Abstract
This paper aims to show Hegel’s system to be a self-generating and conceptually closed system and, therefore, an idealism. Many readers have agreed that Hegel intends his logic to be a self-generating, closed system, but they assume that the two branches of Realphilosophie, Nature and Spirit, must involve the application of logical categories to some non-conceptual reality external to them. This paper argues that Nature emerges from logic by the reapplication of the opening logical categories to the final category of logic, Absolute Idea, and that the resulting categories are irreducible bipartite compounds that develop into new categories by characteristic forms of self-relation following, roughly, the sequence in logic from Being through Essence. With the determination of Absolute Idea by Concept, Spirit emerges, and it develops through its own characteristic forms of self-relation until Absolute Idea is self-determined. Hence, Realphilosophie is a rigorous conceptual development that goes beyond logic without introducing anything that is not conceptual.
