L'être entre «positivité pure» et «milieu médiatisant». Réflexions sur quelques notions centrales dans «Der Thomismus als Identitätssystem» de Gustav Siewerth

The philosophy of Gustav Siewerth is exceptionally difficult to enter into, a fact which is reflected by the current state of research into this thinker, whose ideas still remain largely unexplored and unexplained. In this article, I therefore pursue a rather modest goal, namely, to introduce the reader briefly to some fundamental concepts of Siewerth's thought. This is done through a close reading of some thirty pages taken from chapter X, section 6 of Siewerth's early work, Der Thomismus als Identitätssystem. This section, entitled, "Die Transzendenz durch die Struktur der Teilhabe", is at the very end of the book and summarizes its principal points.
