 one of Professor Jaffa's favorite quotations. It's in both Aristotle and Thomas Aquinas. This alone is denied even to God to make what has been not to have been. And that states something about nature, right? One of the first things you have to teach people in education, the thing I learned more than any other from Professor Jaffa and his students and my fellow students of his, was that you have to approach things as if they are real and find out what they're like.
