Platonic Dispositionalism

In this paper I argue that if one subscribes to dispositionalism — the view that natural properties are irreducibly dispositional in character — then one ought to favour a Platonic view of properties. That is, dispositionalists ought to view properties as transcendent universals. I argue for this on the grounds that only with transcendent universals in play can two central dispositionalist platitudes be accounted for in a satisfactory way. Given that dispositionalism is becoming an increasingly influential view in the metaphysics of science, my argument, if successful, suggests that Platonism will see something of a revival in contemporary metaphysics. This new kind of Platonism is shown to have some striking metaphysical and epistemological consequences.
