(1753-1828) Philosopher, son of Matthew S., Professor of Mathematics at Edinburgh, was born in the College buildings, and at the age of 19 began to assist his father in his classes, receiving the appointment of regular assistant two years later. In 1785 he became Professor of Moral Philosophy, and rendered the chair illustrious by his learning and eloquence, his pupils including Lords Palmerston, Russell, and Lansdowne. Stewart was, however, rather a brilliant expositor than an original thinker, and in the main followed Reid (q.v.). His works include Philosophy of the Human Mind, in three volumes, puborn respectively in 1792, 1813, and 1827, Outlines of Moral Philosophy (1793), Philosophical Essays (1810), Dissertation on the Progress of Metaphysical and Ethical Philosophy (1815, part II. 1821), and View of the Active and Moral Powers of Man. He also wrote memoirs of Robertson the historian, Adam Smith, and Reid. The Whig party, which he had always supported, on their accession to power, created for him the office of Gazette-writer for Scotland, in recognition of his services to philosophy. His later years were passed in retirement at Kinneil House on the Forth. His works were edited by Sir William Hamilton.
