How can you reach the womb of the Abyss to make it fruitful? This cannot be expressed, cannot be narrowed into words, cannot be subjected to laws; every man is completely free and has his own special liberation. No form of instruction exists, no Savior exists to open up the road. No road exists to be opened.

Gender is a kind of imitation for which there is no original; in fact, it is a kind of imitation that produces the very notion of the original as an effect and consequence of the imitation itself.

Being true is different from being taken as true, whether by one or by many or everybody, and in no case is it to be reduced to it. There is no contradiction in something's being true which everybody takes to be false. I understand by 'laws of logic' not psychological laws of takings-to-be-true, but laws of truth. ...If being true is thus independent of being acknowledged by somebody or other, then the laws of truth are not psychological laws: they are boundary stones set in an eternal foundation, which our thought can overflow, but never displace. It is because of this that they have authority for our thought if it would attain truth. They do not bear the relation to thought that the laws of grammar bear to language; they do not make explicit the nature of our human thinking and change as it changes.

It is simply no good trying to keep any thrill: that is the very worst thing you can do. Let the thrill go-let it die away-go on through that period of death into the quieter interest and happiness that follow-and you will find you are living in a world of new thrills all the time. But if you decide to make thrills your regular diet and try to prolong them artificially, they will all get weaker and weaker, and fewer and fewer, and you will be a bored, disillusioned old man for the rest of your life. It is because so few people understand this that you find many middle-aged men and women maundering about their lost youth, at the very age when new horizons ought to be appearing and new doors opening all round them. It is much better fun to learn to swim than to go on endlessly (and hopelessly) trying to get back the feeling you had when you first went paddling as a small boy.

I was a solitary, shy, priggish youth. I had no experience of the social pleasures of boyhood and did not miss them. But I liked mathematics, and mathematics was suspect because it has no ethical content. I came also to disagree with the theological opinions of my family, and as I grew up I became increasingly interested in philosophy, of which they profoundly disapproved. Every time the subject came up they repeated with unfailing regularity, 'What is mind? No matter. What is matter? Never mind.' After some fifty or sixty repetitions, this remark ceased to amuse me.

Inferiority is always with us, and merciless scorn of it is the keynote of the military temper.

People travel to wonder at the height of mountains, at the huge waves of the sea, at the long courses of rivers, at the vast compass of the ocean, at the circular motion of the stars; and they pass by themselves without wondering.

If you tried to doubt everything you would not get as far as doubting anything. The game of doubting itself presupposes certainty.

Mechanical, chemical, and vital Forces form an ascending progression, each including the preceding. Chemical Affinity includes in its nature Mechanical Force, and may often be practically resolved into Mechanical Force. (Thus the ingredients of gunpowder, liberated from their chemical union, exert great mechanical Force : a galvanic battery acting by chemical process does the like.) Vital Forces include in their nature both chemical Affinities and mechanical Forces: for Vital Powers produce both chemical changes, (digestion,) and motions which imply considerable mechanical force, (as the motion of the sap and of the blood.)

What I liked was Thatcherism's Bolshevik aspect, which was to shake up the whole of Britain quite fundamentally, and if you read what I wrote in those years I think you might agree that in taking the view that I did then - that this was necessary and desirable - I never subscribed to the main delusion of the Thatcherites, which was that you could change everything and everything would remain the same. If what you wanted was a very anarchic, globalised, polyglot, mixed-up society in which most of the structures which had somehow been renewed from the Edwardian period to the Sixties were destroyed, then Thatcherism was what would do the job.

Besides, he who follows another not only discovers nothing but is not even investigating.

It is not your strength and your natural power that subjects all these people to you. Do not pretend then to rule them by force or to treat them with harshness. Satisfy their reasonable desires; alleviate their necessities; let your pleasure consist in being beneficent; advance them as much as you can, and you will act like the true king of desire.

The force of mind is only as great as its expression; its depth only as deep as its power to expand and lose itself.

Truth that is naked is the most beautiful, and the simpler its expression the deeper is the impression it makes; this is partly because it gets unobstructed hold of the hearer's mind without his being distracted by secondary thoughts, and partly because he feels that here he is not being corrupted or deceived by the arts of rhetoric, but that the whole effect is got from the thing itself.

More controversially, technology can accelerate the transition from harming to helping free-living sentient beings: mankind's fitfully expanding "circle of compassion". The civilising process needn't be species-specific but instead extend to free-living dwellers in tomorrow's wildlife parks. Every cubic metre of the biosphere will soon be computationally accessible to surveillance, micro-management and control. Fertility regulation via immunocontraception can replace Darwinian ecosystems governed by starvation and predation. Any species of obligate carnivore we choose to preserve can be genetically and behaviourally tweaked into harmlessness. Asphyxiation, disembowelling, and agonies of being eaten alive can pass into the dustbin of history.

I had better never see a book than to be warped by its attraction clean out of my own orbit, and made a satellite instead of a system. The one thing in the world, of value, is the active soul.

We are organization watchers in our role as citizens. Increasing attention has been fixed in recent years upon the functioning of society's organizations: its large corporations and its governments. Hence this could also be described as a book for Everyman-for it proposes a way of thinking about organizational issues that concern us all.

That knowledge which adds greatness to character is knowledge so handled as to transform every phase of immediate experience.

Yes, so it is that knowledge itself must die in order to blossom forth again in death as will; the freedom of thought, belief, and conscience, these wonderful flowers of three centuries will sink back into the lap of mother earth so that a new freedom, the freedom will, will be nourished with its most noble juices.

The truth can wait, for she lives a long life.

It belongs to the imperfection of everything human that man can only attain his desire by passing through its opposite.

In the long run, there is nothing to stop intelligent agents from identifying the molecular signature of experience below hedonic zero and eliminating it altogether - even in insects. Nociception is vital; pain is optional. I tentatively predict that the world's last unpleasant experience in our forward light-cone will be a precisely datable event - perhaps some micro-pain in an obscure marine invertebrate a few centuries hence.

The following general definition of an animal: a system of different organic molecules that have combined with one another, under the impulsion of a sensation similar to an obtuse and muffled sense of touch given to them by the creator of matter as a whole, until each one of them has found the most suitable position for it shape and comfort.

But voice is a certain sound of that which is animated; for nothing inanimate emits a voice; but they are said to emit a voice from similitude, as a pipe, and a lyre, and such other inanimate things, have extension, modulation, and dialect; for thus it appears, because voice, also, has these.

If I had had more time, this letter would have been shorter.

It appears that liberty is bound up with imperfection, with a right to imperfection. Socialism leads to the same type of authoritarian state as Theocracy. ... One must choose: either Socialism or liberty of spirit, the liberty of man's conscience. ... Socialism uses a "sacred" authority and establishes a "sacred" society in which there is no place for the "lay," for the free, for choice, for the unrestrained activity of human forces.

To pray to God is to flatter oneself that with words one can alter nature.

Understand me well. My appeal is to observation - observation that each of you must make for himself.

It is not proper either to have a blunt sword or to use freedom of speech ineffectually. Neither is the sun to be taken from the world, nor freedom of speech from erudition.

The mathematical thermology created by Fourier may tempt us to hope that, as he has estimated the temperature of the space in which we move, me may in time ascertain the mean temperature of the heavenly bodies: but I regard this order of facts as for ever excluded from our recognition. We can never learn their internal constitution, nor, in regard to some of them, how heat is absorbed by their atmosphere. We may therefore define Astronomy as the science by which we discover the laws of the geometrical and mechanical phenomena presented by the heavenly bodies.

Every uneducated person is a caricature of himself.

The journalists have constructed for themselves a little wooden chapel, which they also call the Temple of Fame, in which they put up and take down portraits all day long and make such a hammering you can't hear yourself speak.

Subject matters in general do not exist. There are no subject matters; no branches of learning-or, rather, of inquiry: there are only problems, and the urge to solve them.

Do not all theists insist that there can be no morality, no justice, honesty or fidelity without the belief in a Divine Power? Based upon fear and hope, such morality has always been a vile product, imbued partly with self-righteousness, partly with hypocrisy. As to truth, justice, and fidelity, who have been their brave exponents and daring proclaimers? Nearly always the godless ones: the Atheists; they lived, fought, and died for them. They knew that justice, truth, and fidelity are not conditioned in heaven, but that they are related to and interwoven with the tremendous changes going on in the social and material life of the human race; not fixed and eternal, but fluctuating, even as life itself.

Too little liberty brings stagnation, and too much brings chaos.

Much must also be withdrawn into oneself: for a well-composed conversation of differences disturbs and renews the affections, and infuriates whatever is weak in the mind and has not been cared for...Loneliness will cure the hatred of the crowd, the boredom of solitude will be cured by the crowd.... A certain dullness and languor of the mind is born from constant toil....Nor would the desire of men so much tend to this, unless play and fun had a kind of natural voluptuousness. The frequent use of which will relieve all the weight of the soul and all the vigor.For sleep is also necessary for refreshment, but if you continue it day and night, death will result.

The happiness and unhappiness of the rational, social animal depends not on what he feels but on what he does; just as his virtue and vice consist not in feeling but in doing.

Driving is a spectacular form of amnesia. Everything is to be discovered, everything to be obliterated. Admittedly, there is the primal shock of the deserts and the dazzle of California, but when this is gone, the secondary brilliance of the journey begins, that of the excessive, pitiless distance, the infinity of anonymous faces and distances, or of certain miraculous geological formations, which ultimately testify to no human will, while keeping intact an image of upheaval. This form of travel admits of no exceptions: when it runs up against a known face, a familiar landscape, or some decipherable message, the spell is broken: the amnesic, ascetic, asymptotic charm of disappearance succumbs to affect and worldly semiology.

Cheating ageing by a low-calorie diet, uploading one's mind into a super-computer, migrating into outer space ... Longing for everlasting life, humans show that they remain the death-defined animal.

I have always noticed that deeply and truly religious persons are fond of a joke, and I am suspicious of those who aren't.

When we see civilization elated with this declining and decrepit phase of its career, we are reminded of a faded belle who, boasting of her attractions in her fiftieth year, excites at once the remark that she was fairer at twenty-five. So it is with civilization, which, dreaming of perfection and progress, is constantly deteriorating, and which will find but too soon in its industrial achievements new sources of political oppression, crimes and commotions.

"What is meant by saying that my choice of which way to walk home after the lecture is ambiguous and matter of chance?...It means that both Divinity Avenue and Oxford Street are called but only one, and that one either one, shall be chosen.

When I hear any man talk of an unalterable law, the only effect it produces upon me is to convince me that he is an unalterable fool.

The jingoes and war speculators are filling the air with the sentimental slogan of hypocritical nationalism, "America for Americans," "America first, last, and all the time."

But here is the "ego" of the Russian revolutionary again! Pirouetting on its head, it once more proclaims itself to be the all-powerful director of history - this time with the title of His Excellency the Central Committee of the Social Democratic Party of Russia.
