There never was in the world two opinions alike, no more than two hair — Opinion

"Stiff in opinion, always in the wrong."

"The deep slumber of a decided opinion."

"Matters of fact, as Mr. Budgell somewhere observes, are very stubborn things."

"See, one can have an opinion about remote events, about a natural object, about nature, about scholarly works, and about another human being, and so on about much else, and when one expresses this opinion the wise person can decide whether it is correct or incorrect. No one, however, troubles the opinion-holder with a consideration of the other side of truth, whether one actually does have the opinion, whether it is just something one is reciting. Yet this other side is just as important, because not only is that person mad who talks senselessly, but the person is fully as mad who states a correct opinion if it has absolutely no significance for him. The one shows the other the confidence, the acknowledgment, of assuming that he means what he says. Alas, yet it is so easy, so very easy, to acquire a true opinion, and yet it is so difficult, so very difficult, to have an opinion and to have it in truth."

"There is the grand truth about Nathaniel Hawthorne. He says NO! in thunder; but the Devil himself cannot make him say yes. For all men who say yes, lie; and all men who say no,—why, they are in the happy condition of judicious, unincumbered travellers in Europe; they cross the frontiers into Eternity with nothing but a carpet-bag,—that is to say, the Ego. Whereas those yes-gentry, they travel with heaps of baggage, and, damn them! they will never get through the Custom House."

"The rule is perfect: in all matters of opinion our adversaries are insane."
