The transition from Hegel to Marx is, in all respects, a transition to an essentially different order of truth, no to be interpreted in terms of philosophy. We shall see that all the philosophical concepts of Marxian theory are social and economic categories, whereas Hegel's social and economic categories are all philosophical concepts.

Science is a systematic method for studying and working out those generalizations that seem to describe the behavior of the universe. It could exist as a purely intellectual game that would never affect the practical life of human beings either for good or evil, and that was very nearly the case in ancient Greece, for instance. Technology is the application of scientific findings to the tools of everyday life, and that application can be wise or unwise, useful or harmful. Very often, those who govern technological decisions are not scientists and know little about science.

Tis from the resemblance of the external actions of animals to those we ourselves perform, that we judge their internal likewise to resemble ours; and the same principle of reasoning, carry'd one step farther, will make us conclude that since our internal actions resemble each other, the causes, from which they are deriv'd, must also be resembling.

So long as a man's power, that is, his capacity to realize what he has in mind, is bound to the goal, to the work, to the calling, it is, considered in itself, neither good nor evil, it is only a suitable or unsuitable instrument. But as soon as this bond with the goal is broken off or loosened, and the man ceases to think of power as the capacity to do something, but thinks of it as a possession, that is, thinks of power in itself, then his power, being cut off and self-satisfied, is evil; it is power withdrawn from responsibility, power which betrays the spirit, power in itself.

This great increase of the quantity of work which, in consequence of the division of labour, the same number of people are capable of performing, is owing to three different circumstances; first, to the increase of dexterity in every particular workman; secondly, to the saving of the time which is commonly lost in passing from one species of work to another; and lastly, to the invention of a great number of machines which facilitate and abridge labour, and enable one man to do the work of many.

The ancient Romans built their greatest masterpieces of architecture for wild beasts to fight in.

A penny saved is of more value than a penny paid out.

We need not suppose that when po+B40wer resides in an exclusive class, that class will knowingly and deliberately sacrifice the other classes to themselves: it suffices that, in the absence of its natural defenders, the interest of the excluded is always in danger of being overlooked: and, when looked at, is seen with very different eyes from those of the persons whom it directly concerns.

The most perfect ape cannot draw an ape; only man can do that; but, likewise, only man regards the ability to do this as a sign of superiority.

Anarchism, more than any other social theory, values human life above things.

The way of Heaven and Earth may be completely declared in one sentence: They are without any doubleness, and so they produce things in a manner that is unfathomable.

To understand a science it is necessary to know its history.

Hegel made famous his aphorism that all the rational is real and all the real rational; but there are many of us who, unconvinced by Hegel, continue to believe that the real, the really real, is irrational, that reason builds upon irrationalities. Hegel, a great framer of definitions, attempted with definitions to reconstruct the universe, like that artillery sergeant who said that cannon were made by taking a hole and enclosing it with steel.

Equity knows no difference of sex. In its vocabulary the word man must be understood in a generic, and not in a specific sense.

If anything extraordinary seems to have happened, we can always say that we have been the victims of an illusion. If we hold a philosophy which excludes the supernatural, this is what we always shall say.

The full expression of personality depends upon its being inflated by social prestige; it is a social privilege.

The whole economic system of Capitalism is an offshoot of a devouring and overwhelming lust, of a kind that can hold sway only in a society that has deliberately renounced the Christian asceticism and turned away from Heaven to give itself over exclusively to earthly gratifications. ... It is the result of a secularization of economic life, and by it the hierarchical subordination of the material to the spiritual is inverted. The autonomy of economics has ended in their dominating the whole life of human societies: the worship of Mammon has become the determining force of the age. And the worst of it is that this undisguised "mammonism" is regarded as a very good thing, an attainment to the knowledge of truth and a release from illusions. Economic materialism formulates this to perfection when it brands the whole spiritual life of man as a deception and a dream.

The problem is not to discover in oneself the truth of one's sex, but, rather, to use one's sexuality henceforth to arrive at a multiplicity of relationships. And, no doubt, homosexuality is not a form of desire but something desirable. Therefore, we have to work at becoming homosexuals.

Wonder is the feeling of a philosopher, and philosophy begins in wonder.

We are far more liable to catch the vices than the virtues of our associates.

Muhammad brought down from heaven and put into the Koran not religious doctrines only, but political maxims, criminal and civil laws, and scientific theories. The Gospels, on the other hand, deal only with the general relations between man and God and between man and man. Beyond that, they teach nothing and do not oblige people to believe anything. That alone, among a thousand reasons, is enough to show that Islam will not be able to hold its power long in ages of enlightenment and democracy, while Christianity is destined to reign in such ages, as in all others.

I wish to propose for the reader's favourable consideration a doctrine which may, I fear, appear wildly paradoxical and subversive. The doctrine in question is this: that it is undesirable to believe a proposition when there is no ground whatever for supposing it true.

100 per cent of us die, and the percentage cannot be increased.

Truth is great and its effectiveness endures. 

No matter how honest scientists think they are, they are still influenced by various unconscious assumptions that prevent them from attaining true objectivity. Expressed in a sentence, Fort's principle goes something like this: People with a psychological need to believe in marvels are no more prejudiced and gullible than people with a psychological need not to believe in marvels.

The very cannibalism of the counterrevolution will convince the nations that there is only one way in which the murderous death agonies of the old society and the bloody birth throes of the new society can be shortened, simplified and concentrated, and that way is revolutionary terror.

He was as great as a man can be without morality.

When I play with my cat, who knows whether I do not make her more sport than she makes me?

I must confess that my estimate of Lovecraft would not have pleased his most ardent admirers. The view I expressed in that book was that, while Lovecraft was distinctly a creative genius in his own way, his pessimism should not be taken too seriously; that it was the pessimism of a sick recluse, and had about it an element of rassentiment, a kind of desire to take revenge on the world that rejected him. In short, Lovecraft was a 19th century romantic, born in the wrong time. Most men of genius dislike their own age, but the really great ones impose their own vision on the age. The weak ones turn away into a world of gloomy fantasy.

Philosophy hasn't made any progress?-If someone scratches where it itches, do we have to see progress? Is it not genuine scratching otherwise, or genuine itching?

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?

Better to be despised for too anxious apprehensions, than ruined by too confident a security.

Buddhism is the most colossal example in the history of applied metaphysics.

The steady drip of water causes stone to hollow and yield.

The world is upheld by the veracity of good men: they make the earth wholesome.

Am I a free agent, or am I merely the manifestation of a foreign power? Neither appear sufficiently well founded.By the most courageous resolve of my life am I reduced to this! what Power can save me from it, from myself?

Fear is the antidote to boredom: the remedy must be stronger than the disease.

We're more connected than ever but lonelier. Not because of smartphones - because of capitalism. Atomized individuals competing for scarce resources can't build community. Work exhaustion leaves no energy for relationships. Geographic mobility destroys local bonds. Loneliness is economic structure, not personal failure.

I can assure you that no kingdom has ever had as many civil wars as the kingdom of Christ.

Being asked what learning is the most necessary, he replied, "How to get rid of having anything to unlearn.

The Protestant churches generally hold that the elements of the sacrament are flesh and blood only in a tropical sense; they nourish our souls as meat and the juice of it would our bodies. But the Catholics maintain that they are literally just that; although they possess all the sensible qualities of wafer-cakes and diluted wine. But we can have no conception of wine except what may enter into a belief, either -

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.

Often things realised in thought are more vivid than than the same things in inattentive physical experience. But the things apprehended as mental are always subject to the condition that we come to a stop when we come to explore ever higher grades of complexity in their realised relationships. We always find tat we have thought of just this - whatever it may be - and of no more.

Kierkegaard writes: If Christianity were so easy and cozy, why should God in his Scriptures have set Heaven and Earth in motion and threatened eternal punishments? - Question: But then in that case why is this Scriptures so unclear?

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.

Our minds are finite, and yet even in these circumstances of finitude we are surrounded by possibilities that are infinite, and the purpose of human life is to grasp as much as we can out of the infinitude.

Since the only things we remember are humiliations and defeats, what is the use of all the rest?

Do not repeat slander; you should not hear it, for it is the result of hot temper.

Late at night. I feel like falling into a frenzy, doing some unprecedented thing to release myself, but I don't see against whom, against what...

For joys fall not to the rich alone, nor has he lived ill, who from birth to death has passed unknown.
