Thomas Aquinas, O.P. ( /əˈkwaɪnəs/ ə-KWY-nəs; 1225 – 7 March 1274), also Thomas of Aquin or Aquino, was an Italian Dominican priest of the Roman Catholic Church, and an immensely influential philosopher and theologian in the tradition of scholasticism, known as Doctor Angelicus ([the] Angelic Doctor), Doctor Communis, or Doctor Universalis. "Aquinas" is not a surname, but is a Latin demonym for a resident of Aquino, his place of birth. 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 as a reaction against, or as an agreement with, his ideas, particularly in the areas of ethics, natural law, metaphysics, and political theory.

Thomas is held in the Catholic Church to be the model teacher for those studying for the priesthood. The works for which he is best-known are the Summa Theologica and the Summa Contra Gentiles. As one of the 33 Doctors of the Church, he is considered the Church's greatest theologian and philosopher. Pope Benedict XV declared: "This (Dominican) Order ... acquired new luster when the Church declared the teaching of Thomas to be her own and that Doctor, honored with the special praises of the Pontiffs, the master and patron of Catholic schools."

Sir Anthony John Patrick Kenny FBA (born 16 March 1931 in Liverpool) is an English philosopher whose interests lie in the philosophy of mind, ancient and scholastic philosophy, the philosophy of Wittgenstein and the philosophy of religion. With Peter Geach, he has made a significant contribution to Analytical Thomism, a movement whose aim is to present the thought of St Thomas Aquinas in the style of modern philosophy by clearing away the trappings and obscurities of traditional Thomism. He is one of the executors of Wittgenstein's literary estate. He is a former President of the British Academy and the Royal Institute of Philosophy.

Kenny initially trained as a Roman Catholic priest at the Venerable English College, Rome, where he received the degree of S.T.L. He was ordained in 1955 and served as Curate in Liverpool 1959-63. Having received his D.Phil. from the University of Oxford (St Benet's Hall) in 1961, he also worked as an Assistant Lecturer in the University of Liverpool (1961–63). However, he questioned the validity of Catholic doctrine and is now an agnostic. He was returned to the lay state in 1963, but according to Canon law his priestly ordination remains valid. He was never dispensed from the obligation of clerical celibacy and was therefore excommunicated on his marriage to Nancy Gayley in 1965.
