ABSTRACT
This chapter reviews the approach to group psychotherapy of Hugh Mullan, MD. It shows how Hugh Mullan's work foreshadowed that of many contemporary practitioners of psychotherapy, and how his ideas continue to enrich theoretical development in the field. Subjectivity, mutuality, and non-rational experience are reviewed here to illuminate the confluence between Hugh Mullan's and contemporary thinking on the topics. Hugh Mullan never used it, but he did refer to "mutuality" extensively. Rationalists emphasize the primacy of reason, while irrationalists argues that the human intellect is limited and imperfect, and that there are other ways of finding the truth such as faith, love, and imagination. Mullan and Iris Sangiuliano questioned Freud's and his associates' deep grounding in scientific pragmatism and positivism. The challenge by new schools of psychotherapy to the views of the early classical psychoanalysts, they said, corresponded to changes taking place in science with the development of the Quantum Theory and Relativity.
