While typically unapologetic in expressing admiration, notably Gilles Deleuze admits his concern one time, in passing, that Gilbert Simondon's thought might hide a pernicious kind of ‘disguised moralism’, in which the form of the transcendent (‘God’, ‘Man’, ‘Ideas’) lurks, the enemy of the philosophy of immanence. Might there in fact be an ulterior motive in Deleuze's concern? But might this potential critique invite its own reversal? That is, might Deleuze's accusation be in fact a strategy for teasing out what, perhaps, is unrecognisable as such, but structurally essential for how Simondon constructs his onto-epistemological goals? Moreover, might this Simondonian response, unmasked, not only deflect but anticipate a ‘critique’ like Deleuze's? Extending this question further reveals I believe the implications for Simondon's ‘ethics without morality’, bringing him closer to Deleuze's interpretation of Spinoza. As a result, Deleuze's ‘critique’ invites the question: ‘What exactly is Spinozan in Simondon's ethics?’ Such a question compels our re-evaluation of humanism, its underlying prerogatives, if now in light of its consequences, the re-evaluation of poststructuralism: first, because it is predicated on the critique of the humanistic subject and, second, because ‘poststructuralism’ has come to designate how Simondon's relatedness is determined to Deleuze.
