Abstract: Not only does Hoffman claim that we do not see reality as it is, but that unperceived brains, trees and moons do not exist. His “interface theory of perception” is a peculiar blend of metaphorical ontology (objects are icons, space-time is a desktop) and mathematical modelling (the game-theoretical argument that fitness trumps truth. Conflating abstractions with concrete experience, evolution is used to refute everything (including evolution itself. Hoffman’s sweeping iconoclasm then lands where it took off: addressing the problem of consciousness. After arguing against reality, he will tell us what it is.
