As soon as we have contrived to give our pupil an idea of the word "Useful," we have got an additional means of controlling him, for this word makes a great impression on him, provided that its meaning for him is a meaning relative to his own age, and provided he clearly sees its relation to his own well-being. This word makes no impression on your scholars because you have taken no pains to give it a meaning they can understand, and because other people always undertake to supply their needs so that they never require to think for themselves, and do not know what utility is. "What is the use of that?"

What I had to say was so clear and I felt it so deeply that I am amazed by the tediousness, repetitiousness, verbiage, and disorder of this writing. What would have made it lively and vehement coming from another's pen is precisely what has made it dull and slack coming from mine. The subject was myself, and I no longer found on my own interest that zeal and vigor of courage which can exalt a generous soul only for another person's cause.

The offender never forgives.

Remorse sleeps during a prosperous period but wakes up in adversity. 

A country cannot subsist well without liberty, nor liberty without virtue.

Let's not be dazzled by the sententious glitter with which error and lying often cover themselves. Society is not created by the crowd, and bodies come together in vain when hearts reject each other. The truly sociable man is more difficult in his relationships than others; those which consist only in false appearances cannot suit him. He prefers to live far from wicked men without thinking about them, than to see them and hate them. He prefers to flee his enemy rather than seek him out to harm him. A person who knows no other society than that of the heart will not seek his society in your circles. That is How J.J. must have thought and behaved before the conspiracy of which he is the object.

The origin of our passions, the root and spring of all the rest, the only one which is born with man, which never leaves him as long as he lives, is self-love; this passion is primitive, instinctive, it precedes all the rest, which are in a sense only modifications of it. In this sense, if you like, they are all natural. But most of these modifications are the result of external influences, without which they would never occur, and such modifications, far from being advantageous to us, are harmful. They change the original purpose and work against its end; then it is that man finds himself outside nature and at strife with himself.

There as here, passions are the motive of all action, but they are livelier, more ardent, or merely simpler and purer, thereby assuming a totally different character. All the first movements of nature are good and right.

Two conflicting types of educational systems spring from these conflicting aims. One is public and common to many, the other private and domestic. If you wish to know what is meant by public education, read Plato's Republic. Those who merely judge books by their titles take this for a treatise on politics, but it is the finest treatise on education ever written. In popular estimation the Platonic Institute stands for all that is fanciful and unreal. For my own part I should have thought the system of Lycurgus far more impracticable had he merely committed it to writing. Plato only sought to purge man's heart; Lycurgus turned it from its natural course. The public institute does not and cannot exist, for there is neither country nor patriot. The very words should be struck out of our language. The reason does not concern us at present, so that though I know it I refrain from stating it.

It is too difficult to think nobly when one thinks only of earning a living. 

Days of absence,

sad and dreary, 

Clothed in sorrow's dark array,

Days of absence, I am weary: She I love is far away.

Oh providence! Oh nature! Treasure of the poor, resource of the unfortunate. The person who feels, knows your holy laws and trusts them, the person whose heart is at peace and whose body does not suffer, thanks to you is not entirely prey to adversity.

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.

Beings who are so uniquely constituted must necessarily express themselves in other ways than ordinary men. It is impossible that with souls so differently modified, they should not carry over into the expression of their feelings and ideas the stamp of those modifications.

Let us not forget what befits our present state in the pursuit of vain fancies. Mankind has its place in the sequence of things; childhood has its place in the sequence of human life; the man must be treated as a man and the child as a child. Give each his place, and keep him there. Control human passions according to man's nature; that is all we can do for his welfare. The rest depends on external forces, which are beyond our control.

Hatred, as well as love, renders its votaries credulous.

Virtue is a state of war, and to live in it means one always has some battle to wage against oneself.

Visions are a feeble resource, you will say, against great adversity! Oh Sir, these visions may possibly have more reality than all those apparent goods about which men make so much ado, for they never bring a true feeling of happiness to the soul, and those who possess them are equally forced to project themselves into the future for want of finding enjoyments that satisfy them, in the present.

It is a mistake to classify the passions as lawful and unlawful, so as to yield to the one and refuse the other. All alike are good if we are their masters; all alike are bad if we abandon ourselves to them. Nature forbids us to extend our relations beyond the limits of our strength; reason forbids us to want what we cannot get, conscience forbids us, not to be tempted, but to yield to temptation. To feel or not to feel a passion is beyond our control, but we can control ourselves. Every sentiment under our own control is lawful; those which control us are criminal. A man is not guilty if he loves his neighbour's wife, provided he keeps this unhappy passion under the control of the law of duty; he is guilty if he loves his own wife so greatly as to sacrifice everything to that love.

Let's go dance under the elms:

Step lively, young lassies.

Let's go dance under the elms:

Gallants, take up your pipes.

As for the Soothsayer, although I am certain no one feels the true beauties of that work better than I, I am far from finding these beauties in the same places as the infatuated public does. They are not the products of study and knowledge, but rather are inspired by taste and sensitivity.

There is only one man who gets his own way-he who can get it single-handed; therefore freedom, not power, is the greatest good. That man is truly free who desires what he is able to perform, and does what he desires. This is my fundamental maxim. Apply it to childhood, and all the rules of education spring from it. Society has enfeebled man, not merely by robbing him of the right to his own strength, but still more by making his strength insufficient for his needs. This is why his desires increase in proportion to his weakness; and this is why the child is weaker than the man. If a man is strong and a child is weak it is not because the strength of the one is absolutely greater than the strength of the other, but because the one can naturally provide for himself and the other cannot. Thus the man will have more desires and the child more caprices, a word which means, I take it, desires which are not true needs, desires which can only be satisfied with the help of others.

I remembered the way out suggested by a great princess when told that the peasants had no bread: "Well, let them eat cake".

I shall need only myself to be happy.

I have entered on an enterprise which is without precedent, and will have no imitator. I propose to show my fellows a man as nature made him, and this man shall be myself.

All that time is lost which might be better employed.

I want you to read the true system of the heart, drafted by a decent man and published under another name. I do not want you to be biased against good and useful books merely because a man unworthy of reading them has the audacity to call himself the Author.

All human knowledge begins with intuitions, proceeds from thence to concepts, and ends with ideas.

England and France, the two most civilized nations on earth, who are in contrast to each other because of their different characters, are, perhaps chiefly for that reason, in constant feud with one another. Also, England and France, because of their inborn characters, of which the acquired and artificial character is only the result, are probably the only nations who can be assumed to have a particular and, as long as both national characters are not blended by the force of war, unalterable characteristics. That French has become the universal language of conversation, especially in the feminine world, and that English is the most widely used language of commerce among tradesmen, probably reflects the difference in their continental and insular geographic situation.

All true metaphysics is taken from the essential nature of the thinking faculty itself, and therefore in nowise invented, since it is not borrowed from experience, but contains the pure operations of thought, that is, conceptions and principles à priori, which the manifold of empirical presentations first of all brings into legitimate connection, by which it can become empirical knowledge, i.e. experience. ...mathematical physicists were thus quite unable to dispense with such metaphysical principles...

The universal and lasting establishment of peace constitutes not merely a part, but the whole final purpose and end of the science of right as viewed within the limits of reason.

Man has his own inclinations and a natural will which, in his actions, by means of his free choice, he follows and directs. There can be nothing more dreadful than that the actions of one man should be subject to the will of another; hence no abhorrence can be more natural than that which a man has for slavery. And it is for this reason that a child cries and becomes embittered when he must do what others wish, when no one has taken the trouble to make it agreeable to him. He wants to be a man soon, so that he can do as he himself likes.

All our knowledge falls with the bounds of experience.

Money is the password, and all doors, which are closed to the man of lesser means, fly open to those whom Plutus favors. The invention of money, which has no other usefulness (or at least it should not have any) except for the commercial exchange of the products of man's industry, now serves all that is physically good among men. Especially after money was represented by metal, it has produced avarice which, finally, without indulgence, but by its mere possession, and even with the resolution (of the stingy) not to spend it, still contains a power which people believe can sufficiently compensate for the lack of any other power.

Morality is not properly the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.

The more one presupposes that his own power will suffice him to realize what he desires the more practical is that desire. When I treat a man contemptuously, I can inspire him with no practical desire to appreciate my grounds of truth. When I treat any one as worthless, I can inspire him with no desire to do right.

Criticism alone can sever the root of materialism, fatalism, atheism, free-thinking, fanaticism, and superstition, which can be injurious universally; as well as of idealism and skepticism, which are dangerous chiefly to the Schools, and hardly allow of being handed on to the public.

To require that a so-called layman should not use his own reason in religious matters, particularly since religion is to be appreciated as moral, but instead follow the appointed clergyman and thus someone else's reason, is an unjust demand because as to morals every man must account for all his doings. The clergyman will not and even cannot assume such a responsibility.

Philosophical knowledge is the knowledge gained by reason from concepts; mathematical knowledge is the knowledge gained by reason from the construction of concepts.

The first characteristic of the human species is man's ability, as a rational being, to establish character for himself, as well as for the society into which nature has placed him. This ability, however, presupposes an already favorable natural predisposition and an inclination to the good in man, because the evil is really without character (since it is at odds with itself, and since it does not tolerate any lasting principle within itself)

Natural science is throughout either a pure or an applied doctrine of motion.

Even if a civil society were to be dissolved by the consent of all its members (e.g., if a people inhabiting an island decided to separate and disperse throughout the world), the last murderer remaining in prison would first have to be executed, so that each has done to him what his deeds deserve and blood guilt does not cling to the people for not having insisted upon this punishment; for otherwise the people can be regarded as collaborators in his public violation of justice.

Suicide evokes revulsion with horror, because everything in nature seeks to preserve itself: a damaged tree, a living body, an animal; and in man, then, is freedom, which is the highest degree of life, and constitutes the worth of it, to become now a principium for self-destruction? This is the most horrifying thing imaginable. For anyone who has already got so far as to be master, at any time, over his own life, is also master over the life of anyone else; for him, the door stands open to every crime, and before he can be seized he is ready to spirit himself away out of the world. So suicide evokes horror, in that a man thereby puts himself below the beasts. We regard a suicide as a carcase, whereas we feel pity for one who meets his end through fate.

It is therefore correct to say that the senses do not err - not because they always judge rightly, but because they do not judge at all.

This species works intentionally on its own destruction (by war). This, however, does not keep the rational creatures of such a constantly advancing culture, even in the midst of war, from promising to mankind in coming centuries an unequivocal prospect of bliss which will never end.

it is absurd ... to hope that maybe another Newton may some day arise, to make intelligible to us even the genesis of but a blade of grass

The evil effect of science upon men is principally this, that by far the greatest number of those who wish to display a knowledge of it accomplish no improvement at all of the understanding, but only a perversity of it, not to mention that it serves most of them as a tool of vanity.

The light dove, cleaving the air in her free flight, and feeling its resistance, might imagine that its flight would be still easier in empty space.

The guidelines for achieving wisdom consist of three leading maxims: 1) Think for yourself; 2) (in communication with other people) Put yourself in the place of the other person; 3) Always think by remaining faithful to your own self.

It is precisely in knowing its limits that philosophy consists.
