The “grey zone” is a term that was coined by Primo Levi for discussing Jewish collaboration with the Nazis in the camps and ghettos. It denotes to a “zone” where a clear cut distinction between completely inhumane murders and utterly righteous victims is impossible and invalid. In Dr. Goldberg’s talk, he will track the very complex grey zones of identifications as reflected in the victims’ writings during and after the Holocaust. He will suggest that these aspects should be considered very seriously for understanding Jewish history in the Holocaust and thereafter. A new methodology that combines history and psychology (but not as psychohistory) is essential for revealing these important aspects of modern Jewish history.
