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.
