“Governments will rise, and governments will fall, and man will do evil to man, and all we can do is turn our hearts to good.”

On the United States Declaration of Independence, and the United States Constitution at the U.S. Bicentennial celebrations, Independence Hall, Philadelphia, Pennsylvania (4 July 1976)
1970s
Context: The Declaration was not a protest against government but against the excesses of government. It prescribed the proper role of government to secure the rights of individuals and to effect their safety and their happiness. In modern society, no individual can do this all alone, so government is not necessarily evil but a necessary good.
The framers of the Constitution feared a central government that was too strong, as many Americans rightly do today. The framers of the Constitution, after their experience under the Articles, feared a central government that was too weak, as many Americans rightly do today. They spent days studying all of the contemporary governments of Europe and concluded with Dr. Franklin that all contained the seeds of their own destruction. So the framers built something new, drawing upon their English traditions, on the Roman Republic, on the uniquely American institution of the town meeting.

Context: In all cases, therefore, we will agree with the judicious Mrs. Glass: 'First catch your hare!' First get your man; all is got: he can learn to do all things, from making boots, to decreeing judgments, governing communities; and will do them like a man.

Context: A man contains all that is needful to his government within himself. He is made a law unto himself. All real good or evil that can befal [sic] him must be from himself. He only can do himself any good or any harm. Nothing can be given to him or can taken from him but always there is a compensation.. There is a correspondence between the human soul and everything that exists in the world; more properly, everything that is known to man. Instead of studying things without the principles of them, all may be penetrated unto with him. Every act puts the agent in a new position. The purpose of life seems to be to acquaint a man with himself. He is not to live the future as described to him but to live the real future to the real present. The highest revelation is that God is in every man.

1850s, Speech at Peoria, Illinois (1854)
Context: "Fools rush in where angels fear to tread." At the hazard of being thought one of the fools of this quotation, I meet that argument — I rush in — I take that bull by the horns. I trust I understand and truly estimate the right of self-government. My faith in the proposition that each man should do precisely as he pleases with all which is exclusively his own lies at the foundation of the sense of justice there is in me. I extend the principle to communities of men as well as to individuals. I so extend it because it is politically wise, as well as naturally just: politically wise in saving us from broils about matters which do not concern us. Here, or at Washington, I would not trouble myself with the oyster laws of Virginia, or the cranberry laws of Indiana. The doctrine of self-government is right, — absolutely and eternally right, — but it has no just application as here attempted. Or perhaps I should rather say that whether it has such application depends upon whether a negro is not or is a man. If he is not a man, in that case he who is a man may as a matter of self-government do just what he pleases with him.
But if the negro is a man, is it not to that extent a total destruction of self-government to say that he too shall not govern himself. When the white man governs himself, that is self-government; but when he governs himself and also governs another man, that is more than self-government — that is despotism. If the negro is a man, why then my ancient faith teaches me that "all men are created equal," and that there can be no moral right in connection with one man's making a slave of another.

Political Disquisitions (1774)
Context: That government only can be pronounced consistent with the design of all government, which allows to the governed the liberty of doing what, consistently with the general good, they may desire to do, and which only forbids their doing the contrary. Liberty does not exclude restraint; it only excludes unreasonable restraint. To determine precisely how far personal liberty is compatible with the general good, and of the propriety of social conduct in all cases, is a matter of great extent, and demands the united wisdom of a whole people. And the consent of the whole people, as far as it can be obtained, is indispensably necessary to every law, by which the whole people are to be bound; else the whole people are enslaved to the one, or the few, who frame the laws for them.
