g., when it is done for the purpose of lending abroad a certain amount on interest, it depends on circumstances, whether it will be exported in the form of commodities or in that of gold, and if in the latter form, it is due to the specific destination of the precious metals as distinguished from commodities to serve as money. In general, these writers do not consider money in its abstract form, as it is developed within the sphere of simple circulation of commodities, and as it spontaneously grows out of the relation of the circulating commodities. As a result, they constantly vacillate between the abstract forms of money which distinguish it from commodity and those forms of it beneath which are concealed concrete relations, such as capital, revenue, etc.[155] Introduction to the Critique of Political Economy.[156] 1. PRODUCTION IN GENERAL. The subject of our discussion is first of all _material_ production by individuals as determined by society, naturally constitutes the starting point. The individual and isolated hunter or fisher who forms the starting point with Smith and Ricardo, belongs to the insipid illusions of the eighteenth century. They are Robinsonades which do not by any means represent, as students of the history of civilization imagine, a reaction against over-refinement and a return to a misunderstood natural life. They are no more based on such a naturalism than is Rosseau’s “contrat social,” which makes naturally independent individuals come in contact and have mutual intercourse by contract. They are the fiction and only the aesthetic fiction of the small and great Robinsonades. They are, moreover, the anticipation of “bourgeois society,” which had been in course of development since the sixteenth century and made gigantic strides towards maturity in the eighteenth. In this society of free competition the individual appears free from the bonds of nature, etc., which in former epochs of history made him a part of a definite, limited human conglomeration. To the prophets of the eighteenth century, on whose shoulders Smith and Ricardo are still standing, this eighteenth century individual, constituting the joint product of the dissolution of the feudal form of society and of the new forces of production which had developed since the sixteenth century, appears as an ideal whose existence belongs to the past; not as a result of history, but as its starting point.
