Professor Kreeft, “Are you an expert on angels?
No. I’m not an expert on anything. There are no experts on angels, except angels, and I’m no angel. (27) In every area of life the secret of originality is to stop trying to be original and just tell the truth as you see it. Most of what I know about angels I learned from Saint Thomas Aquinas. Not all my answers are directly from him, but the principles from which I deduce my answers usually are. (P. 27) No, it isn’t. Angelology is a science, though not an empirical science. It uses an essentially scientific method: gathering data and formulating theories to explain the data. The theories are controlled by the data. Of course it’s not laboratory data. Different sciences have different data. History, mathematics, and textual criticism are all sciences, but none of them have laboratory data either. (28)
Can you prove the reality of the supernatural?
Even if I can’t, you also can’t prove its nonexistence. Naturalism cannot be proved. How could the fish in a little fishbowl prove that there is no world outside the fishbowl? How could an unborn baby prove there is no life outside the womb? (p. 29) … If there is a God, why not angels? If there is an infinite spirit, why can’t there be finite spirits? Why swallow an orange but choke on a kumquat? (3)
