The role played by Hegel’s Logic within those parts of his “Realphilosophie,” philosophy of nature and philosophy of spirit, is puzzling and controversial. In this essay, I argue against the idea that we should be able to understand his Logic as charting some entirely autonomous domain without any help from the areas of Realphilosophie that presuppose it. This mistake here I take to be a consequence of failing to heed Hegel’s demand that we understand the system of his Encyclopaedia as circular, moreover as containing “circles within circles” such that the circular structure is iterated into its parts, into the parts of those parts, and so on.
