Monism and qualitativism

This paper is about the relation between two venerable and revisionary metaphysical doctrines: Monism and Qualitativism. Monism says, roughly, that reality is in some sense one. Qualitativism says, roughly, that reality contains no facts about particular objects, but is rather purely qualitative. I distinguish various versions of these two doctrines, and in each case argue that proponents of the Monist doctrine should instead embrace a corresponding Qualitativist doctrine. I conclude that Monism culminates in Qualitativism.
