About the book: 2015 / "Psychology of Human Capabilities" - a collection of lectures by P. D. Uspensky, one of the founders of the Fourth Way system. These lectures are devoted to the most important issue for this esoteric teaching - human evolution, those development opportunities that everyone has, but which not everyone is ready to take advantage of. The publication also includes a verbatim recording of Uspensky’s meeting with one of the groups of students in London, which took place on September 23, 1937 year. The answers given by Ouspensky during this meeting dealt with some of the difficulties in understanding the basic ideas of the Fourth Way system, the principles and methods of organizing schools, and the importance of rules. The first record of this meeting, checked and corrected by Uspensky in his own hand, is in the memorial collection of P. D. Uspensky in the department of manuscripts and archives of the Yale University Library.
