@Putin33 Are you saying "the law" and "morality" are the same thing? "Right" vs. "wrong" is a different matter than "legal" vs. "illegal." At any rate, the process you described shows “legal” vs. “illegal” gradually lining up with “right” and “wrong” over time. But, what is the *source* of how we judge “right” and “wrong”? Surely it is the laws, not the morality, that is changing. The laws are the “useful fiction”, and the morality is the inherent characteristic of humans. And it is this moral sense that leads us to value human life over rhino life.
And, sweet merciful navel-gazing krikey, red is defined as a wavelength *irrespective of how the wavelength is received by the eye.* It is measured in fractions of a meter. It is usually defined over the range of 620nm to 740nm. When an object emits or reflects light in this range, it has the property "red" EVEN IF NOBODY SEES IT AT ALL, IT IS RED. Gamma rays, and infrared, are also colors THAT WE CANNOT SEE (though bees can see some of that shit), and in fact *all* of them are electromagnetic radiation.
This "ask a mathematician" chap has discussing red as an experience, rather than red as a property. The experience is entirely subjective. The property that elicits that experience is a real thing in the world. Your earlier post denied the reality of red as a property of an object, which is incorrect. The red jellybean is red even when there is no red light to reflect. Your line of reasoning confusing experience with reality would lead us to believe that the universe stops existing when we close our eyes.
