Single Idea 16531
[filed under theme 10. Modality / A. Necessity / 5. Metaphysical Necessity
]
Full Idea
By 'metaphysical' necessity I mean necessity of the strongest possible kind - absolute necessity - and I take it to be an objective kind of necessity, rather than being something mind-dependent.
Gist of Idea
'Metaphysical' necessity is absolute and objective - the strongest kind of necessity
Source
E.J. Lowe (What is the Source of Knowledge of Modal Truths? [2013], 1)
Book Ref
-: 'Mind' [-], p.1
A Reaction
See Bob Hale for the possibility that 'absolute' and 'metaphysical' necessity might come apart. I think I believe in metaphysical necessity, but I'm uneasy about 'absolute' necessity. That may be discredited by the sceptics.
