More rationality quotes

  1. I would warn against too much of a radical devotion to rationality. Rationality is an illusion, an invented concept, a construct from the mind of man. It is not a property of the universe. Rationality may be a useful tool when it suits our purposes, however, it is merely a measuring stick, calibrated against what we know of the nature of the universe - all of which may or may not be completely inaccurate.

    Derek R. AudetteDerek R. Audette quote #24
  2. The history of man is a graveyard of great cultures that came to catastrophic ends because of their incapacity for planned, rational, voluntary reaction to challenge.

    Erich FrommErich Fromm quote #92
  3. No rational argument will have a rational effect on a man who does not want to adopt a rational attitude.

    Karl PopperKarl Popper quote #27
  4. The true Enlightenment thinker, the true rationalist, never wants to talk anyone into anything. No, he does not even want to convince; all the time he is aware that he may be wrong. Above all, he values the intellectual independence of others too highly to want to convince them in important matters. He would much rather invite contradiction, preferably in the form of rational and disciplined criticism. He seeks not to convince but to arouse - to challenge others to form free opinions.

    Karl PopperKarl Popper quote #34
  5. In fact, at this point in history, the most radical, pervasive, and earth-shaking transformation would occur simply if everybody truly evolved to a mature, rational, and responsible ego, capable of freely participating in the open exchange of mutual self-esteem. There is the 'edge of history.' There would be a real New Age.

    Ken WilberKen Wilber quote #1
  6. When a society has doubts about its future, it tends to produce spokesmen whose main appeal is to the emotions, who argue from intuitions, and whose claim to be truth-bearers rests solely on intense personal feeling.

    Kenneth TynanKenneth Tynan quote #8
  7. Our knowledge of the historical worth of certain religious doctrines increases our respect for them, but does not invalidate our proposal that they should cease to be put forward as the reasons for the precepts of civilization. On the contrary! Those historical residues have helped us to view religious teachings, as it were, as neurotic relics, and we may now argue that the time has probably come, as it does in an analytic treatment, for replacing the effects of repression by the results of the rational operation of the intellect.

    Sigmund FreudSigmund Freud quote #14
  8. Pluralism lets things really exist in the each-form or distributively. Monism thinks that the all-form or collective-unit form is the only form that is rational.

    William JamesWilliam James quote #7
  9. It is undesirable to believe a proposition when there is no ground whatever for supposing it true.

    Bertrand RussellBertrand Russell quote #96
  10. The quarrel between Hume and Rousseau is symbolic: Rousseau was mad but influential, Hume was sane but had no followers.

    Bertrand RussellBertrand Russell quote #152
  11. Gradually I began to intellectually reject some of the delusionally influenced lines of thinking which had been characteristic of my orientation. This began, most recognizably, with the rejection of politically-oriented thinking as essentially a hopeless waste of intellectual effort.

    John Forbes NashJohn Forbes Nash quote #1
  12. It is the considered opinion of most members of our rational elites that, in any given difference of opinion with reality, reality is wrong.

    John Ralston SaulJohn Ralston Saul quote #40
  13. The idea, therefore, that religious faith is somehow a sacred human convention-distinguished, as it is, both by the extravagance of its claims and by the paucity of its evidence-is really too great a monstrosity to be appreciated in all its glory. Religious faith represents so uncompromising a misuse of the power of our minds that it forms a kind of perverse, cultural singularity-a vanishing point beyond which rational discourse proves impossible.

    Sam HarrisSam Harris quote #16
  14. Astrology and all these mystical things are generally signs of a weak mind; therefore as soon as they are becoming prominent in our minds, we should see a physician, take good food, and rest.

    Swami VivekanandaSwami Vivekananda quote #61
  15. Man is a rational animal - so at least I have been told. Throughout a long life, I have looked diligently for evidence in favor of this statement, but so far I have not had the good fortune to come across it, though I have searched in many countries spread over three continents.

    Bertrand RussellBertrand Russell quote #166
  16. 'Why do you doubt your senses?' [asks Marley's Ghost] 'Because,' said Scrooge, 'a little thing affects them. A slight disorder of the stomach makes them cheats. You may be an undigested bit of beef, a blot of mustard, a crumb of cheese, a fragment of an underdone potato. There's more of gravy than of grave about you, whatever you are!'

    Charles DickensCharles Dickens quote #75
  17. At the present time I seem to be thinking rationally again in the style that is characteristic of scientists. However this is not entirely a matter of joy as if someone returned from physical disability to good physical health. One aspect of this is that rationality of thought imposes a limit on a person's concept of his relation to the cosmos.

    John Forbes NashJohn Forbes Nash quote #2
  18. Dotty: Archie says the Church is a monument to irrationality. George: ... The National Gallery is a monument to irrationality! Every concert hall is a monument to irrationality! - and so is a nicely kept garden, or a lover's favour, or a home for stray dogs! You stupid woman, if rationality were the criterion for things being allowed to exist, the world would be one gigantic field of soya beans!

    Tom StoppardTom Stoppard quote #12
  19. The restoration of our world-view can come only as a result of inexorably truth-loving and recklessly courageous thought. Such thinking alone is mature enough to learn by experience how the rational, when it thinks itself out to a conclusion, passes necessarily over into the non-rational. World- and life-affirmation and ethics are non-rational. They are not justified by any corresponding knowledge of the nature of the world, but are the disposition in which, through the inner compulsion of our will-to-live, we determine our relation to the world. What the activity of this disposition of ours means in the evolution of the world, we do not know. Nor can we regulate this activity from outside; we must leave entirely to each individual its shaping and its extension. From every point of view, then, world- and life-affirmation and ethics are non-rational, and we must have the courage to admit it.

    Albert SchweitzerAlbert Schweitzer quote #18
  20. All rational action is in the first place individual action. Only the individual thinks. Only the individual reasons. Only the individual acts. -- Socialism, p. 97

    Ludwig von MisesLudwig von Mises quote #11
  21. There is no area in our minds reserved for superstition, such as the Greeks had in their mythology; and superstition, under cover of an abstract vocabulary, has revenged itself by invading the entire realm of thought. Our science is like a store filled with the most subtle intellectual devices for solving the most complex problems, and yet we are almost incapable of applying the elementary principles of rational thought. In every sphere, we seem to have lost the very elements of intelligence: the ideas of limit, measure, degree, proportion, relation, comparison, contingency, interdependence, interrelation of means and ends. To keep to the social level, our political universe is peopled exclusively by myths and monsters; all it contains is absolutes and abstract entities. This is illustrated by all the words of our political and social vocabulary: nation, security, capitalism, communism, fascism, order, authority, property, democracy. We never use them in phrases such as: There is democracy to the extent that... or: There is capitalism in so far as... The use of expressions like 'to the extent that' is beyond our intellectual capacity. Each of these words seems to represent for us an absolute reality, unaffected by conditions, or an absolute objective, independent of methods of action, or an absolute evil; and at the same time we make all these words mean, successively or simultaneously, anything whatsoever. Our lives are lived, in actual fact, among changing, varying realities, subject to the casual play of external necessities, and modifying themselves according to specific conditions within specific limits; and yet we act and strive and sacrifice ourselves and others by reference to fixed and isolated abstractions which cannot possibly be related either to one another or to any concrete facts. In this so-called age of technicians, the only battles we know how to fight are battles against windmills. [p.222]

    Simone WeilSimone Weil quote #38
  22. The irrational imposes limits on the rational, which, in its turn, gives it its moderation.

    Albert CamusAlbert Camus quote #202
  23. This conversation is bound to turn up. Two guys in a street meet each other, and one of them says, 'Hey, did you hear? Phil Davis died.' 'Phil Davis? I just saw him yesterday.' 'Yeah? : Didn't help. He died anyway. Apparently, the simple act of you seeing him did not slow down his cancer. In fact, it may have made it more aggressive. You know, you could be the cause for Phil's death. How do you live with yourself?'

    George CarlinGeorge Carlin quote #58
  24. The assumption, which served Gandhi so well in dealing with individuals, that all human beings are more or less approachable and will respond to a generous gesture, needs to be seriously questioned. It is not necessarily true, for example, when you are dealing with lunatics.

    George OrwellGeorge Orwell quote #131
  25. The dominant system of power in the west has been Platonist - a system which functions on highly developed levels of structure and law. This is the school of pure rationality and fear of the undefined - fear of doubt. The minority system has been Socratic or humanist. It is interested in doubt and not overwhelmed by the Platonist-Hobbesian desperate need to tie things down.

    John Ralston SaulJohn Ralston Saul quote #68
  26. One cannot take up a leading article in even the foremost papers dealing with foreign relations, without finding it assumed that European governments have the instincts of savages and the foresight of cattle-lifters. Are we to assume that the governments of the world, which presumably are directed by men as farsighted as bankers, are permanently to fall below the banker in their conception of enlightened self-interest?

    Norman AngellNorman Angell quote #7
  27. He has a profound and warm belief in what he calls in one of his books 'the potential rationalism of mankind'. Let us hope that his optimism may be vindicated.

    Norman AngellNorman Angell quote #51
  28. We could have no communication whatever with our surroundings if they were absolutely foreign to us. Man is reaping success every day, and that shows there is a rational connection between him and nature, for we never can make anything our own except that which is truly related to us.

    Rabindranath TagoreRabindranath Tagore quote #171
  29. We are no more free to believe whatever we want about God than we are free to adopt unjustified beliefs about science or history, or free to mean whatever we want when using words like 'poison' or 'north' or 'zero.'[2]

    Sam HarrisSam Harris quote #13
  30. Faith is what credulity becomes when it finally achieves escape velocity from the constraints of terrestrial discourse.[2]

    Sam HarrisSam Harris quote #15
  31. The difficultest rigor is forthwith, On the image of what we see, to catch from that Irrational moment its unreasoning, As when the sun comes rising, when the sea Clears deeply, when the moon hangs on the wall Of heaven-haven. These are not things transformed. Yet we are shaken by them as if they were. We reason about them with a later reason.

    Wallace StevensWallace Stevens quote #150
  32. The best comedy is always heartless, an alternative to rational emotion.

    Wilfrid SheedWilfrid Sheed quote #23
  33. I've always wanted to make the world a more rational place. I'm still working on it.

    Penn JillettePenn Jillette quote #1
  34. The measure of our rationality determines the degree of vividness with which we appreciate the needs of other life, the extent to which we become conscious of the real character of our own motives and impulses, the ability to harmonize conflicting impulses in our own life and in society, and the capacity to choose adequate means for approved ends.

    Reinhold NiebuhrReinhold Niebuhr quote #5
  35. History does not record anywhere at any time a religion that has any rational basis. Religion is a crutch for people not strong enough to stand up to the unknown without help. But, like dandruff, most people do have a religion and spend time and money on it and seem to derive considerable pleasure from fiddling with it.

    Robert A. HeinleinRobert A. Heinlein quote #86
  36. Talk about rationality can get very confusing unless the things with which rationality deals are also included.

    Robert M. PirsigRobert M. Pirsig quote #15
