Freud's view of the ego as Januslike, the one component of the psychic system turned toward the external world yet partly unconscious, should have insured its centrality in clinical interventions. However, history and experience do not bear this out. It is argued that a core part of the change process in analysis lies in the modifications that occur in ego functioning, making it necessary to carefully consider the role of the ego in clinical technique. Numerous clinical examples are presented to show the manner and significance of such an approach.
