A property is essential iff the object would not exist if it lacked that property [Forbes,G]
|
|
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.

From:
Graeme Forbes (In Defense of Absolute Essentialism [1986], 1)
|
|
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.

Trivially essential properties are existence, self-identity, and de dicto necessities [Forbes,G]
|
|
Full Idea:
The main groups of trivially essential properties are (a) existence, self-identity, or their consequences in S5; and (b) properties possessed in virtue of some de dicto necessary truth.

From:
Graeme Forbes (In Defense of Absolute Essentialism [1986], 2)
|
|
A reaction:
He adds 'extraneously essential' properties, which also strike me as being trivial, involving relations. 'Is such that 2+2=4' or 'is such that something exists' might be necessary, but they don't, I would say, have anything to do with essence.

One might be essentialist about the original bronze from which a statue was made [Forbes,G]
|
|
Full Idea:
In the case of artefacts, there is an essentialism about original matter; for instance, it would be said of any particular bronze statue that it could not have been cast from a totally different quantity of bronze.

From:
Graeme Forbes (In Defense of Absolute Essentialism [1986], 3)
|
|
A reaction:
Forbes isn't endorsing this, and it doesn't sound convincing. He quotes the thought 'I wish I had made this pot from a different piece of clay'. We might corrupt a statue by switching bronze, but I don't think the sculptor could do so.
