Roberto Assagioli

His published work in English includes four books and many monographs published as pamphlets as well as numerous lectures and papers in Italian that remain unpublished but which are being translated into English and posted online.[https://kennethsorensen.dk/en/sitemap/] His approach to psychosynthesis emphasized the possibility of progressive integration (that is, synthesis) of the personality, as well as the integration of the personality with the Higher Self from which it is derived.
“Psychosynthesis is a ''dynamic'' conception of psychic life as a struggle between a multiplicity of disparate, often conflicting forces, and a unifying Center that aims to master and harmoniously organize them.”[https://kennethsorensen.dk/en/from-psychoanalysis-to-psychosynthesis-2/]
In addition, Assagioli’s work has been shown to be effectively applicable in such fields as psychotherapy and treatment, medicine, education, organizational development, community development, spiritual life, and personal self-improvement.
Author Piero Ferrucci has said, “As far as I know, Roberto Assagioli is the only individual who has participated personally and actively in the unfurling of two distinct and fundamental revolutions in twentieth-century psychology.The first revolution was the birth of psychoanalysis and depth psychology in the beginning of the century: Assagioli, then a young medical student, presented his MD dissertation on psychoanalysis, wrote in the official ''Jahrbuch'' side by side with Freud and Jung, and was part of the Zurich Freud Society, the group of early psychoanalytical pioneers. The idea of unconscious processes in the mind made a lasting impression on him, an impression which he later developed into a variety of hypotheses well beyond the boundaries of orthodox psychoanalysis. The second revolution in which Assagioli participated was the creation of humanistic and transpersonal psychology in the 1960’s. A. H. Maslow was the pioneer of these new developments. The main idea was simple: rather than focusing on pathology in order to define the human being (as psychoanalysis had all too often done), or on the structural similarities between the human and the animal nervous system (as behaviorism suggested), the humanistic and transpersonal point of view, while not denying the findings of the other schools, put the main emphasis on the organism’s striving for wholeness, on the human being’s potential for growth, expansion of consciousness, health, love and joy.” Provided by Wikipedia
