It seemed perfectly possible that, in spite of my certainty of my own genius, I might die of some illness, or perhaps even in a street accident, before I had ever glimpsed the meaning of life. My moods of happiness and self-confidence convinced me that I had a "destiny" to become a famous writer, and to be remembered as one of the most important thinkers of the century.

Before either of us knew it, we belonged to each other.

What began as a "Romantic reaction" towards organic wholeness may or may not have hastened the discovery of electro-magnetic waves. But certainly the electro-magnetic discoveries have recreated the simultaneous "field" in all human affairs so that the human family now exists under conditions of a "global village." We live in a single constricted space resonant with tribal drums. So that concern with the "primitive" today is as banal as nineteenth-century concern with "progress," and as irrelevant to our problems. The new electronic interdependence recreates the world in the image of a global village.

If one does not understand a person, one tends to regard him as a fool.

Age may have one side, but assuredly Youth has the other. There is nothing more certain than that both are right, except perhaps that both are wrong. Let them agree to differ; for who knows but what agreeing to differ may not be a form of agreement rather than a form of difference?

The principles of Western liberalism seem no longer to lend themselves to effective action. Deprived of the expressive power, we are awed by it, have a hunger for it, and are afraid of it. Thus we praise the gray dignity of our soft-spoken leaders, but in our hearts we are suckers for passionate outbursts, even when those passionate outbursts are hypocritical and falsely motivated.

They who know the truth are not equal to those who love it, and they who love it are not equal to those who delight in it.

Asked where he came from, he said, "I am a citizen of the world."

Don Quixote made himself ridiculous; but did he know the most tragic ridicule of all, the inward ridicule, the ridiculousness of a man's self to himself, in the eyes of his own soul? Imagine Don Quixote's battlefield to be his own soul; imagine him to be fighting in his soul to save the Middle Ages from the Renaissance, to preserve the treasure of his infancy; imagine him an inward Don Quixote, with a Sancho at his side, inward and heroic too - and tell me if you find anything comic in the tragedy.

Use, do not abuse; as the wise man commands. I flee Epictetus and Petronius alike. Neither abstinence nor excess ever renders man happy.

The students of physical science are not unfrequently told that their pursuits unfit them for the estimation of moral probability. And it may be so, for I am afraid that to those who are accustomed to severe reasoning, either in the province of Science or in that of Law, reasoning from 'moral probability' is apt to be regarded as a process of accumulating inconclusive arguments, in the hope that a great heap of them may, at least, look as firm as one good demonstration.

He is a despicable sage whose wisdom does not profit himself.

Talk of secularism is meaningful when it refers to the weakness of traditional religious belief or the lack of power of churches and other religious bodies. That is what is meant when we say Britain is a more secular country than the United States, and in this sense secularism is an achievable condition. But if it means a type of society in which religion is absent, secularism is a kind of contradiction, for it is defined by what it excludes. Post-Christian secular societies are formed by the beliefs they reject, whereas a society that had truly left Christianity behind would lack the concepts that shaped secular thought.

Every man is fully satisfied that there is such a thing as truth, or he would not ask any question.

Persons who feel themselves to be exiles in this world-and what noble mind, from Empedocles down, has not had that feeling?-are mightily inclined to believe themselves citizens of another.

Neither of us cares a straw for popularity. A proof of this is for example, that, because of aversion to any personality cult, I have never permitted the numerous expressions of appreciation from various countries with which I was pestered during the existence of the International to reach the realm of publicity, and have never answered them, except occasionally by a rebuke. When Engels and I first joined the secret Communist Society we made it a condition that everything tending to encourage superstitious belief in authority was to be removed from the statutes.

Education is the acquisition of the art of the utilisation of knowledge.

Thrasyllus the Cynic begged a drachm of Antigonus. "That," said he, "is too little for a king to give." "Why, then," said the other, "give me a talent." "And that," said he, "is too much for a Cynic (or, for a dog) to receive."

The fact of the religious vision, and its history of persistent expansion, is our one ground for optimism. Apart from it, human life is a flash of occasional enjoyments lighting up a mass of pain and misery, a bagatelle of transient experience.

It must not be supposed that the subjective elements are any less 'real' than the objective elements; they are only less important... because they do not point to anything beyond ourselves...

If human nature were unchangeable, as ignorant people still suppose it to be, the situation would indeed be hopeless.

An old fairy tale has it that science began with the rejection of superstition. In fact it was the rejection of rationalism that gave birth to scientific inquiry. Ancient and medieval thinkers believed the world could be understood by applying first principles. Modern science begins when observation and experiment come first, and the results are accepted even when what they show seems to be impossible.

Civilization gives the barbarian or tribal man an eye for an ear and is now at odds with the electronic world.

I'm afraid of losing my obscurity. Genuineness only thrives in the dark. Like celery.

In a well worn metaphor, a parallel is drawn between the life of man and the metamorphosis of the caterpillar into the butterfly; but the comparison may be more just as well as more novel, if for its former term we take the mental progress of the race. History shows that the human mind, fed by constant accessions of knowledge, periodically grows too large for its theoretical coverings, and bursts them asunder to appear in new habiliments, as the feeding and growing grub, at intervals, casts its too narrow skin and assumes another, itself but temporary. Truly the imago state of Man seems to be terribly distant, but every moult is a step gained, and of such there have been many.

It is sometimes maintained that racial mixture is biologically undesirable. There is no evidence whatever for this view. Nor is there, apparently, any reason to think that Negroes are congenitally less intelligent than white people, but as to that it will be difficult to judge until they have equal scope and equally good social conditions.

The "tragic flaw" is not a detail of characterization, a mere "fly in the ointment", but a structural feature of ordinary consciousness.

That which parents should take care of... is to distinguish between the wants of fancy, and those of nature.

In conclusion, then, no satisfactory interpretation of quantum mechanics exists today. The questions posed by the confrontation between the Copenhagen interpretation and the hidden variable theorists go to the very foundations of microphysics, but the answers given by hidden variable theorists and Copenhagenists are alike unsatisfactory. Human curiosity will not rest until those questions are answered, but whether they will be answered by conceptual innovations within the framework of the present theory or only within the framework of an as yet unforeseen theory is unknown. The first step toward answering them has been attempted here. It is the modest but essential step of becoming clear on the nature and magnitude of the difficulties.

Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement: and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it. This famous statement has produced many paraphrases and variants: Those who cannot learn from history are doomed to repeat it. Those who do not remember their past are condemned to repeat their mistakes. Those who do not read history are doomed to repeat it. Those who fail to learn from the mistakes of their predecessors are destined to repeat them. Those who do not know history's mistakes are doomed to repeat them.

It is easy to see that the existing generation are conspiring with a beneficence, which, in its working for coming generations, sacrifices the passing one, which infatuates the most selfish men to act against their private interest for the public welfare. We build railroads, we know not for what or for whom; but one thing is certain, that we who build will receive the very smallest share of benefit. Benefit will accrue; they are essential to the country, but that will be felt not until we are no longer countrymen. We do the like in all matters: - 'Man's heart the Almighty to the Future setBy secret and inviolable springs.'

And we feel that the hero has lived all the details of this night like annunciations, promises, or even that he lived only those that were promises, blind and deaf to all that did not herald adventure. We forget that the future was not yet there; the man was walking in the night without forethought, a night which offered him a choice of dull rich prizes, and he did not make his choice.

The soul is the prison of the body.

Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets.

I spoke after Sasha, for an hour. I discussed the farce of a government undertaking to carry democracy abroad by suppressing the last vestiges of it at home. I took up the contention of Judge Mayer that only such ideas are permissible as are "within the law." Thus he had instructed the jurymen when he had asked them if they were prejudiced against those who propagate unpopular ideas. I pointed out that there had never been an ideal, however humane and peaceful, which in its time had been considered "within the law." I named Jesus, Socrates, Galileo, Giordano Bruno. "Were they 'within the law"?" I asked. "And the men who set America free from British rule, the Jeffersons and the Patrick Henrys? The William Lloyd Garrisons, the John Browns, the David Thoreaus and Wendell Phillipses-were they within the law?"

The 'Enlightenment', which discovered the liberties, also invented the disciplines.

Every pitifulest whipster that walks within a skin has had his head filled with the notion that he is, shall be, or by all human and divine laws ought to be, 'happy.' His wishes, the pitifulest whipster's, are to be fulfilled for him; his days, the pitifulest whipster's, are to flow on in an ever-gentle current of enjoyment, impossible even for the gods. The prophets preach to us, Thou shalt be happy; thou shalt love pleasant things, and find them. The people clamor, Why have we not found pleasant things? ...God's Laws are become a Greatest Happiness Principle. There is no religion; there is no God; man has lost his soul.

But the truth is that my work - I was going to say my mission - is to shatter the faith of men here, there, and everywhere, faith in affirmation, faith in negation, and faith in abstention in faith, and this for the sake of faith in faith itself; it is to war against all those who submit, whether it be to Catholicism, or to rationalism, or to agnosticism; it is to make all men live the life of inquietude and passionate desire.

Among the smaller duties of life I hardly know any one more important than that of not praising where praise is not due.

This same Man-of-Letters Hero must be regarded as our most important modern person. He, such as he may be, is the soul of all.

We shouldn't teach great books; we should teach a love of reading. Knowing the contents of a few works of literature is a trivial achievement. Being inclined to go on reading is a great achievement.

Rohde became more and more firmly bound to the bourgeois world, its institutions and accepted opinions. ... The contrast between the two natures makes Rohde and Nietzsche exemplary representatives of two distinctive worlds. In their youth they both live in the realm of boundless possibilities and feel an affinity through the exuberance of their noble aspirations. Subsequently they go in opposite directions. Nietzsche remains young, leaving concrete reality as his task assumes existential import. Rohde grows old, bourgeois, stable, and skeptical. Hence courage is a fundamental trait in Nietzsche, plaintive self-irony in Rohde. ... Rohde retained the interests but not the attitudes of his youth; he looked to the world of the Greeks for the object of his contemplation rather than the norm of obligation.

How good would it be if one could die by throwing oneself into an infinite void.

Philosophy stands in the same relation to the study of the actual world as masturbation to sexual love.

The most important part of education - to teach the meaning of to know (in the scientific sense). The last statement in her notebook

How is it possible that a being with such sensitive jewels as the eyes, such enchanted musical instruments as the ears, and such fabulous arabesque of nerves as the brain can experience itself anything less than a god.

An irrational fear should never be simply let alone, but should be gradually overcome by familiarity with its fainter forms.

Sound knowledge respecting the habits and mode of life of the man-like Apes has been even more difficult of attainment than correct information regarding their structure.

He will through life be master of himself and a happy man who from day to day can have said, "I have lived: tomorrow the Father may fill the sky with black clouds or with cloudless sunshine."
