VIII. Reactionary World Conceptions
> It is really of no avail that we attempt to express directly the nature of a thing. What we are aware of are effects, and a complete account of these effects might possibly encompass the essence of that thing. Vainly do we endeavor to describe the character of a man; we put his deeds and actions together, however, and a picture of his character arises before our eyes. Colors are the actions of light; they are what light does and suffers. In this sense we can expect information from them concerning the nature of light. Color and light are indeed in close relation but we must think of them both as belonging to nature as a whole; for it is nature as a whole that is ready to manifest itself in special ways to the sense of the eye.
