Context

“It preserves its social character only in that these individuals mutually exchange qualitatively different use-values for the satisfaction of their wants. Under capitalist production they can do so only by means of money. Thus the wealth of the individual is realised as social wealth only through the medium of money. It is in money, in this thing, that the social nature of this wealth is incarnated. — F.E.] This social existence of wealth therefore assumes the aspect of a world beyond, of a thing, matter, commodity, alongside of and external to the real elements of social wealth.” source
