My article has a dual purpose: on the one hand I will discuss the concept of social community that emerges from the public activity of Ginzburg. I will look at the political practice that Ginzburg sketched out, clarifying how this would become that "politica della memoria" aimed at defending and rebuilding what is `in ruin,' i.e. - and this is also the `duty' that Ginzburg had always assigned to Jewish people - aimed at standing up for all the losers of History, for all the people defeated by `progress.' On the other hand, I will clarify the connection this concept of community has not only with Ginzburg's literary topics, but with the forms of her narrative. I will make clear, in other words, how the idea of community is related to a precise form of novel structure, a structure modified according to the different historical judgments given by Ginzburg on the community-Italy.
