This paper derives from an interest in murder. This interest began through reading fictional narratives which ceaselessly stage and restage scenes of murder; but it has also become clear that a range of theoretical texts are no less preoccupied with the basic question, ‘Why kill?’. In particular, the three theorists I shall discuss here, Freud, Girard and Levinas, directly address the question of murder, its causes and consequences. In each case, the theoretical question turns out to depend upon a minimal (...) core narrative in which the stakes of murder are crystallized; rival theoretical accounts are thus also bound up in a competition of stories. As this paper traces a common concern from Freud's Totem and Taboo, through Girard's La Violence et le sacré, to Levinas's Totalité et infini, the question ‘Why kill?’ gets entangled with the dynamics of storytelling and the issue of what it means to do theory.
