"As in an icicle the agnostic abides alone. The vital principle is taken out of all endeavor for improving himself or bettering hisfellows. All hope in the grand possibilities of life are blasted."

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.

— Robert Green Ingersoll
