But all these destructive discourses and all their analogues are trapped in a sort of circle. This circle is unique. It describes the form of the relationship between the history of metaphysics and the destruction of the history of metaphysics. [...] there are many ways of being caught in this circle. They are all more or less naïve, more or less empirical, more or less systematic, more or less close to the formulation or even to the formalization of this circle. It is these differences which explain the multiplicity of destructive discourses and the disagreement between those who make them. It was within concepts inherited from metaphysics that Nietzsche, Freud, and Heidegger worked, for example. Since these concepts are not elements or atoms and since they are taken from a syntax and a system, every particular borrowing drags along with it the whole of metaphysics. This is what allows these destroyers to destroy each other reciprocally—for example, Heidegger, considering Nietzsche, with as much lucidity and rigor as bad faith and misconstruction, as the last metaphysician, the last "Platonist." One could do the same for Heidegger himself, for Freud, or for a number of others. And today no exercise is more widespread.
