The narratives of Grossman and Levi are used as applications of the method of the participatory observa-tion, introduced in sociology and anthropology by Malinowski. This method consists in placing the research-er in a social situation, making him interact with the other actors, in order to extract data for analysis. Grossman’s and Levi’s masterpieces may help to describe the concentration universe, which is – according to Hannah Arendt – a central characteristics of totalitarianism. Our two “social researchers” (Grossman and Levi) descend (unwillingly) into the abyss, the concentration camp, ending up being part of the social group that lived in that situation. Manipulation, violence and alienation are the key factors which determined the chance of survival or death in the concentration camp.
