The absence of theistic belief...

{Defining the word 'atheism'}

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.

Atheism is without God. It does not assert no God. The atheist does not say that there is no God, but he says 'I know not what you mean by God. I am without the idea of God. The word God to me is a sound conveying no clear or distinct affirmation. I do not deny God, because I cannot deny that of which I have no conception, and the conception of which by its affirmer is so imperfect that he is unable to define it for me.

People are invariably surprised to hear me say I am both an atheist and an agnostic, as if this somehow weakens my certainty. I usually reply with a question like, 'Well, are you a Republican or an American?' The two words serve different concepts and are not mutually exclusive. Agnosticism addresses knowledge; atheism addresses belief. The agnostic says, 'I don't have a knowledge that God exists.' The atheist says, 'I don't have a belief that God exists.' You can say both things at the same time. Some agnostics are atheistic and some are theistic.

Beliefs sink in the sea of truth.

An atheist should never be allowed to say "I believe...".
