Ordinary language is totally unsuited for expressing what physics really asserts, since the words of everyday life are not sufficiently abstract. Only mathematics and mathematical logic can say as little as the physicist means to say.

The line that connects the bombing of civilian populations to the mountain removed by strip mining ... to the tortured prisoner seems to run pretty straight. We're living, it seems, in the culmination of a long warfare - warfare against human beings, other creatures and the Earth itself.

It is experience, rather than understanding, that influences behaviour.

Resting on your laurels is as dangerous as resting when you are walking in the snow. You doze off and die in your sleep.

How can one be late to the end of history? A question for today. It is serious because it obliges one to reflect again, as we have been doing since Hegel, on what happens and deserves the name of event, after history; it obliges one to wonder if the end of history is but the end of a certain concept of history.

A pupil and a teacher. The pupil will not let anything be explained to him, for he continually interrupts with doubts, for instance as to the existence of things, the meaning for words, etc. The teacher says "Stop interrupting me and do as I tell you. So far your doubts don't make sense at all."

Never promise more than you can perform.

If one is to take Lulu's twelve-tone chord as the integral totality of complementary harmony, then Berg's allegorical genius proves itself within a historical perspective which makes the brain reel: just as Lulu in the world of total illusion longs for nothing but her murderer and finally finds him in that sound, so does all harmony of unrequited happiness long for its fatal chord as the cipher of fulfillment - twelve-tone music is not to be separated from dissonance. Fatal: because all dynamics come to a standstill within it without finding release. The law of complementary harmony already implies the end of the musical experience of time, as this was heralded in the dissociation of time according to Expressionistic extremes.

Without the collapse of capitalism the expropriation of the capitalist class is impossible.

But for my part (Continues Carneades) what my Indignation at this Un-philosophical way of teaching Principles has now extorted from me, is meant chiefly to excuse my self, if I shall hereafter oppose any Particular Opinion or assertion, that some Follower of Paracelsus or any Eminent Artist may pretend not to be his Masters. For, as I told you long since, I am not Oblig'd to examine private mens writings, (which were a Labour as endless as unprofitable) being only engag'd to examine those Opinions about the Tria Prima, which I find those Chymists I have met with to agree in most: And I Doubt not but my Arguments against their Doctrine will be in great part easily enough applicable ev'n to those private Opinions, which they do not so directly and expresly oppose.

Virtue is reason which has become energy.

The profit of books is according to the sensibility of the reader. The profoundest thought or passion sleeps as in a mine until an equal mind and heart finds and publishes it.

Tears do not burn except in solitude.

It is not, what a lawyer tells me I may do; but what humanity, reason, and justice, tell me I ought to do.

He who is in love is wise and is becoming wiser, sees newly every time he looks at the object beloved, drawing from it with his eyes and his mind those virtues which it possesses.

Although the whole of this life were said to be nothing but a dream and the physical world nothing but a phantasm, I should call this dream or phantasm real enough, if, using reason well, we were never deceived by it.

It is a familiar and significant saying that a problem well-put is half-solved.

Miniaturization doesn't actually make sense unless you miniaturize the very atoms of which matter is composed. Otherwise a tiny brain in a man the size of an insect, composed of normal atoms, is composed of too few atoms for the miniaturized man to be any more intelligent than the ant. Also, miniaturizing atoms is impossible according to the rules of quantum mechanics.

Fear is the antidote to boredom: the remedy must be stronger than the disease.

When I play with my cat, who knows whether I do not make her more sport than she makes me?

The political program of nation building in countries like Afghanistan and Iraq is one central example of the productive project of biopower and war. Nothing could be more postmodernist and antiessentialist than this notion of nation building.

Put in a nut-shell, my thesis amounts to this. The repeated attempts made by Rudolf Carnap to show that the demarcation between science and metaphysics coincides with that between sense and nonsense have failed. The reason is that the positivistic concept of 'meaning' or 'sense' (or of verifiability, or of inductive confirmability, etc.) is inappropriate for achieving this demarcation - simply because metaphysics need not be meaningless even though it is not science. In all its variations demarcation by meaninglessness has tended to be at the same time too narrow and too wide: as against all intentions and all claims, it has tended to exclude scientific theories as meaningless, while failing to exclude even that part of metaphysics which is known as 'rational theology'.

I hardly know an intellectual man, even, who is so broad and truly liberal that you can think aloud in his society. Most with whom you endeavor to talk soon come to a stand against some institution in which they appear to hold stock, - that is, some particular, not universal, way of viewing things.

On the whole, a man who denies the existence of the effects arranged according to the causes in the question of arts, or whose wisdom cannot understand it, then he has no knowledge of the art of its Maker.

Almost as soon as I began to study philosophy, I was impressed by the way in which philosophical problems appeared, disappeared, or changed shape, as a result of new assumptions or vocabularies.

The one intelligible theory of the universe is that of objective idealism, that matter is effete mind, inveterate habits becoming physical laws. But before this can be accepted it must show itself capable of explaining the tridimensionality of space, the laws of motion, and the general characteristics of the universe, with mathematical clearness and precision ; for no less should be demanded of every Philosophy.

What! all of us, Christians, not only profess to love one another, but do actually live one common life; we whose social existence beats with one common pulse-we aid one another, learn from one another, draw ever closer to one another to our mutual happiness, and find in this closeness the whole meaning of life!-and to-morrow some crazy ruler will say some stupidity, and another will answer in the same spirit, and then I must go expose myself to being murdered, and murder men-who have done me no harm-and more than that, whom I love. And this is not a remote contingency, but the very thing we are all preparing for, which is not only probable, but an inevitable certainty.

Martyrs create faith, faith does not create martyrs.

Christianity is most admirably adapted to the training of slaves, to the perpetuation of a slave society; in short, to the very conditions confronting us to-day.... The rulers of the earth have realized long ago what potent poison inheres in the Christian religion. That is the reason they foster it; that is why they leave nothing undone to instill it into the blood of the people. They know only too well that the subtleness of the Christian teachings is a more powerful protection against rebellion and discontent than the club or the gun.

Being Gentlemen and very far from the litigious humour of loving to wrangle about words or terms or notions as empty; they had before his coming in, readily agreed promiscuously to use when they pleased Elements and Principles as terms equivalent: and to understand both by the one and the other, those primitive and simple bodies of which the mixt ones are said to be composed, and into which they are ultimately resolved.

I will now tell you who are assembled here the wise sayings of Mazda, the praises of Ahura and the hymns of the Good Spirit, the sublime truth which I see rising out of these flames. You shall therefore harken to the Soul of Nature. Contemplate the beams of fire with a most pious mind. Every one, both men and women, ought to-day to choose his creed. Ye offspring of renowned ancestors, awake to agree with us. So preached Zoroaster, the proph of the Parsis, in one of his earliest sermons nearly 3,500 years ago.

If man reflects on the changes and transformations which follow one another like wave after wave and their rapidity, he will despise everything which is perishable.

...what I look to with seriousness is the Phalanx of Party which exists in the body of the dissenters, who are, at the very least, nine tenths of them entirely devoted, some with greater some with less zeal, to the principles of the French Revolution.

An honest man nearly always thinks justly.

The issue over there being classes seems more a question of convenient conceptual scheme; the issue over there being centaurs, or brick houses on Elm Street, seems more a question of fact. But I have been urging that this difference is only one of degree, and that it turns upon our vaguely pragmatic inclination to adjust one strand of the fabric of science rather than another in accommodating some particular recalcitrant experience. Conservatism figures in such choices, and so does the quest for simplicity.

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

Mercy often means giving death, not life.

To fear love is to fear life, and those who fear life are already three parts dead.

Christ speaks of two debtors, one of whom owed much and the other little, and who both found forgiveness. He asks: Which of these two ought to love more? The answer: The one who has forgiven much. When you love much, you are forgiven much-and when you are forgiven much, you love much. See here the blessed recurrence of salvation in love!

This avidity alone, of acquiring goods and possessions for ourselves and our nearest friends, is insatiable, perpetual, universal, and directly destructive of society.

Moderation is the spirit of castrated narrow-mindedness.

It is the highest impertinence and presumption, therefore, in kings and ministers, to pretend to watch over the economy of private people, and to restrain their expence, either by sumptuary laws, or by prohibiting the importation of foreign luxuries. They are themselves always, and without any exception, the greatest spendthrifts in the society. Let them look well after their own expence, and they may safely trust private people with theirs. If their own extravagance does not ruin the state, that of their subjects never will.

My entire soul is a cry, and all my work the commentary on that cry.

Ideals are imaginative understanding of that which is desirable in that which is possible.

Those that will combat use and custom by the strict rules of grammar do but jest.

One unscrupulous distortion of the truth tends to beget other and opposite distortions.

The mob has always behaved in this way-eagerly open to bribes that cannot be honorably accepted, and dissolutely callous to degradation and insult that cannot be honorably endured.

The mind that puts everything in question, reaches, after a thousand interrogations, an almost total inertia, a situation which the inert, in fact, knows from the start, by instinct. For what is inertia but a congenital perplexity?
