My lectures are published and not published; they will be intelligible to those who heard them, and to none beside.

No position is so false as having understood and still remaining alive.

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.

Mankind was never so happily inspired as when it made a cathedral.

Why, what is weeping and sighing? A judgement. What is misfortune? A judgement. What are strife, disagreement, fault-finding, accusing, impiety, foolishness? They are all judgements.

Talent works for money and fame; the motive which moves genius to productivity is, on the other hand, less easy to determine. It isn't money, for genius seldom gets any. It isn't fame: fame is too uncertain and, more closely considered, of too little worth. Nor is it strictly for its own pleasure, for the great exertion involved almost outweighs the pleasure. It is rather an instinct of a unique sort by virtue of which the individual possessed of genius is impelled to express what he has seen and felt in enduring works without being conscious of any further motivation. It takes place, by and large, with the same sort of necessity as a tree brings forth fruit, and demands of the world no more than a soil on which the individual can flourish.

I can calculate the motions of erratic bodies, but not the madness of a multitude.

There is no one whose death I have not longed for, at one moment or another.

Like a plague, the mad spirit is sweeping the country, infesting the clearest heads and staunchest hearts with the deathly germ of militarism.

Nature is an Æolian Harp, a musical instrument; whose tones again are keys to higher strings in us.

We are on a mission: we are called to the cultivation of the earth.

Long discourses, and philosophical readings, at best, amaze and confound, but do not instruct children. When I say, therefore, that they must be treated as rational creatures, I mean that you must make them sensible, by the mildness of your carriage, and in the composure even in the correction of them, that what you do is reasonable in you, and useful and necessary for them; and that it is not out of caprichio, passion or fancy, that you command or forbid them any thing.

For the inquisition of Final Causes is barren, and like a virgin consecrated to God produces nothing.

When people laughed at him because he walked backward beneath the portico, he said to them: "Aren't you ashamed, you who walk backward along the whole path of existence, and blame me for walking backward along the path of the promenade?"

Assume, provisionally at any rate, a utilitarian ethic. The abolitionist project follows naturally, in "our" parochial corner of Hilbert space at least. On its completion, if not before, we should aim to develop superintelligence to maximise the well-being of the fragment of the cosmos accessible to beneficent intervention. And when we are sure - absolutely sure - that we have done literally everything we can do to eradicate suffering elsewhere, perhaps we should forget about its very existence.

Jupiter: I committed the first crime by creating men as mortals. After that, what more could you do, you the murderers?

Aegisteus: Come on; they already had death in them: at most you simply hastened things a little.

In an age of multiple and massive innovations, obsolescence becomes the major obsession.

The essence of the Liberal outlook lies not in what opinions are held, but in how they are held: instead of being held dogmatically, they are held tentatively, and with a consciousness that new evidence may at any moment lead to their abandonment.

As I take up my pen I feel myself so full, so equal to my subject, and see my book so clearly before me in embryo, I would almost like to try to say it all in a single word.

Hatred comes from the heart; contempt from the head; and neither feeling is quite within our control.

Now, let there be an indefinite succession of these inferential acts of comparative perception; and it is plain that the last moment will contain objectively the whole series. Let there be, not merely an indefinite succession, but a continuous flow of inference through a finite time; and the result will be a mediate objective consciousness of the whole time in the last moment. In this last moment, the whole series will be recognized, or known as known before.

A free society is a community of free beings, bound by the laws of sympathy and by the obligations of family love. It is not a society of people released from all moral constraint-for that is precisely the opposite of a society. Without moral constraint there can be no cooperation, no family commitment, no long-term prospects, no hope of economic, let alone social, order.

It is impossible to feel equal respect for things that are in fact unequal unless the respect is given to something that is identical in all of them. Men are unequal in all their relations with the things of this world, without exception. The only thing that is identical in all men is the presence of a link with the reality outside the world. All human beings are absolutely identical in so far as they can be thought of as consisting of a centre, which is an unquenchable desire for good, surrounded by an accretion of psychical and bodily matter.

No natural boundary seems to be set to the efforts of man; and what is not yet done is only what he has not yet attempted to do. Variant: What is not yet done is only what we have not yet attempted to do.

When contemporary feminist movement first began, feminist writings and scholarship by black women was groundbreaking. The writings of black women like Cellestine Ware, Toni Cade Bambara, Michele Wallace, Barbara Smith, and Angela Davis, to name a few, were all works that sought to articulate, define, speak to and against the glaring omissions in feminist work, the erasure of black female presence.

Thus the labour of a manufacture adds, generally, to the value of the materials which he works upon, that of his own maintenance, and of his masters profits. The labour of a menial servant, on the contrary, adds to the value of nothing.

The evolutionary urge drives man to seek for intenser forms of fulfillment, since his basic urge is for more life, more consciousness, and this contentment has an air of stagnation that the healthy mind rejects. (This recognition lies at the centre of my own 'outsider theory': that there are human beings to whom comfort means nothing, but whose happiness consists in following an obscure inner-drive, an 'appetite for reality'.)

Capitalism has brought about the emancipation of collective humanity with respect to nature. But this collective humanity has itself taken on with respect to the individual the oppressive function formerly exercised by nature.

Because the book became a freak 'bestseller', because I found myself bracketed with the 'Angry Young Men' of the period, I found myself carried to 'fame' on a wave of publicity -- only to discover that this kind of fame is one of the subtlest forms of obscurity. Everybody knew who I was, and nobody knew what I stood for. The public image meant that nobody was interested in what I had to say, for everyone was convinced that they already knew. I could talk until I was blue in the face about my attempt to revise the pessimistic existentialism of Heidegger, Camus and Sartre; as far as most people were concerned, I was an autodidact who was angry about something or other.

Of what I am, I know no more than that I am, but here no tie is necessary between subject and object. My own being is this tie, I am at once the subject knowing, and the object known of; and this reflection or return of the knowledge on itself is what I designate by the term I, if I have any determinate meaning.

The doctrine that all men are, in any sense, or have been, at any time, free and equal, is an utterly baseless fiction.

Man is certainly stark mad; he cannot make a worm, and yet he will be making gods by dozens.

All laws are... deduced from experiment; but to enunciate them, a special language is needful... ordinary language is too poor...This... is one reason why the physicist can not do without mathematics; it furnishes him the only language he can speak. And a well-made language is no indifferent thing;...the analyst, who pursues a purely esthetic aim, helps create, just by that, a language more fit to satisfy the physicist....law springs from experiment, but not immediately. Experiment is individual, the law deduced from it is general; experiment is only approximate, the law is precise...In a word, to get the law from experiment, it is necessary to generalize... But how generalize? ...in this choice what shall guide us?It can only be analogy. ...What has taught us to know the true profound analogies, those the eyes do not see but reason divines?It is the mathematical spirit, which disdains matter to cling only to pure form.

In my opinion, all things in nature occur mathematically.

Philosophy ... bears witness to the deepest love of reflection, to absolute delight in wisdom.

Dostoevsky once wrote: "If God did not exist, everything would be permitted"; and that, for existentialism, is the starting point. Everything is indeed permitted if God does not exist, and man is in consequence forlorn, for he cannot find anything to depend upon either within or outside himself. He discovers forthwith, that he is without excuse.

What if he has borrowed the matter and spoiled the form, as it oft falls out?

The advantage of pure, and the disadvantage of impure air are experienced each time we breathe, and all who understand the causes of disease know that an impure atmosphere is most unfavourable to the enjoyment of health, and an efficient cause to shorten human existence within the natural life of man. It is therefore most desirable that decisive measures should be devised and generally adopted to ensure to all a pure atmosphere, in which to live during their lives.

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.

For what is a child? Ignorance. What is a child? Want of instruction. For where a child has knowledge, he is no worse than we are.

The gentleman knows that whatever is imperfect and unrefined does not deserve praise. ... He makes his eyes not want to see what is not right, makes his ears not want to hear what is not right, makes his mouth not want to speak what is not right, and makes his heart not want to deliberate over what is not right. ... For this reason, power and profit cannot sway him, the masses cannot shift him, and nothing in the world can shake him.

Age may have one side, but assuredly Youth has the other. There is nothing more certain than that both are right, except perhaps that both are wrong. Let them agree to differ; for who knows but what agreeing to differ may not be a form of agreement rather than a form of difference?

Good and evil, reward and punishment, are the only motives to a rational creature: these are the spur and reins whereby all mankind are set on work, and guided.

No one knows what he can do till he tries.

Buddhism calls anger "corruption of the mind," Manicheism "root of the tree of death." I know this, but what good does it do me to know?

Yes perhaps, as the Sage says, "nothing worthy of proving can be proven, nor yet disproven"; but can we restrain that instinct which urges man to wish to know, and above all to wish to know the things which conduce to life, to eternal life? Eternal life, not eternal knowledge as the Alexandrian gnostic said. For living is one thing and knowing is another; and... perhaps there is an opposition between the two that we may say that everything vital is anti-rational, not merely irrational, and that everything rational is anti-vital. And this is the basis of the tragic sense of life.

Life is not so short but that there is always time enough for courtesy.

The cry of equality pulls everyone down.

The human body is essentially something other than an animal organism.

Rationality requires a complete knowledge and anticipation of the consequences that will follow on each choice. In fact, knowledge of consequences is always fragmentary.
