 For his part, Meillassoux advocates not a return to pre-critical metaphysics, but a critique of Critique, which would re-open philosophical access to what he calls the “great outdoors” – i.e., Kant’s “thing in itself” or, to put it in Meillassoux’s terms, the “thing without me.” While conceding that sensory concepts imply a human relation to the world, Meillassoux argues that mathematics offers privileged access to “primary qualities,” thus breaking philosophy out of correlationism. Rather than simply describing what is given in experience, speculative philosophy can venture alongside the physical sciences into an account of the world before human beings existed, which Meillassoux calls “ancestrality.”
