Stephen Hawking had this to say.
“As we shall see, the concept of time has no meaning before the beginning of time.This was first pointed out by St.Augustine. When asked: What did God do before he created the universe? Augustine didn’t reply: He was preparing Hell for people who asked such questions. Instead he said that time was a property of the universe that God created, and that time did not exist before the beginning of the universe.”
Again from Hawking, re: the unifying theory.
“But the idea that God might want to change his mind is an example of the fallacy pointed out by St. Augustine, of Imagining God as existing in time: time is a property only of the universe that God has created. Presumably, he knew what he intended when he set it up!”
Bertrand Russell a renowned athiest had this to say about Augustine. "The gist of the solution he suggests is that time is subjective: time is in the the human mind, which expects, considers, and remenbers. It follows that there can be no time without a created being, and that to speak of of time before creation is meaningless.
I myself do not agree with this theory, in so far as it makes time something mental. But it is clearly a very able theory, deserving to be seriously considered. I should go further, and say that it is a great advance on the subject in Greek philosophy. It contains a better and clearer statement than Kants of the subjective theory of time- a theory which, since Kant, has been widely accepted among philosophers."
Look. If Stephen Hawking and Bertrand Russell, two secularists if ever there were any, can agree that St. Augustine may have been ahead of his time, who am I to disagree.
