Final answer:
Marx believed that a person's work or creative activity defines who they are. In a capitalist system, workers are alienated from their species being and view themselves as commodities. Marx predicted a global revolution leading to communism, where this alienation would be overcome and creative freedom fully realized.
Step-by-step explanation:
Karl Marx believed that a person's work (i.e., creative activity) made a person who they really are. The central concept here is alienation, where Marx theorized that in a capitalist society, workers become estranged from their species being, or their inherent human potential. This alienation arises because workers sell their labor and are not connected to the products of their work. Consequently, they begin to view themselves and others as commodities, feeling despair due to their reliance on the capitalist system and not by their contributions as individuals.
Marx also foresaw a time when a global revolution would lead to communism, where there would be equality of material resources and a society without economic classes. He envisioned that people would reach their full potential for creativity and peaceful solidarity. Overall, Marx's perspective opposes the commodification of human labor as a determinant of human worth and identity.
