Goethean science concerns the natural philosophy (German Naturphilosophie "philosophy of nature") of German writer Johann Wolfgang von Goethe. Although primarily known as a literary figure, Goethe did research in morphology, anatomy, and optics. He also developed a phenomenological approach to natural history, an alternative to Enlightenment natural science, which is still debated today among scholars.[citation needed]
His works in natural history include his 1790 Metamorphosis of Plants and his 1810 book Theory of Colors. His work in colour, and his polemics against the Newtonian Optics had a mixed reception from the natural history establishment of the time — under half spoke against Goethe, while a third of natural scientists had favourable reviews of Goethe's colour theory.
