"To prevent possible misunderstandings, let me say this. I do not by any means depict the capitalist and the landowner in rosy colours. But individuals are dealt with here only in so far as they are the personifications of economic categories, the bearers [Träger] of particular class-relations and interests. My standpoint, from which the development of the economic formation of society is viewed as a process of natural history, can less than any other make the individual responsible for relations whose creature he remains, socially speaking, however much he may subjectively raise himself above them."
Karl Marx from his “Preface to the First Edition” for Capital, Volume One
