Freud's "analytic pact," as the final therapeutic model he evolved (1937), (1940), places the fundamental rule in a two-person structural framework that operates in a continuum between the inner reality and outer reality of both patient and analyst as these come to center in the analytic situation.

To Freud's basic definition of psychoanalysis as related to resistance and transference, a third component is added, the collaboration that has been a feature of the treatment since the beginning.
