Intense, long, certain, speedy, fruitful, pure-Such marks in pleasures and in pains endure.Such pleasures seek if private be thy end:If it be public, wide let them extend.Such pains avoid, whichever be thy view:If pains must come, let them extend to few.

Of corruption, the principal and direct use is, to engage the representatives of the people to betray their trust, and sell themselves and the people to the universal corrupter-the monarch, in his capacity of corrupter-general.

Want keeps pace with dignity. Destitute of the lawful means of supporting his rank, his dignity presents a motive for malversation, and his power furnishes the means.

The community is a fictitious body, composed of the individual persons who are considered as constituting as it were its members. The interest of the community then is what? The sum of the interests of the several members who compose it.

Prose is when all the lines except the last go on to the end. Poetry is when some of them fall short of it.

Judges of elegance and taste consider themselves as benefactors to the human race, whilst they are really only the interrupters of their pleasure ... There is no taste which deserves the epithet good, unless it be the taste for such employments which, to the pleasure actually produced by them, conjoin some contingent or future utility: there is no taste which deserves to be characterized as bad, unless it be a taste for some occupation which has mischievous tendency.

Pleasure is in itself a good; nay, even setting aside immunity from pain, the only good: pain is in itself an evil; and, indeed, without exception, the only evil; or else the words good and evil have no meaning. And this is alike true of every sort of pain, and of every sort of pleasure.

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.

Days of absence,

sad and dreary, 

Clothed in sorrow's dark array,

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

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.

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.

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

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.

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.

Let's go dance under the elms:

Step lively, young lassies.

Let's go dance under the elms:

Gallants, take up your pipes.

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.

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 that time is lost which might be better employed.

Our island is this earth; and the most striking object we behold is the sun. As soon as we pass beyond our immediate surroundings, one or both of these must meet our eye. Thus the philosophy of most savage races is mainly directed to imaginary divisions of the earth or to the divinity of the sun.

The thirst after happiness is never extinguished in the heart of man.

The supreme enjoyment is in satisfaction with oneself ; it is in order to deserve this satisfaction that we are placed on earth and endowed with freedom.

I know my heart, and have studied mankind; I am not made like any one I have been acquainted with, perhaps like no one in existence; if not better, I at least claim originality, and whether Nature did wisely in breaking the mould with which she formed me, can only be determined after having read this work. 

Through the fortunate effect of my frankness, I had the rarest and surest opportunity to know a man well, which is to study him at leisure in his private life and living, so to speak, with himself. For he share himself without reservation and made me feel as much at home in his house as in mine. I had almost no other abode than his own.

Accent is the soul of language; it gives to it both feeling and truth.

As a general rule-never substitute the symbol for the thing signified, unless it is impossible to show the thing itself; for the child's attention is so taken up with the symbol that he will forget what it signifies.

He thinks like a philosopher, but governs like a king.

What good would it be to possess the whole universe if one were its only survivor?

I love liberty, and I loathe constraint, dependence, and all their kindred annoyances. As long as my purse contains money it secures my independence, and exempts me from the trouble of seeking other money, a trouble of which I have always had a perfect horror; and the dread of seeing the end of my independence, makes me proportionately unwilling to part with my money. The money that we possess is the instrument of liberty, that which we lack and strive to obtain is the instrument of slavery.

Much more naturally than you do: because flight is a much more natural consequence of fear than of hate. He doesn't flee men because he hates them, but because he is afraid of them. He doesn't flee them in order to harm them, but to try o escape the harm they wish to do to him. They, on the contrary, don't seek him through friendship, but through hate. They seek him and he flees from them just as in the wilderness of Africa, where there are few men and many tigers, the men flee the tigers, the men flee the tigers, and the tigers seek the men.

An honest man nearly always thinks justly.

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. 

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.

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

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. 

Thoughts without content are empty, intuitions without concepts are blind. The understanding can intuit nothing, the senses can think nothing. Only through their unison can knowledge arise.

Through failures one becomes intelligent; but the one who has trained himself in this subject so that he can make others wise through their own failures, has used his intelligence. Ignorance is not stupidity.

All the interests of my reason, speculative as well as practical, combine in the three following questions: 1. What can I know? 2. What ought I to do? 3. What may I hope?

Good and strong will. Mechanism must precede science (learning). Also in morals and religion? Too much discipline makes one narrow and kills proficiency. Politeness belongs, not to discipline, but to polish, and thus comes last.
