This article makes visible some of the premises that underlie Rosi Braidotti's use of (political) myth. Focusing on some well-known characteristics of postmodernity, as well as the development of a new philosophy of subjectivity, I account for the divergence between Simone de Beauvoir, who thought of myth as a severe hindrance to the subject-becoming of women, and postmodern feminists, such as Donna Haraway and Braidotti, who represent a more affirmative stance. Through pinning down both similarities and differences between Haraway and Braidotti, I demonstrate that postmodern feminists might still promote mythmaking for dissimilar reasons. I argue that Braidotti, in contrast to Haraway, approaches myth from a horizon partly shaped by an anti-rationalist or 'demonic' philosophical tradition, whose chief representative is Friedrich Nietzsche. By studying the argument delivered by the latter in defence of myth, I extract a conceptual distinction between the 'Apolline' and the 'Dionysiac' aspects of mythmaking, by which it becomes possible to further qualify Braidotti's philosophy of political myth.
