 We’ve discussed in the previous section how Lewis aimed to reduce the mental to the nomic. (Or at least much of it; we’ll return to the question of value in section 7.5.) We’ll discuss in the next section his distinctive modal metaphysics. In this section we’ll look at how he attempted to locate the nomic in the Humean mosaic. Lewis’s aim was to show that nomic properties and relations could be located in the Humean mosaic by locating them as precisely and as explicitly as he could. So the location project revealed a lot about these nomic features. We’ll spend the next two subsections looking at the two important parts of this project. Notably, they are two parts where Lewis refined his views several times on the details of the location.
