Read moreSomewhat at random, I shall pick chapter 7 for a closer look. Tye distinguishes three versions of the view that colors are “mind-independent, illumination-independent properties”, which we frequently see physical objects as possessing. The first is emergentism, according to which colors are “simple qualities” that nomologically supervene on the physical facts: there is a possible world exactly like the actual world physically, but in which nothing is colored. Brute nonreductive physicalism is the same as emergentism, except that colors are said to metaphysically supervene on the physical facts. Hence, on this second view, there is no physical duplicate of the actual world in which nothing is colored. The third position, reductive physicalism, simply identifies colors with physical properties.
