Brief and powerless is Man's life; on him and all his race the slow, sure doom falls pitiless and dark.

I care little about the sword: I will allow a thing to struggle for itself in this world, with any sword or tongue or implement it has, or can lay hold of. We will let it preach, and pamphleteer, and fight, and to the uttermost bestir itself, and do, beak and claws, whatsoever is in it; very sure that it will, in the long-run, conquer nothing which does not deserve to be conquered. What is better than itself, it cannot put away, but only what is worse. In this great Duel, Nature herself is umpire, and can do no wrong: the thing which is deepest-rooted in Nature, what we call truest, that thing and not the other will be found growing at last.

The 'Logic of Induction' consists in stating the Facts and the Inference in such a manner, that the evidence of the Inference is manifest; just as the Logic of Deduction consists in stating the Premises and the Conclusion in such a manner that the Evidence of the Conclusion is manifest.

Temperament refers to the mode of reaction and is constitutional and not changeable; character is essentially formed by a person's experiences, especially of those in early life, and changeable, to some extent, by insights and new kinds of experiences. If a person has a choleric temperament, for instance, his mode of reaction is "quick and strong." But what he is quick or strong about depends on his kind of relatedness, his character. If he is a productive, just, loving person he will react quickly and strongly when he loves, when he is enraged by injustice, and when he is impressed by a new idea. If he is a destructive or sadistic character, he will be quick and strong in his destructiveness or in his cruelty. The confusion between temperament and character has had serious consequences for ethical theory. Preferences with regard to differences in temperament are mere matters of subjective taste. But differences in character are ethically of the most fundamental importance.

Science can only be comprehended epistemologically, which means as one category of possible knowledge, as long as knowledge is not equated either effusively with the absolute knowledge of a great philosophy or blindly with scientistic self-understanding of the actual business of research.

The cravings of love and sex are met with absolute ignorance by the majority of parents, who consider it as something indecent and improper, something disgraceful, almost criminal, to be suppressed and fought like some terrible disease. The love and tender feelings in the young plant are turned into vulgarity and coarseness through the stupidity of those surrounding it, so that everything fine and beautiful is either crushed altogether or hidden in the innermost depths, as a great sin, that dares not face the light.

Life is possible only by the deficiencies of our imagination and memory.

For consequentialists, of course, the imperative to imagine the consequences of living in a world in which everyone would act as you choose to act leads to the conclusion that some practices are utterly untenable, not because they are irrational, but because they inflict consequential damage that is unwanted. In both cases, I would suggest, a potential action is figured as hypothetically reciprocal: one's own act comes back in the imagined form of another's act; another might act on me as I would act on the other, and the consequences are unacceptable because of those damaging consequences.

To all this, someone is sure to object that life ought to subject itself to reason, to which we will reply that nobody ought to do what he is unable to do, and life cannot subject itself to reason. "Ought, therefore can," some Kantian will retort. To which we shall demur: "Cannot, therefore ought not." And life cannot submit itself to reason, because the end of life is living and not understanding.

It is no longer the moral, religious, spiritual condition of the people that is our concern, but their physical, practical, economical condition, as regulated by public laws.

Obsolescence is the moment of superabundance.

A physician, after he had felt the pulse of Pausanias, and considered his constitution, saying, "He ails nothing," "It is because, sir," he replied, "I use none of your physic."

A vague uncritical idealism always lends itself to ridicule and too much of it might be a danger to mankind, leading it round in a futile wild-goose chase for imaginary ideals.

One of the principal reasons that diverts those who are entering upon this knowledge so much from the true path which they should follow, is the fancy that they take at the outset that good things are inaccessible, giving them the name great, lofty, elevated, sublime. This destroys everything. I would call them low, common, familiar: these names suit it better; I hate such inflated expressions.

Even a single hair casts its shadow.

To speak frankly, the family bond in the civilizee regime' causes fathers to desire the death of their children and children to desire the death of their fathers.

My reason will still not understand why I pray, but I shall still pray, and my life, my whole life, independently of anything that may happen to me, is every moment of it no longer meaningless as it was before, but has an unquestionable meaning of goodness with which I have the power to invest it.

It has been observed that missiles and projectiles describe a curved path of some sort; however no one has pointed out the fact that this path is a parabola. But this and other facts, not few in number or less worth knowing, I have succeeded in proving; and what I consider more important, there have been opened up to this vast and most excellent science, of which my work is merely the beginning, ways and means by which other minds more acute than mine will explore its remote corners.

A single part of physics occupies the lives of many men, and often leaves them dying in uncertainty.

Persecution of powerless or power-losing groups may not be a very pleasant spectacle, but it does not spring from human meanness alone. What makes men obey or tolerate real power and, on the other hand, hate people who have wealth without power, is the rational instinct that power has a certain function and is of some general use. Even exploitation and oppression still make society work and establish some kind of order. Only wealth without power or aloofness without a policy are felt to be parasitical, useless, revolting, because such conditions cut all the threads which tie men together. Wealth which does not exploit lacks even the relationship which exists between exploiter and exploited; aloofness without policy does not imply even the minimum concern of the oppressor for the oppressed.

It pays to be obvious, especially if you have a reputation for subtlety.

All is ephemeral - fame and the famous as well.

The anger of lovers renews the strength of love.

We do not have a complete and satisfying knowledge of the world. We are reduced to the simple conclusion that everywhere in the world there is life like ourselves and that all life is shrouded in mystery. A true acquaintance with the world consists in being filled with a sense of the mystery of existence and life. This mystery becomes only more mysterious with every advance in scientific research. To be filled with the mystery of life is like that which is called in the language of mysticism the "wise ignorance," an ignorance which is nonetheless knowledge of the essential.

The distinction of Fact and Theory is only relative. Brute animals have a practical knowledge of relations of space and force; but they have no knowledge of Geometry or Mechanicks.

Modern man may assert that he can dispense with them, and he may bolster his opinion by insisting that there is no scientific evidence of their truth. But since we are dealing with invisible and unknowable things (for God is beyond human understanding, and there is no mean of proving immortality), why should we bother with evidence?

The centuries are thick, dark waves that rise and fall, steeped in blood. Every moment is a gaping abyss. Gaze on the dark sea without staggering, confront the abyss every moment without illusion or impudence or fear. ... But this is not enough; take a further step: battle to give meaning to the confused struggles of man.

Do not act as if thou wert going to live ten thousand years. Death hangs over thee. While thou livest, while it is in thy power, be good.

Antisthenes ... said once to a youth from Pontus who was on the point of coming to him to be his pupil, and was asking him what things he wanted, "You want a new book, and a new pen, and a new tablet;"

Thus, while the refugee serfs only wished to be free to develop and assert those conditions of existence which were already there, and hence, in the end, only arrived at free labour, the proletarians, if they are to assert themselves as individuals, will have to abolish the very condition of their existence hitherto (which has, moreover, been that of all society up to the present), namely, labour. Thus they find themselves directly opposed to the form in which, hitherto, the individuals, of which society consists, have given themselves collective expression, that is, the State. In order, therefore, to assert themselves as individuals, they must overthrow the State.

Whatever the virtue may be, from whatever source it may come, it is worthy of esteem... Mind, beauty, wealth, nobility, although the children of chance, all have their own value, as skill, learning and virtue have theirs.

If you let people follow their feelings, they will be able to do good. This is what is meant by saying that human nature is good.

In the face of the idea that truth might afford the opposite of satisfaction and turn out to be completely shocking to humanity at any given historical moment, ... the fathers of pragmatism made the satisfaction of the subject the criterion of truth. For such a doctrine there is no possibility of rejecting or even criticizing any species of belief that is enjoyed by its adherents.

Not without reason did he who had the right to do so speak of the foolishness of the cross. Foolishness, without a doubt, foolishness. And the American humorist, Oliver Wendell Holmes, was not altogether wide of the mark in making one of the characters in his ingenious conversations say that he thought better of those who were confined in a lunatic asylum on account of religious mania than of those who, while professing the same religious principles, kept their wits and appeared to enjoy life very well outside the asylums. But those who are at large, are they not really, thanks to God, mad too? Are there not mild madnesses, which not only permit us to mix with our neighbors without danger to society, but which rather enable us to do so, for by means of them we are able to attribute a meaning and finality to life and society?

Having destroyed the social power of the nobility and the guildmasters, the bourgeois also destroyed their political power. Having raised itself to the actual position of first class in society, it proclaims itself to be also the dominant political class. This it does through the introduction of the representative system which rests on bourgeois equality before the law and the recognition of free competition, and in European countries takes the form of constitutional monarchy. In these constitutional monarchies, only those who possess a certain capital are voters - that is to say, only members of the bourgeoisie. These bourgeois voters choose the deputies, and these bourgeois deputies, by using their right to refuse to vote taxes, choose a bourgeois government.

Thus did the Holy Harlots unhinge the brains of man,and when they met and clashed with the pure Mountain Maidens,they raised their white arms high, their armpits smelled of musk,and, as the rites decreed, both fought their verbal war:"God swoops from mountain peeks to eat and play on earth;we are his food and drink and even his sacred toys -and learn, O sterile maids, we are his soft, sweet mates.Let her now leave who fears to merge with her dread God!"The scornful savage mouth of Krino flashed reply:"We will not leave! We guard the innocent soul of man!God is a spirit with pure white wings, a soul that sails,light, disembodied, deep in our thoughts, without embrace.It's we who keep the world in bloom with virgin souls!"

Since those who rule in the city do so because they own a lot, I suppose they're unwilling to enact laws to prevent young people who've had no discipline from spending and wasting their wealth, so that by making loans to them, secured by the young people's property, and then calling those loans in, they themselves become even richer and more honored.

But our Don Quixote, the inward, the immortal Don Quixote, conscious of his own comicness, does not believe that his doctrines will triumph in this world, because they are not of it. And it is better that they should not triumph. And if the world wished to make Don Quixote king, he would retire alone to the mountain, fleeing from the king-making crowds, as Christ retired alone to the mountain when, after the miracle of the loaves and fishes, they sought to proclaim him king. He left the title of king for the inscription written over the cross.

But what we've got going wrong is we've got a kind of bifurcation in cultural development:You take your classified telephone directory, and open up "Churches", and have a ruler in your hand. And you will find that the longest space is occupied by authoritarian, Bible-banging churches. And these people are barbarians, who take the written word of the Bible literally. Because they need terribly, they have a personal need, for something to depend on. ... The government realizes that there is a very large number of people like that; and therefore, to keep their votes, they have to pander to those kind of people. And these are the boys who never grew up; they always need Papa. ... The trouble is that the boys who need Papa, are violent. They have the guns. And they are the types of people who like to be soldiers, policemen-tough guys. And therefore they have a great deal of power.

A young man should serve his parents at home and be respectful to elders outside his home. He should be earnest and truthful, loving all, but become intimate with humaneness. After doing this, if he has energy to spare, he can study literature and the arts.

Compared with the life-span of a human being the time-span of a civilization is so vast that a human observer cannot hope to take the measure of its curve unless he is in a position to view it in a distant perspective; and he can only obtain this perspective vis-a-vis some society that is extinct. He can never stand back sufficiently far from the history of the society in which he himself lives and moves and has his being. In other words, to assert of any living society, at any moment in its life, that it is the consummation of human history is to hazard a guess which is intrinsically unsusceptible of immediate verification. When we find that a majority of the members of all societies at all times make this assertion about their own civilizations, it becomes evident that their guesses have really nothing to do with any objective calculation of probabilities but are pure expressions of the egocentric illusion.

It is not that we have a short space of time, but that we waste much of it. Life is long enough.

If good music has charms to soothe the savage breast, bad music has no less powerful spells for filling the mildest breast with rage, the happiest with horror and disgust. Oh, those mammy songs, those love longings, those loud hilarities! How was it possible that human emotions intrinsically decent could be so ignobly parodied.

Most kings and priests have been despotic, and all religions have been riddled with superstition.

Friendship ... flourishes not so much by kindnesses as by sincerity.

It's misleading to suppose there's any basic difference between education & entertainment. This distinction merely relieves people of the responsibility of looking into the matter.

We never know, believe me, when we have succeeded best.

Nature flies from the infinite, for the infinite is unending or imperfect, and Nature ever seeks an end.
