Single Idea 19293

[filed under theme 10. Modality / C. Sources of Modality / 6. Necessity from Essence ]

Full Idea

The point of the essentialist theory is not to provide a reductive explanation of necessities. It is, rather, to locate a base class of necessities - those which directly reflect the natures of things - in terms of which the remainder may be explained.

Gist of Idea

Essentialism doesn't explain necessity reductively; it explains all necessities in terms of a few basic natures

A Reaction

My picture is of most of the necessities being directly explained by the natures of things, rather than a small core of natures generating all the derived ones. All the necessities of squares derive from the nature of the square.
