Dialogue never ends not for lack of time or opportunity but for essential reasons.

Aristodemus, a friend of Antigonus, supposed to be a cook's son, advised him to moderate his gifts and expenses. "Thy words," said he, "Aristodemus, smell of the apron."

Invention is the mother of all necessities.

Chaos is rejecting all you have learned. Chaos is being yourself.

We are disposed, somewhat by culture and somewhat by nature, to solve our problems by violence, and even to enjoy doing so. And yet by now all of us must at least have suspected that our right to live, to be free, and to be at peace is not guaranteed by any act of violence. It can be guaranteed only by our willingness that all other persons should live, be free, and be at peace - and by our willingness to use or give our own lives to make that possible.

If any philosopher had been asked for a definition of infinity, he might have produced some unintelligible rigmarole, but he would certainly not have been able to give a definition that had any meaning at all.

To suppose universal laws of nature capable of being apprehended by the mind and yet having no reason for their special forms, but standing inexplicable and irrational, is hardly a justifiable position. Uniformities are precisely the sort of facts that need to be accounted for. That a pitched coin should sometimes turn up heads and sometimes tails calls for no particular explanation; but if it shows heads every time, we wish to know how this result has been brought about. Law is par excellence the thing that wants a reason.

In the most secret chamber of the spirit of him who believes himself convinced that death puts an end to his personal consciousness, his memory, for ever, and all unknown to him perhaps, there lurks a shadow, a vague shadow, a shadow of uncertainty, and while he says within himself, "Well, let us live this life that passes away, for there is no other!" the silence of this secret chamber speaks to him and murmurs, "Who knows!... " These voices are like the humming of a mosquito when the south-west wind roars through the trees in the wood; we cannot distinguish this faint humming, yet nevertheless, merged in the clamor of the storm, it reaches the ear.

The hearing ear is always found close to the speaking tongue.

The new education must consist essentially in this, that it completely destroys freedom of will in the soil which it undertakes to cultivate, and produces on the contrary strict necessity in the decisions of the will, the opposite being impossible. Such a will can henceforth be relied on with confidence and certainty.

Our particular principles of religion are a subject of accountability to our god alone. I enquire after no man's and trouble none with mine; nor is it given to us in this life to know whether yours or mine, our friend's or our foe's, are exactly the right.

Raillery is a mode of speaking in favor of one's wit at the expense of one's better nature.

The pragmatic justification is that liberalism is... a political doctrine that seeks to enable societies to govern themselves over diversity. It arose in the minds of thinkers like Thomas Hobbes or John Locke or Samuel Pufendorf... as a result of the European wars of religion following the Protestant Reformation.

Now, on the contrary, when every one is to cultivate himself into man, condemning a man to machine-like labor amounts to the same thing as slavery. If a factory-worker must tire himself to death twelve hours and more, he is cut off from becoming man. Every labor is to have the intent that the man be satisfied. His labor is nothing taken by itself, has no object in itself, is nothing complete in itself; he labors only into another's hands, and is used (exploited) by this other.

It would be wrong to suppose that the man of any particular period always looks upon past times as below the level of his own, simply because they are past. It is enough to recall that to the seeming of Jorge Manrique, "Any time gone by was better."... From A.D. 150 on, this impression of a shrinking of vitality, of a falling from position, of decay and loss of pulse shows itself increasingly in the Roman Empire. Had not Horace already sung: "Our fathers, viler than our grandfathers, begot us who are even viler, and we shall bring forth a progeny more degenerate still"?

One can learn such a lot and enjoy such a lot in seventy years, and three generations is a long, long time to see human follies and acquire human wisdom. Anyone who is wise and has lived long enough to witness the changes of fashion and morals and politics through the rise and fall of three generations should be perfectly satisfied to rise from his seat and go away saying, "It was a good show," when the curtain falls.

That the human mind has a certain order of possible progress, in which some things must precede others, an order which governments and public instructors can modify to some, but not to an unlimited extent: that all questions of political institutions are relative, not absolute, and that different stages of human progress not only will have, but ought to have, different institutions: That government is always either in the hands, or passing into the hands, of whatever is the strongest power in society, and that what this power is, does not depend on institutions, but institutions on it: That any general theory or philosophy of politics supposes a previous theory of human progress, and that this is the same thing with a philosophy of history.

No, the Great Man does not boast himself sincere, far from that; perhaps does not ask himself if he is so: I would say rather, his sincerity does not depend on himself; he cannot help being sincere! The great Fact of Existence is great to him. Fly as he will, he cannot get out of the awful presence of this Reality. His mind is so made; he is great by that, first of all. Fearful and wonderful, real as Life, real as Death, is this Universe to him. Though all men should forget its truth, and walk in a vain show, he cannot. At all moments the Flame-image glares in upon him; undeniable, there, there!-I wish you to take this as my primary definition of a Great Man. A little man may have this, it is competent to all men that God has made: but a Great Man cannot be without it.

We cannot grasp any idea, any organ of meditation, we cannot possess it in full force, until we have felt and sensed it, as much so as if it were an odor or a color.

Naturally, every age thinks that all ages before it were prejudiced, and today we think this more than ever and are just as wrong as all previous ages that thought so. How often have we not seen the truth condemned! It is sad but unfortunately true that man learns nothing from history.

Morality must be the heart of our existence, if it is to be what it wants to be for us. ... The highest form of philosophy is ethics. Thus all philosophy begins with "I am." The highest statement of cognition must be an expression of that fact which is the means and ground for all cognition, namely, the goal of the I.

Liberty, taking the word in its concrete sense, consists in the ability to choose.

Most Christians are superstitious rather than pious, and except for the name of Christ differ hardly at all from superstitious pagans.

[after quoting from Lucretius] In the face of warfare and inevitable death, there is no wisdom but in ataraxia, "to look on all things with a mind at peace"." Here, clearly, the old pagan joy of life is gone, and an almost exotic spirit touches a broken lyre. History, which is nothing if not humorous, was never so facetious as when she gave to this abstemious and epic pessimist the name of Epicurean.

Why does God afflict the best of men with ill-health, or sorrow, or other troubles? Because in the army the most hazardous services are assigned to the bravest soldiers: a general sends his choicest troops to attack the enemy in a midnight ambuscade, to reconnoitre his line of march, or to drive the hostile garrisons from their strong places. No one of these men says as he begins his march, " The general has dealt hardly with me," but "He has judged well of me."

Even in the games of children there are things to interest the greatest mathematician.

Everyone sits in the prison of his own ideas; he must burst it open, and that in his youth, and so try to test his ideas on reality.

Resignation' is a keynote in Comte's writings, deriving directly from assent to invariable social laws. 'True resignation, that is, a disposition to endure necessary evils steadfastly and without any hope of compensation therefore, can result only from a profound feeling for the invariable laws that govern the variety of natural phenomena.

No circumstance is ever so desperate that one cannot nurture some spark of hope.

I am particularly grateful to Nozick for his unfailing help and encouragement during the last stages.

It is the real, and not the map, whose vestiges persist here and there in the deserts that are no longer those of the Empire, but ours: The desert of the real itself.

Wherever there is great property, there is great inequality.

Wonder is the foundation of all philosophy, research is the means of all learning, and ignorance is the end.

This spirit thrusts itself forward, confident of commendation and esteem. It is superior to all, monarch of all it surveys; hence it should be subservient to nothing, finding no task too heavy, and nothing strong enough to weigh down the shoulders of a man.

But the wise man is fortified against all inroads; he is alert; he will not retreat before the attack of poverty, or of sorrow, or of disgrace, or of pain. He will walk undaunted both against them and among them.

Nostalgia, more than anything, gives us the shudder of our own imperfection.

To be honest, as critical as I am of people for being anti-human, I love everybody so much for sinking on this ship with me. Admit it or not, we're all dying together.

It is Christ Himself, not the Bible, who is the true Word of God. The Bible, read in the right spirit and with the guidance of good teachers, will bring us to Him.

And he arrives at the cogito ergo sum, which St. Augustine had already anticipated... "I think therefore I am," can only mean "I think, therefore I am a thinker"; this being of "I am," which is deduced from "I think," is merely a knowing; this being is a knowledge, but not life. And the primary reality is not that I think, but that I live, for those also live who do not think. Although this living may not be a real living. God! what contradictions when we seek to join in wedlock life and reason!

That most knowing of persons - gossip.

Form no covetous desire, so that the demon of greediness may not deceive thee, and the treasure of the world may not be tasteless to thee.
