1. “To teach how to live without certainty, and yet without being paralyzed by hesitation, is perhaps the chief thing that philosophy, in our age, can still do for those who study it.”

3. “I would never die for my beliefs because I might be wrong.”

6. “Of all forms of caution, caution in love is perhaps the most fatal to true happiness.”

7. “Our great democracies still tend to think that a stupid man is more likely to be honest than a clever man, and our politicians take advantage of this prejudice by pretending to be even more stupid than nature made them.”

21. “Those who have never known the deep intimacy and the intense companionship of happy, mutual love have missed the best thing that life has to give.”

22. “I have sought love first, because it brings ecstasy—ecstasy so great that I would often have sacrificed all the rest of life for a few hours of this joy. I have sought it next, because it relieves loneliness—that terrible loneliness in which one shivering consciousness looks over the rim of the world into the cold unfathomable lifeless abyss. I have sought it finally, because in the union of love, I have seen in a mystic miniature, the prefiguring vision of heaven that saints and poets have imagined. This is what I sought, and though it might seem too good for human life, this is what—at last—I have found.”

23. “Love and knowledge, so far as they were possible, led upward toward the heavens. But always pity brought me back to earth.”

31. “We love our habits more than our income, often more than our life.”

32. “The root of the matter is a very simple and old fashioned thing—love or compassion. If you feel this, you have a motive for existence, a guide for action, a reason for courage, an imperative necessity for intellectual honesty.”

33. “When considering marriage, one should ask oneself this question, ‘Will I be able to talk with this person into old age?’ Everything else is transitory; the most time is spent in conversation.”

34. “With equal passion, I have sought knowledge. I have wished to understand the hearts of men. I have wished to know why the stars shine. And I have tried to apprehend the Pythagorean power by which number holds sway above the flux. A little of this, but not much, I have achieved.”

35. “The use of self control is like the use of brakes on a train. It is useful when you find yourself in wrong direction, but merely harmful when the direction is right.”

36. “The infliction of cruelty with a good conscience is a delight to moralists. That is why they invented Hell.”

37. “If throughout your life you abstain from murder, theft, fornication, perjury, blasphemy, and disrespect toward your parents, church, and your king, you are conventionally held to deserve moral admiration even if you have never done a single kind, generous or useful action. This very inadequate notion of virtue is an outcome of taboo morality, and has done untold harm.”

38. “If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance to his instincts, he will accept it even on the slightest evidence. The origin of myths is explained in this way.”

39. “Sin is geographical.”

40. “Science can teach us—and I think our hearts can teach us—no longer to look around for imaginary supporters, no longer to invent allies in the , but rather to look to our own efforts here below to make the world a fit place to live.”

41. “We want to stand upon our own feet and look fair and square at the world—its good facts, its bad facts, its beauties, and its ugliness; see the world as it is and not be afraid of it.”

42. “A good world needs knowledge, kindliness, and courage; it does not need a regretful hankering after the past or a fettering of the free intelligence by words uttered long ago by ignorant men. It needs a fearless outlook and free intelligence. It needs hope for the future, not looking back all the time toward a past that is dead, which we will be far surpassed by the future that our intelligence can create.”

43. “Remember your humanity, and forget the rest.”

44. “Man is a credulous animal, and must believe something—in the absence of good grounds for belief, he will be satisfied with bad ones.”

45. “Life is nothing but a competition to be the criminal rather than the victim.”

46. “If we were all given by the power to read each other’s thoughts, I suppose the first effect would be almost all friendships would be dissolved; the second effect, however, might be excellent, for a world without any friends would be felt to be intolerable, and we should learn to like each other without needing a veil of illusion to conceal from ourselves that we did not think each other absolutely perfect.”

47. “Patience and boredom are closely related. Boredom, a certain kind of boredom, is really impatience. You don’t like the way things are, they aren’t interesting enough for you, so you decide—and boredom is a decision—that you are bored.”

48. “It is a waste of energy to be angry with a man who behaves badly, just as it is to be angry with a car that won’t go.”

49. “Boredom is therefore a vital problem for the moralist, since at least half the sins of mankind are caused by the fear of it.”

50. “Morality in sexual relations, when it is free from superstition, consists essentially in respect for the other person, and unwillingness to use that person solely as a means of personal gratification, without regard to his or her desires.”

51. “You see in the moon the sort of thing to which the earth is tending—something dead, cold, and lifeless.”

52. “The life of man is a long march through the night, surrounded by invisible foes, tortured by weariness and pain, towards a goal that few can hope to reach, and where none may tarry long.”

53. “One of the most powerful of all our passions is the desire to be admired and respected.”

54. “We have in fact, two kinds of morality, side by side—one which we preach, but do not practice, and another which we practice, but seldom preach.”

55. “I think that there is far too much work done in the world, that immense harm is caused by the belief that work is virtuous, and that what needs to be preached in modern industrial countries is quite different from what always has been preached.”

56. “Every isolated is, in isolation, insane; sanity may be defined as synthesis of insanities.”

57. “Envy consists in seeing things never in themselves, but only in their relations.”

58. “The most savage controversies are those about matters as to which there is no good evidence either way.”

59. “Most of the greatest evils that man has inflicted upon man have come through people feeling quite certain about something which, in fact, was false.”

60. “This illustrates an important truth, namely, that the worse your logic, the more interesting the consequences to which it gives rise.”

61. “The demand for certainty is one which is natural to man, but is nevertheless an intellectual vice.”

62. “No one ever gossips about the virtues of others.”

63. “A life too full of excitement is an exhausting life, in which continually stronger stimuli are needed to give the thrill that has come to be thought an essential part of pleasure.”

65. “If an opinion contrary to your own makes you angry, that is a sign that you are subconsciously aware of having no good reason for thinking as you do.”

66. “Official morality has always been oppressive and negative; it has said, ‘Thou shalt not,’ and has not troubled to investigate the effect of activities not forbidden by the code.”

67. “War grows out of ordinary human nature.”

68. “We need a morality based upon love of life, upon pleasure in growth, and positive achievement—not upon repression and prohibition.”

69. “Happiness is nonetheless true happiness because it must come to an end, nor do thought and love lose their value because they are not everlasting.”

70. “What has human happiness to do with morals? The object of morals is not to make people happy.”

71. “Human nature being what it is, people will insist upon getting some pleasure out of life.”

72. “One should, as a rule, respect public opinion in so far as is necessary to avoid starvation and to keep out of prison, but anything that goes beyond this is voluntary submission to an unnecessary tyranny, and is likely to interfere with happiness in all kinds of ways.”

73. “The secret of happiness is to face the fact that the world is horrible, horrible, horrible.”

74. “The secret of happiness is this: let your interest be as wide as possible and let your reactions to the things and persons who interest you be as far as possible friendly rather than hostile.”

75. “If there were in the world today any large number of people who desired their own happiness more than they desired the unhappiness of others, we could have paradise in a few years.”

76. “Anything you’re good at contributes to happiness.”

77. “To be without some of the things you want is an indispensable part of happiness.”

84. “The man who pursues happiness wisely will aim at the possession of a number of subsidiary interests in addition to those central ones upon which his life is built.”

85. “When you want to teach children to think, you begin by treating them seriously when they are little, giving them responsibilities, talking to them candidly, providing privacy and solitude for them, and making them readers and thinkers of significant thoughts from the beginning. That’s if you want to teach them to think.”

86. “We know very little, and yet it is astonishing that we know so much, and still more astonishing that so little knowledge can give us so much power.”

88. “So long as there is death, there will be sorrow, and so long as there is sorrow, it can be no part of the duty of human beings to increase its amount, in spite of the fact that a few rare spirits know how to transmute it.”

89. “In this world, which is getting more and more closely interconnected, we have to learn to tolerate each other, we have to learn to put up with the fact that some people say things that we don’t like. We can only live together in that way. But if we are to live together, and not die together, we must learn a kind of charity and a kind of tolerance, which is absolutely vital to the continuation of human life on this planet.”

I long to alleviate this evil, but I cannot, and I too suffer.”

149. “A sense of duty is useful in work, but offensive in personal relations. People wish to be liked, not to be endured with patient resignation.”

150. “It is not what the man of science believes that distinguishes him, but how and why he believes it. His beliefs are tentative, not dogmatic; they are based on evidence, not on authority or intuition.”

167. “Never let yourself be diverted, either by what you wish to believe, or what you think could have beneficent social effects if it were believed; but look only and solely at what are the facts.”
