Single Idea 14101

[filed under theme 10. Modality / C. Sources of Modality / 1. Sources of Necessity ]

Full Idea

Fine says a truth is necessary when it is a logical consequence of the essential truths, but maybe it is a consequence of the essential truths together with the basic grounding laws (the 'Moorean connections').

Gist of Idea

Are necessary truths rooted in essences, or also in basic grounding laws?

Source

Gideon Rosen (Metaphysical Dependence [2010], 13)

Book Ref

'Modality', ed/tr. Hale,B/Hoffman,A [OUP 2010], p.133


A Reaction

I'm with Fine all the way here, as we really don't need to clog nature up with things called 'grounding laws', which are both obscure and inexplicable. Fine's story is the one for naturalistically inclined philosophers.

An 'intrinsic' property is one that depends on a thing and its parts, and not on its relations [Rosen]
The excellent notion of metaphysical 'necessity' cannot be defined [Rosen]
Facts are structures of worldly items, rather like sentences, individuated by their ingredients [Rosen]
Explanations fail to be monotonic [Rosen]
Things could be true 'in virtue of' others as relations between truths, or between truths and items [Rosen]
Figuring in the definition of a thing doesn't make it a part of that thing [Rosen]
'Bachelor' consists in or reduces to 'unmarried' male, but not the other way around [Rosen]
An acid is just a proton donor [Rosen]
Are necessary truths rooted in essences, or also in basic grounding laws? [Rosen]
