One hundred years after the publication of Freud’s Beyond the Pleasure Principle (Freud, 1920), anti-Semitism is understood as the realization of the (self-)destructive force in its group form of the anti-group (Nitsun, 1996). Foulkes’ secrecy about the impacts of the German National Socialism(NS)-anti-group in his life (unlike Freud and Elias), as well as the libidinal idealization of the group, can be understood as a post-traumatic defence. But, as Nitsun (1996) has demonstrated, the creative potential of the anti-group can help to develop the group if it is analysed by the group, and can also be demonstrated by this example: the analysis of the traumatic effects of the NS-annihilation-anti-Semitism on the history of group analysis may reveal its hidden prophetic and rabbinical traditions in its foundation matrix. In this respect we can think of every group analytical session as a sign that Auschwitz did not win.
