[catalogued under 10. Modality / A. Necessity / 3. Types of Necessity]

Full Idea

Necessity is 'relative' if a claim of φ-necessary that p just claims that it is a logical consequence of some statements Φ that p. We have a 'strong' version if we add that the statements in Φ are all true, and a 'weak' version if not.

Gist of Idea

'Relative' necessity is just a logical consequence of some statements ('strong' if they are all true)

A Reaction

I'm not sure about 'logical' consequence here. It may be necessary that a thing be a certain way in order to qualify for some category (which would be 'relative'), but that seems like 'sortal' necessity rather than logical.
