Single Idea 12975

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

Full Idea

That gold is a metal which resists cupellation and is insoluble in aquafortis is a distinct idea, for it gives us the criteria or definition of 'gold'. But it is not a perfect idea, because we know too little about cupellation and actions of aquafortis.

Gist of Idea

We have a distinct idea of gold, to define it, but not a perfect idea, to understand it

A Reaction

This connects the 'perfect idea' of something with knowing its active substance, and hence its essence. See Idea 12976 for the connection between perfect ideas and definitions.
