The revolution in scientific ideas just mentioned is primarily logical. It is due to recognition that the very method of physical science, with its primary standard units of mass, space, and time, is concerned with measurements of relations of change, not with individuals as such.

One is and remains a slave as long as one is not cured of hoping.

A common monetary standard will be established, with the consent of the various governments, by which industrial transactions will be greatly facilitated. Three spheres made respectively of gold, silver, and platinum, and each weighing fifty grammes, would differ sufficiently in value for the purpose. The sphere should have a small flattened base, and on the great circle parallel to it the Positivist motto would be inscribed. At the pole would be the image of the immortal Charlemagne, the founder of the Western Republic, and round the image his name would be engraved, in its Latin form, Carolus; that name, respected as it is by all nations of Europe alike, would be the common appellation of the universal monetary standard.

The secret of Hegel's dialectic lies ultimately in this alone, that it negates theology through philosophy in order then to negate philosophy through theology. Both the beginning and the end are constituted by theology; philosophy stands in the middle as the negation of the first positedness, but the negation of the negation is again theology. At first everything is overthrown, but then everything is reinstated in its old place, as in Descartes. The Hegelian philosophy is the last grand attempt to restore a lost and defunct Christianity through philosophy, and, of course, as is characteristic of the modern era, by identifying the negation of Christianity with Christianity itself.

A pair of statements may be taken conjunctively or disjunctively; for example, "It lightens and it thunders," is conjunctive, "It lightens or it thunders" is disjunctive. Each such individual act of connecting a pair of statements is a new monad for the mathematician.

Think about the two qualities that a virus, or any sort of parasitic replicator, demands of a friendly medium, the two qualities that make cellular machinery so friendly towards parasitic DNA, and that make computers so friendly towards computer viruses. These qualities are, firstly, a readiness to replicate information accurately, perhaps with some mistakes that are subsequently reproduced accurately; and, secondly, a readiness to obey instructions encoded in the information so replicated.

What defects women have, we must check them for in private, gently by word of mouth, for woman is a frail vessel.

One is still what one is going to cease to be and already what one is going to become. One lives one's death, one dies one's life.

Man is a creation of desire, not a creation of need.

In order to correctly define art, it is necessary, first of all, to cease to consider it as a means to pleasure and consider it as one of the conditions of human life. ...Reflecting on it in this way, we cannot fail to observe that art is one of the means of affective communication between people.

The Anarchists are right in everything; in the negation of the existing order, and in the assertion that, without authority, there could not be worse violence than that of authority under existing conditions. They are mistaken only in thinking that Anarchy can be instituted by a revolution. "To establish Anarchy." "Anarchy will be instituted." But it will be instituted only by there being more and more people who do not require protection from governmental power, and by there being more and more people who will be ashamed of applying this power.

The directing motive, the end and aim of capitalist production, is to extract the greatest possible amount of surplus value, and consequently to exploit labor-power to the greatest possible extent.

I am further of opinion that it would be better for us to have [no laws] at all than to have them in so prodigious numbers as we have.

No period of history has ever been great or ever can be that does not act on some sort of high, idealistic motives, and idealism in our time has been shoved aside, and we are paying the penalty for it.

A man is a god in ruins.

Life is just a notebook with blank pages. Every time we make a mistake, the pages get stained and living in it becomes impossible.

In relation to any act of life, the mind acts as a killjoy.

Perhaps there is one chain [of inference] leading from the mental and the physical to a common source. It is conceivable in the abstract that if mental phenomena derive from the properties of matter at all, these may be identical at some level with nonphysical properties from which physical phenomena also derive. ...If there were such properties, they would be discoverable only by explanatory inference from both mental and physical phenomena. ... There would be properties of matter that were not physical from which the mental properties of organic systems were derived. This could still be called panpsychism.

I once had a conversation with a famous French philosopher who's a friend of mine. And I said to him, "Why the hell do you write so badly? Pourquoi tu écris si mal?" ... And this was Michel Foucault. He was a very smart guy and wrote a lot of very good stuff but in general he just wrote badly. When you heard him give a lecture in Berkeley, it was perfectly clear, just as clear as I am. ... And he said, "Well, in France, it would be regarded as somewhat childish and naive if you wrote clearly. ... In France you've got to have 10% incomprehensible."

It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living.

Do not block the way of inquiry.

Some books are to be tasted, others to be swallowed, and some few to be chewed and digested; that is, some books are to be read only in parts; others to be read, but not curiously; and some few to be read wholly, and with diligence and attention.

[U]nlike positive utilitarianism or so-called preference utilitarianism - neither of which can ever be wholly fulfilled - [negative utilitarianism] seems achievable in full.

To confuse our own constructions and inventions with eternal laws or divine decrees is one of the most fatal delusions of men. 

To the Whigs of the seventeenth century we owe it that we have a House of Commons. To the Whigs of the nineteenth century we owe it that the House of Commons has been purified. The abolition of the slave trade, the abolition of colonial slavery, the extension of popular education, the mitigation of the rigour of the penal code, all, all were effected by that party; and of that party, I repeat, I am a member. I look with pride on all that the Whigs have done for the cause of human freedom and of human happiness. I see them now hard pressed, struggling with difficulties, but still fighting the good fight. At their head I see men who have inherited the spirit and the virtues, as well as the blood, of old champions and martyrs of freedom... While one shred of the old banner is flying, by that banner will I at least be found.

It is clear that the causal nexus is not a nexus at all.

If the thought enunciates an object as a truth, it is only as a challenge to this object's own self-fulfillment.

[W]e hold, that the moral obligation of providing for old age, helpless infancy, and poverty, is far superior to that of supplying the invented wants of courtly extravagance, ambition and intrigue.

I am not bound over to swear allegiance to any master; where the storm drives me I turn in for shelter.

Many city-dwellers have a romanticized conception of the living world. From another perspective, some "conservation biologists" favour e.g. "Pleistocene rewilding". By contrast, I think any truly compassionate person should be horrified at the terrible suffering of Nature "red in tooth and claw". Why not aim for a cruelty-free world instead?

Mediocrity in poets has never been tolerated by either men, or gods, or booksellers.

He is happy, whose circumstances suit his temper; but he is more excellent, who can suit his temper to any circumstances.

Reason not with him, that will deny the principal truths!

The ego involved in responsibility is me and no one else, me with whom one whould have liked to pair up a sister soul, from whom one would have substitution and sacrifice.

You shall have joy, or you shall have power, said God; you shall not have both.

[T]he first philosophers, in investigating the truth and the nature of things, wandered, as if led by ignorance, into a certain... path. Hence, they say that no being is either generated or corrupted, because it is necessary that what is generated should be generated either from being or non-being: but both these are impossible; for neither can being be generated, since it already is; and from nothing, nothing can be generated... And thus... they said that there were not many things, but that being alone had a subsistence. ...the ancient philosophers ...through this ignorance added so much to their want of knowledge, as to fancy that nothing else was generated or had a being; but they subverted all generation.

I cannot say that I am in the slightest degree impressed by your bigness, or your material resources, as such. Size is not grandeur, and territory does not make a nation. The great issue, about which hangs true sublimity, and the terror of overhanging fate, is what are you going to do with all these things?

Reason does not exist for the sake of life, but life for the sake of reason. An existence which does not of itself satisfy reason and solve all her doubts, cannot be the true one.

The professional tends to classify and to specialize, to accept uncritically the ground rules of the environment. The ground rules provided by the mass response of his colleagues serves as a pervasive environment of which he is contentedly unaware.

What has always made the state a hell on earth has been precisely that man has tried to make it heaven.

The state of health is a state of nonsensation, even of nonreality. As soon as we cease to suffer, we cease to exist.

It may be that the public mind of India may expand under our system till it has outgrown that system; that by good government we may educate our subjects into a capacity for better government, that, having become instructed in European knowledge, they may, in some future age, demand European institutions. Whether such a day will ever come I know not. But never will I attempt to avert or to retard it. Whenever it comes, it will be the proudest day in English history.

And in these foure things, Opinion of Ghosts, Ignorance of second causes, Devotion towards what men fear, and Taking of things Casuall for Prognostics, consisteth the Natural seed of Religion; which by reason of the different Fancies, Judgements, and Passions of severall men, hath grown up into ceremonies so different, that those which are used by one man, are for the most part ridiculous to another.

For he must rule as king until God has put all enemies under his feet. And the last enemy, death, is to be brought to nothing.

We do not, however, reckon that trade disadvantageous which consists in the exchange of the hard-ware of England for the wines of France;and yet hard-ware is a very durable commodity, and were it not for this continual exportation, might too be accumulated for ages together, to the incredible augmentation of the pots and pans of the country. But it readily occurs that the number of such utensils is in every country necessarily limited by the use which there is for them;that it would be absurd to have more pots and pans than were necessary for cooking the victuals usually consumed there;and that if the quantity of victuals were to increase, the number of pots and pans would readily increase along with it, apart of the increased quantity of victuals being employed in purchasing them, or in maintaining an additional number of workman whose business it was to make them.

Let great authors have their due, as time, which is the author of authors, be not deprived of his due, which is, further and further to discover truth.

Men go to a fire for entertainment. When I see how eagerly men will run to a fire, whether in warm or in cold weather, by day or by night, dragging an engine at their heels, I'm astonished to perceive how good a purpose the level of excitement is made to serve.

The mask, like the side-show freak, is mainly participatory rather than pictorial in its sensory appeal.

Nobody really thinks who does not abstract from that which is given, who does not relate the facts to the factors which have made them, who does not - in his mind - undo the facts. Abstractness is the very life of thought, the token of its authenticity.
