Foucault and Spinoza: philosophies of immanence and the decentred political subject

Deleuze has suggested that Spinoza and Foucault share common concerns, particularly the notion of immanence and their mutual hostility to theories of subjective intentionality and contract-based theories of state power. This article explores these shared concerns. On the one hand Foucault's view of governmentality and its re-theorization of power, sovereignty and resistance provide insights into how humans are constituted as individualized subjects and how populations are formed as subject to specific regimes or mentalities of government. On the other, Spinoza was concerned with how humans organized themselves into communities capable of self-government. In particular, his idea of immanent causality was crucial because central to his ideas of freedom and power. We argue that Spinoza's approach to power and causality prefigures ideas developed by Foucault in his theory of governmentality, especially with respect to his biopolitical rethinking of power and resistance
