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.

And when we speak of "abandonment" - a favorite word of Heidegger - we only mean to say that God does not exist and that it is necessary to draw the consequences of his absence to the end.

Once we begin to want, we fall under the jurisdiction of the Devil.

The world is nothing, the man is all; in yourself is the law of all nature, and you know not yet how a globule of sap ascends; in yourself slumbers the whole of Reason; it is for you to know all, it is for you to dare all.

Blast Sputnik for closing terrestrial nature in a man-made environment that transfers the evolutionary process from biology to technology.

But if ether is nothing but an hypothesis explanatory of light, air on the other hand, is a thing that is directly felt; and even if it did not enable us to explain the phenomenon of sound, we should nevertheless always be directly aware of it, and above all, of the lack of it in moments of suffocation or air-hunger. And in the same way God Himself, not the idea of God, may become a reality that is immediately felt; and even though the idea of God does not enable us to explain either the existence or essence of the Universe, we have at times the direct feeling of God, above all in moments of spiritual suffocation. And the feeling, mark it well, for all that is tragic in it and the whole tragic sense of life is founded upon this - this feeling is a feeling of hunger for God, of the lack of God. To believe in God is, in the first instance... to wish that there may be a God, to be unable to live without Him.

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.

It is often asserted that discussion is only possible between people who have a common language and accept common basic assumptions. I think that this is a mistake. All that is needed is a readiness to learn from one's partner in the discussion, which includes a genuine wish to understand what he intends to say. If this readiness is there, the discussion will be the more fruitful the more the partner's backgrounds differ.

As we divided natural philosophy in general into the inquiry of causes, and productions of effects: so that part which concerneth the inquiry of causes we do subdivide according to the received and sound division of causes. The one part, which is physic, inquireth and handleth the material and efficient causes; and the other, which is metaphysic, handleth the formal and final causes.

The advantage of meditating upon life and death is being able to say anything at all about them.

The poor are thought to be dangerous, either morally dangerous because they are unproductive social parasites - thieves, prostitutes, drug addicts, and the like - or potentially dangerous because they are disorganized, unpredictable, and tendentially reactionary. In fact the term lumpenproletariat (or rad proletariat) has functioned for times to demonize the poor as a whole. ... The industrial reserve army is a constant threat hanging over the heads of the existing working class because, first of all, its misery serves as a terrifying example to workers of what could happen to them, and, second, the excess supply of labor it represents lowers the costs of labor and undermines workers' power against employers (by serving potentially as strike breakers, for example).

Not because Socrates said so, but because it is in truth my own disposition - and perchance to some excess - I look upon all men as my compatriots, and embrace a Pole as a Frenchman, making less account of the national than of the universal and common bond.

The worker's existence is thus brought under the same condition as the existence of every other commodity. The worker has become a commodity, and it is a bit of luck for him if he can find a buyer, And the demand on which the life of the worker depends, depends on the whim of the rich and the capitalists.

Do you count your birthdays with gratitude?

No place in the world has had a comparable role to that of the nameless mountain or valley where mankind first attained self-consciousness. Let us be proud ... of the old patriarchs who, at the foot of Imaiis, laid the foundations of what we are and of what we shall become.

If there be light, then there is darkness; if cold, heat; if height, depth; if solid, fluid; if hard, soft; if rough, smooth; if calm, tempest; if prosperity, adversity; if life, death.

These are the visionary, mystical moments, when a man 'completes his partial mind'. His everyday conscious self is only a small part of the mind, like the final crescent of the moon. In moments of crisis, the full moon suddenly appears.

They should always be heard, and fairly and kindly answer'd, when they ask after any thing they would know, and desire to be informed about. Curiosity should be as carefully cherish'd in children, as other appetites suppress'd.

He is dead, and my hatred has died with him.

Science seems to be at war with itself.... Naive realism leads to physics, and physics, if true, shows naive realism to be false. Therefore naive realism, if true, is false; therefore it is false.

The Jesuits founded their politics on the virtual disappearance of God and on the worldly and spectacular manipulation of consciences-the evanescence of God in the epiphany of power-the end of transcendence, which now only serves as an alibi for a strategy altogether free of influences and signs. Behind the baroqueness of images hides the éminence grise of politics.

The end of government is to make the governed and the governors happy. That government then is thebest, which in practice produces the greatest happiness to the greatest number; including those who govern, and those who obey.

To rule the imperial population, behold our vocation.

Most of what we strive for in our modern life uses the apparatus of goal seeking that was originally set up to seek goals in the state of nature.

Freedom and not servitude is the cure of anarchy; as religion, and not atheism, is the true remedy for superstition.

Many conflicts within Third World countries are related to the practice of exploiting resources faster than nature can renew them or diverting them away from where people need them. Dams in every society have become major sources of conflict. As water scarcity grows, neighbors, families turn against each other.

Among a people without fellow-feeling, especially if they read and speak different languages, the united public opinion, necessary to the working of the representative government, cannot exist.

God looks at the clean hands, not the full ones.

Define your terms, you will permit me again to say, or we shall never understand one another.

Neither of us cares a straw for popularity. A proof of this is for example, that, because of aversion to any personality cult, I have never permitted the numerous expressions of appreciation from various countries with which I was pestered during the existence of the International to reach the realm of publicity, and have never answered them, except occasionally by a rebuke. When Engels and I first joined the secret Communist Society we made it a condition that everything tending to encourage superstitious belief in authority was to be removed from the statutes.

There is endless merit in a man's knowing when to have done.

Let us apply these principles to adultery. The state can no more prohibit it or punish it by law than any other illegitimate satisfaction of the sexual impulse.

The historical world, in so far as it is built, organized, and shaped by the conscious activity of thinking subjects, is a realm of mind. But the mind is fully realized and exists in its true form only when it indulges in its proper activity, namely, in art, religion, and philosophy.

Great minds are related to the brief span of time during which they live as great buildings are to a little square in which they stand: you cannot see them in all their magnitude because you are standing too close to them.

Who is there that can recognize real intellect, and do reverence to it; and discriminate it well from sham intellect, which is so much more abundant, and deserves the reverse of reverence? He that himself has it!-One really human Intellect, invested with command, and charged to reform Downing Street for us, would continually attract real intellect to those regions, and with a divine magnetism search it out from the modest corners where it lies hid. And every new accession of intellect to Downing Street would bring to it benefit only, and would increase such divine attraction in it, the parent of all benefit there and elsewhere!

The Few assume to be the deputies, but they are often only the despoilers of the Many.

The natural philosophy of Democritus and some others, who did not suppose a mind or reason in the frame of things, but attributed the form thereof able to maintain itself to infinite essays or proofs of nature, which they term fortune, seemeth to me... in particularities of physical causes more real and better inquired than that of Aristotle and Plato; whereof both intermingled final causes, the one as a part of theology, and the other as a part of logic, which were the favourite studies respectively of both those persons. Not because those final causes are not true, and worthy to be inquired, being kept within their own province; but because their excursions into the limits of physical causes hath bred a vastness and solitude in that tract.

"What is truth?" is a fundamental question. But what is it compared to "How to endure life?" And even this one pales beside the next: "How to endure oneself?" - That is the crucial question in which no one is in a position to give us an answer.

Only when they must choose between competing theories do scientists behave like philosophers.

I take it for granted, when I am invited to lecture anywhere, - for I have had a little experience in that business, - that there is a desire to hear what I think on some subject, though I may be the greatest fool in the country, - and not that I should say pleasant things merely, or such as the audience will assent to; and I resolve, accordingly, that I will give them a strong dose of myself. They have sent for me, and engaged to pay for me, and I am determined that they shall have me, though I bore them beyond all precedent.

Now in all of us, however constituted, but to a degree the greater in proportion as we are intense and sensitive and subject to diversified temptations, and to the greatest possible degree if we are decidedly psychopathic, does the normal evolution of character chiefly consist in the straightening out and unifying of the inner self. The higher and the lower feelings, the useful and the erring impulses, begin by being a comparative chaos within us - they must end by forming a stable system of functions in right subordination. Unhappiness is apt to characterize the period of order-making and struggle.

Thought is only a flash between two long nights, but this flash is everything.

Now, as there is an infinity of possible universes in the Ideas of God, and as only one of them can exist, there must be a sufficient reason for God's choice, which determines him toward one rather than another. And this reason can be found only in the fitness, or the degrees of perfection, that these worlds contain, since each possible thing has the right to claim existence in proportion to the perfection it involves.

Hungary conquered and in chains has done more for freedom and justice than any people for twenty years. But for this lesson to get through and convince those in the West who shut their eyes and ears, it was necessary, and it can be no comfort to us, for the people of Hungary to shed so much blood which is already drying in our memories. In Europe's isolation today, we have only one way of being true to Hungary, and that is never to betray, among ourselves and everywhere, what the Hungarian heroes died for, never to condone, among ourselves and everywhere, even indirectly, those who killed them. It would indeed be difficult for us to be worthy of such sacrifices.

Unless some Hero-worship, in its new appropriate form, can return, this world does not promise to be very habitable long.

What terrible tragedies realism inflicts on people.'

We feel and know that we are eternal.

Most of the texts... preserved from this period come from writers... either... affiliated with the aristocratic party, or... distrustful of democratic or radically democratic institutions.
