 Recall that we said that Humean supervenience is a conjunction of several theses. One of these is a thesis about which perfectly natural properties are instantiated in this world, namely local ones. That thesis is threatened by modern physics. But the rest of the package, arguably, is not. In particular, the thesis that all facts supervene on the distribution of perfectly natural properties and relations does not appear to be threatened. (Though see Maudlin (2007: Ch. 2) for a dissenting view.) Nor is the thesis that perfectly natural properties and relations satisfy a principle of recombination threatened by modern physics. The rough idea of the principle of recombination is that any distribution of perfectly natural properties is possible. This thesis is Lewis’s version of the Humean principle that there are no necessary connections between distinct existences, and Lewis is determined to preserve as strong a version of it as he can.
