Single Idea 13804

[from 'In Defense of Absolute Essentialism' by Graeme Forbes, in 9. Objects / D. Essence of Objects / 6. Essence as Unifier ]

Full Idea

A property P is an essential property of an object x iff x could not exist and lack P, that is, as they say, iff x has P at every world at which x exists.

Gist of Idea

A property is essential iff the object would not exist if it lacked that property

A Reaction

This immediately places the existence of x outside the normal range of its properties, so presumably 'existence is not a predicate', but that dictum may be doubted. As it stands this definition will include trivial and vacuous properties.
