the analytic enterprise as centrally involving an effort on the part of the analyst to track the dialectical movement of individual subjectivity (of analyst and analysand) and intersubjectivity (the jointly created unconscious life of the analytic pair—the analytic third)
Ogden defines the intersubjective field operationally as the ‘analytic third’ — the co-created unconscious life of the analytic pair — positioning its dialectical tracking as the central task of psychoanalysis.
