Single Idea 16425

[filed under theme 10. Modality / A. Necessity / 5. Metaphysical Necessity ]

Full Idea

Strong metaphysical necessities will put constraints on the space of possible worlds that are brute and inexplicable. That's fine for our world, but bizarre for possible worlds. The realm of the possible has no room for such arbitrary constraint.

Gist of Idea

Metaphysical necessity is a bizarre, brute and inexplicable constraint on possibilities

A Reaction

He would say this, given that he wants zombies to be possible, just because he thinks he can conceive of them. Presumably he thinks a raging bonfire with no flames is also possible. His objection here is weak.
