All freed, fast-frozen relations, with their train of ancient and venerable prejudices and opinions, are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.
The unity of the bourgeoisie can be shaken only by the unity of the proletariat.
Mankind always sets itself only such tasks as it can solve; since, looking at the matter more closely, we will always find that the task itself arises only when the material conditions necessary for its solution already exist or are at least in the process of formation.
Since labour is motion, time is its natural measure.
Society is undergoing a silent revolution, which must be submitted to, and which takes no more notice of the human existences it breaks down than an earthquake regards the houses it subverts. The classes and the races, too weak to master the new conditions of life, must give way.
You will have to go through 15, 20, 50 years of civil wars and national struggles not only to bring about a change in society but also to change yourselves, and prepare yourselves for the exercise of political power.
In bourgeois society capital is independent and has individuality, while the living person is dependent and has no individuality.
Crack-brained meddling by the authorities [can] aggravate an existing crisis.
Titles of property, for instance railway shares, may change hands every day, and their owner may make a profit by their sale even in foreign countries, so that titles to property are exportable, although the railway itself is not.
Revolutions are the locomotives of history.
Science and democracy are the right and left hands of what I'll refer to as the move from the realm of necessity to the realm of freedom.
There is no royal road to science, and only those who do not dread the fatiguing climb of its steep paths have a chance of gaining its luminous summits. (Preface to the French edition).
The ideas of the ruling class are in every epoch the ruling ideas, i.e., the class which is the ruling material force of society, is at the same time its ruling intellectual force.
It is not the consciousness of men that determines their being, but, on the contrary, their social being that determines their consciousness.
The individual produces an object and, by consuming it, returns to himself, but returns as a productive and self reproducing individual. Consumption thus appears as a moment of production.
Society does not consist of individuals but expresses the sum of interrelations, the relations within which these individuals stand.
One capitalist always kills many.
If one wants to be an ox one can easily turn one's back on hum suffering and look after one's own skin.
The product of mental labor - science - always stands far below its value, because the labor-time necessary to reproduce it has no relation at all to the labor-time required for its original production.
Capitalist agricultural production prevents the return to the soil of its elements consumed by man in the form of food and clothing; it therefore violates the conditions necessary to lasting fertility of the soil. By this action it destroys at the same time the health of the town labourer and the intellectual life of the rural labourer.
The capitalist cannot store labour-power in warehouses after he has bought it, as he may do with the raw material.
It is absolutely impossible to transcend the laws of nature. What can change in historically different circumstances is only the form in which these laws expose themselves.
Even an entire society, a nation, or all simultaneously existing societies taken together, are not owners of the earth. They are simply its possessors, its beneficiaries, and have to bequeath it in an improved state to succeeding generations.
The monopoly of capital becomes a fetter upon the mode of production, which has sprung up and flourished along with, and under it. Centralisation of the means of production and socialisation of labour at last reach a point where they become incompatible with there capitalist integument. This integument is burst asunder. The knell of capitalist private property sounds. The expropriators are expropriated.
Anyone wanting a new house picks one from among those built on speculation or still in process of construction. The builder no longer works for his customers but for the market.
Ideas do not exist separately from language.
Be aware that the reward for labour, and quantity of labour, are quite disparate things.
The economic concept of value does not occur in antiquity .
If the labourer consumes his disposable time for himself, he robs the capitalist.
Darwin has interested us in the history of nature's technology.
There is something in human history like retribution; and it is a rule of historical retribution that its instrument be forged not by the offended, but by the offender himself. The first blow dealt to the French monarchy proceeded from the nobility, not from the peasants. The Indian revolt does not commence with the ryots, tortured, dishonoured and stripped naked by the British, but with the sepoys, clad, fed and petted, fatted and pampered by them.
Each piece of money is a mere coin, or means of circulation, only so long as it actually circulates.
Work is external to the worker. . . . It is not part of his nature; consequently he does not fulfill himself in his work but denies himself. . . . The worker therefore feels himself at home only during his leisure time, whereas at work he feels homeless.
In my free time I do differential and integral calculus.
When the sufferers learn to think, then the thinkers will learn to suffer.
If money is the bond binding me to human life, binding society to me, binding me and nature and man, is not money the bond of all bonds? Can it not dissolve and bind all ties? Is it not, therefore, the universal agent of separation?
All history is nothing but a continuous transformation of human nature.
The English have all the material requisites for the revolution. What they lack is the spirit of generalization and revolutionary ardour.
While the miser is merely a capitalist gone mad, the capitalist is a rational miser.
In order to arouse sympathy, the aristocracy was obliged to lose sight, apparently, of its own interests, and to formulate its indictment against the bourgeoisie in the interest of the exploited working class alone. Thus, the aristocracy took their revenge by singing lampoons on their new masters and whispering in his ears sinister prophesies of coming catastrophe.
Luxury is the opposite of the naturally necessary.
Natural science will in time incorporate into itself the science of man, just as the science of man will incorporate into itself natural science: there will be one science.
I am nothing but I must be everything.
Under the ideal measure of values there lurks the hard cash.
Art is always and everywhere the secret confession, and at the same time the immortal movement of its time.
Change the economic base and you will change human beings.
Hence money may be dirt, although dirt is not money.
Each pursues his private interest and only his private interest; and thereby serves the private interests of all, the general interest, without willing it or knowing it. The real point is not that each individual's pursuit of his private interest promotes the totality of private interests, the general interest. One could just as well deduce from this abstract phrase that each individual reciprocally blocks the assertion of the others' interests, so that, instead of a general affirmation, this war of all against all produces a general negation.
Necessity is blind until it becomes conscious. Freedom is the consciousness of necessity.
Beauty is the main positive form of the aesthetic assimilation of reality, in which aesthetic ideal finds it direct expression.
So in Jewry we recognise a contemporary universal anti-social phenomenon, which has reached its present pitch through a process of, historical development in which the Jews have zealously co-operated. And this evil anti-social aspect of Jewry has grown to a stage at which: it must necessarily collapse.
It might otherwise appear paradoxical that money can be replaced by worthless paper; but that the slightest alloying of its metallic content depreciates it.
It is a bad thing to perform menial duties even for the sake of freedom; to fight with pinpricks, instead of with clubs. I have become tired of hypocrisy, stupidity, gross arbitrariness, and of our bowing and scraping, dodging, and hair-splitting over words. Consequently, the government has given me back my freedom.
A man cannot become a child again, or he becomes childish.
Nothing can have value without being an object of utility.
Nature is man's inorganic body -- that is to say, nature insofar as it is not the human body. Man lives from nature -- i.e., nature is his body -- and he must maintain a continuing dialogue with it is he is not to die. To say that man's physical and mental life is linked to nature simply means that nature is linked to itself, for man is a part of nature.
To be radical is to grasp things by the root.
Money does not arise by convention, any more than the state does. It arises out of exchange, and arises naturally out of exchange; it is a product of the same.
...it is all the more clear what we have to accomplish at present: I am referring to ruthless criticism of all that exists, ruthless both in the sense of not being afraid of the results it arrives at and in the sense of being just as little afraid of conflict with the powers that be.
In proportion therefore, as the repulsiveness of the work increases, the wage decreases.
