Abstract
How ought the historian to reconcile themselves philosophically with the fact of evental contingency and of its relationship to structural determination? Does the existence of contingent causation undermine the very concept of historical necessity, or do the two instead in dialectical entanglement? In this essay, I engage with the problem of historical contingency from a transcendental-materialist perspective informed by the work of Slavoj Žižek, tendering a philosophically serious response to the famous Pascalian conundrum of Cleopatra’s nose and its challenge to structuralist accounts of historical causation. The position associated with Laplace – that is to say, that the course of history would be entirely predictable were one provided with a complete account of initial conditions – is firmly rejected. Instead, I revive Althusser’s attempt to craft a theory of ‘aleatory materialism’, in which the determinative power of structural forces nevertheless leave space for the radical and unpredictable transformation of a situation by the chance crystallisation of events and encounters. In this effort, I recruit conceptual architecture not only from the fields of historiography and philosophy, but also quantum physics, psychoanalysis, and mathematics.
