The man who does not do his own thinking is a slave, and is a traitor to himself and to his fellow-men.

A crime against god is a demonstrated impossibility.

Ignorance worships mystery; reason explains it; the one grovels, the other soars.

It has always seemed absurd to suppose that a god would choose for his companions, during all eternity, the dear souls whose highest and only ambition is to obey.

Intellect, without heart, is infinitely cruel. . . .

The agnostic does not simply say, "l do not know." He goes another step, and he says, with great emphasis, that you do not know. He insists that you are trading on the ignorance of others, and on the fear of others. He is not satisfied with saying that you do not know, -- he demonstrates that you do not know, and he drives you from the field of fact -- he drives you from the realm of reason -- he drives you from the light, into the darkness of conjecture -- into the world of dreams and shadows, and he compels you to say, at last, that your faith has no foundation in fact.
