In the decade of 1970s, Ernesto de Sousa while prompting the concepts which had been developed in previous years, called for “a total revolution” which would supposedly have repercussions for all the society’s components. In order to subvert the established norms, Ernesto de Sousa extended conducted under his umbrella artistic processes in political practices, proceeding to a revision of linguistic nomenclatures e.g. through replacing the term artist for aesthetic operator, whereby opening the artworks to a spectator and activating her as their essential component. Those transformations were mostly an attempt to confront the bourgeoisie institution that in its theoretical spectrum incorporated the art market and the fascist regime, both of which persisted until 1974. The program which comprehends those considerations marks several historical moments on national territory, concurrently always seeking to reflect them and to embrace them in the promotion of a free and egalitarian society.
