Abstract

_Purpose._ The authors aim to reveal the influence of philosophical and esoteric principles on the formation and further development of Roberto Assagioli’s concept of psychosynthesis. _The theoretical basis_ of the study is determined by the latest methodological approaches in the study of the relationship between philosophical, psychological, and esoteric approaches in the study of the unconscious and the formation of a harmonious personality. _Originality._ For the first time, a systematic analysis of the anthropological foundations of Roberto Assagioli’s work has been carried out in Ukrainian philosophical literature, the specificity of the connection between esoteric teachings and psychosynthesis has been revealed on the basis of a thorough study of primary sources and biographical evidence of the life and work of the famous Italian thinker. _Conclusions._ Psychosynthesis, which is one of the leading directions of modern psychology, has a rather multicultural philosophical and methodological basis. Its founder Roberto Assagioli, while developing his concept, was influenced by theosophical-esoteric, pragmatic kabbalistic, and Eastern religious concepts and practices. Unlike psychoanalysis, which saw the unconscious as physiological-naturalistic determinants of the human psyche and behavior, psychosynthesis considers the unconscious as a hidden potential for self-development of the individual. Roberto Assagioli went through a long and difficult way to finally form his own concept, which became the basis of the psycho-techniques of disidentification and work with subpersonalities, which help to discover the true transpersonal self, which is the source of human self-improvement. Modern discussions about the relationship between psychosynthesis and various forms of parapsychology once again testify to the synthetic nature of Assagioli’s teaching, which combines various psychotherapeutic practices. This is what gives psychosynthesis a new push for development in the conditions of wars, disasters, loneliness, and related psychological disorders.
