Single Idea 16200

[from 'How Things Persist' by Katherine Hawley, in 9. Objects / B. Unity of Objects / 3. Unity Problems / b. Cat and its tail ]

Full Idea

Many philosophers believe that sortal predicates are spatially maximal - for example, that no cat can be a proper spatial part of a cat.

Gist of Idea

Are sortals spatially maximal - so no cat part is allowed to be a cat?

A Reaction

This sounds reasonable until you cut the tail off a cat. Presumably what remains is a cat? So presumably that smaller part was always a cat? Only essentialism can make sense of this! You can't just invent rules for sortals.
