The signifier ‘black skin’ both fixes identity and signifies its undoing in paradoxically opening up this realm of fantasy, a factor less explored by Fanon than by more recent commentators on his work such as Bhabha, relating to visual culture and art. ‘In the objectification of the scopic drive, there is always the threatened return of the look; in the identification of the Imaginary relation, there is always the alienating other (or mirror) which crucially returns its image to the subject; and in that form of substitution and fixation that is fetishism there is always the trace of loss, absence.’ A paradox ensues whereby blackness becomes a signifier of that which needs to be made invisible, but is also negatively desired (Art and Psychoanalysis by Maria Walsh).
