Art is a human activity consisting in this, that one consciously, by means of certain external symbols, conveys to others the feelings one has experienced, whereby people so infected by these feelings, also experience them.

During and after World War II, a large number of academic economists were exposed directly to business life, and had more or less extensive opportunities to observe how decisions were actually made in business organizations. Moreover, those who became active in the development of the new management science were faced with the necessity of developing decision-making procedures that could actually be applied in practical situations. Surely these trends would be conducive to moving the basic assumptions of economic rationality in the direction of greater realism.

Even if the whole world were to fall to pieces, the unity of the psyche would never be shattered. And the wider and more numerous the fissures on the surface, the more the unity is strengthened in the depths.

These five rules [above] form all that is necessary to render proofs convincing, immutable, and to say all, geometrical; and the eight rules together render them even more perfect.

Several times I asked myself, "Can it be that I have overlooked something, that there is something which I have failed to understand? Is it not possible that this state of despair is common to everyone?" And I searched for an answer to my questions in every area of knowledge acquired by man. For a long time I carried on my painstaking search; I did not search casually, out of mere curiosity, but painfully, persistently, day and night, like a dying man seeking salvation. I found nothing.

Just as the witticism brings two very different real objects under one concept, the pun brings two different concepts, by the assistance of accident, under one word.

How many women thus waste life away the prey of discontent, who might have practised as physicians, regulated a farm, managed a shop, and stood erect, supported by their own industry, instead of hanging their heads surcharged with the dew of sensibility, that consumes the beauty to which it at first gave lustre.

With the disintegration of all that Nietzsche had revered, existence, to him, had become a desert in which only one thing remained, namely that which had relentlessly forced him into this path: truthfulness that knows no limits and is not subject to any condition.

Whoever imposes severe punishment becomes repulsive to the people; while he who awards mild punishment becomes contemptible. But whoever imposes punishment as deserved becomes respectable. For punishment when awarded with due consideration, makes the people devoted to righteousness and to works productive of wealth and enjoyment; while punishment, when ill-awarded under the influence of greed and anger or owing to ignorance, excites fury even among hermits and ascetics dwelling in forests, not to speak of householders.

Nature has made a race of workers; that is the Chinese race, with a marvelous dexterity of hand and hardly any feeling of honor; govern this race with justice by exacting from them through the competence of such government an ample dowry to the conquering race; the subordinate race will be satisfied; a race of workers of the earth, such is the Negro; let us be for him good and human, and everything will be in order -- a race of masters and soldiers, that is the European race.

The imagination loves to trifle with what is not.

Suppose a surface to be part red and part blue; so that every point on it is either red or blue, and of course, no part can be both red and blue. What then, is the color of the surface in the immediate neighborhood of the point. ...it follows that the boundary is half red and half blue. In like manner, we find it necessary to hold that consciousness essentially occupies time... Thus, the present is half past and half time to come. ...Take another case: the velocity of a particle at any instant of time is its mean velocity during an infinitesimal instant in which that time is consumed. Just so, my immediate feeling is my feeling through an infinitesimal duration containing the present instant.

The most dangerous madmen are those created by religion, and ... people whose aim is to disrupt society always know how to make good use of them on occasion.

And the conversion of the other Don Quixote - he who was converted only to die - was possible because he was mad, and it was his madness, and not his death or his conversion that immortalized him, earning him forgiveness for this crime of having been born. Felix culpa! And neither was his madness cured, but only transformed. His death was his last knightly adventure; in dying he stormed heaven, which suffereth violence.

Cultivators of the earth are the most valuable citizens. They are the most vigorous, the most independent, the most virtuous, and they are tied to their country and wedded to its liberty and interests by the most lasting bands. As long therefore as they can find employment in this line, I would not convert them into mariners, artisans, or any thing else. But our citizens will find employment in this line till their numbers, and of course their productions, become too great for the demand both internal and foreign.

Of all those expensive and uncertain projects, however, which bring bankruptcy upon the greater part of the people who engage in in them, there is none perhaps more perfectly ruinous than the search after new silver and gold mines. It is perhaps the most disadvantageous lottery in the world, or the one in which the gain of those who draw the prizes bears the least proportion to the loss of those who draw the blanks: for though the prizes are few and the blanks are many, the common price of a ticket is the whole fortune of a very rich man.

Whenever government assumes to deliver us from the trouble of thinking for ourselves, the only consequences it produces are those of torpor and imbecility.

When the apostle James was talking about faith and works against those who thought their faith was enough, and didn't want to have good works, he said, You believe God is one; you do well; the demons also believe, and tremble.

It is an advantage to all narrow wisdom and narrow morals that their maxims have a plausible air; and, on a cursory view, appear equal to first principles. They are light and portable. They are as current as copper coin; and about as valuable. They serve equally the first capacities and the lowest; and they are, at least, as useful to the worst men as to the best. Of this stamp is the cant of not man, but measures; a sort of charm by which many people get loose from every honourable engagement.

The universe is what it is, not what I choose that it should be.

The greatness of America lies not in being more enlightened than any other nation, but rather in her ability to repair her faults.

And you can also commit injustice by doing nothing.

The aim of jazz is the mechanical reproduction of a regressive moment, a castration symbolism. 'Give up your masculinity, let yourself be castrated,' the eunuchlike sound of the jazz band both mocks and proclaims, 'and you will be rewarded, accepted into a fraternity which shares the mystery of impotence with you, a mystery revealed at the moment of the initiation rite.

Let others complain that the age is wicked; my complaint is that it is paltry; for it lacks passion. Men's thoughts are thin and flimsy like lace, they are themselves pitiable like the lacemakers. The thoughts of their hearts are too paltry to be sinful. For a worm it might be regarded as a sin to harbor such thoughts, but not for a being made in the image of God. Their lusts are dull and sluggish, their passions sleepy. They do their duty, these shopkeeping souls, but they clip the coin a trifle, like the Jews; they think that even if the Lord keeps ever so careful a set of books, they may still cheat Him a little. Out upon them! This is the reason my soul always turns back to the Old Testament and to Shakespeare. I feel that those who speak there are at least human beings; they hate, they love, they murder their enemies, and curse their descendants throughout all generations, they sin.

Indeed, I think we may concede to our Academician, without flattery, his claim that in the principle [principio, i. e., accelerated motion] laid down in this treatise he has established a new science dealing with a very old subject. Observing with what ease and clearness he deduces from a single principle the proofs of so many theorems, I wonder not a little how such a question escaped the attention of Archimedes, Apollonius, Euclid and so many other mathematicians and illustrious philosophers, especially since so many ponderous tomes have been devoted to the subject of motion.

All human activity is prompted by desire. There is a wholly fallacious theory advanced by some earnest moralists to the effect that it is possible to resist desire in the interests of duty and moral principle. I say this is fallacious, not because no man ever acts from a sense of duty, but because duty has no hold on him unless he desires to be dutiful. If you wish to know what men will do, you must know not only, or principally, their material circumstances, but rather the whole system of their desires with their relative strengths.

Those who have taken the planets to be inanimate bodies without function, limited to traveling geometric paths, resemble idiots who would believe that the brain is inanimate because it has no visible function, or that the stomach is idle because it does no visible work as do our limbs. Civilizees have always been reproached for believing nature to be limited to known effects. If the planets were not animate creatures endowed with functions, God would then appear to be an advocate of laziness. He would have created universes furnished with large inert bodies spending eternity in purposeless meandering as do the idlers in our society.

It belongs to the imperfection of everything human that man can only attain his desire by passing through its opposite.

If you believe what you like in the gospels, and reject what you don't like, it is not the gospel you believe, but yourself.

To conceive the good, in fact, is not sufficient; it must be made to succeed among men. To accomplish this less pure paths must be followed.

The use of the intellect in the sciences whose primitive concepts as well as axioms are given by sensuous intuition is only logical, that is, by it we only subordinate cognitions to one another according to their relative universality conformably to the principle of contradiction, phenomena to more general phenomena, and consequences of pure intuition to intuitive axioms. But in pure philosophy, such as metaphysics, in which the use of the intellect in respect to principles is real, that is to say, where the primary concept of things and relations and the very axioms are given originally by the pure intellect itself, and not being intuitions do not enjoy immunity from error, the method precedes the whole science, and whatever is attempted before its precepts are thoroughly discussed and firmly established is looked upon as rashly conceived and to be rejected among vain instances of mental playfulness.

I believe with Schopenhauer: We can do what we wish, but we can only wish what we must. Practically, I am, nevertheless, compelled to act as if freedom of the will existed. If I wish to live in a civilized community, I must act as if man is a responsible being. I know that philosophically a murderer is not responsible for his crime; nevertheless, I must protect myself from unpleasant contacts. I may consider him guiltless, but I prefer not to take tea with him.

Crime in full glory consolidates authority by the sacred fear it inspires.

Even those who have renounced Christianity and attack it, in their inmost being still follow the Christian ideal, for hitherto neither their subtlety nor the ardor of their hearts has been able to create a higher ideal of man and of virtue than the ideal given by Christ.

Genet is a man-failure: he wills the impossible in order to derive from the tragic grandeur of this defeat the assurance that there is something other than the possible.

Man can hardly even recognize the devils of his own creation.

O tenderly the haughty day Fills his blue urn with fire; One morn is in the mighty heaven, And one in our desire.

Renaissance Italy became a kind of Hollywood collection of sets of antiquity, and the new visual antiquarianism of the Renaissance provided an avenue to power for men of any class.

A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another.

The huge laugh is a most extreme expression of freedom.

One man prays thus: How shall I be able to lie with that woman? Do thou pray thus: How shall I not desire to lie with her? Another prays: How shall I be released from this? Another prays: How shall I not desire to be released? Another thus: How shall I not lose my little son? Thou thus: How shall I not be afraid to lose him? In fine, turn thy prayers this way, and see what comes.

Order thyself so, that thy Soul may always be in good estate; whatsoever become of thy body.

Of all forms of caution, caution in love is perhaps the most fatal to true happiness.

It seems to me, that if the matter of our sun and planets and all the matter of the universe, were evenly scattered throughout all the heavens, and every particle had an innate gravity towards all the rest, and the whole of space throughout which this matter was scattered was but finite, the matter on [toward] the outside of this space would, by its gravity, tend towards all the matter on the inside, and, by consequence, fall down into the middle of the whole space, and there compose one great spherical mass. But if the matter was evenly disposed throughout an infinite space it could never convene into one mass; but some of it would convene into one mass and some into another, so as to make an infinite number of great masses, scattered at great distances from one another throughout all that infinite space.
