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.
