Single Idea 12533

[filed under theme 9. Objects / D. Essence of Objects / 13. Nominal Essence ]

Full Idea

We only suppose the being of real essences, without precisely knowing what they are: but that which annexes them still to the species is the nominal essence.

Gist of Idea

Real essences are unknown, so only the nominal essence connects things to a species

Source

John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 3.06.06)

Book Ref

Locke,John: 'Essay Concerning Human Understanding', ed/tr. Nidditch,P.H. [OUP 1979], p.442

A Reaction

Compare Idea 12532. Locke can't quite make up his mind about the role of the 'sort' in our understanding of essence. His most consistent position is (I take it) to reject it entirely, as he did at first. ...Beginning of 3.06.07 confirms this.
