Hayek's theory of evolutionary rationality shows how traditions and customs (those surrounding sexual relations, for example) might be reasonable solutions to complex social problems, even when, and especially when, no clear rational grounds can be provided to the individual for obeying them. These customs have been selected by the ''invisible hand'' of social reproduction, and societies that reject them will soon enter the condition of ''maladaptation,'' which is the normal prelude to extinction.

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

Speech and silence. We feel safer with a madman who talks than with one who cannot open his mouth.

The theory of Communism may be summed up in the single sentence: Abolition of private property.

The welfare of the people in particular has always been the alibi of tyrants, and it provides the further advantage of giving the servants of tyranny a good conscience. It would be easy, however, to destroy that good conscience by shouting to them: if you want the happiness of the people, let them speak out and tell what kind of happiness they want and what kind they don't want! But, in truth, the very ones who make use of such alibis know they are lies; they leave to their intellectuals on duty the chore of believing in them and of proving that religion, patriotism, and justice need for their survival the sacrifice of freedom.

As usurpation is the exercise of power which another has a right to, so tyranny is the exercise of power beyond right, which nobody can have a right to...

Take provocation, for instance, which is the opposite and the caricature of seduction. It says: "I know that you want to be seduced, and I will seduce you." Nothing could be worse than betraying this secret rule. Nothing could be less seductive than a provocative smile or inciteful behaviour, since both presuppose that one cannot be seduced naturally and that one needs to be blackmailed into it, or through a declaration of intent: "Let me seduce you"

Verily I say unto you, I have not found so great faith, no, not in Israel. And I say unto you, That many shall come from the east and west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven. But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth.

To all Christian governments Christianity was not a rule of means but a means of rule; Christ was for the people, Machiavelli was preferred by the kings. The state in some measure had civilized man, but who would civilize the state?

I would advise no one to send his child where the Holy Scriptures are not supreme. Every institution that does not unceasingly pursue the study of God's word becomes corrupt. Because of this we can see what kind of people they become in the universities and what they are like now. Nobody is to blame for this except the pope, the bishops, and the prelates, who are all charged with training young people. The universities only ought to turn out men who are experts in the Holy Scriptures, men who can become bishops and priests, and stand in the front line against heretics, the devil, and all the world. But where do you find that? I greatly fear that the universities, unless they teach the Holy Scriptures diligently and impress them on the young students, are wide gates to hell.

Big industry, freed from the pressure of private property, will undergo such an expansion that what we now see will seem as petty in comparison as manufacture seems when put beside the big industry of our own day. This development of industry will make available to society a sufficient mass of products to satisfy the needs of everyone. The same will be true of agriculture, which also suffers from the pressure of private property and is held back by the division of privately owned land into small parcels. Here, existing improvements and scientific procedures will be put into practice, with a resulting leap forward which will assure to society all the products it needs. In this way, such an abundance of goods will be able to satisfy the needs of all its members.

While moral rules may be propounded by authority the fact that these were so propounded would not validate them.

Fundamentally we are highly social creatures. We feel a big sense of anomie and discomfort when we are isolated from our fellow human beings. …We seek community in different ways. There's a right wing... and... a left wing version of this.

The history of other cultures is non-existent until it erupts in confrontation with the United States.

Sometimes a scream is better than a thesis.

One has to do something new in order to see something new.

The core of common culture is religion. Tribes survive and flourish because they have gods, who fuse many wills into a single will, and demand and reward the sacrifices on which social life depends.

The State's behavior is violence, and it calls its violence "law"; that of the individual, "crime." The state calls its own violence law, but that of the individual, crime.

One might say: art shows us the miracles of nature. It is based on the concept of the miracles of nature.

There is the name and the thing: the name is a voice which denotes and signifies the thing; the name is no part of the thing, nor of the substance; 'tis a foreign piece joined to the thing, and outside it. God, who is all fulness in Himself and the height of all perfection, cannot augment or add anything to Himself within; but His name may be augmented and increased by the blessing and praise we attribute to His exterior works: which praise, seeing we cannot incorporate it in Him, forasmuch as He can have no accession of good, we attribute to His name, which is the part out of Him that is nearest to us. Thus is it that to God alone glory and honour appertain; and there is nothing so remote from reason as that we should go in quest of it for ourselves; for, being indigent and necessitous within, our essence being imperfect, and having continual need of amelioration, 'tis to that we ought to employ all our endeavour.

Every one knows that there are no real forests in England. The deer in the parks of the great are demurely domestic cattle, fat as London alderman.

Make thyself pure, 0 righteous man! Anyone in the world here below can win purity for himself, namely, when he cleanses himself with Good Thoughts, Good Words, and Good Deeds.

It is, therefore, a just political maxim, that every man must be supposed a knave: Though at the same time, it appears somewhat strange, that a maxim should be true in politics, which is false in fact. But to satisfy us on this head, we may consider, that men are generally more honest in their private than in their public capacity, and will go greater lengths to serve a party, than when their own private interest is alone concerned. Honour is a great check upon mankind: But where a considerable body of men act together, this check is, in a great measure, removed; since a man is sure to be approved of by his own party, for what promotes the common interest; and he soon learns to despise the clamours of adversaries.

There is no belief, however foolish, that will not gather its faithful adherents who will defend it to the death.

I am looking forward very much to getting back to Cambridge, and being able to say what I think and not to mean what I say: two things which at home are impossible. Cambridge is one of the few places where one can talk unlimited nonsense and generalities without anyone pulling one up or confronting one with them when one says just the opposite the next day.

For the kingdom of heaven is with us today.

I remember the very place in Hyde Park where, in my fourteenth year, on the eve of leaving my father's house for a long absence, he told me that I should find, as I got acquainted with new people, that I had been taught many things which youths of my age did not commonly know; and that many persons would be disposed to talk to me of this, and to compliment me upon it. What other things he said on this topic I remember very imperfectly; but he wound up by saying, that whatever I knew more than others, could not be ascribed to any merit in me, but to the very unusual advantage which had fallen to my lot.

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.

"What is truth?" is a fundamental question. But what is it compared to "How to endure life?" And even this one pales beside the next: "How to endure oneself?" - That is the crucial question in which no one is in a position to give us an answer.

In Nietzsche's view nihilism is not a Weltanschauung that occurs at some time and place or another; it is rather the basic character of what happens in Occidental history.

Whoever heard me assert that the grey cat playing just now in the yard is the same one that did jumps and tricks there five hundred years ago will think whatever he likes of me, but it is a stranger form of madness to imagine that the present-day cat is fundamentally an entirely different one.

The artist in realizing his own individuality reveals potentialities hitherto unrealized. The revelation is the inspiration of other individuals to make the potentialities real, for it is not sheer revolt against things as they are which stirs human endeavor to its depth, but vision of what might be and is not. Subordination of the artists to any special cause no matter how worthy does violence not only to the artist but to the living source of a new and better future.

Children and fools speak the truth; and somehow they find happiness in their sincerity.

The most elementary form of rebellion, paradoxically, expresses an aspiration for order.

While Poe and the Symbolists were exploring the irrational in literature, Freud had begun to explore the resonant figure/ground double-plot of the conscious and unconscious.

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?

If two men who were friends in their youth meet again when they are old, after being separated for a life-time, the chief feeling they will have at the sight of each other will be one of complete disappointment at life as a whole; because their thoughts will be carried back to that earlier time when life seemed so fair as it lay spread out before them in the rosy light of dawn, promised so much - and then performed so little.

A created thing is never invented and it is never true: it is always and ever itself.

Truth will sooner come out from error than from confusion.

Go further, and require each of them to make a contribution: you will see how many things are still missing, and you will be obliged to get the assistance of a large number of men who belong to different classes, priceless men, but to whom the gates of the academies are nonetheless closed because of their social station. All the members of these learned societies are more than is needed for a single object of human science; all the societies together are not sufficient for a science of man in general.

From Plato's Republic... the primary danger of liberty and free speech in a democracy is what results when everyone has his own... style of life... For then there can be no common logos, no possible unity, for the city.

The power of the people and the power of reason are one.

Gutenberg made all history available as classified data: the transportable book brought the world of the dead into the space of the gentlemen's library; the telegraph brought the entire world of the living to the workman's breakfast table.

Perhaps the promise of phallus is always dissatisfying in some way.

The human soul has need of consented obedience and of liberty. Consented obedience is what one concedes to an authority because one judges it to be legitimate. It is not possible in relation to a political power established by conquest or coup d'etat nor to an economic power based upon money. Liberty is the power of choice within the latitude left between the direct constraint of natural forces and the authority accepted as legitimate. The latitude should be sufficiently wide for liberty to be more than a fiction, but it should include only what is innocent and should never be wide enough to permit certain kinds of crime.

Envy, jealousy, ambition, any kind of greed are passions; love is an action, the practice of human power, which can be practiced only in freedom and never as a result of compulsion. Love is an activity, not a passive affect; it is a "standing in," not a "falling for." In the most general way, the active character of love can be described by stating that love is primarily giving, not receiving.
