It is natural that people should differ most, and most violently, about the unknowable . . . There is all the room in the world for divergence of opinion about something that, so far as we can realistically perceive, does not exist.

When confronted by a ‘believer’ it is easy for me to contrast the views of the skeptic with those of the rationalist. I simply reach into my pocket and pull out my change.

Holding a quarter aloft, I say, ‘This is a most remarkable coin, for it is heavier than all the sins of humanity committed since the beginning of the human race.’

I then hold up a nickel and say, ‘This coin is even more amazing, as it is brighter and shinier than the flames that proceeded from the Burning Bush discovered on Mt. Sinai by Moses.’

Then I raise a penny and state, ‘This portrait of President Lincoln is more realistic and true-to-life than any portrait of Satan ever painted.’

And finally, I hold out a bright, shiny dime and say, ‘And this dime is the most amazing of all because it is heavier and contains more precious metals than all the gold bricks in the streets of Heaven.’

I end with ‘Give to Caesar what is his, and hold the rest of it dear—for it is all you see and touch—and the Christian god can take care of all his things, for they amount to less than this 41 cents I hold here in my hand.

Atheism is a conclusion reached by the most reasonable methods and one which is not asserted dogmatically but is explained in its every feature by the light of reason. The atheist does not boast of knowing in a vainglorious, empty sense. He understands by knowledge the most reasonable and clear and sound position one can take on the basis of all the evidence at hand. This evidence convinces him that theism is not true, and his logical position, then, is that of atheism.

We repeat that the atheist is one who denies the assumptions of theism. he asserts, in other words, that he doesn't believe in a God because he has no good reason for believing in a God. That's atheism -- and that's good sense.

We advocate the atheistic philosophy because it is the only clear, consistent position which seems possible to us. As atheists, we simply deny the assumptions of theism; we declare that the God idea, in all its features, is unreasonable and unprovable; we add, more vitally, that the God idea is an interference with the interests of human happiness and progress. We oppose religion not merely as a set of theological ideas; but we must also oppose religion as a political, social and moral influence detrimental to the welfare of humanity.

The lack of perception, doesn't equal non-existence.
