I am simply an agnostic. I haven't yet had time or opportunity to explore the universe, and I don't know what I might run on to in some nook or corner.

With all their faults, trade-unions have done more for humanity than any other organization of men that ever existed.

In spite of all the yearnings of men, no one can produce a single fact or reason to support the belief in God and in personal immortality.

I have always felt that doubt was the beginning of wisdom, and the fear of God was the end of wisdom.
