In Hegel’s philosophical system, Nature is the Idea in its external manifestation, in the form of “otherness.” This is widely interpreted as implying that the realm of the Idea extends beyond the boundaries set by the Logic, permeating other parts of the system. On this reading, Nature functions solely as an extension of the Idea, with no intrinsic significance beyond this role. This chapter challenges this interpretation, showing that in Hegel’s system, Nature possesses an independent reality and cannot be reduced to a mere “function” or “mirror” of the Idea. As an autonomous and self-sufficient entity, Nature operates according to its own laws, distinct from the laws of Logic. Thus, what Hegel offers in his Philosophy of Nature is a metaphysical (philosophical) account of the conceptual structure of nature itself, of what it ultimately is. The account of nature that arises from Hegel’s philosophical inquiry into the natural world is not only realistic, it also offers a systematic image of nature in its dynamic development aligned with growing complexity. This underpins Hegel’s emergentist agenda, which differs substantially from the one proposed by traditional Naturphilosophie. Hegel’s version of emergentism aims to demonstrate why a particular set of concepts and principles is sufficient for comprehending natural phenomena at a specific level of complexity and how these concepts and principles logically necessitate the emergence of the succeeding level. This “system of stages” is not propelled by external factors such as divine command or preordination; instead, it operates internally and metalogically, driven by its own inherent logic and principles.
