Acoustic space is totally discontinuous, like touch. It is a sphere without centers or margins.

Material production - the production, for example, or cars, televisions, clothing, and food - creates the means of social life. ... Immaterial production, by contrast, including the production of ideas, knowledges, communication, cooperation, and affective relations, tends to create not the means of social life but social life itself. (146)

In history, we are concerned with what has been and what is; in philosophy, however, we are concerned not with what belongs exclusively to the past or to the future, but with that which is, both now and eternally - in short, with reason.

The last fact which knowledge can discover is that the world is a manifestation, and in every way a puzzling manifestation, of the universal will to live.

To look for a single general theory of how to decide the right thing to do is like looking for a single theory of how to decide what to believe.

Study carefully, the character of the one you recommend, lest their misconduct bring you shame.

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.

We have seen how it is originally language which works on the construction of concepts, a labor taken over in later ages by science. Just as the bee simultaneously constructs cells and fills them with honey, so science works unceasingly on this great columbarium of concepts, the graveyard of perceptions.

What is not heartrending is superfluous, at least in music.

Martyrs must choose between being forgotten, mocked, or made use of. As for being understood, never!

And yet this might not necessarily involve the conversion of the Trinity into a Quaternity. If... in Greek, spirit, instead of being neuter had been feminine, who can say that the Virgin Mary might not already have become an incarnation or humanization of the Holy Spirit? ...And thus a dogmatic evolution would have been effected parallel to that of the divinization of Jesus, the Son, and his identification with the Word.

The only originality I claim is that for me this truth goes hand in hand with the intellectual certainty that the human spirit is capable of creating in our time a new mentality, an ethical mentality. Inspired by this certainty, I too proclaim this truth in the hope that my testimony may help to prevent its rejection as an admirable sentiment but a practical impossibility. Many a truth has lain unnoticed for a long time, ignored simply because no one perceived its potential for becoming reality.

Those who assert that the mathematical sciences say nothing of the beautiful or the good are in error. For these sciences say and prove a great deal about them; if they do not expressly mention them, but prove attributes which are their results or definitions, it is not true that they tell us nothing about them. The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree.

Better be mute, than dispute with the Ignorant.

Philosophy was never just ontotheology, and even when philosophers were concerned with ontotheology, they were concerned with much more than that. That is the first reason that the idea of a fundamental "crisis" in philosophy and of the "end of philosophy" is deeply mistaken. And if the questions of philosophy are indeed "unsettleable," in the sense that they will always be with us, that is a wonderful thing, not something to be regretted.

The owl of Minerva first begins her flight with the onset of dusk.

Only lies and evil come from letting people off.

In a free nation, it matters not whether individuals reason well or ill; it is sufficient that they do reason. Truth arises from the collision and from hence springs liberty, which is a security from the effects of reasoning.

He who would write heroic poems should make his whole life a heroic poem.

The Constitution has made no provision for our holding foreign territory, still less for incorporating foreign nations into our Union. The Executive, in seizing the fugitive occurrence which so much advances the good of their country, have done an act beyond the Constitution. The Legislature, in casting behind them metaphysical subtleties and risking themselves like faithful servants, must ratify and pay for it, and throw themselves on their country for doing for them unauthorized what we know they would have done for themselves had they been in a situation to do it.

I may not be as unambiguously hostile to capitalism as many people are, but what I don't like about it is the commodification of personal experiences, it turns everyone into actors.

Freedom of opinion can only exist when the government thinks itself secure...

But if you can breed cattle for milk yield, horses for running speed, and dogs for herding skill, why on Earth should it be impossible to breed humans for mathematical, musical or athletic ability? Objections such as "these are not one-dimensional abilities" apply equally to cows, horses and dogs and never stopped anybody in practice. I wonder whether, some 60 years after Hitler's death, we might at least venture to ask what the moral difference is between breeding for musical ability and forcing a child to take music lessons. Or why it is acceptable to train fast runners and high jumpers but not to breed them. I can think of some answers, and they are good ones, which would probably end up persuading me. But hasn't the time come when we should stop being frightened even to put the question? 

We will not praise Mahomet's moral precepts as always of the superfinest sort; yet it can be said that there is always a tendency to good in them; that they are the true dictates of a heart aiming towards what is just and true.

If one rejects laissez faire on account of man's fallibility and moral weakness, one must for the same reason also reject every kind of government action.

This is the Supreme Duty of the man who struggles - to set out for the lofty peak which Christ, the first-born sone of salvation, attained. How can we begin? If we are to follow him we must have a profound knowledge of his conflict, we must relive his anguish: his victory over the blossoming snares of the earth, his sacrifice of the great and small joys of men and his ascent from sacrifice to sacrifice, exploit to exploit, to martyrdom's summit, the Cross.

God offers to every mind its choice between truth and repose.

The ordinary logic has a great deal to say about genera and species, or in our nineteeth century dialect, about classes. Now a class is a set of objects comprising all that stand to one another in a special relation of similarity. But where ordinary logic talks of classes the logic of relatives talks of systems. A system is a set of objects comprising all that stands to one another in a group of connected relations. Induction according to ordinary logic rises from the contemplation of a sample of a class to that of a whole class; but according to the logic of relatives it rises from the comtemplation of a fragment of a system to the envisagement of the complete system.

The people who are regarded as moral luminaries are those who forego ordinary pleasures themselves and find compensation in interfering with the pleasures of others.

Let us suppose that a man believes in eternal life on Christ's word. In that case he believes without any fuss about being profound and searching and philosophical and racking his brains.

Although objectively greater demands are placed on this authority, it operates less as a public opinion giving a rational foundation to the exercise of political and social authority, the more it is generated for the purpose of an abstract vote that amounts to no more than an act of acclamation within a public sphere temporarily manufactured for show or manipulation.

I cannot believe - and I say this with all the emphasis of which I am capable - that there can ever be any good excuse for refusing to face the evidence in favour of something unwelcome. It is not by delusion, however exalted, that mankind can prosper, but only by unswerving courage in the pursuit of truth.

We ourselves are the entities to be analyzed.

The world would be a happier place than it is if acquisitiveness were always stronger than rivalry. But in fact, a great many men will cheerfully face impoverishment if they can thereby secure complete ruin for their rivals. Hence the present level of taxation. Vanity is a motive of immense potency. Anyone who has much to do with children knows how they are constantly performing some antic, and saying "Look at me." "Look at me" is one of the most fundamental desires of the human heart. It can take innumerable forms, from buffoonery to the pursuit of posthumous fame.

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."

If... it be supposed that another way of measuring time is adopted... enunciation of the law would be... translated into another language... much less simple. So that the definition implicitly adopted by the astronomers may be summed up..: Time should be so defined that the equations of mechanics may be as simple as possible... [i.e.,] there is not one way of measuring time more true... only more convenient.

A good means to discovery is to take away certain parts of a system to find out how the rest behaves.

Only now, as we feel the onslaught behind us, do we begin dimly to apprehend why the animals fought, begot, and died; and behind them the plants; and behind these the huge reserve of inorganic forces. We are moved by pity, gratitude, and esteem for our old comrades-in-arms. They toiled, loved, and died to open a road for our coming. We also toil with the same delight, agony, and exaltation for the sake of Someone Else who with every courageous deed of ours proceeds one step farther. All our struggle once more will have a purpose much greater than we, wherein our toils, our miseries, and our crimes will have become useful and holy.

Every political good carried to the extreme must be productive of evil.

The greatest states have been overthrown by the young and sustained and restored by the old. ... Rashness is the product of the budding-time of youth, prudence of the harvest-time of age.
