Complete ignorance with regard to certain matters is perhaps the best thing for children; but let them learn very early what it is impossible to conceal from them permanently. Either their curiosity must never be aroused, or it must be satisfied before the age when it becomes a source of danger. Your conduct towards your pupil in this respect depends greatly on his individual circumstances, the society in which he moves, the position in which he may find himself, etc. Nothing must be left to chance; and if you are not sure of keeping him in ignorance of the difference between the sexes till he is sixteen, take care you teach him before he is ten.

I regard utility as the ultimate appeal on all ethical questions; but it must be utility in the largest sense, grounded on the permanent interests of man as a progressive being.

If thou art pained by any external thing, it is not this that disturbs thee, but thy own judgment about it. And it is in thy power to wipe out this judgment now.

When reason rules, money is a blessing.

For in every country of the world, I believe, the avarice and injustice of princes and sovereign states, abusing the confidence of their subjects, have by degrees diminished the real quantity of metal, which had been originally contained in their coins.

No tears are shed, when an enemy dies.

No sound ought to be heard in the church but the healing voice of Christian charity.

A definition may be very exact, and yet go but a very little way towards informing us of the nature of the thing defined.

A scholar who loves comfort is not worthy of the name.

The fleshless diet contributes to health and to a suitable endurance of hard work in philosophy.

The world evades us because it becomes itself again. That stage scenery masked by habit becomes what it is. It withdraws at a distance from us.

All things are interwoven with one another; a sacred bond unites them; there is scarcely one thing that is isolated from another. Everything is coordinated, everything works together in giving form to one universe. The world-order is a unity made up of multiplicity: God is one, pervading all things; all being is one, all law is one (namely, the common reason which all thinking persons possess) and all truth is one- if, as we believe, there can be but one path to perfection for beings that are alike in kind and reason.

Certainly He says this for me, for thee, for this other man, since He bears His body, the Church. Unless you imagine, brethren, that when He said: My Father, if it be possible, let this cup pass away from (Matt. 26:39), it was the Lord that feared to die. . . . But Paul longed to die, that he might be with Christ. What? The Apostle desires to die, and Christ Himself should fear death? What can this mean, except that He bore our infirmity in Himself, and uttered these words for those who are in His body and still fear death? It is from these that the voice came; it was the voice of His members, not of the Head. When He said, My soul is sorrowful unto death (Matt. 26:38), He manifested Himself in thee, and thee in Himself. And when He said, My God, my God, why has Thou forsaken Me? (Matt. 27:46), the words He uttered on the cross were not His own, but ours.

The foremost, or indeed the sole condition which is required in order to succeed in centralizing the supreme power in a democratic community, is to love equality, or to get men to believe you love it. Thus the science of despotism, which was once so complex, is simplified, and reduced as it were to a single principle.

Kant was also quite aware that "the urgent need" of reason is both different from and "more than mere quest and desire for knowledge." Hence, the distinguishing of the two faculties, reason and intellect, coincides with a distinction between two altogether different mental activities, thinking and knowing.

I hate tyranny, at least I think I do; but I hate it most of all where most are concerned in it. The tyranny of a multitude is a multiplied tyranny. If, as society is constituted in these large countries of France and England, full of unequal property, I must make my choice (which God avert!) between the despotism of a single person, or of the many, my election is made. As much injustice and tyranny has been practised in a few months by a French democracy, as in all the arbitrary monarchies in Europe in the forty years of my observation.

I think he once told us his first short clothes were a hull made mostly or wholly of leather. We all only laughed, for it is now long ago. Thou dear father! Through what stern obstructions was thy way to manhood to be forced, and for us and for our travelling to be made smooth!

Even to-day, in spite of some signs which are making a tiny breach in that sturdy faith, even to-day, there are few men who doubt that motorcars will in five years' time be more comfortable and cheaper than to-day. They believe in this as they believe that the sun will rise in the morning. The metaphor is an exact one. For, in fact, the common man, finding himself in a world so excellent, technically and socially, believes that it has been produced by nature, and never thinks of the personal efforts of highly-endowed individuals which the creation of this new world presupposed. Still less will he admit the notion that all these facilities still require the support of certain difficult human virtues, the least failure of which would cause the rapid disappearance of the whole magnificent edifice.... These traits together make up the well-known psychology of the spoilt child. Chap.

Everything which distinguishes man from the animals depends upon this ability to volatilize perceptual metaphors in a schema, and thus to dissolve an image into a concept. For something is possible in the realm of these schemata which could never be achieved with the vivid first impressions: the construction of a pyramidal order according to castes and degrees, the creation of a new world of laws, privileges, subordinations, and clearly marked boundaries, a new world, one which now confronts that other vivid world of first impressions as more solid, more universal, better known, and more human than the immediately perceived world, and thus as the regulative and imperative world.

He needs no library, for he has not done thinking; no church, for he is himself a prophet; no statute book, for he hath the Lawgiver; no money, for he is value itself; no road, for he is at home where he is.

I would rather be a poor man in a garret with plenty of books than a king who did not love reading.

Truly to escape Hegel involves an exact appreciation of the price we have to pay to detach ourselves from him. It assumes that we are aware of the extent to which Hegel, insidiously perhaps, is close to us; it implies a knowledge, in that which permits us to think against Hegel, of that which remains Hegelian. We have to determine the extent to which our anti-Hegelianism is possibly one of his tricks directed against us, at the end of which he stands, motionless, waiting for us.

To his dog, every man is Napoleon; hence the constant popularity of dogs.

To be like the rock that the waves keep crashing over. It stands unmoved and the raging of the sea falls still around it.

Woes and wonders of power, that tonic hell, synthesis of poison and panacea.

Be gentle with them, Timothy. They want to be free, but they don't know how. Teach them. Reassure them.

Patriotism, when it wants to make itself felt in the domain of learning, is a dirty fellow who should be thrown out of doors.

To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it. Then give up deceiving people; confess ignorance of what you don't know, and leave everyone to form his own articles of faith for himself. Perhaps they won't turn out so bad, especially as they'll rub one another's corners down, and mutually rectify mistakes. The existence of many views will at any rate lay a foundation of tolerance. Those who possess knowledge and capacity may betake themselves to the study of philosophy, or even in their own persons carry the history of philosophy a step further.

But if the labourers could live on air they could not be bought at any price.

As an eminent pioneer in the realm of high frequency currents... I congratulate you on the great successes of your life's work.

But, in my state of mind, this appearance of superiority to illusion added to the effect which Bentham's doctrines produced on me, by heightening the impression of mental power, and the vista of improvement which he did open was sufficiently large and brilliant to light up my life, as well as to give a definite shape to my aspirations.

Physiologically, man in the normal use of technology (or his variously extended body) is perpetually modified by it and in turn finds ever new ways of modifying his technology. Man becomes, as it were, the sex organs of the machine world, as the bee of the plant world, enabling it to fecundate and to evolve ever new forms. The machine world reciprocates man's love by expediting his wishes and desires, namely, in providing him with wealth. One of the merits of motivation research has been the revelation of man's sex relation to the motorcar.

Criminals together. We're in hell, my little friend, and there's never any mistake there. People are not damned for nothing. 

We will likely also find that the nature of the problem to be solved will be a principal determinant of the mix. With our growing understanding of the organization of judgmental and intuitive processes, of the specific knowledge that of the specific knowledge that is required to perform particular judgmental tasks, and of the cues that evoke such knowledge in situations in which it is relevant, we have a powerful new tool for improving expert judgment. We can specify the knowledge and the recognition capabilities that experts in a domain need to acquire, and use these specifications for designing appropriate learning procedures.

To rule the imperial population, behold our vocation.

The wine is bottled poetry.

Compared to the refined culture of sclerotic forms and frames, which mask everything, the lyrical mode is utterly barbarian in its expression. Its value resides precisely in its savage quality: it is only blood, sincerity, and fire.

His imperial muse tosses the creation like a bauble from hand to hand to embody any capricious thought that is uppermost in her mind. The remotest spaces of nature are visited, and the farthest sundered things are brought together by a subtle spiritual connection.

The physicist who states a law of nature with the aid of a mathematical formula is abstracting a real feature of a real material world, even if he has to speak of numbers, vectors, tensors, state-functions, or whatever to make the abstraction.

We are not ostriches, and cannot believe that if we refuse to look at what we do not wish to see, it will not exist. This is especially the case when what we do not wish to see is what we wish to eat. If it were really indispensable, or, if not indispensable, at least in some way useful! But it is quite unnecessary ... And this is continually being confirmed by the fact that young, kind, undepraved people - especially women and girls - without knowing how it logically follows, feel that virtue is incompatible with beefsteaks, and, as soon as they wish to be good, give up eating flesh.

In ordinary visual perception, we see by means of light; we distinguish by means of reflected and refracted colors. But in ordinary perception, this medium of color is mixed, adulterated. While we see, we also hear; we feel pressures, and heat and cold. In a painting, color renders the scene without these alloys and impurities. They are part of the dross that is squeezed out and left behind in an act of intensified expression. The medium becomes color alone, and since color alone must now carry the qualities of movement, touch, sound, etc., that are present physically on their own account in ordinary vision, the expressiveness and energy of color are enhanced.

What a strange machine man is! You fill him with bread, wine, fish, and radishes, and out comes sighs, laughter, and dreams.

With all great deceivers there is a noteworthy occurrence to which they owe their power. In the actual act of deception... they are overcome by belief in themselves. It is this which then speaks so miraculously and compellingly to those who surround them.

That is a long word: forever!

The three great American vices seem to be efficiency, punctuality, and the desire for achievement and success. They are the things that make the Americans so unhappy and so nervous.
