I am, indeed, an absolute materialist so far as actual belief goes; with not a shred of credence in any form of supernaturalism—religion, spiritualism, transcendentalism, metempsychosis, or immortality.
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.
At the very time that philosophers of the most enterprising benevolence were founding in Greece those institutions which have rendered it the wonder and luminary of the world, am I required to believe that the weak and wicked king of an obscure and barbarous nation, a murderer, a traitor and a tyrant, was the man after God's own heart?
The Romans called the Christians atheists. Why? Well, the Christians had a god of sorts, but it wasn't a real god. They didn't believe in the divinity of apotheosized emperors or Olympian gods. They had a peculiar, different kind of god. So it was very easy to call people who believed in a different kind of god atheists. And that general sense that an atheist is anybody who doesn't believe exactly as I do prevails in our own time.
However modest one may be in one's demand for intellectual cleanliness, one cannot help feeling, when coming into contact with the New Testament, a kind of inexpressible discomfiture: for the unchecked impudence with which the least qualified want to raise their voice on the greatest problems, and even claim to be judges of such things, surpasses all measure. The shameless levity with which the most intractable problems (life, world, God, purpose of life) are spoken of, as if they were not problems at all but simply things that these little bigots knew!
All I say is that I think it is damned unlikely that anything like a central cosmic will, a spirit world, or an eternal survival of personality exist. They are the most preposterous and unjustified of all the guesses which can be made about the universe, and I am not enough of a hair-splitter to pretend that I don't regard them as arrant and negligible moonshine. In theory I am an agnostic, but pending the appearance of radical evidence I must be classed, practically and provisionally, as an atheist.
Religious apologists complain bitterly that atheists and secularists are aggressive and hostile in their criticism of them. I always say: look, when you guys were in charge, you didn't argue with us, you just burnt us at the stake. Now what we're doing is, we're presenting you with some arguments and some challenging questions, and you complain.
He who lives as children live - who does not struggle for his bread and does not believe that his actions possess any ultimate significance - remains childlike.
Progress is Providence without God. That is, it is a theory that everything has always perpetually gone right by accident. It is a sort of atheistic optimism, based on an everlasting coincidence far more miraculous than a miracle.
I cannot conceive of a God who rewards and punishes his creatures, or has a will of the type of which we are conscious in ourselves. An individual who should survive his physical death is also beyond my comprehension, nor do I wish it otherwise; such notions are for the fears or absurd egoism of feeble souls.
As is well known, the priests are the most evil enemies—but why? Because they are the most impotent. It is because of their impotence that in them hatred grows to monstrous and uncanny proportions, to the most spiritual and poisonous kind of hatred. The truly great haters in world history have always been priests; likewise the most ingenious haters: other kinds of spirit hardly come into consideration when compared with the spirit of priestly vengefulness.
I'm not an atheist. I don't think I can call myself a pantheist. The problem involved is too vast for our limited minds. We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written those books.
