The aim of this article is to discuss the objection of vicious circularity concerning the relation between the Phenomenology of Spiritand the Science of Logic. My argument is articulated in three stages: in the first place, I will provide a historical reconstruction of the debate and I will try to neutralize the objection of vicious circularity; in the second place, I will examine the latest positions of the Hegel-Forschungabout the issue of a possibly reciprocal presupposition between the PhG and the SL; in the third place, I will analyze the meaning of a virtuous circularity, by showing its inner relation to a dynamic conception of systematicity.

This volume brings together studies developed in the context of the 10th Leituras da Lógica de Hegel, held from April 28 to 30, 2026. The contributions are devoted to the second chapter of the First Section of Hegel’s Doctrine of Essence, “The Essentialities or the Determinations of Reflection.” The volume is organized according to the three determinations examined in this section—Identity, Difference, and Contradiction—and seeks to preserve the conceptual movement that guided both the preparatory work of the research groups and the presentations delivered at the meeting. The studies approach this movement from different philosophical problems, interpretive perspectives, and possibilities of contemporary development.
