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.

Native societies did not think of themselves as being in the world as occupants but considered that their rituals created the world and keep it operational.

I dislike Communism because it is undemocratic, and capitalism because it favors exploitation.

If, then, a phenomenon admits of a complete mechanical explanation, it will admit of an infinity of others, that will render an account equally well of all the particulars revealed by experiment.

It was his peculiar doctrine that a man has a perfect right to interfere by force with the slaveholder, in order to rescue the slave. I agree with him. They who are continually shocked by slavery have some right to be shocked by the violent death of the slaveholder, but no others.

The closed language does not demonstrate and explain-it communicates decision, dictum, command. Where it defines, the definition becomes "separation of good from evil;" it establishes unquestionable.

The fact of being within capital and sustaining capital is what defines the proletariat as a class.

I cannot guess what may be the fate of Quakerism in America; but I perceive it loses ground daily in England. In all countries, where the established religion is of a mild and tolerating nature, it will at length swallow up all the rest.

The evil effect of science upon men is principally this, that by far the greatest number of those who wish to display a knowledge of it accomplish no improvement at all of the understanding, but only a perversity of it, not to mention that it serves most of them as a tool of vanity.

When I found myself regarded as respectable, I began to wonder what sins I had committed. I must be very wicked, I thought. I began to engage in the most uncomfortable introspection. Interview with Irwin Ross, September 1957;If there were a God, I think it very unlikely that he would have such an uneasy vanity as to be offended by those who doubt his existence.

If anything extraordinary seems to have happened, we can always say that we have been the victims of an illusion. If we hold a philosophy which excludes the supernatural, this is what we always shall say.

For nothing can be greater than seduction itself, not even the order that destroys it.

There is room in the world, no doubt, and even in old countries, for a great increase of population, supposing the arts of life to go on improving, and capital to increase. But even if innocuous, I confess I see very little reason for desiring it. The density of population necessary to enable mankind to obtain, in the greatest degree, all the advantages both of co-operation and of social intercourse, has, in all the most populous countries, been attained. If the earth must lose that great portion of its pleasantness which it owes to things that the unlimited increase of wealth and population would extirpate from it, for the mere purpose of enabling it to support a larger but not a better or a happier population, I sincerely hope, for the sake of posterity, that they will be content to be stationary, long before necessity compels them to it..

The first thinker was, without a doubt, the first man obsessed by why. An unaccustomed mania, not at all contagious: rare indeed are those who suffer from it, who are a prey to questioning, and who can accept no given because they were born in consternation.

It is only the individual possessed of the most entire sincerity that can exist under Heaven, who can adjust the great invariable relations of mankind, establish the great fundamental virtues of humanity, and know the transforming and nurturing operations of Heaven and Earth; shall this individual have any being or anything beyond himself on which he depends? Call him man in his ideal, how earnest is he! Call him an abyss, how deep is he! Call him Heaven, how vast is he! Who can know him, but he who is indeed quick in apprehension, clear in discernment, of far-reaching intelligence, and all-embracing knowledge, possessing all Heavenly virtue?

History has informed us that bodies of men, as well as individuals, are susceptible of the spirit of tyranny.

No man can have a peaceful life who thinks too much about lengthening it.

TV is not good at covering single events. It needs a ritual, a rhythm, and a pattern...[TV] tends to fosters patterns rather than events.

That I, a funny little gesticulating animal on two legs, should stand beneath the stars and declaim in a passion about my rights - it seems so laughable, so out of all proportion. Much better, like Archimedes, to be killed because of absorption in eternal things... There is a possibility in human minds of something mysterious as the night-wind, deep as the sea, calm as the stars, and strong as Death, a mystic contemplation, the "intellectual love of God." Those who have known it cannot believe in wars any longer, or in any kind of hot struggle. If I could give to others what has come to me in this way, I could make them too feel the futility of fighting. But I do not know how to communicate it: when I speak, they stare, applaud, or smile, but do not understand.

By necrophilia is meant love for all that is violence and destruction; the desire to kill; the worship of force; attraction to death, to suicide, to sadism; the desire to transform the organic into the inorganic by means of "order." The necrophile, lacking the necessary qualities to create, in his impotence finds it easy to destroy because for him it serves only one quality: force.

The best friend is he that, when he wishes a person's good, wishes it for that person's own sake.

From the fundamental nature of the Philistine, it follows that, in regard to others, as he has no intellectual but only physical needs, he will seek those who are capable of satisfying the latter not the former. And so of all the demands he makes of others the very smallest will be that of any outstanding intellectual abilities. On the contrary, when he comes across these they will excite his antipathy and even hatred. For here he has a hateful feeling of inferiority and also a dull secret envy which he most carefully attempts to conceal even from himself; but in this way it grows sometimes into a feeling of secret rage and rancour. Therefore it will never occur to him to assess his own esteem and respect in accordance with such qualities, but they will remain exclusively reserved for rank and wealth, power and influence, as being in his eyes the only real advantages to excel in which is also his desire.

There is no spirit-driven life force, no throbbing, heaving, pullulating, protoplasmic, mystic jelly. Life is just bytes and bytes and bytes of digital information.

People try to get away from it all-to the country, to the beach, to the mountains. You always wish that you could too. Which is idiotic: you can get away from it anytime you like. By going within. Nowhere you can go is more peaceful-more free of interruptions-than your own soul.

When shall we see poets born? After a time of disasters and great misfortunes, when harrowed nations begin to breathe again. And then, shaken by the terror of such spectacles, imaginations will paint things entirely strange to those who have not witnessed them.

The principle of brotherhood expounded by the agitator of Nazareth preserved the germ of life, of truth and justice, so long as it was the beacon light of the few. The moment the majority seized upon it, that great principle became a shibboleth and harbinger of blood and fire, spreading suffering and disaster. The attack on the omnipotence of Rome was like a sunrise amid the darkness of the night, only so long as it was made by the colossal figures of a Huss, a Calvin, or a Luther. Yet when the mass joined in the procession against the Catholic monster, it was no less cruel, no less bloodthirsty than its enemy. Woe to the heretics, to the minority, who would not bow to its dicta. After infinite zeal, endurance, and sacrifice, the human mind is at last free from the religious phantom; the minority has gone on in pursuit of new conquests, and the majority is lagging behind, handicapped by truth grown false with age.

Consciousness is much more than the thorn, it is the dagger in the flesh.

There is nothing in any object, consider'd in itself, which can afford us a reason for drawing a conclusion beyond it; even after the observation of the frequent or constant conjunction of objects, we have no reason to draw any inference concerning any object beyond those of which we have had experience.

The ruling power within, when it is in its natural state, is so related to outer circumstances that it easily changes to accord with what can be done and what is given it to do.

The "social contract," in the only sense in which it is not completely mythical, is a contract among conquerors, which loses its raison d'être if they are deprived of the benefits of conquest.

An army and navy represents the people's toys.

Mathematics, rightly viewed, possesses not only truth, but supreme beauty - a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of highest excellence, is to be found in mathematics as surely as in poetry. What is best in mathematics deserves not merely to be learnt as a task, but to be assimilated as a part of daily thought, and brought again and again before the mind with ever-renewed encouragement.

Since... nature is a principle of motion and mutation... it is necessary that we should not be ignorant of what motion is... But motion appears to belong to things continuous; and the infinite first presents itself to the view in that which is continuous. ...Frequently ...those who define the continuous, employ the nature or the infinite, as if that which is divisible to infinity is continuous.

The skepticism which fails to contribute to the ruin of our health is merely an intellectual exercise.

When he was asked what advantage had accrued to him from philosophy, his answer was, "The ability to hold converse with myself."

Wandering in a vast forest at night, I have only a faint light to guide me. A stranger appears and says to me: "My friend, you should blow out your candle in order to find your way more clearly." This stranger is a theologian.

In our science and philosophy, even, there is commonly no true and absolute account of things. The spirit of sect and bigotry has planted its hoof amid the stars. You have only to discuss the problem, whether the stars are inhabited or not, in order to discover it.

Liberty, taking the word in its concrete sense, consists in the ability to choose.

I would rather discover one cause than gain the kingdom of Persia.

Time and Space ... It is not nature which imposes them upon us, it is we who impose them upon nature because we find them convenient.

We are not afraid to follow truth wherever it may lead, nor to tolerate any error so long as reason is left free to combat it.

Remember, that to change thy mind upon occasion, and to follow him that is able to rectify thee, is equally ingenuous, as to find out at the first, what is right and just, without help. For of thee nothing is required, that is beyond the extent of thine own deliberation and judgment, and of thine own understanding.

There is no work so mean, but it would amply serve me to furnish me with sustenance.

I have taken pains to make my distinction of icons, indices, and tokens clear, in order to enunciate this proposition: in a perfect system of logical notation signs of these several kinds must all be employed. Without tokens there would be no generality in the statements, for they are the only general signs; and generality is essential to reasoning. ... But tokens alone do not state what is the subject of discourse ; and this can, in fact, not be described in general terms ; it can only be indicated. The actual world cannot be distinguished from a world of imagination by any description. Hence the need of pronoun and indices, and the more complicated the subject the greater the need of them.

If... it be supposed that another way of measuring time is adopted... enunciation of the law would be... translated into another language... much less simple. So that the definition implicitly adopted by the astronomers may be summed up..: Time should be so defined that the equations of mechanics may be as simple as possible... [i.e.,] there is not one way of measuring time more true... only more convenient.

Direct action, having proven effective along economic lines, is equally potent in the environment of the individual. There a hundred forces encroach upon his being, and only persistent resistance to them will finally set him free. Direct action against the authority in the shop, direct action against the authority of the law, direct action against the invasive, meddlesome authority of our moral code, is the logical, consistent method of Anarchism. Will it not lead to a revolution? Indeed, it will. No real social change has ever come about without a revolution. People are either not familiar with their history, or they have not yet learned that revolution is but thought carried into action.

But to return to the Jewish question. Other groups and nations cultivate their individual traditions. There is no reason why we should sacrifice ours. Standardization robs life of its spice. To deprive every ethnic group of its special traditions is to convert the world into a huge Ford plant. I believe in standardizing automobiles. I do not believe in standardizing human beings. Standardization is a great peril which threatens American culture.
