Guy Ernest Debord was a French theorist, writer, filmmaker, hypergraphist and founding member of the groups Lettrist International and Situationist International. In broad terms, Debord's theories attempted to account for the spiritually debilitating modernization of the private and public spheres of everyday life by economic forces during the post-WWII modernization of Europe. Alienation, Debord postulated, could be accounted for by the invasive forces of the 'spectacle'—"a social relation between people that is mediated by images." Central to this school of thought was the claim that alienation is more than an emotive description or an aspect of individual psychology; rather, it is a consequence of the mercantile form of social organization which has reached its climax in capitalism. Debord committed suicide, shooting himself in the heart at his property on November 30, 1994.
