It is terrible to see how a single unclear idea, a single formula without meaning, lurking in a young man's head, will sometimes act like an obstruction ... in an artery, hindering the nutrition of the brain, and condemning its victim to pine away in the fullness of his intellectual vigor and in the midst of intellectual plenty.

Bitter for a free man is the bondage of debt.

What a hell of an economic system! Some are replete with everything while others, whose stomachs are no less demanding, whose hunger is just as recurrent, have nothing to bite on. The worst of it is the constrained posture need puts you in. The needy man does not walk like the rest; he skips, slithers, twists, crawls.

By an object, I mean anything that we can think, i.e. anything we can talk about.

It would be a piece of ingenuousness to accuse the man of to-day of his lack of moral code. The accusation would leave him cold, or rather, would flatter him. Immoralism has become a commonplace, and anybody and everybody boasts of practising it.

The public health authorities never mention the main reason many Americans have for smoking heavily, which is that smoking is a fairly sure, fairly honorable form of suicide.

Crime is naught but misdirected energy. So long as every institution of today, economic, political, social, and moral, conspires to misdirect human energy into wrong channels; so long as most people are out of place doing the things they hate to do, living a life they loathe to live, crime will be inevitable, and all the laws on the statutes can only increase, but never do away with, crime.

In the days before machinery men and women who wanted to amuse themselves were compelled, in their humble way, to be artists. Now they sit still and permit professionals to entertain them by the aid of machinery. It is difficult to believe that general artistic culture can flourish in this atmosphere of passivity.

The republican is the only form of government which is not eternally at open or secret war with the rights of mankind.

It is requisite to choose the most excellent life; for custom will make it pleasant. Wealth is an infirm anchor, glory is still more infirm; and in a similar manner, the body, dominion, and honour. For all these are imbecile and powerless. What then are powerful anchors. Prudence, magnanimity, fortitude. These no tempest can shake. This is the Law of God, that virtue is the only thing that is strong; and that every thing else is a trifle.

A bad feeling is a commotion of the mind repugnant to reason, and against nature.

There is no passion so contagious as that of fear.

The constitution of madness as mental illness, at the end of the eighteenth century, bears witness to a rupture in a dialogue, gives the separation as already enacted, and expels from the memory all those imperfect words, of no fixed syntax, spoken falteringly, in which the exchange between madness and reason was carried out. The language of psychiatry, which is a monologue by reason about madness, could only have come into existence in such a silence.

History, it is easily perceived, is a picture-gallery containing a host of copies and very few originals.

Who are those people by whom you wish to be admired? Are they not these about whom you are in the habit of saying that they are mad? What then? Do you wish to be admired by the mad?

"If God did not exist, he would have to be invented." But all nature cries aloud that he does exist: that there is a supreme intelligence, an immense power, an admirable order, and everything teaches us our own dependence on it.

If children were brought into the world by an act of pure reason alone, would the human race continue to exist? Would not a man rather have so much sympathy with the coming generation as to spare it the burden of existence?

Each visitor performed the ceremony of greeting this old aunt whom not one of them knew, not one of them wanted to know, and not one of them cared about; Anna Pávlovna observed these greetings with mournful and solemn interest and silent approval. The aunt spoke to each of them in the same words, about their health and her own, and the health of Her Majesty, "who, thank God, was better today." And each visitor, though politeness prevented his showing impatience, left the old woman with a sense of relief at having performed a vexatious duty and did not return to her the whole evening.

That which Fortune has not given, she cannot take away.

It is true that if philosophers have suffered their cause has been amply avenged. Extinguished theologians lie about the cradle of every science as the strangled snakes beside that of Hercules; and history records that whenever science and orthodoxy have been fairly opposed, the latter has been forced to retire from the lists, bleeding and crushed if not annihilated; scotched, if not slain. But orthodoxy is the Bourbon of the world of thought. It learns not, neither can it forget; and though, at present, bewildered and afraid to move, it is as willing as ever to insist that the first chapter of Genesis contains the beginning and the end of sound science... Darwiniana: the Origin of Species

Violence is the effort to maintain and restore a weakened psyche.

In Administrative Behavior, bounded rationality is largely characterized as a residual category - rationality is bounded when it falls short of omniscience. And the failures of omniscience are largely failures of knowing all the alternatives, uncertainty about relevant exogenous events, and inability to calculate consequences. There was needed a more positive and formal characterization of the mechanisms of choice under conditions of bounded rationality... Two concepts are central to the characterization: search and satisficing.

There is the world for you. Beauty, true beauty, is intangible. It is in the eye of the beholder. Something that we can lose at any moment, and the more you examine it, the more illusive it becomes. True happiness is virtue, and virtue is predicated on knowledge and righteous conduct.

The rise of new science in the seventeenth century laid hold upon general culture in the next century. The enlightenment... testified to the widespread belief that at last light had dawned, that dissipation of ignorance, superstition, and bigotry was at hand, and the triumph of reason was assured -- for reason was counterpart in man of the laws of nature which science was disclosing. The reign of law in the natural world was to be followed by the reign of law in human affairs.

If it is the moral right we are to look at, I say, that on every principle of moral obligation, I hold that the Jew has a right to political power.

For we carry our fate with us - and it carries us.

If terms are systematically good, they are not to be rejected because they are etymologically inaccurate.

Blest is that nation whose silent course of happiness furnishes nothing for history to say.

When you live alone you no longer know what it is to tell a story: the plausible disappears at the same time as the friends. You let events flow by too: you suddenly see people appear who speak and then go away; you plunge into stories of which you can't make head or tail: you'd make a terrible witness.

I heard what you were saying. You - you know nothing of my work. You mean my whole fallacy is wrong. How you ever got to teach a course in anything is totally amazing.

I am not afraid to appeal to the nation at large, to posterity, and still less to that Being Who sees Himself our motives, Who will judge us from His own knowledge of them.

Catherine: Why commit Evil? Goetz: Because Good has already been done. Catherine: Who has done it? Goetz: God the Father. I, on the other hand, am improvising.

Persons who feel themselves to be exiles in this world-and what noble mind, from Empedocles down, has not had that feeling?-are mightily inclined to believe themselves citizens of another.

Liberalism has merely cleared a field in which every soul and every corporate interest may fight with every other for domination. Whoever is victorious in this struggle will make an end of liberalism; and the new order, which will deem itself saved, will have to defend itself in the following age against a new crop of rebels.

To live, by definition, is not something one learns. Not from oneself, it is not learned from life, taught by life. Only from the other and by death. In any case from the other at the edge of life. At the internal border or the external border, it is a heterodidactics between life and death.

Physics is to be regarded not so much as the study of something a priori given, but rather as the development of methods of ordering and surveying human experience. In this respect our task must be to account for such experience in a manner independent of individual subjective judgement and therefore objective in the sense that it can be unambiguously communicated in ordinary human language.

A geometrician has learned to perform the most difficult demonstrations and calculations, as a monkey has learned to take his little hat off and on...

The guidelines for achieving wisdom consist of three leading maxims: 1) Think for yourself; 2) (in communication with other people) Put yourself in the place of the other person; 3) Always think by remaining faithful to your own self.

For anyone who at the end of Western philosophy can and must still question philosophically, the decisive question is no longer merely "What basic character do beings manifest?" or "How may the being of beings be characterized?" but "What is this 'being' itself?" The decisive question is that of "the meaning of being," not merely that of the being of beings.

By now it may be clear that the position I'm developing is a sort of post-Darwinian Kantianism.

The mind is the ruler of the soul. It should remain unstirred by agitations of the flesh--gentle and violent ones alike. Not mingling with them, but fencing itself off and keeping those feelings in their place. When they make their way into our thoughts, through the sympathetic link between mind and body, don't try to resist the sensation. The sensation is natural. But don't let the mind start in with judgments, calling it 'good' or 'bad.'

Those who will not worship at the shrine of money, need not hope for recognition. On the other hand, they will also not have to think other people's thoughts or wear other people's political clothes. They will not have to proclaim as true that which is false, nor praise that as humanitarian which is brutal.

Wisdom: The first error is that of the southern people, and it consists in holding that these eastern and western places are real places. ... give no quarter to that thought, whether it threatens you with fear, or tempts you with hopes. For this is Superstition and all who believe it will come in the end to the swamps to the south and the jungles to the far south.

For anyone who is alone, without God and without a master, the weight of days is dreadful. Hence one must choose a master, God being out of style.

God made us: invented us as a man invents an engine. A car is made to run on petrol, and it would not run properly on anything else. Now God designed the human machine to run on Himself.

Subject matters in general do not exist. There are no subject matters; no branches of learning-or, rather, of inquiry: there are only problems, and the urge to solve them.

The living force of his soul gained the day: on he passed far beyond the flaming walls of the world and traversed throughout in mind and spirit the immeasurable universe.
