"Detect quacks"? Yes do, for Heaven's sake; but know withal the men that are to be trusted! Till we know that, what is all our knowledge; how shall we even so much as "detect"? For the vulpine sharpness, which considers itself to be knowledge, and "detects" in that fashion, is far mistaken. Dupes indeed are many: but, of all dupes, there is none so fatally situated as he who lives in undue terror of being duped."

“On the whole, we will repeat that this Religion of Mahomet's is a kind of Christianity; has a genuine element of what is spiritually highest looking through it, not to be hidden by all its imperfections. The Scandinavian God Wish, the god of all rude men, — this has been enlarged into a Heaven by Mahomet; but a Heaven symbolical of sacred Duty, and to be earned by faith and well-doing, by valiant action, and a divine patience which is still more valiant. It is Scandinavian Paganism, and a truly celestial element superadded to that. Call it not false; look not at the falsehood of it, look at the truth of it. For these twelve centuries, it has been the religion and life-guidance of the fifth part of the whole kindred of Mankind. Above all things, it has been a religion heartily believed. These Arabs believe their religion, and try to live by it! No Christians, since the early ages, or only perhaps the English Puritans in modern times, have ever stood by their Faith as the Moslem do by theirs, — believing it wholly, fronting Time with it, and Eternity with it.”

“suppose Odin to have been the inventor of Letters, as well as "magic," among that people! It is the greatest invention man has ever made! this of marking down the unseen thought that is in him by written characters. It is a kind of second speech, almost as miraculous as the first.”

“Every candid eye, I think, will read the Koran far otherwise than so. It is the confused ferment of a great rude human soul; rude, untutored, that cannot even read; but fervent, earnest, struggling vehemently to utter itself in words. With a kind of breathless intensity he strives to utter himself; the thoughts crowd on him pell-mell: for very multitude of things to say, he can get nothing said. The meaning that is in him shapes itself into no form of composition, is stated in no sequence, method, or coherence;—they are not shaped at all, these thoughts of his; flung out unshaped, as they struggle and tumble there, in their chaotic inarticulate state.”

“Such parliamentary bagpipes I myself have heard play tunes, much to the satisfaction of the people.”

“Wonder is the basis of worship.”

“I here, on the very threshold, protest against it in reference to Paganism, and to all other isms by which man has ever for a length of time striven to walk in this world. They have all had a truth in them, or men would not have taken them up. Quackery and dupery do abound; in religions, above all in the more advanced decaying stages of religions, they have fearfully abounded: but quackery was never the originating influence in such things; it was not the health and life of such things, but their disease, the sure precursor of their being about to die! Let us never forget this.”
