the circulating commodities appears, therefore, as a movement of money which furthers the exchange of commodities, motionless in themselves. The movement of the circulation process of commodities thus takes on the form of the movement of gold as a medium of circulation, i. e. of the _circulation of money_. Since owners of commodities give the products of their individual labor the appearance of products of social labor by turning one object, viz. gold, into the direct expression of universal labor-time and therefore into money, their own movement by which all of them effect the interchange of the material products of their labor now appears to them as the direct movement of that one object, as the circulation of gold. The social movement itself appears to the owners of commodities partly as an outward necessity and partly as a mere formal intermediary process which enables every individual who puts any use-value into circulation to get other use-values out of it of an equal value. The use-value of commodities comes into play with their disappearance from the sphere or circulation, while the use-value of money as a medium of circulation is in its very circulation. The movement of a commodity in the sphere of circulation is of a transitory kind, while ceaseless motion in that sphere constitutes the function of money. Through this special function which it performs within the sphere of circulation money acquires a new capacity, which we have to consider now more closely. In the first place, we see that the circulation of money forms an endlessly split up movement, since it reflects the splitting up of the process of circulation into an infinitely large number of purchases and sales and the independent separation of the mutually supplementary phases of metamorphoses of commodities. In the small cycles described by money, where the starting and returning points coincide, we do find a return movement, i. e., an actual circular movement, but the fact that there are as many starting points as there are commodities and that the number of these cycles is infinitely large puts them beyond all control, measurement, or computation. The time between the start and the return of a commodity is just as indefinite. Moreover, it is immaterial whether or not such a circuit has been actually described in a given case. No economic fact is more generally known than that one can spend money with one hand without getting it back with the other. Money proceeds from an endless number of points and returns to as many different points, but the coincidence of the starting and returning points is a matter of chance, because in the movement C―M―C the turning of the buyer again into a seller is not a necessary condition. Still less does the circulation of money resemble a movement radiating from a common centre to all points of the periphery and back from the peripheral points to the centre.
