Gold and silver, in their capacity of money, being by conception universal commodities, assume in their capacity of world money the form adapted to a universal commodity. To the extent to which all commodities are exchanged for them, they become the transformed impersonation of all commodities and, therefore, universally alienable commodities. Their function of serving as the embodiment of universal labor-time is realized more and more as the interchange of matter produced by concrete labor embraces increasing parts of the world. They become universal equivalents to the extent to which the series of particular equivalents which constitute their spheres of exchange, increases. Since in the sphere of world circulation commodities unfold their own exchange value on a universal scale, they assume the form of world money when transformed into gold and silver. As commodity owning nations are thus turning gold into money by their diversified industry and universal trade, industry and trade appear to them only as a means of getting money out of the world market in the shape of gold and silver. Gold and silver, as world money, are, therefore, as much products of the universal circulation of commodities as they are means of widening its sphere. Like chemistry which grew up behind the backs of the alchemists who tried to find a way of making gold, so do the sources of world industry and world trade spring up behind the backs of the owners of commodities, while they are hunting for the commodity in its magic form. Gold and silver help to create the world market by anticipating its existence in their conception of money. That this magic effect of the precious metals is by no means confined to the period of infancy of capitalist society but is a necessary outgrowth of the perverse conception which the representatives of the commodity world have of their own work in society, is shown by the extraordinary influence exerted in the middle of the nineteenth century by the discovery of new gold fields.
