American literature in 1960s and afterwards witnessed the attempt of a group of writers whose experimental fiction offered new aesthetic views. Susan Sontag, as a prominent figure of intellectual and literary circles, is well known for introducing the abilities of the new sensibility of Camp to reflect and transform experience. Sontag’s fictional works—which are much less frequently investigated compared to her world-famous essays and critical works— provide an observation of the world as an aesthetic phenomenon. The present study is an attempt to have a poststructuralist view of the short story “Old Complaints Revisited” based on LuceIrigaray’s concepts of masquerade and mimicry. The psychoanalytic-philosophic reading strategy tries to depict performativity of experience in Sontag’s fiction. This methodology is hoped to reflect the sensationsand the unique experience that the story evokes, concentrating on the subject to show how gendered subjects reflect their own meanings and how cultures play a crucial role in this formulation. The poststructuralist feminist method shows performativity could be regarded at the core of Sontg’s story telling strategy. This could provide a view of mimesis which becomes so integral to the place each individual has within the borders of the limiting authority figures.
