I am convinced that we have a degree of delight, and that no small one, in the real misfortunes and pains of others.

There is, however, a limit at which forbearance ceases to be a virtue.

We scarce ever had a prince, who by fraud, or violence, had not made some infringement on the constitution. We scarce ever had a parliament which knew, when it attempted to set limits to the royal authority, how to set limits to its own. Evils we have had continually calling for reformation, and reformations more grievous than any evils. Our boasted liberty sometimes trodden down, sometimes giddily set up, and ever precariously fluctuating and unsettled; it has only been kept alive by the blasts of continual feuds, wars, and conspiracies.

The zealous never fail to draw political inferences from religious tenets, by which they interest the magistrate in the dispute; and then to the heat of a religious fervour is added the fury of a party zeal. All intercourse is cut off between the parties. They lose all knowledge of each other, tho' countrymen and neighbours, and are therefore easily imposed upon with the most absurd stories concerning each other's opinions and practices. They judge of the hatred of the adverse side by their own. Then fear is added to their hatred; and preventive injuries arise from their fear. The remembrance of the past, the dread of the future, the present ill, will join together to urge them forward to the most violent courses.Such is the manner of proceeding of religious parties towards each other.

In the interval between his campaigns Agricola was employed in the great labours of peace. He knew that the general must be perfected by the legislator; and that the conquest is neither permanent nor honourable, which is only an introduction to tyranny... In short, he subdued the Britons by civilizing them; and made them exchange a savage liberty for a polite and easy subjection. His conduct is the most perfect model for those employed in the unhappy, but sometimes necessary, task of subduing a rude and free people.

No passion so effectually robs the mind of all its powers of acting and reasoning as fear.

It is a general popular error to suppose the loudest complainers for the publick to be the most anxious for its welfare.

The most obvious division of society is into rich and poor; and it is no less obvious, that the number of the former bear a great disproportion to those of the latter. The whole business of the poor is to administer to the idleness, folly, and luxury of the rich; and that of the rich, in return, is to find the best methods of confirming the slavery and increasing the burdens of the poor. In a state of nature, it is an invariable law, that a man's acquisitions are in proportion to his labours. In a state of artificial society, it is a law as constant and as invariable, that those who labour most enjoy the fewest things; and that those who labour not at all have the greatest number of enjoyments. A constitution of things this, strange and ridiculous beyond expression! We scarce believe a thing when we are told it, which we actually see before our eyes every day without being in the least surprised.

In all persuasions the bigots are persecutors; the men of a cool and reasonable piety are favourers of toleration; because the former sort of men not taking the pains to be acquainted with the grounds of their adversaries tenets, conceive them to be so absurd and monstrous, that no man of sense can give into them in good earnest. For which reason they are convinced that some oblique bad motive induces them to pretend to the belief of such doctrines, and to the maintaining of them with obstinacy. This is a very general principle in all religious differences, and it is the corner stone of all persecution.

These principles it is necessary strictly to attend to, because they will serve much to explain the whole course both of government and real property, wherever the German nations obtained a settlement; the whole of their government depending for the most part upon two principles in our nature,-ambition, that makes one man desirous, at any hazard or expense, of taking the lead amongst others; and admiration, which makes others equally desirous of following him from the mere pleasure of admiration, and a sort of secondary ambition, one of the most universal passions among men. These two principles, strong both of them in our nature, create a voluntary inequality and dependence.

When any work seems to have required immense force and labor to affect it, the idea is grand. Stonehenge, neither for disposition nor ornament, has anything admirable; but those huge rude masses of stone, set on end, and piled each on other, turn the mind on the immense force necessary for such a work. Nay, the rudeness of the work increases this cause of grandeur, as it excludes the idea of art and contrivance; for dexterity produces another sort of effect, which is different enough from this.

The Crown of Great Britain cannot, in my opinion, be too magnificent. Let us see some great public works set on foot; let it never be said, that the Commons of Great Britain failed in what they owe to the first Crown in the world. Looking up to royalty, I do say, it is the oldest and one of the best parts of our constitution. I wish it should look like royalty; that it should look like a King; like a King of Great Britain.

The rich in all societies may be thrown into two classes. The first is of those who are powerful as well as rich, and conduct the operations of the vast political machine. The other is of those who employ their riches wholly in the acquisition of pleasure. As to the first sort, their continual care and anxiety, their toilsome days and sleepless nights, are next to proverbial. These circumstances are sufficient almost to level their condition to that of the unhappy majority; but there are other circumstances which place them in a far lower condition. Not only their understandings labour continually, which is the severest labour, but their hearts are torn by the worst, most troublesome, and insatiable of all passions, by avarice, by ambition, by fear and jealousy. No part of the mind has rest. Power gradually extirpates from the mind every humane and gentle virtue. Pity, benevolence, friendship, are things almost unknown in high stations.

Laws, like houses, lean on one another.

The writers against religion, whilst they oppose every system, are wisely careful never to set up any of their own.

A great profusion of things, which are splendid or valuable in themselves, is magnificent. The starry heaven, though it occurs so very frequently to our view, never fails to excite an idea of grandeur. This cannot be owing to the stars themselves, separately considered. The number is certainly the cause. The apparent disorder augments the grandeur, for the appearance of care is highly contrary to our idea of magnificence. Besides, the stars lie in such apparent confusion, as makes it impossible on ordinary occasions to reckon them. This gives them the advantage of a sort of infinity.

There is only one passion, the passion for happiness.

The world is the house of the strong. I shall not know until the end what I have lost or won in this place, in this vast gambling den where I have spent more than sixty years, dicebox in hand, shaking the dice.

The first promise exchanged by two beings of flesh was at the foot of a rock that was crumbling into dust; they took as witness for their constancy a sky that is not the same for a single instant; everything changed in them and around them, and they believed their hearts free of vicissitudes. O children! always children!

Gaiety - a quality of ordinary men. Genius always presupposes some disorder in the machine.

Good music is very close to primitive language.

The infant runs toward it with its eyes closed, the adult is stationary, the old man approaches it with his back turned.

It is said that desire is a product of the will, but the converse is in fact true: will is a product of desire.

When one compares the talents one has with those of a Leibniz, one is tempted to throw away one's books and go die quietly in the dark of some forgotten corner.

Scepticism is the first step towards truth. Variant: A thing is not proved just because no one has ever questioned it. What has never been gone into impartially has never been properly gone into. Hence skepticism is the first step toward truth. It must be applied generally, because it is the touchstone.

Do you see this egg? With this you can topple every theological theory, every church or temple in the world. What is it, this egg, before the seed is introduced into it? An insentient mass. And after the seed has been introduced to into it? What is it then? An insentient mass. For what is the seed itself other than a crude and inanimate fluid? How is this mass to make a transition to a different structure, to sentience, to life? Through heat. And what will produce that heat in it? Motion. "Conversation Between D'Alembert and Diderot", as quoted in Selected Writings (1966) edited by Lester G. Crocker, and The Enlightenment and the Intellectual Foundations of Modern Culture (2004) by Louis K Dupré, p. 30 Variant translation: See this egg. It is with this that all the schools of theology and all the temples of the earth are to be overturned.

Pithy sentences are like sharp nails which force truth upon our memory.

In order to shake a hypothesis, it is sometimes not necessary to do anything more than push it as far as it will go.

Jacques said that his master said that everything good or evil we encounter here below was written on high.

To attempt the destruction of our passions is the height of folly. What a noble aim is that of the zealot who tortures himself like a madman in order to desire nothing, love nothing, feel nothing, and who, if he succeeded, would end up a complete monster!

Gratitude is a burden, and every burden is made to be shaken off.

Man was born to live with his fellow human beings. Separate him, isolate him, his character will go bad, a thousand ridiculous affects will invade his heart, extravagant thoughts will germinate in his brain, like thorns in an uncultivated land.

The good of the people must be the great purpose of government. By the laws of nature and of reason, the governors are invested with power to that end. And the greatest good of the people is liberty. It is to the state what health is to the individual.

The possibility of divorce renders both marriage partners stricter in their observance of the duties they owe to each other. Divorces help to improve morals and to increase the population.

I am beginning to feel that I am growing old; soon, I shall have to eat mush like children. I shall no longer be able to speak, which will be a rather great advantage for others and but a small inconvenience for myself.... The time in which I count in years is gone; that in which I count in days is here.... I had thought that the fibers of the heart would grow callous with age, it's not at all the case. I am not sure that my sensitivity hasn't increased; everything moves me, affects me.... To fade out between a man feeling your pulse and another bothering your head; not to know where one comes from, why one came, where one is going ...

Shakespeare's fault is not the greatest into which a poet may fall. It merely indicates a deficiency of taste.

Only a very bad theologian would confuse the certainty that follows revelation with the truths that are revealed. They are entirely different things.

To prove the Gospels by a miracle is to prove an absurdity by something contrary to nature.

Wandering in a vast forest at night, I have only a faint light to guide me. A stranger appears and says to me: "My friend, you should blow out your candle in order to find your way more clearly." This stranger is a theologian.

The best doctor is the one you run for and can't find.

The following general definition of an animal: a system of different organic molecules that have combined with one another, under the impulsion of a sensation similar to an obtuse and muffled sense of touch given to them by the creator of matter as a whole, until each one of them has found the most suitable position for it shape and comfort.

How did they meet? By chance, like everybody ... Where did they come from? From the nearest place. Where were they going? Do we know where we are going?

The God of the Christians is a father who makes much of his apples, and very little of his children.

We swallow greedily any lie that flatters us, but we sip only little by little at a truth we find bitter.

The wisest among us is very lucky never to have met the woman, be she beautiful or ugly, intelligent or stupid, who could drive him crazy enough to be fit to be put into an asylum.

Go further, and require each of them to make a contribution: you will see how many things are still missing, and you will be obliged to get the assistance of a large number of men who belong to different classes, priceless men, but to whom the gates of the academies are nonetheless closed because of their social station. All the members of these learned societies are more than is needed for a single object of human science; all the societies together are not sufficient for a science of man in general.

The general interest of the masses might take the place of the insight of genius if it were allowed freedom of action.

I believe in God, although I live very happily with atheists... It is very important not to mistake hemlock for parsley; but not at all so to believe or not in God.

Every man has his dignity. I'm willing to forget mine, but at my own discretion and not when someone else tells me to.

There's a bit of testicle at the bottom of our most sublime feelings and our purest tenderness.
