16. Goethe as Thinker and Investigator

Only in a separate chapter on chemical colour theory does he go on to colors that are fixed, that are connected with objects. If, in the physiological colour theory, the question is answered as to how colors can come to manifestation at all, and, in the physical colour theory, the question as to how the colors come about under external conditions, so Goethe responds here to the problem of how the corporeal world manifests as colored.
