Respectable scientists like de Broglie himself accept wave mechanics because it confers coherence and unity upon the experimental findings of contemporary science, and in spite of the astonishing changes it implies in connection with ideas of causality, time, and space, but it is because of these changes that it wins favor with the public. The great popular success of Einstein was the same thing. The public drinks in and swallows eagerly everything that tends to dispossess the intelligence in favor of some technique; it can hardly wait to abdicate from intelligence and reason and from everything that makes man responsible for his destiny.

The best university that can be recommended to a man of ideas is the gauntlet of the mobs.

There is no logical impossibility in the hypothesis that the world sprang into being five minutes ago, exactly as it then was, with a population that "remembered" a wholly unreal past. There is no logically necessary connection between events at different times; therefore nothing that is happening now or will happen in the future can disprove the hypothesis that the world began five minutes ago.

As one of our Swiss friends put it: "Now every German tailor living in Japan, China, or Moscow feels that he has the German navy and all of Germany's power behind him. This proud consciousness sends him into an insane rapture: the German has finally lived to see the day when he can say with pride, relying on his own state, like an Englishman or an American, 'I am a German.' True, when the Englishman or American says 'I am an Englishman,' or 'I am an American,' he is saying 'I am a free man.' The German, however, is saying 'I am a slave, but my emperor is stronger than all other princes, and the German soldier who is strangling me will strangle all of you.'"

Everyone who is seriously involved in the pursuit of science becomes convinced that some spirit is manifest in the laws of the universe, one that is vastly superior to that of man.

Death poses a problem which replaces all the others. What is deadly to philosophy, to the naive belief in the hierarchy of perplexities.

Considering the optimistic turn taken by world trade AT THIS MOMENT...it is some consolation at least that the revolution has begun in Russia, for I regard the convocation of 'notables' to Petersburg as such a beginning. ... On the Continent revolution is imminent and will, moreover, instantly assume a socialist character.

One gloomy and pessimistic writer with a powerful style affects a whole generation of writers, who in turn affect almost every educated person in the country.

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

Allow me, excellent Lucilius, to utter a still bolder word: if any goods could be greater than others, I should prefer those which seem harsh to those which are mild and alluring, and should pronounce them greater. For it is more of an accomplishment to break one's way through difficulties than to keep joy within bounds.

I did not direct my life. I didn't design it. I never made decisions. Things always came up and made them for me. That's what life is.

If we are uncritical we shall always find what we want: we shall look for, and find, confirmations, and we shall look away from, and not see, whatever might be dangerous to our pet theories. In this way it is only too easy to obtain what appears to be overwhelming evidence in favor of a theory which, if approached critically, would have been refuted.

Righteousness cannot be born until self-righteousness is dead.

The truth is a trap: you can not get it without it getting you; you cannot get the truth by capturing it, only by its capturing you.

We used to pay too little attention to utopias, or even disregard them altogether, saying with regret they were impossible of realisation. Now indeed they seem to be able to be brought about far more easily than we supposed, and we are actually faced by an agonising problem of quite another kind: how can we prevent their final realisation? ... Utopias are more realisable than those 'realist politics' that are only the carefully calculated policies of office-holders, and towards utopias we are moving. But it is possible that a new age is already beginning, in which cultured and intelligent people will dream of ways to avoid ideal states and to get back to a society that is less 'perfect' and more free.

'Intuitive' is opposed to 'discursive' reason. In intuition, we obtain our conclusions by dwelling upon 'one' aspect of the fundamental Idea; in discursive reasoning, we combine several aspects of the Idea

The Outsider wants to cease to be an Outsider. He wants to be 'balanced'. He would like to achieve a vividness of sense-perception (Lawrence, Van Gogh, Hemingway) He would also like to understand the human soul and its working and, be 'possessed' by a Will topower, to more life. (Barbusse and Mitya Karamazov) He would like to escape triviality forever. Above all, he would like to know how to express himself because that is the means by which he can get to know himself and hi unknown possibilities.

Eros and depression are opposites.

In order to cease being a doubtful case, one has to cease being, that's all.

Some people steal from others, or defraud them, or enslave them, seizing their product and preventing them from living as they choose, or forcibly exclude others from competing in exchanges. None of these are permissible modes of transition from one situation to another.

To suffer is to produce knowledge.

Know all ye mortals who have entered this contest, that according to our laws and decrees the victor is allowed to exult but the vanquished must not complain. Depart then wherever you please, and in future live every one of you under the guidance of the gods. Let every man choose his own guardian and guide.

The notion that one can discover large patterns or regularities in the procession of historical events is naturally attractive to those who are impressed by the success of the natural sciences in classifying, correlating, and above all predicting.

Every book is a quotation; and every house is a quotation out of all forests and mines and stone-quarries; and every man is a quotation from all his ancestors.

The highest and ultimate personality values are declared to be independent of contrasts like rich and poor, healthy and sick, etc. The world had become accustomed to considering the social hierarchy, based on status, wealth, vital strength, and power, as an exact image of the ultimate values of morality and personality. The only way to disclose the discovery of anew and higher sphere of being and life, of the "kingdom of God" whose order is independent of that worldly and vital hierarchy, was to stress the vanity of the old values in this higher order.

I shall doubtless outlive some troublesome desires; but I am in no hurry about that; nor, when the time comes, shall I plume myself on the immunity just in the same way, I do not greatly pride myself on having outlived my belief in the fairy tales of Socialism. Old people have faults of their own; they tend to become cowardly, niggardly, and suspicious. Whether from the growth of experience or the decline of animal heat, I see that age leads to these and certain other faults; and it follows, of course, that while in one sense I hope I am journeying towards the truth, in another I am indubitably posting towards these forms and sources of error.

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.

I like well your idea of issuing treasury notes bearing interest, because I am persuaded they would soon be withdrawn from circulation and locked up in vaults & private hoards. It would put it in the power of every man to lend his 100. or 1000 d. tho' not able to go forward on the great scale, and be the most advantageous way of obtaining a loan. The other idea of creating a National bank, I do not concur in, because it seems now decided that Congress has not that power, (altho' I sincerely wish they had it exclusively) and because I think there is already a vast redundancy, rather than a scarcity of paper medium.

History is a bath of blood.

All is ephemeral - fame and the famous as well.

All sources of energy upon which industry depends are wasted when they are employed; and industry is expending them at a continually increasing rate. Already coal has been largely replaced by oil, and oil is being used up so fast that East and West alike conceive it necessary to their own prosperity to destroy the industry of the other. And what is true of oil is equally true of other natural resources. Every day, many square miles of forest are turned into newspaper, but there is no known process by which newspaper can be turned into forest. You will say that this need not worry us, since newspapers will be replaced by radio, but radio requires electricity, electricity requires power, and power depends upon raw materials.

I allow nothing for losses by death, but, on the contrary, shall presently take credit four per cent. per annum, for their increase over and above keeping up their own numbers.

In the immense sphere of living things, the obvious rule is violence, a kind of inevitable frenzy which arms all things in mutua funera. Once you leave the world of insensible substances, you find the decree of violent death written on the very frontiers of life. Even in the vegetable kingdom, this law can be perceived: from the huge catalpa to the smallest of grasses, how many plants die and how many are killed!

Truth springs from argument amongst friends.

When technology extends one of our senses, a new translation of culture occurs as swiftly as the new technology is interiorized.

If anyone can be considered the greatest writer who ever lived, it is Shakespeare.

At the end of the Middle Ages, leprosy disappeared from the Western world. In the margins of the community, at the gates of cities, there stretched wastelands which sickness had ceased to haunt but had left sterile and long uninhabitable. For centuries, these reaches would belong to the non-human. From the fourteenth to the seventeenth century, they would wait, soliciting with strange incantations a new incarnation of disease, another grimace of terror, renewed rites of purification and exclusion.

An early morning walk is a blessing for the whole day.

The business of art is no longer the communication of thoughts or feelings which are to be conceptually ordered, but a direct participation in an experience. The whole tendency of modern communication...is towards participation in a process, rather than apprehension of concepts.

The neo-conservative critics of leftist critics of mass culture ridicule the protest against Bach as background music in the kitchen, against Plato and Hegel, Shelley and Baudelaire, Marx and Freud in the drugstore. Instead, they insist on recognition of the fact that the classics have left the mausoleum and come to life again, that people are just so much more educated. True, but coming to life as classics, they come to life as other than themselves; they are deprived of their antagonistic force, of the estrangement which was the very dimension of their truth.

A human being possessed by a belief and not eager to pass it on to others is a phenomenon alien to the earth, where our mania for salvation makes life unbreathable.

Do you ask me whom I have conquered? Neither the Persians, nor the far-off Medes, nor any warlike race that lies beyond the Dahae; not these, but greed, ambition, and the fear of death that has conquered the conquerors of the world.

I know no safe depository of the ultimate powers of the society but the people themselves; and if we think them not enlightened enough to exercise their control with wholesome discretion, the remedy is not to take it from them, but to inform their discretion by education. This is the true corrective of abuses of constitutional power.

It is not my aim to surprise or shock you - but the simplest way I can summarize is to say that there are now in the world machines that think, that learn and that create. Moreover, their ability to do these things is going to increase rapidly until - in a visible future - the range of problems they can handle will be coextensive with the range to which the human mind has been applied.

The most manifest sign of wisdom is a continual cheerfulness; her state is like that in the regions above the moon, always clear and serene.

If there is anything that we wish to change in the child, we should first examine it and see whether it is not something that could better be changed in ourselves.
