Even purely intellectual progress brings about its revenges. Problems settled in a rough and ready way by rude men, absorbed in action, demand renewed attention and show themselves to be still unread riddles when men have time to think. The beneficent demon, doubt, whose name is Legion and who dwells amongst the tombs of old faiths, enters into mankind and thenceforth refuses to be cast out. Sacred customs, venerable dooms of ancestral wisdom, hallowed by tradition and professing to hold good for all time, are put to the question. Cultured reflection asks for their credentials; judges them by its own standards; finally, gathers those of which it approves into ethical systems, in which the reasoning is rarely much more than a decent pretext for the adoption of foregone conclusions.

The supreme task of the physicist is to arrive at those universal elementary laws from which the cosmos can be built up by pure deduction. There is no logical path to these laws; only intuition, resting on sympathetic understanding of experience, can reach them. In this methodological uncertainty, one might suppose that there were any number of possible systems of theoretical physics all equally well justified; and this opinion is no doubt correct, theoretically. But the development of physics has shown that at any given moment, out of all conceivable constructions, a single one has always proved itself decidedly superior to all the rest.

I saw a moving sight the other morning before breakfast in a little hotel where I slept in the dusty fields. The young man of the house shot a little wolf called coyote in the early morning. The little heroic animal lay on the ground, with his big furry ears, and his clean white teeth, and his little cheerful body, but his little brave life was gone. It made me think how brave all living things are. Here little coyote was, without any clothes or house or books or anything, with nothing to pay his way with, and risking his life so cheerfully - and losing it - just to see if he could pick up a meal near the hotel. He was doing his coyote-business like a hero, and you must do your boy-business, and I my man-business bravely, too, or else we won't be worth as much as a little coyote.

Any loss of identity prompts people to seek reassurance and rediscovery of themselves by testing, and even by violence. Today, the electric revolution, the wired planet, and the information environment involve everybody in everybody to the point of individual extinction.

After silence that which comes nearest to expressing the inexpressible is music.

The world becomes full of organisms that have what it takes to become ancestors. That, in a sentence, is Darwinism.

If everything must have a cause, then God must have a cause. If there can be anything without a cause, it may just as well be the world as God, so that there cannot be any validity in that argument. It is exactly of the same nature as the Hindu's view, that the world rested upon an elephant and the elephant rested upon a tortoise; and when they said, "How about the tortoise?" the Indian said, "Suppose we change the subject." The argument is really no better than that.

Nothing is harder to understand than a symbolic work. A symbol always transcends the one who makes use of it and makes him say in reality more than he is aware of expressing.

He who is running a race ought to endeavor and strive to the utmost of his ability to come off victor; but it is utterly wrong for him to trip up his competitor, or to push him aside. So in life it is not unfair for one to seek for himself what may accrue to his benefit; but it is not right to take it from another.

Subjective reason ... is inclined to abandon the fight with religion by setting up two different brackets, one for science and philosophy, and one for institutionalized mythology, thus recognizing both of them. For the philosophy of objective reason there is no such way out. Since it hold to the concept of objective truth, it must take a positive or a negative stand with regard to the content of established religion.

Of the twenty-two civilizations that appear in history, nineteen of them collapsed when they reached the moral state the United States is in now. The average age of the world's great civilizations has been 200 years. All nations have progressed through this sequence:From bondage to spiritual faithFrom spiritual faith to great courageFrom courage to libertyFrom liberty to abundanceFrom abundance to selfishnessFrom selfishness to complacencyFrom complacency to apathyFrom apathy to dependencyFrom dependency back again into bondage.

What is the Jew?...What kind of unique creature is this whom all the rulers of all the nations of the world have disgraced and crushed and expelled and destroyed; persecuted, burned and drowned, and who, despite their anger and their fury, continues to live and to flourish. What is this Jew whom they have never succeeded in enticing with all the enticements in the world, whose oppressors and persecutors only suggested that he deny (and disown) his religion and cast aside the faithfulness of his ancestors?! The Jew - is the symbol of eternity. ... He is the one who for so long had guarded the prophetic message and transmitted it to all mankind. A people such as this can never disappear. The Jew is eternal. He is the embodiment of eternity.

Animal Liberation is Human Liberation too.

The only justification for our concepts and system of concepts is that they serve to represent the complex of our experiences; beyond this they have no legitimacy. I am convinced that the philosophers have had a harmful effect upon the progress of scientific thinking in removing certain fundamental concepts from the domain of empiricism, where they are under our control, to the intangible heights of the a priori. For even if it should appear that the universe of ideas cannot be deduced from experience by logical means, but is, in a sense, a creation of the human mind, without which no science is possible, nevertheless the universe of ideas is just as little independent of the nature of our experience as clothes are of the form of the human body. This is particularly true of our concepts of time and space, which physicists have been obliged by the facts to bring down from the Olympus of the a priori in order to adjust them and put them in a serviceable condition.

Whatever can be done another day can be done today.

There certainly is self division. The man who watches a woman undressing has the red eyes of an ape; yet the man who sees two young lovers, really alone for the first time, who brings out all the pathos, the tenderness and uncertainty when he tells about it, is no brute; he is very much human. And the ape and the man exist in one body; and when the ape's desires are about to be fulfilled, he disappears and is succeeded by the man, who is disgusted with the ape's appetite.

The chief error in philosophy is overstatement.

Who loves not woman, wine, and song / Remains a fool his whole life long.

Appearances to the mind are of four kinds. Things either are what they appear to be; or they neither are, nor appear to be; or they are, and do not appear to be; or they are not, and yet appear to be. Rightly to aim in all these cases is the wise man's task.

I see myself immersed in the depths of human existence and standing in the face of the ineffable mystery of the world and of all that is. And in that situation, I am made poignantly and burningly aware that the world cannot be self-sufficient, that there is hidden in some still greater depth a mysterious, transcendent meaning. This meaning is called God. Men have not been able to find a loftier name, although they have abused it to the extent of making it almost unutterable. God can be denied only on the surface; but he cannot be denied where human experience reaches down beneath the surface of flat, vapid, commonplace existence.

The intelligence required for the solving of social problems is not a thing of the mere intellect. It must be animated with the religious sentiment and warm with sympathy for human suffering. It must stretch out beyond self-interest, whether it be the self-interest of the few or of the many. It must seek justice. For at the bottom of every social problem we will find a social wrong.

We know very well that we are only allowed to go on eating our dinner, to finish seeing the new play, or to enjoy to the end the ball, the Christmas fete, the promenade, the races or, the hunt, thanks to the policeman's revolver or the soldier's rifle, which will shoot down the famished outcast who has been robbed of his share, and who looks round the corner with covetous eyes at our pleasures, ready to interrupt them instantly, were not policeman and soldier there prepared to run up at our first call for help.

But that which is useful is the better.

Intuitionism is not constructive, perfectionism is unacceptable.

Love one another. My final lesson of history is the same as that of Jesus. You may think that's a lot of lollipop but just try it. Love is the most practical thing in the world. If you take an attitude of love toward everybody you meet, you'll eventually get along. When asked, at the age of 92, if he could summarize the lessons of history into a single sentence.

We do not have to love one another to be obligated to build a world in which all lives are sustainable. The right to persist can only be understood as a social right, as the subjective instance of a social and global obligation we bear toward one another.

The cause of anger is the belief that we are injured; this belief, therefore, should not be lightly entertained. We ought not to fly into a rage even when the injury appears to be open and distinct: for some false things bear the semblance of truth. We should always allow some time to elapse, for time discloses the truth.

It is not because men's desires are strong that they act ill; it is because their consciences are weak.

It has been said a thousand times and in a thousand books that ancestor-worship is for the most part the source of primitive religions, and it may be strictly said that what most distinguishes man from the other animals is that, in one form or another, he guards his dead and does not give them over to the neglect of teeming mother earth; he is an animal that guards its dead.

I hold the brimming wineglass and relive the toils of my grandfathers and great-grandfathers. The sweat of my labor runs down like a fountain from my tall, intoxicated brow. I am a sack filled with meat and bones, blood, sweat, and tears, desires and visions.

The truth is always in the minority, and the minority is always stronger than the majority, because as a rule the minority is made up of those who actually have an opinion, while the strength of the majority is illusory, formed of that crowd which has no opinion - and which therefore the next moment (when it becomes clear that the minority is the stronger) adopts the latter's opinion, which now is in the majority, i.e. becomes rubbish by having the whole retinue and numerousness on its side, while the truth is again in a new minority.

Children are nowhere taught, in any systematic way, to distinguish true from false, or meaningful from meaningless, statements. Why is this so? Because their elders, even in the democratic countries, do not want them to be given this kind of education.

Need and struggle are what excite and inspire us; our hour of triumph is what brings the void. Not the Jews of the captivity, but those of the days of Solomon's glory are those from whom the pessimistic utterances in our Bible come.

The will is a unity of two different aspects or moments: first, the individual's ability to abstract from every specific condition and, by negating it, to return to the absolute liberty of the pure ego; secondly, the individual's act of freely adopting a concrete condition, freely affirming his existence as a particular, limited ego.

However intimate we may be with the operations of the mind, we cannot think more than two or three minutes a day; - unless, by taste or by profession, we practice, for hours on end, brutalizing words in order to extract ideas from them. The intellectual represents the major disgrace, the culminating failure of Homo sapiens.

The man whom Nature has appointed to do great things is, first of all, furnished with that openness to Nature which renders him incapable of being insincere! To his large, open, deep-feeling heart Nature is a Fact: all hearsay is hearsay; the unspeakable greatness of this Mystery of Life, let him acknowledge it or not, nay even though he seem to forget it or deny it, is ever present to him,-fearful and wonderful, on this hand and on that.

There is no correlation between material and spiritual misery. Only to the lowest and dullest levels of society can one preach the formula for all human happiness and wholeness as the well-named "animal ideal," a well-being that is little better than bovine. Hegel rightly wrote that the epochs of material well-being are blank pages in the history book, and Toynbee has shown that the challenge to mankind of environmentally and spiritually harsh and problematic conditions is often the incentive that awakens the creative energies of civilization. In some cases, it is not paradoxical to say that the man of good will should try to make life difficult for his neighbor! It is a commonplace that all the higher virtues attenuate and atrophy under easy conditions, when man is not forced to prove himself in some way; and in the final analysis it does not matter in such situations if a good number fall away and are lost through natural selection.

Don't say: "They must have something in common, or they would not be called 'games'" but look and see whether there is anything common to all. For if you look at them, you won't see something that is common to all, but similarities, affinities, and a whole series of them at that.

Receive an injury rather than do one.

Accordingly, time logically supposes a continuous range of intensity of feeling. It follows then, from the definition of continuity, that when any particular kind of feeling is present, an infinitesimal continuum of all feelings differing infinitesimally from that, is present.

Our feeling about every obligation depends in each case upon the spirit in which the benefit is conferred; we weigh not the bulk of the gift, but the quality of the good-will which prompted it.

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.

In the highest civilization, the book is still the highest delight. He who has once known its satisfactions is provided with a resource against calamity.

Now, to say that a lot of objects is finite, is the same as to say that if we pass through the class from one to another we shall necessarily come round to one of those individuals already passed; that is, if every one of the lot is in any one-to-one relation to one of the lot, then to every one of the lot some one is in this same relation.
