Posted on: April 2nd, 2007 Heidegger (and Lewis) on the “Religious Uses of Atheism”
"To this God (of rationalism or utlitarianism) man can neither pray nor offer sacrifice. Before the causa sui man can not fall on his knees in reverence, nor can he hymn or worship such a God. For this reason atheistic thought that denies the God of philosophy, the God as causa sui is perhaps closer to the divine God." — Heidegger, Identity and Difference.
This reminds me of the passage in Mere Christianity where CS Lewis says that it is better for a boy who does not really believe in God to stop going to church than to continue to attend. When he does this he is actually closer to God than he is when he continues his charade.
