The current thesis works on Hannah Arendt s The Origins of totalitarianism by analyzing its characters, who could not be more varied: Jews, anti-Semites, artists, intellectuals, businessmen, politicians, adventurers, charlatans, heads of families, assassins and leaders like Hitler and Stalin. In work of such weight where complex issues like anti-Semitism, imperialism, and totalitarianism take place, it seems unlikely that the many human types involved could be considered under common terms. The thesis arguments that Arendt manages to do so by considering such differences less determinant than a common trace shared by all those men: the ever-growing incapacity to discern fiction from reality. Thus, the thesis works on what seems to be a powerful anthropological argument with inevitable implications to theory of history.
