But to show you my heart fully, my friends: if there were gods, how could I bear to be not a god! Therefore, there are no gods.

Since only what is material is perceptible, knowable, nothing is known of the existence of God.

It seems to me absurd to doubt that a man may be an ardent Theist and an evolutionist. ... I have never been an atheist in the sense of denying the existence of a God.

I do not believe in the God of the theologians; but that there is a Supreme Intelligence I do not doubt.

When the solution is simple, God is answering.

It is hard to sneak a look at God's cards. But that he would choose to play dice with the world ... is something I cannot believe for a single moment.
