Nothing seems at first sight less important than the outward form of human actions, yet there is nothing upon which men set more store: they grow used to everything except to living in a society which has not their own manners.

I feel that the entire spiritual life consists in this: That we gradually turn from those things whose appearance is deceptive to those things that are real.

The soul was not made to dwell in a thing; and when forced to it, there is no part of that soul but suffers violence.

And seeing every man is presumed to do all things in order to his own benefit, no man is a fit Arbitrator in his own cause.

It is a great force, and a great fortune, to be able to live without any ambition whatever. I aspire to it, but the very fact of so aspiring still participates in ambition.

There is thus a certain plausibility to Nietzsche's doctrine, though it is dynamite. He maintains in effect that the gulf separating Plato from the average man is greater than the cleft between the average man and a chimpanzee.

Ever from one who comes to-morrow Men wait their good and truth to borrow.

Science doesn't purvey absolute truth. Science is a mechanism. It's a way of trying to improve your knowledge of nature. It's a system for testing your thoughts against the universe and seeing whether they match. And this works, not just for the ordinary aspects of science, but for all of life. I should think people would want to know that what they know is truly what the universe is like, or at least as close as they can get to it.

The hazards of the generalized prisoner's dilemma are removed by the match between the right and the good.

Is the position tenable, that certain phenomena, possible in Euclidean space, would be impossible in non-Euclidean space, so that experience, in establishing these phenomena, would directly contradict the non-Euclidean hypothesis? For my part I think no such question can be put. To my mind it is precisely equivalent to the following, whose absurdity is patent to all eyes: are there lengths expressible in meters and centimeters, but which can not be measured in fathoms, feet, and inches, so that experience, in ascertaining the existence of these lengths, would directly contradict the hypothesis that there are fathoms divided into six feet?

Between the Shaman of the Tungus, the European prelate who rules church and state, the Voguls, and the Puritans, on the one hand, and the man who listens to his own command of duty, on the other, the difference is not that the former make themselves slaves, while the latter is free, but that the former have their lord outside themselves, while the latter carries his lord in himself, yet at the same time is his own slave.

It is not how things are in the world that is mystical, but that it exists.

The real and effectual discipline which is exercised over a workman is that of his customers. It is the fear of losing their employment which restrains his frauds and corrects his negligence.

The death of Alexander (323 BC) quickened this process of decay. The boy-emperor, barbarian though he remained after all of Aristotle's tutoring, had yet learned to revere the rich culture of Greece, and had dreamed of spreading that culture through the Orient in the wake of his victorious armies.... But he had underrated the inertia and resistance of the Oriental mind, and the mass and depth of Oriental culture. It was only a youthful fancy, after all, to suppose that so immature and unstable a civilization as that of Greece could be imposed upon a civilization immeasurably more widespread, and rooted in the most venerable traditions. The quantity of Asia proved too much for the quality of Greece.

But though there be naturally a wide difference in point of delicacy between one person and another, nothing tends further to encrease and improve this talent, than practice in a particular art, and the frequent survey or contemplation of a particular species of beauty.

Through all of history and pre-history it has been accepted that there is something wrong with the human animal. Health may be the natural condition of other species, but in humans it is sickness that is normal. To be chronically unwell is part of what it means to be human. It is no accident that every culture has its own versions of therapy. Tribal shamans and modern psychotherapists answer the same needs and practise the same trade.

To this end they make a shield of their hypocritical zeal for religion. They go about invoking the Bible, which they would have minister to their deceitful purposes. Contrary to the sense of the Bible and the intention of the holy Fathers, if I am not mistaken, they would extend such authorities until even in purely physical matters - where faith is not involved - they would have us altogether abandon reason and the evidence of our senses in favor of some biblical passage, though under the surface meaning of its words this passage may contain a different sense.

As Narcissus fell in love with an outering (projection, extension) of himself, man seems invariably to fall in love with the newest gadget or gimmick that is merely an extension of his own body.

It is the worst of all quaint and of all cheap ways of life that they bring us at last to the pinch of some humiliation.

It is an advantage to all narrow wisdom and narrow morals that their maxims have a plausible air; and, on a cursory view, appear equal to first principles. They are light and portable. They are as current as copper coin; and about as valuable. They serve equally the first capacities and the lowest; and they are, at least, as useful to the worst men as to the best. Of this stamp is the cant of not man, but measures; a sort of charm by which many people get loose from every honourable engagement.

A book can never be anything more than the impression of its author's thoughts [Ein Buch kann nie mehr seyn, als der Abdruck der Gedanken des Verfassers]. The value of these thoughts lies either in the matter about which he has thought, or in the form in which he develops his matter - that is to say, what he has thought about it.

It is no more evident that democratic institutions are to be measured by the sort of person they create than that they are to be measured against divine commands. ... Even if the typical character types of liberal democracies are bland, calculating, petty, and unheroic, the prevalence of such people may be a reasonable price to pay for political freedom.

What a stupendous, what an incomprehensible machine is man! Who can endure toil, famine, stripes, imprisonment and death itself in vindication of his own liberty, and the next moment, be deaf to all those motives whose powers supported him through his trial, and inflict on his fellow men a bondage, one hour of which is fraught with more misery than ages of that which he rose in rebellion to oppose.

It was in the reign of Charles II that they obtained the noble distinction of being exempted from giving their testimony on oath in a court of justice, and being believed on their bare affirmation. On this occasion the chancellor, who was a man of wit, spoke to them as follows: "Friends, Jupiter one day ordered that all the beasts of burden should repair to be shod. The asses represented that their laws would not allow them to submit to that operation. 'Very well,' said Jupiter; 'then you shall not be shod; but the first false step you make, you may depend upon being severely drubbed.'"

You worry whether the drought will end. It is far better that you pray that God may water your mind lest virtue wither away in it. You are greatly concerned with money that is lost or being wasted, or you worry about the advance of old age. I think it much to be desired that you provide first of all for the needs of your soul.

What is exalted among men is an abomination in the sight of God.

A millennial belief in a Holy God may have the effect of deepening the soul, but it is also obviously archaic, and modern influences would presently bring me up to date and reveal how antiquated my origins were. To turn away from those origins, however, has always seemed to me an utter impossibility. It would be a treason to my first consciousness to un-Jew myself.

Correspondences are like small clothes before the invention of suspenders; it is impossible to keep them up.

Just as the wave cannot exist for itself, but is ever a part of the heaving surface of the ocean, so must I never live my life for itself, but always in the experience which is going on around me. It is an uncomfortable doctrine which the true ethics whisper into my ear. You are happy, they say; therefore you are called upon to give much.

But by far the greatest obstacle to the progress of science and to the undertaking of new tasks and provinces therein is found in this - that men despair and think things impossible.

This they do in the service of an imaginary science; and, like the astrologers and soothsayers whom they have succeeded, cast up their eyes to the clouds, and speak in immense, unsubstantiated images and similes, in deeply misleading metaphors and allegories, and make use of hypnotic formulae with little regard for experience, or rational argument, or tests of proven reliability. Thereby they throw dust in their own eyes as well as in ours, obstruct our vision of the real world, and further confuse an already sufficiently bewildered public about the relations of morality to politics, and about the nature and methods of the natural sciences and historical studies alike.

The concept of the state presupposes the concept of the political.

Man is condemned to be free; because once thrown into the world, he is responsible for everything he does.

All affected can accept the consequences and the side effects that [the norm's] general observance can be anticipated to have for the satisfaction of everyone's interests, and the consequences are preferred to those of known alternative possibilities for regulation.

It is precisely the essential feature of egoism that it does not apprehend the full value of the isolated self. The egoist sees himself only with regard to the others, as a member of society who wishes to possess and acquire more than the others. Self-directedness or other-directedness have no essential bearing on the specific quality of love or hatred. These acts are different in themselves, quite independently of their direction.

Of course I base my characters partly on the people I know-one can't escape it-but fictional characters are oversimplified; they're much less complex than the people one knows.

What must be remembered in any case is that secret complicity that joins the logical and the everyday to the tragic.

In Deductive Reasoning, we cannot have any truth in the conclusion which is not virtually contained in the premises.

History, if viewed as a repository for more than anecdote or chronology, could produce a decisive transformation in the image of science by which we are now possessed.

The truth is cruel, but it can be loved, and it makes free those who have loved it.

The whole life of the upper classes is a constant inconsistency. The more delicate a man's conscience is, the more painful this contradiction is to him.

Self-pity is not as sterile as we suppose. Once we feel its mere onset, we assume a thinker's attitude, and come to think of it, we come to think!

My theory is that all women have hydrofluoric acid bottled up inside.
