In the spirit of the best way to learn something is to teach it, I led a Church History section on Thomas Aquinas' Summa yesterday. We discussed Part One, Questions 1 & 2, which deal with the nature and extent of Christian doctrine, and the existence of God.
In these first two questions, Thomas is trying to prove that Christian theology meets Aristotle's three criteria for a science: 1. Its first principles are secured; 2. It proceeds by deductive syllogisms, and 3. It's comprehensive.
Now one might object that Theology is not a science because not everyone believes; thus its first principles aren't secured. Thomas replies that a science's first principles can be secured in themselves, like mathematics, or they can be secured in a higher science, like music, which is a science because it's applied math. So then, Christian theology is a science in the way that music is. It's first principles aren't secured in itself, but in Divine Revelation, which is even more secure than any human science.
One student wasn't impressed by this argument because it appeared to her that Thomas is begging the question. Thomas hasn't yet demonstrated any reasonable proof that God exists. That comes in Question 2. Does he have a right to appeal to revelation so early in his argument?
Does anybody have a reply to this? I didn't.
P.S. Of all the proofs for God's existence, I like this one, which trades on the distinction between necessary and contingent creatures. Everything that exists in nature, says Thomas, didn't have to exist. We're all contingent creatures. Now, given an infinite amount of time, all possibilities for the coming into existence or not coming into existence of contingent creatures would be exhausted, including the possibility that none of us came into existence. Now if that had ever happened, nothing would exist even to this day because a contingent creature can't create himself. Obviously that didn't happen. So there has to be a necessary being to call the rest of us contingent beings into being. "And by this everyone takes it to mean God."
Itn't that great?
