A Reaction

[She cites Alan Sidelle 1989 for this view] I disagree mainly with number 2), since I take dispositions to be key intrinsic features of nature, and I interpret dispositions as modal properties.


The 11 ideas with the same theme [necessity comes from linguistic conventions]:

For each necessity in the world there is an arbitrary rule of language [Wittgenstein]
If natural necessity is used to include or exclude some predicate, the predicate is conceptually necessary [Harré/Madden]
Having a child is contingent for a 'man', necessary for a 'father'; the latter reflects a necessity of nature [Harré/Madden]
A key achievement of Kripke is showing that important modalities are not linguistic in source [Soames]
If necessity rests on linguistic conventions, those are contingent, so there is no necessity [Hale]
If truths are necessary 'by convention', that seems to make them contingent [Sider]
Conventionalism doesn't seem to apply to examples of the necessary a posteriori [Sider]
Necessary a posteriori is conventional for necessity and nonmodal for a posteriority [Sidelle, by Sider]
To know empirical necessities, we need empirical facts, plus conventions about which are necessary [Sidelle]
Conventions can only work if they are based on something non-conventional [Fogelin]
Modal Conventionalism says modality is analytic, not intrinsic to the world, and linguistic [Thomasson]
