There are no colors, sounds, or smells out there in the world. This does not mean that there is no world, for indeed there is: the world just is. It has no properties until it is experienced. At any rate, not properties like color, smell, and sound. I see a panorama, a field of vision, but it is not identical with what arrives at my senses. It is a reconstruction, a simulation, a presentation of what my senses receive. An interpretation, a hypothesis.

Tor Norretranders, The User Illusion, 1991
