The Abolition of Work (1985)
Context: These experts who offer to do our thinking for us rarely share their conclusions about work, for all its saliency in the lives of all of us. Among themselves they quibble over the details. Unions and management agree that we ought to sell the time of our lives in exchange for survival, although they haggle over the price. Marxists think we should be bossed by bureaucrats. Libertarians think we should be bossed by businessmen. Feminists don't care which form bossing takes so long as the bosses are women. Clearly these ideology-mongers have serious differences over how to divvy up the spoils of power. Just as clearly, none of them have any objection to power as such and all of them want to keep us working.
You may be wondering if I'm joking or serious. I'm joking and serious. To be ludic is not to be ludicrous. Play doesn't have to be frivolous, although frivolity isn't triviality: very often we ought to take frivolity seriously. I'd like life to be a game — but a game with high stakes. I want to play for keeps.

“I am a bard; I will not disclose secrets to slaves;
I am a guide: I am expert in contests.”
Book of Taliesin (c. 1275?), The First Address of Taliesin
Context: I am a bard; I will not disclose secrets to slaves;
I am a guide: I am expert in contests.
If he would sow, he would plough; he would plough, he would not reap.
If a brother among brothers,
Didactic Bards with swelling breasts will arise
Who will meet around mead-vessels,
And sing wrong poetry
And seek rewards that will not be,
Without law, without regulation, without gifts.
And afterwards will become angry.

No. 29
The Federalist Papers (1787–1788)
Context: A tolerable expertness in military movements is a business that requires time and practice. It is not a day, or even a week, that will suffice for the attainment of it. To oblige the great body of the yeomanry, and of the other classes of the citizens, to be under arms for the purpose of going through military exercises and evolutions, as often as might be necessary to acquire the degree of perfection which would entitle them to the character of a well-regulated militia, would be a real grievance to the people, and a serious public inconvenience and loss. It would form an annual deduction from the productive labor of the country, to an amount which, calculating upon the present numbers of the people, would not fall far short of the whole expense of the civil establishments of all the States. To attempt a thing which would abridge the mass of labor and industry to so considerable an extent, would be unwise: and the experiment, if made, could not succeed, because it would not long be endured. Little more can reasonably be aimed at, with respect to the people at large, than to have them properly armed and equipped; and in order to see that this be not neglected, it will be necessary to assemble them once or twice in the course of a year.

The Unsettling of America : Culture & Agriculture (1996), p. 62.
Context: Once plants and animals were raised together on the same farm — which therefore neither produced unmanageable surpluses of manure, to be wasted and to pollute the water supply, nor depended on such quantities of commercial fertilizer. The genius of America farm experts is very well demonstrated here: they can take a solution and divide it neatly into two problems.

1990s, CNN interview (1999)
Context: My vision for this book and the others in the series is to let people know what kind of commanders we have. You don't pick generals off park benches. … They are experts at what they do and lot of thinking goes into it. And I want to get across to people the intellectual dimension of command, to let people know that it's hard to be a general. And the people we have with general stars on their shoulders are pretty smart and pretty good guys.

Letter to Robert Bulwer-Lytton, 1st Earl of Lytton (15 June 1877), as quoted in The Oxford Dictionary of Quotations (1999) Elizabeth M. Knowles, p. 642; this has also been published without the word "insipid".
1870s
Context: No lesson seems to be so deeply inculcated by the experience of life as that you should never trust experts. If you believe doctors, nothing is wholesome: if you believe the theologians, nothing is innocent: if you believe the soldiers, nothing is safe. They all require their strong wine diluted by a very large admixture of insipid common sense.

One Human Minute (1986)
Context: The book does not contain “everything about the human being,” because that is impossible. The largest libraries in the world do not contain “everything.” The quantity of anthropological data discovered by scientists now exceeds any individual’s ability to assimilate it. The division of labor, including intellectual labor, begun thirty thousand years ago in the Paleolithic, has become an irreversible phenomenon, and there is nothing that can be done about it. Like it or not, we have placed our destiny in the hands of the experts. A politician is, after all, a kind of expert, if self-styled. Even the fact that competent experts must serve under politicians of mediocre intelligence and little foresight is a problem that we are stuck with, because the experts themselves cannot agree on any major world issue. A logocracy of quarreling experts might be no better than the rule of the mediocrities to which we are subject. The declining intellectual quality of political leadership is the result of the growing complexity of the world. Since no one, be he endowed with the highest wisdom, can grasp it in its entirety, it is those who are least bothered by this who strive for power.

"Clinical Notes" in The American Mercury (January 1924), p. 75; also in Prejudices, Fourth Series (1924)
1920s
Context: Critical note.—Of a piece with the absurd pedagogical demand for so-called constructive criticism is the doctrine that an iconoclast is a hollow and evil fellow unless he can prove his case. Why, indeed, should he prove it? Is he judge, jury, prosecuting officer, hangman? He proves enough, indeed, when he proves by his blasphemy that this or that idol is defectively convincing—that at least one visitor to the shrine is left full of doubts. The fact is enormously significant; it indicates that instinct has somehow risen superior to the shallowness of logic, the refuge of fools. The pedant and the priest have always been the most expert of logicians—and the most diligent disseminators of nonsense and worse. The liberation of the human mind has never been furthered by dunderheads; it has been furthered by gay fellows who heaved dead cats into sanctuaries and then went roistering down the highways of the world, proving to all men that doubt, after all, was safe—that the god in the sanctuary was finite in his power and hence a fraud. One horse-laugh is worth ten thousand syllogisms. It is not only more effective; it is also vastly more intelligent.
Phlogiston interview (1995)
Context: When I started writing my first novel,... And Call Me Conrad, they always say: "Write about what you know" and I said "Well, if I get a nice sort of combination SF and Fantasy with these resonances from Greek Mythology it might be pretty good. It would also give me a chance to start filling in my background on all those things I don't know much about but should if I want to be an SF writer."
So I sat down and made a list of everything I felt I should know more about. Astrophysics, oceanography, marine biology, genetics... Then when I'd finished the list I read one book in each of these areas. When I'd finished I went back and read a second book until I'd read ten books in each area. I thought that it wouldn't turn me into a terrific, fantastic expert but I'd at least have enough material there to know if I was saying something wrong. And I'd also know where to turn to get the information I want to make it right.
While I was doing this, to keep the words and cheques flowing I wrote books involving mythology. And once I started picking up things involving astrophysics I'd write stories that played with those sorts of things. So that's why I started out with mythology.

Superman Comes to the Supermarket (1960)
Context: America is a nation of experts without roots; we are always creating tacticians who are blind to strategy and strategists who cannot take a step, and when the culture has finished its work the institutions handcuff the infirmity.
The Libertarian as Conservative (1984)
Context: Most work serves the predatory purposes of commerce and coercion and can be abolished outright. The rest can be automated away and/or transformed — by the experts, the workers who do it — into creative, playlike pastimes whose variety and conviviality will make extrinsic inducements like the capitalist carrot and the Communist stick equally obsolete. In the hopefully impending meta-industrial revolution, libertarian communists revolting against work will settle accounts with “libertarians” and “Communists” working against revolt. And then we can go for the gusto!

Wired Magazine article http://www.wired.com/wired/archive/14.08/colbert.html (14 August 2006)
Context: Get your own entry in an encyclopedia... In the media age, everybody was famous for 15 minutes. In the Wikipedia age, everybody can be an expert in five minutes. Special bonus: You can edit your own entry to make yourself seem even smarter.

The Need for Transcendence in the Postmodern World (1994)
Context: There appear to be no integrating forces, no unified meaning, no true inner understanding of phenomena in our experience of the world. Experts can explain anything in the objective world to us, yet we understand our own lives less and less. In short, we live in the postmodern world, where everything is possible and almost nothing is certain.
