Natural Groups are best described, not by any definition which marks their boundaries, but by a 'Type' which marks their centre. The Type of any natural group is an example which possesses in a marked degree all the leading characters of the class.

The human imagination has seldom had before it an object so sublimely ordered as the medieval cosmos. If it has an aesthetic fault, it is perhaps, for us who have known romanticism, a shade too ordered. For all its vast spaces it might in the end afflict us with a kind of claustrophobia. Is there nowhere any vagueness? No undiscovered by-ways? No twilight? Can we never really get out of doors?

Every great study is not only an end in itself, but also a means of creating and sustaining a lofty habit of mind.

There is no need for you to develop an armed insurrection. Christ himself has already begun an insurrection with his mouth.

For a man to love again where he is loved, it is the charity of publicans contracted by mutual profit and good offices; but to love a man's enemies is one of the cunningest points of the law of Christ, and an imitation of the divine nature.

Thou mayest foresee... the things which will be. For they will certainly be of like form, and it is not possible that they should deviate from the order of things now: accordingly to have contemplated human life for forty years is the same as to have contemplated it for ten thousand years.

There is thus a certain plausibility to Nietzsche's doctrine, though it is dynamite. He maintains in effect that the gulf separating Plato from the average man is greater than the cleft between the average man and a chimpanzee.

Even the most humble insect and the most insignificant idea are the military encampments of God. Within them, all of God is arranged in fighting position for a critical battle. Even in the most meaningless particle of earth and sky I hear God crying out: "Help me!" Everything is an egg in which God's sperm labors without rest, ceaselessly. Innumerable forces within and without it range themselves to defend it. With the light of the brain, with the flame of the heart, I besiege every cell where God is jailed, seeking, trying, hammering to open a gate in the fortress of matter, to create a gap through which God may issue in heroic attack.

Since the war began, miles of paper and oceans of ink have been used to prove the barbarity, the cruelty, the oppression of Prussian militarism. Conservatives and radicals alike are giving their support to the Allies for no other reason than to help crush that militarism, in the presence of which, they say, there can be no peace or progress in Europe. But though America grows fat on the manufacture of munitions and war loans to the Allies to help crush Prussians the same cry is now being raised in America which, if carried into national action, would build up an American militarism far more terrible than German or Prussian militarism could ever be, and that because nowhere in the world has capitalism become so brazen in its greed and nowhere is the state so ready to kneel at the feet of capital.

With so many mind-bytes to be downloaded, so many mental codons to be replicated, it is no wonder that child brains are gullible, open to almost any suggestion, vulnerable to subversion, easy prey to Moonies, Scientologists and nuns. Like immune-deficient patients, children are wide open to mental infections that adults might brush off without effort.

Whenever you suffer pain, keep in mind that it's nothing to be ashamed of and that it can't degrade your guiding intelligence, nor keep it from acting rationally and for the common good. And in most cases you should be helped by the saying of Epicurus, that pain is never unbearable or unending, so you can remember these limits and not add to them in your imagination. Remember too that many common annoyances are pain in disguise, such as sleepiness, fever and loss of appetite. When they start to get you down, tell yourself you are giving in to pain.

The telegraph press mosaic is acoustic space as much as an electric circus.

The metaphysical apologia at least betrayed the injustice of the established order through the incongruence of concept and reality. The impartiality of scientific language deprived what was powerless of the strength to make itself heard and merely provided the existing order with a neutral sign for itself. Such neutrality is more metaphysical than metaphysics.

The end of man (as a factual anthropological limit) is announced to thought from the vantage of the end of man (as a determined opening or the infinity of a telos). Man is that which is in relation to his end, in the fundamentally equivocal sense of the word. Since always.

Courage, not cleverness; not even inspiration, is the grain of mustard that grows up to be a great tree.

The universal view melts things into a blur.

Considering the general tendency to multiply offices and dependencies and to increase expense to the ultimate term of burden which the citizen can bear, it behooves us to avail ourselves of every occasion which presents itself for taking off the surcharge; that it never may be seen here that, after leaving to labor the smallest portion of its earnings on which it can subsist, Government shall itself consume the whole residue of what it was instituted to guard.

What are the earth and all its interests beside the deep surmise which pierces and scatters them?

Commit no slander; so that infamy and wickedness may not happen unto thee.

Life is short, but its ills make it seem long.

Virtue can only flourish amongst equals.

Politics and the pulpit are terms that have little agreement.

To suffer is the great modality of taking the world seriously.

Although it is commonly supposed that war making is the specific activity of nations, the blind rage that motivates war destroys the very social bonds that make nations possible. Of course, it can fortify the nationalism of a nation, producing a provisional coherence bolstered by war and enmity, but it also erodes the social relations that make politics possible. The power of destruction unleashed by war breaks social ties and produces anger, revenge, and distrust ("embitterment") such that it becomes unclear whether reparation is possible, undermining not only those relations that may have been built in the past, but also the future possibility of peaceful coexistence.

If our intention now is to reveal classical unreason on its own terms, outside of its ties with dreams and error, it must be understood not as a form of reason that is somehow diseased, lost or mad, but quite simply as reason dazzled.

The proper study of mankind is books.

Absurd, irreducible; nothing - not even a profound and secret delirium of nature - could explain it. Obviously I did not know everything, I had not seen the seeds sprout, or the tree grow. But faced with this great wrinkled paw, neither ignorance nor knowledge was important: the world of explanations and reasons is not the world of existence. A circle is not absurd, it is clearly explained by the rotation of a straight segment around one of its extremities. But neither does a circle exist. This root, on the other hand, existed in such a way that I could not explain it. Reflections on a chestnut tree root.

If A is success in life, then A = x + y + z. Work is x, play is y and z is keeping your mouth shut.

Circumstances (which with some gentlemen pass for nothing) give in reality to every political principle its distinguishing colour, and discriminating effect. The circumstances are what render every civil and political scheme beneficial or noxious to mankind.

The interiorization of the technology of the phonetic alphabet translates man from the magical world of the ear to the neutral visual world.

Pardon one offence and you encourage the commission of many.

Of all the ways whereby children are to be instructed, and their manners formed, the plainest, easiest, and most efficacious, is, to set before their eyes the examples of those things you would have them do, or avoid; which, when they are pointed out to them, in the practice of persons within their knowledge, with some reflections on their beauty and unbecomingness, are of more force to draw or deter their imitation, than any discourses which can be made to them.

The animating purpose of James was, on the other hand, primarily moral and artistic. It is expressed in his phrase, "block universe," employed as a term of adverse criticism. Mechanism and idealism were abhorrent to him because they both hold to a closed universe in which there is no room for novelty and adventure. Both sacrifice individuality and all the values, moral and aesthetic, which hang upon individuality; for according to absolute idealism, as to mechanistic materialism, the individual is simply a part determined by the whole of which he is a part. Only a philosophy of pluralism, of genuine indetermination, and of change which is real and intrinsic gives significance to individuality. It alone justifies struggle in creative activity and gives opportunity for the emergence of the genuinely new.

It pertains to all men to know themselves and to learn self-control.

The question Whether one generation of men has a right to bind another, seems never to have been started either on this or our side of the water. Yet it is a question of such consequences as not only to merit decision, but place also, among the fundamental principles of every government. The course of reflection in which we are immersed here on the elementary principles of society has presented this question to my mind; & that no such obligation can be so transmitted I think very capable of proof. I set out on this ground, which I suppose to be self-evident, 'that the earth belongs in usufruct to the living': that the dead have neither powers nor rights over it. The portion occupied by any individual ceases to be his when himself ceases to be, & reverts to the society.

Normal science, the puzzle-solving activity we have just examined, is a highly cumulative enterprise, eminently successful in its aim, the steady extension of the scope and precision of scientific knowledge. In all these respects it fits with great precision the most usual image of scientific work. Yet one standard product of the scientific enterprise is missing. Normal science does not aim at novelties of fact or theory and, when successful, finds none.

Alcibiades had a very handsome dog, that cost him seven thousand drachmas; and he cut off his tail, "that," said he, "the Athenians may have this story to tell of me, and may concern themselves no further with me."

Nuclear power started in weaponry. It was designed for war. And any instrument that has its origins in war always has the potential for war. First because the material you need to make bombs, you're multiplying it though nuclear power, you're taking uranium and turn it into plutonium. Second by equipping governments and private companies with this potential, in society you spread this potential, that here is a weapon of mass destruction available. This is exactly what happened with fertilizers. Chemical fertilizers came from explosive factories are increasingly used in terrorist attacks.

The ones who are preoccupied by logic are above all; to read their works, one is tempted to believe they have advanced only step by step, after the manner of a Vauban who pushes on his trenches against the place besieged, leaving nothing to chance. The others are guided by intuition and, at the first stroke, make quick but sometimes precarious conquests, like bold cavalrymen of the advance guard.

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).

That books do not take the place of experience, and that learning is no substitute for genius, are two kindred phenomena; their common ground is that the abstract can never take the place of the perceptive.

Oh, can I really believe the poet's tales, that when one first sees the object of one's love, one imagines one has seen her long ago, that all love like all knowledge is remembrance, that love too has its prophecies in the individual. ... it seems to me that I should have to possess the beauty of all girls in order to draw out a beauty equal to yours; that I should have to circumnavigate the world in order to find the place I lack and which the deepest mystery of my whole being points towards, and at the next moment you are so near to me, filling my spirit so powerfully that I am transfigured for myself, and feel that it's good to be here.

It is not so much what you believe in that matters, as the way in which you believe it and proceed to translate that belief into action.

The "message" of any medium or technology is the change of scale or pace or pattern that it introduces into human affairs.

Belief in eternal hell fire was an essential item of Christian belief until pretty recent times. In this country, as you know, it ceased to be an essential item because of a decision of the Privy Council, and from that decision the Archbishop of Canterbury and the Archbishop of York dissented; but in this country our religion is settled by Act of Parliament, and therefore the Privy Council was able to override Their Graces and hell was no longer necessary to a Christian. Consequently I shall not insist that a Christian must believe in hell. What is a Christian?

It is so by nature that the plant will develop with regularity, that the animal will move purposefully, and that human beings will think. Why should I take exception to recognizing also the last as the expression of an original force of nature, as I do the first and the second?

I am dreaming ...? Let me dream, if this dream is my life. Do not awaken me from it. I believe in the immortal origin of this yearning for immortality, which is the very substance of my soul. But do I really believe in it ...? And wherefore do you want to be immortal? you ask me, wherefore? Frankly, I do not understand the question, for it is to ask the reason of the reason, the end of the end, the principle of the principle.
