A reader of St. Thomas will first encounter analogical naming as a way to account for how some names can be applied to the divine substance. Later on, it becomes apparent that we need to use analogy even to understand ourselves, for insofar as we are spiritual substances, we can only understand ourselves by comparison to sense objects. St. Augustine would remark once that if you can imagine something, it is not God- but for different reasons it is also true to say that if you can imagine someone or something, it is not yourself. Can you imagine what a universal is, or the power and substance that gives rise to it? To say yes only means you have understood neither the universal nor yourself.
The old myths about the gods were in part only attempts to articulate the nature of man. It was idolotry and error to worship the Olympians because we are the Olympians- we are the immortals so beset by folly, vice, infighting, and occasionally greatness.
