That's what I meant.
"God," could be described through various interpretations, I think the philosopher's concept of God is a bit different to the Judeo-Christian's interpretations of Him, as I don't believe they regarded "God" in the metaphysical or "gnostic" sense, but rather as Aristotle sees it, the image in our head that we are trying to replicate through our actions, ergo morality.
But that brings us back to the origin of morality. I think morality isn't "made up," in the basic sense but a trait that is psychologically innate to group cooperation. In other words, morality appears as a set of unspoken rules that men follow in order to work together.
But is it Nature or Nurture?
