[QUOTE="briggart, post: 9419600, member: 6805135"] That seems wild. Also wrong. From the original paper: This is not how human vision works. Wavelength differences are important, but also the absolute wavelength matters. Now, previously the author explained how basic physical properties cannot be defined in absolute terms, but only through relative differences, e.g. we cannot define a positive electric charge in an absolute way, but only by comparing its behavior to that of a negative charge, so I understand why the focus is on relative differences. But even assuming this to be true, wavelength is in itself a differential property (e.g. the separation between two consecutive amplitude maxima), so the claim that a purely physical description of experience is untenable doesn't seem very solid, at least based on how it is explained in this paper. I'm not familiar with philosophy, certainly not with modern developments, so it's possible there are more in depth discussion of the issue which account for my objection above, but that really seems wrong to me.
