the goods impossible, and delivery has to be postponed for a certain time; e. g., when the use of a house is sold for one month, the use-value of the house is delivered only at the expiration of the month, although it changes hands at the beginning of the month. Since the actual transfer of the use-value and its virtual alienation are separated here in point of time, the realization of its price occurs also after its change of place. Finally, the difference in the seasons and in the length of time required for the production of various commodities brings about a situation where one tries to sell his goods, while the other is not ready to buy; and with the repeated purchases and sales between the same commodity owners the two ends of sale fall apart according to the conditions of production of the respective commodities. Thus arises a relation of creditor and debtor between the owners of commodities which, though constituting the natural foundation of the credit system, may be fully developed before the latter comes into existence. It is clear that with the extension of the credit system, and, consequently, with the development of the capitalist system of production in general, the function of money as a means of payment will extend at the expense of its function as a means of purchase and, still more, as an element of hoarding. In England, e. g., money as coin has been almost completely banished into the sphere of retail and petty trade between producers and consumers, while it dominates the sphere of large commercial transactions as a means of
As the universal means of payment money becomes the universal commodity of all contracts, at first only in the sphere of circulation of commodities.106 But with the development of this function of money, all other forms of payment are gradually converted into money payments. The extent to which money is developed as the exclusive means of payment indicates the degree to which exchange value has taken hold of production in its depth and breadth.107
The volume of money in circulation, as a means of payment, is determined in the first place, by the amount of payments, i. e. by the
