Single Idea 10952

[from 'Metaphysics' by Aristotle, in 26. Natural Theory / B. Natural Kinds / 1. Natural Kinds ]

Full Idea

The kind that is common to both horse and ass and which most nearly comprises them happens not to have a name, but can safely be presumed to be both, i.e. the horse-ass or 'mule'. ...A mule does not come from a mule.

Gist of Idea

Unusual kinds like mule are just a combination of two kinds

A Reaction

[second part at 1034b04] Does ancient Greek have a word for 'mule' - it sounds as if it doesn't. Nice chicken-and-egg problem. Must a natural kind be derived from a natural kind? No. Gold does not derive from gold.
