Full Idea
Dispositions should correctly be understood as more than mere possibilities. To say something has a disposition is to say something about how it is actually.
Gist of Idea
Dispositions are not just possibilities - they are features of actual things

A Reaction
To me this is a basic axiom of metaphysics. The word 'power' serves well for the actual embodiment of a disposition. A power gives rise to one or more dispositions. Or one or more powers give rise to a disposition?
