ABSTRACT
Bion's attention to the separate worlds of experience of babies and their mothers, and of analysands and their analysts stemmed, at least in part, from his experience as a tank battalion officer during the First World War. Impressed by the high morale of soldiers working together in groups, 1 he sought to use this experience in developing group methods of officer selection during the Second World War, 2 and group methods of treating its hospitalized psychiatric casualties. 3 This doubtless contributed to his running therapy groups at London's Tavistock Clinic after the war was over.
