This might be the most transcendent capacity of consciousness, and the most terrifying: that in the world of the mind, we can construct models of the real world built upon theories of exquisite internal consistency; that those theories can have zero external validity when tested against reality; and that we rarely get to test them, or wish to test them. Just ask Ptolemy.
In its clinical manifestation, we call this tendency delusion. In its creative manifestation, we call it art — the novel, the story, the poem, the song are each a model, an imagistic impression of the world not as it is but as the maker pictures it to be, inviting us to step into this imaginary world in order to better understand the real, including ourselves.
