What problem is Vygotsky tackling in these lectures he called “pedological” (Vygotsky, 2019)? We shall read his writings as a text in itself, somehow detached from the rest of his works, but clearly addressed to those who have already tried to attack the same problems. Two problems are notably raised and discussed in this text. First, how is the phenomenon of emergence observable in child development explained by Vygotsky? Second, how can knowledge of the course of the development of the child (laws and stages/ages) and that of individuals be articulated using the concept of perezhivanie?
