5. “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

6. “Men fear thought as they fear nothing else on earth -- more than ruin, more even than death. Thought is subversive and revolutionary, destructive and terrible, thought is merciless to privilege, established institutions, and comfortable habits; thought is anarchic and lawless, indifferent to authority, careless of the well-tried wisdom of the ages. Thought looks into the pit of hell and is not afraid ... Thought is great and swift and free, the light of the world, and the chief glory of man.” - Bertrand Russell

7. “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

8. “I like the scientific spirit—the holding off, the being sure but not too sure, the willingness to surrender ideas when the evidence is against them: this is ultimately fine—it always keeps the way beyond open—always gives life, thought, affection, the whole man, a chance to try over again after a mistake—after a wrong guess.” - Walt Whitman

9. “Every now and then a man's mind is stretched by a new idea or sensation, and never shrinks back to its former dimensions.” - Oliver Wendell Holmes Sr.

10. “Imagine the people who believe such things and who are not ashamed to ignore, totally, all the patient findings of thinking minds through all the centuries since the Bible was written. And it is these ignorant people, the most uneducated, the most unimaginative, the most unthinking among us, who would make themselves the guides and leaders of us all; who would force their feeble and childish beliefs on us; who would invade our schools and libraries and homes. I personally resent it bitterly.” - Isaac Asimov

11. “Learning without thought is labour lost; thought without learning is perilous.” - Confucius

18. “All true histories contain instruction; though, in some, the treasure may be hard to find, and when found, so trivial in quantity, that the dry, shriveled kernel scarcely compensates for the trouble of cracking the nut.” - Anne Brontë

19. “There is much in this vision that will remind you of your mystics; yet between them and us there is far more difference than similarity, in respect both of the matter and the manner of our thought. For while they are confident that the cosmos is perfect, we are sure only that it is very beautiful. While they pass to their conclusion without the aid of intellect, we have used that staff every step of the way. Thus, even when in respect of conclusions we agree with your mystics rather than your plodding intellectuals, in respect of method we applaud most your intellectuals; for they scorned to deceive themselves with comfortable fantasies.” - Olaf Stapledon

20. “The succession of thoughts appears in time, but the gap between two of them is outside time. The gap itself is normally unobserved. The chance of enlightenment is missed.” - Paul Brunton

21. “Keep your heart clearAnd transparent,And you willNever be bound.A single disturbed thoughtCreates ten thousand distractions.” - Ryokan

22. “Man has no automatic code of survival. His particular distinction from all other living species is the necessity to act in the face of alternatives by means of volitional choice. He has no automatic knowledge of what is good for him or evil, what values his life depends on, what course of action it requires. Are you prattling about an instinct of self-preservation? An instinct of self-preservation is precisely what man does not possess. An 'instinct' in as unerring and automatic form of knowledge. A desire is not an instinct. A desire to live does not give you the knowledge required for living. And even man's desire to live is not automatic: your secret evil today is that that is the desire you do not hold. Your fear of death is not a love of life and will not give you the knowledge needed to keep it. Man must obtain his knowledge and choose his actions by a process of thinking, which nature will not force him to perform. Man has the power to act as his own destroyer--and that is the way he has acted through most of history.” - Ayn Rand

23. “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

26. “Thinking is learning all over again how to see, directing one's consciousness, making of every image a privileged place.” - Albert Camus

27. “I like to believe that you don't need to reach a certain goal to be happy. I prefer to think that happiness is always there, and that when things don't go the way we might like them to, it's a sign from above that something even better is right around the corner.” - David Archuleta

28. “You will always be the answer, when somebody asks me what I'm thinking about.” - Lisa Brooks

29. “Like prepositional phrases, certain structural arrangements in English are much more important than the small bones of grammar in its most technical sense. It really wouldn't matter much if we started dropping the s from our plurals. Lots of words get along without it anyway, and in most cases context would be enough to indicate number. Even the distinction between singular and plural verb forms is just as much a polite convention as an essential element of meaning. But the structures, things like passives and prepositional phrases, constitute, among other things, an implicit system of moral philosophy, a view of the world and its presumed meanings, and their misuse therefore often betrays an attitude or value that the user might like to disavow.” - Richard Mitchell

30. “How frail the human heart must be―a mirrored pool of thought.” - Sylvia Plath

31. “Amory thought how it was only the past that seemed strange and unbelievable.” - F. Scott Fitzgerald

40. “My spirit. This is a new thought. I'm not sure exactly what it means, but it suggests I'm a fighter. In a sort of brave way. It's not as if I'm never friendly. Okay, maybe I don't go around loving everybody I meet, maybe my smiles are hard to come by, but i do care for some people.” - Suzanne Collins

41. “When Coleridge tried to define beauty, he returned always to one deep thought; beauty, he said, is unity in variety! Science is nothing else than the search to discover unity in the wild variety of nature,—or, more exactly, in the variety of our experience. Poetry, painting, the arts are the same search, in Coleridge’s phrase, for unity in variety.” - Bronowski

42. “chaos of thought and passion, all confus'd.” - Alexander Pope

44. “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

48. “The vivid force of his mind prevailed, and he fared forth far beyond the flaming ramparts of the heavens and traversed the boundless universe in thought and mind.” - Lucretius

49. “It was only after two years' work that it occurred to me that I was a writer. I had no particular expectation that the novel would ever be published, because it was sort of a mess. It was only when I found myself writing things I didn't realise I knew that I said, 'I'm a writer now.' The novel had become an incentive to deeper thinking. That's really what writing is—an intense form of thought.” - Don DeLillo

50. “…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

51. “Now an extraordinary and helpful fact is that by making Mind the object of our attention, not only does the serenity which is its nature begin to well up of its own accord but its steady unchanging character itself helps spontaneously to repel all disturbing thoughts.” - Paul Brunton

It becomes dangerous, on the other hand, when, instead of awakening us to the personal life of the mind, reading tends to take its place, when the truth no longer appears to us as an ideal which we can realize only by the intimate progress of our own thought and the efforts of our heart, but as something material, deposited between the leaves of books like a honey fully prepared by others and which we need only take the trouble to reach down from the shelves of libraries and then sample passively in a perfect repose of mind and body.” - Marcel Proust

56. “We naturally like what we have been accustomed to, and are attracted towards it. [...] The same is the case with those opinions of man to which he has been accustomed from his youth; he likes them, defends them, and shuns the opposite views.” - Maimonides

57. “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

67. “There is no unmoving mover behind the movement. It is only movement. It is not correct to say that life is moving, but life is movement itself. Life and movement are not two different things. In other words, there is no thinker behind the thought. Thought itself is the thinker. If you remove the thought, there is no thinker to be found.” - Walpola Rahula

68. “We must allow ourselves to think, we must dare to think, even though we fail. It is in the nature of things that we always fail, because we suddenly find it impossible to order our thoughts, because the process of thinking requires us to consider every thought there is, every possible thought. Fundamentally we have always failed, like all the others, whoever they were, even the greatest minds. At some point, they suddenly failed and their system collapsed, as is proved by their writings, which we admire because they venture farthest into failure. To think is to fail, I thought.” - Thomas Bernhard

Defining yourself through thought is limiting yourself.” - Eckhart Tolle

76. “From time to time ponder whether you are unconsciously saying:'Truth is what I happen to be thinking at this moment.” - Idries Shah

A really made-up mind--made up properly, knowing what it knows and on what basis it knows it--is open. People close an undecided mind because they're trying to protect those sore uncertainties from getting bumped and scraped.” - John Barnese

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.
