Full Idea
Some philosophers who embrace properties as powers hold that every property is a power (Bird), or that some properties are qualities and some are powers (Ellis; Molnar). The latter include powers which are 'grounded in' qualities (Mumford).
Gist of Idea
Are all properties powers, or are there also qualities, or do qualities have the powers?

A Reaction
I don't like Heil's emphasis on 'qualities', which seems to imply their phenomenal rather than their real aspect. I'm inclined to favour the all-powers view, but can't answer the question 'but what HAS these powers?' Stuff is intrinsically powerful.
