Darwinism and evolutionary theory have a bad track record in political theory, given their entanglements with fin-de-siècle militarist imperialisms, racialized hierarchies, and eugenic reformism. In colonial contexts, however, Darwinism had an entirely different afterlife as anticolonialists marshaled evolutionist frameworks to contest the parameters of colonial rule. This article exhumes just such an evolutionary anticolonialism in the political thought of Aurobindo Ghose, radical firebrand of the early Indian independence movement. I argue that Ghose drew on a nuanced reform Darwinism to criticize British imperialism and advance an alternative grounded in the Indian polity’s mutualism. Evolutionism formed a conceptual ecosystem framing his understanding of progress—national, civilizational, and spiritual—and reformulating the temporal and conceptual coordinates of the liberal empire he resisted. The article thus exposes the constructiveness of anticolonial politics, the hybridity of South Asian intellectual history, and the surprising critical potential of Darwinism in colonial settings.
