A Reaction

I suspect that this neglected distinction is important in discussions of Quine's elimination of the analytic/synthetic distinction. Was Quine too influenced by what is logically necessary, which might shift with a change of axioms?

The 26 ideas with the same theme [different ways in which things must be]:

14680 Logical possibility contains metaphysical possibility, which contains nomological possibility [Salmon,N]
9205 The three basic types of necessity are metaphysical, natural and normative [Fine,K]
15079 'Conceptual' necessity is narrow logical necessity, true because of concepts and logical laws [Lowe]
16533 Logical necessities, based on laws of logic, are a proper sub-class of metaphysical necessities [Lowe]
8261 Maybe not-p is logically possible, but p is metaphysically necessary, so the latter is not absolute [Hale]
15081 A strong necessity entails a weaker one, but not conversely; possibilities go the other way [Hale]
15080 'Relative' necessity is just a logical consequence of some statements ('strong' if they are all true) [Hale]
13721 'Strong' necessity in all possible worlds; 'weak' necessity in the worlds where the relevant objects exist [Sider]
19286 'Absolute necessity' is when there is no restriction on the things which necessitate p [Hale]
19288 Logical and metaphysical necessities differ in their vocabulary, and their underlying entities [Hale]
19290 Absolute necessities are necessarily necessary [Hale]
7800 Analytic truths are divided into logically and conceptually necessary [Girle]
4646 Is 'events have causes' analytic a priori, synthetic a posteriori, or synthetic a priori? [Baggini /Fosl]
9482 If the laws necessarily imply p, that doesn't give a new 'nomological' necessity [Bird]
13244 Relevant necessity is always true for some situation (not all situations) [Beall/Restall]
10933 Physical possibility is part of metaphysical possibility which is part of logical possibility [Rami]
14703 Superficial necessity is true in all worlds; deep necessity is thus true, no matter which world is actual [Schroeter]
14532 A distinctive type of necessity is found in logical consequence [Rumfitt, by Hale/Hoffmann,A]
