Heidegger often says that Ereignis gives Man unto his essence. This follows from the fact that Ereignis is essentially the structural relation between Dasein and reality. To understand this, one has to appreciate two things: a) that the relation does not involve any particular Dasein or group of Dasein, but rather the very structure of Dasein as that being which opens up a horizon (or clearing) within which entities can appear to it, and b) that insofar as it is the structure of beings as a whole, Heidegger thinks that Ereignis is the very structure of reality itself. What this enigmatic statement means is that reality, in and of itself, necessarily involves the possibility of something like Dasein. What Dasein is (or the essence of Man) is not something that has contingently emerged within the world, even if the fact that there are any particular Dasein is contingent. This is the crux of Heidegger’s renowned anthropocentrism: there can be a world without Man, but not without the possibility of something like him. This is correlationism writ large, insofar as the very structure of the correlation (the relation of Man and reality) is not only taken to be a facet of the real structure of the world (or reality), but to be the only such facet that we can know.Wouldn't correlationism require that the earth, not just a world, be contingent on Dasein?
