Education of the "Greatness of the will" in the works of A.A.Kaelas
One of the schools of Psychology, that continues to single out and consider will as one of the mental processes, was G.I. Chelpanov Psychology. In the late 20s of the last century G.I. Chelpanov, students created their own psychological laboratory, which continued to explore many of the questions of the so-called «old» psychology. The head of this laboratory was A.A. Kaelas (1880-1920), whose scientific work this article is devoted to. The first article was published in 1917 in the journal «Psychology and Children», which was called «the will and its upbringing».
