Relation et effectivité chez Hegel, Kant et Aristote

After an examination of the concept of relation in Kant (Critique of pure Reason) and of relatives in Aristotle (Metaphysics, Categories), I compare and contrast Hegel’s Logic of essence, especially the cognate notion of actuality, with Kant and Aristotle. Aristotle’s relatives are not discussed by Hegel in the Logic of essence because the systematic place of Aristotle’s philosophy, with its speculative key concept of energeia, is the heart of the Logic of the Concept. I conclude by showing that for Hegel relation to other is not the final word because it cannot account for self-relation, let alone exhaust the explanation of it.
