Coexistent polarities are fundamentally identical.

When shall we see poets born? After a time of disasters and great misfortunes, when harrowed nations begin to breathe again. And then, shaken by the terror of such spectacles, imaginations will paint things entirely strange to those who have not witnessed them.

Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.

By striving to do the impossible, man has always achieved what is possible. Those who have cautiously done no more than they believed possible have never taken a single step forward.

Free trade consists simply in letting people buy and sell as they want to buy and sell. It is protection that requires force, for it consists in preventing people from doing what they want to do. Protective tariffs are as much applications of force as are blockading squadrons, and their object is the same-to prevent trade. The difference between the two is that blockading squadrons are a means whereby nations seek to prevent their enemies from trading; protective tariffs are a means whereby nations attempt to prevent their own people from trading. What protection teaches us, is to do to ourselves in time of peace what enemies seek to do to us in time of war.

Adeimantus, in what amounts to an accusation of Socrates, asserts that the philosophers appear to be either useless or vicious. Plato, as I have suggested, teaches that ultimately this is an appearance that cannot be reversed, and this insures the philosophers' permanent marginality. They appear as useless because they are. They are neither artisans, nor statesmen, nor rhetoricians. They are idlers who contribute nothing to security or posterity. Their peculiar contemplative pleasures are not accessible to the majority of mankind, and they do not provide for the popular pleasures as do the poets.

In a valiant suffering for others, not in a slothful making others suffer for us, did nobleness ever lie.

Be afraid of the Chinese. I mean, the Chinese shoot down satellites in space; they hack into Google's computers; the Osama bin Laden people can't make their underwear blow up.

Grief and disappointment give rise to anger, anger to envy, envy to malice, and malice to grief again, till the whole circle be completed.

It costs a beautiful person no exertion to paint her image on our eyes; yet how splendid is that benefit! It costs no more for a wise soul to convey his quality to other men.

What anxiety when one is not sure of one's doubts or wonders: are these actually doubts?

Show me that the good in life does not depend upon life's length, but upon the use we make of it; also, that it is possible, or rather usual, for a man who has lived long to have lived too little. Say to me when I lie down to sleep: "You may not wake again!" And when I have waked: "You may not go to sleep again!" Say to me when I go forth from my house: "You may not return!" And when I return: "You may never go forth again!"

Just as Marx used to say about the French Marxists of the late 'seventies: All I know is that I am not a Marxist.

I cannot help fearing that men may reach a point where they look on every new theory as a danger, every innovation as a toilsome trouble, every social advance as a first step toward revolution, and that they may absolutely refuse to move at all.

Recalling all the erroneous things that doctors have been able to say about sex or madness does us a fat lot of good. I think that what is currently politically important is to determine the regime of verediction established at a given moment ... on the basis of which you can now recognize, for example, that doctors in the nineteenth century said so many stupid things about sex. ... It is not so much the history of the true or the history of the false as the history of verediction which has a political significance.

Wherever you encounter truth, look upon it as Christianity.

The content or time-clothing of any medium or culture is the preceding medium or culture.

Live among men as if God beheld you; speak with God as if men were listening.

The present state of France was ten times worse than a tyranny. The new constitution was said to be an experiment but the assertion was not true. It had already been tried, and had been found to be only productive of evils. They would go on from tyranny to tyranny, from oppression to oppression, till at last the whole system would terminate in the destruction of that miserable and deluded people... He sincerely hoped that no member of that House would ever barter the constitution of this country, the eternal jewel of their souls, for a wild and visionary system, which could only lead to confusion and disorder.

It is a great good fortune, as Stendhal said, for one "to have his passion as a profession."

I say, it is the everlasting privilege of the foolish to be governed by the wise; to be guided in the right path by those who know it better than they. This is the first "right of man;" compared with which all other rights are as nothing.

There are ages in which the rational man and the intuitive man stand side by side, the one in fear of intuition, the other with scorn for abstraction. The latter is just as irrational as the former is inartistic. They both desire to rule over life: the former, by knowing how to meet his principle needs by means of foresight, prudence, and regularity; the latter, by disregarding these needs and, as an "overjoyed hero," counting as real only that life which has been disguised as illusion and beauty.

Nature forms us for ourselves, not for others; to be, not to seem.

One would have to be as unenlightened as an angel or an idiot to imagine that the human escapade could turn out well.

Consciousness must essentially cover an interval of time; for if it did not, we could gain no knowledge of time, and not merely no veracious cognition of it, but no conception whatever. We are therefore, forced to say that we are immediately conscious through an infinitesimal interval of time.

In recent times it has been fashionable to talk of the levelling of nations, of the disappearance of different races in the melting-pot of contemporary civilization. I do not agree with this opinion, but its discussion remains another question. Here it is merely fitting to say that the disappearance of nations would have impoverished us no less than if all men had become alike, with one personality and one face. Nations are the wealth of mankind, its collective personalities; the very least of them wears its own special colours and bears within itself a special facet of divine intention.

The battling Reformer too is, from time to time, a needful and inevitable phenomenon. Obstructions are never wanting: the very things that were once indispensable furtherances become obstructions; and need to be shaken off, and left behind us,-a business often of enormous difficulty.

He who takes not counsel of the Unseen and Silent, from him will never come real visibility and speech.

The big advantage of being a chemistry major was the freedom to be tasteless.

Let great authors have their due, as time, which is the author of authors, be not deprived of his due, which is, further and further to discover truth.

A confession has to be part of your new life.

What is not supposed to be my concern! First and foremost, the Good Cause, then God's cause, the cause of mankind, of truth, of freedom, of humanity, of justice; further, the cause of my people, my prince, my fatherland; finally, even the cause of Mind, and a thousand other causes. Only my cause is never to be my concern. "Shame on the egoist who thinks only of himself!"

For every man the world is as fresh as it was at the first day, and as full of untold novelties for him who has the eyes to see them.

The bourgeois public sphere may be conceived above all as the sphere of private people come together as a public; they soon claimed the public sphere regulated from above against the public authorities themselves, to engage them in a debate over the general rules governing relations in the basically privatized but publicly relevant sphere of commodity exchange and social labor.

Administration is not unlike play-acting. The task of the good actor is to know and play his role, although different roles may differ greatly in content. The effectiveness of the performance will depend on the effectiveness of the play and the effectiveness with which it is played. The effectiveness of the administrative process will vary with the effectiveness of the organization and the effectiveness with which its members play their parts.

What is not good for the swarm is not good for the bee.

It is not you talking. Nor is it your race only which shouts within you, for all the innumerable races of mankind shout and rush within you: white, yellow, black. Free yourself from race also; fight to live through the whole struggle of man.

A people cannot be free otherwise than at the individual's expense; for it is not the individual that is the main point in this liberty, but the people. The freer the people, the more bound the individual; the Athenian people, precisely at its freest time, created ostracism, banished the atheists, poisoned the most honest thinker.

Tragic paradox of freedom: the mediocre men who alone make its exercise possible cannot guarantee its duration.

Since my earliest childhood a barb of sorrow has lodged in my heart. As long as it stays I am ironic - if it is pulled out I shall die.

The way of learning is none other than finding the lost mind.

The aim of science is to seek the simplest explanations of complex facts. We are apt to fall into the error of thinking that the facts are simple because simplicity is the goal of our quest. The guiding motto in the life of every natural philosopher should be, "Seek simplicity and distrust it."

Fleeing from a life of constant insecurity and forced mobility is good preparation for dealing with and resisting the typical forms of exploitation of immaterial labor.

Exchange value forms the substance of money, and exchange value is wealth.
