I'm only guessing, but I think it has more to do with the efficacy of logic as a tool to overcome arguments not grounded in any logic to begin with. I agree with Free Thinker's Darwin reference about gradual illumination.Quote from Ricter:
All this means to me is that logic cannot meet every human need. Is that a big revelation?
Quote from Free Thinker:
"NOR MUST WE OVERLOOK THE PROBABILITY OF THE CONSTANT INCULCATION IN A BELIEF IN GOD ON THE MINDS OF CHILDREN PRODUCING SO STRONG AND PERHAPS AS INHERITED EFFECT ON THEIR BRAINS NOT YET FULLY DEVELOPED, THAT IT WOULD BE AS DIFFICULT FOR THEM TO THROW OFF THEIR BELIEF IN GOD, AS FOR A MONKEY TO THROW OFF ITS INSTINCTIVE FEAR AND HATRED OF A SNAKE."
