Science, ever since the time of the Arabs, has had two functions: (1) to enable us to know things, and (2) to enable us to do things.

All men would then be necessarily equal, if they were without needs. It is the poverty connected with our species which subordinates one man to another. It is not inequality which is the real misfortune, it is dependence.

In a valiant suffering for others, not in a slothful making others suffer for us, did nobleness ever lie.

To win a truly great life for the people of Israel, a great peace is necessary, not a fictitious peace, the dwarfish peace that is no more than a feeble intermission, but a true peace with the neighboring peoples, which alone can render possible a common development of this portion of the earth as the vanguard of the awakening Near East.

Close thy Byron; open thy Goethe.

Never for a moment do we lay aside our mistrust of the ideals established by society, and of the convictions which are kept by it in circulation. We always know that society is full of folly and will deceive us in the matter of humanity. ... humanity meaning consideration for the existence and the happiness of individual human beings.

There are clear cases in which "understanding" literally applies and clear cases in which it does not apply; and these two sorts of cases are all I need for this argument.

The real significance of the Russell paradox, from the standpoint of the modal-logic picture, is this: it shows that no concrete structure can be a standard model for the naive conception of the totality of all sets; for any concrete structure has a possible extension that contains more 'sets'. (If we identify sets with the points that represent them in the various possible concrete structures, we might say: it is not possible for all possible sets to exist in any one world!) Yet set theory does not become impossible. Rather, set theory becomes the study of what must hold in, e.g. any standard model for Zermelo set theory.

Language is a part of our organism and no less complicated than it.

But when they have realized that it [society] rejects them forever, they themselves assume the ostracism of which they are victims so as not to leave the initiative to their oppressors.

Thought must be judged by something that is not thought, by its effect on production or its impact on social conduct, as art today is being ultimately gauged in every detail by something that is not art, be it box-office or propaganda value.

If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?

The highest activities are always essentially lonely and private, and these men had a robust sense of their independence and the ultimate self-sufficiency of the mind. In this they were just like Socrates. The only change they operated was to bring philosophy out of the closet into the open, instead of seeking protection behind a little wall like men in a storm. Of course, in so doing they made philosophy, on the one hand, more vulnerable to the public if the hopes of controlling the public are not fulfilled, and, on the other, put at risk that inner intransigence which is the necessary condition of the quest for truth. Not only the rewards but the new responsibilities might prove irresistible temptations to compromise.

In ignoring the important fundamental contribution of the followers of Marx, and by insisting exclusively on the phenomenon of superficial adaptation and variation, Sorel passed in silence over all that was healthy, live and fruitful in the Marxist doctrine.

Value has its own logic. In the constitutional state that is most clearly recognizable in the enactment of its constitution.

Don't discuss yourself, for you are bound to lose; if you belittle yourself, you are believed; if you praise yourself, you are disbelieved.

So that every Crime is a sinne; but not every sinne a Crime.

We can not... escape the conclusion that the rule of reasoning by recurrence is irreducible to the principle of contradiction. ...Neither can this rule come to us from experience... This rule, inaccessible to analytic demonstration and to experience, is the veritable type of the synthetic a priori judgment. On the other hand, we can not think of seeing in it a convention, as in some of the postulates of geometry. ...it is only the affirmation of the power of the mind which knows itself capable of conceiving the indefinite repetition of the same act when once this act is possible. The mind has a direct intuition of this power, and experience can only give occasion for using it and thereby becoming conscious of it.

I bow before the authority of special men because it is imposed upon me by my own reason. I am conscious of my inability to grasp, in all its details and positive developments, any very large portion of human knowledge. The greatest intelligence would not be equal to a comprehension of the whole. Thence results, for science as well as for industry, the necessity of the division and association of labor. I receive and I give - such is human life. Each directs and is directed in his turn. Therefore there is no fixed and constant authority, but a continual exchange of mutual, temporary, and, above all, voluntary authority and subordination.

My father impressed upon me from the first, that the manner in which the world came into existence was a subject on which nothing was known: that the question, "Who made me?" cannot be answered, because we have no experience or authentic information from which to answer it; and that any answer only throws the difficulty a step further back, since the question immediately presents itself, "Who made God?"

Men who prefer any load of infamy, however great, to any pressure of taxation, however light.

It is impossible to feel equal respect for things that are in fact unequal unless the respect is given to something that is identical in all of them. Men are unequal in all their relations with the things of this world, without exception. The only thing that is identical in all men is the presence of a link with the reality outside the world. All human beings are absolutely identical in so far as they can be thought of as consisting of a centre, which is an unquenchable desire for good, surrounded by an accretion of psychical and bodily matter.

What peculiar privilege has this little agitation of the brain which we call thought, that we must thus make it the model of the whole universe? Our partiality in our own favour does indeed present it on all occasions; but sound philosophy ought carefully to guard against so natural an illusion.

We aspire not to equality but to domination. Countries inhabited by foreign races must become again countries of serfs, farm laborers, and factory workers. The goal is not to suppress inequities, but, rather, to amplify them and to make of them a matter of course.

If we are serious about peace, then we must work for it as ardently, seriously, continuously, carefully, and bravely as we have ever prepared for war.

The more intense a spiritual leader's appetite for power, the more he is concerned to limit it to others.

We are spinning our own fates, good or evil, and never to be undone. Every smallest stroke of virtue or of vice leaves its never so little scar. ...Nothing we ever do is, in strict scientific literalness, wiped out.

Among the foundations of the Higher Mathematics is also the 'Idea of a Limit'. The Idea of a Limit cannot be superseded by any other definitions or Hypotheses.

I will begin to speak when I am not going to say what were better left unsaid.

That there is a common cause, an that it is either what we call material progress or something closely connected with material progress, becomes more than an inference when it is noted that the phenomena we class together and speak of as industrial depression are but intensifications of phenomena which always accompany material progress, and which show themselves more clearly and strongly as material progress goes on. Where the conditions to which material progress everywhere tends are the most fully realized-that is to say, where population is densest, wealth greatest, and the machinery of production and exchange most highly developed - we find the deepest poverty, the sharpest struggle for existence, and the most of enforced idleness.

If the slave-owner of our times has no slave, John, whom he can send to the cesspool, he has five shillings, of which hundreds of such Johns are in such need that the slave-owner of our times may choose any one out of hundreds of Johns and be a benefactor to him by giving him the preference, and allowing him, rather than another, to climb down into the cesspool.

History is the life of nations and of humanity. To seize and put into words, to describe directly the life of humanity or even of a single nation, appears impossible.

Wealth begins in a tight roof that keeps the rain and wind out; in a good pump that yields you plenty of sweet water; in two suits of clothes, so to change your dress when you are wet; in dry sticks to burn; in a good double-wick lamp; and three meals; in a horse, or a locomotive, to cross the land; in a boat to cross the sea; in tools to work with; in books to read; and so, in giving, on all sides, by tolls and auxiliaries, the greatest possible extension to our powers, as if it added feet, and hands, and eyes, and blood, length to the day, and knowledge, and good-will.Wealth begins with these articles of necessity.

The dullness of fact is the mother of fiction.

If we accept values as given and consistent, if we postulate an objective description of the world as it really is, and if we assume that the decision maker's computational powers are unlimited, then two important consequences follow. First, we do not need to distinguish between the real world and the decision maker's perception of it: he or she perceives the world as it really is. Second, we can predict the choices that will be made by a rational decision maker entirely from our knowledge of the real world and without a knowledge of the decision maker's perceptions or modes of calculation. (We do, of course, have to know his or her utility function.)

If things emerged from a spaceship which we could not be sure were machines or conscious beings, what we were wondering about would have an answer even if the things were so different from anything we were familiar with that we could never discover it. It would depend on whether there was something it was like to be them, not on whether behavioral similarities warranted our saying so. ... [W]e need ... to ask whether experience is present in [the] alien thing[s], ... whether there is something it is like to be them, and ... the answer to that question is what determines whether they are conscious.

As a social bond, now one does not find even a faith of the warrior kind, that is, relationships of loyalty and honour. The social bond assumes a utilitarian and economic character; it is an agreement based on convenience and material interest - a type only a merchant would accept.

No carelessness in your actions. No confusion in your words. No imprecision in your thoughts. (Hays translation) Be not careless in deeds, nor confused in words, nor rambling in thought.

To require that all of these must be reducible to a single version is to make the mistake of supposing that 'Which are the real objects?' is a question that makes sense independently of our choice of concepts.

Since I have spread my wings to purpose high, The more beneath my feet the clouds I see, The more I give the winds my pinions free, Spurning the earth and soaring to the sky.

If the importation of foreign cattle, for example, were made ever so free, so few could be imported, that the grazing trade of Great Britain could be little affected by it. Live cattle are, perhaps, the only commodity of which the transportation is more expensive by sea than by land.

The end of the philosophical dialogue lies in itself; it can never serve a purpose outside of itself. Just as a sculptor does not cease to be a work of art even if it lies at the bottom of the sea, so indeed every work of philosophy endures, even if uncomprehended in its own time. One would be grateful if it were merely a matter of incomprehension. Instead, the work is usually refitted and appropriated by various entities-some playing the part of the opponent; others, that of the proponent.

Ridicule is the only weapon which can be used against unintelligible propositions. Ideas must be distinct before reason can act upon them; and no man ever had a distinct idea of the trinity. It is the mere Abracadabra of the mountebanks calling themselves the priests of Jesus.

A novel is balanced between a few true impressions and the multitude of false ones that make up most of what we call life. It tells us that for every human being there is a diversity of existences, that the single existence is itself an illusion in part, that these many existences signify something, tend to something, fulfill something; it promises us meaning, harmony, and even justice.

While the art of printing is left to us science can never be retrograde; what is once acquired of real knowlege can never be lost.

I owed a magnificent day to the Bhagavad Gita. It was the first of books; it was as if an empire spoke to us, nothing small or unworthy, but large, serene, consistent, the voice of an old intelligence which in another age and climate had pondered and thus disposed of the same questions which exercise us.

It is an advantage to all narrow wisdom and narrow morals that their maxims have a plausible air; and, on a cursory view, appear equal to first principles. They are light and portable. They are as current as copper coin; and about as valuable. They serve equally the first capacities and the lowest; and they are, at least, as useful to the worst men as to the best. Of this stamp is the cant of not man, but measures; a sort of charm by which many people get loose from every honourable engagement.

The difficulty in our education up till now lies, for the most part, in the fact that knowledge did not refine itself into will, to application of itself, to pure practice. The realists felt the need and supplied it, though in a most miserable way, by cultivating idea-less and fettered "practical men." Most college students are living examples of this sad turn of events. Trained in the most excellent manner, they go on training; drilled they continue drilling.

You must lay aside the burdens of the mind; until you do this, no place will satisfy you.
