I can see how it might be possible for a man to look down upon the earth and be an atheist, but I cannot conceive how he could look up into the heavens and say there is no God.
- Abraham Lincoln

The Hebrews have done more to civilize men than any other nation. If I were an atheist, and believed blind eternal fate, I should still believe that fate had ordained the Jews to be the most essential instrument for civilizing the nations.
- John Adams

The modern atheist is always angered when he hears anything said about God and religion. He would be incapable of such a resentment if God were only a myth.
- Fulton John Sheen (1895-1979)

The opposite of the religious fanatic is not the fanatical atheist but the gentle cynic who cares not whether there is a god or not.
- Eric Hoffer

Now that I am a Christian I do not have moods in which the whole thing looks very improbable: but when I was an atheist I had moods in which Christianity looked terribly probable.
- C. S. Lewis

Atheism is a crutch for those who can’t bear the reality of God.
- Tom Stoppard

If there were no God, there would be no Atheists.
- G. K. Chesterton

Among the repulsions of atheism for me has been its drastic uninterestingness as an intellectual position.
- John Updike

[The] belief that a groundless ethic can promote an increase in
tolerance and peace is simply false. Historical examples indicate
that atheism has contributed (directly) to the most horrific
totalitarian regimes the world has ever seen. If God is dead, then
one can certainly conclude that humanity is dead as well. In the
absence of God, there is no one to have mercy on our souls.
- Thomas Raucherstein, “Nietzsche and Rorty on Morality and the Death of God” (2000)

If atheism spread, it would become a religion as intolerable as the ancient ones.
- Gustave le Bon 1841-1931, Aphorisms du temps présent
