Civil government, so far as it is instituted for the security of property, is in reality instituted for the defence of the rich against the poor, or of those who have some property against those who have none at all.

The greatest improvement in the productive powers of labour, and the greatest part of skill, dexterity, and judgment with which it is any where directed, or applied, seem to have been the effects of the division of labour.

Through laziness and cowardice a large part of mankind, even after nature has freed them from alien guidance, gladly remain immature. It is because of laziness and cowardice that it is so easy for others to usurp the role of guardians. It is so comfortable to be a minor!

The bitterest tragic element in life to be derived from an intellectual source is the belief in a brute Fate or Destiny.

How can it be that mathematics, being, after all, a product of human thought which is independent of experience, is so admirably appropriate to the objects of reality? Is human reason, then, without experience, merely by taking thought, able to fathom the properties of real things?

Theory is taught so as to make the student believe that he or she can become a Marxist, a feminist, an Afrocentrist, or a deconstructionist with about the same effort and commitment required in choosing items from a menu.

Falling in love is the one illogical adventure, the one thing of which we are tempted to think as supernatural, in our trite and reasonable world. The effect is out of all proportion with the cause. Two persons, neither of them, it may be, very amiable or very beautiful, meet, speak a little, and look a little into each other's eyes. That has been done a dozen or so of times in the experience of either with no great result. But on this occasion all is different. They fall at once into that state in which another person becomes to us the very gist and centrepoint of God's creation, and demolishes our laborious theories with a smile; in which our ideas are so bound up with the one master-thought that even the trivial cares of our own person become so many acts of devotion, and the love of life itself is translated into a wish to remain in the same world with so precious and desirable a fellow-creature.

Once for all, then, a short precept is given thee: Love, and do what thou wilt: whether thou hold thy peace, through love hold thy peace; whether thou cry out, through love cry out; whether thou correct, through love correct; whether thou spare, through love do thou spare: let the root of love be within, of this root can nothing spring but what is good.

Words that everyone once used are now obsolete, and so are the men whose names were once on everyone's lips: Camillus, Caeso, Volesus, Dentatus, and to a lesser degree Scipio and Cato, and yes, even Augustus, Hadrian, and Antoninus are less spoken of now than they were in their own days. For all things fade away, become the stuff of legend, and are soon buried in oblivion. Mind you, this is true only for those who blazed once like bright stars in the firmament, but for the rest, as soon as a few clods of earth cover their corpses, they are 'out of sight, out of mind.' In the end, what would you gain from everlasting remembrance? Absolutely nothing. So what is left worth living for? This alone: justice in thought, goodness in action, speech that cannot deceive, and a disposition glad of whatever comes, welcoming it as necessary, as familiar, as flowing from the same source and fountain as yourself.

Relativity theory forced the abandonment, in principle, of absolute space and absolute time.

What is it that we humans depend on? We depend on our words... Our task is to communicate experience and ideas to others. We must strive continually to extend the scope of our description, but in such a way that our messages do not thereby lose their objective or unambiguous character ... We are suspended in language in such a way that we cannot say what is up and what is down. The word "reality" is also a word, a word which we must learn to use correctly.

Yes, there was an element of abstraction and unreality in misfortune. But when an abstraction starts to kill you, you have to get to work on it.

But the best demonstration by far is experience, if it go not beyond the actual experiment.

We, who are dying, are doing better, than they, who will live. For Crete doesn't need householders, she needs madmen like us. These madmen make Crete immortal.

Eloquence may strike the ear, but the language of poverty strikes the heart; the first may charm like music, but the second alarms like a knell. 

It is sometimes said, common sense is very rare.

Only what we have not accomplished and what we could not accomplish matters to us, so that what remains of a whole life is only what it will not have been.

Bold ideas, unjustified anticipations, and speculative thought, are our only means for interpreting nature: our only organon, our only instrument, for grasping her. And we must hazard them to win our prize. Those among us who are unwilling to expose their ideas to the hazard of refutation do not take part in the scientific game.

For every one feels to what purpose he can use his own powers. Before the horns of a calf appear and sprout from his forehead, he butts with them when angry, and pushes passionately.

We live, in fact, in a world starved for solitude, silence, and privacy: and therefore starved for meditation and true friendship.

The law of causality, I believe, like much that passes muster among philosophers, is a relic of a bygone age, surviving, like the monarchy, only because it is erroneously supposed to do no harm.

I think they do it to pass the time, nothing more. But time is too large, it can't be filled up. Everything you plunge into it is stretched and disintegrates.

To be aware of limitations is already to be beyond them.

Let each look to his own heart: let him not keep hatred against his brother for any hard word; on account of earthly contention let him not become earth.

Men never respect what they have made themselves. This is why an elective king never possesses the moral power of a hereditary sovereign, because he is not noble enough, that is to say he does not possess that kind of greatness independent of men and that is the work of time.

Reaching and understanding is the process of bringing about an agreement on the presupposed basis of validity claims that are mutually recognized.

In fact writing a computer program is a pretty good way to summarize knowledge about any set of rules.

For remember that in general we don't use language according to strict rules - it hasn't been taught us by means of strict rules, either.

It doesn't matter that it can't last, that we don't find it more often. To know that there is such perfection, that there has been such perfection - it is worth living for. It exists. It has been - it is. One can contemplate it and feel complete peace.

There is but one way to bring about the triumph of liberty, of justice, and of peace in Europe's international relations, to make civil war impossible between the different peoples who make up the European family; and that is the formation of the United States of Europe.

Bourgeois sport wants to differentiate itself strictly from play. Its bestial seriousness consists in the fact that instead of remaining faithful to the dream of freedom by getting away from purposiveness, the treatment of play as a duty puts it among useful purposes and thereby wipes out the trace of freedom in it. This is particularly valid for contemporary mass music. It is only play as a repetition of prescribed models, and the playful release from responsibility which is thereby achieved does not reduce at all the time devoted to duty except by transferring the responsibility to the models, the following of which one makes into a duty for himself.

As a black woman interested in feminist movement, I am often asked whether being black is more important than being a woman; whether feminist struggle to end sexist oppression is more important than the struggle to racism or vice versa. All such questions are rooted in competitive either/or thinking, the belief that the self is formed in opposition to an other. ... Most people are socialized to think in terms of opposition rather than compatibility. Rather than seeing anti-racist work as totally compatible with working to end sexist oppression, they often see them as two movements competing for first place.

Hegel ... proceeds abstractly from the pre-existence of the intellect. ... He does not appeal to the intellect within us.

A book is a small cog in a much more complex, external machinery. Writing is a flow among others; it enjoys no special privilege and enters into relationships of current and counter-current, of back-wash with other flows - the flows of shit, sperm, speech, action, eroticism, money, politics, etc. Like Bloom, writing on the sand with one hand and masturbating with the other - two flows in what relationship?

The percept takes priority of the concept.

Nothing becomes so offensive so quickly as grief. When fresh it finds someone to console it, but when it becomes chronic, it is ridiculed and rightly.

When the real is no longer what it was, nostalgia assumes its full meaning. "The Precession of Simulacra,"

Men must be governed by those laws which they love. Where thirty millions are to be governed by a few thousand men, the government must be established by consent, and must be congenial to the feelings and to the habits of the people. That which creates tyranny is the imposition of a form of government contrary to the will of the governed: and even a free and equal plan of government, would be considered as despotic by those who desired to have their old laws and their ancient system.

...undefiled by pleasures, invulnerable to any pain, untouched by arrogance, unaffected by meanness, an athlete in the greatest of all contests-the struggle not to be overwhelmed by anything that happens.

And why were those haughty [French] nobles destroyed with that utter destruction? Why were they scattered over the face of the earth, their titles abolished, their escutcheons defaced, their parks wasted, their palaces dismantled, their heritage given to strangers? Because they had no sympathy with the people, no discernment of the signs of their time; because, in the pride and narrowness of their hearts, they called those whose warnings might have saved them theorists and speculators; because they refused all concession till the time had arrived when no concession would avail.

Amid this life based on coercion, one and the same thought constantly emerged among different nations, namely, that in every individual a spiritual element is manifested that gives life to all that exists, and that this spiritual element strives to unite with everything of a like nature to itself, and attains this aim through love.

Have ye not read what David did, when he was an hungred, and they that were with him; How he entered into the house of God, and did eat the shewbread, which was not lawful for him to eat, neither for them which were with him, but only for the priests? Or have ye not read in the law, how that on the sabbath days the priests in the temple profane the sabbath, and are blameless? But I say unto you, That in this place is one greater than the temple. But if ye had known what this meaneth, I will have mercy, and not sacrifice, ye would not have condemned the guiltless.

My purpose is to set forth a very new science dealing with a very ancient subject. There is, in nature, perhaps nothing older than motion, concerning which the books written by philosophers are neither few nor small; nevertheless I have discovered by experiment some properties of it which are worth knowing and which have not hitherto been either observed or demonstrated. Some superficial observations have been made, as, for instance, that the free motion [naturalem motum] of a heavy falling body is continuously accelerated; but to just what extent this acceleration occurs has not yet been announced; for so far as I know, no one has yet pointed out that the distances traversed, during equal intervals of time, by a body falling from rest, stand to one another in the same ratio as the odd numbers beginning with unity.

Throughout all organic nature there is at work a modifying influence of the kind... as the cause, these specific differences: an influence which, though slow in its action, does, in time, if the circumstances demand it, produce marked changes-an influence, which to all appearance, would produce in the millions of years, and under the great varieties of condition which geological records imply, any amount of change.

The so-called communism of capital, that is, its drive toward an ever more extensive socialization of labor, points ambiguously toward the communism of the multitude.

The discovery of truth is prevented more effectively, not by the false appearance things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice.

It is written, My house shall be called the house of prayer; but ye have made it a den of thieves.

What man can you show me who places any value on his time, who reckons the worth of each day, who understands that he is dying daily?
