Full Idea
Modality has a special ontological category: it consists neither in objects (possible worlds theory) nor in properties (predicate modifier view), but items I have called 'modes', ..which can be hard/soft/rigid/pliable binding of objects to properties.
Clarification
'Modality' concerns what is necessary or possible
Gist of Idea
Modality is not objects or properties, but the type of binding of objects to properties

A Reaction
As so often, McGinn is very persuasive. Essentially he is proposing that modality is adverbial. He associates the middle view with David Wiggins.
