The Separation of Inorganic Conditions

“It is not the unity of living & active humanity with the natural, inorganic conditions of their metabolic exchange with nature and hence their appropriation of nature, which requires explanation or is the result of a historic process, but rather the separation between these inorganic conditions of human existence and this active existence, a separation which is  completely posited only in relation of wage labor & capital.”

Karl Marx, Grundrisse
