There's no bigger atheist than me. Well, I take that back. I'm a cancer screening away from going agnostic and a biopsy away from full-fledged Christian.
Many statements about God are confidently made by theologians on grounds that today at least sound specious. Thomas Aquinas claimed to prove that God cannot make another God, or commit suicide, or make a man without a soul, or even make a triangle whose interior angles do not equal 180 degrees. But Bolyai and Lobachevsky were able to accomplish this last feat (on a curved surface) in the nineteenth century, and they were not even approximately gods.
Good churches are not built by bad men; at least, there must be probity and enthusiasm somewhere in the society. These minsters were neither built nor filled by atheists.
Since our inner experiences consist of reproductions, and combinations of sensory impressions, the concept of a soul without a body seem to me to be empty and devoid of meaning.
It is the most ambitious and driven among us who are the most sorely in need of having our reckless hopes dampened through immersive dousings in the darkness which religions have explored. This is a particular priority for secular Americans, perhaps the most anxious and disappointed people on earth, for their nation infuses them with the most extreme hopes about what they may be able to achieve in their working lives and relationships.
Existentialism isn't so atheistic that it wears itself out showing that God doesn't exist. Rather, it declares that even if God did exist, that would change nothing.
God knows, I'm not the thing I should be, Nor am I even the thing I could be, But twenty times I rather would be An atheist clean, Than under gospel colours hid be Just for a screen.
