10. Modality / A. Necessity / 1. Types of Modality
Dispositionality has its own distinctive type of modality [Mumford/Anjum]
     Full Idea: We contend that dispositionality involves a non-alethic, sui generis, irreducible modality.
     From: S.Mumford/R.Lill Anjum (Dispositional Modality [2011], 1)
     A reaction: This is a lovely bold proposal, and seems to be supported by Werner Heisenberg, in Idea 17534.
10. Modality / A. Necessity / 2. Nature of Necessity
Necessity can attach to statement-names, to statements, and to open sentences [Quine]
     Full Idea: Three degrees necessity in logic or semantics: first and least is attaching a semantical predicate to the names of statements (as Nec '9>5'); second and more drastic attaches to statements themselves; third and gravest attaches to open sentences.
     From: Willard Quine (Three Grades of Modal Involvement [1953], p.158)
10. Modality / A. Necessity / 11. Denial of Necessity
Necessity is in the way in which we say things, and not things themselves [Quine]
     Full Idea: Necessity resides in the way in which we say things, and not in the things we talk about.
     From: Willard Quine (Three Grades of Modal Involvement [1953], p.176)
     A reaction: This is a culminating idea of Quine's thoroughgoing empiricism, as filtered through logical positivism. I would hardly dare to accuse Quine of a use/mention confusion (his own bête noir), but one seems to me to be lurking here.
