In 1867 there appeared in Hamburg Capital, a Critical Analysis of Capitalist Production, Volume I, [1] Marx’s chief work, which expounds the foundations of his economic socialist conceptions and the main features of his criticism of existing society, the capitalist mode of production, and its consequences.

Of the many important discoveries through which Marx has inscribed his name in the annals of science, we can here dwell on only two.

The revolution in the whole conception of world history

The whole previous view of history was based on the conception that the ultimate causes of all historical changes are to be looked for in the changing ideas of human beings, and that of all historical changes political changes are the most important and dominate the whole of history. But the question was not asked as to whence the ideas come into men’s minds and what the driving causes of the political changes are. Only upon the newer school of French, and partly also of English, historians had the conviction forced itself that, since the Middle Ages at least, the driving force in European history was the struggle of the developing bourgeoisie with the feudal aristocracy for social and political domination. Now Marx has proved that the whole of previous history is a history of class struggles, that in all the manifold and complicated political struggles the only thing at issue has been the social and political rule of social classes, the maintenance of domination by older classes and the conquest of domination by newly arising classes.

To what, however, do these classes owe their origin and their continued existence? They owe it to the particular material, physically sensible conditions in which society at a given period produces and exchanges its means of subsistence.

The feudal rule of the Middle Ages rested on the self-sufficient economy of small peasant communities, which themselves produced almost all their requirements, in which there was almost no exchange and to which the arms-bearing nobility lent protection from without and national or at least political cohesion. When the towns arose and with them a separate handicraft industry and commercial intercourse, at first internal and later international, the urban bourgeoisie developed, and already during the Middle Ages achieved, in struggle with the nobility, its inclusion in the feudal order as likewise a privileged estate.

But with the discovery of the extra-European world, from the middle of the fifteenth century onwards, this bourgeoisie acquired a far more extensive sphere of trade and therewith a new spur for its industry; in the most important branches handicrafts were supplanted by manufacture, now on a factory scale, and this again was supplanted by large-scale industry, which had become possible owing to the discoveries of the previous century, especially that of the steam-engine. Large-scale industry, in its turn, reacted on trade by driving out the old manual labour in backward countries, and creating the present-day new means of communication: steam-engines, railways, electric telegraphy, in the more developed ones.

Thus the bourgeoisie came more and more to combine social wealth and social power in its hands, while it still for a long period remained excluded from political power, which was in the hands of the nobility and the monarchy supported by the nobility. But at a certain stage — in France since the Great Revolution — it also conquered political power, and now in turn became the ruling class over the proletariat and small peasants.

From this point of view all historical phenomena are explicable in the simplest possible way — with sufficient knowledge of the particular economic condition of society, which it is true is totally lacking in our professional historians, and in the same way the conceptions and ideas of each historical period are most simply to be explained from the economic conditions of life and from the social and political relations of the period, which are in turn determined by these economic conditions.

History was for the first time placed on its real basis; the palpable but previously totally overlooked fact that men must first of all eat, drink, have shelter and clothing, and therefore must work, before they can fight for domination, pursue politics, religion, philosophy and so on — this palpable fact at last came into its historical rights.

This new conception of history, however, was of supreme significance for the socialist outlook. It showed that all previous history had moved in class antagonisms and class struggles, that there have always existed ruling and ruled, exploiting and exploited classes, and that the great majority of mankind has always been condemned to arduous labour and little enjoyment.

Why is this? Simply because in all earlier stages of development of mankind production was so little developed that the historical development could proceed only in this antagonistic form, that historical progress as a whole was assigned to the activity of a small privileged minority, while the great mass remained condemned to producing by their labour their own meagre means of subsistence and also the increasingly rich means of the privileged.

But the same investigation of history, which in this way provides a natural and reasonable explanation of the previous class rule, otherwise only explicable by the wickedness of man, also leads to the realization that, in consequence of the tremendously increased productive forces of the present time, even the last pretext has vanished for a division of mankind into rulers and ruled, exploiters and exploited, at least in the most advanced countries; that the ruling big bourgeoisie has fulfilled its historic mission, that it is no longer capable of the leadership of society and has even become a hindrance to the development of production, as the trade crises, and especially the last great collapse, and the depressed condition of industry in all countries have proved; [2] that historical leadership has passed to the proletariat, a class which, owing to its whole position in society, can only free itself by abolishing altogether all class rule, all servitude and all exploitation.

The social productive forces, which have outgrown the control of the bourgeoisie, are only waiting for the associated proletariat to take possession of them in order to bring about a state of things in which every member of society will be enabled to participate not only in production but also in the distribution and administration of social wealth, and which so increases the social productive forces and their yield by planned operation of the whole of production that the satisfaction of all reasonable needs will be assured to everyone in an ever-increasing measure. [3]


The final elucidation of the relation between capital and labour

In other words, Marx demonstrated how, within present society and under the existing capitalist mode of production, the exploitation of the worker by the capitalist takes place. Ever since political economy put forward the proposition that labour is the source of all wealth and of all value, the question has become inevitable: how is this, then, to be reconciled with the fact that the wage-worker does not receive the whole sum of value created by his labour but has to surrender a part of it to the capitalist? Both the bourgeois economists and the socialists exerted themselves to give a scientifically valid answer to this question, but in vain, until at last Marx came forward with the solution.

This solution is as follows:

The present day capitalist mode of production presupposes the existence of two social classes — on the one hand, that of the capitalists, who are in possession of the means of production and subsistence, and, on the other hand, that of the proletarians, who, being excluded from this possession, have only a single commodity for sale, their labour power, and who therefore have to sell this labour power of theirs in order to obtain possession of means of subsistence. [4] The value of a commodity is, however, determined by the socially necessary quantity of labour embodied in its production, and, therefore, also in its reproduction; the value of the labour power of an average human being during a day, month or year is determined, therefore, by the quantity of labour embodied in the quantity of means of subsistence necessary for the maintenance of this labour power during a day, month or year.

Let us assume that the means of subsistence of a worker for one day require six hours of labour for their production, or, what is the same thing, that the labour contained in them represents a quantity of labour of six hours; then the value of labour power for one day will be expressed in a sum of money which also embodies six hours of labour.

Let us assume further that the capitalist who employs our worker pays him this sum in return, pays him, therefore, the full value of his labour power.

If now the worker works six hours of the day for the capitalist, he has completely replaced the latter’s outlay — six hours’ labour for six hours’ labour.

But then there would be nothing in it for the capitalist, and the latter therefore looks at the matter quite differently. He says: I have bought the labour power of this worker not for six hours but for a whole day, and accordingly he makes the worker work 8, 10, 12, 14 or more hours, according to circumstances, so that the product of the seventh, eighth and following hours is a product of unpaid labour and wanders, to begin with, into the pocket of the capitalist.

Thus the worker in the service of the capitalist not only reproduces the value of his labour power, for which he receives pay, but over and above that he also produces a surplus value which, appropriated in the first place by the capitalist, is in its further course divided according to definite economic laws among the whole capitalist class and forms the basic stock from which arise ground rent, profit, interest — in short, all the wealth consumed or accumulated by the non-labouring classes. [5]

This, however, proved that the acquisition of riches by the present-day capitalists consists just as much in the appropriation of the unpaid labour of others as that of the slave-owner or the feudal lord exploiting serf labour, and that all these forms of exploitation are only to be distinguished by the difference in manner and method by which the unpaid labour is appropriated.

This, however, also removed the last justification for all the hypocritical phrases of the possessing classes to the effect that in the present social order right and justice, equality of rights and duties and a general harmony of interests prevail, and exposed present-day bourgeois society, no less than its predecessors, as a grandiose institution for the exploitation of the huge majority of the people by a small, ever-diminishing minority.


Modern, scientific socialism is based on these two important facts.
