NO NEED TO SEEK THE CAUSE OF GOOD AS IN THE INTELLIGIBLE THE CAUSE COINCIDES WITH THE NATURE.
Shall we then define the good as the virtue characteristic of each being (as say the Stoics)? In this case, by strictly following (the course of dialectics) we would reduce the Good to being a form and a reason. But, having arrived there, what should we answer if we were asked on what grounds these things themselves are good? In imperfect things, it seems easy to distinguish the good, even though it be not pure; but in intelligible things we may not immediately succeed in discovering the Good by comparison with the inferior things. As there is no evil on high (in the intelligible world), and as excellent things exist in themselves, we find ourselves embarrassed. Perhaps we are embarrassed only because we seek the cause ("whyness") (of the good), whereas the cause ("whyness") is here identical with the nature ("whatness"), as intelligible entities are good in themselves. Nor would we have solved the problem if we were to assign some other cause (of the Good), such as the divinity, to which our reason has not yet forced us to repair. However, we cannot retire, and we must seek to arrive by some other road to something satisfactory.
