Variant: The God who gave us life gave us liberty at the same time; the hand of force may destroy, but cannot disjoin them.

Letter to William Charles Jarvis (1820)
1820s
Context: You seem to consider the federal judges as the ultimate arbiters of all constitutional questions, a very dangerous doctrine, indeed, and one which would place us under the despotism of an oligarchy. Our judges are as honest as other men, and not more so. They have with others the same passions for the party, for power and the privilege of the corps. Their power is the more dangerous, as they are in office for life and not responsible, as the other functionaries are, to the elective control. The Constitution has erected no such single tribunal, knowing that to whatever hands confided, with the corruptions of time and party, its members would become despots. It has more wisely made all departments co-equal and co-sovereign within themselves.

The sentence "I hope our wisdom will grow with our power, and teach us, that the less we use our power, the greater it will be." was used by US-President Barack Obama in his A New Beginning Speech.
1810s
Context: We concur in considering the government of England as totally without morality, insolent beyond bearing, inflated with vanity and ambition, aiming at the exclusive dominion of the sea, lost in corruption, of deep-rooted hatred towards us, hostile to liberty wherever it endeavors to show its head, and the eternal disturber of the peace of the world. In our estimate of Bonaparte, I suspect we differ. [... ] Our form of government is odious to him, as a standing contrast between republican and despotic rule; and as much from that hatred, as from ignorance in political economy, he had excluded intercourse between us and his people, by prohibiting the only articles they wanted from us, that is, cotton and tobacco. Whether the war we have had with England, and the achievements of that war, and the hope that we may become his instruments and partisans against that enemy, may induce him, in future, to tolerate our commercial intercourse with his people, is still to be seen. For my part, I wish that all nations may recover and retain their independence; that those which are overgrown may not advance beyond safe measures of power, that a salutary balance may be ever maintained among nations, and that our peace, commerce, and friendship, may be sought and cultivated by all. It is our business to manufacture for ourselves whatever we can, to keep our markets open for what we can spare or want; and the less we have to do with the amities or enmities of Europe, the better. Not in our day, but at no distant one, we may shake a rod over the heads of all, which may make the stoutest of them tremble. But I hope our wisdom will grow with our power, and teach us, that the less we use our power, the greater it will be.

1810s
Context: Our legislators are not sufficiently apprized of the rightful limits of their power; that their true office is to declare and enforce only our natural rights and duties, and to take none of them from us. No man has a natural right to commit aggression on the equal rights of another; and this is all from which the laws ought to restrain him; every man is under the natural duty of contributing to the necessities of the society; and this is all the laws should enforce on him; and, no man having a natural right to be the judge between himself and another, it is his natural duty to submit to the umpirage of an impartial third. When the laws have declared and enforced all this, they have fulfilled their functions, and the idea is quite unfounded, that on entering into society we give up any natural right.

Letter to John Page (15 July 1763); published in The Works of Thomas Jefferson (1905)
1760s
Context: The most fortunate of us, in our journey through life, frequently meet with calamities and misfortunes which may greatly afflict us; and, to fortify our minds against the attacks of these calamities and misfortunes, should be one of the principal studies and endeavours of our lives. The only method of doing this is to assume a perfect resignation to the Divine will, to consider that whatever does happen, must happen; and that by our uneasiness, we cannot prevent the blow before it does fall, but we may add to its force after it has fallen. These considerations, and others such as these, may enable us in some measure to surmount the difficulties thrown in our way; to bear up with a tolerable degree of patience under this burthen of life; and to proceed with a pious and unshaken resignation, till we arrive at our journey’s end, when we may deliver up our trust into the hands of him who gave it, and receive such reward as to him shall seem proportioned to our merit. Such, dear Page, will be the language of the man who considers his situation in this life, and such should be the language of every man who would wish to render that situation as easy as the nature of it will admit. Few things will disturb him at all: nothing will disturb him much.

Letter to Oliver Evans (16 January 1814); published in The Writings of Thomas Jefferson (1905) Vol. 13, p. 66
1810s
Context: A man has a right to use a saw, an axe, a plane, separately; may he not combine their uses on the same piece of wood? He has a right to use his knife to cut his meat, a fork to hold it; may a patentee take from him the right to combine their use on the same subject? Such a law, instead of enlarging our conveniences, as was intended, would most fearfully abridge them, and crowd us by monopolies out of the use of the things we have.

1810s, Letter to H. Tompkinson (AKA Samuel Kercheval) (1816)
Context: I am not among those who fear the people. They, and not the rich, are our dependence for continued freedom. And to preserve their independence, we must not let our rulers load us with perpetual debt. We must make our election between economy and liberty, or profusion and servitude. If we run into such debts, as that we must be taxed in our meat and in our drink, in our necessaries and our comforts, in our labors and our amusements, for our callings and our creeds, as the people of England are, our people, like them, must come to labor sixteen hours in the twenty-four, give the earnings of fifteen of these to the government for their debts and daily expenses; and the sixteenth being insufficient to afford us bread, we must live, as they now do, on oatmeal and potatoes; have no time to think, no means of calling the mismanagers to account; but be glad to obtain subsistence by hiring ourselves to rivet their chains on the necks of our fellow-sufferers. Our landholders, too, like theirs, retaining indeed the title and stewardship of estates called theirs, but held really in trust for the treasury, must wander, like theirs, in foreign countries, and be contented with penury, obscurity, exile, and the glory of the nation. This example reads to us the salutary lesson, that private fortunes are destroyed by public as well as by private extravagance. And this is the tendency of all human governments. A departure from principle in one instance becomes a precedent for a second; that second for a third; and so on, till the bulk of the society is reduced to be mere automatons of misery, and to have no sensibilities left but for sinning and suffering. Then begins, indeed, the bellum omnium in omnia, which some philosophers observing to be so general in this world, have mistaken it for the natural, instead of the abusive state of man. And the fore horse of this frightful team is public debt. Taxation follows that, and in its train wretchedness and oppression.

Letter to Francis Adrian Van der Kemp (30 July 1816), denouncing the doctrine of the Trinity.
1810s
Context: Ridicule is the only weapon which can be used against unintelligible propositions. Ideas must be distinct before reason can act upon them; and no man ever had a distinct idea of the trinity. It is the mere Abracadabra of the mountebanks calling themselves the priests of Jesus.

Thus in France the emetic was once forbidden as a medicine, and the potatoe as an article of food.

1780s, Letter to Peter Carr (1787)
Context: When speaking of the new testament that you should read all the histories of Christ, as well of those whom a council of ecclesiastics have decided for us to be Pseudo-evangelists, as those they named Evangelists. Because these Pseudo-evangelists pretended to inspiration as much as the others, and you are to judge their pretensions by your own reason, & not by the reason of those ecclesiastics. Most of these are lost. There are some however still extant, collected by Fabricius which I will endeavor to get & send you.

1820s
Context: I thank you, Sir, for the copy you were so kind as to send me of the revd. Mr. Bancroft's Unitarian sermons. I have read them with great satisfaction, and always rejoice in efforts to restore us to primitive Christianity, in all the simplicity in which it came from the lips of Jesus. Had it never been sophisticated by the subtleties of Commentators, nor paraphrased into meanings totally foreign to its character, it would at this day have been the religion of the whole civilized world. But the metaphysical abstractions of Athanasius, and the maniac ravings of Calvin, tinctured plentifully with the foggy dreams of Plato, have so loaded it with absurdities and incomprehensibilities, as to drive into infidelity men who had not time, patience, or opportunity to strip it of its meretricious trappings[. ]

1780s, Letter to Peter Carr (1787)
Context: He who made us would have been a pitiful bungler, if he had made the rules of our moral conduct a matter of science. For one man of science, there are thousands who are not. What would have become of them? Man was destined for society. His morality, therefore, was to be formed to this object. He was endowed with a sense of right and wrong, merely relative to this.
