Careful consideration of the discussants' comments provided "matter" for rethinking the theses formulated in the lecture on the need to believe in the power of reason and in a rational order. Some of the discussants' statements reinforced the thesis about the difficulties contemporary psychologists of human development have in researching and explaining development, as well as about certain omissions resulting from the shift of attention from the search for the relationship between theory and empiricism to the benefit of empiricism itself. The presented considerations led to the conclusion about the difficulties that psychological scientists have in recognizing truth and falsehood, good and evil as a consequence of the lack of respect for establishing basic ontological and epistemological assumptions. A chance to overcome the crisis in human development research is provided by a systemic approach and a return to the "classic" - ontogenetic research.
