Sensory Impression/Sense-perception/meaning/Frith: Thesis: we are not the slaves of our senses.
Experience/Frith: experience is not constantly dominated by sensory signals. We could not have hallucinations, but it would not be a good idea:
Problem: Sensory signals are too unreliable. We should not be slaves of our senses. This only occurs in brain damage. For example, when these people see a glass, they have to drink from it.
Fantasy: controlled fantasy saves the brain from the tyranny of the environment.
Imagination/Phantasy/Brain/Frith: 1. How do we know that the model of the world that our brain designs is the right one?
Solution: this is not a real problem: the model does not have to be the right one, it just has to work so that we can influence the world.
2. How does the brain know whether I actually see a face or just imagine one?
Imagination: in a pure representation there are no sensory signals, and thus also no possible error message.
Reality/Frith: reality is always unexpected.
Imagination/Frith: imagination is boring in the long run. E.g. there is no deception in the imagination. A necker cube never veers round.
Creativity/Frith: we create nothing in our head alone.
Solution: first by doodling, writing, sketch, etc.: shifting to the outside.
