It seems to me that I may be living too long. Indeed: my nearest relations have all died, and so have some of my best friends, and even some of my best pupils. However, I do not have a reason to complain. I am grateful and happy to be alive, and still be able to continue with my work, if only just. My work seems to me more important than ever.

I am using the word "perceive". I am using it here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word. If there is thought to be a difficulty here, it is perhaps because there is also a correct and familiar usage of the word "perceive", in which to say of an object that it is perceived does carry the implication that it exists.

That passivity was the essence of the problem. The human being was intended to be passive only in a condition of fatigue, and not always then. Too much passivity of body produced surplus fat, short-windedness, indigestion: passivity of mind produced the same symptoms on the mental level. a feeling of spiritual dyspepsia. Since the average human being has no purposes that are not connected with the activities of keeping alive, the black room was bound to produce passivity, increasing dullness, a state in which the mind is at once awake and static, motionless, stagnant. This sense of dullness was nothing less than the collapse of the sense of reality and of values, the retreat into one's inner world.

Plagued by Western habits of either-or, dualistic thinking, we all may fail to understand that race, class and gender interconnect to sustain a corporate ruling class. In the language of African-American essayist bell hooks, they are interlocking systems of oppression. Neither Latina nor Anglo women should yield to the temptation of making a hierarchy of oppressions where battles are fought over whether racism is "worse" than sexism, or class oppression is "deeper" than racism, etc. Instead of hierarchies we need bridges which, after all, exist to make two ends meet.

Neither a man nor a crowd nor a nation can be trusted to act humanely or to think sanely under the influence of a great fear.

We live invested in an electric information environment that is quite as imperceptible to us as water is to fish.

That the uneducated and the ill-educated should think the hypothesis that all races of beings, man inclusive, may in process of time have been evolved from the simplest monad, a ludicrous one, is not to be wondered at. But for the physiologist, who knows that every individual being is so evolved-who knows, further, that in their earliest condition the germs of all plants and animals whatever are so similar, "that there is no appreciable distinction amongst them, which would enable it to be determined whether a particular molecule is the germ of a Conferva or of an Oak, of a Zoophyte or of a Man";-for him to make a difficulty of the matter is inexcusable.

The way to true mysticism leads up through rational thought to deep experience of the world and of our will-to-live. We must all venture once more to be "thinkers," so as to reach mysticism, which is the only direct and the only profound world-view. We must all wander in the field of knowledge to the point where knowledge passes over into experience of the world. We must all, through thought, become religious.This rational thought must become the prevailing force among us, for all the valuable ideas that we need develop out of it. In no other fire than that of the mysticism of reverence for life can the broken sword of idealism be forged anew.

Great men, great nations, have not been boasters and buffoons, but perceivers of the terror of life, and have manned themselves to face it.

All men are in need of help and depend on one another. Human solidarity is the necessary condition for the unfolding of any one individual.

If it is permissible to write plays that are not intended to be seen, I should like to see who can prevent me from writing a book no one can read.

I like the dreams of the future better than the history of the past, - so good night!

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

If the brutes have consciousness and no souls, then it is clear that, in them, consciousness is a direct function of material changes; while, if they possess immaterial subjects of consciousness, or souls, then, as consciousness is brought into existence only as the consequence of molecular motion of the brain, it follows that it is an indirect product of material changes. The soul stands related to the body as the bell of a clock to the works, and consciousness answers to the sound which the bell gives out when it is struck.

The more one has suffered, the less one demands. To protest is a sign one has traversed no hell.

It is a serious question among them whether they [Africans] are descended from monkeys or whether the monkeys come from them. Our wise men have said that man was created in the image of God. Now here is a lovely image of the Divine Maker: a flat and black nose with little or hardly any intelligence. A time will doubtless come when these animals will know how to cultivate the land well, beautify their houses and gardens, and know the paths of the stars: one needs time for everything.

The Age that admires talk so much can have little discernment for inarticulate work, or for anything that is deep and genuine. Nobody, or hardly anybody, having in himself an earnest sense for truth, how can anybody recognize an inarticulate Veracity, or Nature-fact of any kind; a Human Doer especially, who is the most complex, profound, and inarticulate of all Nature's Facts? Nobody can recognize him: till once he is patented, get some public stamp of authenticity, and has been articulately proclaimed, and asserted to be a Doer. To the worshipper of talk, such a one is a sealed book. An excellent human soul, direct from Heaven,-how shall any excellence of man become recognizable to this unfortunate? Not except by announcing and placarding itself as excellent,-which, I reckon, it above other things will probably be in no great haste to do.

The spoken Word, the written Poem, is said to be an epitome of the man; how much more the done Work. Whatsoever of morality and of intelligence; what of patience, perseverance, faithfulness, of method, insight, ingenuity, energy; in a word, whatsoever of Strength the man had in him will lie written in the Work he does. To work: why, it is to try himself against Nature, and her everlasting unerring Laws; these will tell a true verdict as to the man.

The tangible source of exploitation disappears behind the façade of objective rationality.

In the 'Induction of Causes' the principal maxim is, that we must be careful to possess, and to apply, with perfect clearness, the Fundamental Idea on which the Induction depends. The Induction of Substance, of Force, of Polarity, go beyond mere laws of phenomena, and may be considered as the Induction cf Causes. The Cause of certain phenomena being inferred, we are led to inquire into the Cause of this Cause, which inquiry must be conducted in the same manner as the previous one; and thus we have the Induction of Ulterior Causes.

If the injustice is part of the necessary friction of the machine of government, let it go, let it go; perchance it will wear smooth--certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a crank, exclusively for itself, then perhaps you may consider whether the remedy will not be worse than the evil; but if it is of such a nature that it requires you to be the agent of injustice to another, then I say, break the law. Let your life be a counter-friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn.

The scene should be gently open'd, and his entrance made step by step, and the dangers pointed out that attend him from several degrees, tempers, designs, and clubs of men. He should be prepared to be shocked by some, and caress'd by others; warned who are like to oppose, who to mislead, who to undermine him, and who to serve him. He should be instructed how to know and distinguish them; where he should let them see, and when dissemble the knowledge of them and their aims and workings.

What I know at sixty, I knew as well at twenty. Forty years of a long, a superfluous, labor of verification.

All right, men are as they should be, can be. What should they be? Surely not more than they can be! And what can they be? Not more, again, than they - can, than they have the competence, the force, to be. But this they really are, because what they are not, they are incapable of being; for to be capable means - really to be. One is not capable for anything that one really is not; one is not capable of anything that one does not really do. Could a man blinded by cataract see? Oh, yes, if he had his cataract successfully removed. But now he cannot see because he does not see. Possibility and reality always coincide. One can do nothing that one does not, as one does nothing that one cannot.

There's nothing under the ground that's worthmore than the little layer of topsoil sitting on top of it.

With a few glorious and glaring exceptions, the shadow of Jim Crow was cast in its new glittering form expressed in the language of superficial diversity... The disarray of a scattered curriculum, the disenchantment of talented yet deferential faculty, and the disorientation of precious students loom large... To witness a faculty enthusiastically support a candidate for tenure then timidly defer to a rejection based on the Harvard administration's hostility to the Palestinian cause was disgusting... We all know the mendacious reasons given had nothing to do with academic standards... This kind of narcissistic academic professionalism, cowardly deference to the anti-Palestinian prejudices of the Harvard administration, and indifference to my Mother's death constitutes an intellectual and spiritual bankruptcy of deep deaths...

It is astounding that man, the instigator, inventor and vehicle of all these developments, the originator of all judgements and decisions and the planner of the future, must make himself such a quantité negligeable.

Scientists try to eliminate their false theories, they try to let them die in their stead. The believer-whether animal or man-perishes with his false beliefs.

The best university that can be recommended to a man of ideas is the gauntlet of the mobs.

Opinion is ultimately determined by the feelings, and not by the intellect.

Whoever asserts a value, must bring its influence to bear. Whoever maintains that it has value regardless of the influence brought to bear by any individual human being who endorses it, is simply cheating.

Do you suppose that God takes himself seriously? I know a Zen master, Joshu Sasaki, who has let it be known that the best form of meditation is to stand up with your hands on your hips and roar with laughter for ten minutes every morning. I have heard of a sophisticated shaman-type fellow who used to cure ringworm on cows just by pointing at the scars and laughing. Truly religious people always make jokes about their religion; their faith is so strong that they can afford it. Much of the secret of life consists in knowing how to laugh, and also how to breathe.

The human tendency to regard little things as important has produced very many great things. G 46 Variant translation: The inclination of people to consider small things as important has produced many great things.

Philosophy ... should not imagine that specialized work in epistemological theory, or whatever else prides itself on being research, is actually philosophy. Yet a philosophy forswearing all of that must in the end be irreconcilably at odds with the dominant consciousness. Nothing else raises it above the suspicion of apologetics. Philosophy that satisfies its own intention, and does not childishly skip behind its own history and the real one, has its lifeblood in the resistance against the common practices of today and what they serve, against the justification of what happens to be the case.

Just you think first, and don't bother to speak afterward, either.

They who know of no purer sources of truth, who have traced up its stream no higher, stand, and wisely stand, by the Bible and the Constitution, and drink at it there with reverence and humility; but they who behold where it comes trickling into this lake or that pool, gird up their loins once more, and continue their pilgrimage toward its fountain-head.

It is a sign of sovereignty to risk one's life, that is, to turn life into a game.

Forgiveness is the key to action and freedom.

People hate it when they're tickled because laughter is not pleasant, if it goes on too long. I think it's a desperate sort of convulsion in desperate circumstances, which helps a little.

The chief requirement of the good life... is to live without any image of oneself.

Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride or laziness of mind. 

If all men, by the act of being born, are destined to suffer violence, that is a truth to which the empire of circumstances closes their minds.

The "imagination that shudders at the Hell of Dante," is not that the same faculty, weaker in degree, as Dante's own? No one but Shakspeare can embody, out of Saxo Grammaticus, the story of Hamlet as Shakspeare did: but every one models some kind of story out of it; every one embodies it better or worse. We need not spend time in defining. Where there is no specific difference, as between round and square, all definition must be more or less arbitrary. A man that has so much more of the poetic element developed in him as to have become noticeable, will be called Poet by his neighbors.

We have no right to believe a thing true because everybody says so unless there are good grounds for believing that some one person at least has the means of knowing what is true, and is speaking the truth so far as he knows it. However many nations and generations of men are brought into the witness-box they cannot testify to anything which they do not know. Every man who has accepted the statement from somebody else, without himself testing and verifying it, is out of court; his word is worth nothing at all. And when we get back at last to the true birth and beginning of the statement, two serious questions must be disposed of in regard to him who first made it: was he mistaken in thinking that he knew about this matter, or was he lying?

In the temple of science are many mansions, and various indeed are they that dwell therein and the motives that have led them thither. Many take to science out of a joyful sense of superior intellectual power; science is their own special sport to which they look for vivid experience and the satisfaction of ambition; many others are to be found in the temple who have offered the products of their brains on this altar for purely utilitarian purposes. Were an angel of the Lord to come and drive all the people belonging to these two categories out of the temple, the assemblage would be seriously depleted, but there would still be some men, of both present and past times, left inside. Our Planck is one of them, and that is why we love him. I am quite aware that we have just now lightheartedly expelled in imagination many excellent men who are largely, perhaps chiefly, responsible for the buildings of the temple of science; and in many cases, our angel would find it a pretty ticklish job to decide. But of one thing I feel sure: if the types we have just expelled were the only types there were, the temple would never have come to be, any more than a forest can grow which consists of nothing but creepers. For these people any sphere of human activity will do if it comes to a point; whether they become engineers, officers, tradesmen, or scientists depends on circumstances.Now let us have another look at those who have found favor with the angel. Most of them are somewhat odd, uncommunicative, solitary fellows, really less like each other, in spite of these common characteristics, than the hosts of the rejected. What has brought them to the temple? That is a difficult question and no single answer will cover it.

It is the poets and painters who react instantly to a new medium like radio or TV.

To found a family. I think it would have been easier for me to found an empire.
