The notions of difference and indifference that I have been trying to propose as methodological tools for a reading of Joyce's texts cannot avoid being sexualised. It is therefore necessary to examine bisexual motives of undifferentiation in Finnegans Wake especially. I shall refer only obliquely to the long tradition of psychoanalytic¹ discussion of a concept which Freud avowedly took from his friend Fliess, in order to concentrate on Joyce's strategic use of the term. Bisexuality has repeatedly been presented as an apotropaic fantasy whose aim would be to ward off threats of castration through the illusory picture of a fusion between male and female genital organs. The concept would thus mean a dream of completeness, bypassing sexual difference, reuniting what 'sexuality" must needs separate. Such is the case, for instance, with the familiar figure of Ovid's Hermaphrodite, an androgynous being composed of two complementary halves, a chimera of imaginary unification.
