Although Carl Jung’s ideas about the practice of psychotherapy were worked out by the mid-1920s, the implications of his ideas for clinical work have taken a long time to sink in. The general public is probably better acquainted with Jung’s most general theories. From the point of view of intellectual history, however, it can be striking how more recent schools, such as self-psychology and object relations, have been unknowingly recycling proposals that Jung first put forward long ago.
