 However, those theorists who defend the political and moral value of reconciliation more often reject the claim that reconciliation requires forgetting. Instead, these defenders generally claim that knowledge and acknowledgement of wrongdoing, as well as recognition of the victims, are crucial to successful reconciliation. Especially in political contexts, knowledge of basic facts is critical because often victims and the broader political community do not know who was responsible for the wrong suffered, nor the extent of violations committed. Acknowledgement refers to the official, public recognition of what happened. This is often needed to counter official denial of wrongdoing or responsibility for wrongdoing (Weschler 1998). The unspoken, Freudian assumption is that suppressed traumas will inevitably reemerge in destructive ways. The more explicit arguments are that the acknowledgement of wrongs and of victims helps heal psychic wounds (van Ness and Strong 2002), enable trust (Gibson 2004), reestablish normative standards for behavior (Walker 2006), and reassert that the victims are indeed members of the moral or political community (Llewellyn and Howse 1999, du Toit 2000).
