“Making itself intelligible is suicide for philosophy.”

Contributions to Philosophy (From Enowning) [Beitrage Zur Philosophie (Vom Ereignis)], notes of 1936–1938, as translated by Parvis Emad and Kenneth Maly (1989)
Context: Making itself intelligible is suicide for philosophy. Those who idolize "facts" never notice that their idols only shine in a borrowed light.
Context: Those in the crossing must in the end know what is mistaken by all urging for intelligibility: that every thinking of being, all philosophy, can never be confirmed by "facts," ie, by beings. Making itself intelligible is suicide for philosophy. Those who idolize "facts" never notice that their idols only shine in a borrowed light. They are also meant not to notice this; for thereupon they would have to be at a loss and therefore useless. But idolizers and idols are used wherever gods are in flight and so announce their nearness.

“The romantic is always intelligent”

Part 2, Chapter 1 (pages 45-46)
Notes from Underground (1864)
Context: The characteristics of our "romantics" are absolutely and directly opposed to the transcendental European type, and no European standard can be applied to them. (Allow me to make use of this word "romantic" — an old-fashioned and much respected word which has done good service and is familiar to all.) The characteristics of our romantics are to understand everything, to see everything and to see it often incomparably more clearly than our most realistic minds see it; to refuse to accept anyone or anything, but at the same time not to despise anything; to give way, to yield, from policy; never to lose sight of a useful practical object (such as rent-free quarters at the government expense, pensions, decorations), to keep their eye on that object through all the enthusiasms and volumes of lyrical poems, and at the same time to preserve "the sublime and the beautiful" inviolate within them to the hour of their death, and to preserve themselves also, incidentally, like some precious jewel wrapped in cotton wool if only for the benefit of "the sublime and the beautiful." Our "romantic" is a man of great breadth and the greatest rogue of all our rogues, I assure you.... I can assure you from experience, indeed. Of course, that is, if he is intelligent. But what am I saying! The romantic is always intelligent, and I only meant to observe that although we have had foolish romantics they don't count, and they were only so because in the flower of their youth they degenerated into Germans, and to preserve their precious jewel more comfortably, settled somewhere out there — by preference in Weimar or the Black Forest.

“Neither a lofty degree of intelligence nor imagination nor both together go to the making of genius. Love, love, love, that is the soul of genius.”

Wolfgang Amadeus Mozart (1756–1791) Austrian Romantic composer

True genius without heart is a thing of nought - for not great understanding alone, not intelligence alone, nor both together, make genius. Love! Love! Love! that is the soul of genius. - Nikolaus Joseph von Jacquin, entry in Mozart's souvenir album (1787-04-11) from Mozart: A Life by Maynard Solomon [Harper-Collins, 1966, ISBN 0-060-92692-9], p. 312.

“If you want your children to be intelligent, read them fairy tales. If you want them to be more intelligent, read them more fairy tales.”

Albert Einstein (1879–1955) German-born physicist and founder of the theory of relativity

Found in Montana Libraries: Volumes 8-14 (1954), p. cxxx http://books.google.com/books?id=PpwaAAAAMAAJ&q=%22more+fairy+tales%22#search_anchor. The story is given as follows: "In the current New Mexico Library Bulletin, Elizabeth Margulis tells a story of a woman who was a personal friend of the late dean of scientists, Dr. Albert Einstein. Motivated partly by her admiration for him, she held hopes that her son might become a scientist. One day she asked Dr. Einstein's advice about the kind of reading that would best prepare the child for this career. To her surprise, the scientist recommended 'Fairy tales and more fairy tales.' The mother protested that she was really serious about this and she wanted a serious answer; but Dr. Einstein persisted, adding that creative imagination is the essential element in the intellectual equipment of the true scientist, and that fairy tales are the childhood stimulus to this quality." However, it is unclear from this description whether Margulis heard this story personally from the woman who had supposedly had this discussion with Einstein, and the relevant issue of the New Mexico Library Bulletin does not appear to be online.
Variant: "First, give him fairy tales; second, give him fairy tales, and third, give him fairy tales!" Found in The Wilson Library Bulletin, Vol. 37 from 1962, which says on p. 678 http://books.google.com/books?id=KfQOAQAAMAAJ&q=einstein#search_anchor that this quote was reported by "Doris Gates, writer and children's librarian".

“The fundamental cause of the trouble is that in the modern world the stupid are cocksure while the intelligent are full of doubt.”

Bertrand Russell (1872–1970) logician, one of the first analytic philosophers and political activist

Often paraphrased as "The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts."
Compare: "One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision." B. Russell, New Hopes for a Changing World (1951). Compare also: "The best lack all conviction, while the worst / Are full of passionate intensity." W. B. Yeats, The Second Coming (1919).

Max Planck photo

“As a man who has devoted his whole life to the most clearheaded science, to the study of matter, I can tell you as a result of my research about the atoms this much: There is no matter as such! All matter originates and exists only by virtue of a force which brings the particles of an atom to vibration and holds this most minute solar system of the atom together…. We must assume behind this force the existence of a conscious and intelligent Spirit. This Spirit is the matrix of all matter.”

Max Planck (1858–1947) German theoretical physicist

Das Wesen der Materie [The Nature of Matter], a 1944 speech in Florence, Italy, Archiv zur Geschichte der Max‑ Planck‑ Gesellschaft, Abt. Va, Rep. 11 Planck, Nr. 1797; the German original is as quoted in The Spontaneous Healing of Belief https://archive.org/stream/GreggBradenTheSpontaneousHealingOfBelief/Gregg%20Braden/Gregg%20Braden%20-%20The%20Spontaneous%20Healing%20Of%20Belief#page/n1 (2008) by Gregg Braden, p. 212; Braden mistranslates intelligenten Geist as "intelligent Mind", which is an obvious tautology.

Mikhail Bakunin photo

“Unity is the great goal toward which humanity moves irresistibly. But it becomes fatal, destructive of the intelligence, the dignity, the well-being of individuals and peoples whenever it is formed without regard to liberty, either by violent means or under the authority of any theological, metaphysical, political, or even economic idea.”

"Federalism, Socialism, Anti-Theologism" http://www.marxists.org/reference/archive/bakunin/works/various/reasons-of-state.htm (Fédéralisme, socialisme et antithéologisme), presented originally as a Reasoned Proposal to the Central Committee of the League for Peace and Freedom, at the League's first congress held in Geneva (September 1867)
"Reasoned Proposal to the Central Committee of the League for Peace and Freedom" also known as "Federalism, Socialism, Anti-Theologism" (September 1867)
Context: Unity is the great goal toward which humanity moves irresistibly. But it becomes fatal, destructive of the intelligence, the dignity, the well-being of individuals and peoples whenever it is formed without regard to liberty, either by violent means or under the authority of any theological, metaphysical, political, or even economic idea. That patriotism which tends toward unity without regard to liberty is an evil patriotism, always disastrous to the popular and real interests of the country it claims to exalt and serve. Often, without wishing to be so, it is a friend of reaction – an enemy of the revolution, i. e., the emancipation of nations and men.

“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 (1903–1950) English author and journalist

Review of A Coat of Many Colours: Occasional Essays by Herbert Read, Poetry Quarterly (Winter 1945)
Context: Each generation imagines itself to be more intelligent than the one that went before it, and wiser than the one that comes after it. This is an illusion, and one should recognise it as such, but one ought also to stick to one's own world-view, even at the price of seeming old-fashioned: for that world-view springs out of experiences that the younger generation has not had, and to abandon it is to kill one's intellectual roots.

“I allow neither the bootmaker nor the architect nor the savant to impose his authority upon me. I listen to them freely and with all the respect merited by their intelligence, their character, their knowledge, reserving always my incontestable right of criticism and censure. I do not content myself with consulting authority in any special branch; I consult several; I compare their opinions, and choose that which seems to me the soundest. But I recognize no infallible authority, even in special questions; consequently, whatever respect I may have for the honesty and the sincerity of such or such an individual, I have no absolute faith in any person. Such a faith would be fatal to my reason, to my liberty, and even to the success of my undertakings; it would immediately transform me into a stupid slave, an instrument of the will and interests of others.”

God and the State (1871; publ. 1882)
Context: Does it follow that I reject all authority? Far from me such a thought. In the matter of boots, I refer to the authority of the bootmaker; concerning houses, canals, or railroads, I consult that of the architect or engineer. For such or such special knowledge I apply to such or such a savant. But I allow neither the bootmaker nor the architect nor the savant to impose his authority upon me. I listen to them freely and with all the respect merited by their intelligence, their character, their knowledge, reserving always my incontestable right of criticism and censure. I do not content myself with consulting authority in any special branch; I consult several; I compare their opinions, and choose that which seems to me the soundest. But I recognize no infallible authority, even in special questions; consequently, whatever respect I may have for the honesty and the sincerity of such or such an individual, I have no absolute faith in any person.

“To admit that an opponent might be both honest and intelligent is felt to be intolerable. It is more immediately satisfying to shout that he is a fool or a scoundrel, or both, than to find out what he is really like.”

George Orwell (1903–1950) English author and journalist

"As I Please," Tribune (8 December 1944)<sup> http://alexpeak.com/twr/tdoaom/</sup>
"As I Please" (1943–1947)
Context: The important thing is to discover which individuals are honest and which are not, and the usual blanket accusation merely makes this more difficult. The atmosphere of hatred in which controversy is conducted blinds people to considerations of this kind. To admit that an opponent might be both honest and intelligent is felt to be intolerable. It is more immediately satisfying to shout that he is a fool or a scoundrel, or both, than to find out what he is really like. It is this habit of mind, among other things, that has made political prediction in our time so remarkably unsuccessful.

“All intelligent persons also possess some larger-scale frame-systems whose members seemed at first impossibly different — like water with electricity, or poetry with music. Yet many such analogies — along with the knowledge of how to apply them — are among our most powerful tools of thought.”

Marvin Minsky (1927–2016) American cognitive scientist

Jokes and their Relation to the Cognitive Unconscious (1980)
Context: All intelligent persons also possess some larger-scale frame-systems whose members seemed at first impossibly different — like water with electricity, or poetry with music. Yet many such analogies — along with the knowledge of how to apply them — are among our most powerful tools of thought. They explain our ability sometimes to see one thing — or idea — as though it were another, and thus to apply knowledge and experience gathered in one domain to solve problems in another. It is thus that we transfer knowledge via the paradigms of Science. We learn to see gases and fluids as particles, particles as waves, and waves as envelopes of growing spheres.

“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.”

Context: I always disagree, however, when people end up saying that we can only combat Communism, Fascism or what not if we develop an equal fanaticism. 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.

“I concluded that women are flawed. There is something mentally wrong with the way their brains are wired, as if they haven’t evolved from animal-like thinking. They are incapable of reason or thinking rationally. They are like animals, completely controlled by their primal, depraved emotions and impulses. That is why they are attracted to barbaric, wild, beast-like men. They are beasts themselves. Beasts should not be able to have any rights in a civilized society. If their wickedness is not contained, the whole of humanity will be held back from advancement to a more civilized state. Women should not have the right to choose who to mate with. That choice should be made for them by civilized men of intelligence. If women had the freedom to choose which men to mate with, like they do today, they would breed with stupid, degenerate men, which would only produce stupid, degenerate offspring. This in turn would hinder the advancement of humanity. Not only hinder it, but devolve humanity completely. Women are like a plague that must be quarantined. When I came to this brilliant, pefect revelation, I felt like everything was now clear to me, in a bitter, twisted way. I am one of the few people on this world who has the intelligence to see this. I am like a god, and my purpose is to exact ultimate Retribution on all of the impurities I see in the world.”

“To laugh often and much; To win the respect of intelligent people and the affection of children; To earn the appreciation of honest critics and endure the betrayal of false friends; To appreciate beauty, to find the best in others; To leave the world a bit better, whether by a healthy child, a garden patch or a redeemed social condition; To know even one life has breathed easier because you have lived. This is to have succeeded.”
