Ninety-Three (1874)
Context: Cimourdain was one of those men who have a voice within them, and who listen to it. Such men seem absent-minded; they are not; they are all attention.
Cimourdain knew everything and nothing. He knew everything about science, and nothing at all about life. Hence his inflexibility. His eyes were bandaged like Homer's Themis. He had the blind certainty of the arrow, which sees only the mark and flies to it. In a revolution, nothing is more terrible than a straight line. Cimourdain went straight ahead, as sure as fate.
Cimourdain believed that, in social geneses, the extreme point is the solid earth; an error peculiar to minds which replace reason with logic.

Context: If you find the light of Scripture clearer than the light of reason (which also is given us by divine wisdom), you are doubtless right in your own conscience in making your reason yield. For my part, since I plainly confess that I do not understand the Scriptures, though I have spent many years upon them, and since I know that when once I have a firm proof I cannot by any course of thought come to doubt of it, I rest wholly upon that which my understanding commends to me, without any suspicion that I am deceived therein, or that the Scriptures, even though I do not search them, can speak against it. For one truth cannot conflict with another, as I have already clearly shown in my Appendix to the "Principles of Descartes"... But if in any case I did find error in that which I have collected from my natural understanding, I should count it good fortune, since I enjoy life, and endeavour to pass it not in weeping and sighing, but in peace, joy, and cheerfulness, and from time to time climb thereby a step higher. I know, meanwhile (which is the highest pleasure of all), that all things happen by the power and unchangeable decree of the most perfect Being.

Context: Truth, indeed, is something that is believed in completely only by persons who have never tried personally to pursue it to its fastness and grab it by the tail. It is the adoration of second-rate men — men who always receive it as second-hand. Pedagogues believe in immutable truths and spend their lives trying to determine them and propagate them; the intellectual progress of man consists largely of a concerted effort to block and destroy their enterprise. Nine times out of ten, in the arts as in life, there is actually no truth to be discovered; there is only error to be exposed. In whole departments of human inquiry it seems to me quite unlikely that the truth ever will be discovered. Nevertheless, the rubber-stamp thinking of the world always makes the assumption that the exposure of an error is identical with the discovery of truth — that error and truth are simply opposites. They are nothing of the sort. What the world turns to, when it has been cured of one error, is usually simply another error, and maybe one worse than the first one. This is the whole history of the intellect in brief. The average man of today does not believe in precisely the same imbecilities that the Greek of the Fourth Century before Christ believed in, but the things that he does believe in are often quite as idiotic.
Perhaps this statement is a bit too sweeping. There is, year by year, a gradual accumulation of what may be called, provisionally, truths — there is a slow accretion of ideas that somehow manage to meet all practicable human tests, and so survive. But even so, it is risky to call them absolute truths. All that one may safely say of them is that no one, as yet, has demonstrated that they are errors. Soon or late, if experience teaches us anything, they are likely to succumb too. The profoundest truths of the Middle Ages are now laughed at by schoolboys. The profoundest truths of democracy will be laughed at, a few centuries hence, even by school-teachers.

Book I, v, 11
The Advancement of Learning (1605)
Context: The greatest error of all the rest is the mistaking or misplacing of the last or farthest end of knowledge: for men have entered into a desire of learning and knowledge, sometimes upon a natural curiosity and inquisitive appetite; sometimes to entertain their minds with variety and delight; sometimes for ornament and reputation; and sometimes to enable them to victory of wit and contradiction; and most times for lucre and profession; and seldom sincerely to give a true account of their gift of reason, to the benefit and use of men: as if there were sought in knowledge a couch whereupon to rest a searching and restless spirit; or a tarrasse, for a wandering and variable mind to walk up and down with a fair prospect; or a tower of state, for a proud mind to raise itself upon; or a fort or commanding ground, for strife and contention; or a shop, for profit or sale; and not a rich storehouse, for the glory of the Creator and the relief of man's estate.

Crabbed Age and Youth.
Virginibus Puerisque and Other Papers (1881)
Context: All error, not merely verbal, is a strong way of stating that the current truth is incomplete. The follies of youth have a basis in sound reason, just as much as the embarrassing questions put by babes and sucklings. Their most antisocial acts indicate the defects of our society. When the torrent sweeps the man against a boulder, you must expect him to scream, and you need not be surprised if the scream is sometimes a theory. Shelley, chafing at the Church of England, discovered the cure of all evils in universal atheism. Generous lads irritated at the injustices of society, see nothing for it but the abolishment of everything and Kingdom Come of anarchy. Shelley was a young fool; so are these cocksparrow revolutionaries. But it is better to be a fool than to be dead. It is better to emit a scream in the shape of a theory than to be entirely insensible to the jars and incongruities of life and take everything as it comes in a forlorn stupidity. Some people swallow the universe like a pill; they travel on through the world, like smiling images pushed from behind. For God’s sake give me the young man who has brains enough to make a fool of himself! As for the others, the irony of facts shall take it out of their hands, and make fools of them in downright earnest, ere the farce be over. There shall be such a mopping and a mowing at the last day, and such blushing and confusion of countenance for all those who have been wise in their own esteem, and have not learnt the rough lessons that youth hands on to age. If we are indeed here to perfect and complete our own natures, and grow larger, stronger, and more sympathetic against some nobler career in the future, we had all best bestir ourselves to the utmost while we have the time. To equip a dull, respectable person with wings would be but to make a parody of an angel.

Source: Conjectures and Refutations: The Growth of Scientific Knowledge (1963), Ch. 1 "Science : Conjectures and Refutations"
Context: The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities — perhaps the only one — in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there.

Source: Guide for the Perplexed (c. 1190), Part III, Ch.12
Context: The error of the ignorant goes so far as to say that God's power is insufficient, because he has given to this Universe the properties which they imagine cause these great evils, and which do not help all evil-disposed persons to obtain the evil which they seek, and to bring their evil souls to the aim of their desires, though these, as we have shown, are really without limit.

Notes on Religion (October 1776), published in The Writings of Thomas Jefferson : 1816–1826 (1899) edited by Paul Leicester Ford, v. 2, p. 102
1770s
Context: Truth will do well enough if left to shift for herself. She seldom has received much aid from the power of great men to whom she is rarely known & seldom welcome. She has no need of force to procure entrance into the minds of men. Error indeed has often prevailed by the assistance of power or force. Truth is the proper & sufficient antagonist to error.

De Abaitua interview (1998)
Context: As I understand, or as I hallucinate conceptual space, nearly all form in conceptual space is language, I might even say all the form in non-conceptual space is language, I’m not even sure of what the difference between physical space and conceptual space is anymore, in the interface. All form is language. The forms that we see, or imagine, or perceive, or whatever it is Remote Viewers are doing, in conceptual space are mindforms made from language, and by language I also mean images, sounds. We dress these basic ideas in language we can understand. Sometimes there are sizable errors of translation.

James Clerk Maxwell, Matter and Motion (1876)
Context: Descartes... fell back on his original confusion of matter with space—space being, according to him, the only form of substance, and all existing things but affections of space. This error... forms one of the ultimate foundations of the system of Spinoza.

Academy of Achievement interview (1991)
Context: The idea of being constructive, creative, positive, in trying to bring out the best in one's own self and the best in others follows from what I've just been saying. Again, I repeat my belief in us, in ourselves, as the product of the process of evolution, and part of the process itself. I think of evolution as an error-making and error-correcting process, and we are constantly learning from experience. It's the need to dedicate one's self in that way, to one's own self, and to choose an activity or life that is of value not only to yourself but to others as well.

From Critique of Everyday Life: Volume 1 (1947/1991)
Context: Everything great and splendid is founded on power and wealth. They are the basis of beauty. This is why the rebel and the anarchic protester who decries all of history and all the works of past centuries because he sees in them only the skills and the threat of domination is making a mistake. He sees alienated forms, but not the greatness within. The rebel can only see to the end of his own ‘private’ consciousness, which he levels against everything human, confusing the oppressors with the oppressed masses, who were nevertheless the basis and the meaning of history and past works. Castles, palaces, cathedrals, fortresses, all speak in their various ways of the greatness and the strength of the people who built them and against whom they were built. This real greatness shines through the fake grandeur of rulers and endows these buildings with a lasting ‘beauty’. The bourgeoisie is alone in having given its buildings a single, over-obvious meaning, impoverished, deprived of reality: that meaning is abstract wealth and brutal domination; that is why it has succeeded in producing perfect ugliness and perfect vulgarity. The man who denigrates the past, and who nearly always denigrates the present and the future as well, cannot understand this dialectic of art, this dual character of works and of history. He does not even sense it. Protesting against bourgeois stupidity and oppression, the anarchic individualist is enclosed in ‘private’ consciousness, itself a product of the bourgeois era, and no longer understands human power and the community upon which that power is founded. The historical forms of this community, from the village to the nation, escape him. He is, and only wants to be, a human atom (in the scientifically archaic sense of the word, where ‘atom’ meant the lowest isolatable reality). By following alienation to its very extremes he is merely playing into the hands of the bourgeoisie. Embryonic and unconscious, this kind of anarchism is very widespread. There is a kind of revolt, a kind of criticism of life, that implies and results in the acceptance of this life as the only one possible. As a direct consequence this attitude precludes any understanding of what is humanly possible.

È poco male
Quel fallo poi che al fin in ben riesse.
Act V (Filarco).

Errori d’Amore

"On Freedom" in All Life is Problem Solving (1999)
Context: When I speak of reason or rationalism, all I mean is the conviction that we can learn through criticism of our mistakes and errors, especially through criticism by others, and eventually also through self-criticism. A rationalist is simply someone for whom it is more important to learn than to be proved right; someone who is willing to learn from others — not by simply taking over another's opinions, but by gladly allowing others to criticize his ideas and by gladly criticizing the ideas of others. The emphasis here is on the idea of criticism or, to be more precise, critical discussion. The genuine rationalist does not think that he or anyone else is in possession of the truth; nor does he think that mere criticism as such helps us achieve new ideas. But he does think that, in the sphere of ideas, only critical discussion can help us sort the wheat from the chaff. He is well aware that acceptance or rejection of an idea is never a purely rational matter; but he thinks that only critical discussion can give us the maturity to see an idea from more and more sides and to make a correct judgement of it.

FDA: Friend of Foe?
Context: If FDA officials err on the side of under-caution in approving an unsafe drug, they are attacked by the media and patient groups, and investigated by Congress. Their victims, sick and dead people, are highly visible. If FDA officials err on the side of over-caution, keeping a safe and effective drug off the market, who's to know? The victims are invisible. For example, neither the Americans who get sick or die from meningitis C this year, nor their loved ones, will know that their illness or death could have been prevented had it not been for errors by FDA officials. It's a no-brainer to figure out which error FDA officials prefer to make.

On Literature, Revolution, Entropy and Other Matters (1923)
Context: It is an error to divide people into the living and the dead: there are people who are dead-alive, and people who are alive-alive. The dead-alive also write, walk, speak, act. But they make no mistakes; only machines make no mistakes, and they produce only dead things. The alive-alive are constantly in error, in search, in questions, in torment.
The same is true of what we write: it walks and it talks, but it can be dead-alive or alive-alive. What is truly alive stops before nothing and ceaselessly seeks answers to absurd, "childish" questions. Let the answers be wrong, let the philosophy be mistaken — errors are more valuable than truths: truth is of the machine, error is alive; truth reassures, error disturbs. And if answers be impossible of attainment, all the better! Dealing with answered questions is the privilege of brains constructed like a cow's stomach, which, as we know, is built to digest cud.

1860s, Our Composite Nationality (1869)
Context: I need not repeat here the multitude of reproachful epithets expressive of the same sentiment among ourselves. All who are not to the manor born have been made to feel the lash and sting of these reproachful names. For this feeling there are many apologies, for there was never yet an error, however flagrant and hurtful, for which some plausible defense could not be framed. Chattel slavery, king craft, priest craft, pious frauds, intolerance, persecution, suicide, assassination, repudiation, and a thousand other errors and crimes have all had their defenses and apologies. Prejudice of race and color has been equally upheld. The two best arguments in the defense are, first, the worthlessness of the class against which it is directed; and, second, that the feeling itself is entirely natural. The way to overcome the first argument is to work for the elevation of those deemed worthless, and thus make them worthy of regard, and they will soon become worthy and not worthless. As to the natural argument, it may be said that nature has many sides. Many things are in a certain sense natural, which are neither wise nor best. It is natural to walk, but shall men therefore refuse to ride? It is natural to ride on horseback, shall men therefore refuse steam and rail? Civilization is itself a constant war upon some forces in nature, shall we therefore abandon civilization and go back to savage life? Nature has two voices, the one high, the other low; one is in sweet accord with reason and justice, and the other apparently at war with both. The more men know of the essential nature of things, and of the true relation of mankind, the freer they are from prejudice of every kind. The child is afraid of the giant form of his own shadow. This is natural, but he will part with his fears when he is older and wiser. So ignorance is full of prejudice, but it will disappear with enlightenment. But I pass on.

Source: How Europe Underdeveloped Africa (1972), p. 37.
Context: When the “experts” from capitalist countries do not give a racist explanation, they nevertheless confuse the issue by giving as causes of underdevelopment the things which really are consequences. For example, they would argue that Africa is in a state of backwardness as a result of lacking skilled personnel to develop. It is true that because of lack of engineers Africa cannot on its own build more roads, bridges, and hydroelectric stations. But that is not a cause of underdevelopment, except in the sense that causes and effects come together and reinforce each other. The fact of the matter is that the most profound reasons for the economic backwardness of a given African nation are not to be found inside that nation. All that we can find inside are the symptoms of underdevelopment and the secondary factors that make for poverty. Mistaken interpretations of the causes of underdevelopment usually stem either from prejudiced thinking or from the error of believing that one can learn the answers by looking inside the underdeveloped economy. The true explanation lies in seeking out the relationship between Africa and certain developed countries and in recognizing that it is a relationship of exploitation.

A New View of Society (1813-1816)
Context: All the measures now proposed are only a compromise with the errors of the present systems; but as these errors now almost universally exist, and must be overcome solely by the force of reason; and as reason, to effect the most beneficial purposes, makes her advance by slow degrees, and progressively substantiates one truth of high import after another, it will be evident, to minds of comprehensive and accurate thought, that by these and similar compromises alone can success be rationally expected in practice. For such compromises bring truth and error before the public; and whenever they are fairly exhibited together, truth must ultimately prevail.

Exsurge Domine (1520)
Context: No one of sound mind is ignorant how destructive, pernicious, scandalous, and seductive to pious and simple minds these various errors are, how opposed they are to all charity and reverence for the holy Roman Church who is the mother of all the faithful and teacher of the faith; how destructive they are of the vigor of ecclesiastical discipline, namely obedience. This virtue is the font and origin of all virtues and without it anyone is readily convicted of being unfaithful.
Therefore we, in this above enumeration, important as it is, wish to proceed with great care as is proper, and to cut off the advance of this plague and cancerous disease so it will not spread any further in the Lord's field as harmful thorn-bushes.

Source: Simone Weil : An Anthology (1986), Human Personality (1943), p. 69
Context: If a captive mind is unaware of being in prison, it is living in error. If it has recognized the fact, even for the tenth of a second, and then quickly forgotten it in order to avoid suffering, it is living in falsehood. Men of the most brilliant intelligence can be born, live and die in error and falsehood. In them, intelligence is neither a good, nor even an asset. The difference between more or less intelligent men is like the difference between criminals condemned to life imprisonment in smaller or larger cells. The intelligent man who is proud of his intelligence is like a condemned man who is proud of his large cell.

Our America (1881)
Context: The youth of America are rolling up their sleeves, digging their hands in the dough, and making it rise with the sweat of their brows. They realize that there is too much imitation, and that creation holds the key to salvation. "Create" is the password of this generation. The wine is made from plantain, but even if it turns sour, it is our own wine! That a country's form of government must be in keeping with its natural elements is a foregone conclusion. Absolute ideas must take relative forms if they are not to fail because of an error in form. Freedom, to be viable, has to be sincere and complete. If a republic refuses to open its arms to all, and move ahead with all, it dies.

Comment on establishing the University of Virginia, in a letter to Thomas Cooper (7 October 1814); published in The Writings of Thomas Jefferson (1905) edited by Andrew Adgate Lipscomb and Albert Ellery Bergh, Vol VII, p. 200 http://books.google.com/books?id=jrSgJGp-B64C&pg=RA1-PA200&dq=%22A+professorship+of+theology+should+have+no+place+in+our+institution%22&ei=u65FR562EpqCpwLkk9XxBg
1810s
Context: I agree … that a professorship of Theology should have no place in our institution. But we cannot always do what is absolutely best. Those with whom we act, entertaining different views, have the power and the right of carrying them into practice. Truth advances, and error recedes step by step only; and to do to our fellow men the most good in our power, we must lead where we can, follow where we cannot, and still go with them, watching always the favorable moment for helping them to another step.

Prologue as translated in Readings in European History, Vol. I (1904) edited by James Harvey Robinson, p. 450
Sic et Non (1120)
Context: Doubtless the fathers might err; even Peter, the prince of the apostles, fell into error: what wonder that the saints do not always show themselves inspired? The fathers did not themselves believe that they, or their companions, were always right. Augustine found himself mistaken in some cases and did not hesitate to retract his errors. He warns his admirers not to look upon his letters as they would upon the Scriptures, but to accept only those things which, upon examination, they find to be true.
All writings belonging to this class are to be read with full freedom to criticize, and with no obligation to accept unquestioningly; otherwise they way would be blocked to all discussion, and posterity be deprived of the excellent intellectual exercise of debating difficult questions of language and presentation.

Context: Justice in no wise consists in meting out to another that exact measure of reward or punishment which we think and decree his merit, or what we call his crime, which is more often merely his error, deserves. The justice of the father is not incompatible with forgiveness by him of the errors and offences of his child. The Infinite Justice of God does not consist in meting out exact measures of punishment for human frailties and sins. We are too apt to erect our own little and narrow notions of what is right and just, into the law of justice, and to insist that God shall adopt that as His law; to measure off something with our own little tape-line, and call it God's law of justice. Continually we seek to ennoble our own ignoble love of revenge and retaliation, by misnaming it justice.

Letter of Constantine to Sapor, King of the Persians (333)
Constantine the Great : Letters
Context: By keeping the Divine faith, I am made a partaker of the light of truth: guided by the light of truth, I advance in the knowledge of the Divine faith. Hence it is that, as my actions themselves evince, I profess the most holy religion; and this worship I declare to be that which teaches me deeper acquaintance with the most holy God; aided by whose Divine power, beginning from the very borders of the ocean, I have aroused each nation of the world in succession to a well-grounded hope of security; so that those which, groaning in servitude to the most cruel tyrants and yielding to the pressure of their daily sufferings, had well nigh been utterly destroyed, have been restored through my agency to a far happier state. This God I confess that I hold in unceasing honor and remembrance; this God I delight to contemplate with pure and guileless thoughts in the height of his glory. THIS God I invoke with bended knees, and recoil with horror from the blood of sacrifices from their foul and detestable odors, and from every earth-born magic fire: for the profane and impious superstitions which are defiled by these rites have cast down and consigned to perdition many, nay, whole nations of the Gentile world. For he who is Lord of all cannot endure that those blessings which, in his own loving-kindness and consideration of the wants of men he has revealed for the rise of all, should be perverted to serve the lusts of any. His only demand from man is purity of mind and an undefiled spirit; and by this standard he weighs the actions of virtue and godliness. For his pleasure is in works of moderation and gentleness: he loves the meek, and hates the turbulent spirit: delighting in faith, he chastises unbelief: by him all presumptuous power is broken down, and he avenges the insolence of the proud. While the arrogant and haughty are utterly overthrown, he requires the humble and forgiving with deserved rewards: even so does he highly honor and strengthen with his special help a kingdom justly governed, and maintains a prudent king in the tranquility of peace. I CANNOT, then, my brother believe that I err in acknowledging this one God, the author and parent of all things: whom many of my predecessors in power, led astray by the madness of error, have ventured to deny... For I myself have witnessed the end of those who lately harassed the worshipers of God by their impious edict. And for this abundant thanksgivings are due to God that through his excellent Providence all men who observe his holy laws are gladdened by the renewed enjoyment of peace. Hence I am fully persuaded that everything is in the best and safest posture, since God is vouchsafing, through the influence of their pure and faithful religious service, and their unity of judgment respecting his Divine character, to gather all men to himself

The Lifted Veil (1859); Eliot here quotes the Latin epitaph of Jonathan Swift, translated as "Where savage indignation can lacerate his heart no more" · The Lifted Veil online at Wikisource
Context: I wish to use my last hours of ease and strength in telling the strange story of my experience. I have never fully unbosomed myself to any human being; I have never been encouraged to trust much in the sympathy of my fellow-men. But we have all a chance of meeting with some pity, some tenderness, some charity, when we are dead: it is the living only who cannot be forgiven — the living only from whom men's indulgence and reverence are held off, like the rain by the hard east wind. While the heart beats, bruise it — it is your only opportunity; while the eye can still turn towards you with moist, timid entreaty, freeze it with an icy unanswering gaze; while the ear, that delicate messenger to the inmost sanctuary of the soul, can still take in the tones of kindness, put it off with hard civility, or sneering compliment, or envious affectation of indifference; while the creative brain can still throb with the sense of injustice, with the yearning for brotherly recognition — make haste — oppress it with your ill-considered judgements, your trivial comparisons, your careless misrepresentations. The heart will by and by be still — "ubi saeva indignatio ulterius cor lacerare nequit" the eye will cease to entreat; the ear will be deaf; the brain will have ceased from all wants as well as from all work. Then your charitable speeches may find vent; then you may remember and pity the toil and the struggle and the failure; then you may give due honour to the work achieved; then you may find extenuation for errors, and may consent to bury them.

Context: You can go to any major history and see the effect of unregulation. The very point of developing regulation around industrial society was that they were not only exploiting the workers to death they were befouling the planet, so regulation came because of that. What the right wing wants is for the public to have this role in the societal debate over balance of these issues and no power. The public power to confront these errors of industry is government regulation.

Preface of M. Quetelet
A Treatise on Man and the Development of His Faculties (1842)
Context: It would be an error... to suppose that science makes the artist; yet it lends to him the most powerful assistance. In general, it is difficult to keep it within due limits; and I shall even freely admit that Albert Durer, in his work upon the proportions of the human frame, has imparted to it a certain scientific dryness, which lessens its utility. One finds there more of the geometer than the artist, and the geometer, moreover, such as he was at a time when it had not yet been discovered how much the rules of style enhance the value of scientific works, and, above all, of those which appertain at the same time to the domain of the fine arts.

R.U.R. supplement in The Saturday Review (1923)
Context: Be these people either Conservatives or Socialists, Yellows or Reds, the most important thing is — and that is the point I want to stress — that all of them are right in the plain and moral sense of the word... I ask whether it is not possible to see in the present social conflict of the world an analogous struggle between two, three, five equally serious verities and equally generous idealisms? I think it is possible, and that is the most dramatic element in modern civilization, that a human truth is opposed to another human truth no less human, ideal against ideal, positive worth against worth no less positive, instead of the struggle being as we are so often told, one between noble truth and vile selfish error.

Fragments of Markham's notes
The Nemesis of Faith (1849)
Context: Finally rises philosophy, which, after a few monstrous efforts from Calvin to Leibnitz to reconcile contradictions and form a theodice, comes out boldly in Spinozism to declare the impossibility of the existence of a power antagonistic to God; and defining the perfection of man's nature, as the condition under which it has fullest action and freest enjoyment of all its powers, sets this as a moral ideal hefore us, toward which we shall train our moral efforts as the artist trains his artistic efforts towards his ideal. The success is various, as the faculties and conditions which God has given are various; but the spectre which haunted the conscience is gone. Our failures are errors, not crimes — nature's discipline with which God teaches us; and as little violations of His law, or rendering us guilty in His eyes, as the artist's early blunders, or even ultimate and entire failures, are laying store of guilt on him.

This has sometimes been paraphrased: "My failures have been errors of judgment, not of intent".
1870s, Eighth State of the Union Address (1876)
Context: I leave comparisons to history, claiming only that I have acted in every instance from a conscientious desire to do what was right, constitutional, within the law, and for the very best interests of the whole people. Failures have been errors of judgment, not of intent.

Query XVII
1780s, Notes on the State of Virginia
Context: Difference of opinion is advantageous in religion. The several sects perform the office of a Censor morum over each other. Is uniformity attainable? Millions of innocent men, women, and children, since the introduction of Christianity, have been burnt, tortured, fined, imprisoned; yet we have not advanced one inch towards uniformity. What has been the effect of coercion? To make one half the world fools, and the other half hypocrites. To support roguery and error all over the earth. Let us reflect that it is inhabited by a thousand millions of people. That these profess probably a thousand different systems of religion. That ours is but one of that thousand. That if there be but one right, and ours that one, we should wish to see the 999 wandering sects gathered into the fold of truth. But against such a majority we cannot effect this by force. Reason and persuasion are the only practicable instruments. To make way for these, free enquiry must be indulged; and how can we wish others to indulge it while we refuse it ourselves?

Source: The Theory of Political Economy (1871), Chapter VIII : Concluding Remarks, The Noxious Influence of Authority, p. 220.
Context: To me it is far more pleasant to agree than to differ; but it is impossible that one who has any regard for truth can long avoid protesting against doctrines which seem to him to be erroneous. There is ever a tendency of the most hurtful kind to allow opinions to crystallise into creeds. Especially does this tendency manifest itself when some eminent author, enjoying power of clear and comprehensive exposition, becomes recognised as an authority. His works may perhaps be the best which are extant upon the subject in question; they may combine more truth with less error than we can elsewhere meet. But "to err is human," and the best works should ever be open to criticism. If, instead of welcoming inquiry and criticism, the admirers of a great author accept his writings as authoritative, both in their excellences and in their defects, the most serious injury is done to truth. In matters of philosophy and science authority has ever been the great opponent of truth. A despotic calm is usually the triumph of error. In the republic of the sciences sedition and even anarchy are beneficial in the long run to the greatest happiness of the greatest number.

1800s, First Inaugural Address (1801)
Context: I shall often go wrong through defect of judgment. When right, I shall often be thought wrong by those whose positions will not command a view of the whole ground. I ask your indulgence for my own errors, which will never be intentional, and your support against the errors of others, who may condemn what they would not if seen in all its parts.

The Great Infidels (1881)
Context: All the martyrs in the history of the world are not sufficient to establish the correctness of an opinion. Martyrdom, as a rule, establishes the sincerity of the martyr, — never the correctness of his thought. Things are true or false in themselves. Truth cannot be affected by opinions; it cannot be changed, established, or affected by martyrdom. An error cannot be believed sincerely enough to make it a truth.

Letter to Mary Gladstone (1881)
Context: There is no error so monstrous that it fails to find defenders among the ablest men. Imagine a congress of eminent celebrities, such as More, Bacon, Grotius, Pascal, Cromwell, Bossuet, Montesquieu, Jefferson, Napoleon, Pitt, etc. The result would be an Encyclopedia of Error.

Some Reflections on Peace in Our Time (1950)

Journal entry (26 August 1938); later published in The Wartime Journals (1970)
Context: The readiness to blame a dead pilot for an accident is nauseating, but it has been the tendency ever since I can remember. What pilot has not been in positions where he was in danger and where perfect judgment would have advised against going? But when a man is caught in such a position he is judged only by his error and seldom given credit for the times he has extricated himself from worse situations. Worst of all, blame is heaped upon him by other pilots, all of whom have been in parallel situations themselves, but without being caught in them. If one took no chances, one would not fly at all. Safety lies in the judgment of the chances one takes. That judgment, in turn, must rest upon one's outlook on life. Any coward can sit in his home and criticize a pilot for flying into a mountain in fog. But I would rather, by far, die on a mountainside than in bed. Why should we look for his errors when a brave man dies? Unless we can learn from his experience, there is no need to look for weakness. Rather, we should admire the courage and spirit in his life. What kind of man would live where there is no daring? And is life so dear that we should blame men for dying in adventure? Is there a better way to die?

The Kasîdah of Hâjî Abdû El-Yezdî (1870), Note I : Hâjî Abdû, The Man
Context: That creatures endowed with the mere possibility of liberty should not always choose the Good appears natural. But that of the milliards of human beings who have inhabited Earth, not one should have been found invariably to choose Good, proves how insufficient is the solution. Hence no one believes in the existence of the complete man under the present state of things. The Haji rejects all popular and mythical explanation by the Fall of "Adam," the innate depravity of human nature, and the absolute perfection of certain Incarnations, which argues their divinity. He can only wail over the prevalence of evil, assume its foundation to be error, and purpose to abate it by uprooting that Ignorance which bears and feeds it.
His "eschatology," like that of the Soofis generally, is vague and shadowy.

Autobiography (1873)
Context: it might even be questioned if the various causes of deterioration which had been at work in the meanwhile, had not more than counterbalanced the tendencies to improvement. I had learnt from experience that many false opinions may be exchanged for true ones, without in the least altering the habits of mind of which false opinions are the result. The English public, for example, are quite as raw and undiscerning on subjects of political economy since the nation has been converted to free-trade, as they were before; and are still further from having acquired better habits of thought and feeling, or being in any way better fortified against error, on subjects of a more elevated character. For, though they have thrown off certain errors, the general discipline of their minds, intellectually and morally, is not altered. I am now convinced, that no great improvements in the lot of mankind are possible, until a great change takes place in the fundamental constitution of their modes of thought.

Opera Omnia, ser. 1, vol. 2, p. 459 Spcimen de usu observationum in mathesi pura, as quoted by George Pólya, Induction and Analogy in Mathematics Vol. 1, Mathematics and Plausible Reasoning (1954)
Context: It will seem a little paradoxical to ascribe a great importance to observations even in that part of the mathematical sciences which is usually called Pure Mathematics, since the current opinion is that observations are restricted to physical objects that make impression on the senses. As we must refer the numbers to the pure intellect alone, we can hardly understand how observations and quasi-experiments can be of use in investigating the nature of numbers. Yet, in fact, as I shall show here with very good reasons, the properties of the numbers known today have been mostly discovered by observation, and discovered long before their truth has been confirmed by rigid demonstrations. There are many properties of the numbers with which we are well acquainted, but which we are not yet able to prove; only observations have led us to their knowledge. Hence we see that in the theory of numbers, which is still very imperfect, we can place our highest hopes in observations; they will lead us continually to new properties which we shall endeavor to prove afterwards. The kind of knowledge which is supported only by observations and is not yet proved must be carefully distinguished from the truth; it is gained by induction, as we usually say. Yet we have seen cases in which mere induction led to error. Therefore, we should take great care not to accept as true such properties of the numbers which we have discovered by observation and which are supported by induction alone. Indeed, we should use such discovery as an opportunity to investigate more exactly the properties discovered and to prove or disprove them; in both cases we may learn something useful.

Cross of Gold Speech (1896)
Context: This is not a contest between persons. The humblest citizen in all the land, when clad in the armor of a righteous cause, is stronger than all the hosts of error. I come to speak to you in defence of a cause as holy as the cause of liberty—the cause of humanity.

Physics and Philosophy (1958)
Context: The words "position" and "velocity" of an electron... seemed perfectly well defined... and in fact they were clearly defined concepts within the mathematical framework of Newtonian mechanics. But actually they were not well defined, as seen from the relations of uncertainty. One may say that regarding their position in Newtonian mechanics they were well defined, but in their relation to nature, they were not. This shows that we can never know beforehand which limitations will be put on the applicability of certain concepts by the extension of our knowledge into the remote parts of nature, into which we can only penetrate with the most elaborate tools. Therefore, in the process of penetration we are bound sometimes to use our concepts in a way which is not justified and which carries no meaning. Insistence on the postulate of complete logical clarification would make science impossible. We are reminded... of the old wisdom that one who insists on never uttering an error must remain silent.

Aphorism 42
Novum Organum (1620), Book I
Context: The Idols of the Cave are the idols of the individual man. For everyone (besides the errors common to human nature in general) has a cave or den of his own, which refracts and discolors the light of nature, owing either to his own proper and peculiar nature; or to his education and conversation with others; or to the reading of books, and the authority of those whom he esteems and admires; or to the differences of impressions, accordingly as they take place in a mind preoccupied and predisposed or in a mind indifferent and settled; or the like. So that the spirit of man (according as it is meted out to different individuals) is in fact a thing variable and full of perturbation, and governed as it were by chance. Whence it was well observed by Heraclitus that men look for sciences in their own lesser worlds, and not in the greater or common world.

1910s
Context: The aim of science is to seek the simplest explanations of complex facts. We are apt to fall into the error of thinking that the facts are simple because simplicity is the goal of our quest. The guiding motto in the life of every natural philosopher should be, "Seek simplicity and distrust it."

Context: If a captive mind is unaware of being in prison, it is living in error. If it has recognized the fact, even for the tenth of a second, and then quickly forgotten it in order to avoid suffering, it is living in falsehood. Men of the most brilliant intelligence can be born, live and die in error and falsehood. In them, intelligence is neither a good, nor even an asset. The difference between more or less intelligent men is like the difference between criminals condemned to life imprisonment in smaller or larger cells. The intelligent man who is proud of his intelligence is like a condemned man who is proud of his large cell.

Flatland: A Romance of Many Dimensions (1884)
Context: p>Suppose a person of the Fourth Dimension, condescending to visit you, were to say, 'Whenever you open your eyes, you see a Plane (which is of Two Dimensions) and you INFER a Solid (which is of Three); but in reality you also see (though you do not recognize) a Fourth Dimension, which is not colour nor brightness nor anything of the kind, but a true Dimension, although I cannot point out to you its direction, nor can you possibly measure it.' What would you say to such a visitor? Would not you have him locked up? Well, that is my fate: and it is as natural for us Flatlanders to lock up a Square for preaching the Third Dimension, as it is for you Spacelanders to lock up a Cube for preaching the Fourth. Alas, how strong a family likeness runs through blind and persecuting humanity in all Dimensions! Points, Lines, Squares, Cubes, Extra-Cubes — we are all liable to the same errors, all alike the Slaves of our respective Dimensional prejudices, as one of your Spaceland poets has said — 'One touch of Nature makes all worlds akin.' </p

American Communications Association v. Douds, 339 U.S. 382, 442-43 (1950)
Judicial opinions
Context: The priceless heritage of our society is the unrestricted constitutional right of each member to think as he will. Thought control is a copyright of totalitarianism, and we have no claim to it. It is not the function of the government to keep the citizen from falling into error; it is the function of the citizen to keep the government from falling into error. We could justify any censorship only when the censors are better shielded against error than the censored.

Letter to Francis W. Gilmer (1816)
1810s
Context: There is an error into which most of the speculators on government have fallen, and which the well-known state of society of our Indians ought, before now, to have corrected. In their hypothesis of the origin of government, they suppose it to have commenced in the patriarchal or monarchical form. Our Indians are evidently in that state of nature which has passed the association of a single family... The Cherokees, the only tribe I know to be contemplating the establishment of regular laws, magistrates, and government, propose a government of representatives, elected from every town. But of all things, they least think of subjecting themselves to the will of one man.

Introductory Remarks
Thoughts on African Colonization (1832)
Context: Is Error, though unwittingly supported by a host of good men, stronger than Truth? Are Right and Wrong convertible terms, dependant upon popular opinion? Oh no! Then I will go forward in the strength of the Lord of Hosts — in the name of Truth — and under the banner of Right. As it is not by might nor by power, but by the Spirit of God, that great moral changes are effected, I am encouraged to fight valiantly in this good cause, believing that I shall "come off conqueror, and more than conqueror" — yet not I, but Truth and Justice. It is in such a contest that one shall chase a thousand, and two put ten thousand to flight.

Part III : Recantation, Ch. XI Compensation
A Perplexed Philosopher (1892)
Context: The primary error of the advocates of land nationalization is in their confusion of equal rights with joint rights, and in their consequent failure to realize the nature and meaning of economic rent… In truth the right to the use of land is not a joint or common right, but an equal right; the joint or common right is to rent, in the economic sense of the term. Therefore it is not necessary for the state to take land, it is only necessary for it to take rent. This taking by the commonalty of what is of common right, would of itself secure equality in what is of equal right — for since the holding of land could be profitable only to the user, there would be no inducement for any one to hold land that he could not adequately use, and monopolization being ended no one who wanted to use land would have any difficulty in finding it.

Preface
The Screwtape Letters (1942)
Context: There are two equal and opposite errors into which our race can fall about the devils. One is to disbelieve in their existence. The other is to believe, and to feel an excessive and unhealthy interest in them. They themselves are equally pleased by both errors and hail a materialist or a magician with the same delight.

The Cornerstone Speech (1861)
Context: This idea, though not incorporated in the constitution, was the prevailing idea at that time. The constitution, it is true, secured every essential guarantee to the institution while it should last, and hence no argument can be justly urged against the constitutional guarantees thus secured, because of the common sentiment of the day. Those ideas, however, were fundamentally wrong. They rested upon the assumption of the equality of races. This was an error. It was a sandy foundation, and the government built upon it fell when the 'storm came and the wind blew'.

Man and Socialism in Cuba (1965)
Context: Socialism is young and has made errors. Many times revolutionaries lack the knowledge and intellectual courage needed to meet the task of developing the new man with methods different from the conventional ones — and the conventional methods suffer from the influences of the society, which created them.

A New View of Society (1813-1816)
Context: All that is now requisite, previous to withdrawing the last mental bandage by which hitherto the human race has been kept in darkness and misery, is, by calm and patient reasoning to tranquillize the public mind, and thus prevent the evil effects which otherwise might arise from the too sudden prospect of freely enjoying rational liberty of mind. To withdraw that bandage without danger, reason must be judiciously applied to lead men of every sect (for all have been in part abused to reflect that if untold myriads of beings, formed like themselves, have been so grossly deceived as they believe them to have been, what power in nature was there to prevent them from being equally deceived? Such reflections, steadily pursued by those who are anxious to follow the plain and simple path of reason, will soon make it obvious that the inconsistencies which they behold in all other sects out of their own pale, are precisely similar to those which all other sects can readily discover within that pale. It is not, however, to be imagined, that this free and open exposure of the gross errors in which the existing generation has been instructed, should be forthwith palatable to the world; it would be contrary to reason to form any such expectations. Yet, as evil exists, and as man cannot be rational, nor of course happy, until the cause of it shall be removed; the writer, like a physician who feels the deepest interest in the welfare of his patient, has hitherto administered of this unpalatable restorative the smallest quantity which he deemed sufficient for the purpose. He now waits to see the effects which that may produce. Should the application not prove of sufficient strength to remove the mental disorder, he promises that it shall be increased, until sound health to the public mind be firmly and permanently established.

Woman in the Nineteenth Century (1845)
Context: Woman, self-centred, would never be absorbed by any relation it would be only an experience to her as to man. It is a vulgar error that love, a love, to Woman is her whole existence; she also is born for Truth and Love in their universal energy.

Source: 1920s, Prejudices, Third Series (1922), Ch. 3 "Footnote on Criticism", pp. 85-104
Context: Truth, indeed, is something that is believed in completely only by persons who have never tried personally to pursue it to its fastness and grab it by the tail. It is the adoration of second-rate men — men who always receive it as second-hand. Pedagogues believe in immutable truths and spend their lives trying to determine them and propagate them; the intellectual progress of man consists largely of a concerted effort to block and destroy their enterprise. Nine times out of ten, in the arts as in life, there is actually no truth to be discovered; there is only error to be exposed. In whole departments of human inquiry it seems to me quite unlikely that the truth ever will be discovered. Nevertheless, the rubber-stamp thinking of the world always makes the assumption that the exposure of an error is identical with the discovery of truth — that error and truth are simply opposites. They are nothing of the sort. What the world turns to, when it has been cured of one error, is usually simply another error, and maybe one worse than the first one. This is the whole history of the intellect in brief. The average man of today does not believe in precisely the same imbecilities that the Greek of the Fourth Century before Christ believed in, but the things that he does believe in are often quite as idiotic.
Perhaps this statement is a bit too sweeping. There is, year by year, a gradual accumulation of what may be called, provisionally, truths — there is a slow accretion of ideas that somehow manage to meet all practicable human tests, and so survive. But even so, it is risky to call them absolute truths. All that one may safely say of them is that no one, as yet, has demonstrated that they are errors. Soon or late, if experience teaches us anything, they are likely to succumb too. The profoundest truths of the Middle Ages are now laughed at by schoolboys. The profoundest truths of democracy will be laughed at, a few centuries hence, even by school-teachers.

Introduction : The Reason for the Examination
A Perplexed Philosopher (1892)
Context: The respect for authority, the presumption in favor of those who have won intellectual reputation, is within reasonable limits, both prudent and becoming. But it should not be carried too far, and there are some things especially as to which it behooves us all to use our own judgment and to maintain free minds. For not only does the history of the world show that undue deference to authority has been the potent agency through which errors have been enthroned and superstitions perpetuated, but there are regions of thought in which the largest powers and the greatest acquirements cannot guard against aberrations or assure deeper insight. One may stand on a box and look over the heads of his fellows, but he no better sees the stars. The telescope and the microscope reveal depths which to the unassisted vision are closed. Yet not merely do they bring us no nearer to the cause of suns and animal-cula, but in looking through them the observer must shut his eyes to what lies about him. That intension is at the expense of extension is seen in the mental as in the physical sphere. A man of special learning may be a fool as to common relations. And that he who passes for an intellectual prince may be a moral pauper there are examples enough to show.

Judicial opinions

Source: Guide for the Perplexed (c. 1190), Part III, Ch.23
Context: The words of God are justified, as I will show, by the fact that Job abandoned his first very erroneous opinion, and himself proved that it was an error. It is the opinion which suggests itself as plausible at first thought, especially in the minds of those who meet with mishap, well knowing that they have not merited them through sins. This is admitted by all, and therefore this opinion was assigned to Job. But he is represented to hold this view only so long as he was without wisdom, and knew God only by tradition, in the same manner as religious people generally know Him. As soon as he had acquired a true knowledge of God, he confessed that there is undoubtedly true felicity in the knowledge of God; it is attained by all who acquire that knowledge, and no earthly trouble can disturb it. So long as Job's knowledge of God was based on tradition and communication, and not on research, he believed that such imaginary good as is possessed in health, riches, and children, was the utmost that men can attain; this was the reason why he was in perplexity, and why he uttered the... opinions, and this is also the meaning of his words: "I have heard of thee by the hearing of the ear; but now mine eye seeth thee. Wherefore I abhor myself, and repent because of dust and ashes" (xlii. 5, 6); that is to say, he abhorred all that he had desired before, and that he was sorry that he had been in dust and ashes; comp. "and he sat down among the ashes" (ii. 8) On account of this last utterance, which implies true perception, it is said afterwards in reference to him, "for you have not spoken of me the thing that is right, as my servant Job hath."

Part IV, Chapter 6
Anna Karenina (1875–1877; 1878)
Context: The new commission for the inquiry into the condition of the native tribes in all its branches had been formed and dispatched to its destination with an unusual speed and energy inspired by Alexey Alexandrovitch. Within three months a report was presented. The condition of the native tribes was investigated in its political, administrative, economic, ethnographic, material, and religious aspects. To all these questions there were answers admirably stated, and answers admitting no shade of doubt, since they were not a product of human thought, always liable to error, but were all the product of official activity. The answers were all based on official data furnished by governors and heads of churches, and founded on the reports of district magistrates and ecclesiastical superintendents, founded in their turn on the reports of parochial overseers and parish priests; and so all of these answers were unhesitating and certain. All such questions as, for instance, of the cause of failure of crops, of the adherence of certain tribes to their ancient beliefs, etc.—questions which, but for the convenient intervention of the official machine, are not, and cannot be solved for ages—received full, unhesitating solution.

The Kasîdah of Hâjî Abdû El-Yezdî (1870), Note I : Hâjî Abdû, The Man
Context: He looks with impartial eye upon the endless variety of systems, maintained with equal confidence and self-sufficiency, by men of equal ability and honesty. He is weary of wandering over the world, and of finding every petty race wedded to its own opinions; claiming the monopoly of Truth; holding all others to be in error, and raising disputes whose violence, acerbity and virulence are in inverse ratio to the importance of the disputed matter. A peculiarly active and acute observation taught him that many of these jarring families, especially those of the same blood, are par in the intellectual processes of perception and reflection; that in the business of the visible working world they are confessedly by no means superior to one another; whereas in abstruse matters of mere Faith, not admitting direct and sensual evidence, one in a hundred will claim to be right, and immodestly charge the other ninety-nine with being wrong.
Thus he seeks to discover a system which will prove them all right, and all wrong; which will reconcile their differences; will unite past creeds; will account for the present, and will anticipate the future with a continuous and uninterrupted development; this, too, by a process, not negative and distinctive, but, on the contrary, intensely positive and constructive. I am not called upon to sit in the seat of judgment; but I may say that it would be singular if the attempt succeeded. Such a system would be all-comprehensive, because not limited by space, time, or race; its principle would be extensive as Matter itself, and, consequently, eternal. Meanwhile he satisfies himself, — the main point.

Original in French from Œuvres de Pasteur, Volume 7 (1939), Masson et cie, p. 539: Mon opinion, mieux encore, ma conviction, c'est que, dans l'état actuel de la science, comme vous dites avec raison, la génération spontanée est une chimère, et il vous serait impossible de me contredire, car mes expériences sont toutes debout, et toutes prouvent que la génération spontanée est une chimère
The Life of Pasteur (1902)
Context: You say that, in the present state of science, it is wiser to have no opinion: well, I have an opinion, not a sentimental one, but a rational one, having acquired a right to it by twenty years of assiduous labour, and it would be wise in every impartial mind to share it. My opinion — nay more, my conviction — is that, in the present state of science, as you rightly say, spontaneous generation is a chimera; and it would be impossible for you to contradict me, for my experiments all stand forth to prove that spontaneous generation is a chimera. What is then your judgment on my experiments? Have I not a hundred times placed organic matter in contact with pure air in the best conditions for it to produce life spontaneously? Have I not practised on these organic materia which are most favourable, according to all accounts, to the genesis of spontaneity, such as blood, urine, and grape juice? How is it that you do not see the essential difference between my opponents and myself? Not only have I contradicted, proof in hand, every one of their assertions, while they have never dared to seriously contradict one of mine, but, for them, every cause of error benefits their opinion. For me, affirming as I do that there are no spontaneous fermentations, I am bound to eliminate every cause of error, every perturbing influence, I can maintain my results only by means of most irreproachable experiments; their opinions, on the contrary, profit by every insufficient experiment and that is where they find their support.

Source: Reason: The Only Oracle Of Man (1784), Ch. XIII Section II - Of The Importance of the Exercise of Reason, and Practice of Morality, in order to the Happiness of Mankind
Context: An unjust composition never fails to contain error and falsehood. Therefore an unjust connection of ideas is not derived from nature, but from the imperfect composition of man. Misconnection of ideas is the same as misjudging, and has no positive existence, being merely a creature of the imagination; but nature and truth are real and uniform; and the rational mind by reasoning, discerns the uniformity, and is thereby enabled to make a just composition of ideas, which will stand the test of truth. But the fantastical illuminations of the credulous and superstitious part of mankind, proceed from weakness, and as far as they take place in the world subvert the religion of REASON, NATURE and TRUTH.

"Of Love" as translated in The Infinite in Giordano Bruno : With a Translation of His Dialogue, Concerning the Cause, Principle, and One (1978) by Sidney Thomas Greenburg, p. 89
Variant translation:
Cause, Principle and One, the Sempiterne,
On whom all being, motion, life, depend.
From whom, in length, breadth, depth, their paths extend
As far as heaven, earth, hell their faces turn :
With sense, with mind, with reason, I discern
That not, rule, reckoning, may not comprehend
That power and bulk and multitude which tend
Beyond all lower, middle, and superne. <p> Blind error, ruthless time, ungentle doom,
Deaf envy, villain madness, zeal unwise,
Hard heart, unholy craft, bold deeds begun,
Shall never fill for one the air with gloom,
Or ever thrust a veil before these eyes,
Or ever hide from me my glorious sun.
As quoted in "Giordano Bruno" by Thomas Davidson, The Index Vol. VI. No. 36 (4 March 1886), p. 429

With sense, with reason, with mind, I discern,

Which exceeds whatever is inferior, middle, and highest;
Blind error, avaricious time, adverse fortune,
Deaf envy, vile madness, jealous iniquity,
Crude heart, perverse spirit, insane audacity,
Will not be sufficient to obscure the air for me,
Will not place the veil before my eyes,
Will never bring it about that I shall not
Contemplate my beautiful Sun.

Dream Days (1898), The Reluctant Dragon
Context: No doubt you would deeply regret any error you might make in the hurry of the moment; but you wouldn't regret it half as much as I should! However, I suppose we've got to trust somebody, as we go through life, and your plan seems, on the whole, as good a one as any.

1870s, Eighth State of the Union Address (1876)
Context: It was my fortune, or misfortune, to be called to the office of Chief Executive without any previous political training. From the age of 17 I had never even witnessed the excitement attending a Presidential campaign but twice antecedent to my own candidacy, and at but one of them was I eligible as a voter.
Under such circumstances it is but reasonable to suppose that errors of judgment must have occurred. Even had they not, differences of opinion between the Executive, bound by an oath to the strict performance of his duties, and writers and debaters must have arisen. It is not necessarily evidence of blunder on the part of the Executive because there are these differences of views. Mistakes have been made, as all can see and I admit...

An Humble, Earnest and Affectionate Address to the Clergy (1761)
Context: Show me a man whose heart has no desire, or prayer in it, but to love God with his whole soul and spirit, and his neighbor as himself, and then you have shown me the man who knows Christ, and is known of him; the best and wisest man in the world, in whom the first paradisaical wisdom and goodness are come to life. Not a single precept in the gospel, but is the precept of his own heart, and the joy of that new-born heavenly love which is the life and light of his soul. In this man, all that came from the old serpent is trod under his feet, not a spark of self, of pride, of wrath, of envy, of covetousness, or worldly wisdom, can have the least abode in him, because that love, which fulfilleth the whole Law and the prophets, that love which is God and Christ, both in angels and men, is the love that gives birth, and life, and growth to everything that is either thought, or word, or action in him. And if he has no share or part with foolish errors, cannot be tossed about with every wind of doctrine, it is because, to be always governed by this love, is the same thing as to be always taught of God.
On the other hand, show me a scholar as full of learning, as the Vatican is of books, and he will be just as likely to give all that he has for the gospel-pearl, as he would be, if he was as rich as Croesus. Let no one here imagine, that I am writing against all human literature, arts and sciences, or that I wish the world to be without them. I am no more an enemy to them, than to the common useful labors of life. It is literal learning, verbal contention, and critical strife about the things of God, that I charge with folly and mischief to religion. And in this, I have all learned Christendom, both popish and Protestant on my side. For they both agree in charging each other with a bad and false gospel-state, because of that which their learning, logic, and criticism do for them. Say not then, that it is only the illiterate enthusiast that condemns human learning in the gospel kingdom of God. For when he condemns the blindness and mischief of popish logic and criticism, he has all the learned Protestant world with him; and when he lays the same charge to Protestant learning, he has a much larger kingdom of popish great scholars, logically and learnedly affirming the same thing. So that the private person, charging human learning with so much mischief to the church, is so far from being led by enthusiasm, that he is led by all the church-learning that is in the world.
