Full Idea

Actualism ...debars us from admitting into our ontology the merely possible, not only the merely logically possible, but also the merely physically possible.

Gist of Idea

Actualism means that ontology cannot contain what is merely physically possible

A Reaction

This is the big metaphysical question for fans (like myself) of 'powers' in nature. Armstrong declares himself an Actualist. I take it as obvious that the actual world contains powers, but how are we to characterise them?
