similarly in his political writings man is viewed as a purely selfish being who must be held in restraint by the strong hand of authority. His chief philosophical works are De Corpore Politico, already mentioned, pub. in 1640; Philosophical Rudiments concerning Government and Society, originally in Latin, translated into English in 1650; Leviathan, or the Matter, Form, and Power of a Commonwealth, Ecclesiastical and Civil (1651); Treatise on Human Nature (1650); and Letters upon Liberty and Necessity (1654). Generally speaking, all his works led him into controversy, one of his principal opponents being Clarendon. The Letters upon Liberty and Necessity, which is one of the ablest of them, and indeed one of the ablest ever written on the subject, brought him into collision with Bramhall, Bishop of Londonderry, whom he completely overthrew. He was not, however, so successful in his mathematical controversies, one of the chief of which was on the Quadrature of the Circle. Here his antagonist was the famous mathematician Wallis, who was able easily to demonstrate his errors. In 1672, when 84, H. wrote his autobiography in Latin verse, and in the same year translated 4 books of the Odyssey, which were so well received that he completed the remaining books, and also translated the whole of the Iliad. Though accurate as literal renderings of the sense, these works fail largely to convey the beauties of the original, notwithstanding which three ed. were issued within 10 years, and they long retained their popularity. His last work was Behemoth, a history of the Civil War, completed just before his death, which occurred at Hardwick Hall, one of the seats of the Devonshire family. Although a clear and bold thinker, and a keen controversialist, he was characterised by a certain constitutional timidity believed to
