Theology is not what we know about God, but what we do not know about Nature.

Few nations have been so poor as to have but one god. Gods were made so easily, and the raw material cost so little, that generally the god market was fairly glutted and heaven crammed with these phantoms.

Temptations are as thick as the leaves of the forest, and no one can be out of the reach of temptation unless he is dead. The great thing is to make people intelligent enough and strong enough, not to keep away from temptation, but to resist it.

I believe that labor is a blessing. It never was and never will be a curse. It is a blessed thing to labor for . . . the ones you love. It is a blessed thing to have an object in life - something to do - something to call into play your best thoughts, to develop your faculties and to make you a man.

The only thing that makes life endurable in this world is human love, and yet, according to Christianity, that is the very thing that we are not to have in the other world. We are to be so taken up with Jesus and angels, that we shall care nothing about our brothers and sisters that have been damned. We shall be so carried away with the music of the harp that we shall not even hear the wail of father and mother. Such a religion is a disgrace to human nature.

Where is the soul? . . . I refuse to believe anything of that kind without proof. The idea that, as soon as a man's breath leaves his body, the soul flops out like a chicken's head and flies off into space to find a lodgment where there [are] harps and haloes. Too much for me.

The Catholics have a Pope. Protestants laugh at them, and yet the Pope is capable of intellectual advancement. In addition to this, the Pope is mortal, and the church cannot be afflicted with the same idiot forever. The Protestants have a book for their Pope. The book cannot advance. Year after year, and century after century, the book remains as ignorant as ever.
