Full Idea
It is not true that everything that there is seeks some single good: each thing has an inclination for its own good, the eye for sight, the body for health, and so on.
Gist of Idea
Everything seeks, not a single good, but its own separate good

A Reaction
Aristotle's pluralism. Elsewhere this pluralism arises from his function argument - that the good of each thing is the successful fulfilment of its function, which is different for each thing. This is basic to virtue theory, and has my approval.
