Whilst the concept of the subject has been called into question by many diverse approaches within contemporary political and social theory, there remains a focus upon agency, now attributable to reformulated subjectivities or assemblages. I query the persistence of this grammar of agency and ask whether politics can do without a ‘scene of the subject’. Spinoza’s philosophy, in particular, his conception of conatus, has inspired and offered some basis for rethinking agency. I examine two such prominent positions and argue that (...) ultimately neither captures the political promise of Spinoza’s philosophy. Configuring a concept of morphology to analyse this scene, my argument detaches the conatus from a narrow focus upon human desire, and focuses attention upon the scene of the subject as it folded into a wider complex body. My approach also returns a study of power to the discussion: the conatus is the power to persist, but it is also a differential force and site of conflict. By placing the spotlight on the scene of subjectivity in this way, the contemporary political theorist avoids the false antinomy between agency and structure, whilst continuing to track the production and composition of subjectivity in new political forms.
