Abstract

Hegel’s mature system, because of its division into three parts, makes particularly high demands on the argumentative powers when it comes to the demonstration of the necessity of the links between the respective parts of the system. It is a well known fact that the transition from/of logic to natural philosophy is a very critical point in the system, and was already subjected to particular criticism by Schelling as being a weak point in the system. For Hegel, however, the transition from natural philosophy to the philosophy of spirit is also such a critical seam or hinge in his system. The three versions of the Encyclopedia of the Philosophical Sciences provide documentary evidence of his continuous work on the relevant passages. Hegel’s own handwritten notes and drafts, and also the students’ manuscripts of his lectures on “subjective spirit”, provide interpreters with additional information and thus give them more profound insights into Hegel’s efforts to achieve conceptual precision in this area, as well as into an abundance of empirical material that Hegel gathered and subsequently incorporated from contemporary science as it developed.
