Chapter 22 introduces the concept of morphology, the study of form which attends to both the uniqueness of individual manifestations of life and the invariable laws which underpin them. Rather than forming a single theory, Goethe’s extensive reflections on morphology emerged in different contexts and run throughout his oeuvre. The chapter examines the most significant stages in Goethe’s engagement with morphology, from his search for the Urpflanze (primeval plant) in Sicily to his development of Anschauung (intuition) as a method, and positions him in relation to other thinkers, above all Wolff and Kant.
