Because I am in agreement with the major points of Jill’s response to my paper, I will only highlight those aspects that need further emphasis. In response to Jill’s question of what we gain clinically by my different way of understanding the therapeutic action of interpretation and internalization, I suggest that the concept of permeable boundaries helps us understand when and why interpretations become meaningful. I argue that interpretations become meaningful only when the “we” of the relationship penetrates both partners in the dyad. In other words, there must be a simultaneous experience of permeable boundaries that metaphorically opens a portal between patient and therapist in order for interpretations to become mutative. The paper then discusses how such a permeable boundary evolves in a psychoanalytic treatment.
