The aim of the paper is an attempt to show that the Thomistic theory of person and the original idea of personal relations built on it become the basis for decisions in the field of pedagogy in the view of consistent Thomism. Mieczysław Gogacz, the founder of this version of Thomism, treating pedagogy as a philosophical science, points to the necessary dependence of upbringing and education on theses resulting from human philosophy, ethics and social security. A properly formulated theory of person is the basis for pedagogy in the current of realist philosophy. This version of Thomism continually emphasises the close dependence of all subsequent assertions on the recognition of existence as an act of individual being which is the basis of all further actualities and manifestations of being. In the case of the human being, the personal act of existence and its manifestations subject the personal relations that result from the coherence of the approaches to metaphysics, philosophy of man and, consequently, ethics. In consistent Thomism, it is the concept of the person and personal relations that define pedagogy.
