Frank Jackson:
"Perception" (1977)

(Copyright © 2014 Piero Scaruffi | Legal restrictions )
This book is a technical defense of sense datum theory. The immediate objects of perception are mental. To perceive an object is to be in a perceptual state as a causal result of the action of that object.
Color is not a property of material things. Sense-data are not material, they are mental.
Later (in 1982) on epiphenomenal qualia Jackson proposed a famous thought experiement: a color-blind neurophysiologist who knows everything of how the brain perceives colors still cannot know what it feels like to see a color.
