I have been reading into the psycho-social literature with my colleague Judy Rose. We have been looking at post-Kleinian work by Winnicott and Bion, particularly concepts such as holding, container-contained. Now the most interesting part of this reading, is that the psychoanalytic writing is about clinical work, and the concepts are ways to think about the work in the psychoanalytic encounter. But Bion suggests that the theory is only useful for about 3 sessions, while the analyst is developing inter-intra-relations (my riff) with the patient. After this time the concepts emerge from the encounter. So what does this mean for adopting a concept? How can a psycho-social methodology work alongside this philosophical work?
