Whereas the romantic Surrealists can maintain notions of self and other in which the double threatens the self in a hysterical cat-and-mouse duel, in contemporary society the commoditisation of identity robs these romantic tropes of their proximity to death, promoting instead the immortality of the self. As Freud says in ‘The Uncanny’, once primitive beliefs are surmounted, the double shifts from having been an assurance of immortality to becoming the uncanny harbinger of death. Our mediatised culture tends to promote the former infantile fantasies while foreclosing on their death-tinged elements. In Oh Charlie Charlie Charlie, the uncanny double becomes a sign of immortality in which the self endlessly replicates itself (Art and Psychoanalysis by Maria Walsh).
