These latter few I call the true atheists. Probably the strongest argument for God is a functional one. That is, we need to believe in God, even if he is not there, because such a belief creates social order and generally makes us happy. In other words, the only excuse for God is that He doesn't exist. Religion is not the opiate of the people.
Opium suggests something soporific, numbing, dulling.
Too often religion has been an aphrodisiac for horror, a Benzedrine for bestiality. At its best it has lifted spirits and raised spires. At its worst it has turned entire civilizations into cemeteries. I rest my case. The greatest act of faith is when a man decides that he is not God.
