I have read enough. I did not see in any of his writings where he attributed moral absolutes to God. Where is that? He spoke of a mystical inner voice which is the seat of morality, and he spoke of Justice with a capital J, and of the "right will," but I have never seen anything attributed to Socrates (he didn't have any writings of his own - they are from Plato and Xenophon). I do not hold the greek philosophers in the high esteem that you do, but I believe Plato was the best since he understood that there are ideals and truths independent of man. The problem is for all the greeks is as F. Schaeffer explained: You cannot logical start with finite man and reason your way to the infinite or univeral; you must start with the infinite-personal and reason your way down.
Close of the Apology. BTW the independence you speak of in Plato is more true for Socrates.
