Jacques Lacan in his paper "The Mirror Stage as Formative of the I Function as Revealed in Psychoanalytic Experience" proposes the theory of imaginary identification and revises it several times in his later works. Louis Althusser in his theory of interpellation and Slavoj ?i?ek in his theory of ideology refer to Lacan and imaginary identification. They all discuss the relationship between the subject and the other, which can be traced back to Hegel’s master-slave dialectic. Making a genealogical enquiry from Hegel to Lacan and then to Althusser and ?i?ek focusing on the dialectical relationship between the subject and the imago reveals that the subject’s imaginary identification with the other is not necessarily alienating, but varies in form with the subject, namely, the empty subject’s otherization, the occupied subject’s objectification and the split subject’s negative identification. The dialectical relations between the subject and his imago would shed light on analyzing the psychology in the representation of self and other in transcultural writing.
