It was mathematics, the non-empirical science par excellence, wherein the mind appears to play only with itself, that turned out to be the science of sciences, delivering the key to those laws of nature and the universe that are concealed by appearances.

Monsieur ... I do not believe in God; his existence has been disproved by Science. But in the concentration camp, I learned to believe in men.

The essence of the modern state is the union of the universal with the full freedom of the particular, and with the welfare of individuals.

The Yin based its propriety on that of the Xia, and what it added and subtracted is knowable. The Zhou has based its propriety on that of the Shang and what it added and subtracted is knowable. In this way, what continues from the Chou, even if 100 generations hence, is knowable.

...it [is] possible to suppose that, if Russia is allowed to have peace, an amazing industrial development may take place, making Russia a rival of the United States.

It has been said that love robs those who have it of their wit, and gives it to those who have none.

I am sure, zeal or love for truth can never permit falsehood to be used in the defence of it.

I grasp at each second, trying to suck it dry: nothing happens which I do not seize, which I do not fix forever in myself, nothing, neither the fugitive tenderness of those lovely eyes, nor the noises of the street, nor the false dawn of early morning: and even so the minute passes and I do not hold it back, I like to see it pass.

If they drive God from the earth, we shall shelter Him underground.

As far as physicians go, chance is more valuable than knowledge.

To desire friendship is a great fault. Friendship should be a gratuitous joy like those afforded by art or life. We must refuse it so that we may be worthy to receive it; it is of the order of grace.

By 1204, the only place where the entire body of Greek learning existed, still intact, was Constantinople. As a result of the crusaders' conquest, however, Constantinople was ruthlessly pillaged and destroyed and almost all the great treasures of ancient Greek learning were lost forever. It is because of that sack, for instance, that we have only seven plays left out of the better than one hundred written by Sophocles. The tragedy of 1204 can never be undone and for all of time, only bits and pieces of the marvelous Greek world can be known to us.

A distant enemy is always preferable to one at the gate.

A handful of soldiers is always better than a mouthful of arguments.

I joke sometimes to the effect that when I approach a part of a book where I must explain something I don't understand, I just type faster and faster and faster. Then, when I get to the part I don't understand, sheer inertia pushes me through. That's not literally true, of course, but there's something to it psychologically.

Properly speaking, a man has as many social selves as there are individuals who recognise him.

...I pray to God to make me free of God.

What of a truth that is bounded by these mountains and is falsehood to the world that lives beyond?

Endless brooding over a question undermines you as much as a dull pain.

I write in a hurry, because the little one, who has been sleeping a long time, begins to call for me. Poor thing! when I am sad, I lament that all my affections grow on me, till they become too strong for my peace, though they all afford me snatches of exquisite enjoyment.

It is, I think, safe to say that nothing was more alien to the minds of the scientists, who brought about the most radical and most rapid revolutionary process the world has ever seen, than any will to power. Nothing was more remote than any wish to 'conquer space' and to go to the moon. It was indeed their search for 'true reality' that led them to lose confidence in appearances, in the phenomena as they reveal themselves of their own accord to human sense and reason. They were inspired by an extraordinary love of harmony and lawfulness which taught them that they would have to step outside any merely given sequence or series of occurrences if they wanted to discover the overall beauty and order of the whole, that is, the universe.

It is very important to note that some 2,500 years ago at the least Pythagoras went from Samos to the Ganges to learn geometry...But he would certainly not have undertaken such a strange journey had the reputation of the Brahmins' science not been long established in Europe...

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.

"Where do you get those superior airs of yours?" "I've managed to survive, you see, all those nights when I wondered: am I going to kill myself at dawn?"

Society triumphs over many. They wish to regenerate the world with their institutions, with their moral philosophy, with their love. Then they sink to living from breakfast till dinner, from dinner till tea, with a little worsted work, and to looking forward to nothing but bed. When shall we see a life full of steady enthusiasm, walking straight to its aim, flying home, as that bird is now, against the wind - with the calmness and the confidence of one who knows the laws of God and can apply them?

We all observe that the reality of sexual intercourse is far from perfect; yet this does not convince us that sex is a greatly overrated occupation. Every time a man glimpses a pretty girl pulling up her stocking, he catches a glimpse of what might be called the "primal sexual vision." It is unfortunate that there seems to be a certain disparity between this primal vision and most ordinary sexual experience. But it dances in front of us like a will-o'-the-wisp, luring us into tormented effort. It can lead novelists to write novels, poets to write poems, and musicians to write symphonies.

When speaking of the spiritual nature or the soul, we are referring to that which is "inner" or "new." When speaking of the bodily nature, or that which is flesh and blood, we are referring to that which is called "sensual," "outward," or "old." Paul writes in 2 Corinthians 4:16: "Even though our outer nature is wasting away, our inner nature is being renewed day by day."

Whenever our neighbour's house is on fire, it cannot be amiss for the engines to play a little on our own.

The Law of conservation of energy tells us we can't get something for nothing, but we refuse to believe it.

On reaching Athens he fell in with Antisthenes. Being repulsed by him, because he never welcomed pupils, by sheer persistence Diogenes wore him out. Once when he stretched out his staff against him, the pupil offered his head with the words, "Strike, for you will find no wood hard enough to keep me away from you, so long as I think you've something to say."

People travel to wonder at the height of mountains, at the huge waves of the sea, at the long courses of rivers, at the vast compass of the ocean, at the circular motion of the stars; and they pass by themselves without wondering.

Of the eternal corporeal substance (which is not producible ex nihilo, nor reducible ad nihilum, but rarefiable, condensable, formable, arrangeable, and "fashionable") the composition is dissolved, the complexion is changed, the figure is modified, the being is altered, the fortune is varied, only the elements remaining what they are in substance, that same principle persevering which was always the one material principle, which is the true substance of things, eternal, ingenerable and incorruptible.

Jehovah, Allah, the Trinity, Jesus, Buddha, are names for a great variety of human virtues, human mystical experiences, human remorses, human compensatory fantasies, human terrors, human cruelties. If all men were alike, all the world would worship the same God.

It is difficult for the isolated individual to work himself out of the immaturity which has become almost natural for him. He has even become fond of it and for the time being is incapable of employing his own intelligence, because he has never been allowed to make the attempt. Statutes and formulas, these mechanical tools of a serviceable use, or rather misuse, of his natural faculties, are the ankle-chains of a continuous immaturity. Whoever threw it off would make an uncertain jump over the smallest trench because he is not accustomed to such free movement. Therefore there are only a few who have pursued a firm path and have succeeded in escaping from immaturity by their own cultivation of the mind.

Consider MacArthur and his Republican supporters. So limited is his intelligence and his imagination that he is never puzzled for one moment. All we have to do is to go back to the days of the Opium War. After we have killed a sufficient number of millions of Chinese, the survivors among them will perceive our moral superiority and hail MacArthur as a saviour. But let us not be one-sided. Stalin, I should say, is equally simple- minded and equally out of date. He, too, believes that if his armies could occupy Britain and reduce us all to the economic level of Soviet peasants and the political level of convicts, we should hail him as a great deliverer and bless the day when we were freed from the shackles of democracy. One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision.

These terrible sociologists, who are the astrologers and alchemists of our twentieth century.

Whatever you would make habitual, practice it; and if you would not make a thing habitual, do not practice it, but accustom yourself to something else.

You have stolen my face from me: you know it and I no longer do.

The institutions of the Ruler are rooted in his own character and conduct, and sufficient attestation of them is given by the masses of the people. He examines them by comparison with those of the three kings, and finds them without mistake. He sets them up before Heaven and Earth, and finds nothing in them contrary to their mode of operation. He presents himself with them before spiritual beings, and no doubts about them arise. He is prepared to wait for the rise of a sage a hundred ages after, and has no misgivings. His presenting himself with his institutions before spiritual beings, without any doubts arising about them, shows that he knows Heaven. His being prepared, without any misgivings, to wait for the rise of a sage a hundred ages after, shows that he knows men.

Men can be provincial in time, as well as in place.

Often, writers on historical events tend to consider ... a loss of willingness to fight as a sign of "decadence," as though there were something despicable about not being a bully and not being willing to engage in mass murder. Perhaps we ought to feel instead that to cease to be warlike means to begin to be civilized and decent.

Insurrection ... never brings about the desired improvement. For insurrection lacks discernment; it generally harms the innocent more than the guilty. Hence, no insurrection is ever right, no matter how right the cause it seeks to promote.

The universe is composed of matter, and, as a system, is sustained by motion. Motion is not a property of matter, and without this motion the solar system could not exist. Were motion a property of matter, that undiscovered and undiscoverable thing, called perpetual motion, would establish itself. It is because motion is not a property of matter, that perpetual motion is an impossibility in the hand of every being, but that of the Creator of motion. When the pretenders to Atheism can produce perpetual motion, and not till then, they may expect to be credited.

It is not the same thing. You are perhaps not lying, but you are not telling the truth.

One of those leaders of what they call the social revolution has said that religion is the opiate of the people. Opium...opium...opium, yes. Let us give them opium so that they can sleep and dream.

What needs saying is worth saying twice.

The reaction against your own thought in itself lends life to thought. How this reaction is born is hard to describe, because it identifies with the very rare intellectual tragedies. - The tension, the degree and level of intensity of a thought proceeds from its internal antinomies, which in turn are derived from the unsolvable contradictions of a soul. Thought cannot solve the contradictions of the soul. As far as linear thinking is concerned, thoughts mirror themselves in other thoughts, instead of mirroring a destiny.

How it could come to pass I do not know, but I remember it clearly. The dream embraced thousands of years and left in me only a sense of the whole. I only know that I was the cause of their sin and downfall. Like a vile trichina, like a germ of the plague infecting whole kingdoms, so I contaminated all this earth, so happy and sinless before my coming. They learnt to lie, grew fond of lying, and discovered the charm of falsehood.

I was not the one to invent lies: they were created in a society divided by class and each of us inherited lies when we were born. It is not by refusing to lie that we will abolish lies: it is by eradicating class by any means necessary.

It is easy to see that this problem can be solved neither in theoretical nor in practical philosophy, but only in a higher discipline, which is the link that combines them, and neither theoretical nor practical, but both at once.
