I have never been convinced that Nietzsche heralded, as Heidegger claimed, “the death of metaphysics”, but instead thought that he demonstrated, indeed, its very inevitability. Yet a student today could be excused for thinking that that word “metaphysics” was some kind of vile academic invective. In Porter I recently found a reassurance that I am not alone in this suspicion:
Nietzsche cannot be assumed to have passed from a philosophical naivete (as if in a “precritical” period) to some emancipated, free-spirited thinking that definitively outgrew the theoretical problems (and not just the philological materials) that he had encountered early on. I doubt that Nietzsche believed in grand emancipatory possibilities at any point in his career. His readings of the Presocratics (Heraclitus, Parmenides, or Democritus) put this beyond doubt for the early period: what these reflections show is something about the inescapably, not just of the category of the subject, but of its idealism– which is always bound up, for Nietzsche, with the subject’s infinite capacity for delusion. What we learn is that Nietzsche’s inquiries into ancient philosophy do not reveal a premetaphysical thinking that points to a region beyond metaphysics, as is frequently held. On the contrary, Nietzsche’s early writings reveal the inescapability of metaphysical thinking. […] But as Nietzsche says quite plainly in both phases, early and late, ‘It is absolutely impossible for the subject to want [and hence, to be able] to see and known something beyond itself: knowledge and being are the most contradictory spheres there are.’ The ‘subjective concept’ is ‘eternal’: we can never accede to a region ‘beyond the wall of relations’ by which we are conditioned, for beyond these lies merely ‘a mythical primordial ground of things'”.
