Mescalin raises all colors to a higher power and makes the percipient aware of innumerable fine shades of difference, to which, at ordinary times, he is completely blind. It would seem that, for Mind at Large, the so-called secondary characters of things are primary. Unlike Locke, it evidently feels that colors are more important, better worth attending to, than masses, positions and dimensions (p. 27).
What intrigues me about his remarks is that by this alteration in color, attention is drawn to color and drawn away from the "primary qualities" of VS. I have already argued that even in ordinary VS, it is literally color that is primary, not the quantitative or quantifiable magnitudes that it contains by virtue of the juxtaposition of different colors, because without the color, there is no VS at all (and by "color" I am including black and white). There are no lines, no surfaces, no shapes--in short, no geometry!
