Capitalism reorganises personal consumption to conform to the commercial principles of market exchange; commodity fetishism transforms a cultural commodity into a product with an economic "life of its own" that is independent of the volition and initiative of the artist, the producer of the commodity. What Karl Marx critically anticipated in the 19th century, with "The Fetishism of Commodities and the Secret thereof", Guy Debord interpreted and developed for the 20th century—that in modern society, the psychologic intimacies of intersubjectivity and personal self-relation are commodified into discrete "experiences" that can be bought and sold. The Society of the Spectacle is the ultimate form of social alienation that occurs when a person views his or her being (self) as a commodity that can be bought and sold, because he or she regards every human relation as a (potential) business transaction. (See: "Entfremdung", Marx's theory of alienation)
