Abstract
In his book Powers (2003), George Molnar argues against Dispositional Monism by presenting a posteriori reasons to believe in the existence of actual categorical features. In this paper I argue that either Molnar’s project is misdirected, since the properties he concentrates on are most possibly irrelevant for the debate between Dispositional Monism and Property Dualism, or, granted that the properties he chooses are indeed relevant, his arguments cannot prove that they are categorical without begging the question against Dispositional Monism.
