"I like the scientific spirit—the holding off, the being sure but not too sure, the willingness to surrender ideas when the evidence is against them: this is ultimately fine—it always keeps the way beyond open—always gives life, thought, affection, the whole man, a chance to try over again after a mistake—after a wrong guess."

“We Americans have yet to really learn our own antecedents, and sort them, to unify them. They will be found ampler than has been supposed, and in widely different sources. Thus far, impress'd by New England writers and schoolmasters, we tacitly abandon ourselves to the notion that our United States has been fashion'd from the British Islands only, and essentially form a second England only — which is a very great mistake.”

“I sound my barbaric yawp over the roofs of the world.”

“Looking over my scraps, I find I wrote the following during 1864. The happening to our America, abroad as well as at home, these years, is indeed most strange. The democratic republic has paid her to-day the terrible and resplendent compliment of the united wish of all the nations of the world that her union should be broken, her future cut off, and that she should be compell'd to descend to the level of kingdoms and empires ordinarily great. There is certainly not one government in Europe but is now watching the war in this country, with the ardent prayer that the United States may be effectually split, crippled, and dismember'd by it. There is not one but would help toward that dismemberment, if it dared. Are we indignant? alarm'd? Do we feel jeopardized? No; help'd, braced, concentrated, rather. We are all too prone to wander from ourselves, to affect Europe, and watch her frowns and smiles. We need this hot lesson of general hatred, and henceforth must never forget it. Never again will we trust the moral sense nor abstract friendliness of a single government of the old world.”

“I say the real and permanent grandeur of these States must be their religion.”
