Life's short span forbids us to enter on far reaching hopes.

There are, indeed, things that cannot be put into words. They make themselves manifest. They are what is mystical.

The progressive world is necessarily divided into two classes - those who take the best of what there is and enjoy it - those who wish for something better and try to create it. Without these two classes the world would be badly off. They are the very conditions of progress, both the one and the other. Were there none who were discontented with what they have, the world would never reach anything better.

The consciousness of being betrayed is to the collective consciousness of a sacred group what a certain form of schizophrenia is to the individual...it is a form of madness.

Sometimes it is said that man can not be trusted with the government of himself. Can he, then, be trusted with the government of others? Or have we found angels in the forms of kings to govern him? Let history answer this question.

The aim of research is the discovery of the equations which subsist between the elements of phenomena.

In the torments of the intellect, there is a certain bearing which is to be sought in vain among those of the heart. Skepticism is the elegance of anxiety.

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.

No evil is honorable; but death is honorable; therefore death is not evil.

The argument of this book is that we, and all other animals, are machines created by our genes.

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.

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.

Now he saw the problem with great clarity. If he lived here, life would be pleasant and safe. But it would also be predictable. A child could be born here, grow up here, die here, without ever experiencing the excitement of discovery. Why did Dona question him endlessly about his life in the burrow and his journey to the country of the ants? Because for her, it represented a world that was dangerous and full of fascinating possibilities. For the children of this underground city, life was a matter of repetition, of habit. And this, he suddenly realized, was the heart of the problem. Habit. Habit was a stifling, warm blanket that threatened you with suffocation and lulled the mind into a state of perpetual nagging dissatisfaction. Habit meant the inability to escape from yourself, to change and develop . . .

I do not believe that civilizations have to die...Civilization is not an organism. It is a product of wills.

But if we discard this definition of a people, and, assuming another, say that a people is an assemblage of reasonable beings bound together by a common agreement as to the objects of their love, then, in order to discover the character of any people, we have only to observe what they love. Yet whatever it loves, if only it is an assemblage of reasonable beings and not of beasts, and is bound together by an agreement as to the objects of love, it is reasonably called a people; and it will be a superior people in proportion as it is bound together by higher interests, inferior in proportion as it is bound together by lower.

I wish to suggest that a man may be very industrious, and yet not spend his time well. There is no more fatal blunderer than he who consumes the greater part of his life getting his living. All great enterprises are self-supporting. The poet, for instance, must sustain his body by his poetry, as a steam planing-mill feeds its boilers with the shavings it makes. You must get your living by loving.

In my work, I have always tried to unite the true with the beautiful; but when I had to choose one or the other, I usually chose the beautiful. In a conversation with Freeman Dyson.

The man of principles has character. Of him we know definitely what to expect. He does not act on the basis of his instinct, but on the basis of his will. Therefore, without being redundant one can classify characteristics according to a person's faculty of desire (what is practical), as a) his nature, or natural talent, b) his temperament, or disposition, and c) his general character, or mode of thinking.

This I know, that between finite and infinite there is no comparison; so that the difference between God and the greatest and most excellent created thing is no less than the difference between God and the least created thing.

Though the managing ourselves well in this part of our behavior has the name good-breeding, as if a peculiar effect of education; yet... young children should not be much perplexed about it... Teach them humility, and to be good-natur'd, if you can, and this sort of manners will not be wanting; civility being in truth nothing but a care not to shew any slighting or contempt of any one in conversation.

My new trade of nail-making is to me in this country what an additional title of nobility or the ensigns of a new order are in Europe.

"The physical world is real." That is supposed to be the fundamental hypothesis. What does "hypothesis" mean here? For me, a hypothesis is a statement, whose truth must be assumed for the moment, but whose meaning must be raised above all ambiguity. The above statement appears to me, however, to be, in itself, meaningless, as if one said: "The physical world is cock-a-doodle-do." It appears to me that the "real" is an intrinsically empty, meaningless category (pigeon hole), whose monstrous importance lies only in the fact that I can do certain things in it and not certain others.

Crowley wanted to be a magician because he wanted power -- power over other people.

Even if a civil society were to be dissolved by the consent of all its members (e.g., if a people inhabiting an island decided to separate and disperse throughout the world), the last murderer remaining in prison would first have to be executed, so that each has done to him what his deeds deserve and blood guilt does not cling to the people for not having insisted upon this punishment; for otherwise the people can be regarded as collaborators in his public violation of justice.

(The end is) life in agreement with nature.

POLITICAL economy, considered as a branch of the science of a statesman or legislator, proposes two distinct objects: first, to provide a plentiful revenue or subsistence for the people, or more properly to enable them to provide such a revenue or subsistence for themselves; and secondly, to supply the state or commonwealth with a revenue sufficient for the public services. It proposes to enrich both the people and the sovereign.

After World War II, liberal rights were not something that were only deserved by white Europeans. ...There was a recognition that the black and brown peoples being held in colonial bondage could not consistently be held in that bondage, because liberalism was a universal doctrine. ...That's the other respect in which we can defend liberalism, a moral one.

All science must start with some assumptions as to the ultimate analysis of the facts with which it deals. These assumptions are justified partly by their adherence to the types of occurrence of which we are directly conscious, and partly by their success in representing the observed facts with a certain generality, devoid of ad hoc suppositions.

There can be no higher law in journalism than to tell the truth and shame the devil.

The aim of science is to seek the simplest explanations of complex facts. We are apt to fall into the error of thinking that the facts are simple because simplicity is the goal of our quest. The guiding motto in the life of every natural philosopher should be, "Seek simplicity and distrust it."

Industry controlled by society as a whole, and operated according to a plan, presupposes well-rounded human beings, their faculties developed in balanced fashion, able to see the system of production in its entirety.

The soldier is applauded who refuses to serve in an unjust war by those who do not refuse to sustain the unjust government which makes the war; is applauded by those whose own act and authority he disregards and sets at naught; as if the state were penitent to that degree that it hired one to scourge it while it sinned, but not to that degree that it left off sinning for a moment.

If the brutes have consciousness and no souls, then it is clear that, in them, consciousness is a direct function of material changes; while, if they possess immaterial subjects of consciousness, or souls, then, as consciousness is brought into existence only as the consequence of molecular motion of the brain, it follows that it is an indirect product of material changes. The soul stands related to the body as the bell of a clock to the works, and consciousness answers to the sound which the bell gives out when it is struck.

What remains is the remarkable and, for many, certainly disquieting diagnosis that all genuine political theories presuppose man to be evil, i.e., by no means an unproblematic but a dangerous and dynamic being.

Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a deep ocean of anguish, reaching to the very verge of despair.

A good prescription is still more profitable than an absolution.

When Bill Gates pours money into Africa for feeding the poor in Africa and preventing famine, he's pushing the failed Green Revolution, he's pushing chemicals, pushing GMOs, pushing patterns.

They are ill discoverers that think there is no land, when they can see nothing but sea.

I die adoring God, loving my friends, not hating my enemies, and detesting superstition.

A hero looks death in the face, real death, not just the image of death. Behaving honourably in a crisis doesn't mean being able to act the part of a hero well, as in the theatre, it means being able to look death itself in the eye. For an actor may play lots of different roles, but at the end of it all he himself, the human being, is the one who has to die.

The main characteristic of any event is that it has not been foreseen. We don't know the future but everybody acts into the future. Nobody knows what he is doing because the future is being done, action is being done by a "we" and not an "I." Only if I were the only one acting could I foretell the consequences of what I'm doing. What actually happens is entirely contingent, and contingency is indeed one of the biggest factors in all history.

Properly understood, then, the desire to act justly derives in part from the desire to express most fully what we are or can be, namely free and equal rational beings with the liberty to choose.

Today, empathetic intelligence entails sharing the sorrows of other sentient beings. In our posthuman future, will empathy consist entirely in sharing each other's joys?

When we are lulled into somnolence by lack of challenge every molehill tends to become a mountain, every minor inconvenience an intolerable imposition. For a self-chosen reality tends to become a prison. The factors that protect and insulate civilized man can easily end by suffocating him unless he possesses a high degree of self-discipline, the 'highly developed vital sense' that Shaw speaks of. And since clever and sensitive people are inclined to lack self-discipline, a high degree of culture usually involves a high degree of pessimism. This is what has happened to Western civilisation over the past two centuries. It explains why so many distinguished artists, writers and musicians have taken such a negative view of the human situation.

Freedom is the alone unoriginated birthright of man, and belongs to him by force of his humanity; and is independence on the will and co-action of every other in so far as this consists with every other person's freedom.
