Single Idea 14751

[filed under theme 9. Objects / B. Unity of Objects / 3. Unity Problems / b. Cat and its tail ]

Full Idea

Burke argues that Tib (the whole cat apart from its tail) goes out of existence when the tail is lost. His essentialist principle is that if something is ever of a particular sort (such as 'cat') then it is always of that sort. Tib is not initially a cat.

Gist of Idea

Tib goes out of existence when the tail is lost, because Tib was never the 'cat'

Source

report of Michael Burke (Dion and Theon: an essentialist solution [1994]) by Theodore Sider - Four Dimensionalism 5.4

A Reaction

This I take to be a souped up version of Wiggins, and I just don't buy that identity conditions are decided by sortals, when it seems obvious that sortals are parasitic on identities.


The 8 ideas from 'Dion and Theon: an essentialist solution'

Persistence conditions cannot contradict, so there must be a 'dominant sortal' [Burke,M, by Hawley]
The 'dominant' of two coinciding sortals is the one that entails the widest range of properties [Burke,M, by Sider]
'The rock' either refers to an object, or to a collection of parts, or to some stuff [Burke,M, by Wasserman]
Tib goes out of existence when the tail is lost, because Tib was never the 'cat' [Burke,M, by Sider]
Sculpting a lump of clay destroys one object, and replaces it with another one [Burke,M, by Wasserman]
Burke says when two object coincide, one of them is destroyed in the process [Burke,M, by Hawley]
Maybe the clay becomes a different lump when it becomes a statue [Burke,M, by Koslicki]
Two entities can coincide as one, but only one of them (the dominant sortal) fixes persistence conditions [Burke,M, by Sider]
