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.

What was observed by us in the third place is the nature or matter of the Milky Way itself, which, with the aid of the spyglass, may be observed so well that all the disputes that for so many generations have vexed philosophers are destroyed by visible certainty, and we are liberated from wordy arguments.

There is only this swarm of dying creatures stricken with longevity, all the more hateful in that they are so good at organizing their agony. p. 120, first American edition

Men think it right to eat animals, because they are led to believe that God sanctions it. This is untrue. No matter in what books it may be written that it is not sinful to slay animals and to eat them, it is more clearly written in the heart of man than in any books that animals are to be pitied and should not be slain any more than human beings. We all know this if we do not choke the voice of our conscience.

Woe to the book you can read without constantly wondering about the author!

Here is a fulfillment of long centuries of civilization and culture; here, in romantic love, more than the triumph of thought or the victories of power is the topmost reach of human beings.

Friends are not primarily absorbed in each other. It is when we are doing things together that friendship springs up - painting, sailing ships, praying, philosophizing, fighting shoulder to shoulder. Friends look in the same direction. Lovers look at each other - that is, in opposite directions. To transfer bodily all that belongs to one relationship into the other is blundering.

It is love that leniently and mercifully says: I forgive you everything-if you are forgiven only little, then it is because you love only little. Justice severely sets the boundary and says: No further! This is the limit. For you there is no forgiveness, and there is nothing more to be said.

Freedom only for the supporters of the government, only for the members of one party - however numerous they may be - is no freedom at all. Freedom is always and exclusively freedom for the one who thinks differently. Not because of any fanatical concept of "justice" but because all that is instructive, wholesome and purifying in political freedom depends on this essential characteristic, and its effectiveness vanishes when "freedom" becomes a special privilege.

Today we have arrived at a point when the three principles [of modern resistance: 1. measure of efficacy, 2. the form of political and military organization correspond to the current forms of economic and social production, 3. democracy and freedom] coincide. The distributed network structure provides the model for an absolutely democratic organization that corresponds to the dominant forms of economic and social production and is also the most powerful weapon against the ruling power structure.

We have unmistakable proof that throughout all past time, there has been a ceaseless devouring of the weak by the strong.

It is the duty of the human understanding to understand that there are things which it cannot understand, and what those things are. Human understanding has vulgarly occupied itself with nothing but understanding, but if it would only take the trouble to understand itself at the same time it would simply have to posit the paradox.

Jesus Christ raised women above the condition of mere slaves, mere ministers to the passions of the man, raised them by His sympathy, to be Ministers of God. He gave them moral activity. But the Age, the World, Humanity, must give them the means to exercise this moral activity, must give them intellectual cultivation, spheres of action.

It is indeed foolish to be unhappy now because you may be unhappy at some future time.

Cato said the best way to keep good acts in memory was to refresh them with new.

Ethics occupies a central place in philosophy because it is concerned with sin, with the origin of good and evil and with moral valuations. And since these problems have a universal significance, the sphere of ethics is wider than is generally supposed. It deals with meaning and value and its province is the world in which the distinction between good and evil is drawn, evaluations are made and meaning is sought.

To be taken without consent from my home and friends; to lose my liberty; to undergo all those assaults on my personality which modern psychotherapy knows how to deliver; to be re-made after some pattern of "normality" hatched in a Viennese laboratory to which I never professed allegiance; to know that this process will never end until either my captors have succeeded or I have grown wise enough to cheat them with apparent success-who cares whether this is called Punishment or not? "The Humanitarian Theory of Punishment"

The judge is condemned when the guilty is absolved.

The great secret of success is to go through life as a man who never gets used up. That is possible for him who never argues and strives with men and facts, but in all experience retires upon himself, and looks for the ultimate cause of things in himself.

A mother gave her children Aesop's fables to read, in the hope of educating and improving their minds; but they very soon brought the book back, and the eldest, wise beyond his years, delivered himself as follows: This is no book for us; it's much too childish and stupid. You can't make us believe that foxes and wolves and ravens are able to talk; we've got beyond stories of that kind! In these young hopefuls you have the enlightened Rationalists of the future.

The unfortunate thing about public misfortunes is that everyone regards himself as qualified to talk about them.

Every step of real movement is more important than a dozen programmes.

Neither a man nor a crowd nor a nation can be trusted to act humanely or to think sanely under the influence of a great fear.

One cannot collect all the beautiful shells on the beach. One can collect only a few, and they are more beautiful if they are few.

I believe that man is the product of natural evolution that is born from the conflict of being a prisoner and separated from nature, and from the need to find unity and harmony with it.

By virtue of the way it has organized its technological base, contemporary industrial society tends to be totalitarian. For "totalitarian" is not only a terroristic political coordination of society, but also a non-terroristic economic-technical coordination which operates through the manipulation of needs by vested interests.

Proletarian violence, carried on as a pure and simple manifestation of the sentiment of class struggle, appears thus as a very fine and heroic thing; it is at the service of the immemorial interests of civilization; it is not perhaps the most appropriate method of obtaining immediate material advantages, but it may save the world from barbarism.

To do the opposite of something is also a form of imitation, namely an imitation of its opposite.

For it is not death or pain that is to be feared, but the fear of pain or death.

What maintains the marriage and what is it? Only the knowledge of the hearts, that is its beginning and end.

It is a base thing for the countenance to be obedient and to regulate and compose itself as the mind commands, and for the mind not to be regulated and composed by itself.

There is no objective reality. But there is only an illusion of consciousness, there is only an objectivication of reality, which was created by the spirit. The origin of life is creativity, freedom; and the personality, subject, and spirit are the representatives of that origin, but not the nature, not the object.

Once introduced discontinuity, once challenge any of the properties of visual space, and as they flow from each other, the whole conceptual framework collapses.

The principal aim of mathematical education is to develop certain faculties of the mind, and among these intuition is not the least precious. It is through it that the mathematical world remains in touch with the real world, and even if pure mathematics could do without it, we should still have to have recourse to it to fill up the gulf that separates the symbol from reality.

In my opinion, all things in nature occur mathematically.

Our laws, language, religion, politics, & manners are so deeply laid in English foundations, that we shall never cease to consider their history as a part of ours, and to study ours in that as it's origin.

What should we gain by a definition, as it can only lead us to other undefined terms?

Existence precedes and rules essence.

Can the children of the bridechamber mourn, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and then shall they fast. No man putteth a piece of new cloth unto an old garment, for that which is put in to fill it up taketh from the garment, and the rent is made worse. Neither do men put new wine into old bottles: else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved.

If any philosopher had been asked for a definition of infinity, he might have produced some unintelligible rigmarole, but he would certainly not have been able to give a definition that had any meaning at all.

Nay, am not I also the humble James Carlyle's work? I owe him much more than existence, I owe him a noble inspiring example (now that I can read it in that rustic character). It was he exclusively that determined on educating me; that from his small hard-earned funds sent me to school and college, and made me whatever I am or may become. Let me not mourn for my father, let me do worthily of him. So shall he still live even here in me, and his worth plant itself honorably forth into new generations.

An art that heals and protects its subject is a geography of scars.

There is no sin, and there can be no sin on all the earth, which the Lord will not forgive to the truly repentant! Man cannot commit a sin so great as to exhaust the infinite love of God. Can there be a sin which could exceed the love of God?

The real is not only what can be reproduced, but that which is already reproduced, the hyper-real.

By a lie a man throws away and, as it were, annihilates his dignity as a man. A man who himself does not believe what he tells another ... has even less worth than if he were a mere thing. ... makes himself a mere deceptive appearance of man, not man himself.
