'Tarcza Arystotelesa' by Miroslaw Zarowski is a book of great value, nonetheless bringing about serious difficulties for the reader. The article aims at delivering a philosophical justification for some of those difficulties, and tries to point out relations which connect the book with contemporary problems and notions, such as metaphysics, model of theoretical knowledge, postmodernism, deconstruction, rhetoric, and hermeneutics. The book does not refer explicitly to those notions, or does so in the specific manner, by employing some codes. The article refers broadly to the earlier book of this author, 'Tozsamotnosc. Skazenie natury ludzkiej w filozofii Kartezjusza'.
