Classical science was based upon the belief that it is possible to formulate both the position and velocity at one time of any given particle. It followed that knowledge of the position and velocity of a given number of particles would enable the future behavior of the whole collection to be accurately predicted. The principle of Heisenberg is that given the determination of position, its velocity can be stated only as of a certain order of probability, while if its velocity is determined the correlative factor of position can be stated only as of a certain order of probability. Both cannot be determined at once, from which it follows necessarily that the future of the whole collection cannot possibly be foretold except in terms of some order of probability.

Everyone has a goal which appears to be great, at least to himself, and is great when deepest conviction, the innermost voice of the heart, pronounces it great. ... This voice, however, is easily drowned out, and what we thought to be inspiration may have been created by the fleeting moment and again perhaps destroyed by it. ... We must seriously ask ourselves, therefore, whether we are really inspired about a vocation, whether an inner voice approves of it, or whether the inspiration was a deception, whether that which we took as the Deity's calling to us was self-deceit. But how else could we recognize this except by searching for the source of our inspiration?

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.

There is needed, no doubt, a body of servants (ministerium) of the invisible church, but not officials (officiales), in other words, teachers but not dignitaries, because in the rational religion of every individual there does not yet exist a church as a universal union (omnitudo collectiva).

Look for yourself, and you will find in the long run only hatred, loneliness, despair, rage, ruin, and decay. But look for Christ and you will find Him, and with Him everything else thrown in.

It is sweet and honorable to die for one's country.

A lot of people recoil from the word "drugs" - which is understandable given today's noxious street drugs and their uninspiring medical counterparts. Yet even academics and intellectuals in our society typically take the prototypical dumb drug, ethyl alcohol. If it's socially acceptable to take a drug that makes you temporarily happy and stupid, then why not rationally design drugs to make people perpetually happier and smarter? Presumably, in order to limit abuse-potential, one would want any ideal pleasure drug to be akin - in one limited but important sense - to nicotine, where the smoker's brain finely calibrates its optimal level: there is no uncontrolled dose-escalation.

What is called an acute knowledge of human nature is mostly nothing but the observer's own weaknesses reflected back from others.

Each of us is born with a share of purity, predestined to be corrupted by our commerce with mankind, by that sin against solitude.

Doth the reality of sensible things consist in being perceived? or, is it something distinct from their being perceived, and that bears no relation to the mind?

I find that the best goodness I have has some tincture of vice.

Communism differs from all previous movements in that it overturns the basis of all earlier relations of production and intercourse, and for the first time consciously treats all natural premises as the creatures of hitherto existing men, strips them of their natural character and subjugates them to the power of the united individuals. Its organisation is, therefore, essentially economic, the material production of the conditions of this unity; it turns existing conditions into conditions of unity. The reality, which communism is creating, is precisely the true basis for rendering it impossible that anything should exist independently of individuals, insofar as reality is only a product of the preceding intercourse of individuals themselves.

Most books belong to the house and streets only, and in the fields their leaves feel very thin.

Outside the academic establishment, the "far-reaching change in all our habits of thought" is more serious. It serves to coordinate ideas and goals with those exacted by the prevailing system, to enclose them in the system, and to repel those which are irreconcilable with the system. The reign of such a one-dimensional reality does not mean that materialism rules, and that the spiritual, metaphysical, and bohemian occupations are petering out. On the contrary, there is a great deal of "Worship together this week," "Why not try God," Zen, existentialism, and beat ways of life, etc. But such modes of protest and transcendence are no longer contradictory to the status quo and no longer negative. They are rather the ceremonial part of practical behaviorism, its harmless negation, and are quickly digested by the status quo as part of its healthy diet.

I do not believe that woman will make politics worse; nor can I believe that she could make it better. If, then, she cannot improve on man's mistakes, why perpetrate the latter?

If you are going to be a writer, you must be paranoid. The thing is, in the arts if you don't overreact, you fall asleep.

It is for the sake of order that I seduced Clytemnestra, for the sake of order that I killed my king. I wanted for order to rule and that it rule through me. I have lived without desire, without love, without hope: I made order. Oh! terrible and divine passion!

I have never in my life met a man like him for noble simplicity, and boundless truthfulness. I understood from the way he talked that anyone who chose could deceive him, and that he would forgive anyone afterwards who had deceived him, and that was why I grew to love him.

Wealth begins in a tight roof that keeps the rain and wind out; in a good pump that yields you plenty of sweet water; in two suits of clothes, so to change your dress when you are wet; in dry sticks to burn; in a good double-wick lamp; and three meals; in a horse, or a locomotive, to cross the land; in a boat to cross the sea; in tools to work with; in books to read; and so, in giving, on all sides, by tolls and auxiliaries, the greatest possible extension to our powers, as if it added feet, and hands, and eyes, and blood, length to the day, and knowledge, and good-will.Wealth begins with these articles of necessity.

The growth of the mind is the widening of the range of consciousness, and ... each step forward has been a most painful and laborious achievement.

Men may one day feel that they are partakers of a common nature, and that true freedom and perfect equity, like food and air, are pregnant with benefit to every constitution.

The vicious circle of dread of war which leads the nations to arm themselves for self-protection, with the result that bloated armaments ultimately lead to the war which they were intended to avert, can be broken in either of two conceivable ways. There might arise a unique world power, brought into being by the unification of all those now in possession of weapons, and equipped with the capacity to forbid the lesser and unarmed nations to make war. On the other hand, it may arise by the working of a fate to us still inscrutable which, out of ruin, will disclose a way towards the development of a new human being. To will the discovery of this way would be blind impotence, but those who do not wish to deceive themselves will be prepared for the possibility.

I do not know, my listener, what your crime, your guilt, your sins are, but surely we are all more or less of the guilt of loving only little. Take comfort, then, in these words just as I take comfort in them.

When Confucius and the Indian Scriptures were made known, no claim to monopoly of ethical wisdom could be thought of... It is only within this century [the 1800 's] that England and America discovered that their nursery tales were old German and Scandinavian stories; and now it appears that they came from India, and are therefore the property of all the nations.

Perhaps there is nobody who would sacrifice his life for the sake of maintaining that the three angles of a triangle are together equal to two right angles, for such a truth does not demand the sacrifice of our life; but, on the other hand, there are many who have lost their lives for the sake of maintaining their religious faith. Indeed, it is truer to say that martyrs make faith than that faith makes martyrs. For faith is not the mere adherence of the intellect to an abstract principle; it is not the recognition of a theoretical truth, the process in which the will merely sets in motion our faculty of comprehension; faith is an act of the will - it is a movement of the soul towards a practical truth, towards a person, towards something that makes us not merely comprehend life, but that makes us live.

The characteristic activity of science is not construction, but induction. The more often something has occurred in the past, the more certain that it will in all the future. Knowledge relates solely to what is and to its recurrence. New forms of being, especially those arising from the historical activity of man, lie beyond empiricist theory. Thoughts which are not simply carried over from the prevailing pattern of consciousness, but arise from the aims and resolves of the individual, in short, all historical tendencies that reach beyond what is present and recurrent, do not belong to the domain of science.

To have a great man for an intimate friend seems pleasant to those who have never tried it; those who have, fear it.

Of all the ways whereby children are to be instructed, and their manners formed, the plainest, easiest, and most efficacious, is, to set before their eyes the examples of those things you would have them do, or avoid; which, when they are pointed out to them, in the practice of persons within their knowledge, with some reflections on their beauty and unbecomingness, are of more force to draw or deter their imitation, than any discourses which can be made to them.

Becoming a vegetarian is not merely a symbolic gesture. Nor is it an attempt to isolate oneself from the ugly realities of the world, to keep oneself pure and so without responsibility for the cruelty and carnage all around. Becoming a vegetarian is a highly practical and effective step one can take toward ending both the killing of nonhuman animals and the infliction of suffering upon them.

It is only he who is possessed of the most complete sincerity that can exist under heaven, who can give its full development to his nature. Able to give its full development to his own nature, he can do the same to the nature of other men. Able to give its full development to the nature of other men, he can give their full development to the natures of animals and things. Able to give their full development to the natures of creatures and things, he can assist the transforming and nourishing powers of Heaven and Earth. Able to assist the transforming and nourishing powers of Heaven and Earth, he may with Heaven and Earth form a ternion.

The charlatan takes very different shapes according to circumstances; but at bottom he is a man who cares nothing about knowledge for its own sake, and only strives to gain the semblance of it that he may use it for his own personal ends, which are always selfish and material.

The superior man, extensively studying all learning, and keeping himself under the restraint of the rules of propriety, may thus likewise not overstep what is right.

I came to set fire to the earth, and I wish it were already on fire!

If the passion for truthfulness is merely controlled and stilled without being satisfied, it will kill the activities it is supposed to support. This may be one of the reasons why, at the present time, the study of the humanities runs a risk of sliding from professional seriousness, through professionalization, to a finally disenchanted careerism.

Philosophy is in history, and is never independent of historical discourse. But for the tacit symbolism of life it substitutes, in principle, a conscious symbolism; for a latent meaning, one that is manifest. It is never content to accept its historical situation. It changes this situation by revealing it to itself.

The effect of liberty to individuals is, that they may do what they please: we ought to see what it will please them to do, before we risk congratulations.

A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.

Primitive superstition lies just below the surface of even the most tough-minded individuals, and it is precisely those who most fight against it who are the first to succumb to its suggestive effects.

First of all: what is work? Work is of two kinds: first, altering the position of matter at or near the earth's surface relatively to other such matter; second, telling other people to do so. The first kind is unpleasant and ill paid; the second is pleasant and highly paid.

Everything comes in time to him who knows how to wait.

How shall the dead arise, is no question of my faith; to believe only possibilities, is not faith, but mere philosophy.

Power and violence are opposites; where the one rules absolutely, the other is absent. Violence appears where power is in jeopardy, but left to its own course it ends in power's disappearance.

This is the ideal world, a perfect world of equality, fraternity, harmony, welfare, and justice.

The will is the living principle of the rational soul, is indeed itself reason, when purely and simply apprehended. That reason is itself active, means, that the pure will, as such, rules and is effectual. The infinite reason alone lies immediately and entirely in the purely spiritual order. The finite being lives necessarily at the same time in a sensuous order; that is to say, in one which presents to him other objects than those of pure reason; a material object, to be advanced by instruments and powers, standing indeed under the immediate command of the will, but whose efficacy is conditional also on its own natural laws.

It would be better to be without the Shu-King than to believe every word of it.

A scheme is unjust when the higher expectations, one or more of them, are excessive. If these expectations were decreased, the situation of the less favored would be improved.

Individuality, conceived as a temporal development involves uncertainty, indeterminacy, or contingency. Individuality is the source of whatever is unpredictable in the world.

Think about the strangeness of today's situation. Thirty, forty years ago, we were still debating about what the future will be: communist, fascist, capitalist, whatever. Today, nobody even debates these issues. We all silently accept global capitalism is here to stay. On the other hand, we are obsessed with cosmic catastrophes: the whole life on earth disintegrating, because of some virus, because of an asteroid hitting the earth, and so on. So the paradox is, that it's much easier to imagine the end of all life on earth than a much more modest radical change in capitalism.

Furthermore, when citizens are all almost equal, it becomes difficult for them to defend their independence against the aggressions of power.
