Full Idea
Power Monism: all properties are powers. Categoricalism: all fundamentals are categorical. Dualism allows both types. I defend Mixed Monism - that there is a single class of fundamental properties that are at once powerful and categorical.
Gist of Idea
Rather than pure powers or pure categoricals, I favour basics which are both at once

A Reaction
This is the main dilemma for the powers ontology - of how powers can be basic, if there needs to be some entity which possesses the power. But what possesses the powers of an electron? I like Williams's idea, without being clear about it.
