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.

There are two sides to men - the pleasantly social, and the violent and creative [Diderot, by Berlin]
|
|
Full Idea:
Diderot is among the first to preach that there are two men: the artificial man, who belongs in society and seeks to please, and the violent, bold, criminal instinct of a man who wishes to break out (and, if controlled, is responsible for works of genius.
|
|
From:
report of Denis Diderot (works [1769], Ch.3) by Isaiah Berlin - The Roots of Romanticism
|
|
A reaction:
This has an obvious ancestor in Plato's picture (esp. in 'Phaedrus') of the two conflicting sides to the psuché, which seem to be reason and emotion. In Diderot, though, the suppressed man has virtues, which Plato would deny.
