1. “Books are the carriers of civilization. Without books, history is silent, literature dumb, science crippled, thought and speculation at a standstill. Without books, the development of civilization would have been impossible. They are engines of change (as the poet said), windows on the world and lighthouses erected in the sea of time. They are companions, teachers, magicians, bankers of the treasures of the mind. Books are humanity in print.[Bulletin of the American Academy of Arts and Sciences, Vol. 34, No. 2 (Nov. 1980), pp. 16-32]” - Barbara Tuchman

2. “The great enemy of truth is very often not the lie--deliberate, contrived and dishonest--but the myth--persistent, persuasive and unrealistic. Too often we hold fast to the cliches of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinion without the discomfort of thought.[Commencement Address at Yale University, June 11 1962]” - John F. Kennedy

9. “Der Gedanke ist ein Vogel, der Raum braucht und in einem Käfig von Worten zwar seine Flügel ausbreiten, aber nicht fliegen kann.” - Khalil Gibran

10. “Religion can never reform mankind because religion is slavery. It is far better to be free, to leave the forts and barricades of fear, to stand erect and face the future with a smile. It is far better to give yourself sometimes to negligence, to drift with wave and tide, with the blind force of the world, to think and dream, to forget the chains and limitations of the breathing life, to forget purpose and object, to lounge in the picture gallery of the brain, to feel once more the clasps and kisses of the past, to bring life's morning back, to see again the forms and faces of the dead, to paint fair pictures for the coming years, to forget all Gods, their promises and threats, to feel within your veins life's joyous stream and hear the martial music, the rhythmic beating of your fearless heart. And then to rouse yourself to do all useful things, to reach with thought and deed the ideal in your brain, to give your fancies wing, that they, like chemist bees, may find art's nectar in the weeds of common things, to look with trained and steady eyes for facts, to find the subtle threads that join the distant with the now, to increase knowledge, to take burdens from the weak, to develop the brain, to defend the right, to make a palace for the soul. This is real religion. This is real worship” - Robert Green Ingersoll

11. “Most of our so-called thinking processes are devoted to finding excuses for going on believing as we already do. ” - Herbert M Shelton

12. “I shudder at the thought of men....I'm due to fall in love again” - Dorothy Parker

16. “Think and then think what you have thought. Is it really what you had thought. Think again.” - Dr. Amit Abraham

17. “A tornado of thought is unleashed after each new insight. This in turn results in an earthquake of assumptions. These are natural disasters that re-shape the spirit.” - Vera Nazarian

18. “As long as she thinks of a man, nobody objects to a woman thinking.” - Virginia Woolf

19. “Every woman whether rich or poor, married or single, has a circle of influence within which, according to her character, she is exerting a certain amount of power for good or harm. Every woman, by her virtue or her vice, by her folly or her wisdom, by her levity or her dignity, is adding something to our national elevation or degradation. A community is not likely to be overthrown where woman fulfills her mission, for by the power of her noble heart over the hearts of others, she will raise that community from its ruins and restore it again to prosperity and joy.” - John Angell James

20. “The key to every man is his thought. Sturdy and defying though he look, he has a helm which he obeys, which is the idea after which all his facts are classified. He can only be reformed by showing him a new idea which commands his own.” - Ralph Waldo Emerson

27. “I'd say we're all just ghosts on a wire seeking the prick of an electric thought.” - Robert Fanney

28. “On the Bigotry of Culture:: it presented us with culture, with thought as something justified in itself, that is, which requires no justification but is valid by it's own essence, whatever its concrete employment and content maybe. Human life was to put itself at the service of culture because only thus would it become charged with value. From which it would follow that human life, our pure existence was, in itself, a mean and worthless thing.” - José Ortega y Gasset

29. “Love born in the brain is more spirited, doubtless, than true love, but it has only flashes of enthusiasm; it knows itself too well, it criticizes itself incessantly; so far from banishing thought, it is itself reared only upon a structure of thought.” - Stendhal

30. “Language is the dress of thought.” - Samuel Johnson

31. “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

32. “Boring is the right thought at the wrong time.” - Jack Gardner

33. “For God’s sake, let us be mennot monkeys minding machinesor sitting with our tails curledwhile the machine amuses us, the radio or film or gramophone.Monkeys with a bland grin on our faces.” - D.H. Lawrence

34. “Some care is needed in using Descartes' argument. "I think, therefore I am" says rather more than is strictly certain. It might seem as though we are quite sure of being the same person to-day as we were yesterday, and this is no doubt true in some sense. But the real Self is as hard to arrive at as the real table, and does not seem to have that absolute, convincing certainty that belongs to particular experiences.” - Bertrand Russell

35. “If only [people] understood that every thought is both false and true! False by one-sidenedness resulting from man's inability to embrace the whole truth, and true as an expression of one fact of human endeavor.” - Leo Tolstoy

36. “Life is difficult.” - M. Scott Peck

37. “A ja myślę, że całe zło tego świata bierze się z myślenia. Zwłaszcza w wykonaniu ludzi całkiem ku temu nie mających predyspozycji. ” - Andrzej Sapkowski

40. “Sometimes when it looks like I'm deep in thought I'm just trying not to have a conversation with people.” - Pete Wentz

41. “…he is unlike the other customers. They sense it too, and look at him with hard eyes, eyes like little metal studs pinned into the white faces of young men [...] In the hush his entrance creates, the excessive courtesy the weary woman behind the counter shows him amplifies his strangeness. He orders coffee quietly and studies the rim of the cup to steady the sliding in his stomach. He had thought, he had read, that from shore to shore all America was the same. He wonders, Is it just these people I’m outside or is it all America?” - Updike, John

42. “Siddhartha has one single goal-to become empty, to become empty of thirst, desire, dreams, pleasure and sorrow-to let the Self die. No longer to be Self, to experience the peace of an emptied heart, to experience pure thought-that was his goal.” - Hermann Hesse

43. “The only way to make a library safe is to lock people out of it. As long as they are allowed to read the books 'any old time they have a mind to,' libraries will remain the nurseries of heresy and independence of thought. They will, in fact, preserve that freedom which is a far more important part of our lives than any ideology or orthodoxy, the freedom that dissolves orthodoxies and inspires solutions to the ever-changing challenges of the future. I hope that your library and mine will continue in this way to be dangerous for many years to come.” - Edmund S. Morgan

44. “Let us reflect, if we wish to be brilliant. Too much improvisation empties the mind in a stupid way. Running beer gathers no froth. No haste, gentlemen.” - Victor Hugo

45. “Insecurities have the ability to shape and mold our minds to live with everything that’s bad; like crying on the inside, while smiling on the outside…thus creating pain…but, alas, I have the answer; forget about what you thought and enjoy (embrace) what you feel” - Jeremy Aldana

46. “Fuck rational thought” - George Carlin

47. “Some minds corrode and grow inactive under the loss of personal liberty; others grow morbid and irritable; but it is the nature of the poet to become tender and imaginitive in the loneliness of confinement. He banquets upon the honey of his own thoughts, and, like the captive bird, pours forth his soul in melody.” - Washington Irving

48. “Islam is not man's ultimate justification to do as he pleases--it is, instead, a religion built on reason and evidence. If each of us asks the ustaz for the causes of his religious opinions, then we should, by doing so, help realise the principles of Islam and thus improve intellectual discussion in our own community.” - Mohd Asri Zainul Abidin

49. “Thinking can only serve to measure out the helplessness of thought.” - H. Rider Haggard

50. “Thinking is the most overrated human activity.” - Wendell Berry

51. “In what you say of another, apply the test of kindness, necessity and truth, and let nothing pass your lips without a 2/3 majority.” - Liz Armbruster

52. “I began my studies with eagerness. Before me I saw a new world opening in beauty and light, and I felt within me the capacity to know all things. In the wonderland of Mind I should be as free as another [with sight and hearing]. Its people, scenery, manners, joys, and tragedies should be living tangible interpreters of the real world. The lecture halls seemed filled with the spirit of the great and wise, and I thought the professors were the embodiment of wisdom... But I soon discovered that college was not quite the romantic lyceum I had imagined. Many of the dreams that had delighted my young inexperience became beautifully less and "faded into the light of common day." Gradually I began to find that there were disadvantages in going to college. The one I felt and still feel most is lack of time. I used to have time to think, to reflect, my mind and I. We would sit together of an evening and listen to the inner melodies of the spirit, which one hears only in leisure moments when the words of some loved poet touch a deep, sweet chord in the soul that until then had been silent. But in college there is no time to commune with one's thoughts. One goes to college to learn, it seems, not to think. When one enters the portals of learning, one leaves the dearest pleasures – solitude, books and imagination – outside with the whispering pines. I suppose I ought to find some comfort in the thought that I am laying up treasures for future enjoyment, but I am improvident enough to prefer present joy to hoarding riches against a rainy day.” - Helen Keller

53. “Pengorbanan. Kau membuat pengorbanan. Aku membuat pengorbanan. Kita semua membuat pengorbanan. Tapi kau merasa marah atas pengorbanan yang kau berikan. Kau selalu memikirkan apa yang telah kau korbankan. Kau belum mengerti. Pengorbanan adalah bagian kehidupan. Harusnya begitu. Bukanlah sesuatu untuk disesali. Tapi sesuatu untuk didambakan.” - Mitch Albom

54. “In that one stolen second, I considered the Glebe girl. She entered my mind like a burglar, them vanished again, taking nothing. It was like the humiliation of the past had been dragged instantly from my back and left somewhere on the ground.” - Markus Zusak

55. “Towel and talk, how similar are they, both wipes dry water. One on the hate and latter in the head.” - Aphole

56. “As always when he worked with this much concentration he began to feel a sense of introverting pressure. There was no way out once he was in, no genuine rest, no one to talk to who was capable of understanding the complexity (simplicity) of the problem or the approaches to a tentative solution. There came a time in every prolonged effort when he had a moment of near panic, or "terror in a lonely place," the original semantic content of the word. The lonely place was his own mind. As a mathematician he was free from subjection to reality, free to impose his ideas and designs on his own test environment. The only valid standard for his work, its critical point (zero or infinity), was the beauty it possessed, the deft strength of his mathematical reasoning. THe work's ultimate value was simply what it revealed about the nature of his intellect. What was at stake, in effect, was his own principle of intelligence or individual consciousness; his identity, in short. This was the infalling trap, the source of art's private involvement with obsession and despair, neither more nor less than the artist's self-containment, a mental state that led to storms of overwork and extended stretches of depression, that brought on indifference to life and at times the need to regurgitate it, to seek the level of expelled matter. Of course, the sense at the end of a serious effort, if the end is reached successfully, is one of lyrical exhilaration. There is air to breathe and a place to stand. The work gradually reveals its attachment to the charged particles of other minds, men now historical, the rediscovered dead; to the main structure of mathematical thought; perhaps even to reality itself, the so-called sum of things. It is possible to stand in time's pinewood dust and admire one's own veronicas and pavanes.” - Don DeLillo

57. “When I think good thoughts, I feel that man is not, after all, so bad.” - Sri Chinmoy

58. “A single thought, he considered, could do all sorts of harm. Harm to what, he wasn't sure, but he identified it as harm.” - Adam P. Knave

59. “‎All my stupid little thoughts beget stupid little thoughts, rampantly speculating every possible outcome of every possible situation until they're all done to death and none of them could ever be true.” - Bryan Lee O'Malley

60. “Each "way of thinking" has its own shape and color, which wax and wane like the moon.” - Haruki Murakami

61. “If a person's mind is controlled by forces of revenge and jealousy, it cannot express love & sympathy. And even if they show love and sympathy to others it will yield no good result. The thought will not be reflected in love but in hate.” - Virchand Raghavji Gandhi

62. “A thought to ponder: If I couldn't use words to speak, what would my life be saying?” - Evinda Lepins

63. “There is nothing more potent than thought. Deed follows word and word follows thought. And where the thought is mighty and pure, the result is mighty and pure.” - Ghandiji

64. “A great many people mistake opinions for thought.” - Herbert V. Prochnow

65. “The eyesight for an eagle is what thought is to a man.” - Dejan Stojanovic

66. “Porque se dice que los humanos no se satisfacen jamás, que se les da una cosa y siempre quieren algo más. Y se dice esto con erróneo desprecio, ya que es una de las mayores virtudes que tiene la especie y que la hace superior a los animales que se dan por satisfechos con lo que tienen.” - John Steinbeck

67. “Images have enormous power, and images freed from deep within ourselves can change us profoundly.” - Alice McCall

68. “If you're in a war, instead of throwing a hand grenade at the enemy, throw one of those small pumpkins. Maybe it'll make everyone think how stupid war is, and while they are thinking, you can throw a real grenade at them.” - Jack Handy

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 two limits of every unit of thinking are a perplexed, troubled, or confused situation at the beginning, and a cleared up, unified, resolved situation at the close.” - John Dewey

71. “The methods of increasing the degree of truth in our beliefs are well known; they consist in hearing all sides, trying to ascertain all the relevant facts, controlling our own bias by discussion with people who have the opposite bias, and cultivating a readiness to discard any hypothesis which has proved inadequate.” - Bertrand Russell

72. “Master those books you have. Read them thoroughly. Bathe in them until they saturate you. Read and reread them…digest them. Let them go into your very self. Peruse a good book several times and make notes and analyses of it. A student will find that his mental constitution is more affected by one book thoroughly mastered than by twenty books he has merely skimmed. Little learning and much pride comes from hasty reading. Some men are disabled from thinking by their putting meditation away for the sake of much reading. In reading let your motto be ‘much not many.” - Charles H. Spurgeon

73. “Everything great that has ever happened to humanity has begun as a single thought in someone's mind, and if anyone of us is capable of such a thought, then all of us has the same capacity, capability, because we're all the same.” - Yanni

74. “Expression is a function of intention and intention emanates from your thought faculty.” - Ifeanyi Enoch Onuoha

75. “Because the eye has seen, thoughts are structured upon images and not upon ideas.” - David Consuegra
