  Now, for Platonists only intelligible entities can account for order which amounts to goodness. A Platonic Form, for instance, is responsible for the ordered existence of the physical things it is the Form of. A soul too accounts for the existence of living things, such as animals. Since the world has an order of its own as a single well-ordered whole, there must be such an intelligible entity that accounts for the world's order, wherein its goodness or orderliness lies (kosmos). Being the source of this comprehensive goodness, this must itself be surpassingly good (frs. 16.14–15, 19, 20).  Platonists tended to identify this principle with the Form of the Good in the Republic (508e), which is the source of all being. It was also traditional among them to think of this principle as a divine one or unit—God.
