Intelligence

Intelligence is a property of mind that encompasses many related mental abilities, such as the capacities to reason, plan, solve problems, think abstractly, comprehend ideas and language, and learn.

A

 * Man becomes man only by the intelligence, but he is man only by the heart.
 * Henri Frédéric Amiel, Journal Intime (1882), translated by Mary Augusta Ward (1885), entry for 7 April 1851.

 * You don't realize that you're intelligent until it gets you into trouble.
 * James Baldwin Interview with Julius Lester, "James Baldwin: Reflections of a Maverick" in The New York Times (27 May 1984)


 * Comprehension, inventiveness, direction, and criticism: intelligence is contained in these four words.
 * Alfred Binet Les idées modernes sur les enfants (1909), 118.


 * Some recent philosophers seem to have given their moral approval to these deplorable verdicts that affirm that the intelligence of an individual is a fixed quantity, a quantity that cannot be augmented. We must protest and react against this brutal pessimism; we will try to demonstrate that it is founded on nothing.
 * Alfred Binet, Les idées modernes sur les enfants (1909), 141.


 * An intelligent man neither allows himself to be controlled nor attempts to control others; he wishes reason alone to rule, and that always.
 * Jean de La Bruyère, Les Caractères (1688), “Of the Affections,” #71


 * She should be my counsellor, But not my tyrant. For the spirit needs Impulses from a deeper source than hers; And there are motions, in the mind of man, That she must look upon with awe.
 * William Cullen Bryant, reported in Josiah Hotchkiss Gilbert, Dictionary of Burning Words of Brilliant Writers (1895), p. 353.

C

 * There are maybe two or three thousand people in the world as smart as us, little sister. Most of them are making a living somewhere. Teaching, the poor bastards, or doing research. Precious few of them are actually in positions of power.
 * Orson Scott Card, Ender's Game p. 128


 * Clever men often have intellectual blind spots. And extremely clever men—perhaps those who are the cleverest of all—have the biggest blind spots when they depart from their areas of expertise.
 * John L. Casti, The One True Platonic Heaven (Washington, D.C.: Joseph Henry Press, 2003), p. 85


 * Your intelligence often bears the same relation to your heart as the library of a château does to its owner.
 * Nicolas Chamfort, Reflections, D. Parmée, trans. (London: 2003) #68


 * There is no such thing on earth as an uninteresting subject; the only thing that can exist is an uninterested person.
 * Gilbert K. Chesterton, Heretics (1905)


 * It has yet to be proven that intelligence has any survival value.
 * Arthur C. Clarke, clarkefoundation.org


 * Government resting upon the will and universal suffrage of the people has no anchorage except in the people's intelligence.
 * President Grover Cleveland at the celebration of the sesquicentennial of Princeton College (October 22, 1896).


 * Perhaps, in spite of her brilliance, she’s too young to realize the hostility of the world toward intelligence.
 * Mark Clifton, in Star, Bright. Originally published in Galaxy magazine (July 1952); collected in Fadiman (ed.) The Mathematical Magpie, p. 73


 * She had found the answer to her affliction—conformity! She had already learned to conceal her intelligence. So many of us break our hearts before we learn that.
 * Mark Clifton, in Star, Bright. Originally published in Galaxy magazine (July 1952); collected in Fadiman (ed.) The Mathematical Magpie, p. 75

D

 * We've reached a truly remarkable situation: a grotesque mismatch between the American intelligentsia and the American electorate. A philosophical opinion about the nature of the universe which is held by the vast majority of top American scientists, and probably the majority of the intelligentsia generally, is so abhorrent to the American electorate that no candidate for popular election dare affirm it in public. If I'm right, this means that high office in the greatest country in the world is barred to the very people best qualified to hold it—the intelligentsia—unless they are prepared to lie about their beliefs. To put it bluntly American political opportunities are heavily loaded against those who are simultaneously intelligent and honest.
 * Richard Dawkins, On Militant Atheism (February 2002)


 * It is an article of passionate faith among 'politically correct' biologists and anthropologists that brain size has no connection with intelligence; that intelligence has nothing to do with genes; and that genes are probably nasty fascist things anyway.
 * Richard Dawkins, in The Economist, Vol. 328 (1993)

E

 * We should take care not to make the intellect our god; it has, of course, powerful muscles, but no personality.
 * Albert Einstein, "The Goal of Human Existence", Out of My Later Years (1956), p. 260


 * We really seek intelligence not for the answers it may suggest to the problems of life, but because we believe it is life,—not for aid in making the will of God prevail, but because we believe it is the will of God. We love it, as we love virtue, for its own sake, and we believe it is only virtue’s other and more precise name.
 * John Erskine, The Moral Obligation to be Intelligent (1915), pp. 26-27


 * We are just one of a number of species which inhabit this planet even if we are the most intelligent. But then other species have not created nuclear weapons, started wars where millions have been killed, or engaged in discrimination against the races of their sub-species, all of which humankind has done. So who is to say which one is the most “intelligent?”
 * Lorenzo Kom'boa Ervin, Anarchism and the Black Revolution (1993)

F

 * The test of a first rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function.
 * F. Scott Fitzgerald, "The Crack-Up", Esquire Magazine (February 1936).


 * Ultimately, it would certainly be desirable to have an algorithm for the selection of an intelligence, such that any trained researcher could determine whether a candidate's intelligence met the appropriate criteria. At present, however, it must be admitted that the selection (or rejection) of a candidate's intelligence is reminiscent more of an artistic judgment than of a scientific assessment.
 * , Frames of Mind: The Theory of Multiple Intelligences, (1983)


 * Intelligence is that faculty, of mind, by which order is perceived in a situation previously considered disordered
 * H. A. Fatmi & R. W. Young, "A Definition of Intelligence", Nature 228, 97 (1970)

 * Oh, I could tell you, but you're far too clever to listen. That said, we're never too old to be students of our own behaviors, Jean-Luc.
 * Spoken by Q (played by John de Lancie) in the Star Trek: Picard Season 2 Episode 2 "Penance" (March 3, 2022) by Akiva Goldsman & Terry Matalas and Christopher Monfette (Teleplay) as well as by Michael Chabon and Akiva Goldsman & Terry Matalas and Christopher Monfette (Story).

 * Keen intelligence is two-edged, It may be used constructively or destructively like a knife, either to cut the boil of ignorance, or to decapitate one's self. Intelligence is rightly guided only after the mind has acknowledged the inescapability of spiritual law.
 * Yukteswar Giri, Autobiography of a Yogi (1946)


 * An ounce of prudence is worth a pound of cleverness.
 * Baltasar Gracián, The Art of Worldly Wisdom (1647), Maxim 92.

H

 * Cleverness has often—in our world—only a posthumous good fortune. Clever people, who have nothing but their cleverness, may be remembered as superior, but they weren't allowed to feel it at the time. Stupid people can say the most devastating things!
 * ,  Madame Solario (1956), Ch. 29. Penguin (1978), pp. 328–329.

 * Do you not see how necessary a World of Pains and troubles is to school an Intelligence and make it a Soul?
 * John Keats, Letter to George and Georgiana Keats, April 1819, in The Letters of John Keats, p. 327

L

 * Advertising may be described as the science of arresting human intelligence long enough to get money from it.
 * Stephen Leacock, The Garden of Folly, "The Perfect Salesman" (1924).


 * It is amazing how oppressive is the cleverness of some people, as if it were quite a duty in you to be clever too—
 * Letitia Elizabeth Landon, Romance and Reality (1831), Vol 1, Chapter 14.

 * When the best way to the Governor’s favour was to be intelligent, intelligence would become the fashion.
 * Somerset Maugham, The Door of Opportunity (in Collected Short Stories 2), p. 406


 * Though he had both esteem and admiration for the sensibility of the human race, he had little respect for their intelligence: man has always found it easier to sacrifice his life than to learn the multiplication table.
 * Somerset Maugham, Mr. Harrington’s Washing (in Collected Short Stories 3), p. 189


 * All the branches of Christianity suffer by the fact that they seem to be unable to take in the greatest contribution of the modern world to ethical theory, to wit, the concept of a moral obligation to be intelligent.
 * H. L. Mencken, in The Gist of Mencken: Quotations from America's Critic, p. 295

L

 * The surest way to be deceived is to think oneself more clever than others.
 * François de La Rochefoucauld, Maxims (1665–1678), Maxim 127.


 * The desire of appearing clever often prevents our becoming so.
 * François de La Rochefoucauld, Maxims (1665–1678), Maxim 199.


 * The intellect has only one failing, which to be sure, is a very considerable one. It has no conscience. Napoleon is the readiest instance of this. If his heart had borne any proportion to his brain, he had been one of the greatest men of history.
 * James Russel Lowell, reported in a Dictionary of Burning Words of Brilliant Writers (1895) by Josiah Hotchkiss Gilbert, p. 353.

M

 * I believe in "intelligence," and I believe also that there are inherited differences in intellectual ability, but I do not believe that intelligence is a simple scalar endowment that can be quantified by attaching a single figure to it—an I.Q. or the like.
 * Peter Medawar, Advice to a Young Scientist (1979).


 * I once spoke to a human geneticist who declared that the notion of intelligence was quite meaningless, so I tried calling him unintelligent. He was annoyed, and it did not appease him when I went on to ask how he came to attach such a clear meaning to the notion of lack of intelligence. We never spoke again.
 * Peter Medawar, Advice to a Young Scientist (1979).


 * I'll call "Society of Mind" this scheme in which each mind is made of many smaller processes. These we'll call agents. Each mental agent by itself can only do some simple thing that needs no mind at all. Yet when we join these agents in societies—in very special ways—this leads to true intelligence.
 * Marvin Minsky, The Society of Mind (1988).

 * We have now sunk to a depth at which the restatement of the obvious is the first duty of intelligent men.
 * George Orwell, in a review of Power: A New Social Analysis by Bertrand Russell in Adelphi (January 1939).


 * Each generation imagines itself to be more intelligent than the one that went before it, and wiser than the one that comes after it.
 * George Orwell, in a review of A Coat of Many Colours: Occasional Essays by Herbert Read, Poetry Quarterly (Winter 1945).


 * It appears to me that one defeats the fanatic precisely by not being a fanatic oneself, but on the contrary by using one's intelligence.
 * George Orwell, in a letter to Richard Rees (3 March 1949).


 * No doubt, sulking populists in every era stay mean as weasels because they despise any form of superior intelligence except shrewdness.
 * Kent Owen, Review of Profscam: Professors And The Demise Of Higher Education in The American Spectator (May 1989), p. 44.

P

 * He told me that it isn't what you do but how you do it that shows whether you are clever or not.
 * Cesare Pavese, The Moon and the Bonfire, chapter XVII, p. 99.

R

 * As the saints and prophets were often forced to practise long vigils and fastings and prayers before their ecstasies would fall upon them and their visions would appear, so Virtue in its purest and most exalted form can only be acquired by means of severe and long continued culture of the mind. Persons with feeble and untrained intellects may live according to their conscience; but the conscience itself will be defective. … To cultivate the intellect is therefore a religious duty; and when this truth is fairly recognized by men, the religion which teaches that the intellect should be distrusted and that it should be subservient to faith, will inevitably fall.
 * William Winwood Reade, The Martyrdom of Man (1872), p. 540.


 * Every thing connected with intellect is permanent.
 * William Roscoe, reported in Dictionary of Burning Words of Brilliant Writers (1895) by Josiah Hotchkiss Gilbert, p. 353.


 * The more you observe nature, the more you perceive that there is tremendous organization in all things. It is an intelligence so great that just by observing natural phenomena I come to the conclusion that a Creator exists.
 * Carlo Rubbia. The Brazilian magazine Veja asked Carlo Rubbia, winner of the Nobel Prize for Physics, “Do you believe in God?; reported in Evolution Is Not a Fact, Awake! magazine, 1998, 8/8.


 * So far as I can remember, there's not one word in the Gospels in praise of intelligence.
 * Bertrand Russell, cited in

 * Be curious. Read widely. Try new things. What people call intelligence just boils down to curiosity.
 * Aaron Swartz
 * Men of limited intelligence are so exposed to boredom and this is due to their intellect’s being absolutely nothing but the medium of motives for their will. Now if at the moment there are no motives to be taken up, the will rests and the intellect takes a holiday since the one, like the other, does not become active of its own accord. The result is a terrible stagnation of all the powers of the entire man, in a word boredom. To ward off this, men now present the will with trivial motives that are merely temporary and are taken at random in order to rouse it and thus bring into action the intellect that has to interpret them.
 * Arthur Schopenhauer, “Aphorisms on the Wisdom of Life,” Parerga und Paralipomena, E. Payne, trans. (1974) Vol. 1, p. 331.


 * So-called good society recognizes every kind of claim but that of intellect, which is a contraband article; and people are expected to exhibit an unlimited amount of patience towards every form of folly and stupidity, perversity and dullness; while personal merit has to beg pardon, as it were, for being present, or else conceal itself altogether. Intellectual superiority offends by its very existence, without any desire to do so.

 * Charles Sheffield, The Hidden Matter of McAndrew (1992), reprinted in The Compleat McAndrew (2000), ISBN 0-671-57857-X, p. 158


 * Intelligence is too subtle an attribute to be inferred from appearance.

 * We live in a culture in which intelligence is denied relevance altogether, in a search for radical innocence, or is defended as an instrument of authority and repression. In my view, the only intelligence worth defending is critical, dialectical, skeptical, desimplifying.
 * Susan Sontag, "Women, the Arts, & the Politics of Culture: An Interview with Susan Sontag" in Salmagundi, No. 31-32 (Fall/Winter 1975), p. 29; later published in Conversations with Susan Sontag (1995) edited by Leland A. Poague, p. 77.

 * The three greatest mistakes that can be made—lack of intelligence, lack of resolution, or lack of responsibility.
 * Thucydides, The Peloponnesian War, (translated by Rex Warner, in the Penguin Classics), Book 1, Chapter 9 (p. 80)


 * Until now, human intelligence, which is no more than a minute aspect of universal intelligence, has been distorted and misused by the ego. I call that “intelligence in the service of madness.” Splitting the atom requires great intelligence. Using that intelligence for building and stockpiling atom bombs is insane or at best extremely unintelligent. Stupidity is relatively harmless, but intelligent stupidity is highly dangerous. This intelligent stupidity, for which one could find countless obvious examples, is threatening our survival as a species.
 * Eckhart Tolle in A New Earth: Awakening to Your Life's Purpose,  (2005)


 * The ego may be clever, but it is not intelligent. Cleverness pursues its own little aims. Intelligence sees the larger whole in which all things are connected. Cleverness is motivated by self interest, and it is extremely shortsighted. Most politicians and business people are clever. Very few are intelligent. Whatever is attained through cleverness is shortlived and always turns out to be eventually self defeating. Cleverness divides; intelligence unites.
 * Eckhart Tolle in A New Earth: Awakening to Your Life's Purpose,  (2005)


 * Your inner body is not solid but spacious. It is not your physical form but the life that animates the physical form. It is the intelligence that created and sustains the body, simultaneously coordinating hundreds of different functions of such extraordinary complexity that the human mind can only understand a tiny fraction of it. When you become aware of it, what is really happening is that the intelligence is becoming aware of itself. It is the elusive “life” that no scientist has ever found because the consciousness that is looking for it is it.
 * Eckhart Tolle in A New Earth: Awakening to Your Life's Purpose,  (2005)

 * It was tragic, all right, but George and Hazel couldn't think about it very hard. Hazel had a perfectly average intelligence, which meant she couldn't think about anything except in short bursts. And George, while his intelligence was way above normal, had a little mental handicap radio in his ear. He was required by law to wear it at all times. It was tuned to a government transmitter. Every twenty seconds or so, the transmitter would send out some sharp noise to keep people like George from taking unfair advantage of their brains.
 * Kurt Vonnegut, Harrison Bergeron, p.1


 * Here I had tried a straightforward extrapolation of technology, and found myself precipitated over an abyss. It’s a problem we face every time we consider the creation of intelligences greater than our own. When this happens, human history will have reached a kind of singularity — a place where extrapolation breaks down and new models must be applied — and the world will pass beyond our understanding.

 * The eulogies of my intelligence are positively intended to evade the question “Is what she says true?”
 * Simone Weil, Letter to her parents, 1943


 * Just as a vagrant accused of stealing a carrot from a field stands before a comfortably seated judge who keeps up an elegant flow of queries, comments and witticisms while the accused is unable to stammer a word, so truth stands before an intelligence which is concerned with the elegant manipulation of opinions.
 * Simone Weil, Human Personality (1943), p. 68


 * There is nothing that comes closer to true humility than the intelligence. It is impossible to feel pride in one’s intelligence at the moment when one really and truly exercises it.
 * Simone Weil, Simone Weil: An Anthology (1986), p. 35


 * The intelligence is defeated as soon as the expression of one's thoughts is preceded, explicitly or implicitly, by the little word 'we'. And when the light of the intelligence grows dim, it is not very long before the love of good becomes lost.
 * Simone Weil, The Need for Roots: Prelude to a Declaration of Duties Towards Mankind (1949), p. 26


 * I grieved to think how brief the dream of the human intellect had been. It had committed suicide. It had set itself steadfastly towards comfort and ease, a balanced society with security and permanency as its watchword, it had attained its hopes—to come to this at last. Once, life and property must have reached almost absolute safety. The rich had been assured of his wealth and comfort, the toiler assured of his life and work. No doubt in that perfect world there had been no unemployed problem, no social question left unsolved. And a great quiet had followed. It is a law of nature we overlook, that intellectual versatility is the compensation for change, danger, and trouble. An animal perfectly in harmony with its environment is a perfect mechanism. Nature never appeals to intelligence until habit and instinct are useless. There is no intelligence where there is no change and no need of change. Only those animals partake of intelligence that have to meet a huge variety of needs and dangers.
 * H.G. Wells The Time Machine Chapter 10

 * Intelligence is quickness to apprehend as distinct from ability, which is capacity to act wisely on the thing apprehended.
