Abstract
In this chapter, we consider a posthumanist critique of international law in relation to the material world. Our perspective on posthumanism and international law is framed by a monument of Edward Gibbon Wakefield, the so-called ‘founding father’ of the colony of South Australia. Centering the monument in our dialogue, we discuss two types of materialism: New materialism and historical materialism. We argue that an engagement with new and old materialism opens possibilities for a critical engagement with posthumanism. Central to this critical engagement are themes of materiality, settler colonialism, agency, and exploitation – themes that are key for understanding the operation of international law. By identifying where the materialist theories differ, and also where they converge, we ultimately seek to identify the utility of a posthumanist critique for destabilising international law’s imperialist, capitalist, racialized and patriarchal structures.
