Single Idea 16080

[filed under theme 9. Objects / B. Unity of Objects / 3. Unity Problems / d. Coincident objects ]

Full Idea

A strong intuition shared by many philosophers is that some things that are in fact identical might not have been identical.

Gist of Idea

Is it possible for two things that are identical to become two separate things?

A Reaction

This flies in the face of the Kripkean view that if Hesperus=Phosphorus then the identity is necessary. I don't think I have an intuition that some given thing might have been two things - indeed the thought seems totally weird. Amoeba? Statue/clay?


The 6 ideas from Lynne Rudder Baker

Constitution is not identity, as consideration of essential predicates shows [Rudder Baker]
Clay is intrinsically and atomically the same as statue (and that lacks 'modal properties') [Rudder Baker]
Is it possible for two things that are identical to become two separate things? [Rudder Baker]
The constitution view gives a unified account of the relation of persons/bodies, statues/bronze etc [Rudder Baker]
The clay is not a statue - it borrows that property from the statue it constitutes [Rudder Baker]
Statues essentially have relational properties lacked by lumps [Rudder Baker]
