William James influenced Carl Jung's theoretical development, particularly through James's book 'The Varieties of Religious Experience'. Jung's emphasis on fundamental subjective experience in his own work 'Psychology and Religion' drew on James's ideas. The article examines how James's dynamic psychology shaped Jung's later writings, including 'On the Nature of the Psyche'. Jung's acquaintance with James led him to move away from psychoanalysis and shaped his views on religious experience and the concept of the unconscious.
Analytical psychology has increasingly engaged with drug-related research, moving beyond a purely negative portrayal. This review updates an earlier integrative review and finds that studies at the intersection of analytical psychology and drug research are no longer scarce. The selected studies fall into two main categories: psychedelics and addictions. The most studied substances are ayahuasca and alcohol. Methodologically, the research is dominated by essays and conceptual studies, hermeneutic and heuristic investigations, case studies or clinical cases, and phenomenological research. The paper considers reciprocal contributions between the two fields and outlines possibilities for future investigations.
