If one believes in a god, one is a Theist. If one does not believe in a god, then one is an A-theist — he is without that belief. The distinction between atheism and theism is entirely, exclusively, that of whether one has or has not a belief in God.

All my life I have made it a rule never to permit a religious man or woman take for granted that his or her religious beliefs deserved more consideration than non-religious beliefs or anti-religious ones.

We cannot start with God and deduce the universe from his existence we must start with the world as we know it, and deduce God from the world.

Religion is very enlightening - to those who don't understand it.
