Abstract

The paper presents scientific portrait of the famous Polish scientist, the last representative of the famous Lviv-Warsaw logical-philosophical school, a great friend of Ukraine, Professor Andrzej Grzegorczyk, who died two years ago. In addition to his main passion – mathematical logic, in which he has the world-class results. Andrzej Grzegorczyk studied ethics and philosophy, in particular in such its sphere, which he called “rationalism, opened to values”. It is briefly described his studies in that area, which is often called the “philosophy of education”, although in many cases it should say rather the “philosophy in education”. This research sphere is undeservingly considered as a peripheral one in his work. In fact, it is of prime importance for the development of the theoretical bases of pedagogy. In particular, his scientific program of anthropological description and based on this description the program developed by him deserve the special attention.
