Wokół pojęcia konstruktywizmu

The paper presents a short story of radical constructivism and its applications in the field of Polish humanistic research. The authors claim that it is impossible to establish the coherent definition of radical constructivism due to its variability and changeability. There are rather different radical constructivist positions connected by the common assumptions (for example: the constructivist character of human cognition). The works of the founder of radical constructivism, Ernst von Glasersfeld, are still unknown in the Polish reception, however the authors find the excellent works inspired by the radical constructivist theses, also in the field of literary research.
