H.L. Mencken Quotes
page 2

Henry Louis Mencken was an American journalist, satirist, cultural critic and scholar of American English. Known as the "Sage of Baltimore", he is regarded as one of the most influential American writers and prose stylists of the first half of the twentieth century. He commented widely on the social scene, literature, music, prominent politicians and contemporary movements. His satirical reporting on the Scopes trial, which he dubbed the "Monkey Trial", also gained him attention.

As a scholar, Mencken is known for The American Language, a multi-volume study of how the English language is spoken in the United States. As an admirer of the German philosopher Friedrich Nietzsche, he was a detractor of religion, populism and representative democracy, which he believed to be a system in which inferior men dominated their superiors. Mencken was a supporter of scientific progress, skeptical of economic theories and critical of osteopathic and chiropractic medicine.

Mencken opposed American entry into World War I and World War II. His diary indicates that he was a racist and anti-semite, and privately used coarse language and slurs to describe various ethnic and racial groups . Mencken also at times seemed to show a genuine enthusiasm for militarism, though never in its American form. "War is a good thing," he once wrote, "because it is honest, it admits the central fact of human nature… A nation too long at peace becomes a sort of gigantic old maid."

Mencken's longtime home in the Union Square neighborhood of West Baltimore was turned into a city museum, the H. L. Mencken House. His papers were distributed among various city and university libraries, with the largest collection held in the Mencken Room at the central branch of Baltimore's Enoch Pratt Free Library.

H.L. Mencken Quotes

“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.”

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.

“He has a right to argue for them as eloquently as he can, in season and out of season. He has a right to teach them to his children. But certainly he has no right to be protected against the free criticism of those who do not hold them. . . . They are free to shoot back. But they can't disarm their enemy.”

"Aftermath" in the Baltimore Evening Sun http://www.positiveatheism.org/hist/menck05.htm#SCOPESD (14 September 1925)
1920s
Context: Once more, alas, I find myself unable to follow the best Liberal thought. What the World's contention amounts to, at bottom, is simply the doctrine that a man engaged in combat with superstition should be very polite to superstition. This, I fear, is nonsense. The way to deal with superstition is not to be polite to it, but to tackle it with all arms, and so rout it, cripple it, and make it forever infamous and ridiculous. Is it, perchance, cherished by persons who should know better? Then their folly should be brought out into the light of day, and exhibited there in all its hideousness until they flee from it, hiding their heads in shame.
True enough, even a superstitious man has certain inalienable rights. He has a right to harbor and indulge his imbecilities as long as he pleases, provided only he does not try to inflict them upon other men by force. He has a right to argue for them as eloquently as he can, in season and out of season. He has a right to teach them to his children. But certainly he has no right to be protected against the free criticism of those who do not hold them.... They are free to shoot back. But they can't disarm their enemy.
The meaning of religious freedom, I fear, is sometimes greatly misapprehended. It is taken to be a sort of immunity, not merely from governmental control but also from public opinion. A dunderhead gets himself a long-tailed coat, rises behind the sacred desk, and emits such bilge as would gag a Hottentot. Is it to pass unchallenged? If so, then what we have is not religious freedom at all, but the most intolerable and outrageous variety of religious despotism. Any fool, once he is admitted to holy orders, becomes infallible. Any half-wit, by the simple device of ascribing his delusions to revelation, takes on an authority that is denied to all the rest of us.... What should be a civilized man's attitude toward such superstitions? It seems to me that the only attitude possible to him is one of contempt. If he admits that they have any intellectual dignity whatever, he admits that he himself has none. If he pretends to a respect for those who believe in them, he pretends falsely, and sinks almost to their level. When he is challenged he must answer honestly, regardless of tender feelings.

“The most curious social convention of the great age in which we live is the one to the effect that religious opinions should be respected. Its evil effects must be plain enough to everyone.”

The American Mercury (March, 1930); first printed, in part, in the Baltimore Evening Sun (9 December 1929)
1920s
Context: The most curious social convention of the great age in which we live is the one to the effect that religious opinions should be respected. Its evil effects must be plain enough to everyone. All it accomplishes is (a) to throw a veil of sanctity about ideas that violate every intellectual decency, and (b) to make every theologian a sort of chartered libertine. No doubt it is mainly to blame for the appalling slowness with which really sound notions make their way in the world. The minute a new one is launched, in whatever field, some imbecile of a theologian is certain to fall upon it, seeking to put it down. The most effective way to defend it, of course, would be to fall upon the theologian, for the only really workable defense, in polemics as in war, is a vigorous offensive. But the convention that I have mentioned frowns upon that device as indecent, and so theologians continue their assault upon sense without much resistance, and the enlightenment is unpleasantly delayed.
There is, in fact, nothing about religious opinions that entitles them to any more respect than other opinions get. On the contrary, they tend to be noticeably silly. If you doubt it, then ask any pious fellow of your acquaintance to put what he believes into the form of an affidavit, and see how it reads…. “I, John Doe, being duly sworn, do say that I believe that, at death, I shall turn into a vertebrate without substance, having neither weight, extent nor mass, but with all the intellectual powers and bodily sensations of an ordinary mammal;... and that, for the high crime and misdemeanor of having kissed my sister-in-law behind the door, with evil intent, I shall be boiled in molten sulphur for one billion calendar years.” Or, “I, Mary Roe, having the fear of Hell before me, do solemnly affirm and declare that I believe it was right, just, lawful and decent for the Lord God Jehovah, seeing certain little children of Beth-el laugh at Elisha’s bald head, to send a she-bear from the wood, and to instruct, incite, induce and command it to tear forty-two of them to pieces.” Or, “I, the Right Rev. _____ _________, Bishop of _________, D. D., LL. D., do honestly, faithfully and on my honor as a man and a priest, declare that I believe that Jonah swallowed the whale,” or vice versa, as the case may be. No, there is nothing notably dignified about religious ideas. They run, rather, to a peculiarly puerile and tedious kind of nonsense. At their best, they are borrowed from metaphysicians, which is to say, from men who devote their lives to proving that twice two is not always or necessarily four. At their worst, they smell of spiritualism and fortune telling. Nor is there any visible virtue in the men who merchant them professionally. Few theologians know anything that is worth knowing, even about theology, and not many of them are honest. One may forgive a Communist or a Single Taxer on the ground that there is something the matter with his ductless glands, and that a Winter in the south of France would relieve him. But the average theologian is a hearty, red-faced, well-fed fellow with no discernible excuse in pathology. He disseminates his blather, not innocently, like a philosopher, but maliciously, like a politician. In a well-organized world he would be on the stone-pile. But in the world as it exists we are asked to listen to him, not only politely, but even reverently, and with our mouths open.

“No matter how stupid they were, they could not be more stupid than the average legislator under the present system.”

329
1940s–present, Minority Report : H.L. Mencken's Notebooks (1956)
Context: My old suggestion that public offices be filled by drawing lots, as a jury box is filled, was probably more intelligent than I suspected. It has been criticized on the ground that selecting a man at random would probably produce some extremely bad State governors. [... ] But I incline to believe that it would be best to choose members of the Legislature quite at random. No matter how stupid they were, they could not be more stupid than the average legislator under the present system. Certainly, they'd be measurably more honest, taking one with another. Finally, there would be the great advantage that all of them had got their jobs unwillingly, and were eager, not to spin out their sessions endlessly, but to get home as soon as possible.

“I confess, for my part, that it greatly delights me. I enjoy democracy immensely. It is incomparably idiotic, and hence incomparably amusing. Does it exalt dunderheads, cowards, trimmers, frauds, cads? Then the pain of seeing them go up is balanced and obliterated by the joy of seeing them come down.”

1920s, Notes on Democracy (1926)
Context: Democracy always seems bent upon killing the thing it theoretically loves. I have rehearsed some of its operations against liberty, the very cornerstone of its political metaphysic. It not only wars upon the thing itself; it even wars upon mere academic advocacy of it. I offer the spectacle of Americans jailed for reading the Bill of Rights as perhaps the most gaudily humorous ever witnessed in the modern world. Try to imagine monarchy jailing subjects for maintaining the divine right of Kings! Or Christianity damning a believer for arguing that Jesus Christ was the Son of God! This last, perhaps, has been done: anything is possible in that direction. But under democracy the remotest and most fantastic possibility is a common place of every day. All the axioms resolve themselves into thundering paradoxes, many amounting to downright contradictions in terms. The mob is competent to rule the rest of us—but it must be rigorously policed itself. There is a government, not of men, but of laws—but men are set upon benches to decide finally what the law is and may be. The highest function of the citizen is to serve the state—but the first assumption that meets him, when he essays to discharge it, is an assumption of his disingenuousness and dishonour. Is that assumption commonly sound? Then the farce only grows the more glorious.
I confess, for my part, that it greatly delights me. I enjoy democracy immensely. It is incomparably idiotic, and hence incomparably amusing. Does it exalt dunderheads, cowards, trimmers, frauds, cads? Then the pain of seeing them go up is balanced and obliterated by the joy of seeing them come down. Is it inordinately wasteful, extravagant, dishonest? Then so is every other form of government: all alike are enemies to laborious and virtuous men. Is rascality at the very heart of it? Well, we have borne that rascality since 1776, and continue to survive. In the long run, it may turn out that rascality is necessary to human government, and even to civilization itself—that civilization, at bottom, is nothing but a colossal swindle. I do not know: I report only that when the suckers are running well the spectacle is infinitely exhilarating. But I am, it may be, a somewhat malicious man: my sympathies, when it comes to suckers, tend to be coy. What I can't make out is how any man can believe in democracy who feels for and with them, and is pained when they are debauched and made a show of. How can any man be a democrat who is sincerely a democrat?

“I am, in fact, the complete anti-Messiah, and detest converts almost as much as I detest missionaries. My writings, such as they are, have had only one purpose: to attain for H. L. Mencken that feeling of tension relieved and function achieved which a cow enjoys on giving milk.”

"For the Defense Written for the Associated Press, for use in my obituary" (20 November 1940)
1940s–present
Context: Having lived all my life in a country swarming with messiahs, I have been mistaken, perhaps quite naturally, for one myself, especially by the others. It would be hard to imagine anything more preposterous. I am, in fact, the complete anti-Messiah, and detest converts almost as much as I detest missionaries. My writings, such as they are, have had only one purpose: to attain for H. L. Mencken that feeling of tension relieved and function achieved which a cow enjoys on giving milk. Further than that, I have had no interest in the matter whatsoever. It has never given me any satisfaction to encounter one who said my notions had pleased him. My preference has always been for people with notions of their own. I have believed all my life in free thought and free speech—up to and including the utmost limits of the endurable.

“For what democracy needs most of all is a party that will separate the good that is in it theoretically from the evils that beset it practically, and then try to erect that good into a workable system. What it needs beyond everything is a party of liberty.”

1920s, Notes on Democracy (1926)
Context: For what democracy needs most of all is a party that will separate the good that is in it theoretically from the evils that beset it practically, and then try to erect that good into a workable system. What it needs beyond everything is a party of liberty. It produces, true enough, occasional libertarians, just as despotism produces occasional regicides, but it treats them in the same drum-head way. It will never have a party of them until it invents and installs a genuine aristocracy, to breed them and secure them.

“I do not object to being denounced, but I can't abide being schoolmastered, especially by men I regard as imbeciles.”

Source: 1920s, Prejudices, Third Series (1922), Ch. 3 "Footnote on Criticism", pp. 85-104
Context: Upon the low value of "constructive" criticism I can offer testimony out of my own experience. My books have been commonly reviewed at length, and many critics have devoted themselves to pointing out what they conceive to be my errors, both of fact and of taste. Well, I cannot recall a case in which any suggestion offered by a "constructive" critic has helped me in the slightest, or even actively interested me. Every such wet-nurse of letters has sought fatuously to make me write in a way differing from that in which the Lord God Almighty, in His infinite wisdom, impels me to write — that is, to make me write stuff which, coming from me, would be as false as an appearance of decency in a Congressman. All the benefits I have ever got from the critics of my work have come from the destructive variety. A hearty slating always does me good, particularly if it be well written. It begins by enlisting my professional respect; it ends by making me examine my ideas coldly in the privacy of my chamber. Not, of course, that I usually revise them, but I at least examine them. If I decide to hold fast to them, they are all the dearer to me thereafter, and I expound them with a new passion and plausibility. If, on the contrary, I discern holes in them, I shelve them in a pianissimo manner, and set about hatching new ones to take their place. But "constructive" criticism irritates me. I do not object to being denounced, but I can't abide being schoolmastered, especially by men I regard as imbeciles.

“The final test of truth is ridicule. Very few dogmas have ever faced it and survived.”

"On Truth" in Damn! A Book of Calumny (1918), p. 53
1910s
Context: The final test of truth is ridicule. Very few dogmas have ever faced it and survived. Huxley laughed the devils out of the Gadarene swine. Not the laws of the United States but the mother-in-law joke brought the Mormons to surrender. Not the horror of it but the absurdity of it killed the doctrine of infant damnation. But the razor edge of ridicule is turned by the tough hide of truth. How loudly the barber-surgeons laughed at Huxley—and how vainly! What clown ever brought down the house like Galileo? Or Columbus? Or Darwin?... They are laughing at Nietzsche yet...

“That pathology is grounded upon the doctrine that all human ills are caused by the pressure of misplaced vertebra upon the nerves which come out of the spinal cord—in other words, that every disease is the result of a pinch. This, plainly enough, is buncombe.

This, obviously, is buncombe doubly damned”

"Chiropractic" in Baltimore Evening Sun http://www.chirobase.org/12Hx/mencken.html (December 1924)
1920s
Context: This preposterous quackery flourishes lushly in the back reaches of the Republic, and begins to conquer the less civilized folk of the big cities. As the oldtime family doctor dies out in the country towns, with no competent successor willing to take over his dismal business, he is followed by some hearty blacksmith or ice-wagon driver, turned into a chiropractor in six months, often by correspondence. In Los Angeles the Damned there are probably more chiropractors than actual physicians, and they are far more generally esteemed. Proceeding from the Ambassador Hotel to the heart of the town, along Wilshire boulevard, one passes scores of their gaudy signs; there are even many chiropractic "hospitals." The morons who pour in from the prairies and deserts, most of them ailing, patronize these "hospitals" copiously, and give to the chiropractic pathology the same high respect that they accord to the theology of the town sorcerers. That pathology is grounded upon the doctrine that all human ills are caused by the pressure of misplaced vertebra upon the nerves which come out of the spinal cord—in other words, that every disease is the result of a pinch. This, plainly enough, is buncombe. The chiropractic therapeutics rest upon the doctrine that the way to get rid of such pinches is to climb upon a table and submit to a heroic pummeling by a retired piano-mover.

“His technical equipment consists simply of an armamentarium of deceits”

On elected politicians
1920s, Notes on Democracy (1926)
Context: Ostensibly he is an altruist devoted whole-heartedly to the service of his fellow-men, and so abjectly public-spirited that his private interest is nothing to him. Actually, he is a sturdy rogue whose principal, and often sole aim in life is to butter his parsnips. His technical equipment consists simply of an armamentarium of deceits. It is his business to get and hold his job at all costs. If he can hold it by lying he will hold it by lying. if lying peters out he will try and hold it by embracing new truths. His ear is ever close to the ground.

“It is the natural tendency of the ignorant to believe what is not true. In order to overcome that tendency it is not sufficient to exhibit the true; it is also necessary to expose and denounce the false.”

The American Mercury (May 1926)
1920s
Context: It is the natural tendency of the ignorant to believe what is not true. In order to overcome that tendency it is not sufficient to exhibit the true; it is also necessary to expose and denounce the false. To admit that the false has any standing in court, that it ought to be handled gently because millions of morons cherish it and thousands of quacks make their livings propagating it—to admit this, as the more fatuous of the reconcilers of science and religion inevitably do, is to abandon a just cause to its enemies, cravenly and without excuse. It is, of course, quite true that there is a region in which science and religion do not conflict. That is the region of the unknowable.

“The Bryan I shall remember is the Bryan of his last weeks on earth -- broken, furious, and infinitely pathetic.”

"Bryan" in Baltimore Evening Sun http://www.positiveatheism.org/hist/menck05.htm#SCOPESC (27 July 1925)
1920s
Context: It is the national custom to sentimentalize the dead, as it is to sentimentalize men about to be hanged. Perhaps I fall into that weakness here. The Bryan I shall remember is the Bryan of his last weeks on earth -- broken, furious, and infinitely pathetic. It was impossible to meet his hatred with hatred to match it. He was winning a battle that would make him forever infamous wherever enlightened men remembered it and him. Even his old enemy, Darrow, was gentle with him at the end. That cross-examination might have been ten times as devastating. It was plain to everyone that the old Berseker Bryan was gone -- that all that remained of him was a pair of glaring and horrible eyes.
But what of his life? Did he accomplish any useful thing? Was he, in his day, of any dignity as a man, and of any value to his fellow-men? I doubt it. Bryan, at his best, was simply a magnificent job-seeker. The issues that he bawled about usually meant nothing to him. He was ready to abandon them whenever he could make votes by doing so, and to take up new ones at a moment's notice. For years he evaded Prohibition as dangerous; then he embraced it as profitable. At the Democratic National Convention last year he was on both sides, and distrusted by both. In his last great battle there was only a baleful and ridiculous malignancy. If he was pathetic, he was also disgusting.
Bryan was a vulgar and common man, a cad undiluted. He was ignorant, bigoted, self-seeking, blatant and dishonest. His career brought him into contact with the first men of his time; he preferred the company of rustic ignoramuses. It was hard to believe, watching him at Dayton, that he had traveled, that he had been received in civilized societies, that he had been a high officer of state. He seemed only a poor clod like those around him, deluded by a childish theology, full of an almost pathological hatred of all learning, all human dignity, all beauty, all fine and noble things. He was a peasant come home to the dung-pile. Imagine a gentleman, and you have imagined everything that he was not.

“Thus the ideal of democracy is reached at last: it has become a psychic impossibility for a gentleman to hold office under the Federal Union, save by a combination of miracles that must tax the resourcefulness even of God. The fact has been rammed home by a constitutional amendment: every office-holder, when he takes oath to support the Constitution, must swear on his honour that, summoned to the death-bed of his grandmother, he will not take the old lady a bottle of wine.”

1920s, Notes on Democracy (1926)
Context: Thus the ideal of democracy is reached at last: it has become a psychic impossibility for a gentleman to hold office under the Federal Union, save by a combination of miracles that must tax the resourcefulness even of God. The fact has been rammed home by a constitutional amendment: every office-holder, when he takes oath to support the Constitution, must swear on his honour that, summoned to the death-bed of his grandmother, he will not take the old lady a bottle of wine. He may say so and do it, which makes him a liar, or he may say so and not do it, which makes him a pig. But despite that grim dilemma there are still idealists, chiefly professional Liberals, who argue that it is the duty of a gentleman to go into politics—that there is a way out of the quagmire in that direction. The remedy, it seems to me, is quite as absurd as all the other sure cures that Liberals advocate. When they argue for it, they simply argue, in words but little changed, that the remedy for prostitution is to fill the bawdyhouses with virgins. My impression is that this last device would accomplish very little: either the virgins would leap out of the windows, or they would cease to be virgins.

“In other words, government is a broker in pillage, and every election is sort of an advance auction sale of stolen goods.”

As quoted in Charting the Candidates '72 (1972) by Ronald Van Doren, p. 7
1940s–present
Context: The state — or, to make the matter more concrete, the government — consists of a gang of men exactly like you and me. They have, taking one with another, no special talent for the business of government; they have only a talent for getting and holding office. Their principal device to that end is to search out groups who pant and pine for something they can't get and to promise to give it to them. Nine times out of ten that promise is worth nothing. The tenth time is made good by looting A to satisfy B. In other words, government is a broker in pillage, and every election is sort of an advance auction sale of stolen goods.

“The great artists of the world are never Puritans, and seldom even ordinarily respectable.”

Context: The great artists of the world are never Puritans, and seldom even ordinarily respectable. No virtuous man — that is, virtuous in the Y. M. C. A. sense — has ever painted a picture worth looking at, or written a symphony worth hearing, or a book worth reading.
