Among the challenges facing 21st century psychoanalysis, the need to better integrate the intrapsychic and interpersonal perspectives and traditions is of considerable importance. The French psychoanalyst Jean Laplanche's work is one example of a body of 20th century psychoanalytic theory that has untapped potential for meeting this challenges. Using a variety of examples, I attempt to illustrate this potential and describe some extensions of Laplanche's views that might broaden their utility.
