Wherever big industries displaced manufacture, the bourgeoisie developed in wealth and power to the utmost and made itself the first class of the country. The result was that wherever this happened, the bourgeoisie took political power into its own hands and displaced the hitherto ruling classes, the aristocracy, the guildmasters, and their representative, the absolute monarchy. The bourgeoisie annihilated the power of the aristocracy, the nobility, by abolishing the entailment of estates - in other words, by making landed property subject to purchase and sale, and by doing away with the special privileges of the nobility. It destroyed the power of the guildmasters by abolishing guilds and handicraft privileges. In their place, it put competition - that is, a state of society in which everyone has the right to enter into any branch of industry, the only obstacle being a lack of the necessary capital.

In principle and in practice, in a right track and in a wrong one, the rarest of all human qualities is consistency.

The "passion for incredulity" can produce as much self-deception as the uncritical will to believe.

If in this book harsh words are spoken about some of the greatest among the intellectual leaders of mankind, my motive is not, I hope, the wish to belittle them. It springs rather from my conviction that, if our civilization is to survive, we must break with the habit of deference to great men. Great men may make great mistakes; and as the book tries to show, some of the greatest leaders of the past supported the perennial attack on freedom and reason. Their influence, too rarely challenged, continues to mislead those on whose defence civilization depends, and to divide them. The responsibility of this tragic and possibly fatal division becomes ours if we hesitate to be outspoken in our criticism of what admittedly is a part of our intellectual heritage. By reluctance to criticize some of it, we may help to destroy it all.

Some philosophers fail to distinguish propositions from judgments; ... But in the real world it is more important that a proposition be interesting than that it be true. The importance of truth is that it adds to interest.

A man must always live by his work, and his wages must at least be sufficient to maintain him. They must even upon most occasions be somewhat more, otherwise it would be impossible for him to bring up a family, and the race of such workmen could not last beyond the first generation.

But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.

Shame on the soul, to falter on the road of life while the body still perseveres.

Without an understanding of causality there can be no theory of communication. What passes as information theory today is not communication at all, but merely transportation.

The self-discipline of the Social Democracy is not merely the replacement of the authority of bourgeois rulers with the authority of a socialist central committee. The working class will acquire the sense of the new discipline, the freely assumed self-discipline of the Social Democracy, not as a result of the discipline imposed on it by the capitalist state, but by extirpating, to the last root, its old habits of obedience and servility.

I speak for the slave when I say that I prefer the philanthropy of Captain Brown to that philanthropy which neither shoots me nor liberates me.

The thirst after happiness is never extinguished in the heart of man.

Every difference of opinion is not a difference of principle. We have called by different names brethren of the same principle. We are all Republicans, we are all Federalists.

The world is the totality of facts, not things.

Man ought to be content, it is said; but with what?

Lysander, when Dionysius sent him two gowns, and bade him choose which he would carry to his daughter, said, "She can choose best," and so took both away with him.

Very little is needed to make a happy life.

The natural philosophy of Democritus and some others, who did not suppose a mind or reason in the frame of things, but attributed the form thereof able to maintain itself to infinite essays or proofs of nature, which they term fortune, seemeth to me... in particularities of physical causes more real and better inquired than that of Aristotle and Plato; whereof both intermingled final causes, the one as a part of theology, and the other as a part of logic, which were the favourite studies respectively of both those persons. Not because those final causes are not true, and worthy to be inquired, being kept within their own province; but because their excursions into the limits of physical causes hath bred a vastness and solitude in that tract.

Nothing makes one old so quickly as the ever-present thought that one is growing older.

The more you live, the less useful it seems to have lived.

After all, in the poets love has its priests, and sometimes one hears a voice which knows how to defend it; but of faith one hears never a word. Who speaks in honor of this passion? Philosophy goes further. Theology sits rouged at the window and courts its favor, offering to sell her charms to philosophy. it is supposed to be difficult to understand Hegel, but to understand Abraham is a trifle. To go beyond Hegel's is a miracle, but to get beyond Abraham is the easiest thing of all.

The progress of human knowledge depends on maintaining that touch of scepticism even about the most "unquestionable" truths. A century ago, Darwin's theory of evolution by natural selection was regarded as scientifically unshakeable; today, most biologists have their reservations about it. Fifty years ago, Freud's sexual theory of neurosis was accepted by most psychiatrists; today, it is widely recognized that his methods were highly questionable. At the turn of this century, a scientist who questioned Newton's theory of gravity would have been regarded as insane; twenty years later, it had been supplanted by Einstein's theory, although, significantly, few people actually understood it. It seems perfectly conceivable that our descendants of the twenty-second century will wonder how any of us could have been stupid enough to have been taken in by Darwin, Freud or Einstein.

The goal of liberalism is the peaceful cooperation of all men. It aims at peace among nations too. When there is private ownership of the means of production everywhere and when laws, the tribunals and the administration treat foreigners and citizens on equal terms, it is of little importance where a country's frontiers are drawn. Nobody can derive any profit from conquest, but many can suffer losses from fighting. War no longer pays; there is no motive for aggression. The population of every territory is free to determine to which state it wishes to belong, or whether it prefers to establish a state of its own. All nations can coexist peacefully, because no nation is concerned about the size of its state.

Peace to the shacks! War on the palaces!

Writing is like getting married. One should never commit oneself until one is amazed at one's luck.

Life creates itself in delirium and is undone in ennui.

His business is here, it is here that he is despised and vilified, it is here that he must carry out his undertaking.

That men do not learn very much from the lessons of history is the most important of all the lessons that history has to teach.

We may say with truth and meaning that governments are more or less republican, as they have more or less of the element of popular election and control in their composition; and believing, as I do, that the mass of the citizens is the safest depository of their own rights, and especially, that the evils flowing from the duperies of the people are less injurious than those from the egoism of their agents, I am a friend to that composition of government which has in it the most of this ingredient. And I sincerely believe, with you, that banking establishments are more dangerous than standing armies; and that the principle of spending money to be paid by posterity, under the name of funding, is but swindling futurity on a large scale.

"Education to personality" has become a pedagogical ideal that turns its back upon the standardized-the collective and normal-human being. It thus fittingly recognizes the historical fact that the great, liberating deeds of world history have come from leading personalities and never from the inert mass that is secondary at all times and needs a demagogue if it is to move at all. The paean of the Italian nation is addressed to the personality of the Duce, and dirges of other nations lament the absence of great leaders.

Thus mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.

Marxism is a revolutionary worldview that must always struggle for new revelations. Marxism must abhor nothing so much as the possibility that it becomes congealed in its current form. It is at its best when butting heads in self-criticism, and in historical thunder and lightning, it retains its strength.

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...

Hayek watched the interwar collapse with horror, as Keynes did, and shared many of Keynes's liberal values. What he failed to understand is that these values cannot be renewed by applying any formula or doctrine, or by trying to construct an ideal liberal regime in which freedom is insulated from the contingencies of politics.

Human beings act, certainly. But none of them knows why they act as they do. There is a scattering of facts, which can be known and reported. Beyond these facts are the stories that are told. Human beings may behave like puppets, but no one is pulling the strings.

The following general definition of an animal: a system of different organic molecules that have combined with one another, under the impulsion of a sensation similar to an obtuse and muffled sense of touch given to them by the creator of matter as a whole, until each one of them has found the most suitable position for it shape and comfort.

The sense of justice and injustice is not deriv'd from nature, but arises artificially... from education, and human conventions.

I am endeavouring in a general way to explain the laws of double refraction on this hypothesis, but have not yet arrived at any results sufficiently decisive to be communicated.

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 military mind remains unparalleled as a vehicle of creative stupidity.

"This is the truth," we say. "You can discuss it as much as you want; we aren't interested. But in a few years there'll be the police who will show you we are right."

Grief and disappointment give rise to anger, anger to envy, envy to malice, and malice to grief again, till the whole circle be completed.

The idea of Christ is much older than Christianity.

Pornography and obscenity...work by specialism and fragmentation. They deal with a figure without a ground -- situations in which the human factor is suppressed in favor of sensations and kicks.

If we want eternal life, then we'll need to rewrite our bug-ridden genetic code and become god-like. "May all that have life be delivered from suffering", said Gautama Buddha. It's a wonderful sentiment. Sadly, only hi-tech solutions can ever eradicate suffering from the living world. Compassion alone is not enough.

But if Germany, thanks to Hitler and his successors, were to enslave the European nations and destroy most of the treasures of their past, future historians would certainly pronounce that she had civilized Europe.

Hear the verbal protestations of all men: Nothing so certain as their religious tenets. Examine their lives: You will scarcely think that they repose the smallest confidence in them. The greatest and truest zeal gives us no security against hypocrisy: The most open impiety is attended with a secret dread and compunction. No theological absurdities so glaring that they have not, sometimes, been embraced by men of the greatest and most cultivated understanding. No religious precepts so rigorous that they have not been adopted by the most voluptuous and most abandoned of men.
