The illusion theory of this property claims that it is a "virtual property", and exploits the 4+2 structure of its natural concept to claim that it does not exist in nature.
The illusion theory of this property claims that it is a "virtual property", and exploits the 4+2 structure of its natural concept to claim that it does not exist in nature. P.M.S. Hacker's Simple Objectivist view of this claims it is an intrinsic quality of objects.  The dispositionalist account of this, which has roots in the writings of Descartes and Locke, claims that saying something has this is equal to saying it has some other property which makes it appear to have this to the right observer. Landesman wrote about this "and consciousness"; Frank Jackson wrote about the "primary quality view of" this, and Goethe's Theory Of [This] explained it as the interaction between light and dark.  For 10 points, name this phenomenon, seen along the entire visible wavelength from red to violet.
