The significance of God, cause, number, substance or soul consists, as James asserts, in nothing but the tendency of the given concept to make us act or think. If the world should reach a point at which it ceases to care not only about such metaphysical entities but also about murders perpetrated behind closed frontiers or simply in the dark, one would have to conclude that the concepts of such murders have no meaning, that they represent no 'distinct ideas' or truths, since they do not make any 'sensible difference to anybody.

Who am I? Subject and object in one - contemplating and contemplated, thinking and thought of. As both must I have become what I am.

As for the life of money-making, it is one of constraint, and wealth is manifestly not the good of which we are in search, for it is only useful as a means to something else, and for this reason there is less to be said for it than for the ends mentioned before, which are, at any rate, desired for their own sakes.

...this Jewish doctrine of the primacy of economic values has found the widest acceptance and been most whole-heartedly acted upon. From America it has begun to infect the rest of the world. We may be pardoned for wishing that the Jews had remained not forty, but four thousand years in their repulsive wilderness.

Everyone must destroy their life. According to the way they do it, they're either triumphants or failures.

Everything is a subject on which there is not much to be said.

Philosophers often behave like little children who scribble some marks on a piece of paper at random and then ask the grown-up "What's that?" - It happened like this: the grown-up had drawn pictures for the child several times and said "this is a man," "this is a house," etc. And then the child makes some marks too and asks: what's this then?

There is probably no more abused a term in the history of philosophy than "representation," and my use of this term differs both from its use in traditional philosophy and from its use in contemporary cognitive psychology and artificial intelligence.... The sense of "representation" in question is meant to be entirely exhausted by the analogy with speech acts: the sense of "represent" in which a belief represents its conditions of satisfaction is the same sense in which a statement represents its conditions of satisfaction. To say that a belief is a representation is simply to say that it has a propositional content and a psychological mode.

The ambassador of Russia and the grandees who accompanied him were so gorgeous that all London crowded to stare at them, and so filthy that nobody dared to touch them. They came to the court balls dropping pearls and vermin.

If any philosopher had been asked for a definition of infinity, he might have produced some unintelligible rigmarole, but he would certainly not have been able to give a definition that had any meaning at all.

I read your piece on Plato. Holmes, when you strike at a king, you must kill him.

Everything in the universe goes by indirection. There are no straight lines.

I was walking late one night along a tree-lined path; a chestnut fell at my feet. The noise it made as it burst, the resonance it provoked in me, and an upheaval out of all proportion to this insignificant event thrust me into miracle, into the rapture of the definitive, as if there were no more questions - only answers. I was drunk on a thousand unexpected discoveries, none of which I could make use of. This is how I nearly reached the Supreme. But instead I went on with my walk.

The dream is the small hidden door in the deepest and most intimate sanctum of the soul, which opens to that primeval cosmic night that was soul long before there was conscious ego and will be soul far beyond what a conscious ego could ever reach.

So long as man is protected by madness he functions and flourishes, but when he frees himself from the fruitful tyranny of fixed ideas, he is lost, ruined.

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

Any plea ... for institutionalized risk-assessment, beefed-up bioethics panels, academic review bodies, worse-case scenario planning, more intensive computer simulations, systematic long-term planning and the institutionalized study of existential risks is admirable. But so is urgent action to combat the global pandemic of suffering. "The easiest pain to bear is someone else's"

I would rather be a poor man in a garret with plenty of books than a king who did not love reading.

The mental operation by which one achieves new concepts and which one denotes generally by the inadequate name of induction is not a simple but rather a very complicated process. Above all, it is not a logical process although such processes can be inserted as intermediary and auxiliary links. The principle effort that leads to the discovery of new knowledge is due to abstraction and imagination.

There is, properly speaking, no Misfortune in the world. Happiness and Misfortune stand in continual balance. Every Misfortune is, as it were, the obstruction of a stream, which, after overcoming this obstruction, but bursts through with the greater force.

Respectable scientists like de Broglie himself accept wave mechanics because it confers coherence and unity upon the experimental findings of contemporary science, and in spite of the astonishing changes it implies in connection with ideas of causality, time, and space, but it is because of these changes that it wins favor with the public. The great popular success of Einstein was the same thing. The public drinks in and swallows eagerly everything that tends to dispossess the intelligence in favor of some technique; it can hardly wait to abdicate from intelligence and reason and from everything that makes man responsible for his destiny.

Often must you turn your pencil to erase, if you hope to write something worth a second reading.

This disposition to admire, and almost to worship, the rich and powerful, and to despise or, at least, neglect persons of poor and mean conditions, though necessary both to establish and to maintain the distinction of ranks and the order of society, is, at the same time, the great and most universal cause of the corruption of our moral sentiments.

Attempt nothing above thy strength!

A happy and eternal being has no trouble himself and brings no trouble upon any other being; hence he is exempt from movements of anger and partiality, for every such movement implies weakness.

Station, power, wealth-how inadequate they have proved! How useless and insecure!

Just as eunuchs will never know aesthetics as applied to the selection of beautiful women, so neither will pure rationalists ever know ethics, nor will they ever succeed in defining happiness, for happiness is a thing that is lived and felt, not a thing that is reasoned or defined.

Denotation by means of sounds and markings is a remarkable abstraction. Three letters designate God for me; several lines a million things. How easy becomes the manipulation of the universe here, how evident the concentration of the intellectual world! Language is the dynamics of the spiritual realm. One word of command moves armies; the word Liberty entire nations.

Wit is cultured insolence.

We are always on stage, even when we are stabbed in earnest at the end.

... a penny saved is better than a penny earned.

Power is never naked. Rather, it is eloquent.

If one assumes, as I do, that battery is caused by the belief permeating this culture that hierarchical rule and coercive authority are natural, then all our relationships tend to be based on power and domination, and thus all forms of battery are linked.

No man is free who is not master of himself.

To claim you are more detached, more alien to everything than anyone, and to be merely a fanatic of indifference!

When you know quite absolutely that everything is unreal, you then cannot see why you should take the trouble to prove it.

Most men's conscience, habits, and opinions are borrowed from convention and gather continual comforting assurances from the same social consensus that originally suggested them.

Everywhere we remain unfree and chained to technology, whether we passionately affirm or deny it. But we are delivered over to it in the worst possible way when we regard it as something neutral; for this conception of it, to which today we particularly like to do homage, makes us utterly blind to the essence of technology.

Men looke not at the greatnesse of the evill past, but the greatnesse of the good to follow.

Despotic government supports itself by abject civilization, in which debasement of the human mind, and wretchedness in the mass of the people, are the chief criterions. Such governments consider man merely as an animal; that the exercise of intellectual faculty is not his privilege; that he has nothing to do with the laws but to obey them; and they politically depend more upon breaking the spirit of the people by poverty, than they fear enraging it by desperation.

Suppose ye that I am come to give peace on earth? I tell you, Nay; but rather division: For from henceforth there shall be five in one house divided, three against two, and two against three. The father shall be divided against the son, and the son against the father; the mother against the daughter, and the daughter against the mother; the mother in law against her daughter in law, and the daughter in law against her mother in law. And he said also to the people, When ye see a cloud rise out of the west, straightway ye say, There cometh a shower; and so it is. And when ye see the south wind blow, ye say, There will be heat; and it cometh to pass. Ye hypocrites, ye can discern the face of the sky and of the earth; but how is it that ye do not discern this time? Yea, and why even of yourselves judge ye not what is right?

The greatest height of heroism to which an individual, like a people, can attain is to know how to face ridicule; better still, to know how to make oneself ridiculous and not to shrink from the ridicule.

People never remember but the computer never forgets.

Any man more right than his neighbors constitutes a majority of one.

The essential nature (concerning the soul) cannot be corporeal, yet it is also clear that this soul is present in a particular bodily part, and this one of the parts having control over the rest (heart).

A people represents not so much an aggregate of ideas and theories as of obsessions.

Prejudices are so to speak the mechanical instincts of men: through their prejudices they do without any effort many things they would find too difficult to think through to the point of resolving to do them.

[My father] impressed upon me from the first, that the manner in which the world came into existence was a subject on which nothing was known: that the question, "Who made me?" cannot be answered, because we have no experience or authentic information from which to answer it; and that any answer only throws the difficulty a step further back, since the question immediately presents itself, "Who made God?"
