16. Goethe as Thinker and Investigator

Only someone who sees the absolute correctness of our findings can understand Goethe's colour theory. Any reflection about what a perception like light or colour might be in addition to the entity as which it manifests was completely foreign to Goethe's nature. For he knew what the powers of intellectual thinking were. Light was given to him as sensation. When he then wanted to explain the connection between light and colour, that could not occur through speculation, but only through an archetypal phenomenon, by his seeking out the necessary determining factor that must join light in order for colour to arise. Newton also saw colour arise in connection with light, but he then only thought speculatively about how colour arises out of light. It lay in his speculative way of thinking to do so; but not in Goethe's way of thinking, which was objective and rightly understood itself. Therefore, Newton's assumption that “light is composed of colored lights” had to appear to Goethe as the result of unrightful speculation. He considered himself justified only in expressing something about the connection between light and colour when some determining factor joins in, and not in expressing something about the light itself by bringing in a speculative concept. Therefore his statement: “Light is the simplest, most undivided, most homogeneous being that we know. It is not a composite.” Any statements about the composition of light are, indeed, only statements of the intellect about one phenomenon. The powers of the intellect, however, extend only to statements about the connection of phenomena.
