I’ve mentioned Heidegger a twice already on this blog, once in relation to Deleuze and Spinoza, and once in relation to my own work on Being and normativity. Kvond recently posted a question on the former post, asking why I take Deleuze’s reworking of Spinoza’s metaphysics to be a specifically post-Heideggerian one. I think it was fairly clear in that post why I take it to be post-Heideggerian, but I feel that I could reiterate the basic point, and in the course of it examine what it is to do genuinely post-Heideggerian metaphysics.
The phrase ‘post-Heideggerian metaphysics’ is meant to have an important resonance, given that metaphysics is usually taken as the name of that philosophy which came before Heidegger, whose inadequacies he correctly diagnosed and overcame. We are often told that we can either accept Heidegger’s insights regarding Being and metaphysics and abandon metaphysical thinking, or revert to a pre-Heideggerian metaphysics, and that there is no middle ground. To do genuinely post-Heideggerian metaphysics would be to embrace certain of Heidegger’s insights but nevertheless reject his turn away from metaphysics, pursuing metaphysics in a way that is at least partially characterised by Heidegger’s portrayal of it. In short, it would be to pursue a metaphysical project through an explicit concern with Being (and thus, I would add, the question of the meaning of Being).
