The repose of sleep refreshes only the body. It rarely sets the soul at rest. The repose of the night does not belong to us. It is not the possession of our being. Sleep opens within us an inn for phantoms. In the morning we must sweep out the shadows.

Newton... (after having remarked that geometry only requires two of the mechanical actions which it postulates, namely, to describe a straight line and a circle) says: geometry is proud of being able to achieve so much while taking so little from extraneous sources. One might say of metaphysics, on the other hand: it stands astonished, that with so much offered it by pure mathematics it can effect so little. In the meantime, this little is something which mathematics indispensably requires in its application to natural science, which, inasmuch as it must here necessarily borrow from metaphysics, need not be ashamed to allow itself to be seen in company with the latter.

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.

When you see a person squirming in the clutches of the Law, say to him: "Brother, get things straight. You let the Law talk to your conscience. Make it talk to your flesh.

Obsolescence is the moment of superabundance.

There is no cure for birth and death save to enjoy the interval.

If what the philosophers say be true,—that all men's actions proceed from one source; that as they assent from a persuasion that a thing is so, and dissent from a persuasion that it is not, and suspend their judgment from a persuasion that it is uncertain, so likewise they seek a thing from a persuasion that it is for their advantage.

So long as man remains free he strives for nothing so incessantly and so painfully as to find some one to worship.

Now, what is 'unrighteousness' in practice? It is in practice behavior of a kind disliked by the herd. By calling it unrighteousness, and by arranging an elaborate system of ethics around this conception, the herd justifies itself in wreaking punishment upon the objects of its own dislike, while at the same time, since the herd is righteous by definition, it enhances its own self-esteem at the very moment when it lets loose its impulse to cruelty. This is the psychology of lynching, and of the other ways in which criminals are punished. The essence of the conception of righteousness, therefore, is to afford an outlet for sadism by cloaking cruelty as justice.

Nihilism is not overcome by arguments or analyses; it is tamed by love and care. Any disease of the soul must be conquered by a turning of one's soul.

The papers were always talking about the debt owed to society. According to them, it had to be paid. But that doesn't speak to the imagination. What really counted was the possibility of escape, a leap to freedom, out of the implacable ritual, a wild run for it that would give whatever chance for hope there was. Of course, hope meant being cut down on some street corner, as you ran like mad, by a random bullet. But when I really thought it through, nothing was going to allow me such a luxury. Everything was against it; I would just be caught up in the machinery again.

To explain all nature is too difficult a task for any one man or even for any one age. 'Tis much better to do a little with certainty, & leave the rest for others that come after you, than to explain all things by conjecture without making sure of any thing.

He was always smoothing and polishing himself, and in the end he became blunt before he was sharp.

We ourselves are the entities to be analyzed.

Temperance is that discreet regulation of the desires and passions, by which we are enabled to enjoy pleasures without suffering any consequent inconvenience. They who maintain such a constant self-command, as never to be enticed by the prospect of present indulgence, to do that which will be productive of evil, obtain the truest pleasure by declining pleasure.

As the brain-changes are continuous, so do all these consciousnesses melt into each other like dissolving views. Properly they are but one protracted consciousness, one unbroken stream.

Do a man dirt, yourself you hurt.

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.

Silence is the virtue of a fool.

I think modern educational theorists are inclined to attach too much importance to the negative virtue of not interfering with children, and too little to the positive merit of enjoying their company.

Either the USSR was not the country of socialism, in which case socialism didn't exist anywhere and doubtless, wasn't possible: or else, socialism was that, this abominable monster, this police state, the power of beasts of prey.

The real field of knowledge is not the given fact about things as they are, but the critical evaluation of them as a prelude to passing beyond their given form. Knowledge deals with appearances in order to get beyond them. .... The concept of reality has thus turned into the concept of possibility. The real is not yet 'actual,' but is at first only the possibility of an actual.

Those who used to sacrifice animals did not take them for beasts. And even the Middle Ages, which condemned and punished them in due form, was in this way much closer to them than we are, we who are filled with horror at this practice. They held them to be guilty: which was a way of honoring them. We take them for nothing, and it is on this basis that we are "human" with them. We no longer sacrifice them, we no longer punish them, and we are proud of it, but it is simply that we have domesticated them, worse: that we have made of them a racially inferior world, no longer even worthy of our justice, but only of our affection and social charity, no longer worthy of punishment and of death, but only of experimentation and extermination like meat from the butchery.

There is no road or ready way to virtue.

Tears do not burn except in solitude.

These Lectures, conjoined with those which have already appeared under the titles of "The Characteristics of the Present Age," and "The Nature of the Scholar," in the latter of which the tone of thought that governs the present course is applied to a particular subject, form a complete scheme of popular instruction, of which the present work exhibits the highest and clearest summit; and, taken together, they are the result of a process of self-culture, unceasingly pursued during the last six or seven years of my life, with greater leisure and in riper maturity, by means of that Philosophy in which I have been a partaker for thirteen years, and which, although, I hope, it has changed many things in me, has nevertheless itself suffered no change whatever during that period.

Practice justice in word and deed, and do not get in the habit of acting thoughtlessly about anything.

My Lord St. Albans said that Nature did never put her precious jewels into a garret four stories high, and therefore that exceeding tall men had ever very empty heads.

This very second has vanished forever, lost in the anonymous mass of the irrevocable. It will never return. I suffer from this and I do not. Everything is unique - and insignificant.

The first character of a general idea so resulting is that it is living feeling. A continuum of this feeling, infinitesimal in duration, but still embracing innumerable parts, and also, though infinitesimal, entirely unlimited, is immediately present. And in its absence of boundedness a vague possibility of more than is present is directly felt.

Nonviolence does not necessarily emerge from a pacific or calm part of the soul. Very often it is an expression of rage, indignation, and aggression.

We must plow through the whole of language.

But by far the greatest obstacle to the progress of science and to the undertaking of new tasks and provinces therein is found in this - that men despair and think things impossible.

Our patience will achieve more than our force.

I am firmly convinced, therefore, that to set up a republic which is to last a long time, the way to set about it is to constitute it as Sparta and Venice were constituted; to place it in a strong position, and so to fortify it that no one will dream of taking it by a sudden assault; and, on the other hand, not to make it so large as to appear formidable to its neighbors. It should in this way be able to enjoy its form of government for a long time. For war is made on a commonwealth for two reasons: to subjugate it, and for fear of being subjugated by it.

Actual aristocracy cannot be abolished by any law: all the law can do is decree how it is to be imparted and who is to acquire it.

If the slavery of the parents be unjust, much more is their children's; if the parents were justly slaves, yet the children are born free; this is the natural, perfect right of all mankind; they are nothing but a just recompense to those who bring them up: And as much less is commonly spent on them than others, they have a right, in justice, to be proportionably sooner free.

Perfectibility is one of the most unequivocal characteristics of the human species.

If all men, by the act of being born, are destined to suffer violence, that is a truth to which the empire of circumstances closes their minds.

The texts about the future life fall into, since demonstrative scholars do not agree whether to take them in their apparent meaning or interpret them allegorically. Either is permissible. But it is inexcusable to deny the fact of a future life altogether.

Unless man have a natural bent in accordance with nature's, he has no chance of understanding nature at all.

Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets.

I retain my faith in the humanist tradition, that it's possible to deal with discrepant experiences truthfully without resolving into simple things like only women should write about women, only Chicanos should write about Chicanos, only Latinos should write about Latinos... I think that's the most damaging crime, and misapprehension of what I'm saying. That's why they debate all these things and they trace them back to me and people say 'you did that!' Absolutely not. I'm talking from a universalistic, if you like cosmopolitan point of view to which I adhere and which is the only way the world makes sense to me. I don't believe in the politics of identity, although in many ways paradoxically I seem to be the father of identity politics, but it's a thing I totally disbelieve in because I realise the damage that identities have done.

We scarce ever had a prince, who by fraud, or violence, had not made some infringement on the constitution. We scarce ever had a parliament which knew, when it attempted to set limits to the royal authority, how to set limits to its own. Evils we have had continually calling for reformation, and reformations more grievous than any evils. Our boasted liberty sometimes trodden down, sometimes giddily set up, and ever precariously fluctuating and unsettled; it has only been kept alive by the blasts of continual feuds, wars, and conspiracies.

Pray go back and recollect one of the conclusions to which I sought to lead you in my very first lecture. You may remember how I there argued against the notion that the worth of a thing can be decided by its origin. Our spiritual judgment, I said, our opinion of the significance and value of a human event or condition, must be decided on empirical grounds exclusively. If the fruits for life of the state of conversion are good, we ought to idealize and venerate it, even though it be a piece of natural psychology; if not, we ought to make short work of it, no matter what supernatural being may have infused it.

I did not know that mankind were suffering for want of gold. I have seen a little of it. I know that it is very malleable, but not so malleable as wit. A grain of gold will gild a great surface, but not so much as a grain of wisdom.

Hardness and softness, roughness and smoothness, moonlight and sunlight present themselves in our recollection not preeminently as sensory contents but as certain kinds of symbioses, certain ways outside has of invading us and certain ways we have of meets this invasion...

Despite the fact that the doctors treated him, bled him, and gave him medicines to drink, he recovered.
