When Descartes said, "Conquer yourself rather than the world," what he meant was, at bottom, - the same - that we should act without hope. Marxists, to whom I have said thus have answered: "Your action is limited, obviously, by your death: but you can rely upon the help of others.

Buddhism is the most colossal example in the history of applied metaphysics.

The circumstances of justice may be described as the normal conditions under which human cooperation is both possible and necessary.

Arithmetic must be discovered in just the same sense in which Columbus discovered the West Indies, and we no more create numbers than he created the Indians.

An intellectual is a person who has discovered something more interesting than sex.

I do not want to found anything on the incomprehensible. I want to know whether I can live with what I know and with that alone.

It seems to me that, in every culture, I come across a chapter headed Wisdom. And then I know exactly what is going to follow: Vanity of vanities, all is vanity.

A person is strong only when he stands upon his own truth, when he speaks and acts from his deepest convictions. Then, whatever the situation he may be in, he always knows what he must say and do. He may fall, but he cannot bring shame upon himself or his cause. If we seek the liberation of the people by means of a lie, we will surely grow confused, go astray, and lose sight of our objective, and if we have any influence at all on the people we will lead them astray as well - in other words, we will be acting in the spirit of reaction and to its benefit.

We inherit the warlike type; and for most of the capacities of heroism that the human race is full of we have to thank this cruel history. Dead men tell no tales, and if there were any tribes of other type than this they have left no survivors. Our ancestors have bred pugnacity into our bone and marrow, and thousands of years of peace won't breed it out of us. The popular imagination fairly fattens on the thought of wars. Let public opinion once reach a certain fighting pitch, and no ruler can withstand it. In the Boer war both governments began with bluff, but they couldn't stay there; the military tension was too much for them.

We are not so absurd as to propose that the teacher should not set forth his own opinions as the true ones and exert his utmost powers to exhibit their truth in the strongest light. To abstain from this would be to nourish the worst intellectual habit of all, that of not finding, and not looking for, certainty in any teacher. But the teacher himself should not be held to any creed; nor should the question be whether his own opinions are the true ones, but whether he is well instructed in those of other people, and, in enforcing his own, states the arguments for all conflicting opinions fairly.

Orb webs in real life do their business largely in two dimensions. If the mesh is too coarse, flies pass straight through. If the mesh is too fine, rival spiders will achieve nearly the same result at less cost in silk, and will therefore leave behind more progeny to carry on their economically more prudent genes. Natural selection finds the efficient compromise.

Many, and I think the determining, constitutive facts remain outside the reach of the operational concept. And by virtue of this limitation-this methodological injunction against transitive concepts which might show the facts in their true light and call them by their true name-the descriptive analysis of the facts blocks the apprehension of facts and becomes an element of the ideology that sustains the facts. Proclaiming the existing social reality as its own norm, this sociology fortifies in the individuals the "faithless faith" in the reality whose victims they are.

In conclusion, then, no satisfactory interpretation of quantum mechanics exists today. The questions posed by the confrontation between the Copenhagen interpretation and the hidden variable theorists go to the very foundations of microphysics, but the answers given by hidden variable theorists and Copenhagenists are alike unsatisfactory. Human curiosity will not rest until those questions are answered, but whether they will be answered by conceptual innovations within the framework of the present theory or only within the framework of an as yet unforeseen theory is unknown. The first step toward answering them has been attempted here. It is the modest but essential step of becoming clear on the nature and magnitude of the difficulties.

If your brother sins against you, go and show him his fault, just between the two of you. If he listens to you, you have won your brother over.

All things living are in search of a better world.

If we cannot "practice the presence of God," it is something to practice the absence of God, to become increasingly aware of our unawareness till we feel like man who should stand beside a great cataract and hear no noise, or like a man in a story who looks in a mirror and finds no face there, or a man in a dream who stretches his hand to visible objects and gets no sensation of touch. To know that one is dreaming is to no longer be perfectly asleep. Bur for news of the fully waking world you must go to my betters.

Tell me how you want to die, and I'll tell you who you are.

I do feel that evolution is being controlled by some sort of divine engineer. I can't help thinking that. And this engineer knows exactly what he or she is doing and why, and where evolution is headed. That's why we've got giraffes and hippopotami and the clap.

If you are describing any occurrence... make two or more distinct reports at different times... We discriminate at first only a few features, and we need to reconsider our experience from many points of view and in various moods in order to perceive the whole.

Our whole civilization, our entire culture is concentrated in the mad demand for the most perfected weapons of slaughter. Ammunition! Ammunition! O, Lord, thou who rulest heaven and earth, thou God of love, of mercy and of justice, provide us with enough ammunition to destroy our enemy. Such is the prayer which is ascending daily to the Christian heaven.

How significant is the enormous heightening, under mescalin, of the perception of color! ... Man's highly developed color sense is a biological luxury-inestimably precious to him as an intellectual and spiritual being, but unnecessary to his survival as an animal. ... Mescalin raises all colors to a higher power and makes the percipient aware of innumerable fine shades of difference, to which, at ordinary times, he is completely blind. It would seem that, for Mind at Large, the so-called secondary characters of things are primary.

Some men are born committed to action: they do not have a choice, they have been thrown on a path, at the end of that path, an act awaits them, their act.

First then, we find that when we regard ideas from a nominalistic, individualistic, sensualistic way, the simplest facts of mind become utterly meaningless. That one idea should resemble another or influence another, or that one state of mind should so much as be thought of in another is, from that standpoint, sheer nonsense.

The mind advances only when it has the patience to go in circles, in other words, to deepen.

Do not ask who I am and do not ask me to remain the same: leave it to our bureaucrats and our police to see that our papers are in order. At least spare us their morality when we write.

What, by a word lacking even in grammar, is called amorality, is a thing that does not exist. If you are unwilling to submit to any norm, you have, nolens volens, to submit to the norm of denying all morality, and this is not amoral, but immoral. It is a negative morality which preserves the empty form of the other.

I urge you to please notice when you are happy, and exclaim or murmur or think at some point, "If this isn't nice, I don't know what is."

I am against a League war in present circumstances, because the anti-League powers are strong. The analogy is not King v. Barons, but the War of the Roses. If the League were strong enough I should favour sanctions, because the effect would suffice, or the war would be short and small. The whole question is quantitative.

Appealing to his [Einstein's] way of expressing himself in theological terms, I said: If God had wanted to put everything into the universe from the beginning, He would have created a universe without change, without organisms and evolution, and without man and man's experience of change. But he seems to have thought that a live universe with events unexpected even by Himself would be more interesting than a dead one.

"These Macedonians," said he, "are a rude and clownish people, that call a spade a spade."

The infinity of All ever bringing forth anew, and even as infinite space is around us, so is infinite potentiality, capacity, reception, malleability, matter.

Philosophy is like trying to open a safe with a combination lock: each little adjustment of the dials seems to achieve nothing, only when everything is in place does the door open.

Meditation on any theme, if positive and honest, inevitably separates him who does the meditating from the opinion prevailing around him, from that which ... can be called "public" or "popular" opinion.

For it is not the bare Words, but the Scope of the writer that giveth true light, by which any writing is to bee interpreted; and they that insist upon single Texts, without considering the main Designe, can derive no thing from them clearly; but rather by casting atomes of Scripture, as dust before mens eyes, make everything more obscure than it is; an ordinary artifice of those who seek not the truth, but their own advantage.

At the deepest level, the desire for complete union with God exhibits a narcissistic structure.

Lichtenberg ... held something of the following kind: one should neither affirm the existence of God nor deny it. ... It is not that he wished to leave certain perspectives open, nor to please everyone. It is rather that he was identifying himself, for his part, with a consciousness of self, of the world, and of others that was "strange" (the word is his) in a sense which is equally well destroyed by the rival explanations.

The chief danger to philosophy is narrowness in the selection of evidence.

In every stock-jobbing swindle everyone knows that some time or other the crash must come, but every one hopes that it may fall on the head of his neighbour, after he himself has caught the shower of gold and placed it in safety.

If, as I believe, the ends of men are many, and not all of them are in principle compatible with each other, then the possibility of conflict - and of tragedy - can never wholly be eliminated from human life, either personal or social. The necessity of choosing between absolute claims is then an inescapable characteristic of the human condition. This gives its value to freedom as Acton conceived of it - as an end in itself, and not as a temporary need, arising out of our confused notions and irrational and disordered lives, a predicament which a panacea could one day put right.

One of the ideas I had discussed in The Poverty of Historicism was the influence of a prediction upon the event predicted. I had called this the "Oedipus effect", because the oracle played a most important role in the sequence of events which led to the fulfilment of its prophecy. ... For a time I thought that the existence of the Oedipus effect distinguished the social from the natural sciences. But in biology, too-even in molecular biology-expectations often play a role in bringing about what has been expected.

The sham cause in physical influence consists in rashly assuming that the commerce of substance and transitive forces is sufficiently knowable from their mere existence. Hence it is not so much a system as rather the neglect of all philosophical system as a superfluity in the argument. Freeing the concept from this defect, we shall have a species of commerce alone deserving to be called real, and from which the whole constituting the world merits being called real, and not ideal or imaginary.

Philosophy is not politics, and we do our best, within our all-too-human limitations, to seek the truth, not to score points against opponents. There is little satisfaction in gaining an easy triumph over a weak opponent while ignoring better arguments against your views. 

There is a similarity between writers and SDS [Students for a Democratic Society, a radical left-wing group]: Plenty of paranoia, but no ideas.

What! the inventors of ancient civilisations, the first makers of tools and tape lines, the first builders of vehicles, ships, and houses, the first observers of the laws of the heavens and the multiplication tables is it contended that they were entirely different from the inventors and observers of our own time, and superior to them? And that the first slow steps forward were of a value which has not been equalled by the discoveries we have made with all our travels and circumnavigations of the earth?

Those who forget good and evil and seek only to know the facts are more likely to achieve good than those who view the world through the distorting medium of their own desires.

There are three successive states of morality answering to the three principal stages of human life; the personal, the domestic, and the social stage.

Not to be a proud and haughty person, you have to follow the old proverb and "know thyself." That is to say, you must regard your special talents, whatever beauty or fame you have, as gifts from God, and not as things you earned for yourself. Whatever is low and mean is not God's doing, however. Here you can only blame yourself. Remember the squalor of your birth and how naked and poor you were when you crawled into the light of day like a little animal.
