We distinguish diagrammatic from sentential paper-and-pencil representations of information by developing alternative models of information-processing systems that are informationally equivalent and that can be characterized as sentential or diagrammatic. Sentential representations are sequential, like the propositions in a text. Diagrammatic representations are indexed by location in a plane. Diagrammatic representations also typically display information that is only implicit in sentential representations and that therefore has to be computed, sometimes at great cost, to make it explicit for use. We then contrast the computational efficiency of these representations for solving several.illustrative problems in mathematics and physics.

I hold it, that a little rebellion, now and then, is a good thing, and as necessary in the political world as storms in the physical.

There's nothing under the ground that's worthmore than the little layer of topsoil sitting on top of it.

Environments are not just containers, but are processes that change the content totally.

Every one who has a heart and eyes sees that you, working men, are obliged to pass your lives in want and in hard labor, which is useless to you, while other men, who do not work, enjoy the fruits of your labor-that you are the slaves of these men, and that this ought not to exist.

The composer reveals the innermost nature of the world, and expresses the profoundest wisdom in a language that his reasoning faculty does not understand, just as a magnetic somnambulist gives information about things of which she has no conception when she is awake. Therefore in the composer, more than in any other artist, the man is entirely separate and distinct from the artist.

Most shocking of all is alledging the Sacred Scriptures to favour this wicked practice. One would have thought none but infidel cavillers would endeavour to make them appear contrary to the plain dictates of natural light, and Conscience, in a matter of common Justice and Humanity; which they cannot be. Such worthy men, as referred to before, judged otherways; Mr. Baxter declared, the Slave-Traders should be called Devils, rather than Christians; and that it is a heinous crime to buy them.

The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, scepticism is the highest of duties; blind faith the one unpardonable sin. And it cannot be otherwise, for every great advance in natural knowledge has involved the absolute rejection of authority, the cherishing of the keenest scepticism, the annihilation of the spirit of blind faith; and the most ardent votary of science holds his firmest convictions, not because the men he most venerates hold them; not because their verity is testified by portents and wonders; but because his experience teaches him that whenever he chooses to bring these convictions into contact with their primary source, Nature - whenever he thinks fit to test them by appealing to experiment and to observation - Nature will confirm them. The man of science has learned to believe in justification, not by faith, but by verification. On the advisableness of improving natural knowledge

I propose to value them according to their character, and not according to their duties. Each man acquires his character for himself, but accident assigns his duties.

Power is not opposed to freedom. It is precisely freedom that distinguishes power from violence or coercion.

I know of no country in which there is so little independence of mind and real freedom of discussion as in America.

Lifetime is a child at play, moving pieces in a game.

If nonviolence is to make sense as an ethical and political position, it cannot simply repress aggression or do away with its reality; rather, nonviolence emerges as a meaningful concept precisely when destruction is most likely or seems most certain.

Good bye, proud world! I'm going home; Thou art not my friend; I am not thine.

The words that reverberate for us at the confines of this long adventure of rebellion are not formulas for optimism, for which we have no possible use in the extremities of our unhappiness, but words of courage and intelligence which, on the shores of the eternal seas, even have the qualities of virtue.

The youth gets together his materials to build a bridge to the moon, or, perchance, a palace or temple on the earth, and, at length, the middle-aged man concludes to build a woodshed with them.

Pyrrhus said, "If I should overcome the Romans in another fight, I were undone."

All these people talk so eloquently about getting back to good old-fashioned values. Well, as an old poop I can remember back to when we had those old-fashioned values, and I say let's get back to the good old-fashioned First Amendment of the good old-fashioned Constitution of the United States-and to hell with the censors! Give me knowledge or give me death!

There must have been many who had a relationship to Jesus similar to that of Barabbas (his name was Jesus Barrabas). The Danish "Barrabas" is about the same as "N.N." [Mr. X or John Doe], filius patris, his father's son. - It is too bad, however, that we do not know anything more about Barrabas; it seems to me that in many ways he could have become a counterpart to the Wandering Jew. The rest of his life must have taken a singular turn. God knows whether or not he became a Christian. - It would be a poetic motif to have him, gripped by Christ's divine power, step forward and witness for him.

My conduct must be the best proof, the moral proof, of my supreme desire; and if I do not end by convincing myself, within the bounds of the ultimate and irremediable uncertainty of the truth of what I hope for, it is because my conduct is not sufficiently pure. Virtue, therefore, is not based upon dogma, but dogma upon virtue, and it is not faith that creates martyrs but martyrs who create faith. There is no security or repose - so far as security and repose are obtainable in this life, so essentially insecure and unreposeful - save in conduct that is passionately good.

Philosophy, as I understand the word, is a positive theoretical science, and a science in an early stage of development. As such it has no more to do with belief than any other science. Indeed, I am bound to confess that it is at present in so unsettled a condition, that if the ordinary theorems of molecular physics and of archaeology are but the ghosts of beliefs, then to my mind, the doctrines of the philosophers are little better than the ghosts of ghosts. I know this is an extremely heretical opinion.

As you say of yourself, I too am an Epicurian. I consider the genuine (not the imputed) doctrines of Epicurus as containing everything rational in moral philosophy which Greece and Rome have left us.

Valour, however unfortunate, commands great respect even from enemies: but the Romans despise cowardice, even though it be prosperous.

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 ...

For is not a Symbol ever, to him who has eyes for it, some dimmer or clearer revelation of the God-like? B

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

But there has also been the rise of populist movements within existing liberal democracies, and particularly within the United States and Britain, which were... the leaders of the neoliberal revolution... in the 1980s...

We have been Godlike in our planned breeding of our domesticated plants and animals, but we have been rabbitlike in our unplanned breeding of ourselves.

Intuitionism is not constructive, perfectionism is unacceptable.

Time with its continuity logically involves some other kind of continuity than its own. Time, as the universal form of change, cannot exist unless there is something to undergo change, and to undergo a change continuous in time, there must be a continuity of changeable qualities.

No one can flatter himself that he is immune to the spirit of his own epoch, or even that he possesses a full understanding of it. Irrespective of our conscious convictions, each one of us, without exception, being a particle of the general mass, is somewhere attached to, colored by, or even undermined by the spirit which goes through the mass. Freedom stretches only as far as the limits of our consciousness.

The law of progress holds that everything now must be better than what was there before. Don't you see if you want something better, and better, and better, you lose the good? The good is no longer even being measured.

To claim you are more detached, more alien to everything than anyone, and to be merely a fanatic of indifference!

The evidence of our own eyes makes it more plausible to believe that the world was not created by any god at all. If, however, we insist on believing in divine creation, we are forced to admit that the god who made the world cannot be all-powerful and all good. He must be either evil or a bungler.

The man of flesh and bone; the man who is born, suffers, and dies-above all, who dies; the man who eats and drinks and plays and sleeps and thinks and wills; the man who is seen and heard; the brother, the real brother.

I strive to discover how to signal my companions before I die, how to give them a hand, how to spell out for them in time one complete word at least, to tell them what I think this procession is, and toward what we go. And how necessary it is for all of us together to put our steps and hearts in harmony. To say in time a simple word to my companions, a password, like conspirators. Yes, the purpose of Earth is not life, it is not man. Earth has existed without these, and it will live on without them. They are but the ephemeral sparks of its violent whirling. Let us unite, let us hold each other tightly, let us merge our hearts, let us create - so long as the warmth of this earth endures, so long as no earthquakes, cataclysms, icebergs or comets come to destroy us - let us create for Earth a brain and a heart, let us give a human meaning to the superhuman struggle. This anguish is our second duty.

Opinions differ as to the reasons why he became the futile laborer of the underworld. To begin with, he is accused of a certain levity in regard to the gods. He stole their secrets.

What you see, yet can not see over, is as good as infinite.

In writing a history of madness, Foucault has attempted-and this is the greatest merit, but also the very infeasibility of his book-to write a history of madness itself. Itself.

The created World is but a small Parenthesis in Eternity.

Only thoughts that are randomly born die. The other thoughts we carry with us without knowing them. They have abandoned themselves to forgetfulness so that they can be with us all the time.

Whereas, our tenet ever was, and, indeed, it is almost the only landmark which now divides the federalists from the republicans, that Congress had not unlimited powers to provide for the general welfare, but were restrained to those specifically enumerated;...

Movement in direct experience is alteration in the qualities of objects, and space as experienced is an aspect of this qualitative change. Up and down, back and front, to and fro, this side and that- or right and left- here and there, feel differently. The reason they do is that they are not static points in something itself static, but objects in movement, qualitative changes of value. For "back" is short for backwards and front for forwards. So with velocity. Mathematically there are no such things as fast and slow. They mark simply greater and less on a number scale. As experienced they are qualitatively as unlike as noise and silence, heat and cold, black and white. To be forced to wait a long time for an important event to happen is a length very different from that measured by the movements of the hands of a clock. It is something qualitative.

I plead guilty to valuing such a man beyond all other sorts of men. Smooth-shaven Respectabilities not a few one finds, that are not good for much. Small thanks to a man for keeping his hands clean, who would not touch the work but with gloves on!
