7. “Henry's universe was modeled on the highball. It was a mixture in which half a pint of the fizziest philosophical and scientific ideas all but drowned a small jigger of immediate experience, most of it strictly sexual. Broken reeds are seldom good mixers. They're far too busy with their ideas, their sensuality and their psychosomatic complaints to be able to take an interest in other people - even their own wives and children. They live in a state of the most profound voluntary ignorance, not knowing anything about anybody, but abounding in preconceived opinions about everything.” - Aldous Huxley

8. “For books are not absolutely dead things, but do contain a potency of life in them to be as active as that soul was whose progeny they are; nay, they do preserve as in a vial the purest efficacy and extraction of that living intellect that bred them.” - John Milton

13. “Where instinct fails, intellect must venture.” - Jim Butcher

14. “We are on strike, we, the men of the mind.We are on strike against self-immolation. We are on strike against the creed of unearned rewards and unrewarded duties. We are on strike against the dogma that the pursuit of one's happiness is evil. We are on strike against the doctrine that life is guilt.” - Ayn Rand

15. “Because there are three classes of intellects: one which comprehends by itself; another which appreciates what others comprehend; and a third which neither comprehends by itself nor by the showing of others; the first is the most excellent, the second is good, the third is useless.” - Niccolo Machiavelli

18. “The intellectual attainments of a man who thinks for himself resemble a fine painting, where the light and shade are correct, the tone sustained, the colour perfectly harmonised; it is true to life. On the other hand, the intellectual attainments of the mere man of learning are like a large palette, full of all sorts of colours, which at most are systematically arranged, but devoid of harmony, connection and meaning.” - Arthur Schopenhauer

19. “The acquisition of knowledge is always of use to the intellect, because it may thus drive out useless things and retain the good. For nothing can be loved or hated unless it is first known.” - Leonardo da Vinci

21. “People are wrong when they think that an unemployed man only worries about losing his wages; on the contrary, an illiterate man, with the work habit in his bones, needs work even more than he needs money. An educated man can put up with enforced idleness, which is one of the worst evils of poverty. But a man like Paddy, with no means of filling up time, is as miserable out of work as a dog on the chain. That is why it is such nonsense to pretend that those who have 'come down in the world' are to be pitied above all others.The man who really merits pity is the man who has been down from the start,and faces poverty with a blank, resourceless mind.” - George Orwell

22. “As a convinced atheist, I ought to agree with Voltaire that Judaism is not just one more religion, but in its way the root of religious evil. Without the stern, joyless rabbis and their 613 dour prohibitions, we might have avoided the whole nightmare of the Old Testament, and the brutal, crude wrenching of that into prophecy-derived Christianity, and the later plagiarism and mutation of Judaism and Christianity into the various rival forms of Islam. Much of the time, I do concur with Voltaire, but not without acknowledging that Judaism is dialectical. There is, after all, a specifically Jewish version of the eighteenth-century Enlightenment, with a specifically Jewish name—the Haskalah—for itself. The term derives from the word for 'mind' or 'intellect,' and it is naturally associated with ethics rather than rituals, life rather than prohibitions, and assimilation over 'exile' or 'return.' It's everlastingly linked to the name of the great German teacher Moses Mendelssohn, one of those conspicuous Jewish hunchbacks who so upset and embarrassed Isaiah Berlin. (The other way to upset or embarrass Berlin, I found, was to mention that he himself was a cousin of Menachem Schneerson, the 'messianic' Lubavitcher rebbe.) However, even pre-enlightenment Judaism forces its adherents to study and think, it reluctantly teaches them what others think, and it may even teach them how to think also.” - Christopher Hitchens

23. “... the mind was designed not to defend what we want, but to discover what is ultimately true, which should shape our wants and satisfy them more deeply with God. The purpose of the mind is not to rationalize subjective preferences, but to recognize objective reality and to help the heart revel in God.” - John Piper

24. “I am a brain, Watson. The rest of me is a mere appendix.” - Arthur Conan Doyle

25. “The truth is that personality inevitably bleeds into all forms of our intellectual life. We all extrapolate from our own lives in order to understand the world.” - Siri Hustvedt

26. “If a man has a capacity for great thoughts, he is likely to overtake them before he is decrepit.” - George Eliot

27. “I wonder if anyone but me realizes what goes on in that head back of your deceptively sweet face.” - Margaret Mitchell

28. “How very paltry and limited the normal human intellect is, and how little lucidity there is in the human consciousness, may be judged from the fact that, despite the ephemeral brevity of human life, the uncertainty of our existence and the countless enigmas which press upon us from all sides, everyone does not continually and ceaselessly philosophize, but that only the rarest of exceptions do.” - Arthur Schopenhauer

29. “Google' is not a synonym for 'research'.” - Dan Brown

30. “There were sins whose fascination was more in the memory than in the doing of them, strange triumphs that gratified the pride more than the passions, and gave to the intellect a quickened sense of joy, greater than any joy they brought, or could ever bring, to the senses.” - Oscar Wilde

31. “I sought her eye, desirous to read there the intelligence which I could not discern in her face or hear in her conversation; it was merry, rather small; by turns I saw vivacity, vanity, coquetry, look out through its irid, but I watched in vain for a glimpse of soul. I am no Oriental; white necks, carmine lips and cheeks, clusters of bright curls, do not suffice for me without that Promethean spark which will live after the roses and lilies are faded, the burnished hair grown grey. In sunshine, in prosperity, the flowers are very well; but how many wet days are there in life--November seasons of disaster, when a man's hearth and home would be cold indeed, without the clear, cheering gleam of intellect.” - Charlotte Brontë

32. “Our intelligence cannot wall itself up alive, like a pupa in a chrysalis. It must at any cost keep on speaking terms with the universe that engendered it.” - William James

33. “I only know that I know nothing” - Socrates

34. “Ideas are the source of all things” - Plato

35. “My dear boy, the people who only love once in their lives are really the shallow people. What they call their loyalty, and their fidelity, I call either the lethargy of custom or their lack of imagination. Faithfulness is to the emotional life what consistency is to the life of the intellect—simply a confession of failures.” - Oscar Wilde

36. “Emotions are like muscles. Most of them go highly unattended, it's usually the weaker, undefined ones that cause injury to the rest, and there is most certainly memory response in play.” - Erica Goros

37. “It is not excess of thought but defect of fertile and generous emotion that marks them out. Their heads are no bigger than the ordinary: it is the atrophy of te chest beneath that makes them seem so.” - C.S. Lewis

39. “A man can live on his wits and his balls for only so long.” - Hunter S. Thompson

40. “I have a realistic grasp of my own strengths and weaknesses. My mind is my weapon. My brother has his sword, King Robert has his warhammer, and I have my mind… and a mind needs books as a sword needs a whetstone, if it is to keep its edge. That’s why I read so much, Jon Snow.” - George R.R. Martin

41. “No one can be a great thinker who does not recognize that as a thinker it is his first duty to follow his intellect to whatever conclusions it may lead.” - John Stuart Mill

42. “An intellectual is some one who isn't exactly distinguished by his intellect. He claims that label to compensates for his inadequacies.” - Carlos Ruiz Zafon

45. “Muscle is good, but craft is better” - Wace

46. “It is a secret which every intellectual man quickly learns, that, beyond the energy of his possessed and conscious intellect, he is capable of a new energy (as of an intellect doubled on itself), by abandonment to the nature of things; that, beside his privacy of power as an individual man, there is a great public power, on which he can draw, by unlocking, at all risks, his human doors, and suffering the ethereal tides to roll and circulate through him: then is he caught up into the life of the Universe, his speech is thunder, his thought is law, and his words are universally intelligible as the plants and animals.” - Ralph Waldo Emerson

47. “...When a man first awakens, it sometimes takes several moments before he starts thinking clearly.""And here I thought it took several years, perhaps a lifetime for the average man's intellect to kick in.” - Karen Marie Moning

48. “Man's mind may be likened to a garden, which may be intelligently cultivated or allowed to run wild.” - James Allen

49. “If I show up at your house ten years from now and find nothing in your living room but The Readers Digest, nothing on your bedroom night table but the newest Dan Brown novel, and nothing in your bathroom but Jokes for the John, I’ll chase you down to the end of your driveway and back, screaming ‘Where are your books?

51. “لن يكون مصير الوهابية السياسي حيث نجحت واستقرت بأفضل من مصير التحديثية العصرية فالانطواء على الذات تحت شعار العودة للتقاليد الحنيفة كالاندماج بالغرب تحت شعار الحداثة ماكان يعني الا المحافظة على المصالح الاجتماعية التقليدية نفسها للنخبة الأقلية القديمة او الحديثة وصيانتها في وجه مصالح الأغلبية الشعبية كلاهما أدى الى النتائج ذاتها ” - برهان غليون

53. “كل الحركات العربية الحديثة  ليست إلا حركة واحدة الواحدة  لتكديح الشعب  اي تحويل الشعب الى عمالة مأجورة ورثّة هنا بالضرورة  من اجل رفع وتعظيم الفائض الاقتصادي والتكديح لا يعني فقط فصل المنتج عن وسائل الانتاج ولا بالضرورة تحرير قوة العمل لدفعها الى سوق العمل لكنه تجريد كلي للمنتج عن كل نظام عقلي ومباديء وقيم وعن كل سلطة سياسية لتكوين قوة عمل مجردة ومكرسة في حياتها الفانية والأبدية للإنتاج  ” - برهان غليون

54. “ليس هناك أيديولوجية لا تقوم الثورة إلا بها بقدر ما أن ليس هناك ثورة تقوم بها طبقة واحدة أيديولوجية ” - برهان غليون

55. “But genius, and even great talent, springs less from seeds of intellect and social refinement superior to those of other people than from the faculty of transforming and transposing them. To heat a liquid with an electric lamp requires not the strongest lamp possible, but one of which the current can cease to illuminate, can be diverted so as to give heat instead of light. To mount the skies it is not necessary to have the most powerful of motors, one must have a motor which, instead of continuing to run along the earth's surface, intersecting with a vertical line the horizontal line which it began by following, is capable of converting its speed into lifting power. Similarly, the men who produce works of genius are not those who live in the most delicate atmosphere, whose conversation is the most brilliant or their culture the most extensive, but those who have had the power, ceasing suddenly to live only for themselves, to transform their personality into a sort of mirror, in such a way that their life, however mediocre it may be socially and even, in a sense, intellectually, is reflected by it, genius consisting in reflecting power and not int he intrinsic quality of the scene reflected.” - Marcel Proust

56. “Arousal begins within the mind, then seeps out where fantasy propels physicality.” - Kristie LeVangie

57. “It is fortunate for this community that I am not a criminal.” - Arthur Conan Doyle

58. “Since art is a virtue of the intellect, it demands to communicate with the entire universe of the intellect. Hence it is that the normal climate of art is intelligence and knowledge: its normal soil, the civilized heritage of a consistent and integrated system of beliefs and values; its normal horizon , the infinity of human experience enlighted by the passionate insight of anguish or the intellectual virtues of a contemplative mind.” - Jacques Maritain

59. “It’s not that I didn’t understand or believe the gospel before. I did. But the truth of the gospel hadn’t moved from my mind to my heart. There was a huge gap between my intellect and my emotions. The Puritan Jonathan Edwards likened his reawakening to the gospel to a man who had known, in his head, that honey was sweet, but for the first time had that sweetness burst alive in his mouth.” - J.D. Greear

60. “Upon the one thing every writer absolutely must have, and that is intellectual curiosity.” - Phillip Athans

61. “There is in every intellect a natural exigency for a true concept of God: we are born with the thirst to know and to see Him, and therefore it cannot be otherwise.” - Thomas Merton

63. “The detective story is the normal recreation of noble minds.” - Philip Guedalla

64. “[T]he more clamour we make about 'the women's point of view', the more we rub it into people that the women's point of view is different, and frankly I do not think it is -- at least in my job. The line I always want to take is, that there is the 'point of view' of the reasonably enlightened human brain, and that this is the aspect of the matter which I am best fitted to uphold.” - Dorothy L. Sayers

65. “Allow intelligent design into science textbooks, lecture halls, and laboratories, and the cost to the frontier of scientific discovery—the frontier that drives the economies of the future—would be incalculable. I don't want students who could make the next major breakthrough in renewable energy sources or space travel to have been taught that anything they don't understand, and that nobody yet understands, is divinely constructed and therefore beyond their intellectual capacity. The day that happens, Americans will just sit in awe of what we don't understand, while we watch the rest of the world boldly go where no mortal has gone before.” - Neil deGrasse Tyson

66. “Growth of consciousness does not depend on the might of the intellect but on the conviction of the heart.” - Wayne Gerard Trotman

67. “It is better to have a fair intellect that is well used, than a powerful one that is idle.” - Bryant McGill

68. “For the Word of God is not received by faith if it flits about in the top of the brain, but when it takes root in the depth of the heart . . . the heart's distrust is greater than the mind's blindness. It is harder for the heart to be furnished with assurance [of God's love] than for the mind to be endowed with thought.” - John Calvin

69. “A certain amount of reverie is good, like a narcotic in discreet doses. It soothes the fever, occasionally high, of the brain at work, and produces in the mind a soft, fresh vapor that corrects the all too angular contours of pure thought, fills up the gaps and intervals here and there, binds them together, and dulls the sharp corners of ideas. But too much reverie submerges and drowns. Thought is the labor of the intellect, reverie it's pleasure. To replace thought with reverie is to confound poison with nourishment.” - Victor Hugo

70. “The Sufi way is through knowledge and practice, not through intellect and talk.” - Idries Shah

74. “The Islamic intellectual tradition has usually not seen a dichotomy between intellect and intuition but has created a hierarchy of knowledge and methods of attaining knowledge according to which degrees of both intellection and intuition become harmonized in an order encompassing all the means available to man to know, from sensual knowledge an reason to intellection and inner version or the "knowledge of the heart.” - Seyyed Hossein Nasr

75. “Our intellect is not intended to be an end in itself, but only a means to the very mind of God.” - Ravi Zacharias

76. “Genius is a sovereign power; it forms schools; it lays hold on the spirits of men, with irresistible might; and it exercises an immeasurable influence on the whole condition of human life. This sovereignty of genius is a gift of God, possessed only by his grace. It is subject to no one and is responsible to him alone who has granted it this ascendancy.” - Abraham Kuyper

77. “God created hand, head, and heart; the hand for the deed, the head for the world, the heart for mysticism.” - Abraham Kuyper
