Goethe's morphological insight that every animal is one archetypal form, the Typus, varied and transformed across species rather than assembled from separate parts.
The Metamorphosis of Animals in Anthroposophy is the morphological principle, drawn from Goethe's 1820 poem of that name and reconstructed by Rudolf Steiner in his Goethean Science writings of 1883, that the whole animal kingdom expresses a single inwardly mobile archetype, the Typus, that transforms itself from species to species. Goethe arrived at it through two findings. The first was his 1784 discovery of the intermaxillary bone in man, the small upper-jaw bone that closed the supposed gap between human and animal. The second was his vertebral theory of the skull, which read the bones of the head as transformed spinal vertebrae. Steiner treats this not as dead comparison but as a living idea grasped by the eye of the spirit. Today it grounds Goethean zoology, where the animal form is studied as a verb, a continuous shaping, never a finished thing.
The Metamorphosis of Animals is Goethe's answer to a question that classifying science could not reach: what holds the animal kingdom together beneath its endless variety of shapes. His reply was the Typus, one archetypal animal form that does not sit behind the species as an abstraction but works within each of them, transforming organ into organ and creature into creature. Steiner, editing Goethe's scientific writings, recovered this as the founding idea of a science of living form.
In Steiner's Own Words
This was a discovery of the most far-reaching significance. It proved that all members of an organic whole are identical in idea and that "internally unformed" organic masses open up to the outside world in different ways, that it is one and the same thing that opens up at a lower level as the spinal cord nerve and at a higher level as the sensory nerve to the sensory organs that receive, grasp and comprehend the outside world. Every living thing was thus revealed in its power to form and shape itself from within.
What it Means Today
Goethean zoology carries this principle into present practice. The two discoveries Steiner foregrounds remain its anchor points. In the spring of 1784, comparing human and animal skulls in Jena with the anatomist Justus Christian Loder, Goethe found the intermaxillary bone in man, the small upper-jaw bone that Sömmerring, Blumenbach, and Camper had all insisted was absent. He wrote to Herder that he had found "not silver or gold, but something that gives me inexpressible joy, the os intermaxillare in man." The point was never the bone itself. It removed the one anatomical wall that let naturalists treat man as a separate construction, and so it confirmed that one formative force runs through every vertebrate. The second anchor, the vertebral theory of the skull, came to Goethe in 1790 on the dunes of the Lido near Venice, where a cracked sheep's skull showed him the cranial bones as transformed vertebrae. Contemporary Goethean morphologists at the Naturwissenschaftliche Sektion of the Goetheanum in Dornach still work this way, holding the skeleton, as the poem instructs, together with its ligaments and movement rather than as an assembled mass of bone. The animal is read as a process of transformation, the Typus thinking itself into matter. Goethe's study of animal form prepares Steiner's reading of the three animal natures, eagle, lion and cow.
