This simultaneous existence of the two equivalents at opposite poles and their simultaneous change of places or mutual alienation presupposes in its turn that seller and buyer enter into relations as owners of equivalents that are on hand. But in the course of time, the process of the metamorphosis of commodities which produces the different forms of money, transforms also the owners of commodities or changes the character in which they appear before each other in the community. In the process of metamorphosis of the commodity the guardian of the latter changes his skin as often as the commodity changes place or as the money assumes new forms. Thus, the owners of commodities originally confronted each other only as commodity owners, but later on they became one a buyer, the other a seller; then each became alternately buyer and seller, then hoarders, and finally rich men. In that manner, the owners of commodities do not come out of the process of circulation the same men that they entered.
