In replying to the commentaries, I continue to explore differences between a complexity model of the mind and an intrapsychic one, and elaborate aspects of the complex negotiation process that occurred between my patient, Kerri, and me. Taking up Chefetz's notion that a “change in self-state predicts observed fluctuations in the capacity to mentalize,” I consider ways that self-states in both the patient and analyst fluctuate, influence, and reorganize the unfolding process, including the systemic capacity to mentalize.
