Abstract
Wolicka's book on Being and Sign, which deals with semiotics of John of St. Thomas, can serve as a typical model of the approach to the Thomistic philosophy as it is practiced by the KUL's School of Philosophy, namely, "in its close cooperation between the chairs of metaphysics, history of philosophy, and methodology of science." Following the tradition of KUL's school of philosophy, the author treats "the problematics of signs as a typical boundary problem which contains several different theoretical points of view, and especially the metaphysical, noetic and logical one."
