Alfred Adler, one of the founders of psychoanalysis, was the first to wonder why stutterers so often strive to appear on stage, and cripples so strive to participate in sports competitions. These reflections led him to the discovery of a mechanism of overcompensation in the personality structure, within which it is not the presence of abilities, but their deficiency that pushes a person to great achievements. For what? What is the real reason for these actions? Alfred Adler found the answer to this question on the pages of the diary of F. Nietzsche, a great patient of a psychiatric clinic, who spent most of his life in the twilight of consciousness, and only the will to power was capable of awakening in him the greatness of genius. Sigmund Freud believed that the leading force for man is the desire for pleasure. Viktor Frankl made the desire to search for meaning fundamental to man, and only Alfred Adler saw the will to power and understood that it was this dark force that propels man to great achievements. This book is dedicated to the history of megalomania, its triumph and fall.
