A Short Biographical Dictionary of English Literature/Occam or Ockham, William
Occam or Ockham, William (1270?-1349?). -- Schoolman, b. at Ockham, Surrey, studied at Oxf. and Paris, and became a Franciscan. As a schoolman he was a Nominalist and received the title of the Invincible Doctor. He attacked the abuses of the Church, and was imprisoned at Avignon, but escaped and spent the latter part of his life at Munich, maintaining to the last his controversies with the Church, and with the Realists. He was a man of solid understanding and sense, and a masterly logician. His writings, which are of course all in Latin, deal with the Aristotelean philosophy, theology, and specially under the latter with the errors of Pope John XXII., who was his bête-noir.
