Thus, under these assumptions, namely, if the value of commodities were constant and appeared so, if the component value of the commodity-product which resolves itself into revenues were to remain a constant magnitude and always appeared as such, and finally, if this given and constant component value always split into constant proportions of wages, profit and rent — even under these assumptions, the real movement would necessarily appear in distorted form; not as the splitting of a previously given magnitude of value into three parts which assume mutually independent forms of revenue, but, on the contrary, as the formation of this magnitude of value from the sum of the independent and separately determined, each by itself, constituent elements — wages, profit and ground-rent. This illusion would necessarily arise, because in the actual movement of individual capitals, and the commodities produced by them, not the value of commodities would appear to be a precondition of its splitting but, conversely, the components into which it is split function as a precondition of the value of the commodities. In the first place, we have seen that to every capitalist the cost-price of his commodities appears as a given magnitude and continually appears as such in the actual price of production. The cost-price, however, is equal to the value of the constant capital, the advanced means of production, plus the value of labour-power, which, however, appears to the agent of production in the irrational form of the price of labour, so that wages simultaneously appear as revenue of the labourer. The average price of labour is a given magnitude, because the value of labour-power, like that of any other commodity, is determined by the necessary labour-time required for its reproduction. But as concerns that portion of the value of commodities which is embodied in wages, it does not arise from the fact that it assumes this form of wages, that the capitalist advances to the labourer his share of his own product in the form of wages, but from the fact that the labourer produces an equivalent for his wages, i.e., that a portion of his daily or annual labour produces the value contained in the price of his labour-power. But wages are stipulated by contract, before their corresponding value equivalent has been produced. As an element of price, whose magnitude is given before the commodity and its value have been produced, as a constituent part of the cost-price, wages thereby do not appear as a portion which detaches itself in independent form from the total value of the commodity, but rather, conversely, as a given magnitude, which predetermines this value, i.e., as a creator of price and value. A role similar to that of wages in the cost-price of commodities is played by the average profit in their price of production, for the price of production is equal to cost-price plus average profit on the advanced capital. This average profit figures practically, in the mind and calculation of the capitalist himself, as a regulating element, not merely in so far as it determines the transfer of capitals from one sphere of investment into another, but also in all sales and contracts which embrace a process of reproduction extending over long periods. But so far as it figures in this manner, it is a pre-existent magnitude, which is in fact independent of the value and surplus-value produced in any particular sphere of production, and thus even more so in the case of any individual investment of capital in any sphere of production. Rather than appearing as a result of a splitting of value, it manifests itself much more as a magnitude independent of the value of the produced commodities, as pre-existing in the process of production of commodities and itself determining the average price of the commodities, i.e., as a creator of value. Indeed, the surplus-value, owing to the separation of its various portions into mutually, completely unrelated forms, appears in still more concrete form as a prerequisite for creating commodity-value. A part of the average profit in the form of interest confronts the functioning capitalist independently as an assumed element in the production of commodities and of their value. No matter how much the magnitude of the interest fluctuates, at each moment and for every capitalist it is a given magnitude entering into the cost-price of the commodities produced by him as individual capitalist. The same role is played by ground-rent in the form of lease money fixed by contract for the agricultural capitalist, and in the form of rent for business premises in the case of other entrepreneurs. These portions into which surplus-value is split, being given as elements of cost-price for the individual capitalist, appear conversely therefore as creators of surplus-value; creators of a portion of the price of commodities, just as wages create the other. The secret wherefore these products of the splitting of commodity-value constantly appear as prerequisites for the formation of value itself is simply this, that the capitalist mode of production, like any other, does not merely constantly reproduce the material product, but also the social and economic relations, the characteristic economic forms of its creation. Its result, therefore, appears just as constantly presupposed by it, as its presuppositions appear as its results. And it is this continual reproduction of the same relations which the individual capitalist anticipates as self-evident, as an indubitable fact. So long as the capitalist mode of production persists as such, a portion of the newly added labour continually resolves itself into wages, another into profit (interest and profit of enterprise), and a third into rent. In contracts between the owners of various agencies of production this is always assumed, and this assumption is correct, however much the relative proportions may fluctuate in individual cases. The definite form in which the parts of value confront each other is presupposed because it is continually reproduced, and it is continually reproduced because it is continually presupposed.
