Not only Goethe's poetry but his science is Spinozistically motivated. Convinced of the oneness of nature, he approached it with a certainty to discover in it oneness, and his discovery of the os intermaxtllare in man, which influenced the development of comparative anatomy, is one of the by-products of his Spinozistic sentiments. In his theory of the metamorphosis of the plants, which he expounded scientifically and poetically, he also expressed a good deal of Spinozism. Spinoza enabled him to read the various pages of nature as one book. Goethe respected Kant and may be described as a Kant scholar, but he was a Spinoza adherent. His world-picture is Spinozistic and not Kantian.
