What is a metaphysical allegory?
An allegory is a sort of comparison where one thing symbolically represents a more complicated idea. A metaphysical allegory, therefore, is an allegory that is used to represent the metaphysical, which is the infinite or intangible. A good example of this is the first chapter of the Bible, by which God creates the world in 7 days. It didn’t actually happen that way (science tells us this with certainty), but the Biblical description of the creation of the world is a metaphysical allegory.
