Book excerpt: With particular reference to Deleuze, and drawing on Spinoza, Nietzsche and Bergson, Simone Bignall attends to a minor tradition within Western philosophy to argue that a non-imperial concept of social and political agency and a postcolonial philosophy of material transformation are embedded within aspects of poststructuralist social philosophy.Postcolonial Agency complements and balances the attention given by postcolonial theory to the revitalisation and recognition of the agency of colonised peoples. It offers new conceptual scaffolding to those who have inherited the legacy of colonial privilege, and who now seek to responsibly transform this historical injustice.
