Single Idea 14633

[filed under theme 9. Objects / D. Essence of Objects / 9. Essence and Properties ]

Full Idea

On a friendly reading of Quine, there is nothing to make the difference between a table's being contingently plastic and its being essentially plastic.

Gist of Idea

How do we tell a table's being contingently plastic from its being essentially plastic?

Source

Frank Jackson (Possible Worlds and Necessary A Posteriori [2010], 5)

Book Ref

'Modality', ed/tr. Hale,B/Hoffman,A [OUP 2010], p.261


A Reaction

This is, of course, the dreaded modern usage of 'essential' to just mean 'necessary' and nothing more. In my view, there may be a big problem with knowing whether a problem is necessary, but knowing whether it is essential is much easier.


The 4 ideas from 'Possible Worlds and Necessary A Posteriori'

Quine may have conflated de re and de dicto essentialism, but there is a real epistemological problem [Jackson]
How can you show the necessity of an a posteriori necessity, if it might turn out to be false? [Jackson]
How do we tell a table's being contingently plastic from its being essentially plastic? [Jackson]
An x is essentially F if it is F in every possible world in which it appears [Jackson]
