                                    I. The Formulation of the Question

   If we study the annual function of social capital — hence of the total capital of which the individual capitals form only fractional parts, whose movement is their individual movement and simultaneously integrating link in the movement of the total capital — and its results, i.e., if we study the commodity-product furnished by society during the year, then it must become apparent how the process of reproduction of the social capital takes place, what characteristics distinguish this process of reproduction from the process of reproduction of an individual capital, and what characteristics are common to both. The annual product includes those portions of the social product which replace capital, namely social reproduction, as well as those which go to the consumption-fund, those which are consumed by labourers and capitalists, hence both productive and individual consumption. It comprises also the reproduction (i.e., maintenance) of the capitalist class and the working-class, and thus the reproduction of the capitalist character of the entire process of production.

   It is evidently the circulation formula

                      C' — {                    M — C ... P... C'

                                                   m — c

   which we have to analyse, and consumption necessarily plays a role in it; for the point of departure, C' = C + c, the commodity-capital embraces both the constant and variable capital-value, and the surplus-value. Its movement therefore includes both individual and productive consumption. In the circuits M — C ... P... C'— M' and P ... C'— M'— C ... P, the movement of the capital is the starting and finishing point. And of course this includes consumption, for the commodity, the product, must be sold. When this has assumedly been done it is immaterial for the movement of the individual capital what becomes of the commodities subsequently. On the other hand in the movement of C' ... C' the conditions of social reproduction are discernible precisely from the fact that it must be shown what becomes of every portion of value of this total product, C'. In this case the total process of reproduction includes the process of consumption brought about by the circulation quite as much as the process of reproduction of the capital itself.

   For our present purpose this process of reproduction must be studied from the point of view of the replacement of the value as well as the substance of the individual component parts of C'. We cannot rest content any longer, as we did in the analysis of the value of the product of the individual capital, with the assumption that the individual capitalist can first convert the component parts of his capital into money by the sale of his commodities, and then reconvert them into productive capital by renewed purchase of the elements of production in the commodity-market. Inasmuch as those elements of production are by nature material, they represent as much a constituent of the social capital as the individual finished product, which is exchanged for them and replaced by them. Contrariwise the movement of that portion of the social commodity-product which is consumed by the labourer in expending his wages, and by the capitalist in expending his surplus-value, not only forms an integral part of the movement of the total product but intermingles with the movements of the individual capitals, and therefore this process cannot be explained by merely assuming it.

   The question that confronts us directly is this: How is the capital consumed in production replaced in value out of the annual product and how does the movement of this replacement intertwine with the consumption of the surplus-value by the capitalists and of the wages by the labourers? It is then first a matter of reproduction on a simple scale. It is furthermore assumed that products are exchanged at their values and also that there is no revolution in the values of the component parts of productive capital. The fact that prices diverge from values cannot, however, exert any influence on the movements of the social capital. On the whole, there is the same exchange of the same quantities of products, although the individual capitalists are involved in value-relations no longer proportional to their respective advances and to the quantities of surplus-value produced singly by every one of them. As for revolutions in value, they do not alter anything in the relations between the value-components of the total annual product, provided they are universally and evenly distributed. To the extent however that they are partially and unevenly distributed, they represent disturbances which, in the first place, can be understood as such only as far as they are regarded as divergences from unchanged value-relations, but in the second place, once there is proof of the law according to which one portion of the value of the annual product replaces constant, and another portion variable capital, a revolution either in the value of the constant or that of the variable capital would not alter anything in this law. It would change merely the relative magnitudes of the portions of value which function in the one or the other capacity, because other values would have taken the places of the original ones.

   So long as we looked upon the production of value and the value of the product of capital individually, the bodily form of the commodities produced was wholly immaterial for the analysis, whether it was machines, for instance, corn, or looking glasses. It was always but a matter of illustration, and any branch of production could have served that purpose equally well. What we dealt with was the immediate process of production itself, which presents itself at every point as the process of some individual capital. So far as the reproduction of capital was concerned, it was sufficient to assume that that portion of the product in commodities which represents capital-value finds an opportunity in the sphere of circulation to reconvert itself into its elements of production and thus into its form of productive capital; just as it sufficed to assume that both the labourer and the capitalist find in the market those commodities on which they spend their wages and the surplus-value. This merely formal manner of presentation is no longer adequate in the study of the total social capital and of the value of its products. The reconversion of one portion of the value of the product into capital and the passing of another portion into the individual consumption of the capitalist as well as the working-class form a movement within the value of the product itself in which the result of the aggregate capital finds expression; and this movement is not only a replacement of value, but also a replacement in material and is therefore as much bound up with the relative proportions of the value-components of the total social product as with their use-value, their material shape. Simple reproduction, reproduction on the same scale, appears as an abstraction, inasmuch as on the one hand the absence of all accumulation or reproduction on an extended scale is a strange assumption in capitalist conditions, and on the other hand conditions of production do not remain exactly the same in different years (and this is assumed). The assumption is that a social capital of a given magnitude produces the same quantity of commodity-value this year as last, and supplies the same quantum of wants, although the forms of the commodities may change in the process of reproduction. However, as far as accumulation does take place, simple reproduction is always a part of it, and can therefore be studied by itself, and is an actual factor of accumulation. The value of the annual product may decrease, although the quantity of use-values may remain the same; or the value may remain the same although the quantity of the use-values may decrease; or the quantity of value and of the reproduced use-values may decrease simultaneously. All this amounts to reproduction taking place either under more favourable conditions than before or under more difficult ones, which may result in imperfect — defective — reproduction. All this can refer only to the quantitative aspect of the various elements of reproduction, not to the role which they play as reproducing capital or as a reproduced revenue in the entire process.
