After Riemann had made known his discoveries, mathematicians busied themselves with working out his system of geometrical ideas formally; chief among these were Christoffel, Ricci, and Levi-Civita. Riemann... clearly left the real development of his ideas in the hands of some subsequent scientist whose genius as a physicist could rise to equal flights with his own as a mathematician. After a lapse of seventy years this mission has been fulfilled by Einstein.

Let what will be said or done, preserve your sang-froid immovably, and to every obstacle, oppose patience, perseverance, and soothing language.

To this day, and in quarters where they should know better, Darwinism is widely regarded as a theory of 'chance'.It is grindingly, creakingly, crashingly obvious that, if Darwinism were really a theory of chance, it couldn't work. You don't need to be a mathematician or physicist to calculate that an eye or a haemoglobin molecule would take from here to infinity to self-assemble by sheer higgledy-piggledy luck. Far from being a difficulty peculiar to Darwinism, the astronomic improbability of eyes and knees, enzymes and elbow joints and the other living wonders is precisely the problem that any theory of life must solve, and that Darwinism uniquely does solve.

Artistic creation is a demand for unity and a rejection of the world.

In America I was liberated from a certain naïve belief in culture and attained the capacity to see culture from the outside. To clarify the point: in spite of all social criticism and all consciousness of the primacy of economic factors, the fundamental importance of the mind-"Geist"-was quasi a dogma self-evident to me from the very beginning. The fact that this was not a foregone conclusion, I learned in America, where no reverential silence in the presence of everything intellectual prevailed.

Burden not the back of Aries, Leo, or Taurus, with thy faults, nor make Saturn, Mars, or Venus, guilty of thy Follies.

For in every country of the world, I believe, the avarice and injustice of princes and sovereign states, abusing the confidence of their subjects, have by degrees diminished the real quantity of metal, which had been originally contained in their coins.

Arms observe no bounds; nor can the wrath of the sword, once drawn, be easily checked or stayed; war delights in blood.

This world is empty to him alone who does not understand how to direct his libido towards objects, and to render them alive and beautiful for himself, for Beauty does not indeed lie in things, but in the feeling that we give to them.

In brief, it is my thesis that human misery is the most urgent problem of a rational public policy and that happiness is not such a problem.

An intuitionist conception of justice is, one might say, but half a conception.

Let no man be ashamed to speak what he is not ashamed to think.

Every living creature is happy when he fulfills his destiny, that is, when he realizes himself, when he is being that which in truth he is. For this reason, Schlegel, inverting the relationship between pleasure and destiny, said, "We have a genius for what we like." Genius, man's superlative gift for doing something, always carries a look of supreme pleasure.

If a victory is told in detail, one can no longer distinguish it from a defeat.

Loren von Stein thus turned the dialectic into an ensemble of objective laws calling for social reform as the adequate solution of all contradictions and neutralized the critical elements of the dialectic.

A Roman emperor sitting at the table surrounded by his bodyguard is a magnificent sight, but when the reason is fear, the magnificence pales. So also when the individual does not dare stand taciturnly by his word, does not stand freely and confidently on the pedestal of a conscious act, but is surrounded by a host of deliberations before and after that render him incapable of getting his eye on the action.

See now the power of truth; the same experiment which at first glance seemed to show one thing, when more carefully examined, assures us of the contrary.

In the practical use of our intellect, forgetting is as important a function as recollecting.

For what is life but a play in which everyone acts a part until the curtain comes down?

As if to demonstrate, by a striking example, the impossibility of erecting any cerebral barrier between man and the apes, Nature has provided us, in the latter animals, with an almost complete series of gradations from brains little higher than that of a Rodent, to brains little lower than that of Man.

For a thinking man is where Wisdom is at home.

Number is the ruler of forms and ideas, and the cause of gods and daemons.

The difference between a Humanist and a lunatic is in fact one of degree.

With exceptions so rare they are regarded as miracles of nature, successful democratic politicians are insecure and intimidated men. They advance politically only as they placate, appease, bribe, seduce, bamboozle, or otherwise manage to manipulate the demanding and threatening elements in their constituencies. The decisive consideration is not whether the proposition is good but whether it is popular-not whether it will work well and prove itself but whether the active talking constituents like it immediately. Politicians rationalize this servitude by saying that in a democracy public men are the servants of the people.

The mechanical mind has a passion for control - of everything except itself. Beyond the control it has won over the forces of nature it would now win control over the forces of society of stating the problem and producing the solution, with social machinery to correspond.

And in these foure things, Opinion of Ghosts, Ignorance of second causes, Devotion towards what men fear, and Taking of things Casuall for Prognostics, consisteth the Natural seed of Religion; which by reason of the different Fancies, Judgements, and Passions of severall men, hath grown up into ceremonies so different, that those which are used by one man, are for the most part ridiculous to another.

We have ...as M. Ribot says, not memory so much as memories. The visual... tactile... muscular... auditory memory may all vary independently... and different individuals may have them developed in different degrees. As a rule, a man's memory is good in the departments in which his interest is strong; but those departments are apt to be those in which his discriminative sensibility is high. ...[D]ifferences in men's imagining power... the machinery of memory must be largely determined thereby.

The longest-lived and the shortest-lived man, when they come to die, lose one and the same thing.

We will freedom for freedom's sake, in and through particular circumstances. And in thus willing freedom, we discover that it depends entirely upon the freedom of others and that the freedom of others depends upon our own. Obviously, freedom as the definition of a man does not depend upon others, but as soon as there is a commitment, I am obliged to will the liberty of others at the same time as my own. I cannot make liberty my aim unless I make that of others equally my aim.

As soon as we cease to believe in such an engineer and in a discourse which breaks with the received historical discourse, and as soon as we admit that every finite discourse is bound by a certain bricolage and that the engineer and the scientist are also species of bricoleurs, then the very idea of bricolage is menaced and the difference in which it took on its meaning breaks down.

The revolutionary and critical thinker is in a certain way always outside of his society while of course he is at the same time also in it. That he is in it is obvious, but why is he outside it? First, because he is not brainwashed by the ruling ideology, that is to say, he has an extraordinary kind of independence of thought and feeling; hence he can have a greater objectivity than the average person has. There are many emotional factors too. And certainly I do not mean to enter here into the complex problem of the revolutionary thinker. But it seems to me essential that in a certain sense he transcends his society. You may say he transcends it because of the new historical developments and possibilities he is aware of, while the majority still think in traditional terms.

Only thoughts that are randomly born die. The other thoughts we carry with us without knowing them. They have abandoned themselves to forgetfulness so that they can be with us all the time.

Love one another. My final lesson of history is the same as that of Jesus. You may think that's a lot of lollipop but just try it. Love is the most practical thing in the world. If you take an attitude of love toward everybody you meet, you'll eventually get along. When asked, at the age of 92, if he could summarize the lessons of history into a single sentence.

On recent and contemporary literature student's need is least and our help least. They ought to understand it better than we, and if they do not then there is something radically wrong either with them or with the literature. But I need not labour the point. There is an intrinsic absurdity in making current literature a subject of academic study, and the student who wants a tutor's assistance in reading the works of his own contemporaries might as well ask for a nurse's assistance in blowing his own nose.

Each of us is born with a share of purity, predestined to be corrupted by our commerce with mankind, by that sin against solitude.

Your crystal? That's silly. Whom do you think you are fooling? Come on, everyone knows that I threw the baby out of the window. The crystal is shattered on earth, and I do not care. I am no longer anything but a skin, and my skin does not belong to you.

Certainly no nation ever before abandoned to the avarice and jugglings of private individuals to regulate according to their own interests, the quantum of circulating medium for the nation - to inflate, by deluges of paper, the nominal prices of property, and then to buy up that property at 1s. in the pound, having first withdrawn the floating medium which might endanger a competition in purchase. Yet this is what has been done, and will be done, unless stayed by the protecting hand of the legislature. The evil has been produced by the error of their sanction of this ruinous machinery of banks; and justice, wisdom, duty, all require that they should interpose and arrest it before the schemes of plunder and spoliation desolate the country.

The chief error in philosophy is overstatement.

Now, what is 'unrighteousness' in practice? It is in practice behavior of a kind disliked by the herd. By calling it unrighteousness, and by arranging an elaborate system of ethics around this conception, the herd justifies itself in wreaking punishment upon the objects of its own dislike, while at the same time, since the herd is righteous by definition, it enhances its own self-esteem at the very moment when it lets loose its impulse to cruelty. This is the psychology of lynching, and of the other ways in which criminals are punished. The essence of the conception of righteousness, therefore, is to afford an outlet for sadism by cloaking cruelty as justice.

The characteristic of the hour is that the commonplace mind, knowing itself to be commonplace, has the assurance to proclaim the rights of the commonplace and to impose them wherever it will. As they say in the United States: "to be different is to be indecent." The mass crushes beneath it everything that is different, everything that is excellent, individual, qualified and select. Anybody who is not like everybody, who does not think like everybody, runs the risk of being eliminated. And it is clear, of course, that this "everybody" is not "everybody." "Everybody" was normally the complex unity of the mass and the divergent, specialised minorities. Nowadays, "everybody" is the mass alone.

The will to the "true world" in the sense of Plato and Christianity ... is in truth a no-saying to our present world, precisely the one in which art is at home.

The family uses people, not for what they are, nor for what they are intended to be, but for what it wants them for - its own uses. It thinks of them not as what God has made them, but as the something which it has arranged that they shall be.

What we should be after death, we have to attain in life, i.e. holiness and bliss. Here on earth the Kingdom of God begins.

In the course of instruction which I have partially retraced, the point most superficially apparent is the great effort to give, during the years of childhood an amount of knowledge in what are considered the higher branches of education, which is seldom acquired (if acquired at all) until the age of manhood.

When I hear any man talk of an unalterable law, the only effect it produces upon me is to convince me that he is an unalterable fool.

One reason an egalitarian approach to the value of life is important is that it draws from ideals of radical democracy at the same time that it enters into ethical considerations about how best to practice nonviolence. The institutional life of violence will not be brought down by a prohibition, but only by a counter-institutional ethos and practice.

One does not discover the absurd without being tempted to write a manual of happiness. "What! — by such narrow ways — ?" There is but one world, however. Happiness and the absurd are two sons of the same earth. They are inseparable. It would be a mistake to say that happiness necessarily springs from the absurd discovery. It happens as well that the feeling of the absurd springs from happiness.
