Full Idea
It is objected to dispositionalism that without the principle of least action, or some general principle of equal power, the specific dispositional properties of things could tell us very little about how these things would be disposed to behave.
Clarification
'Least action' says nature always takes the shortest route
Gist of Idea
Without general principles, we couldn't predict the behaviour of dispositional properties

A Reaction
Ellis attempts to meet this criticism, by placing dispositional properties within a hierarchy of broader properties. There remains a nagging doubt about how essentialism can account for space, time, order, and the existence of essences.
