Surplus value. Production time. Circulation time. Turnover time
Change of form and of matter in the circulation of capital.-- C-M-C. M-C-M.
A change of form [Formwechsel] and a change of matter [Stoffwechsel] take place simultaneously in the circulation of capital. We must begin here not with the presupposition of M, but with the production process. In production, as regards the material side, the instrument is used up and the raw material is worked up. The result is the product -- a newly created use value, different from its elemental presuppositions. As regards the material side, a product is created only in the production process. This is the first and essential material change. On the market, in the exchange for money, the product is expelled from the circulation of capital and falls prey to consumption, becomes object of consumption, whether for the final satisfaction of an individual need or as raw material for another capital. In the exchange of the commodity for money, the material and the formal changes coincide; for, in money, precisely the content itself is part of the economic form. The retransformation of money into commodity is here, however, at the same time present in the retransformation of capital into the material conditions of production. The reproduction of a specific use value takes place, just as well as of value as such. But, just as the material element here was posited, from the outset, at its entry into circulation, as a product, so the commodity in turn was posited as a condition of production at the end of it. To the extent that money figures here as medium of circulation, it does so indeed only as mediation of production, on one side with consumption, in the exchange where capital discharges value in the form of the product, and as mediation, on the other side, between production and production, where capital discharges itself in the form of money and draws the commodity in the form of the condition of production into its circulation. Regarded from the material side of capital, money appears merely as a medium of circulation; from the formal side, as the nominal measure of its realization, and, for a specific phase, as value-for-itself; capital is therefore C-M-M-C just as much as it is M-C- C-M, and this in such a way, specifically, that both forms of simple circulation here continue to be determinants, since M-M is money, which creates money, and C-C a commodity whose use value is both reproduced and increased. In regard to money circulation, which appears here as being absorbed into and determined by the circulation of capital, we want only to remark in passing -- for the matter can be thoroughly treated only after the many capitals have been examined in their action and reaction upon one another -- that money is obviously posited in different aspects here.
