word of the process of exchange, in short as money, and money in its distinct role of a universal means of payment. In this capacity of a means of payment money appears as the absolute commodity, but within the sphere of circulation and not without it as was the case with hoards. The difference between the means of purchase and the means of payment makes itself unpleasantly felt in periods of commercial crises.104
Originally, the conversion of the product into money in the sphere of circulation appears only as an individual necessity for the commodity owner in so far as his own product has no use-value to him, but has to acquire it first by being alienated. But in order to pay at the expiration of the contract, he must have sold commodities before that. Thus, entirely apart from his individual wants, the movement of the circulation process makes selling a social necessity with every owner of commodities. As a former buyer of a commodity he is compelled to become a seller of another commodity in order to get money not as a means of purchase but as a means of payment, as the absolute form of exchange value. The conversion of commodity into money as a final act, or the first metamorphosis of a commodity as an end in itself which in the case of hoarding seemed to be a matter of caprice on the part of the commodity owner, becomes now an economic function. The motive and essence of sale for the sake of payment becomes from a mere form of the process of circulation its self emanating substance.
In this form of sale the commodity completes its change of position; it circulates while it postpones its first metamorphosis, viz. its transformation into money. On the contrary, on the part of the buyer the second metamorphosis is completed, i. e. money is reconverted into a commodity before the first metamorphosis has taken place, i. e., before the commodity has been turned into money. The first metamorphosis thus takes place after the second in point of time; and thereby, money i. e. the form of the commodity in its first metamorphosis, acquires a new destination. Money or the spontaneous development of exchange value, is no longer a mere
