A just system must generate its own support.

Even opinion is of force enough to make itself to be espoused at the expense of life.

A man discovers what he is actually worth in this world when he faces society as a man, without money, name, or powerful connections, stripped of all but his native potentialities. He soon finds that nothing has less weight than his human qualities. They are prized so low that the market does not even list them. Strict science, which acknowledges man only as a biological concept, reflects man's lot in the actual world; in himself, man is nothing more than a member of a species. In the eyes of the world, the quality of humanity confers no title to existence, nay, not even a right of sojourn. Such title must be certified by special social circumstances stipulated in documents to be presented on demand.

In the lowest broad strata of the population, equally as in the highest and narrowest, are produced men of every kind of genius; man for man, your chance of genius is as good among the millions as among the units;-and class for class, what must it be! From all classes, not from certain hundreds now but from several millions, whatsoever man the gods had gifted with intellect and nobleness, and power to help his country, could be chosen: O Heavens, could,-if not by Tenpound Constituencies and the force of beer, then by a Reforming Premier with eyes in his head, who I think might do it quite infinitely better. Infinitely better. For ignobleness cannot, by the nature of it, choose the noble: no, there needs a seeing man who is himself noble, cognizant by internal experience of the symptoms of nobleness.

Nothing prints more lively in our minds than something we wish to forget.

And as to you, Sir, treacherous in private friendship (for so you have been to me, and that in the day of danger) and a hypocrite in public life, the world will be puzzled to decide whether you are an apostate or an impostor; whether you have abandoned good principles, or whether you ever had any. 

Nothing is troublesome that we do willingly.

Does anything genuinely beautiful need supplementing? No more than justice does-or truth, or kindness, or humility. Are any of those improved by being praised? Or damaged by contempt? Is an emerald suddenly flawed if no one admires it? Or gold, or ivory, or purple? Lyres? Knives? Flowers? Bushes?

'Tis well to restrain the wicked, and in any case not to join him in his wrong-doing.

I assert once again as a truth to which history as a whole bears witness that men may second their fortune, but cannot oppose it; that they may weave its warp, but cannot break it. Yet they should never give up, because there is always hope, though they know not the end and more towards it along roads which cross one another and as yet are unexplored; and since there is hope, they should not despair, no matter what fortune brings or in what travail they find themselves.

Every living creature commences its existence under a form different from, and simpler than, that which it eventually attains.

The end of history is, alas, also the end of the dustbins of history. There are no longer any dustbins for disposing of old ideologies, old regimes, old values. Where are we going to throw Marxism, which actually invented the dustbins of history? (Yet there is some justice here since the very people who invented them have fallen in.) Conclusion: if there are no more dustbins of history, this is because History itself has become a dustbin. It has become its own dustbin, just as the planet itself is becoming its own dustbin.

The self-surmounter can never put up with the man who has ceased to be dissatisfied with himself.

Men are eager to tread underfoot what they have once too much feared.

When an astronomer tells me that some stellar phenomenon, which his telescope reveals to him at this moment, happened... fifty years ago... I... ask... how he has measured the velocity of light.

But everyone who hears these sayings of Mine, and does not do them, will be like a foolish man who built his house on the sand: and the rain descended, the floods came, and the winds blew and beat on that house; and it fell. And great was its fall.

A book can never be anything more than the impression of its author's thoughts [Ein Buch kann nie mehr seyn, als der Abdruck der Gedanken des Verfassers]. The value of these thoughts lies either in the matter about which he has thought, or in the form in which he develops his matter - that is to say, what he has thought about it.

The guillotine takes life almost without touching the body, just as prison deprives of liberty or a fine reduces wealth. It is intended to apply the law not so to a real body capable of feeling pain as to a juridical subject, the possessor, among other rights, of the right to exist it had to have the abstraction of the law itself.

Once conform, once do what others do because they do it, and a kind of lethargy steals over all the finer senses of the soul.

These left me in no doubt that something was trying to communicate with us, but that direct communication would be counterproductive. It seemed to be an important part of the scheme to create a sense of mystery.

Let him who seeks continue seeking until he finds. When he finds, he will become troubled. When he becomes troubled, he will be astonished, and he will rule over the All.

You have demanded of me, Novatus, that I should write how anger may be soothed, and it appears to me that you are right in feeling especial fear of this passion, which is above all others hideous and wild: for the others have some alloy of peace and quiet, but this consists wholly in action and the impulse of grief, raging with an utterly inhuman lust for arms, blood and tortures, careless of itself provided it hurts another, rushing upon the very point of the sword, and greedy for revenge even when it drags the avenger to ruin with itself.

Suffering is a spiritual thing. It is the most immediate revelation of consciousness, and it may be that our body was given us simply in order that suffering might be enabled to manifest itself. A man who had never known suffering, either in greater or less degree, would scarcely possess consciousness of himself. The child first cries at birth when the air, entering into his lungs and limiting him, seems to say to him: You have to breathe me in order to live!

A people who are still, as it were, but in the gristle, and not yet hardened into the bone of manhood.

I hung my verse in the wind Time and tide their faults will find.

Myths are not descriptions of things, but expressions of a determination to act... A myth cannot be refuted since it is, at bottom, identical with the convictions of a group, being the expression of these convictions in the language of movement.

No one is so modest as not to believe himself a competent amateur sleuth.

The perception of the comic is a tie of sympathy with other men, a pledge of sanity, and protection from those perverse tendencies and gloomy insanities in which fine intellects sometimes lose themselves. A rogue alive to the ludicrous is still convertible.

Childhood lasts all through life. It returns to animate broad sections of adult life.... Poets will help us to find this living childhood within us, this permanent, durable immobile world.

Every rich man is avaricious, in my opinion.

There is no alleviation for the sufferings of mankind except veracity of thought and of action, and the resolute facing of the world as it is, when the garment of make-believe, by which pious hands have hidden its uglier features, is stripped off.

Christianity possesses the great advantage over Judaism of being represented as coming from the mouth of the first Teacher not as a statutory but as a moral religion, and as thus entering into the closest relation with reason so that, through reason, it was able of itself, without historical learning, to be spread at all times and among all peoples with the greatest trustworthiness.

What does man actually know about himself? Is he, indeed, ever able to perceive himself completely, as if laid out in a lighted display case? Does nature not conceal most things from him even concerning his own body in order to confine and lock him within a proud, deceptive consciousness, aloof from the coils of the bowels, the rapid flow of the blood stream, and the intricate quivering of the fibers! She threw away the key.

We should infer in the case of a beautiful dwelling-place that it was built for its owners and not for mice; we ought, therefore, in the same way to regard the universe as the dwelling-place of the gods.

Always to have lived with the nostalgia to coincide with something, but not really knowing with what - it is easy to shift from unbelief to belief, or conversely. But what is there to convert to, and what is there to abjure, in a state of chronic lucidity?

The real struggle is not between East and West, or capitalism and communism, but between education and propaganda.

I have twice gone fishing with rod and line just because other boys asked me to, but this sport was soon made impossible for me by the treatment of the worms that were put on the hook for bait, and the wrenching of the mouths of the fishes that were caught. I gave it up, and even found courage enough to dissuade other boys from going.

Did Romeo and Juliet have a ... "relationship"? The term "relationship" ... betokens a chaste egalitarianism leveling different ranks and degrees of attachment.

Space, subjectively, is the coexistence of perceptions - perceiving two objects at once.

What else is there which you would regret to have taken from you? Friends? But who can be a friend to you? Country? What? Do you think enough of your country to be late to dinner? The light of the sun? You would extinguish it, if you could; for what have you ever done that was fit to be seen in the light?

Why don't I kill myself? If I knew exactly what keeps me from doing so, I should have no more questions to ask myself since I should have answered them all.

What I will be remembered for are the Foundation Trilogy and the Three Laws of Robotics. What I want to be remembered for is no one book, or no dozen books. Any single thing I have written can be paralleled or even surpassed by something someone else has done. However, my total corpus for quantity, quality and variety can be duplicated by no one else. That is what I want to be remembered for.

We admire people to the extent that we cannot explain what they do, and the word "admire" then means "marvel at."

Now in this island of Atlantis there was a great and wonderful empire which had rule over the whole island and several others, and over parts of the continent and, furthermore, the men of Atlantis had subjected the parts of Libya within the columns of Heracles as far as Egypt, and of Europe as far as Tyrrhenia. This vast power, gathered into one, endeavored to subdue at a blow our country and yours and the whole of the region within the straits, and then, Solon, your country shone forth, in the excellence of her virtue and strength, among all mankind.

God, I have said, is the fulfiller, or the reality, of the human desires for happiness, perfection, and immortality. From this it may be inferred that to deprive man of God is to tear the heart out of his breast. But I contest the premises from which religion and theology deduce the necessity and existence of God, or of immortality, which is the same thing. I maintain that desires which are fulfilled only in the imagination, or from which the existence of an imaginary being is deduced, are imaginary desires, and not the real desires of the human heart; I maintain that the limitations which the religious imagination annuls in the idea of God or immortality, are necessary determinations of the human essence, which cannot be dissociated from it, and therefore no limitations at all, except precisely in man's imagination.

There are not two kinds of human being, savage and civilized. There is only the human animal, forever at war with itself.

Most of the texts... preserved from this period come from writers... either... affiliated with the aristocratic party, or... distrustful of democratic or radically democratic institutions.
