I do not forgive myself for being born. It is as if, creeping into this world, I had profaned a mystery, betrayed some momentous pledge, committed a fault of nameless gravity. Yet in a less assured mood, birth seems a calamity I would be miserable not having known.

The pathfinders of modern thought did not derive what is good from the law. ... Their role in history was not that of adapting their words and actions to the text of old documents or generally accepted doctrines: they themselves created the documents and brought about the acceptance of their doctrines.

What pride to discover that nothing belongs to you - what a revelation.

May not the absolute and perfect eternal happiness be an eternal hope, which would die if it were realized? Is it possible to be happy without hope? And there is no place for hope once possession has been realized, for hope, desire, is killed by possession. May it not be, I say, that all souls grow without ceasing, some in a greater measure than others, but all having to pass some time through the same degree of growth, whatever that degree may be, and yet without ever arriving at the infinite, at God, to whom they continually approach? Is not eternal happiness an eternal hope, with its eternal nucleus of sorrow in order that happiness shall not be swallowed up in nothingness?

It is the most advanced industrial society which feels most directly threatened by the rebellion, because it is here that the social necessity of repression and alienation, of servitude and heteronomy is most transparently unnecessary, and unproductive in terms of human progress. Therefore the cruelty and violence mobilized in the struggle against the threat, therefore the monotonous regularity with which the people are made familiar with, and accustomed to inhuman attitudes and behavior-to wholesale killing as patriotic act.

Mathematical Analysis is... the true rational basis of the whole system of our positive knowledge.

Though love repine, and reason chafe, There came a voice without reply, - "'T is man's perdition to be safe When for the truth he ought to die."

And O! how the mind is here washed clean of all its early ingrafted Jewish superstition ! It is the most profitable and elevating reading which is possible in the world. It has been the solace of my life, and will be the solace of my death.

Whatever you do, He will make good of it. But not the good He had prepared for you if you had obeyed him.

The guiding question of Marx's analysis was, How does capitalist society supply its members with the necessary use-values? And the answer disclosed a process of blind necessity, chance, anarchy and frustration. The introduction of the category of use-value was the introduction of a forgotten factor, forgotten, that is, by the classical political economy which was occupied only with the phenomenon of exchange value. In the Marxian theory, this factor becomes an instrument that cuts through the mystifying reification of the commodity world.

It must be said that charity can, in no way, exist along with mortal sin.

Every living creature is happy when he fulfills his destiny, that is, when he realizes himself, when he is being that which in truth he is. For this reason, Schlegel, inverting the relationship between pleasure and destiny, said, "We have a genius for what we like." Genius, man's superlative gift for doing something, always carries a look of supreme pleasure.

It is also crucial to bear in mind the interconnection between the Decalogue... and its modern obverse, the celebrated 'human Rights'. As the experience of our post-political liberal-permissive society amply demonstrates, human Rights are ultimately, at their core, simply Rights to violate the Ten Commandments. 'The right to privacy' — the right to adultery, in secret, where no one sees me or has the right to probe my life. 'The right to pursue happiness and to possess private property' -- the right to steal (to exploit others). 'Freedom of the press and of the expression of opinion' -- the right to lie. 'The right of free citizens to possess weapons' -- the right to kill. And, ultimately, 'freedom of religious belief' — the right to worship false gods.

I react like everyone else, even like those I most despise; but I make up for it by deploring every action I commit, good or bad.

The outsider, Haller says, is a self-divided man; being self-divided, his chief desire is to be unified. He is selfish as a man with a lifelong raging toothache.

It seems to be almost an invariable rule that as real power declines, the symbols of power multiply and intensify in compensation.

One of the most difficult of the philosopher's tasks is to find out where the shoe pinches.

The profit of books is according to the sensibility of the reader. The profoundest thought or passion sleeps as in a mine until an equal mind and heart finds and publishes it.

They're raising the retirement age because they need you to die before collecting what you paid in. Social Security was supposed to support your final years; now it's structured so many won't reach eligibility. Work until death, die before benefits. The greatest retirement heist is happening in plain sight.

The music that can deepest reach, And cure all ill, is cordial speech.

Good order is the foundation of all good things.

Truth, like light, blinds. Falsehood, on the contrary, is a beautiful twilight that enhances every object.

Philosophical knowledge is the knowledge gained by reason from concepts; mathematical knowledge is the knowledge gained by reason from the construction of concepts.

Useless laws weaken the necessary laws.

To call out for the hand of the enemy is a rather extreme measure, yet a better one, I think, than to remain in continual fever over an accident that has no remedy. But since all the precautions that a man can take are full of uneasiness and uncertainty, it is better to prepare with fine assurance for the worst that can happen, and derive some consolation from the fact that we are not sure that it will happen.

... the fight against suffering must be considered a duty, while the right to care for the happiness of others must be considered a privilege confined to the close circle of their friends. ... Pain, suffering, injustice, and their prevention, these are the eternal problems of public morals, the 'agenda' of public policy ...

It is easy to see that this problem can be solved neither in theoretical nor in practical philosophy, but only in a higher discipline, which is the link that combines them, and neither theoretical nor practical, but both at once.

In the root of the word "faith" itself... there is implicit the idea of confidence, of surrender to the will of another, to a person. Confidence is placed only in persons. We trust in Providence, which we perceive as something personal and conscious, not in Fate, which is something impersonal. And thus it is in the person who tells us the truth, in the person that gives us hope, that we believe, not directly or immediately in truth itself or in hope itself.

His obedience is real since he really and truly fulfills his mission, since he runs real risks in order to carry out the beloved's orders. But, on the other hand, it is imaginary because he submits only to a creature of his mind.

For truth itself has not the privilege to be spoken at all times and in all sorts.

As if our birth had at first sundered things, and we had been thrust up through into nature like a wedge, and not till the wound heals and the scar disappears, do we begin to discover where we are, and that nature is one and continuous everywhere.

Most men would feel insulted, if it were proposed to employ them in throwing stones over a wall, and then in throwing them back, merely that they might earn their wages. But many are no more worthily employed now.

If a person tells me he has been to the worst places I have no reason to judge him; but if he tells me it was his superior wisdom that enabled him to go there, then I know he is a fraud.

Machines are worshipped because they are beautiful and valued because they confer power; they are hated because they are hideous and loathed because they impose slavery.

Let them have what instructions you will, and ever so learned lectures of breeding daily inculcated into them, that which will most influence their carriage will be the company they converse with, and the fashion of those about them.

There are two godheads: the world and my independent I. I am either happy or unhappy, that is all. It can be said: good or evil do not exist. A man who is happy must have no fear. Not even in the face of death. Only a man who lives not in time but in the present is happy.

Since he is unable to be the beloved, he will become the lover.

Pay attention to your enemies, for they are the first to discover your mistakes.

Science does not stand still, and neither does philosophy, although the latter has a tendency to walk in circles.

Again, Amyclas the Heracleotean, one of Plato's familiars, and Menæchmus, the disciple, indeed, of Eudoxus, but conversant with Plato, and his brother Dinostratus, rendered the whole of geometry as yet more perfect. But Theudius, the Magnian, appears to have excelled, as well in mathematical disciplines, as in the rest of philosophy. For he constructed elements egregiously, and rendered many particulars more universal. Besides, Cyzicinus the Athenian, flourished at the same period, and became illustrious in other mathematical disciplines, but especially in geometry. These, therefore, resorted by turns to the Academy, and employed themselves in proposing common questions.

The idea of Christ is much older than Christianity.

"What is meant by saying that my choice of which way to walk home after the lecture is ambiguous and matter of chance?...It means that both Divinity Avenue and Oxford Street are called but only one, and that one either one, shall be chosen.

Some say that the body is the "tomb" of the soul, their notion being that the soul is buried in the present life; and again, because by its means the soul gives any signs which it gives, it is for this reason also properly called "sign". But I think it most likely that the Orphic poets gave this name, with the idea that the soul is undergoing punishment for something; they think it has the body as an enclosure to keep it safe, like a prison, and this is, as the name itself denotes, the "safe" for the soul, until the penalty is paid, and not even a letter needs to be changed.

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.

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.

What man calls Absolute Being, his God, is his own being. The power of the object over him is therefore the power of his own being. Thus, the power of the object of feeling is the power of feeling itself; the power of the object of reason is the power of reason itself; and the power of the object of will is the power of will itself.

There is more to a science fiction story than the science it contains.

A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.

There is no mystery in humans creation. Will performs this miracle. But at least there is no true creation without a secret.

If I had followed the multitude, I should not have studied philosophy.
