Thomas Aquinas, also Thomas of Aquin or Aquino, was an Italian Dominican priest, and an immensely influential philosopher and theologian in the tradition of scholasticism, within which he is also known as the "Dumb Ox", "Angelic Doctor", "Doctor Communis", and "Doctor Universalis".
"Aquinas" is the demonym of Aquino: Thomas came from one of the noblest families of the Kingdom of Naples, with the title of "counts of Aquino". He was the foremost classical proponent of natural theology, and the father of Thomism. His influence on Western thought is considerable, and much of modern philosophy was conceived in development or refutation of his ideas, particularly in the areas of ethics, natural law, metaphysics, and political theory.
