[I just wrote this: I was glad to make use of last week’s study I did on colors to help explain how the sciences are an applied philosophy, but there are also other applied philosophies -Ken]
Goethe’s study on colors expanded Newton’s rainbow to include parts that Newton missed as Goethe’s approach was different than Newton’s.
He saw Newton’s rainbow as a subset of his own – and he was correct.
Goethe’s ideas have led to great progress in the visual arts, which is why you will always learn more about color in art classes than in science classes: Goethe’s ideas are far richer than Newton’s, which were limited.
However, Newton was more correct in his formalizing of wavelengths; he had a mathematical idea regarding colors and set out to prove it and he succeeded. But it was a limited case. That limited case is all that the sciences needed. But the sciences are one example of an applied philosophy. The arts benefited from applying Goethe’s philosophy of colors.
Yet, modern sciences have also benefitted from Goethe’s ideas. New thoughts in cognitive science follow the line of thinking stemming from Goethe rather than Newton. But it took 200 years for that. But in the intervening 200 years, Newton and Goethe’s color ideas ran down separate conceptual tracks, one down the line of physics in the sciences and the other down the line of the arts.
