How significant is the enormous heightening, under mescalin, of the perception of color! ... Man's highly developed color sense is a biological luxury-inestimably precious to him as an intellectual and spiritual being, but unnecessary to his survival as an animal. ... Mescalin raises all colors to a higher power and makes the percipient aware of innumerable fine shades of difference, to which, at ordinary times, he is completely blind. It would seem that, for Mind at Large, the so-called secondary characters of things are primary.

I veil my face before thee, and lay my finger on my lips. What thou art in thyself, or how thou appearest to thyself, I can never know. After living through a thousand lives, I shall comprehend Thee as little as I do now in this mansion of clay. What I can comprehend, becomes finite by my mere comprehension, and this can never, by perpetual ascent, be transformed into the infinite, for it does not differ from it in degree merely, but in kind. By that ascent we may find a greater and greater man, but never a God, who is capable of no measurement.

Every philosophical problem, when it is subjected to the necessary analysis and justification, is found either to be not really philosophical at all, or else to be, in the sense in which we are using the word, logical.

The problem is not to discover in oneself the truth of one's sex, but, rather, to use one's sexuality henceforth to arrive at a multiplicity of relationships. And, no doubt, homosexuality is not a form of desire but something desirable. Therefore, we have to work at becoming homosexuals.

The Americans combine the notions of Christianity and of liberty so intimately in their minds, that it is impossible to make them conceive the one without the other; and with them this conviction does not spring from that barren traditionary faith which seems to vegetate in the soul rather than to live.

But ordinary language is all right.

Words ... are little houses, each with its cellar and garret. Common sense lives on the ground floor, always ready to engage in 'foreign commerce' on the same level as the others, as the passers-by, who are never dreamers. To go upstairs in the word house is to withdraw step by step; while to go down to the cellar is to dream, it is losing oneself in the distant corridors of an obscure etymology, looking for treasures that cannot be found in words. To mount and descend in the words themselves-this is a poet's life. To mount too high or descend too low is allowed in the case of poets, who bring earth and sky together.

Power as is really divided, and as dangerously to all purposes, by sharing with another an Indirect Power, as a Direct one.

The man that does not know himself not to be at the mercy of other men, that does not feel that he is invulnerable to all the vicissitudes of fortune, is incapable of a constant and inflexible virtue.

In contrast to "Blessed are they who do not see and still believe," he speaks of "seeing and still not believing."

In every man sleeps a prophet, and when he wakes there is a little more evil in the world

We live, in fact, in a world starved for solitude, silence, and privacy: and therefore starved for meditation and true friendship.

He who does wrong is more unhappy than he who suffers wrong.

To study and not think is a waste. To think and not study is dangerous. Learning without thought is labor lost; thought without learning is perilous.

There are and can be only two ways of searching into and discovering truth. The one flies from the senses and particulars to the most general axioms, and from these principles, the truth of which it takes for settled and immovable, proceeds to judgment and to the discovery of middle axioms. And this way is now in fashion. The other derives axioms from the senses and particulars, rising by a gradual and unbroken ascent, so that it arrives at the most general axioms last of all. This is the true way, but as yet untried.

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

I assert once again as a truth to which history as a whole bears witness that men may second their fortune, but cannot oppose it; that they may weave its warp, but cannot break it. Yet they should never give up, because there is always hope, though they know not the end and more towards it along roads which cross one another and as yet are unexplored; and since there is hope, they should not despair, no matter what fortune brings or in what travail they find themselves.

She is the sum of nature's universe.To her perfection all of beauty tends.

Men love to wonder, and that is the seed of our science. 

Every oasis is an island that has water inside it but not round it.

I am no longer sure of anything. If I satiate my desires, I sin but I deliver myself from them; if I refuse to satisfy them, they infect the whole soul.

The core of the belief in progress is that human values and goals converge in parallel with our increasing knowledge. The twentieth century shows the contrary. Human beings use the power of scientific knowledge to assert and defend the values and goals they already have. New technologies can be used to alleviate suffering and enhance freedom. They can, and will, also be used to wage war and strengthen tyranny. Science made possible the technologies that powered the industrial revolution. In the twentieth century, these technologies were used to implement state terror and genocide on an unprecedented scale. Ethics and politics do not advance in line with the growth of knowledge - not even in the long run.

One principle, that I believe is wanting in you, and all our too fervent and impetuous reformers, is the thought, that almost every institution or form of society is good in its place, and in the period of time to which it belongs. How many beautiful and admirable effects grew out of Popery and the monastic institutions, in the period, when they were in their genuine health and vigour! To them we owe almost all our logic and our literature. What excellent effects do we reap, even at this day, from the feudal system and from chivalry! In this point of view, nothing can, perhaps, be more worthy of our applause than the English constitution.

Success treads on every right step. For the instinct is sure, that prompts him to tell his brother what he thinks. He then learns, that in going down into the secrets of his own mind, he has descended into the secrets of all minds. He learns that he who has mastered any law in his private thoughts, is master to that extent of all men whose language he speaks, and of all into whose language his own can be translated.

Slavery is disheartening; but Nature is not so helpless but it can rid itself of every last wrong. But the spasms of nature are centuries and ages and will tax the faith of short-lived men. Slowly, slowly the Avenger comes, but comes surely. The proverbs of the nations affirm these delays, but affirm the arrival. They say, "God may consent, but not forever." The delay of the Divine Justice - this was the meaning and soul of the Greek Tragedy, - this was the soul of their religion.

Survival machines that can simulate the future are one jump ahead of survival machines that who can only learn of the basis of trial and error. The trouble with overt trial is that it takes time and energy. The trouble with overt error is that it is often fatal. ...The evolution of the capacity to simulate seems to have culminated in subjective consciousness. Why this should have happened is, to me, the most profound mystery facing modern biology.

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.

A man's reach must exceed his grasp or what's a metaphor?

The erotic instinct is something questionable, and will always be so whatever a future set of laws may have to say on the matter. It belongs, on the one hand, to the original animal nature of man, which will exist as long as man has an animal body. On the other hand, it is connected with the highest forms of the spirit. But it blooms only when the spirit and instinct are in true harmony. If one or the other aspect is missing, then an injury occurs, or at least there is a one-sided lack of balance which easily slips into the pathological. Too much of the animal disfigures the civilized human being, too much culture makes a sick animal.

One may be humble out of pride.

The subject must distinguish itself through opposition from the rational being, which it has assumed outside of itself. The subject has posited itself as one, which contains in itself the last ground of something that is in it, (for this is the condition of Egohood, or of Rationality generally;) but it has also posited a being outside of itself, as the last ground of this something in it. It is to have the power of distinguishing itself from this other being; and this is, under our presupposition, possible only, if the subject can distinguish in that given something how far the ground of this something lies in itself and how far it lies outside of itself.

Modern physics... reduces matter to a set of events which proceed outward from a centre. If there is something further in the centre itself, we cannot know about it, and it is irrelevant to physics.

I have in general no very exalted opinion of the virtue of paper government.

That which parents should take care of... is to distinguish between the wants of fancy, and those of nature.

This book is intended as a correlative history of the modern soul and of a new power to judge; a genealogy of the present scientifico-legal complex from which the power to punish derives its bases, justifications and rules, from which it extends its effects and by which it extends its effects and by which it masks its exorbitant singularity.

If we cut up beasts simply because they cannot prevent us and because we are backing our own side in the struggle for existence, it is only logical to cut up imbeciles, criminals, enemies, or capitalists for the same reasons.

There is always a best way of doing everything, if it be to boil an egg. Manners are the happy ways of doing things; each once a stroke of genius or of love, - now repeated and hardened into usage. They form at last a rich varnish, with which the routine of life is washed, and its details adorned.

Intense, long, certain, speedy, fruitful, pure-Such marks in pleasures and in pains endure.Such pleasures seek if private be thy end:If it be public, wide let them extend.Such pains avoid, whichever be thy view:If pains must come, let them extend to few.

The very desire for guarantees that our values are eternal and secure in some objective heaven is perhaps only a craving for the certainties of childhood or the absolute values of our primitive past.

Fortitude, the virtue which enables us to endure pain, and to banish fear, is of great use in producing tranquility. Philosophy instructs us to pay homage to the gods, not through hope or fear, but from veneration of their superior nature. It moreover enables us to conquer the fear of death, by teaching us that it is no proper object of terror; since, whilst we are, death is not, and when death arrives, we are not: so that it neither concerns the living nor the dead.

All men cannot receive this saying, save they to whom it is given. For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.

It would be worth the while to look closely into the eye which has been open and seeing at such hours, and in such solitudes, its dull, yellowish, greenish eye. Methinks my own soul must be a bright invisible green.

Homer has taught all other poets the art of telling lies skillfully.

Suppose that I wish to deserve the title of "robber of remorse" and that I place in myself all [the townspeople's] repentence?

In proportion as a man's interests become humane and his efforts rational, he appropriates and expands a common life, which reappears in all individuals who reach the same impersonal level of ideas.

The stars are scattered all over the sky like shimmering tears, there must be great pain in the eye from which they trickled.

All things must needs be borne on through the calm void moving at equal rate with unequal weights.

The pit of a theatre is the one place where the tears of virtuous and wicked men alike are mingled.

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.
