Freud's repression of Judaism and its cultural markers from the published “Rat Man” case history has been noted but never satisfactorily explained. This elision can be interpreted using Freud's suggestion that the paradigmatic “rat” represents (among other things) a circumcised penis marking an intergenerational, covenantal exchange. When read against the case study as originally published, Freud's process notes for the Rat Man's treatment (the only set of such notes on a published case that Freud didn't destroy) suggest that Freud chose to sanitize the published version of explicitly Jewish content, thus repeating a pattern of absence as a marker of debt. This debt only grows more tortuous and powerful the longer it remains unpaid. This system of elision in the Rat Man suggests that Freud understood deferral and denial to be built into the Jewish system of piety. Thus, it would seem that Freud used the Rat Man case history to explore Judaism through its repression; Freud's relation to and interpretation of Jewish values are revealed as a primary, if unconscious, subject of the text.
