Charlton Heston narrates Kenneth L Schmitz, St Thomas Aquinas (Nashville, TN: Knowledge Products ; Ashland, Or: Blackstone Audiobooks, 2006) audio excerpt, 2 min.
Book Description: In the late 13th century, this quiet reflective Dominican scholar concentrated his work on philosophical concerns that today would be considered to be partly theological. He combined the work of Aristotle with Christian, Jewish, Muslim, and pagan thought to reconcile reason and faith; he believed we can know that God exists, but not what God is like. Thomas's masterpiece, the Summa Theologiae (Summa Theologica), contains over 10,000 objections and replies to fundamental questions about God and the world. It enumerates virtues and vices, and it includes Thomas's famous "five ways" to prove God's existence, which are (1) the unmoved mover, (2) the uncaused cause, (3) the necessary being, (4) the perfect Goodness, and (5) the guiding intelligence. Thomas believed that God is absolutely simple, perfect, good, infinite, omnipresent, changeless, eternal, and unique.
