The Hierarchical Structure of Reality in Plato's System

In Plato's system, there wouldn't be angels, but there would be sort of forms. It's unclear and debated whether Plato believed that the gods were actual deities or just symbolic of various forms. But regardless, Plato still structures reality in this hierarchical form. The further you go down the chain, you're moving towards non being. And as we know, because it is a participatory system, true being is thought is idea.
