“No sooner was the Baltic open to our merchants, than corn was bought up there for importation into England; at the same time the continent was glutted with English goods, which, because the supply greatly exceeded the demand, were sold at less than their prime cost, and upon which the foreign governments soon laid new duties...to prevent the ruin of their own manufactures. This might have been a salutary lesson, if nations were ever rendered wise by experience; it might have taught us that, however willing one part of this nation might be to see the other ruined by the free admission of foreign grain, foreign governments would never consent to have their fabrics destroyed by the unrestricted introduction of British goods. It is a sound maxim in politics, whatever it may be in morals, that charity begins at home.”

Introduction, as translated by H. B. Nisbet (1975)
Variant translation: What experience and history teach is this — that people and governments never have learned anything from history, or acted on principles deduced from it.
Pragmatical (didactic) reflections, though in their nature decidedly abstract, are truly and indefeasibly of the Present, and quicken the annals of the dead Past with the life of to-day. Whether, indeed, such reflections are truly interesting and enlivening, depends on the writer's own spirit. Moral reflections must here be specially noticed, the moral teaching expected from history; which latter has not unfrequently been treated with a direct view to the former. It may be allowed that examples of virtue elevate the soul, and are applicable in the moral instruction of children for impressing excellence upon their minds. But the destinies of peoples and states, their interests, relations, and the complicated tissue of their affairs, present quite another field. Rulers, Statesmen, Nations, are wont to be emphatically commended to the teaching which experience offers in history. But what experience and history teach is this, that peoples and governments never have learned anything from history, or acted on principles deduced from it. Each period is involved in such peculiar circumstances, exhibits a condition of things so strictly idiosyncratic, that its conduct must be regulated by considerations connected with itself, and itself alone. Amid the pressure of great events, a general principle gives no help. It is useless to revert to similar circumstances in the Past. The pallid shades of memory struggle in vain with the life and freedom of the Present.

Arguing against the right of the US Government to force his people to leave their lands (1876)
Context: In the treaty councils the commissioners have claimed that our country had been sold to the Government. Suppose a white man should come to me and say, "Joseph, I like your horses, and I want to buy them." I say to him, "No, my horses suit me, I will not sell them." Then he goes to my neighbor, and says to him: "Joseph has some good horses. I want to buy them, but he refuses to sell." My neighbor answers, "Pay me the money, and I will sell you Joseph's horses." The white man returns to me and says, "Joseph, I have bought your horses, and you must let me have them." If we sold our lands to the Government, this is the way they were bought.
