MORGAN, THOMAS (d. 1743), English deist, of Welsh extraction, became an independent minister, but soon after 1720 lost his position owing to the growing unorthodoxy of his views. He took up medicine and became a freethinker, though he describes himself as a Christian deist. He was an energetic controversialist. Among his works are Philosophical Principles of Medicine (1725); Collection of Tracts (1726), essays dealing with the Trinitarian controversy; The Moral Philosopher (1737), a dialogue between a Christian Jew, Theophanus, and a Christian deist, Philalethes. He died on the 14th of January 1742/3.
