The basis of all Natural Systems of Classification is the Idea of Natural Affinity. The Principle which this Idea involves is this:-Natural arrangements, obtained from 'different' sets of characters, must 'coincide' with each other.

The major and almost only theme of all my work is the struggle of man with "God": the unyielding, inextinguishable struggle of the naked worm called "man" against the terrifying power and darkness of the forces within him and around him.

As one digs deeper into the national character of the Americans, one sees that they have sought the value of everything in this world only in the answer to this single question: how much money will it bring in?

The ability to speak exactly is intimately related to the ability to know exactly.

Privacy invasion is now one of biggest knowledge industries.

When equality is treated not as a medicine or a safety-gadget, but as an ideal, we begin to breed that stunted and envious sort of mind which hates all superiority. That mind is the special disease of democracy, as cruelty and servility are the special diseases of privileged societies. It will kill us all if it grows unchecked. The man who cannot conceive a joyful and loyal obedience on the one hand, nor an unembarrassed and noble acceptance of that obedience on the other - the man who has never even wanted to kneel or to bow - is a prosaic barbarian. But it would be wicked folly to restore these old inequalities on the legal or external plane. Their proper place is elsewhere.

Men by their constitutions are naturally divided into two parties: 1. Those who fear and distrust the people, and wish to draw all powers from them into the hands of the higher classes. 2. Those who identify themselves with the people, have confidence in them, cherish and consider them as the most honest and safe, although not the most wise depositary of the public interests. In every country these two parties exist, and in every one where they are free to think, speak, and write, they will declare themselves. Call them, therefore, liberals and serviles, Jacobins and Ultras, whigs and tories, republicans and federalists, aristocrats and democrats, or by whatever name you please, they are the same parties still and pursue the same object. The last appellation of aristocrats and democrats is the true one expressing the essence of all.

The child shows its individual tendencies in its plays, in its questions, in its association with people and things. But it has to struggle with everlasting external interference in its world of thought and emotion. It must not express itself in harmony with its nature, with its growing personality. It must become a thing, an object. Its questions are met with narrow, conventional, ridiculous replies, mostly based on falsehoods; and, when, with large, wondering, innocent eyes, it wishes to behold the wonders of the world, those about it quickly lock the windows and doors, and keep the delicate human plant in a hothouse atmosphere, where it can neither breathe nor grow freely.

He has begun by supposing that light has a constant velocity... the same in all directions. This... could never be verified directly by experiment... The postulate... resembling the principle of sufficient reason... furnishes us with a new rule for the investigation of simultaneity.

In a certain sense, everything is everywhere at all times. For every location involves an aspect of itself in every other location. Thus every spatio-temporal standpoint mirrors the world.

The trouble with Eichmann was precisely that so many were like him, and that the many were neither perverted nor sadistic, that they were, and still are, terribly and terrifyingly normal. From the viewpoint of our legal institutions and of our moral standards of judgment, this normality was much more terrifying than all the atrocities put together, for it implied - as had been said at Nuremberg over and over again by the defendants and their counsels - that this new type of criminal, who is in actual fact hostis generis humani, commits his crimes under circumstances that make it well-nigh impossible for him to know or to feel that he is doing wrong.

I write in a hurry, because the little one, who has been sleeping a long time, begins to call for me. Poor thing! when I am sad, I lament that all my affections grow on me, till they become too strong for my peace, though they all afford me snatches of exquisite enjoyment.

If you wish to extinguish that enthusiasm, which inspires great thoughts, and impels to noble enterprises;-if you wish to render men's hearts cold, and unfeeling; and to substitute egotism in the room of generous, and ardent, patriotism,-if you wish to do this, only take away from the people their faith, and make them philosophers.

Our mass media have little difficulty in selling particular interests as those of all sensible men. The political needs of society become individual needs and aspirations, their satisfaction promotes business and the commonweal, and the whole appeals to be the very embodiment of Reason.

Do we write books so that they shall merely be read? Don't we also write them for employment in the household? For one that is read from start to finish, thousands are leafed through, other thousands lie motionless, others are jammed against mouseholes, thrown at rats, others are stood on, sat on, drummed on, have gingerbread baked on them or are used to light pipes.

Even if a civil society were to be dissolved by the consent of all its members (e.g., if a people inhabiting an island decided to separate and disperse throughout the world), the last murderer remaining in prison would first have to be executed, so that each has done to him what his deeds deserve and blood guilt does not cling to the people for not having insisted upon this punishment; for otherwise the people can be regarded as collaborators in his public violation of justice.

I want to make one thing absolutely clear. I am not a Zen Buddhist, I am not advocating Zen Buddhism, I am not trying to convert anyone to it. I have nothing to sell. I'm an entertainer. That is to say, in the same sense, that when you go to a concert and you listen to someone play Mozart, he has nothing to sell except the sound of the music. He doesn't want to convert you to anything. He doesn't want you to join an organization in favor of Mozart's music as opposed to, say, Beethoven's. And I approach you in the same spirit as a musician with his piano or a violinist with his violin. I just want you to enjoy a point of view that I enjoy.

But such is the nature of the human mind, that it always lays hold on every mind that approaches it; and as it is wonderfully fortified by an unanimity of sentiments, so is it shocked and disturbed by any contrariety. Hence the eagerness, which most people discover in a dispute; and hence their impatience of opposition, even in the most speculative and indifferent opinions.

It has been said a thousand times and in a thousand books that ancestor-worship is for the most part the source of primitive religions, and it may be strictly said that what most distinguishes man from the other animals is that, in one form or another, he guards his dead and does not give them over to the neglect of teeming mother earth; he is an animal that guards its dead.

Doubtless, it shews the wisdom of God, to have so fram'd things at first, that there can seldom or never need any extraordinary interposition of his power; or the employing from, time to time, an intelligent overseer, to regulate, assist, and control the motions of matter.

Every poet and musician and artist, but for Grace, is drawn away from love of the thing he tells to love of the telling till, down in Deep Hell, they cannot be interested in God at all but only in what they say about Him.

What song the Syrens sang, or what name Achilles assumed when he hid himself among women, though puzzling questions, are not beyond all conjecture.

We are not arrogant, not hubristic, to celebrate the sheer bulk and detail of what we know through science. We are simply telling the honest and irrefutable truth. Also honest is the frank admission of how much we don't yet know - how much more work remains to be done. That is the very antithesis of hubristic arrogance. Science combines a massive contribution, in volume and detail, of what we do know with humility in proclaiming what we don't. Religion, by embarrassing contrast, has contributed literally zero to what we know, combined with huge hubristic confidence in the alleged facts it has simply made up.

Under the pressure of the cares and sorrows of our mortal condition, men have at all times, and in all countries, called in some physical aid to their moral consolations - wine, beer, opium, brandy, or tobacco.

There must be a seed of every good thing in the character of men, otherwise no one can bring it out. Lacking that, analogous motives, honor, etc., are substituted. Parents are in the habit of looking out for the inclinations, for the talents and dexterity, perhaps for the disposition of their children, and not at all for their heart or character.

Women are the most charitable creatures, and the most troublesome. He who shuns women passes up the trouble, but also the benefits. He who puts up with them gains the benefits, but also the trouble. As the saying goes, there's no honey without bees.

You cannot conduct war with equals; you cannot have militarism with free born men; you must have slaves, automatons, machines, obedient disciplined creatures, who will move, act, shoot and kill at the command of their superiors. That is preparedness, and nothing else.

Literature is idiosyncratic arrangements in horizontal lines in only twenty-six symbols, ten arabic numbers, and about eight punctuation marks.

The soul is the prison of the body.

A created thing is never invented and it is never true: it is always and ever itself.

Whensoever hostile aggressions...require a resort to war, we must meet our duty and convince the world that we are just friends and brave enemies.

You do not ask what is the value, or what is the use, of this feeling. Of what use is the universe? What is the practical application of a million galaxies? Yet just because it has no use, it has a use-which may sound like a paradox, but is not. What, for instance, is the use of playing music? If you play to make money, to outdo some other artist, to be a person of culture, or to improve your mind, you are not really playing-for your mind is not on the music. You don't swing. When you come to think of it, playing or listening to music is a pure luxury, an addiction, a waste of valuable time and money for nothing more than making elaborate patterns of sound.

The self-discipline of the Social Democracy is not merely the replacement of the authority of bourgeois rulers with the authority of a socialist central committee. The working class will acquire the sense of the new discipline, the freely assumed self-discipline of the Social Democracy, not as a result of the discipline imposed on it by the capitalist state, but by extirpating, to the last root, its old habits of obedience and servility.

I am showing my pupils details of an immense landscape which they cannot possibly know their way around.

Happy the people whose annals are blank in history books!

We hardly know any instance of the strength and weakness of human nature so striking, and so grotesque, as the character of this haughty, vigilant, resolute, sagacious blue-stocking, half Mithridates and half Trissotin, bearing up against a world in arms, with an ounce of poison in one pocket and a quire of bad verses in the other.

A person might fairly doubt also what in the world they mean by the absolute - this that or the other, since, as they would themselves allow, the account of the humanity is one and the same in the absolute man, and in any individual man: for so far as the individual and the absolute man are both man, they will not differ at all: and if so, then the essential good and any particular good will not differ, in so far as both are good. Nor will it do to say that the eternity of the absolute good makes it to be more good; for a white thing which has lasted white ever so long, is no whiter than that which only lasts for a day.

Happiest are the people who give most happiness to others.

If I seem happy to you . . . You could never say anything that would please me more. For men are made for happiness, and anyone who is completely happy has a right to say to himself, 'I am doing God's will on earth.' All the righteous, all the saints, all the holy martyrs were happy.

Look round the world: contemplate the whole and every part of it: You will find it to be nothing but one great machine, subdivided into an infinite number of lesser machines, which again admit of subdivisions, to a degree beyond what human senses and faculties can trace and explain. All these various machines, and even their most minute parts, are adjusted to each other with an accuracy, which ravishes into admiration all men, who have ever contemplated them. The curious adapting of means to ends, throughout all nature, resembles exactly, though it much exceeds, the productions of human contrivance; of human design, thought, wisdom, and intelligence.

All my life, I have lived with the feeling that I have been kept from my true place. If the expression "metaphysical exile" had no meaning, my existence alone would afford it one.

One might naively suppose that a negative utilitarian would welcome human extinction. But only (trans)humans - or our potential superintelligent successors - are technically capable of phasing out the cruelties of the rest of the living world on Earth. And only (trans)humans - or rather our potential superintelligent successors - are technically capable of assuming stewardship of our entire Hubble volume.

All science must start with some assumptions as to the ultimate analysis of the facts with which it deals. These assumptions are justified partly by their adherence to the types of occurrence of which we are directly conscious, and partly by their success in representing the observed facts with a certain generality, devoid of ad hoc suppositions.

Farewell to the monsters, farewell to the saints. Farewell to pride. All that is left is men.

I am old, but I certainly have not that sign of old age, extolling the past at the expense of the present.

You don't have to be a scientist - you don't have to play the Bunsen burner - in order to understand enough science to overtake your imagined need and fill that fancied gap. Science needs to be released from the lab into the culture.
