Full Idea
Empedocles says that Fire, Water, Air and Earth are four elements, and are thus 'simple' rather than flesh, bone and bodies which, like these, are 'homoeomeries'.
Clarification
A homoeomery has all of its parts identical
Gist of Idea
Fire, Water, Air and Earth are elements, being simple as well as homoeomerous
Source

A Reaction
The translation is not quite clear. I take it that flesh and bone may look simple, because they are homoeomerous, but they are not really - but what is his evidence for that? Compare Idea 13208.
