Dugald Stewart (1753–1828) lectured in astronomy and political economy, held the chair of mathematics at Edinburgh University from 1775 to 1785, then the chair of moral philosophy from 1785 to 1810, and wrote extensively on metaphysics, political economy, ethics, philology, aesthetics, psychology and the history of philosophy and the experimental sciences. He is commonly regarded as the last voice of the Scottish Enlightenment, the articulate disciple of Thomas Reid, father of Scottish common sense philosophy. Recently some historians have begun to rediscover elements of the contribution Stewart made to early nineteenth-century British intellectual culture, and his Collected Works have been republished with a new introduction by Knud Haakonssen.
