The mother tongue is propaganda.

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.

The whole world is in some ways better than it's ever been in the past. And, indeed, I think for many people the meaning of their lives really depends on that belief. If you strip out that belief in progress, if you start thinking of the world in the way in which the ancient pre-Christian Europeans did, or the Buddhists and the Hindus or the Taoists of China do, many people think that's a kind of despair. I don't know how many times I've been told "If I thought that, John, I wouldn't get up in the morning" and "If I agreed with you, John, that history had no pattern of that kind, I wouldn't get up in the morning." I said, "Well, stay in bed a bit longer, you might find a better reason for getting up."

If a thousand citizens were not to pay their tax-bills this year, that would not be a violent and bloody measure, as it would be to pay them, and enable the State to commit violence and shed innocent blood. This is, in fact, the definition of a peaceable revolution, if any such is possible.

Fine manners need the support of fine manners in others, and this is a gift interred only by the self.

The whole analogy of natural operations furnishes so complete and crushing an argument against the intervention of any but what are termed secondary causes, in the production of all the phenomena of the universe; that, in view of the intimate relations between Man and the rest of the living world; and between the forces exerted by the latter and all other forces, I can see no excuse for doubting that all are co-ordinated terms of Nature's great progression, from the formless to the formed-from the inorganic to the organic-from blind force to conscious intellect and will.

If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world.

Skepticism is the sadism of embittered souls.

Human vanity cherishes the absurd notion that our species is the final goal of evolution.

Such taxes [upon the necessaries of life], when they have grown up to a certain height, are a curse equal to the barrenness of the earth and the inclemency of the heavens; and yet it is in the richest and most industrious countries that they have been most generally imposed. No other countries could support so great a disorder.

Criticism actually says: You must free your I so completely from all limitations that it becomes a human I. I say: Free yourself as far as you can, and you have done your part; because it is not given to everyone to break through all limits, or, more eloquently: that is not a limit for everyone which is one to the others. Consequently, don't exhaust yourself on the limits of others; it's enough if you tear down your own. Who has ever been able to break down even one limit for all people? Aren't countless people today, as at all times, running around with all the "limitations of humanity"? One who overturns one of his limits may have shown others the way and the means; the overturning of their limits remains their affair.

Think not disdainfully of death, but look on it with favor; for even death is one of the things that Nature wills.

Virtue is debased by self-justification.

It is natural for us to seek a Standard of Taste; a rule, by which the various sentiments of men may be reconciled; at least, a decision, afforded, confirming one sentiment, and condemning another.

I did not direct my life. I didn't design it. I never made decisions. Things always came up and made them for me. That's what life is.

Though I myself am an atheist, I openly profess religion in the sense just mentioned, that is, a nature religion. I hate the idealism that wrenches man out of nature; I am not ashamed of my dependency on nature; I openly confess that the workings of nature affect not only my surface, my skin, my body, but also my core, my innermost being, that the air I breathe in bright weather has a salutary effect not only on my lungs but also on my mind, that the light of the sun illumines not only my eyes but also my spirit and my heart. And I do not, like a Christian, believe that such dependency is contrary to my true being or hope to be delivered from it. I know further that I am a finite moral being, that I shall one day cease to be. But I find this very natural and am therefore perfectly reconciled to the thought.

The virtue of frugality lies in a middle between avarice and profusion, of which the one consists in an excess, the other in a defect of the proper attention to the objects of self-interest.

Compared with the greatest poets, he may be said to be the poet of unpoetical natures, possessed of quiet and contemplative tastes. But unpoetical natures are precisely those which require poetic cultivation. This cultivation Wordsworth is much more fitted to give, than poets who are intrinsically far more poets than he.

It is a greatness not of mere body and gigantic bulk, but a rude greatness of soul. There is a sublime uncomplaining melancholy traceable in these old hearts. A great free glance into the very deeps of thought. They seem to have seen, these brave old Northmen, what Meditation has taught all men in all ages, That this world is after all but a show,-a phenomenon or appearance, no real thing. All deep souls see into that,-the Hindoo Mythologist, the German Philosopher,-the Shakspeare, the earnest Thinker, wherever he may be.

Here and everywhere is the struggle for existence, life inextricably enmeshed with war. All life living at the expense of life, every organism eating other organisms forever.

The defiance of established authority, religious and secular, social and political, as a world-wide phenomenon may well one day be accounted the outstanding event of the last decade.

Those who need myths are indeed poor. Here the gods serve as beds or resting places as the day races across the sky.

It is a great mortification to the vanity of man, that his utmost art and industry can never equal the meanest of nature's productions, either for beauty or value. Art is only the under-workman, and is employed to give a few strokes of embellishment to those pieces, which come from the hand of the master.

In this book we turn to the study of new patterns of energy arising from man's physical and psychic artifacts and social organizations. The only method for perceiving process and pattern is by inventory of effects obtained by the comparison and contrast of developing situations.

In life, in true life, there can be nothing better than what is. Wanting something different than what is, is blasphemy.

Undeterred by this examination, the French Revolution gave rise to ideas which led beyond the ideas of the entire old world order. The revolutionary movement which began in 1789 in the Cercle Social, which in the middle of its course had as its chief representatives Leclerc and Roux, and which finally with Babeuf's conspiracy was temporarily defeated, gave rise to the communist idea which Babeuf's friend Buonarroti re-introduced in France after the Revolution of 1830. This idea, consistently developed, is the idea of the new world order.

Hath God obliged himself not to exceed the bounds of our knowledge?

Life creates itself in delirium and is undone in ennui.

The faith that stands on authority is not faith.

Work is the grand cure for all the maladies and miseries that ever beset mankind,-honest work, which you intend getting done.

Art thy not content that thou hast done something conformable to thy nature, and dost thou seek to be paid for it? Just as if the eye demanded recompense for seeing, or the feet for walking. For as these members are formed for a particular purpose... so also is man formed by nature to acts of benevolence.

If it is the drive of our time, after freedom of thought is won, to pursue it to that perfection through which it changes to freedom of the will in order to realize the latter as the principle of a new era, then the final goal of education can no longer be knowledge, but the will born out of knowledge, and the spoken expression of that for which it has to strive is: the personal or free man. Truth consists in nothing other than man's revelation of himself, and thereto belongs the discovery of himself, the liberation from all that is alien, the uttermost abstraction or release from all authority, the re-won naturalness. Such thoroughly true men are not supplied by school; if they are there, they are there in spite of school.

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.

Fundamental ideas play the most essential role in forming a physical theory. Books on physics are full of complicated mathematical formulae. But thought and ideas, not formulae, are the beginning of every physical theory. The ideas must later take the mathematical form of a quantitative theory, to make possible the comparison with experiment.

The idea of universal human dignity ultimately comes out of Christianity... the view that all human beings are equal in the sight of God because they have the capacity for moral choice. As Western thought developed in the 17th-18th centuries, this took on a secular form under thinkers like Jean-Jacques Rousseau or Immanuel Kant or Georg Hegel, who argued that human equality is... based on human autonomy.

She with one breath attunes the spheres, And also my poor human heart.

I cannot contribute anything to this world because I only have one method: agony.

But by far the greatest hindrance and aberration of the human understanding proceeds from the dullness, incompetency, and deceptions of the senses; in that things which strike the sense outweigh things which do not immediately strike it, though they be more important. Hence it is that speculation commonly ceases where sight ceases; insomuch that of things invisible there is little or no observation.

This market way of life promotes addictions to stimulation and obsessions with comfort and convenience.

Justice is what love looks like in public.

In the most secret chamber of the spirit of him who believes himself convinced that death puts an end to his personal consciousness, his memory, for ever, and all unknown to him perhaps, there lurks a shadow, a vague shadow, a shadow of uncertainty, and while he says within himself, "Well, let us live this life that passes away, for there is no other!" the silence of this secret chamber speaks to him and murmurs, "Who knows!... " These voices are like the humming of a mosquito when the south-west wind roars through the trees in the wood; we cannot distinguish this faint humming, yet nevertheless, merged in the clamor of the storm, it reaches the ear.

A great fortune is a great slavery.

The supervision of the state extends to the lock upon the door, and there begins mine own. The lock is the boundary line between the power of the government and my own private power. It is the intention of locks to make possible self-protection. In my own house my person is sacred and inviolable even to the government. In civil cases government has no right to attack me in my house, but must wait till I am upon public ground.

Society can and does execute its own mandates: and if it issues wrong mandates instead of right, or any mandates at all in things with which it ought not to meddle, it practises a social tyranny more formidable than many kinds of political oppression, since, though not usually upheld by such extreme penalties, it leaves fewer means of escape, penetrating much more deeply into the details of life, and enslaving the soul itself. Protection, therefore, against the tyranny of the magistrate is not enough: there needs protection also against the tyranny of the prevailing opinion and feeling; against the tendency of society to impose, by other means than civil penalties, its own ideas and practices as rules of conduct on those who dissent from them; to fetter the development, and, if possible, prevent the formation, of any individuality not in harmony with its ways, and compel all characters to fashion themselves upon the model of its own.
