Living a minimally acceptable ethical life involves using a substantial part of our spare resources to make the world a better place. Living a fully ethical life involves doing the most good we can.

But your crime will be there, one hundred times denied, always there, dragging itself behind you. Then you will finally know that you have committed your life with one throw of the die, once and for all, and there is nothing you can do but tug our crime along until your death. Such is the law, just and unjust, of repentance. Then we will see what will become of your young pride.

When we reflect on the long and dense night in which France and all Europe have remained plunged by their governments and their priests, we must feel less surprise than grief at the bewilderment caused by the first burst of light that dispels the darkness.

He asked my religion and I replied 'agnostic'. He asked how to spell it, and remarked with a sigh: 'Well, there are many religions, but I suppose they all worship the same God. This remark kept me cheerful for about a week.

In many ways an artistic nature unfits a man for practical existence.

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.

My friends, I tell you that hitherto you have been prevented from even knowing what happiness really is, solely in consequence of the errors - gross errors - that have been combined with the fundamental notions of every religion that has hitherto been taught to men. And, in consequence, they have made man the most inconsistent, and the most miserable being in existence. By the errors of these systems he has been made a weak, imbecile animal; a furious bigot and fanatic or a miserable hypocrite; and should these qualities be carried, not only into the projected villages, but into Paradise itself, a Paradise would no longer be found!

Don Quixote made himself ridiculous; but did he know the most tragic ridicule of all, the inward ridicule, the ridiculousness of a man's self to himself, in the eyes of his own soul? Imagine Don Quixote's battlefield to be his own soul; imagine him to be fighting in his soul to save the Middle Ages from the Renaissance, to preserve the treasure of his infancy; imagine him an inward Don Quixote, with a Sancho at his side, inward and heroic too - and tell me if you find anything comic in the tragedy.

If you read history you will find that the Christians who did most for the present world were just those who thought most of the next... It is since Christians have largely ceased to think of the other world that they have become so ineffective in this. Aim at Heaven and you will get earth "thrown in": aim at earth and you will get neither.

The aged are cared for until death; adults are employed in jobs that make full use of their abilities; and children are nourished, educated, and fostered;...orphans... the disabled and the diseased are all well taken care of....

I consider one of the most important duties of any scientist the teaching of science to students and to the general public.

Ritual society is a society of rules. It is based not on virtues but on a passion for rules.

In its most general form, confinement was explained, or at least justified, by a will to avoid scandal. It thereby signalled an important change in the consciousness of evil. The Renaissance had let unreason in all its forms come out into the light of day, as public exposure gave evil the chance to redeem itself and to serve as an exemplum.

In art the Chinese aim at being exquisite, and in life at being reasonable.

By reducing any quality to quantity, myth economizes intelligence: it understands reality more cheaply.

He that works and does some Poem, not he that merely says one, is worthy of the name of Poet.

No regulation of commerce can increase the quantity of industry in any society beyond what its capital can maintain. It can only divert a part of it into a direction into which it might not otherwise have gone; and it is by no means certain that this artificial direction is likely to be more advantageous to the society than that into which it would have gone of its own accord. Every individual is continually exerting himself to find out the most advantageous employment for whatever capital he can command. It is his own advantage, indeed, and not that of the society, which he has in his view. But the study of his own advantage naturally, or rather necessarily leads him to prefer that employment which is most advantageous to the society.

The suffering man ought really 'to consume his own smoke'; there is no good in emitting smoke till you have made it into fire, - which, in the metaphorical sense too, all smoke is capable of becoming!

God's love for us is not the reason for which we should love him. God's love for us is the reason for us to love ourselves.

We all look for happiness, but without knowing where to find it: like drunkards who look for their house, knowing dimly that they have one.

"No man in this fashionable London of yours," friend Sauerteig would say, "speaks a plain word to me. Every man feels bound to be something more than plain; to be pungent withal, witty, ornamental. His poor fraction of sense has to be perked into some epigrammatic shape, that it may prick into me;-perhaps (this is the commonest) to be topsyturvied, left standing on its head, that I may remember it the better! Such grinning inanity is very sad to the soul of man. Human faces should not grin on one like masks; they should look on one like faces! I love honest laughter, as I do sunlight; but not dishonest: most kinds of dancing too; but the St.-Vitus kind not at all! A fashionable wit, ach Himmel, if you ask, Which, he or a Death's- head, will be the cheerier company for me? pray send not him!"

I well knew that to propose something which would be called extreme, was the true way not to impede but to facilitate a more moderate experiment.

The pint would call the quart a dualist, if you tried to pour the quart into him.

Power dements even more than it corrupts, lowering the guard of foresight and raising the haste of action.

Democracy is still upon its trial. The civic genius of our people is its only bulwark.

And at once I saw with great clarity that human beings possess two bodies. One is the physical body, the other -- just as real, just as self-contained -- is the emotional body. Like the physical body, the emotional body reaches a certain level of growth, and then stops. But it stops rather sooner than the physical body. So most of us possess the emotional body of a retarded adolescent.

[W]hen the ricochets of atomic billiards chance to put together an object that has a certain, seemingly innocent property, something momentous happens in the universe. That property is an ability to self-replicate; that is, the object is able to use the surrounding materials to make exact copies of itself, including replicas of such minor flaws in copying as may occasionally arise. What will follow from this singular occurrence, anywhere in the universe, is Darwinian selection and hence the baroque extravaganza that, on this planet, we call life. Never were so many facts explained by so few assumptions. Not only does the Darwinian theory command superabundant power to explain. Its economy in doing so has a sinewy elegance, a poetic beauty that outclasses even the most haunting of the world's origin myths. Preface

I believe government, organized authority, or the State is necessary only to maintain or protect property and monopoly. It has proven efficient in that function only. As a promoter of individual liberty, human well-being and social harmony, which alone constitute real order, government stands condemned by all the great men of the world...I believe - indeed, I know - that whatever is fine and beautiful in the human expresses and asserts itself in spite of government, and not because of it.

They sang the praises of nature, of the sea, of the woods. They liked making songs about one another, and praised each other like children; they were the simplest songs, but they sprang from their hearts and went to one's heart. And not only in their songs but in all their lives they seemed to do nothing but admire one another. It was like being in love with each other, but an all-embracing, universal feeling.

It happens that the stage sets collapse. Rising, streetcar, four hours in the office or the factory, meal, streetcar, four hours of work, meal, sleep and Monday Tuesday Wednesday Thursday Friday and Saturday according to the same rhythm this path is easily followed most of the time. But one day the "why" arises and everything begins in that weariness tinged with amazement.

Environments are not just containers, but are processes that change the content totally.

I opened with that which good Catholics have more than once made to Huguenots. "My dear sir," said I, "were you ever baptized?" "No, friend," replied the Quaker, "nor any of my brethren." "Zounds!" said I to him, "you are not Christians then!" "Friend," replied the old man, in a soft tone of voice, "do not swear; we are Christians, but we do not think that sprinkling a few drops of water on a child's head makes him a Christian." "My God!" exclaimed I, shocked at his impiety, "have you then forgotten that Christ was baptized by St. John?" "Friend," replied the mild Quaker, "once again, do not swear. Christ was baptized by John, but He Himself never baptized any one; now we profess ourselves disciples of Christ, and not of John." "Mercy on us," cried I, "what a fine subject you would be for the holy inquisitor! In the name of God, my good old man, let me baptize you."

A tragedy, then, is the imitation of an action that is serious and also, as having magnitude, complete in itself; in language ... not in a narrative form; with incidents arousing pity and fear, wherewith to accomplish its catharsis of such emotions.

Character is higher than intellect...A great soul will be strong to live, as well as strong to think.

I came into this world, not chiefly to make this a good place to live in, but to live in it, be it good or bad.

All wars today tend to be netwars.

I believe in clear-cut positions. I think that the most arrogant position is this apparent, multidisciplinary modesty of "what I am saying now is not unconditional, it is just a hypothesis," and so on. It really is a most arrogant position. I think that the only way to be honest and expose yourself to criticism is to state clearly and dogmatically where you are. You must take the risk and have a position.

Of this Shakspeare of ours, perhaps the opinion one sometimes hears a little idolatrously expressed is, in fact, the right one; I think the best judgement not of this country only, but of Europe at large, is slowly pointing to the conclusion, That Shakspeare is the chief of all Poets hitherto; the greatest intellect who, in our recorded world, has left record of himself in the way of Literature. On the whole, I know not such a power of vision, such a faculty of thought, if we take all the characters of it, in any other man. Such a calmness of depth; placid joyous strength; all things imaged in that great soul of his so true and clear, as in a tranquil unfathomable sea!

The strongest bulwark of authority is uniformity; the least divergence from it is the greatest crime. The wholesale mechanisation of modern life has increased uniformity a thousandfold. It is everywhere present, in habits, tastes, dress, thoughts and ideas. Its most concentrated dullness is "public opinion." Few have the courage to stand out against it. He who refuses to submit is at once labelled "queer," "different," and decried as a disturbing element in the comfortable stagnancy of modern life.

There can be no freedom in the large sense of the word, no harmonious development, so long as mercenary and commercial considerations play an important part in the determination of personal conduct.

You could give Aristotle a tutorial. And you could thrill him to the core of his being. Aristotle was an encyclopedic polymath, an all time intellect. Yet not only can you know more than him about the world, you also can have a deeper understanding of how everything works. Such is the privilege of living after Newton, Darwin, Einstein, Planck, Watson, Crick and their colleagues.

The mystery is that the world is at it is -- a mystery that is the source of all joy and all sorrow, of all hope and fear, and the source of development both creative and degenerative. The contingency of all into which time enters is the source of pathos, comedy, and tragedy.

As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power. You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about.

In conclusion, then, no satisfactory interpretation of quantum mechanics exists today. The questions posed by the confrontation between the Copenhagen interpretation and the hidden variable theorists go to the very foundations of microphysics, but the answers given by hidden variable theorists and Copenhagenists are alike unsatisfactory. Human curiosity will not rest until those questions are answered, but whether they will be answered by conceptual innovations within the framework of the present theory or only within the framework of an as yet unforeseen theory is unknown. The first step toward answering them has been attempted here. It is the modest but essential step of becoming clear on the nature and magnitude of the difficulties.

To revolt is a natural tendency of life. Even a worm turns against the foot that crushes it. In general, the vitality and relative dignity of an animal can be measured by the intensity of its instinct to revolt.

To one unnamed, whose name will one day be named, is dedicated, with this little work, the entire authorship, as it was from the beginning.

If slavery, barbarism and desolation are to be called peace, men can have no worse misfortune. No doubt there are usually more and sharper quarrels between parents and children, than between masters and slaves ; yet it advances not the art of household management to change a father's right into a right of property, and count children but as slaves. Slavery, then, and not peace, is furthered by handing the whole authority to one man.
