There were two brothers called Both and Either; perceiving Either was a good, understanding, busy fellow, and Both a silly fellow and good for little, Philip said, "Either is both, and Both is neither."

Remember Bostrom's definition of existential risk, which refers to the annihilation not of human beings, but of "Earth-originating intelligent life." The replacement of our species by some other form of conscious intelligent life is not in itself, impartially considered, catastrophic. Even if the intelligent machines kill all existing humans, that would be...a very small part of the loss of value that Parfit and Bostrom believe would be brought about by the extinction of Earth-originating intelligent life. The risk posed by the development of AI, therefore, is not so much whether it is friendly to us, but whether it is friendly to the idea of promoting wellbeing in general, for all sentient beings it encounters, itself included.

We do not obtain the most precious gifts by going in search of them but by waiting for them. Man cannot discover them by his own powers, and if he sets out to seek for them he will find in their place counterfeits of which he will be unable to discern falsity.

Gratitude looks to the past and love to the present; fear, avarice, lust, and ambition look ahead.

Having destroyed the social power of the nobility and the guildmasters, the bourgeois also destroyed their political power. Having raised itself to the actual position of first class in society, it proclaims itself to be also the dominant political class. This it does through the introduction of the representative system which rests on bourgeois equality before the law and the recognition of free competition, and in European countries takes the form of constitutional monarchy. In these constitutional monarchies, only those who possess a certain capital are voters - that is to say, only members of the bourgeoisie. These bourgeois voters choose the deputies, and these bourgeois deputies, by using their right to refuse to vote taxes, choose a bourgeois government.

I have often regretted my speech, never my silence.

All his life he [the American] jumps into the train after it has started and jumps out before it has stopped; and he never once gets left behind, or breaks a leg.

Intellectuals cannot be good revolutionaries; they are just good enough to be assassins.

Bourgeois society is ruled by equivalence. It makes the dissimilar comparable by reducing it to abstract quantities. To the Enlightenment, that which does not reduce to numbers, and ultimately to the one, becomes illusion.

If an action ... involves little profit but much righteousness, do it.

American life is a powerful solvent. As it stamps the immigrant, almost before he can speak English, with an unmistakable muscular tension, cheery self-confidence and habitual challenge in the voice and eyes, so it seems to neutralize every intellectual element, however tough and alien it may be, and to fuse it in the native good-will, complacency, thoughtlessness, and optimism.

If there is to be any philosophy at all, this contradiction must be resolved - and the solution of this problem, or answer to the question: how can we think both of Presentations as conforming to objects, and objects as conforming to presentations? is, not the first, but the highest task of transcendental philosophy.

In America a woman loses her independence for ever in the bonds of matrimony. While there is less constraint on girls there than anywhere else, a wife submits to stricter obligations. For the former, her father's house is a home of freedom and pleasure; for the latter, her husband's is almost a cloister.

To give the monopoly of the home-market to the produce of domestic industry, in any particular art or manufacture, is in some measure to direct private people in what manner they ought to employ their capitals, and must, in almost all cases, be either a useless or a hurtful regulation.

Death cannot explain itself. The earnestness consists precisely in this, that the observer must explain it to himself.

The seeing eye! It is this that discloses the inner harmony of things; what Nature meant, what musical idea Nature has wrapped up in these often rough embodiments. Something she did mean. To the seeing eye that something were discernible. Are they base, miserable things? You can laugh over them, you can weep over them; you can in some way or other genially relate yourself to them; - you can, at lowest, hold your peace about them, turn away your own and others' face from them, till the hour come for practically exterminating and extinguishing them!

We can't form our children on our own concepts; we must take them and love them as God gives them to us.

The skepticism which fails to contribute to the ruin of our health is merely an intellectual exercise.

For the Lawes of Nature (as Justice, Equity, Modesty, Mercy, and (in summe)doing to others, as wee would be done to,) of themselves, without the terrour of some Power, to cause them to be observed, are contrary to our naturall Passions, that carry us to Partiality, Pride, Revenge, and the like. And Covenants, without the Sword, are but Words, and of no strength to secure a man at all.

In the same year in which I began Latin, I made my first commencement in the Greek poet with the Iliad. After I had made some progress in this, my father put Pope's translation into my hands. It was the first English verse I had cared to read, and it became one of the books in which for many years I most delighted: I think I must have read it from twenty to thirty times through. I should not have thought it worth while to mention a taste apparently so natural to boyhood, if I had not, as I think, observed that the keen enjoyment of this brilliant specimen of narrative and versification is not so universal with boys, as I should have expected both à priori and from my individual experience.

People ... become so preoccupied with the means by which an end is achieved, as eventually to mistake it for the end. Just as money, which is a means of satisfying wants, comes to be regarded by a miser as the sole thing to be worked for, leaving the wants unsatisfied; so the conduct men have found preferable because most conducive to happiness, has come to be thought of as intrinsically preferable: not only to be made a proximate end (which it should be), but to be made an ultimate end, to the exclusion of the true ultimate end.

Everyone explains that discussions about Socialism are exceedingly obscure; this obscurity is due, to a large extent, to the fact that contemporary socialists use a terminology which no longer corresponds to their ideas.

In places where men are used to differences they inevitably become tolerant.

Why dost thou not retire like a guest sated with the banquet of life, and with calm mind embrace, thou fool, a rest that knows no care?

All men by nature desire to know. An indication of this is the delight we take in our senses; for even apart from their usefulness they are loved for themselves; and above all others the sense of sight. For not only with a view to action, but even when we are not going to do anything, we prefer sight to almost everything else. The reason is that this, most of all the senses, makes us know and brings to light many differences between things.

If any man will come after me, let him deny himself, and take up his cross, and follow me. For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it. For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul? For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works. Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.

The need to devour oneself absolves one of the need to believe.

Needs must it be hard, since it is so seldom found. How would it be possible, if salvation were ready to our hand, and could without great labour be found, that it should be by almost all men neglected? But all things excellent are as difficult as they are rare.

In ignoring the important fundamental contribution of the followers of Marx, and by insisting exclusively on the phenomenon of superficial adaptation and variation, Sorel passed in silence over all that was healthy, live and fruitful in the Marxist doctrine.

Love may forgive all infirmities and love still in spite of them: but Love cannot cease to will their removal.

Creation is in fact a fault, man's famous sin thereby appearing as a minor version of a much graver one. What are we guilty of, except of having followed, more or less slavishly, the Creator's example? Easy to recognize in ourselves the fatality which was His: not for nothing have we issued from the hands of a wicked and woebegone god, a god accursed.

It is necessary to have regard to the person whom we wish to persuade, of whom we must know the mind and the heart, what principles he acknowledges, what things he loves; and then observe in the thing in question what affinity it has with the acknowledged principles, or with the objects so delightful by the pleasure which they give him.

In Nietzsche's view nihilism is not a Weltanschauung that occurs at some time and place or another; it is rather the basic character of what happens in Occidental history.

Reason, if consulted with, would advise, that their children's time should be spent in acquiring what might be useful to them when they come to be men, rather than to have their heads stuff'd with a deal of trash, a great part whereof they usually never do ('tis certain they never need to) think on again as long as they live: and so much of it as does stick by them they are only the worse for.

Thus Mr. Sale informs me, the old Arab Tribes would gather in liveliest gaudeamus, and sing, and kindle bonfires, and wreathe crowns of honour, and solemnly thank the gods that, in their Tribe too, a Poet had shewn himself. As indeed they well might; for what usefuller, I say not nobler and heavenlier thing could the gods, doing their very kindest, send to any Tribe or Nation, in any time or circumstances?

The science which has to do with nature clearly concerns itself for the most part with bodies and magnitudes and their properties and movements, but also with the principles of this sort of substance, as many as they may be.

The Age that admires talk so much can have little discernment for inarticulate work, or for anything that is deep and genuine. Nobody, or hardly anybody, having in himself an earnest sense for truth, how can anybody recognize an inarticulate Veracity, or Nature-fact of any kind; a Human Doer especially, who is the most complex, profound, and inarticulate of all Nature's Facts? Nobody can recognize him: till once he is patented, get some public stamp of authenticity, and has been articulately proclaimed, and asserted to be a Doer. To the worshipper of talk, such a one is a sealed book. An excellent human soul, direct from Heaven,-how shall any excellence of man become recognizable to this unfortunate? Not except by announcing and placarding itself as excellent,-which, I reckon, it above other things will probably be in no great haste to do.

Interface, of the resonant interval as 'where the action is', whether chemical, psychic or social, involves touch.

As for the commercial business, I can no longer make head or tail of it. At one moment crisis seems imminent and the City prostrated, the next everything is set fair. I know that none of this will have any impact on the catastrophe.

It is forbidden to kill; therefore all murderers are punished unless they kill in large numbers and to the sound of trumpets.

Children are all foreigners.

All metaphysical theories are inconclusively vulnerable to positivist attack.

I am convinced that we have a degree of delight, and that no small one, in the real misfortunes and pains of others.

How easy it is to repel and to wipe away every impression which is troublesome or unsuitable, and immediately to be in all tranquility. To shrug it all off and wipe it clean--every annoyance and distraction--and reach utter stillness. Child's play.

Stupidity is much the same all the world over. A stupid person's notions and feelings may confidently be inferred from those which prevail in the circle by which the person is surrounded. Not so with those whose opinions and feelings are an emanation from their own nature and faculties.

The ancients, even though they believed in destiny, believed primarily in nature, in which they participated wholeheartedly. To rebel against nature amounted to rebelling against oneself.

The cultural atmosphere of Russia in those years had an adolescent quality, common to all periods of revolution: the belief that life is just beginning, that the future is unlimited, and that mankind is no longer bound by the shackles of history.

A Dialogue between two Infants in the womb concerning the state of this world, might handsomely illustrate our ignorance of the next, whereof methinks we yet discourse in Plato's Den, and are but Embryon Philosophers.

Marxism has been the greatest fantasy of our century. It was a dream offering the prospect of a society of perfect unity, in which all human aspirations would be fulfilled and all values reconciled.
