Now civilizations, I believe, come to birth and proceed to grow by successfully responding to successive challenges. They break down and go to pieces if and when a challenge confronts them which they fail to meet.

Every political good carried to the extreme must be productive of evil.

A series of accidents creates a positively lighthearted state.

As a scholar [Allan Bloom] intends to enlighten us, and as a writer he has learned from Aristophanes and other models that enlightenment should also be enjoyable. To me, this is not the book of a professor, but that of a thinker who is willing to take the risks more frequently taken by writers. It is risky in a book of ideas to speak in one's own voice, but it reminds us that the sources of the truest truths are inevitably profoundly personal. ... Academics, even those describing themselves as existentialists, very seldom offer themselves publicly and frankly as individuals, as persons.

The revolution in scientific ideas just mentioned is primarily logical. It is due to recognition that the very method of physical science, with its primary standard units of mass, space, and time, is concerned with measurements of relations of change, not with individuals as such.

Let sanguine healthy-mindedness do its best with its strange power of living in the moment and ignoring and forgetting, still the evil background is really there to be thought of, and the skull will grin in at the banquet.

Life is that which can hold a purpose for three thousand years and never yield. The individual fails, but life succeeds. The individual is foolish, but life holds in its blood and seed the wisdom of generations. The individual dies, but life, tireless and undiscourageble, goes on, wondering, longing, planning, trying, mounting, longing.

In speaking of sociological laws or natural laws of social life I have in mind such laws as are formulated by modern economic theories, for instance, the theory of international trade, or the theory of the trade cycle. These and other important sociological laws are connected with the functioning of social institutions. These laws play a role in our social life corresponding to the role played in mechanical engineering by, say, the principle of the lever. For institutions, like levers, are needed if we want to achieve anything which goes beyond the power of our muscles. Like machines, institutions multiply our power for good or evil. Like machines, they need intelligent supervision by someone who understands their way of functioning and, most of all, their purpose, since we cannot build them so that they work entirely automatically.

To be good and lead a good life means to give to others more than one takes from them.

Both Stoicism and Epicureanism - the apathetic acceptance of defeat, and the effort to forget defeat in the arms of pleasure - were theories as to how one might yet be happy though subjugated or enslaved; precisely as the stoicism of Schopenhauer and the despondent epicureanism of Renan were in the nineteenth century the symbols of a shattered revolution and a broken France.

One capitalist always kills many.

We know very well that we are only allowed to go on eating our dinner, to finish seeing the new play, or to enjoy to the end the ball, the Christmas fete, the promenade, the races or, the hunt, thanks to the policeman's revolver or the soldier's rifle, which will shoot down the famished outcast who has been robbed of his share, and who looks round the corner with covetous eyes at our pleasures, ready to interrupt them instantly, were not policeman and soldier there prepared to run up at our first call for help.

You must read Plato. But you must hold him at arm's length and say, 'Plato, you have delighted and edified mankind for two thousand years. What have you to say to me?'

Half of the human race lives in manifest obedience to the lunar rhythm; and there is evidence to show that the psychological and therefore the spiritual life, not only of women, but of men too, mysteriously ebbs and flows with the changes of the moon. There are unreasoned joys, inexplicable miseries, laughters and remorses without a cause. Their sudden and fantastic alternations constitute the ordinary weather of our minds. These moods, of which the more gravely numinous may be hypostasized as gods, the lighter, if we will, as hobgoblins and fairies, are the children of the blood and humours. But the blood and humours obey, among many other masters, the changing moon. Touching the soul directly through the eyes and, indirectly, along the dark channels of the blood, the moon is doubly a divinity.

I react like everyone else, even like those I most despise; but I make up for it by deploring every action I commit, good or bad.

The militarily-patriotic and the romantic-minded everywhere, and especially the professional military class, refuse to admit for a moment that war may be a transitory phenomenon in social evolution. The notion of a sheep's paradise like that revolts, they say, our higher imagination. Where then would be the steeps of life? If war had ever stopped, we should have to re-invent it, on this view, to redeem life from flat degeneration. Reflective apologists for war at the present day all take it religiously. It is a sort of sacrament. It's profits are to the vanquished as well as to the victor; and quite apart from any question of profit, it is an absolute good, we are told, for it is human nature at its highest dynamic.

To spare the guilty is to injure the innocent.

Do you think that I count the days? There is only one day left, always starting over: it is given to us at dawn and taken away from us at dusk.

The subversive character of truth inflicts upon thought an imperative quality. Logic centers on judgments which are, as demonstrative propositions, imperatives, - the predicative "is" implies an "ought." ... Verification of the proposition involves a process in fact as well as in thought: (S) must become that which it is. The categorical statement thus turns into a categorical imperative; it does not state a fact but the necessity to bring about a fact. For example, it could be read as follows: man is not (in fact) free, endowed with inalienable rights, etc., but he ought to be.

Socrates reminds us that it is not the same thing, but almost the opposite, to understand religion and to accept it.

When communist workmen associate with one another, theory, propaganda, etc., is their first end. But at the same time, as a result of this association, they acquire a new need - the need for society - and what appears as a means becomes an end. You can observe this practical processing its most splendid results whenever you see French socialist workers together. Such things as smoking, drinking, eating, etc., are no longer means of contact or means that bring together. Company, association, and conversation, which again has society as its end, are enough for them; the brotherhood of man is on mere phase with them, but a fact of life, and the nobility of man shines upon us from their work-hardened bodies.

A race preserves its vigour so long as it harbours a real contrast between what has been and what may be, and so long as it is nerved by the vigour to adventure beyond the safeties of the past. Without adventure, civilization is in full decay.

[T]he first philosophers, in investigating the truth and the nature of things, wandered, as if led by ignorance, into a certain... path. Hence, they say that no being is either generated or corrupted, because it is necessary that what is generated should be generated either from being or non-being: but both these are impossible; for neither can being be generated, since it already is; and from nothing, nothing can be generated... And thus... they said that there were not many things, but that being alone had a subsistence. ...the ancient philosophers ...through this ignorance added so much to their want of knowledge, as to fancy that nothing else was generated or had a being; but they subverted all generation.

Life itself is always pulling you away from the understanding of life.

Nothing is terrible except fear itself.

Not only does the action of Governments not deter men from crimes; on the contrary, it increases crime by always disturbing and lowering the moral standard of society. Nor can this be otherwise, since always and everywhere a Government, by its very nature, must put in the place of the highest, eternal, religious law (not written in books but in the hearts of men, and binding on every one) its own unjust, man-made laws, the object of which is neither justice nor the common good of all but various considerations of home and foreign expediency.

Pure mathematics is religion.

The judges of normality are present everywhere. We are in the society of the teacher-judge, the doctor-judge, the educator-judge, the social worker-judge; it is on them that the universal reign of the normative is based; and each individual, wherever he may find himself, subjects to it his body, his gestures, his behavior, his aptitudes, his achievements.

It is a most earnest thing to be alive in this world; to die is not sport for a man. Man's life never was a sport to him; it was a stern reality, altogether a serious matter to be alive!

I know of nothing more terrible than the poor creatures who have learned too much. Instead of the sound powerful judgement which would probably have grown up if they had learned nothing, their thoughts creep timidly and hypnotically after words, principles and formulae, constantly by the same paths. What they have acquired is a spider's web of thoughts too weak to furnish sure supports, but complicated enough to provide confusion.

Perhaps there is nobody who would sacrifice his life for the sake of maintaining that the three angles of a triangle are together equal to two right angles, for such a truth does not demand the sacrifice of our life; but, on the other hand, there are many who have lost their lives for the sake of maintaining their religious faith. Indeed, it is truer to say that martyrs make faith than that faith makes martyrs. For faith is not the mere adherence of the intellect to an abstract principle; it is not the recognition of a theoretical truth, the process in which the will merely sets in motion our faculty of comprehension; faith is an act of the will - it is a movement of the soul towards a practical truth, towards a person, towards something that makes us not merely comprehend life, but that makes us live.

Just because emotion is essential to that act of expression which produces a work of art, it is easy for inaccurate analysis to misconceive its mode of operation and conclude that the work of art has emotion for its significant content. One may cry out with joy or even weep upon seeing a friend from whom one has been long separated. The outcome is not an expressive object -- save to the onlooker. But if the emotion leads one to gather material that is affiliated to the mood which is aroused, a poem may result. In the direct outburst, an objective situation is the stimulus, the cause, of the emotion. In the poem, objective material becomes the content and matter of the emotion, not just its evocative occasion.

Those only are happy (I thought) who have their minds fixed on some object other than their own happiness; on the happiness of others, on the improvement of mankind, even on some art or pursuit, followed not as a means, but as itself an ideal end. Aiming thus at something else, they find happiness by the way.

I have never seen a class so deeply demoralised, so incurably debased by selfishness, so corroded within, so incapable of progress, as the English bourgeoisie; and I mean by this, especially the bourgeoisie proper, particularly the Liberal, Corn Law repealing bourgeoisie. For it nothing exists in this world, except for the sake of money, itself not excluded. It knows no bliss save that of rapid gain, no pain save that of losing gold. In the presence of this avarice and lust of gain, it is not possible for a single human sentiment or opinion to remain untainted.

I appeal to the philosophers of all countries to unite and never again mention Heidegger or talk to another philosopher who defends Heidegger. This man was a devil. I mean, he behaved like a devil to his beloved teacher, and he has a devilish influence on Germany. ... One has to read Heidegger in the original to see what a swindler he was.

Out from the heart of Nature rolled The burdens of the Bible old.

The seeing eye! It is this that discloses the inner harmony of things; what Nature meant, what musical idea Nature has wrapped up in these often rough embodiments. Something she did mean. To the seeing eye that something were discernible. Are they base, miserable things? You can laugh over them, you can weep over them; you can in some way or other genially relate yourself to them; - you can, at lowest, hold your peace about them, turn away your own and others' face from them, till the hour come for practically exterminating and extinguishing them!

Preserving seeks to secure the life that already is; safeguarding secures and reproduces the conditions of becoming, of living, of futurity, where the content of that life, that living, can be neither prescribed nor predicted, and where self-determination emerges as a potential.

The Churches as Churches have always been and cannot fail to be institutions not only alien to, but directly hostile towards, Christ's teaching.

You are a little soul carrying a corpse around, as Epictetus used to say.

Lord, give me the capacity of never praying, spare me the insanity of all worship, let this temptation of love pass from me which would deliver me forever unto You. Let the void spread between my heart and heaven! I have no desire to people my deserts by Your presence, to tyrannize my nights by Your light, to dissolve my Siberias beneath Your sun.

The supporters of the Development Hypothesis... can show that any existing species-animal or vegetable-when placed under conditions different from its previous ones, immediately begins to undergo certain changes fitting it for the new conditions. They can show that in successive generations these changes continue; until, ultimately, the new conditions become the natural ones. They can show that in cultivated plants, in domesticated animals, and in the several races of men, such alterations have taken place. They can show that the degrees of difference so produced are often, as in dogs, greater than those on which distinctions of species are in other cases founded.

Why do I think that we, the intellectuals, are able to help? Simply because we, the intellectuals, have done the most terrible harm for thousands of years. Mass murder in the name of an idea, a doctrine, a theory, a religion - that is all our doing, our invention: the invention of the intellectuals. If only we would stop setting man against man - often with the best intentions - much would be gained. Nobody can say that it is impossible for us to stop doing this.

As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power. You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about.

"They are slaves," people declare. Nay, rather they are men. "Slaves!" No, comrades. "Slaves!" No, they are unpretentious friends. "Slaves!" No, they are our fellow-slaves, if one reflects that Fortune has equal rights over slaves and free men alike.

I am much more open about categories of gender, and my feminism has been about women's safety from violence, increased literacy, decreased poverty and more equality. I was never against the category of men. "As a Jew, I was taught it was ethically imperative to speak up" in Haaretz.

Perhaps its destruction has been brought about only that it may be raised up again to a better destiny. Oftentimes a reverse has but made room for more prosperous fortune. Many structures have fallen only to rise to a greater height.
