The great extension of our experience in recent years has brought light to the insufficiency of our simple mechanical conceptions and, as a consequence, has shaken the foundation on which the customary interpretation of observation was based.

Truth and clarity are complementary.

Every valuable human being must be a radical and a rebel, for what he must aim at is to make things better than they are.

Isolated material particles are abstractions, their properties being definable and observable only through their interaction with other systems.

It is not enough to be wrong, one must also be polite.

How wonderful that we have met with a paradox. Now we have some hope of making progress.

What is it that we humans depend on? We depend on our words... Our task is to communicate experience and ideas to others. We must strive continually to extend the scope of our description, but in such a way that our messages do not thereby lose their objective or unambiguous character ... We are suspended in language in such a way that we cannot say what is up and what is down. The word "reality" is also a word, a word which we must learn to use correctly.

Never express yourself more clearly than you are able to think.

Those who are not shocked when they first come across quantum theory cannot possibly have understood it.

Every sentence I utter must be understood not as an affirmation, but as a question.

For a parallel to the lesson of atomic theory regarding the limited applicability of such customary idealizations, we must in fact turn to quite other branches of science, such as psychology, or even to that kind of epistemological problems with which already thinkers like Buddha and Lao Tzu have been confronted, when trying to harmonize our position as spectators and actors in the great drama of existence.

I go into the Upanishads to ask questions.

We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.

It is a great pity that human beings cannot find all of their satisfaction in scientific contemplativeness.

However far the phenomena transcend the scope of classical physical explanation, the account of all evidence must be expressed in classical terms. The argument is that simply by the word "experiment" we refer to a situation where we can tell others what we have done and what we have learned and that, therefore, the account of the experimental arrangement and of the results of the observations must be expressed in unambiguous language with suitable application of the terminology of classical physics.

No, no, you are not thinking, you are just being logical.

The grand discoveries which scientific experiment yielded at and about the turn of the century, in which investigators in many countries took an eminent part and which were destined all unexpectedly to give us a fresh insight into the structure of atoms, were due in the first instance, as all are aware, to the work of the great investigators of the English school, Sir Joseph Thomson and Sir Ernest Rutherford, who have inscribed their names on the tablets of the history of scientific research as distinguished witnesses to the truth that imagination and acumen are capable of penetrating the crowded mass of registered experience and of revealing Nature's simplicity to our gaze.

Anyone who is not shocked by quantum theory has not understood it.

An expert is a person who has found out by his own painful experience all the mistakes that one can make in a very narrow field.

I am absolutely prepared to talk about the spiritual life of an electronic computer: to state that it is reflecting or is in a bad mood... The question whether the machine really feels or ponders, or whether it merely looks as though it did, is of course absolutely meaningingless.

Even the mathematical framework helps nothing, I would first like to understand how Nature avoids the contradictions.

Some subjects are so serious that one can only joke about them.

Universal love is really the way of the sage-kings. It is what gives peace to the rulers and sustenance to the people. The gentleman would do well to understand and practise universal love; then he would be gracious as a ruler, loyal as a minister, affectionate as a father, filial as a son, courteous as an elder brother, and respectful as a younger brother. So, if the gentleman desires to be a gracious ruler, a loyal minister, an affectionate father, a filial son, a courteous elder brother, and a respectful younger brother, universal love must be practised. It is the way of the sage-kings and the great blessing of the people.

If the rulers sincerely desire the empire to be wealthy and dislike to have it poor, desire to have it orderly and dislike to have it chaotic, they should bring about universal love and mutual aid. This is the way of the sage-kings and the way to order for the world, and it should not be neglected.

The wise man who has charge of governing the empire should know the cause of disorder before he can put it in order. Unless he knows its cause, he cannot regulate it.

The murder of one person is called unrighteous and incurs one death penalty. Following this argument, the murder of ten persons will be ten times as unrighteous and there should be ten death penalties; the murder of a hundred persons will be a hundred times as unrighteous and there should be a hundred death penalties. All the gentlemen of the world know that they should condemn these things, calling them unrighteous. But when it comes to the great unrighteousness of attacking states, they do not know that they should condemn it. On the contrary, they applaud it, calling it righteous.

If we should classify one by one all those who hate others and injure others, should we find them to be universal in love or partial? Of course we should say they are partial. Now, since partiality against one another is the cause of the major calamities in the empire, then partiality is wrong.

Suppose we try to locate the cause of disorder, we shall find it lies in the want of mutual love.

What is the purpose of houses? It is to protect us from the wind and cold of winter, the heat and rain of summer, and to keep out robbers and thieves. Once these ends have been secured, that is all. Whatever does not contribute to these ends should be eliminated.

If one does not preserve the learned in a state he will be injuring the state; if one is not zealous (to recommend) the virtuous upon seeing one, he will be neglecting the ruler. Enthusiasm is to be shown only to the virtuous, and plans for the country are only to be shared with the learned. Few are those, who, neglecting the virtuous and slighting the learned, could still maintain the existence of their countries. Book 1; Befriending the Learned Variant translation: To enter upon rulership of a country but not preserve its scholars will result in the downfall of the country. To see the worthy but not hasten to them will make the country's ruler less able to perform his duties. To the unworthy is due no attention. The ignorant should remain without inclusion in the state's affairs. To impede the virtuous and neglect the scholarly and still maintain the survival of the state has yet to be, indeed.

Whoever criticizes others must have something to replace them. Criticism without suggestion is like trying to stop flood with flood and put out fire with fire. It will surely be without worth.

If every one in the world will love universally; states not attacking one another; houses not disturbing one another; thieves and robbers becoming extinct; emperor and ministers, fathers and sons, all being affectionate and filial -- if all this comes to pass the world will be orderly. Therefore, how can the wise man who has charge of governing the empire fail to restrain hate and encourage love? So, when there is universal love in the world it will be orderly, and when there is mutual hate in the world it will be disorderly.

To accomplish anything whatsoever one must have standards. None have yet accomplished anything without them.

When we come to think about the several benefits in regard to their cause, how have they arisen? Have they arisen out of hate of others and injuring others? Of course we should say no. We should say they have arisen out of love of others and benefiting others. If we should classify one by one all those who love others and benefit others, should we find them to be partial or universal? Of course we should say they are universal. Now, since universal love is the cause of the major benefits in the world, therefore Mozi proclaims universal love is right. And, as has already been said, the interest of the magnanimous lies in procuring benefits for the world and eliminating its calamities. Now that we have found out the consequences of universal love to be the major benefits of the world and the consequences of partiality to be the major calamities in the world; this is the reason why Mozi said partiality is wrong and universality is right.

The purpose of the magnanimous is to be found in procuring benefits for the world and eliminating its calamities. ... Mutual attacks among states, mutual usurpation among houses, mutual injuries among individuals; the lack of grace and loyalty between ruler and ruled, the lack of affection and filial piety between father and son, the lack of harmony between elder and younger brothers - these are the major calamities in the world.

All states in the world, large or small, are cities of Heaven, and all people, young or old, honourable or humble, are its subjects; for they all graze oxen and sheep, feed dogs and pigs, and prepare clean wine and cakes to sacrifice to Heaven. Does this not mean that Heaven claims all and accepts offerings from all? Since Heaven does claim all and accepts offerings from all, what then can make us say that it does not desire men to love and benefit one another? Hence those who love and benefit others Heaven will bless. Those who hate and harm others Heaven will curse, for it is said that he who murders the innocent will be visited by misfortune. How else can we explain the fact that men, murdering each other, will be cursed by Heaven? Thus we are certain that Heaven desires to have men love and benefit one another and abominates to have them hate and harm one another.

When we try to develop and procure benefits for the world with universal love as our standard, then attentive ears and keen eyes will respond in service to one another, then limbs will be strengthened to work for one another, and those who know the Tao will untiringly instruct others. Thus the old and those who have neither wife nor children will have the support and supply to spend their old age with, and the young and weak and orphans will have the care and admonition to grow up in. When universal love is adopted as the standard, then such are the consequent benefits. It is incomprehensible, then, why people should object to universal love when they hear it.

When nobody in the world loves any other, naturally the strong will overpower the weak, the many will oppress the few, the wealthy will mock the poor, the honoured will disdain the humble, the cunning will deceive the simple. Therefore all the calamities, strifes, complaints, and hatred in the world have arisen out of want of mutual love. Therefore the benevolent disapproved of this want.

The words of malicious slander should not be allowed to enter the ear. A defensive voice should not be allowed to come out of the mouth. The want to gravely injure people should not be allowed to exist in the heart. If this is accomplished, though there be people who cynically expose others, they would be without people who would align with them.

Now, as to universal love and mutual aid, they are beneficial and easy beyond a doubt. It seems to me that the only trouble is that there is no superior who encourages it. If there is a superior who encourages it, promoting it with rewards and commendations, threatening its reverse with punishments, I feel people will tend toward universal love and mutual aid like fire tending upward and water downwards - it will be unpreventable in the world.

When feudal lords love one another there will be no more war; when heads of houses love one another there will be no more mutual usurpation; when individuals love one another there will be no more mutual injury. When ruler and ruled love each other they will be gracious and loyal; when father and son love each other they will be affectionate and filial; when older and younger brothers love each other they will be harmonious. When all the people in the world love one another, then the strong will not overpower the weak, the many will not oppress the few, the wealthy will not mock the poor, the honoured will not disdain the humble, and the cunning will not deceive the simple. And it is all due to mutual love that calamities, strife, complaints, and hatred are prevented from arising. Therefore the benevolent exalt it.

The virtuous who are prosperous must be exalted, and the virtuous who are not prosperous must be exalted too.

Such religion as there can be in modern life, every individual will have to salvage from the churches for himself.

I feel, like all modern Americans, no consciousness of sin and simply do not believe in it. All I know is that if God loves me only half as much as my mother does, he will not send me to Hell. That is a final fact of my inner consciousness, and for no religion could I deny its truth.

By association with nature's enormities, a man's heart may truly grow big also. There is a way of looking upon a landscape as a moving picture and being satisfied with nothing less big as a moving picture, a way of looking upon tropic clouds over the horizon as the backdrop of a stage and being satisfied with nothing less big as a backdrop, a way of looking upon the mountain forests as a private garden and being satisfied with nothing less as a private garden, a way of listening to the roaring waves as a concert and being satisfied with nothing less as a concert, and a way of looking upon the mountain breeze as an air-cooling system and being satisfied with nothing less as an air-cooling system. So do we become big, even as the earth and firmaments are big.

When the mirror meets with an ugly woman, when a rare ink-stone finds a vulgar owner, and when a good sword is in the hands of a common general, there is utterly nothing to be done about it.

A good traveler is one who does not know where he is going to, and a perfect traveler does not know where he came from.

The wise man reads both books and life itself.

There are two kinds of animals on earth. One kind minds his own business, the other minds other people's business. The former are vegetarians, like cows, sheep and thinking men. The latter are carnivorous, like hawks, tigers and men of action.

No, the enjoyment of an idle life doesn't cost any money. The capacity for true enjoyment of idleness is lost in the moneyed class and can be found only among people who have a supreme contempt for wealth. It must come from an inner richness of the soul in a man who loves the simple ways of life and who is somewhat impatient with the business of making money.
