If two men who were friends in their youth meet again when they are old, after being separated for a life-time, the chief feeling they will have at the sight of each other will be one of complete disappointment at life as a whole; because their thoughts will be carried back to that earlier time when life seemed so fair as it lay spread out before them in the rosy light of dawn, promised so much - and then performed so little.

Objection to scientific knowledge: this world doesn't deserve to be known.

All his life he [the American] jumps into the train after it has started and jumps out before it has stopped; and he never once gets left behind, or breaks a leg.

The metaphysical image that a definite epoch forges of the world has the same structure as what the world immediately understands to be appropriate as a form of its political organization.

The heroes in paganism correspond exactly to the saints in popery, and holy dervises in MAHOMETANISM. The place of, HERCULES, THESEUS, HECTOR, ROMULUS, is now supplied by DOMINIC, FRANCIS, ANTHONY, and BENEDICT. Instead of the destruction of monsters, the subduing of tyrants, the defence of our native country; whippings and fastings, cowardice and humility, abject submission and slavish obedience, are become the means of obtaining celestial honours among mankind.

Without consciousness there would, practically speaking, be no world, for the world exists as such only in so far as it is consciously reflected and considered by a psyche. Consciousness is a precondition of being.

But if one should guide his life by true principles, man's greatest riches is to live on a little with contented mind; for a little is never lacking.

Whenever a system of communication evolves, there is always the danger that some will exploit the system for their own ends.

Throughout history there have been peasant rebellions which have followed always the same course. Blindly, the peasants sacked and destroyed, and when members of the "upper classes" fell into their hands, they killed ruthlessly and cruelly, for never in their lives had they been taught gentleness and mercy by those now in their power.

Nothing made a happy slave, but a degraded man. In proportion as the mind grew callous to its degradation, and all sense of manly pride was lost, the slave felt comfort. In fact, he was no longer a man. If he were to define a man, he would say with Shakspeare,"Man is a being, holding large discourse,Looking before and after."A slave was incapable of either looking before or after.

Fanaticism consists in redoubling your efforts when you have forgotten your aim.

The world is but a perpetual see-saw.

Men have been released from concentration camps who have taken over the jargon of their jailers and with cold reason and mad consent (the price, as it were, of their survival) tell their story as if it could not have been otherwise than it was, contending that they have not been treated so badly after all.

The cucumber is bitter? Then throw it out. There are brambles in the path? Then go around them. That's all you need to know.

In the sphere of thought, absurdity and perversity remain the masters of the world, and their dominion is suspended only for brief periods.

The strongest of all warriors are these two - Time and Patience.

It cannot be denied that the early Indians possessed knowledge of God. All their writings are replete with sentiments and expressions, noble, clear, severely grand, as deeply conceived in any human language in which men have spoken of their God.

Human reason is by nature architectonic.

By far the most valuable things, which we know or can imagine, are certain states of consciousness, which may roughly be described as the pleasures of human intercourse and the enjoyment of beautiful objects. No one, probably, who has asked himself the question, has ever doubted that personal affection and the appreciation of what is beautiful in Art or Nature, are good in themselves; nor, if we consider strictly what things are worth having purely for their own sakes, does it appear probable that any one will think that anything else has nearly so much value as the things which are included under these two heads.

Christianity was an epidemic rather than a religion. It appealed to fear, hysteria and ignorance. It spread across the Western world, not because it was true, but because humans are gullible and superstitious.

The Book had in a high degree excited us to self-activity, which is the best effect of any book.

Never forget: We are alive within mysteries.

Who is not tempted by attractive and wide-awake children to join their sports, and crawl on all fours with them, and talk baby talk with them?

Religious beauty is superior to ideal beauty, since it is the ideal of the ideal.

The criminal law has, from the point of view of thwarted virtue, the merit of allowing an outlet for those impulses of aggression which cowardice, disguised as morality, restrains in their more spontaneous forms. War has the same merit. You must not kill you neighbor, whom perhaps you genuinely hate, but by a little propaganda this hate can be transferred to some foreign nation, against whom all your murderous impulses become patriotic heroism.

A book which, above all others in the world, should be forbidden, is a catalogue of forbidden books.

The philosophy of the soul of my people appears to me as an expression of an inward tragedy analogous to the tragedy of the soul of Don Quixote, as the expression of conflict between what the world is as scientific reason shows it to be and what we wish that it might be, as our religious faith affirms it to be. And in this philosophy is to be found the explanation of what is usually said about us - namely, that we are fundamentally irreducible to Kultur - or in other words, that we refuse to submit to it. No, Don Quixote does not resign himself either to the world, or to science or logic, or to art or esthetics, or to morality or ethics.

Power, like vanity, is insatiable. Nothing short of omnipotence could satisfy it completely. And as it is especially the vice of energetic men, the causal efficacy of love of power is out of all proportion to its frequency. It is, indeed, by far the strongest motive in the lives of important men. Love of power is greatly increased by the experience of power, and this applies to petty power as well as to that of potentates.

All metaphysical theories are inconclusively vulnerable to positivist attack.

Mucius put his hand into the fire. It is painful to be burned; but how much more painful to inflict such suffering upon oneself!

If there is something more excellent than the truth, then that is God; if not, then truth itself is God.

“What man among you with 100 sheep, on losing one of them, will not leave the 99 behind in the wilderness and go after the lost one until he finds it? And when he has found it, he puts it on his shoulders and rejoices. And when he gets home, he calls his friends and his neighbors together, saying to them, ‘Rejoice with me, for I have found my sheep that was lost.' I tell you that in the same way, there will be more joy in heaven over one sinner who repents than over 99 righteous ones who have no need of repentance.

You read the face of the sky and of the earth, but you have not recognized the one who is before you, and you do not know how to read this moment.

Justice is the first virtue of social institutions, as truth is of systems of thought. A theory however elegant and economical must be rejected or revised if it is untrue; likewise laws and institutions no matter how efficient and well-arranged must be reformed or abolished if they are unjust. Each person possesses an inviolability founded on justice that even the welfare of society as a whole cannot override. For this reason justice denies that the loss of freedom for some is made right by a greater good shared by others. It does not allow that the sacrifices imposed on a few are outweighed by the larger sum of advantages enjoyed by many. Therefore in a just society the liberties of equal citizenship are taken as settled; the rights secured by justice are not subject to political bargaining or to the calculus of social interests.

There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."

God, the supreme being, is neither circumscribed by space, nor touched by time; he cannot be found in a particular direction, and his essence cannot change. The secret conversation is thus entirely spiritual; it is a direct encounter between God and the soul, abstracted from all material constraints.

Tell me to what you pay attention and I will tell you who you are.

Something that is merely negative creates nothing.

He detested objective truths, the burden of argument, sustained reasoning. He disliked demonstrating, he wanted to convince no one. Others are a dialectician's invention.

This tendency towards a Christian-European Universal Monarchy has shown itself successively in the several States which could make pretensions to such a dominion, and, since the fall of the Papacy, it has become the sole animating principle of our History. We by no means seek to determine whether this notion of Universal Monarchy has ever been distinctly entertained as a definite plan .... Thus each State either strives to attain this Universal Christian Monarchy, or at least to acquire the power of striving after it;-to maintain the Balance of Power when it is in danger of being disturbed by another; and, in secret, for power, that it may eventually disturb it itself.

Conformity is an imitation of grace.

If the importation of foreign cattle, for example, were made ever so free, so few could be imported, that the grazing trade of Great Britain could be little affected by it. Live cattle are, perhaps, the only commodity of which the transportation is more expensive by sea than by land.

Man... whatever the origin of his soul, if it is pure, noble, and lofty, it is a beautiful soul which dignifies the man endowed with it.

The latest Gospel in this world is, Know thy work and do it. 'Know thyself:' long enough has that poor 'self' of thine tormented thee; thou wilt never get to 'know' it, I believe! Think it not thy business, this of knowing thyself; thou art an unknowable individual: know what thou canst work at; and work at it, like a Hercules! That will be thy better plan.

Cartan developed a general scheme of infinitesimal geometry in which Klein's notions were applied to the tangent plane and not to the n-dimensional manifold M itself. On the foundations of general infinitesimal geometry.

I wrote the books I should have liked to read. That's always been my reason for writing. People won't write the books I want, so I have to do it for myself.

The youth gets together his materials to build a bridge to the moon, or, perchance, a palace or temple on the earth, and, at length, the middle-aged man concludes to build a woodshed with them.
