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 IngersollAs long as every question is answered by the word "God," scientific inquiry is simply impossible.
Robert Green IngersollThink of the egotism of a man who believes that an infinite being wants his praise!
Robert Green IngersollWe can be as honest as we are ignorant. If we are, when asked what is beyond the horizon of the known, we must say that we do not know.
