“It is important, likewise, that the habits of thinking in a free country should inspire caution in those entrusted with its administration, to confine themselves within their respective constitutional spheres, avoiding in the exercise of the powers of one department to encroach upon another. The spirit of encroachment tends to consolidate the powers of all the departments in one, and thus to create, whatever the form of government, a real despotism…The necessity of reciprocal checks in the exercise of political power, by dividing and distributing it into different depositaries, and constituting each the guardian of the public weal against invasions by the others, has been evinced by experiments ancient and modern; some of them in our country and under our own eyes. To preserve them must be as necessary as to institute them…let there be no change by usurpation; for though this, in one instance, may be the instrument of good, it is the customary weapon by which free governments are destroyed. The precedent must always greatly overbalance in permanent evil any partial or transient benefit, which the use can at any time yield.” — George Washington, Farewell Address, 1796.
“Whenever I hear any one arguing for slavery I feel a strong impulse to see it tried on him personally.” — Abraham Lincoln, “Speech to One Hundred Fortieth Indiana Regiment” (March 17, 1865)
“Few men have virtue to withstand the highest bidder.” — George Washington
“It is said an Eastern monarch once charged his wise men to invent him a sentence to be ever in view, and which should be true and appropriate in all times and situations. They presented him the words: ‘And this, too, shall pass away.’ How much it expresses! How chastening in the hour of pride! How consoling in the depths of affliction!” — Abraham Lincoln, “Address Before the Wisconsin State Agricultural Society, Milwaukee, Wisconsin” (September 30, 1859)
