Michel Foucault described the present epoch as being one of space. Some of his notions of space are found in his theories on heterotopias—disturbing places of segregated otherness—which Foucault adapted to describe temporal paradigms within a social framework. This study analyzes the duality of opposing temporal planes that are presented as the empirical world and the metaphysical realm, as they inform the heterotopic space within Alban Berg’s opera Lulu. The objective is to expand on the ambiguous meaning of heterotopia and to view Berg’s opera through the seminal lens of Foucauldian theory.
