A superficial glance suffices to show that capitalist reproduction as a social whole must not be regarded simply as a mechanical summation of all the separate processes of individual capitalist reproduction. We have seen, for instance, that one of the fundamental conditions for enlarged reproduction by an individual capitalist is a corresponding increase of his opportunities to sell on the commodity market. But the individual capitalist may not always expand because of an absolute increase in the absorptive capacity of the market, but also as a result of the competitive struggle, at the cost of other individual capitalists. Thus one capitalist may win what another or many others who have been shouldered from the market must write off as a loss. This process will enable one capitalist to increase his reproduction by the amount that it compels others by losses to restrict their own. One capitalist will be able to engage in enlarged reproduction because others cannot even achieve simple reproduction. In the same way, one capitalist may enlarge his reproduction by using labour power and means of production which another's bankruptcy, that is his partial or complete retirement from reproduction, has set free. These commonplaces prove that reproduction of the social capital as a whole is not the same as the reproduction of the individual capitalist raised to the _n_th degree. They show that the reproductive activities of individual capitalists ceaselessly cut across one another and to a greater or smaller degree may cancel each other out. Therefore we must clarify our concept of reproduction of capital as a whole, before we examine the laws and mechanisms of capitalist total reproduction. We must raise the question whether it is even possible to deduce anything like total reproduction from the disorderly jumble of individual capitals in constant motion, changing from moment to moment according to uncontrollable and incalculable laws, partly running a parallel course, and partly intersecting and cancelling each other out. Can one actually talk of total social capital of society as an entity, and if so, what is the real meaning of this concept? That is the first question a scientific examination of the laws of reproduction has to consider. At the dawn of economic theory and bourgeois economics, Quesnay, the father of the Physiocrats, approached the problem with classical fearlessness and simplicity and took it for granted that total capital exists as a real and active entity. In his famous _Tableau Économique_, so intricate that no one before Marx could understand it, Quesnay demonstrated the phases of the reproduction of aggregate capital with a few figures, at the same time taking into account that it must also be considered from the aspect of commodity exchange, that is as a process of circulation.[60]
