Thomas Aquinas (Italian: Tommaso d'Aquino, lit. 'Thomas of Aquino'; 1225 – 7 March 1274) was an Italian Dominican friar, philosopher, Catholic priest, and Doctor of the Church. An immensely influential philosopher, theologian, and jurist in the tradition of scholasticism, he is also known within the latter as the Doctor Angelicus and the Doctor Communis. The name Aquinas identifies his ancestral origins in the county of Aquino in present-day Lazio, Italy. He was the foremost classical proponent of natural theology and the father of Thomism; of which he argued that reason is found in God. His influence on Western thought is considerable, and much of modern philosophy developed or opposed his ideas, particularly in the areas of ethics, natural law, metaphysics, and political theory. Unlike many currents in the Church of the time, Thomas embraced several ideas put forward by Aristotle—whom he called "the Philosopher"—and attempted to synthesize Aristotelian philosophy with the principles of Christianity. His best-known works are the Disputed Questions on Truth (1256–1259), the Summa contra Gentiles (1259–1265), and the unfinished but massively influential Summa Theologica aka Summa Theologiae (1265–1274).
