 Three preliminary issues are relevant to almost all discussions of history and the philosophy of history. The first is a set of issues having to do with the "ontology" of history, the kinds of entities, processes, and events that make up the historical past. This topic concerns the entities, forces, and structures that we postulate in describing the historical phenomena, whether the medieval manor or the Weimar Republic, and the theory we have of how these social entities depend upon the actions of the historical actors who embody them. The second issue has to do with the problems of selectivity unavoidable for the historian of any period or epoch. Here we take up the question of how the unavoidable selectivity of historical inquiry in terms of theme, location, scope, and scale influences the nature of historical knowledge. The third issue has to do with the complicated relationship that exists between history, narrative, and collective memory. This topic addresses the point that real human beings make history. And, as Marc Bloch insists (1953), we humans are historical beings, we tell stories about ourselves, and those stories sometimes themselves have major historical consequences. The collective memories and identities of Serb nationalism were a historical fact in the 1990s, and these elements of mythic collective identity led to massive bloodshed, ethnic cleansing, and murder during the violent breakup of Yugoslavia (Judt and Snyder, 2012; Judt, 2006).
