Joe and Rolf discuss the ideas of perceptual psychologist Donald Hoffman, who has argued that our perceptual systems have no access to reality, since evolution is driven by fitness functions, not objective truth. He has also argued that our perception is a user interface (like a desktop on a computer, or a VR headset), and that objects such as the moon don't exist when we are not apprehending them.  Hoffman, Donald.

Everyone has a set of beliefs. Increasingly, it seems like we wonder how so many people can hold opposite or contradictory beliefs -- puzzling if we think there's an objective reality.
