Full Idea
This book is a plea for recognising potentiality as an explanans in the metaphysics of modality, rather than as something in need of explanation or reduction.
Clarification
An 'explanans' is what does the explaining
Gist of Idea
Potentiality does the explaining in metaphysics; we don't explain it away or reduce it

A Reaction
Something has to do the explaining, and it is obviously much better to have some aspect of the real world do the job, rather than remote abstractions such as laws, possible worlds or Forms. Personally I like the potentiality of 'powers'.
