For the things we have to learn before we can do, we learn by doing.

The need of a constantly expanding market for its products chases the bourgeoisie over the whole surface of the globe. It must nestle everywhere, settle everywhere, establish connections everywhere.

I believe that the nature of man is a contradiction rooted in the conditions of human existence that requires a search for solutions, which in their turn create new contradictions and now the need for answers. I believe that every answer to these contradictions can really satisfy the condition of helping man to overcome the sense of separation and to achieve a sense of agreement, of unity, and of belonging. I believe that in every answer to these contradictions, man has the possibility of choosing only between going forward or going back; these choices, which are translated into specific actions, are means toward the regressing or toward the progressing of the humanity that is in us.

Brutes are merely brutal; men and women are capable of being devils and lunatics. They are no less capable of being fully human-even, occasionally, of being a bit more than fully human, of being saints, heroes and geniuses.

What! the inventors of ancient civilisations, the first makers of tools and tape lines, the first builders of vehicles, ships, and houses, the first observers of the laws of the heavens and the multiplication tables is it contended that they were entirely different from the inventors and observers of our own time, and superior to them? And that the first slow steps forward were of a value which has not been equalled by the discoveries we have made with all our travels and circumnavigations of the earth?

Égalité is an expression of envy. It means, in the real heart of every Republican, " No one shall be better off than I am;" and while this is preferred to good government, good government is impossible.

Who then to frail mortality shall trust But limns the water, or but writes in dust.

Only the idiot is equipped to breathe.

We have no reason to fear lest a habit of conscientious inquiry should paralyse the actions of our daily life. But because it is not enough to say, "It is wrong to believe on unworthy evidence," without saying also what evidence is worthy, we shall now go on to inquire under what circumstances it is lawful to believe on the testimony of others; and then, further, we shall inquire more generally when and why we may believe that which goes beyond our own experience, or even beyond the experience of mankind.

The many are mean; only the few are noble.

The revolution must end and the republic must begin. In our constitution, right must take the place of duty, welfare that of virtue, and self-defense that of punishment. Everyone must be able to prevail and to live according to one's own nature.

Yes, truly, it is a great thing for a Nation that it get an articulate voice; that it produce a man who will speak forth melodiously what the heart of it means!

The end of living, or the ultimate good, which is to be sought for its own sake, according to the universal opinion of mankind, is happiness; yet men, for the most part, fail in the pursuit of this end, either because they do not form a right idea of the nature of happiness, or because they do not make use of proper means to attain it.

France has always more or less influenced manners in England; and when your fountain is choked up and polluted, the stream will not run long, or not run clear, with us, or perhaps with any nation. This gives all Europe, in my opinion, but too close and connected a concern in what is done in France. Excuse me, therefore, if I have dwelt too long on the atrocious spectacle of the 6th of October, 1789, or have given too much scope to the reflections which have arisen in my mind on occasion of the most important of all revolutions, which may be dated from that day, I mean a revolution in sentiments, manners, and moral opinions.

It is forbidden to kill; therefore all murderers are punished unless they kill in large numbers and to the sound of trumpets.

A Dialogue between two Infants in the womb concerning the state of this world, might handsomely illustrate our ignorance of the next, whereof methinks we yet discourse in Plato's Den, and are but Embryon Philosophers.

But perhaps I lack the gift. I see I've described her as being like a sword. That's true as far as it goes. But utterly inadequate by itself, and misleading. I ought to have said 'But also like a garden. Like a nest of gardens, wall within wall, hedge within hedge, more secret, more full of fragrant and fertile life, the further you explore.' And then, of her, and every created thing I praise, I should say 'in some way, in its unique way, like Him who made it.' Thus up from the garden to the Gardener, from the sword to the Smith. to the life-giving Life and the Beauty that makes beautiful.

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

The mental operation by which one achieves new concepts and which one denotes generally by the inadequate name of induction is not a simple but rather a very complicated process. Above all, it is not a logical process although such processes can be inserted as intermediary and auxiliary links. The principle effort that leads to the discovery of new knowledge is due to abstraction and imagination.

I am happy because I want nothing from anyone. I do not care about money. Decorations, titles or distinctions mean nothing to me. I do not crave praise. The only thing that gives me pleasure, apart from my work, my violin, and my sailboat, is the appreciation of my fellow workers.

I do not think it can be questioned that sympathy is a genuine motive, and that some people at some times are made somewhat uncomfortable by the sufferings of some other people. It is sympathy that has produced the many humanitarian advances of the last hundred years. We are shocked when we hear stories of the ill-treatment of lunatics, and there are now quite a number of asylums in which they are not ill-treated. Prisoners in Western countries are not supposed to be tortured, and when they are, there is an outcry if the facts are discovered. We do not approve of treating orphans as they are treated in Oliver Twist.

The first duty of a man is the seeking after and the investigation of truth.

We have unmistakable proof that throughout all past time, there has been a ceaseless devouring of the weak by the strong.

At the present time a serious, strong state can have but one sound foundation - military and bureaucratic centralization. Between a monarchy and the most democratic republic there is only one essential difference: in the former, the world of officialdom oppresses and robs the people for the greater profit of the privileged and propertied classes, as well as to line its own pockets, in the name of the monarch; in the latter, it oppresses and robs the people in exactly the same way, for the benefit of the same classes and the same pockets, but in the name of the people's will. In a republic a fictitious people, the "legal nation" supposedly represented by the state, smothers the real, live people. But it will scarcely be any easier on the people if the cudgel with which they are beaten is called the people's cudgel.

In peace, as a wise man, he should make suitable preparation for war.

I remind young people everywhere I go, one of the worst things the older generation did was to tell them for twenty-five years "Be successful, be successful, be successful" as opposed to "Be great, be great, be great". There's a qualitative difference.

History is the essence of innumerable biographies.

Patriotism is an ephemeral motive that scarcely ever outlasts the particular threat to society that aroused it.

The self-evident truth which makes men invincible is that inalienably they are inviolate persons.

Logic takes care of itself; all we have to do is to look and see how it does it.

Every true thinker for himself is so far like a monarch; he is absolute, and recognises nobody above him. His judgments, like the decrees of a monarch, spring from his own sovereign power and proceed directly from himself. He takes as little notice of authority as a monarch does of a command; nothing is valid unless he has himself authorised it. On the other hand, those of vulgar minds, who are swayed by all kinds of current opinions, authorities, and prejudices, are like the people which in silence obey the law and commands.

An avidity to punish is always dangerous to liberty. It leads men to stretch, to misinterpret, and to misapply even the best of laws. He that would make his own liberty secure must guard even his enemy from oppression; for if he violates this duty he establishes a precedent that will reach to himself.

It is the highest impertinence and presumption, therefore, in kings and ministers, to pretend to watch over the economy of private people, and to restrain their expence, either by sumptuary laws, or by prohibiting the importation of foreign luxuries. They are themselves always, and without any exception, the greatest spendthrifts in the society. Let them look well after their own expence, and they may safely trust private people with theirs. If their own extravagance does not ruin the state, that of their subjects never will.

Such delusions of grandeur to think that a God with a hundred billion galaxies on his mind would give a tuppenny damn who you sleep with, or indeed whether you believe in him.

Time which antiquates Antiquities, and hath an art to make dust of all things.

May not we then confidently pronounce that man happy who realizes complete goodness in action, and is adequately furnished with external goods? Or should we add, that he must also be destined to go on living not for any casual period but throughout a complete lifetime in the same manner, and to die accordingly, because the future is hidden from us, and we conceive happiness as an end, something utterly and absolutely final and complete? If this is so, we shall pronounce those of the living who possess and are destined to go on possessing the good things we have specified to be supremely blessed, though on the human scale of bliss.

I am conscious that an equal division of property is impracticable. But the consequences of this enormous inequality producing so much misery to the bulk of mankind, legislators cannot invent too many devices for subdividing property..a means of silently lessening the inequality of property is to exempt all from taxation below a certain point, and to tax the higher portions of property in geometrical progression as they rise.

All too often people forget that spirituality is essentially a way of life and that its measure does not consist of notions, theories, and ideas that have been stored in one's head. Spirituality is actually what has been successfully actualized and translated into a sense of superiority which is experienced inside by the soul, and a noble demeanor, which is expressed in the body.

A good education would be devoted to encouraging and refining the love of the beautiful, but a pathologically misguided moralism instead turns such longing into a sin against the high goal of making everyone feel good, of overcoming nature in the name of equality. ... Love of the beautiful may be the last and finest sacrifice to radical egalitarianism.

I decline the election. - It has ever been my rule through life, to observe a proportion between my efforts and my objects. I have never been remarkable for a bold, active, and sanguine pursuit of advantages that are personal to myself.

Whatever moral rules you have deliberately proposed to yourself abide by them as they were laws, and as if you would be guilty of impiety by violating any of them. Don't regard what anyone says of you, for this, after all, is no concern of yours. How long, then, will you put off thinking yourself worthy of the highest improvements and follow the distinctions of reason? You have received the philosophical theorems, with which you ought to be familiar, and you have been familiar with them. What other master, then, do you wait for, to throw upon that the delay of reforming yourself?... Let whatever appears to be the best be to you an inviolable law.

A man, in so far as he is an individual, may be very sharply detached from others, a sort of spiritual crustacean, and yet be very poor in differentiating content. And further, it is true on the other hand that the more personality a man has and the greater his interior riches and the more he is a society within himself, the less brusquely he is divided from his fellows.

The atheist who affects to reason, and the fanatic who rejects reason, plunge themselves alike into inextricable difficulties. The one perverts the sublime and enlightening study of natural philosophy into a deformity of absurdities by not reasoning to the end. The other loses himself in the obscurity of metaphysical theories, and dishonours the Creator, by treating the study of his works with contempt. The one is a half-rational of whom there is some hope, the other a visionary to whom we must be charitable.

Let me give two cautions. 1) The one is, that you keep them to the practice of what you would have grow into a habit with them, by kind words, and gentle admonitions, rather as minding them of what they forget, than by harsh rebukes and chiding, as if they were wilfully guilty. 2) Another thing you are to take care of, is, not to endeavour to settle too many habits at once, lest by variety you confound them, and so perfect none. When constant custom has made any one thing easy and natural to 'em, and they practice it without reflection, you may then go on to another.

I live only because it is in my power to die when I choose to: without the idea of suicide, I'd have killed myself right away.

A specter haunts the world and it is the specter of migration.
