Single Idea 12144

[filed under theme 9. Objects / D. Essence of Objects / 8. Essence as Explanatory ]

Full Idea

The reasonableness of the essentialist hypothesis will be proportional to the extent that we can, as a result, use a's possession of P to explain a's other properties, ...and there is an inability to explain otherwise why a has P.

Gist of Idea

Essentialism is justified if the essential properties of things explain their other properties

Source

Baruch Brody (Identity and Essence [1980], 6.3)

Book Ref

Brody,Baruch: 'Identity and Essence' [Princeton 1980], p.152


A Reaction

Brody as a rather liberal notion of properties. I would hope that we can do rather more than explain a's non-essential properties. If the non-essential properties were entailed by the essential ones, would they not then also be essential?


The 13 ideas from 'Identity and Essence'

Brody bases sortal essentialism on properties required throughout something's existence [Brody, by Mackie,P]
A sortal essence is a property which once possessed always possessed [Brody, by Mackie,P]
Maybe essential properties are those which determine a natural kind? [Brody]
a and b share all properties; so they share being-identical-with-a; so a = b [Brody]
Indiscernibility is a necessary and sufficient condition for identity [Brody]
Interrupted objects have two first moments of existence, which could be two beginnings [Brody]
Identity across possible worlds is prior to rigid designation [Brody]
De re essentialism standardly says all possible objects identical with a have a's essential properties [Brody]
Modern emphasis is on properties had essentially; traditional emphasis is on sort-defining properties [Brody]
Mereological essentialism says that every part that ensures the existence is essential [Brody]
Essentially, a has P, always had P, must have had P, and has never had a future without P [Brody]
An object having a property essentially is equivalent to its having it necessarily [Brody]
Essentialism is justified if the essential properties of things explain their other properties [Brody]
