Single Idea 15086

[filed under theme 10. Modality / A. Necessity / 2. Nature of Necessity ]

Full Idea

Maybe peaceful co-existence between absolute logical necessity and absolute metaphysical necessity can be secured, ..and absolute necessity is their union. ...However, a truth would then qualify as absolutely necessary in two quite different ways.

Gist of Idea

Absolute necessity might be achievable either logically or metaphysically

A Reaction

Hale is addressing a really big question for metaphysic (absolute necessity) which others avoid. In the end he votes for rejecting 'metaphysical' necessity. I am tempted to vote for rejecting logical necessity (as being relative). 'Absolute' is an ideal.
