CHAPTER I.

COMMODITIES.

Table of Contents

At first sight the wealth of society under the capitalist system presents itself as an immense accumulation of commodities, its unit being a single commodity. But every commodity has a twofold aspect, that of use value and exchange value.2

A commodity is first of all, in the language of English economists, any thing necessary, useful or pleasant in life, an object of human wants, a means of existence in the broadest sense of the word. This property of commodities to serve as use-values coincides with their natural palpable existence. Wheat e. g. is a distinct use-value differing from the use-values cotton, glass, paper, etc. Use-value has a value only in use and is realized only in the process of consumption. The same use-value may be utilized in various ways. But the extent of its possible applications is circumscribed by its distinct properties. Furthermore, it is thus limited not only qualitatively but also quantitatively. According to their natural properties the various use-values have different measures, such as a bushel of wheat, a quire of paper, a yard of linen, etc.

Whatever the social form of wealth may be, use-values always have a substance of their own, independent of that form. One can not tell by the taste of wheat whether it has been raised by a Russian serf, a French peasant, or an English capitalist. Although the object of social wants and, therefore, mutually connected in society, use-values do not bear any marks of the relations of social production. Suppose, we have a commodity whose use-value is that of a diamond. We can not tell by looking at the diamond that it is a commodity. When it serves as a use-value, aesthetic or mechanical, on the breast of a harlot, or in the hand of a glasscutter, it is a diamond and not a commodity. It is the necessary pre-requisite of a commodity to be a use-value, but it is immaterial to the use-value whether it is a commodity or not. Use-value in this indifference to the nature of its economic destination, i.e. use-value as such lies outside the sphere of investigation of political economy.3 It falls within the sphere of the latter only in so far as it forms its own economic destination. It forms the material basis which directly underlies a definite economic relation called exchange value.

Exchange-value appears at first sight as a quantitative relation, as a proportion in which use-values are exchanged for one another. In such a relation they constitute equal exchangeable quantities. Thus, a volume of Propercius and eight ounces of snuff may represent the same exchange value, in spite of the dissimilar use-values of tobacco and elegy. As exchange-value, one kind of use-value is worth as much as another kind, if only taken in right proportion. The exchange value of a palace can be expressed in a certain number of boxes of shoe-blacking. On the contrary, London manufacturers of shoe-blacking have expressed the exchange value of their many boxes of blacking, in palaces. Thus, entirely apart from their natural forms and without regard to the specific kind of wants for which they serve as use-values, commodities in certain quantities equal each other, take each other’s place in exchange, pass as equivalents, and in spite of their variegated appearance, represent the same entity.

Use-values are primarily means of existence. These means of existence, however, are themselves products of social life, the result of expended human vital power, materialized labor. As the embodiment of social labor, all commodities are the crystallization of the same substance. Let us now consider the nature of this substance, i.e., of labor, which is expressed in exchange value.

Let one ounce of gold, one ton of iron, one quarter of wheat and twenty yards of silk represent equal exchange values. As equivalents, in which the qualitative difference between their use-values has been eliminated, they represent equal volumes of the same kind of labor. The labor which is equally embodied in all of them must be uniform, homogeneous, simple labor. It matters as little in the case of labor whether it be embodied in gold, iron, wheat, or silk, as it does in the case of oxygen, whether it appears in the rust of iron, in the atmosphere, in the juice of a grape, or in the blood of a human being. But the digging of gold, the extraction of iron from a mine, the raising of wheat and the weaving of silk are so many kinds of labor, differing in quality. As a matter of fact, what in reality appears as a difference in use-values, is in the process of production, a difference in the work creating those use-values. Just as labor, which creates exchange value, is indifferent to the material of use-values, so it is to the special form of labor itself. Furthermore, the different use-values are the products of the work of different individuals, consequently the result of various kinds of labor differing individually from one another. But as exchange values, they represent the same homogeneous labor, i.e., labor from which the individuality of the workers is eliminated. Labor creating exchange value is, therefore, abstract general labor.

If one ounce of gold, one ton of iron, one quarter of wheat, and twenty yards of silk are exchange values of equal magnitude or equivalents; then one ounce of gold, half a ton of iron, three bushels of wheat and five yards of silk are exchange values of different magnitudes, and this quantitative difference is the only difference of which they are capable as exchange values. As exchange values of different magnitudes, they represent greater or smaller quantities of that simple, homogeneous, abstract, general labor, which forms the substance of exchange value. The question arises, how are these quantities to be measured? Or, rather what constitutes the substance of labor, which makes it capable of quantitative measurement, since the quantitative differences of commodities in their capacity of exchange values are but quantitative differences of labor embodied in them. Just as motion is measured by time, so is labor measured by labor-time. Given the quality of labor, the difference in its duration is the only property by which it can be distinguished. As labor-time, labor has the same standard of measurement as the natural time measures, viz., hours, days, weeks, etc. Labor-time is the vital substance of labor, independent of its form, composition, individuality; it is its vital substance quantitatively, having at the same time its own inherent measure. Labor-time embodied in the use-values of commodities is the substance which makes exchange values and, therefore, commodities of them and at the same time serves to measure definite quantities of their value. Corresponding quantities of different use-values, in which the same quantity of labor-time is embodied, are equivalents; or, to put it in another form, all use-values are equivalents when taken in proportions containing the same quantity of expended, materialized labor-time. As exchange values, all commodities are but definite measures of congealed labor-time.

To understand how exchange value is determined by labor-time, the following main points must be kept in mind: The reduction of labor to simple labor, devoid of any quality, so to speak; the specific ways and means by which exchange—value-creating, i.e., commodity producing labor becomes social labor; finally, the difference between labor as the producer of use-values, and labor as the creator of exchange values.

In order to measure commodities by the labor-time contained in them, the different kinds of labor must be reduced to uniform, homogeneous, simple labor, in short, to labor which is qualitatively the same, and, therefore, differs only in quantity.

This reduction appears to be an abstraction; but it is an abstraction which takes place daily in the social process of production. The conversion of all commodities into labor-time is no greater abstraction nor a less real process than the chemical reduction of all organic bodies to air. Labor, thus measured by time, does not appear in reality as the labor of different individuals. but on the contrary, the various working individuals rather appear as mere organs of labor; or, in so far as labor is represented by exchange values, it may be defined as human labor in general. This abstraction of human labor in general virtually exists in the average labor which the average individual of a given society can perform—a certain productive expenditure of human muscles, nerves, brain, etc. It is unskilled labor to which the average individual can be put and which he has to perform in one way or another. The character of this average labor varies in different countries and at different stages of civilization, but appears fixed in a particular society. Unskilled labor constitutes the bulk of all labor performed in capitalist society, as may be seen from all statistics.

It is obvious that if A spends six hours in the production of iron and six hours on linen, and B also produces iron during six hours and linen during another six hours, it is but a different application of the same labor time that would be expended, if A produced iron during twelve hours, while B worked twelve hours on linen. But how about skilled labor which rises above the level of average labor by its higher intensity, by its greater specific gravity? This kind of labor resolves itself into unskilled labor composing it; it is simple labor of a higher intensity, so that one day of skilled labor, e. g., may equal three days of unskilled labor. This is not the place to consider the laws regulating this reduction. It is clear, however, that such reduction does take place, for, as exchange value, the product of the most skilled labor is, when taken in a certain proportion, equivalent to the product of unskilled average labor, or equal to a definite quantity of that unskilled labor.

The determination of exchange-value by means of labor-time implies, further, the fact that an equal quantity of labor is embodied in any given commodity, e. g., a ton of iron, no matter whether it is the work of A or B, that is to say, various individuals expend an equal amount of labor-time for the production of the same use-value of a given quality and quantity. It is thus assumed that the labor-time contained in a commodity is the labor-time necessary for its production, i.e., it is the labor-time which is required for the production of another specimen of the same commodity under the same general conditions of production.

The conditions of labor, which creates exchange value, as shown by the analysis of the latter, are social conditions of labor or conditions of social labor. Social, not in the ordinary, but in a special sense. It is a specific form of the social process. The homogeneous simplicity of labor means first of all equality of the labors of various individuals, a reciprocal relation of equality of their labors determined by the actual reduction of all kinds of labor to uniform labor. The labor of every individual, as far as it is expressed in exchange value possesses this social character of equality and finds expression in exchange value only in so far as it is a relation of equality with the labor of all other individuals.

Furthermore, the labor-time of a single individual is directly expressed in exchange value as universal labor-time, and this universal character of individual labor is the manifestation of its social character. The labor-time represented by exchange value is the labor-time of an individual, but of an individual undistinguished from other individuals in so far as they perform the same labor; therefore, the time required by one individual for the production of a certain commodity is the necessary labor-time which any other individual would have to spend on the production of the same commodity. It is the labor-time of an individual, his labor-time, but only as labor-time common to all, regardless as to which particular individual’s labor-time it is. As universal labor-time it is represented in a universal product, in a universal equivalent, in a definite quantity of materialized labor-time: the latter is indifferent as to the particular form of use-value in which it appears directly as the product of an individual, and may be turned at will into any other form of use-value to represent the product of any other individual. Only as such a universal quantity, is it a social quantity. In order to result in exchange value, the labor of an individual must be turned into a universal equivalent, i.e., the labor-time of an individual must be expressed as universal labor-time, or universal labor-time as that of an individual. It is the same as though different individuals had put together their labor-time and contributed the different quantities of labor-time at their common disposal in the form of different use-values. The labor-time of the individual is thus, in fact, the labor time which society requires for the production of a certain use-value, i.e., for the satisfaction of a certain want. But the question that interests us here is as to the specific form in which labor acquires a social character. Let us suppose that a certain quantity of labor-time of a spinner is realized in 100 lbs. of yarn. Suppose 100 yards of linen, the product of the weaver, represent the same quantity of labor-time. Inasmuch as these two products represent equal quantities of universal labor-time and, hence, are equivalents of every use-value which contains the same amount of labor-time, they are also equivalent to each other. Only because the labor-time of the spinner and that of the weaver take the form of universal labor-time and their products appear as universal equivalents, is the labor of the weaver realized for the spinner, and that of the spinner, for the weaver, the labor of one takes the place of the labor of the other, i.e., the social character of their labors is realized for both. Quite different it was under the patriarchal system of production, when spinner and weaver lived under the same roof, when the female members of the family did the spinning, and the male members did the weaving to supply the wants of their own family; then yarn and linen were social products, spinning and weaving were social labor within the limits of the family. But their social character did not manifest itself in the fact that yarn, as a universal equivalent, could be exchanged for linen as a universal equivalent, or that one was exchanged for another, as identical and equivalent expressions of the same universal labor-time. It was rather the family organization with its natural division of labor that impressed its peculiar social stamp on the product of labor. Or, let us take the services and payments in kind of the Middle Ages. It was the specific kind of labor performed by each individual in its natural form, the particular and not the universal aspect of labor, that constituted then the social tie. Or, let us finally take labor carried on in common in its primitive natural form, as we find it at the dawn of history of all civilized races.4 It is clear that in this case labor does not acquire its social character from the fact that the labor of the individual takes on the abstract form of universal labor or that his product assumes the form of a universal equivalent. The very nature of production under a communal system makes it impossible for the labor of the individual to be private labor and his product to be a private product; on the contrary, it makes individual labor appear as the direct function of a member of a social organism. On the contrary, labor, which is expressed in exchange value, at once appears as the labor of a separate individual. It becomes social labor only by taking on the form of its direct opposite, the form of abstract universal labor.

Labor, which creates exchange value, is, finally, characterized by the fact that even the social relations of men appear in the reversed form of a social relation of things. Only in so far as two use-values are in a mutual relation of exchange values does the labor of different persons possess the common property of being identical universal labor. Hence, if it be correct to say that exchange value is a relation between persons,5 it must be added that it is a relation disguised under a material cover. Just as a pound of iron and a pound of gold represent the same weight in spite of their different physical and chemical properties, so do two use-values, as commodities containing the same quantity of labor-time, represent the same exchange value. Exchange value thus appears as the natural social destination of use-values, a property which they possess by virtue of being things and in consequence of which they are exchanged for one another in definite proportions, or form equivalents, just as chemical elements combine in certain proportions, forming chemical equivalents. It is only through the habit of everyday life that we come to think it perfectly plain and commonplace, that a social relation of production should take on the form of a thing, so that the relation of persons in their work appears in the form of a mutual relation between things, and between things and persons.

In commodities this mystification is as yet very simple. It is more or less plain to everybody that a relation of commodities as exchange values is nothing but a mutual relation between persons in their productive activity. This semblance of simplicity disappears in higher productive relations. All the illusions in regard to the monetary system are due to the fact that money is not regarded as something representing a social relation of production, but as a product of nature endowed with certain properties. The modern economists who sneer at the illusions of the monetary system, betray the same illusion as soon as they have to deal with higher economic forms, as, e. g., capital.6 It breaks forth in their confession of naive surprise, when what they have just thought to have defined with great difficulty as a thing suddenly appears as a social relation and then reappears to tease them again as a thing, before they have barely managed to define it as a social relation.

Since the exchange value of commodities is, in fact, nothing but a mutual relation of the labors of individuals—labors which are similar and universal—nothing but a material expression of a specific social form of labor, it is a tautology to say that labor is the only source of exchange value and consequently of wealth, in so far as the latter consists of exchange values. Similarly, it is a tautology to say that matter in its natural state has no exchange value, because it does not contain any labor, and that exchange value as such does not contain matter. But when William Petty calls labor the father and earth the mother of wealth, or when Bishop Berkeley asks whether the four elements and man’s labour therein, be not the true source of wealth,7 or when the American, Thomas Cooper puts it popularly: Take away from a piece of bread the labour bestowed by the baker on the flour, by the miller on the grain brought to him, by the farmer in ploughing, sowing, tending, gathering, threshing, cleaning and transporting the seed, and what will remain? A few grains of grass, growing wild in the woods, and unfit for any human purpose8—then all these views do not refer to abstract labor as the source of exchange value, but to concrete labor as the source of material wealth; in short, to labor in so far as it produces use-values. In assuming that a commodity has use-value we assume the special usefulness and distinct fitness of the labor absorbed by it, but that is all there is to the view of labor as useful labor from the standpoint of commodity. Considering bread as a use-value, we are interested in its properties as an article of food and not at all in the different kinds of labor of the farmer, miller, baker, etc. If by some invention nineteen-twentieths of this labor could be saved, the loaf of bread would still render the same service as before. If it fell ready-made from the sky it would not lose a single atom of its use-value. While labor which creates exchange value is realized in the equality of commodities as universal equivalents, labor as a productive activity with a useful purpose is realized in the endless variety of use-values created by it. While labor which creates exchange values is abstract, universal and homogeneous, labor which produces use-values is concrete and special and is made up of an endless variety of kinds of labor according to the way in which and the material to which it is applied.

It is wrong to speak of labor in so far as it is applied to the production of use-values as of the only source of wealth, namely, the material wealth produced by it. Being an activity intended to adapt materials to this or that purpose, it requires matter as a pre-requisite. In different use-values the proportion between labor and raw material varies greatly, but use-value always has a natural substratum. Labor, as an activity, directed to the adaptation of raw material in one form or another, is a natural condition of human existence, a condition of exchange of matter between man and nature, independent of all social forms. On the contrary, labor producing exchange value is a specifically social form of labor. Tailoring, e. g., in its material manifestation as a distinct productive activity, produces a coat, but not the exchange value of the coat. The latter is produced not by the labor of the tailor as such, but by abstract universal labor, and that belongs to a certain organization of society which has not been brought about by the tailor. Thus, the women under the ancient system of house industry made coats without producing the exchange value of the coats. Labor as a source of material wealth was known to Moses, the legislator, as well as to Adam Smith, the customs official.9

Let us consider now some propositions which follow from the determination of exchange value by labor-time.

As a use-value, every commodity owes its usefulness to itself. Wheat, e. g., serves as an article of food. A machine saves labor to a certain extent. This function of a commodity by virtue of which it serves only as use-value, as an article of consumption, may be called its service, the service which it renders as use-value. But as an exchange value, a commodity is always regarded as a result; the question in this case is not as to the service which it renders, but as to the service10 which it has been rendered in its production. Thus, the exchange value of a machine is determined not by the quantity of labor-time which it saves, but by the quantity of labor-time which has been expended on its own production and which is, therefore, required to produce a new machine of the same kind.

If, therefore, the quantity of labor-time required for the production of commodities remained constant, their exchange value would remain the same. But the ease and the difficulty of production are constantly changing. If the productivity of labor increases, the same use-value will be produced in less time. If the productivity of labor declines, more time will be required for the production of the same use-value. Thus, the labor-time contained in a commodity or its exchange-value is a variable quantity, increasing or diminishing in an inverse ratio to the rise and fall of the productivity of labor. The productive power of labor which is applied in the manufacturing industry on a predetermined scale depends in the agricultural and extractive industries also on natural conditions which are beyond human control. The same labor will yield a
