CHAPTER I.

COMMODITIES.

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.

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 prerequisite 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. 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.
