17572 | Actuality proves possibility, but that doesn't explain how it is possible [Inwagen] |
Full Idea: A proof of actuality is a proof of possibility, but that does not invariably explain the possibility whose existence it demonstrates, for we may know that a certain thing is actual (and hence possible) but have no explanation of how it could be possible. | |
From: Peter van Inwagen (Material Beings [1990], 12) | |
A reaction: I like this, because my project is to see all of philosophy in terms of explanation rather than of description. |
15377 | Definite descriptions pick out different objects in different possible worlds [Fitting] |
Full Idea: Definite descriptions pick out different objects in different possible worlds quite naturally. | |
From: Melvin Fitting (Intensional Logic [2007], 3.4) | |
A reaction: A definite description can pick out the same object in another possible world, or a very similar one, or an object which has almost nothing in common with the others. |
17579 | Counterparts reduce counterfactual identity to problems about similarity relations [Inwagen] |
Full Idea: Counterpart Theory essentially reduces all problems about counterfactual identity to problems about choosing appropriate similarity relations. That is, Counterpart Theory essentially eliminates problems of counterfactual identity as such. | |
From: Peter van Inwagen (Material Beings [1990], 14) |
17590 | A merely possible object clearly isn't there, so that is a defective notion [Inwagen] |
Full Idea: The notion of a merely possible object is an even more defective notion than the notion of a borderline object; after all, a merely possible object is an object that definitely isn't there. | |
From: Peter van Inwagen (Material Beings [1990], 19) |
17591 | Merely possible objects must be consistent properties, or haecceities [Inwagen] |
Full Idea: Talk of merely possible objects may be redeemed in either maximally consistent sets of properties or in haecceities. | |
