All things which have ends have also virtues and excellences by which they fulfil those ends. And that to which an end is appointed has also an excellence? Need I ask again whether the eye has an end?

It has.

Yes.

And the ear has an end and an excellence also?

True.

And the same is true of all other things; they have each of them an end and a special excellence?

That is so.

Well, and can the eyes fulfil their end if they are 34 wanting [C]in their own proper excellence and have a defect instead?
