This conceptual paper offers an integration and clarification of several constructs that have become prominent in current psychoanalytic thought: inter-subjectivity, multiple selfhood, and the relational unconscious. It is argued that recent theory on multiple selves may be synthesized with the concept of inter-subjectivity. From this viewpoint, multiple selves can be seen as subjectivities that may enter into various forms of intersubjective relatedness. Dynamic unconsciousness occurs when one subjectivity or self-state cannot be translated or formulated by another. Several short clinical anecdotes are offered to illustrate these points.
