Sigmund Freud. A famous psychiatrist, creator of the theory of psychoanalysis, whose name is known even to those who have never read his works. At one time, Sigmund Freud's idea about the influence of the sexual instinct on the psyche and the development of human society produced the effect of a bomb exploding. The theory of the unconscious, which influences all our actions and deeds, and of sexual attraction as the main driving force of the individual and society as a whole, still causes controversy in the scientific community, but it is impossible to deny that Freud’s teaching on psychoanalysis made an invaluable contribution to the development of all world psychology. In his work “Psychopathology of Everyday Life,” Freud discusses the mental mechanism of forgetfulness. Why do well-known poetic lines fall out of memory or are replaced by new ones? By what principle are neighbors' surnames and street names suddenly replaced by consonant ones? How do childhood memories replace “similar” memories? In his work “On Dreams,” Freud returns to one of his favorite topics: he analyzes and dissects the symbolism of dreams. The publishing layout of the book is saved in PDF A4 format.
