We suppose, it would seem, that concepts grow in the individual mind like leaves on a tree, and we think to discover their nature by studying their growth; we seek to define them psychologically, in terms of the human mind. But this account makes everything subjective, and if we follow it through to the end, does away with truth. What is known as the history of concepts is really a history either of our knowledge of concepts or of the meanings of words.

Actual aristocracy cannot be abolished by any law: all the law can do is decree how it is to be imparted and who is to acquire it.

You know how much I admire Che Guevara. In fact, I believe that the man was not only an intellectual but also the most complete human being of our age: as a fighter and as a man, as a theoretician who was able to further the cause of revolution by drawing his theories from his personal experience in battle.

Now, that we do not really know of what sort each thing is, or is not, has often been shown.

Cleanness of body was ever deemed to proceed from a due reverence to God.

It does not matter whether the right to govern is hereditary or obtained with the consent of the governed. A State is absolute in the sense which I have in mind when it claims the right to a monopoly of all the force within the community, to make war, to make peace, to conscript life, to tax, to establish and dis-establish property, to define crime, to punish disobedience, to control education, to supervise the family, to regulate personal habits, and to censor opinions. The modern State claims all of these powers, and, in the matter of theory, there is no real difference in the size of the claim between communists, fascists, and democrats.

Prove your words by your deeds.

Delight at having understood a very abstract and obscure system leads most people to believe in the truth of what it demonstrates.

The point is that philosophy is seen to have come full circle, and to have exhausted itself.

Sexual activity is driven by the same aims and motives as reading poetry or listening to music: to escape the limitations imposed by the need for particularity in the consciousness.

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.

In books lies the soul of the whole Past Time; the articulate audible voice of the Past, when the body and material substance of it has altogether vanished like a dream.

The fleshless diet contributes to health and to a suitable endurance of hard work in philosophy.

The States should be urged to concede to the General Government, with a saving of chartered rights, the exclusive power of establishing banks of discount for paper.

As soon as men live entirely in accord with the law of love natural to their hearts and now revealed to them, which excludes all resistance by violence, and therefore hold aloof from all participation in violence - as soon as this happens, not only will hundreds be unable to enslave millions, but not even millions will be able to enslave a single individual.

I have lived and slept in the same bed with English countesses and Prussian farm women... no woman has excited passions among women more than I have.

There is no more mistaken path to happiness than worldliness, revelry, high life.

Have we really the right to speak of the cause of a phenomenon?

When common words are appropriated as technical terms, their meaning may be modified, and must be rigorously fixed.

Think about the strangeness of today's situation. Thirty, forty years ago, we were still debating about what the future will be: communist, fascist, capitalist, whatever. Today, nobody even debates these issues. We all silently accept global capitalism is here to stay. On the other hand, we are obsessed with cosmic catastrophes: the whole life on earth disintegrating, because of some virus, because of an asteroid hitting the earth, and so on. So the paradox is, that it's much easier to imagine the end of all life on earth than a much more modest radical change in capitalism.

The basis of science is the empirical method, which uses the senses to build up a picture of the world; but science tells us that our senses have evolved to help us get by, not to show us the world as it is. Science is only a systematic examination of our impressions, and in the end all each of us has left are our own sensations ... The end-result of the empirical method, then, is that each individual is left alone with their own experiences. We can escape this solitude, Balfour suggested, only if we accept that there is a divine mind.

The equal right of all men to the use of land is as clear as their equal right to breathe the air - it is a right proclaimed by the fact of their existence. For we cannot suppose that some men have a right to be in this world, and others no right.

And because the condition of Man, (as hath been declared in the precedent Chapter) is a condition of Warre of every one against everyone; in which case every one is governed by his own Reason; and there is nothing he can make use of, that may not be a help unto him, in preserving his life against his enemyes; It followeth, that in such a condition, every man has a Right to every thing; even to one anothers body.

As you say of yourself, I too am an Epicurian. I consider the genuine (not the imputed) doctrines of Epicurus as containing everything rational in moral philosophy which Greece and Rome have left us.

Is it always permissible to speak of the extension of a concept, of a class? And if not, how do we recognize the exceptional cases? Can we always infer from the extension of one concept's coinciding with that of a second, that every object which falls under the first concept also falls under the second?

Do you think that God will punish them for not practicing a religion which he did not reveal to them?

We are living in the most destructive and, hence, the most stupid period of the history of our species.

Names and attributes must be accommodated to the essence of things, and not the essence to the names, since things come first and names afterwards.

How can this cosmic religious experience be communicated from man to man, if it cannot lead to a definite conception of God or to a theology? It seems to me that the most important function of art and of science is to arouse and keep alive this feeling in those who are receptive.

Certain forms of sex which do not lead to children are at present punished by the criminal law: this is purely superstitious, since the matter is one which affects no one except the parties directly concerned... The peculiar importance attached, at present, to adultery is quite irrational... Moral rules ought not to be such as to make instinctive happiness impossible.

Life is too short to occupy oneself with the slaying of the slain more than once. One of a series of exchanges when Richard Owen repeated generally repudiated claims about the Gorilla brain in a Royal Institution lecture.

When it is a question of money, everybody is of the same religion.

Physicists and philosophers stick stubbornly to the principles of a mechanistic interpretation of the world after physics has, in its factual structure, already outgrown the latter. They have the same excuse as the inhabitant of the mainland who for the first time travels on the open sea: he will desperately try to stay in sight of the vanishing coast line, as long as there is no other coast in sight, towards which he steers.

Since a great part of those Learned Men, especially Physicians who have discerned the defects of the vulgar Philosophy, but are not yet come to understand and relish the Corpuscularian, have slid into the Doctrine of the Chymists; and since the Spagyrists are wont to pretend to make out all the Qualities of bodies from the Predominancy of some one of their three Hypostatical Principles, I suppose it may both keep my opinion from appearing too presumptuous, and (which is far more considerable) may make way for the fairer Reception of the Mechanical Hypothesis about Qualities, if I here intimate (though but briefly and in general) some of those defects, that I have observed in Chymists Explications of Qualities.

Some decent regulated pre-eminence, some preference (not exclusive appropriation) given to birth, is neither unnatural, nor unjust, nor impolitic.

If there is one realm in which it is essential to be sublime, it is in wickedness. You spit on a petty thief, but you can't deny a kind of respect for the great criminal.

Avoid shame, but do not seek glory: nothing so expensive as glory.

But greatly his most important culture he had gathered - and this, too, by his own endeavors - from the better part of the district, the religious men; to whom, as to the most excellent, his own nature gradually attached and attracted him. He was religious with the consent of his whole faculties. Without religion he would have been nothing.

Maman used to say that you can always find something to be happy about.

My appetite comes to me while eating.

For a consistent naturalist science can only be a refinement of animal exploration, a practice humans have devised for finding their way in the bit of the universe in which they have so far survived. Instead of thinking of science as a law-seeking activity, we can think of it as a tool humans use to cope with a world they will never understand.

But as to our country and our race, as long as the well compacted structure of our church and state, the sanctuary, the holy of holies of that ancient law, defended by reverence, defended by power, a fortress at once and a temple, shall stand inviolate on the brow of the British Sion-as long as the British Monarchy, not more limited than fenced by the orders of the State, shall, like the proud Keep of Windsor, rising in the majesty of proportion, and girt with the double belt of its kindred and coeval towers, as long as this awful structure shall oversee and guard the subjected land-so long as the mounds and dykes of the low, fat, Bedford level will have nothing to fear from all the pickaxes of all the levellers of France.

Nothing that was worthy in the past departs; no truth or goodness realized by man ever dies, or can die.

The wealth required by nature is limited and is easy to procure; but the wealth required by vain ideals extends to infinity.

Hear the verbal protestations of all men: Nothing so certain as their religious tenets. Examine their lives: You will scarcely think that they repose the smallest confidence in them. The greatest and truest zeal gives us no security against hypocrisy: The most open impiety is attended with a secret dread and compunction. No theological absurdities so glaring that they have not, sometimes, been embraced by men of the greatest and most cultivated understanding. No religious precepts so rigorous that they have not been adopted by the most voluptuous and most abandoned of men.

Everybody knows that the same sum of money is of much greater value to a poor man that to a rich one. Give £10 a year to the man who has but £10 a year, you double his income, and you nearly double his enjoyments. Add £10 more, you do not add to his enjoyments so much as you did by the first £10. The third £10 is less valuable than the second, and the fourth less valuable than the third. To the possessor of £1,000 a year the addition of £10 would be scarcely perceptible; to the possessor of £10,000 it would not be worth slooping for.The richer a man is the less he is benefited by any further addition to his income. The man of £4,000 a year has four times the income of the man who has but £1,000; but does anybody suppose that he has four times the happiness?

I never lose an opportunity of urging a practical beginning, however small, for it is wonderful how often in such matters the mustard-seed germinates and roots itself.

Man, in wearing himself out his whole life long by saying: What is that! and what is that called! and what does that mean! is a big spectacle to himself if he wants to open his eyes. All his natural powers tending towards the truth, he never ceases looking for true names; he senses a language prior to that of Babel, and even of Eden.
