This and similar lines in Adolf Hitler's Mein Kampf about what he claimed to be a strategem of Jewish lies using "the principle & which is quite true in itself & that in the big lie there is always a certain force of credibility; because the broad masses of a nation are always more easily corrupted in the deeper strata of their emotional nature than consciously or voluntarily," are often misquoted or paraphrased as: "The bigger the lie, the more it will be believed."

1910s, Address to the Knights of Columbus (1915)
Context: One of the most important things to secure for him is the right to hold and to express the religious views that best meet his own soul needs. Any political movement directed against anybody of our fellow- citizens because of their religious creed is a grave offense against American principles and American institutions. It is a wicked thing either to support or to oppose a man because of the creed he professes. This applies to Jew and Gentile, to Catholic and Protestant, and to the man who would be regarded as unorthodox by all of them alike. Political movements directed against men because of their religious belief, and intended to prevent men of that creed from holding office, have never accomplished anything but harm. This was true in the days of the ‘Know-Nothing’ and Native-American parties in the middle of the last century; and it is just as true to-day. Such a movement directly contravenes the spirit of the Constitution itself. Washington and his associates believed that it was essential to the existence of this Republic that there should never be any union of Church and State; and such union is partially accomplished wherever a given creed is aided by the State or when any public servant is elected or defeated because of his creed. The Constitution explicitly forbids the requiring of any religious test as a qualification for holding office. To impose such a test by popular vote is as bad as to impose it by law. To vote either for or against a man because of his creed is to impose upon him a religious test and is a clear violation of the spirit of the Constitution.

Budokwai Bulletin (1947)
Context: I have been asked by people of various sections as to the wisdom and possibility of Judo being introduced with other games and sports at the Olympic Games. My view on the matter, at present, is rather passive. If it be the desire of other member countries, I have no objection. But I do not feel inclined to take any initiative. For one thing, Judo in reality is not a mere sport or game. I regard it as a principle of life, art and science. In fact, it is a means for personal cultural attainment. Only one of the forms of Judo training, so-called randori or free practice can be classed as a form of sport. Certainly, to some extent, the same may be said of boxing and fencing, but today they are practiced and conducted as sports. Then the Olympic Games are so strongly flavored with nationalism that it is possible to be influenced by it and to develop "Contest Judo", a retrograde form as ju-jitsu was before the Kodokan was founded.

The Crisis No. I.
1770s, The American Crisis (1776–1783)
Context: It matters not where you live, or what rank of life you hold, the evil or the blessing will reach you all. The far and the near, the home counties and the back, the rich and the poor, will suffer or rejoice alike. The heart that feels not now is dead; the blood of his children will curse his cowardice, who shrinks back at a time when a little might have saved the whole, and made them happy. I love the man that can smile in trouble, that can gather strength from distress, and grow brave by reflection. 'Tis the business of little minds to shrink; but he whose heart is firm, and whose conscience approves his conduct, will pursue his principles unto death.
My own line of reasoning is to myself as straight and clear as a ray of light. Not all the treasures of the world, so far as I believe, could have induced me to support an offensive war, for I think it murder; but if a thief breaks into my house, burns and destroys my property, and kills or threatens to kill me, or those that are in it, and to "bind me in all cases whatsoever" to his absolute will, am I to suffer it? What signifies it to me, whether he who does it is a king or a common man; my countryman or not my countryman; whether it be done by an individual villain, or an army of them? If we reason to the root of things we shall find no difference; neither can any just cause be assigned why we should punish in the one case and pardon in the other. Let them call me rebel and welcome, I feel no concern from it; but I should suffer the misery of devils, were I to make a whore of my soul by swearing allegiance to one whose character is that of a sottish, stupid, stubborn, worthless, brutish man.

The Art of Persuasion

These expressions, different in form, are identical in object and effect — the supplanting the principles of free government, and restoring those of classification, caste and legitimacy. They would delight a convocation of crowned heads plotting against the people. They are the vanguard, the miner and sappers, of returning despotism. We must repulse them, or they will subjugate us.

Source: Morals and Dogma of the Ancient and Accepted Scottish Rite of Freemasonry (1871), Ch. XXII : Grand Master Architect, p. 194
Context: To the gentle, many will be gentle; to the kind, many will be kind. A good man will find that there is goodness in the world; an honest man will find that there is honesty in the world; and a man of principle will find principle and integrity in the hearts of others.
There are no blessings which the mind may not convert into the bitterest of evils; and no trials which it may not transform into the noblest and divinest blessings. There are no temptations from which assailed virtue may not gain strength, instead of falling before them, vanquished and subdued.

Hérodiade.
Hérodiade (1898)
Context: I feel in my sinews
The spreading of shadows
Converging together
With a shiver
And in solitary vigil
After flights triumphal
My head rise
From this scythe
Through a clean rupture
That serves to dissever
The ancient disharmony
With the body
As drunk from fasting
It persists in following
With a haggard bound
Its gaze profound
Up where the frozen
Absolute has chosen
That nothing shall measure
Its vastness, O glacier
But according to a ritual
Illumined by the principle
That chose my consecration
It extends a salutation.

Source: 1790s, The Age of Reason, Part II (1795), Chapter III: Conclusion.
Context: The study of theology as it stands in Christian churches, is the study of nothing; it is founded on nothing; it rests on no principles; it proceeds by no authorities; it has no data; it can demonstrate nothing; and admits of no conclusion. Not any thing can be studied as a science without our being in possession of the principles upon which it is founded; and as this is not the case with Christian theology, it is therefore the study of nothing.

1790s
Context: !-- Revd Sir I have your favor of the 17th instant before me; and my only motive to trouble you with the receipt of this letter, is to explain, and correct a mistake which I perceive the hurry in which I am obliged, often, to write letters, have led you into.

The Art of Peace (1992)
Context: The Art of Peace is the principle of nonresistance. Because it is nonresistant, it is victorious from the beginning. Those with evil intentions or contentious thoughts are instantly vanquished. The Art of Peace is invincible because it contends with nothing.

“From the Cataphrygians these principles and practices were propagated down to posterity”
Vol. I, Ch. 13: Of the King who did according to his will, and magnified himself above every God, and honored Mahuzzims, and regarded not the desire of women
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: The Cataphrygians brought in also several other superstitions: such as were the doctrine of Ghosts, and of their punishment in Purgatory, with prayers and oblations for mitigating that punishment, as Tertullian teaches in his books De Anima and De Monogamia. They used also the sign of the cross as a charm. So Tertullian in his book de Corona militis... All these superstitions the Apostle refers to, where he saith: Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils, the Dæmons and Ghosts worshiped by the heathens, speaking lies in hypocrisy, about their apparitions, the miracles done by them, their relics, and the sign of the cross, having consciences seared with a hot iron; forbidding to marry, and commanding to abstain from meats, &c. 1 Tim. iv. 1,2,3. From the Cataphrygians these principles and practices were propagated down to posterity. For the mystery of iniquity did already work in the Apostles days in the Gnostics, continued to work very strongly in their offspring the Tatianists and Cataphrygians, and was to work till that man of sin should be revealed; whose coming is after the working of Satan, with all power and signs, and lying wonders, and all deceivableness of unrighteousness; colored over with a form of Christian godliness, but without the power thereof, 2 Thess. ii. 7-10.

Vol. I, Ch. 13: Of the King who did according to his will, and magnified himself above every God, and honored Mahuzzims, and regarded not the desire of women
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: Hitherto the principles of the Encratites had been rejected by the Churches; but now being refined by the Monks, and imposed not upon all men, but only upon those who would voluntarily undertake a monastic life, they began to be admired, and to overflow first the Greek Church, and then the Latin also, like a torrent. Eusebius tells us, that Constantine the great had those men in the highest veneration, who dedicated themselves wholly to the divine philosophy; and that he almost venerated the most holy company of Virgins perpetually devoted to God; being certain that the God to whom he had consecrated himself did dwell in their minds. In his time and that of his sons, this profession of a single life was propagated in Egypt by Antony, and in Syria by Hilarion; and spread so fast, that soon after the time of Julian the Apostate a third part of the Egyptians were got into the deserts of Egypt. They lived first singly in cells, then associated into cœnobia or convents; and at length came into towns, and filled the Churches with Bishops, Presbyters and Deacons. Athanasius in his younger days poured water upon the hands of his master Antony; and finding the Monks faithful to him, made many of them Bishops and Presbyters in Egypt: and these Bishops erected new Monasteries, out of which they chose Presbyters of their own cities, and sent Bishops to others. The like was done in Syria, the superstition being quickly propagated thither out of Egypt by Hilarion a disciple of Antony. Spiridion and Epiphanius of Cyprus, James of Nisibis, Cyril of Jerusalem, Eustathius of Sebastia in Armenia, Eusebius of Emisa, Titus of Bostra, Basilius of Ancyra, Acacius of Cæsarea in Palestine, Elpidius of Laodicea, Melitius and Flavian of Antioch, Theodorus of Tyre, Protogenes of Carrhæ, Acacius of Berrhæa, Theodotus of Hierapolis, Eusebius of Chalcedon, Amphilochius of Iconium, Gregory Nazianzen, Gregory Nyssen, and John Chrysostom of Constantinople, were both Bishops and Monks in the fourth century. Eustathius, Gregory Nazianzen, Gregory Nyssen, Basil, &c. had Monasteries of Clergymen in their cities, out of which Bishops were sent to other cities; who in like manner erected Monasteries there, till the Churches were supplied with Bishops out of these Monasteries.... Not long after even the Emperors commanded the Churches to choose Clergymen out of the Monasteries by this Law.

1850s, Speech at Chicago (1858)
Context: There is something else connected with it. We have besides these men — descended by blood from our ancestors — among us perhaps half our people who are not descendants at all of these men, they are men who have come from Europe — German, Irish, French and Scandinavian — men that have come from Europe themselves, or whose ancestors have come hither and settled here, finding themselves our equals in all things. If they look back through this history to trace their connection with those days by blood, they find they have none, they cannot carry themselves back into that glorious epoch and make themselves feel that they are part of us, but when they look through that old Declaration of Independence they find that those old men say that 'We hold these truths to be self-evident, that all men are created equal,' and then they feel that that moral sentiment taught in that day evidences their relation to those men, that it is the father of all moral principle in them, and that they have a right to claim it as though they were blood of the blood, and flesh of the flesh of the men who wrote that Declaration, and so they are. That is the electric cord in that Declaration that links the hearts of patriotic and liberty-loving men together, that will link those patriotic hearts as long as the love of freedom exists in the minds of men throughout the world.

Source: The Limits of State Action (1792), Ch. 6
Context: The grand, leading principle, towards which every argument hitherto unfolded in these pages directly converges, is the absolute and essential importance of human development in its richest diversity; but national education, since at least it presupposes the selection and appointment of some one instructor, must always promote a definite form of development, however careful to avoid such an error. And hence it is attended with all those disadvantages which we before observed to flow from such a positive policy; and it only remains to be added, that every restriction becomes more directly fatal, when it operates on the moral part of our nature,—that if there is one thing more than another which absolutely requires free activity on the part of the individual, it is precisely education, whose object it is to develop the individual.

“Man cannot make principles, he can only discover them.”
1790s, The Age of Reason, Part I (1794)
Context: It is a fraud of the Christian system to call the sciences human invention; it is only the application of them that is human. Every science has for its basis a system of principles as fixed and unalterable as those by which the universe is regulated and governed. Man cannot make principles, he can only discover them.

1860s, Speech in Independence Hall (1861)

2016, Young Leaders of the Americas Initiative Town Hall (March 2016)
Context: I believe that under the surface all people are the same. […] people are all essentially the same. Similar hopes, similar dreams, similar strengths, similar weaknesses. But we're also all bound by history and culture and habits. And so conflicts arise, in part, because of some weaknesses in human nature. When we feel threatened, then we like to strike out against people who are not like us. When change is happening too quickly, and we try to hang on to those things that we think could give us a solid foundation. And sometimes the organizing principles are around issues like race, or religion. When there are times of scarcity, then people can turn on each other. And so I don't underestimate the very real challenges that we continue to face, and I don't think it is inevitable that the world comes together in a common culture and common understanding. But overall, I am hopeful. And the reason I'm hopeful is, if you look at the trajectory of history, humanity has slowly improved.

Remarks by President Obama and President Kenyatta of Kenya in a Press Conference at Kenyan State House in Nairobi, Kenya https://www.whitehouse.gov/the-press-office/2015/07/25/remarks-president-obama-and-president-kenyatta-kenya-press-conference (July 25, 2015)
2015
Context: I believe in the principle of treating people equally under the law, and that they are deserving of equal protection under the law and that the state should not discriminate against people based on their sexual orientation. And I say that, recognizing that there may be people who have different religious or cultural beliefs. But the issue is how does the state operate relative to people. If you look at the history of countries around the world, when you start treating people differently -- not because of any harm they’re doing anybody, but because they’re different -- that’s the path whereby freedoms begin to erode and bad things happen. And when a government gets in the habit of treating people differently, those habits can spread. And as an African-American in the United States, I am painfully aware of the history of what happens when people are treated differently, under the law, and there were all sorts of rationalizations that were provided by the power structure for decades in the United States for segregation and Jim Crow and slavery, and they were wrong.

From the private journal of Secretary of State Adams (1820)
Context: The discussion of this Missouri question has betrayed the secret of their souls. In the abstract they admit that slavery is an evil, they disclaim it, and cast it all upon the shoulder of…Great Britain. But when probed to the quick upon it, they show at the bottom of their souls pride and vainglory in their condition of masterdom. They look down upon the simplicity of a Yankee’s manners, because he has no habits of overbearing like theirs and cannot treat negroes like dogs. It is among the evils of slavery that it taints the very sources of moral principle. It establishes false estimates of virtue and vice: for what can be more false and heartless than this doctrine which makes the first and holiest rights of humanity to depend upon the color of the skin?

Speech in reply to Senator Stephen Douglas in the Lincoln-Douglas debates http://www.bartleby.com/251/1003.html of the 1858 campaign for the U.S. Senate, at Chicago, Illinois (10 July 1858)
1850s, Lincoln–Douglas debates (1858)
Context: My friend has said to me that I am a poor hand to quote Scripture. I will try it again, however. It is said in one of the admonitions of our Lord, "As your Father in Heaven is perfect, be ye also perfect." The Saviour, I suppose, did not expect that any human creature could be perfect as the Father in Heaven; but He said, "As your Father in Heaven is perfect, be ye also perfect." He set that up as a standard; and he who did most toward reaching that standard, attained the highest degree of moral perfection. So I say in relation to the principle that all men are created equal, let it be as nearly reached as we can. If we cannot give freedom to every creature, let us do nothing that will impose slavery upon any other creature. Let us then turn this Government back into the channel in which the framers of the Constitution originally placed it. Let us stand firmly by each other. If we do not do so we are turning in the contrary direction, that our friend Judge Douglas proposes — not intentionally — as working in the traces tend to make this one universal slave nation. He is one that runs in that direction, and as such I resist him. My friends, I have detained you about as long as I desired to do, and I have only to say, let us discard all this quibbling about this man and the other man; this race and that race and the other race being inferior, and therefore they must be placed in an inferior position; discarding our standard that we have left us. Let us discard all these things, and unite as one people throughout this land, until we shall once more stand up declaring that all men are created equal. My friends, I could not, without launching off upon some new topic, which would detain you too long, continue to-night. I thank you for this most extensive audience that you have furnished me to-night. I leave you, hoping that the lamp of liberty will burn in your bosoms until there shall no longer be a doubt that all men are created free and equal.

During an after-dinner discussion in Munich https://books.google.com/books?id=2zxfyeUHKEAC&pg=PA69 (1933), regarding the American Civil War
Disputed, The Testament of Adolf Hitler (1945)
Context: This is the last disgusting death-rattle of a corrupt and outworn system which is a blot on the history of this people. Since the civil war, in which the southern states were conquered, against all historical logic and sound sense, the American people have been in a condition of political and popular decay. In that war, it was not the Southern States, but the American people themselves who were conquered. In this spurious blossoming of economic progress and power politics, America has ever since been drawn deeper into the mire of progressive self-destruction. The beginnings of a great new social order based on the principle of slavery and inequality were destroyed by that war, and with them also the embryo of a future truly great America that would not have been ruled by a corrupt caste of tradesmen, but by a real Herren-class that would have swept away all the falsities of liberty and equality.

1910s, Address to the Knights of Columbus (1915)
Context: Our nation was founded to perpetuate democratic principles. These principles are that each man is to be treated on his worth as a man without regard to the land from which his forefathers came and without regard to the creed which he professes. If the United States proves false to these principles of civil and religious liberty, it will have inflicted the greatest blow on the system of free popular government that has ever been inflicted. Here we have had a virgin continent on which to try the experiment of making out of divers race stocks a new nation and of treating all the citizens of that nation in such a fashion as to preserve them equality of opportunity in industrial, civil, and political life. Our duty is to secure each man against any injustice by his fellows.

Letter to Reverend G. W. Snyder (25 September 1798) http://founders.archives.gov/documents/Washington/06-02-02-0435 thanking him for a copy of Proofs of a Conspiracy against All the Religions and Governments of Europe (1798) by John Robison.
1790s
Context: I have heard much of the nefarious, & dangerous plan, & doctrines of the Illuminati, but never saw the Book until you were pleased to send it to me. The same causes which have prevented my acknowledging the receipt of your letter, have prevented my reading the Book, hitherto; namely — the multiplicity of matters which pressed upon me before, & the debilitated state in which I was left after, a severe fever had been removed. And which allows me to add little more now, than thanks for your kind wishes and favourable sentiments, except to correct an error you have run into, of my Presiding over the English lodges in this Country. The fact is, I preside over none, nor have I been in one more than once or twice, within the last thirty years. I believe notwithstandings, that none of the Lodges in this Country are contaminated with the principles ascribed to the Society of the Illuminati.

1850s, The House Divided speech (1858)
Context: Now, as ever, I wish not to misrepresent Judge Douglas's position, question his motives, or do aught that can be personally offensive to him. Whenever, if ever, he and we can come together on principle so that our cause may have assistance from his great ability, I hope to have interposed no adventitious obstacle. But clearly, he is not now with us — he does not pretend to be — he does not promise ever to be. Our cause, then, must be intrusted to, and conducted by, its own undoubted friends — those whose hands are free, whose hearts are in the work — who do care for the result.

Theoria motus corporum coelestium in sectionibus conicis solem ambientum (1809) Tr. Charles Henry Davis as Theory of the Motion of the Heavenly Bodies moving about the Sun in Conic Sections http://books.google.com/books?id=cspWAAAAMAAJ& (1857)
Context: The principle that the sum of the squares of the differences between the observed and computed quantities must be a minimum may, in the following manner, be considered independently of the calculus of probabilities. When the number of unknown quantities is equal to the number of the observed quantities depending on them, the former may be so determined as exactly to satisfy the latter. But when the number of the former is less than that of the latter, an absolutely exact agreement cannot be obtained, unless the observations possess absolute accuracy. In this case care must be taken to establish the best possible agreement, or to diminish as far as practicable the differences. This idea, however, from its nature, involves something vague. For, although a system of values for the unknown quantities which makes all the differences respectively less than another system, is without doubt to be preferred to the latter, still the choice between two systems, one of which presents a better agreement in some observations, the other in others, is left in a measure to our judgment, and innumerable different principles can be proposed by which the former condition is satisfied. Denoting the differences between observation and calculation by A, A’, A’’, etc., the first condition will be satisfied not only if AA + A’ A’ + A’’ A’’ + etc., is a minimum (which is our principle) but also if A4 + A’4 + A’’4 + etc., or A6 + A’6 + A’’6 + etc., or in general, if the sum of any of the powers with an even exponent becomes a minimum. But of all these principles ours is the most simple; by the others we should be led into the most complicated calculations.

Under Fire (1916), Ch. 24 - The Dawn
Context: I tell them that fraternity is a dream, an obscure and uncertain sentiment; that while it is unnatural for a man to hate one whom he does not know, it is equally unnatural to love him. You can build nothing on fraternity. Nor on liberty, either; it is too relative a thing in a society where all the elements subdivide each other by force.
But equality is always the same. Liberty and fraternity are words while equality is a fact. Equality should be the great human formula — social equality, for while individuals have varying values, each must have an equal share in the social life; and that is only just, because the life of one human being is equal to the life of another. That formula is of prodigious importance. The principle of the equal rights of every living being and the sacred will of the majority is infallible and must be invincible; all progress will be brought about by it, all, with a force truly divine. It will bring first the smooth bed-rock of all progress — the settling of quarrels by that justice which is exactly the same thing as the general advantage.

1980s, First term of office (1981–1985)
Context: Abraham Lincoln freed the black man. In many ways, Dr. King freed the white man. How did he accomplish this tremendous feat? Where others — white and black — preached hatred, he taught the principles of love and nonviolence. We can be so thankful that Dr. King raised his mighty eloquence for love and hope rather than for hostility and bitterness. He took the tension he found in our nation, a tension of injustice, and channeled it for the good of America and all her people.

Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: For though some stop was put to the Cataphrygian Christianity, by Provincial Councils, till the fourth century; yet the Roman Emperors then turning Christians, and great multitudes of heathens coming over in outward profession, these found the Cataphrygian Christianity more suitable to their old principles, of placing religion in outward forms and ceremonies, holy-days, and doctrines of Ghosts, than the religion of the sincere Christians: wherefore they readily sided with the Cataphrygian Christians, and established that Christianity before the end of the fourth century. By this means those of understanding, after they had been persecuted by the heathen Emperors in the three first centuries, and were holpen with a little help, by the conversion of Constantine the great and his sons to the Christian religion, fell under new persecutions, to purge them from the dissemblers, and to make them white, even to the time of the end.

“The principle itself is one of disintegration, and upon which no government can possibly endure”
1860s, Fourth of July Address to Congress (1861)
Context: The seceders insist that our Constitution admits of secession. They have assumed to make a national constitution of their own, in which of necessity they have either discarded or retained the right of secession, as they insist it exists in ours. If they have discarded it, they thereby admit that on principle it ought not to be in ours. If they have retained it, by their own construction of ours they show that to be consistent they must secede from one another whenever they shall find it the easiest way of settling their debts or effecting any other selfish or unjust object. The principle itself is one of disintegration, and upon which no government can possibly endure.

Context: The concept of justice I take to be defined, then, by the role of its principles in assigning rights and duties and in defining the appropriate division of social advantages. A conception of justice is an interpretation of this role.

Pupils at Sais (1799)
Context: If on the one hand the Scholastics and Alchemists seem to be utterly at variance, and the Eclectics on the other hand quite at one, yet, strictly examined, it is altogether the reverse. The former, in essentials, are indirectly of one opinion; namely, as regards the non-dependence, and infinite character of Meditation, they both set out from the Absolute: whilst the Eclectic and limited sort are essentially at variance; and agree only in what is deduced. The former are infinite but uniform, the latter bounded but multiform; the former have genius, the latter talent; those have Ideas, these have knacks (Handgriffe); those are heads without hands, these are hands without heads. The third stage is for the Artist, who can be at once implement and genius. He finds that that primitive Separation in the absolute Philosophical Activities' (between the Scholastic, and the "rude, intuitive Poet") 'is a deeper-lying Separation in his own Nature; which Separation indicates, by its existence as such, the possibility of being adjusted, of being joined: he finds that, heterogeneous as these Activities are, there is yet a faculty in him of passing from the one to the other, of changing his polarity at will. He discovers in them, therefore, necessary members of his spirit; he observes that both must be united in some common Principle. He infers that Eclecticism is nothing but the imperfect defective employment of this principle.

1790s, Letter to the Addressers (1792)
Context: It is from a strange mixture of tyranny and cowardice that exclusions have been set up and continued. The boldness to do wrong at first, changes afterwards into cowardly craft, and at last into fear. The Representatives in England appear now to act as if they were afraid to do right, even in part, lest it should awaken the nation to a sense of all the wrongs it has endured. This case serves to shew that the same conduct that best constitutes the safety of an individual, namely, a strict adherence to principle, constitutes also the safety of a Government, and that without it safety is but an empty name. When the rich plunder the poor of his rights, it becomes an example of the poor to plunder the rich of his property, for the rights of the one are as much property to him as wealth is property to the other and the little all is as dear as the much. It is only by setting out on just principles that men are trained to be just to each other; and it will always be found, that when the rich protect the rights of the poor, the poor will protect the property of the rich. But the guarantee, to be effectual, must be parliamentarily reciprocal.

“I am principled against this kind of traffic in the human species.”
Letter to Robert Lewis, 18 August 1799, published in John Clement Fitzpatrick, The writings of George Washington from the original manuscript sources, volume 37, pp. 338-9
1790s
Context: To sell the overplus I cannot, because I am principled against this kind of traffic in the human species. To hire them out, is almost as bad, because they could not be disposed of in families to any advantage, and to disperse the families I have an aversion. What then is to be done? Something must or I shall be ruined; for all the money (in addition to what I raise by Crops, and rents) that have been received for Lands, sold within the last four years, to the amount of Fifty thousand dollars, has scarcely been able to keep me a float.
