"A Social Theory of the Nation-State: The Political Forms of Modernity Beyond Methodological Nationalism," construes a novel and original social theory of the nation-state. It rejects nationalistic ways of thinking that take the nation-state for granted as much as globalist orthodoxy that speaks of its current and definitive decline. Its main aim is therefore to provide a renovated account of the nation-state's historical development and recent global challenges via an analysis of the writings of key social theorists. This reconstruction of the history of the nation-state is divided into three periods such as: classical (K. Marx, M. Weber, E. Durkheim), modernist (T. Parsons, R. Aron, R. Bendix, B. Moore), and, contemporary (M. Mann, E. Hobsbawm, U. Beck, M. Castells, N. Luhmann, J. Habermas). For each phase, it introduces social theory's key views about the nation-state, its past, present and future.In so doing this book rejects methodological nationalism, the claim that the nation-state is the necessary representation of the modern society, because it misrepresents the nation-state's own problematic trajectory in modernity. And methodological nationalism is also rejected because it is unable to capture the richness of social theory's intellectual canon. Instead, via a strong conception of society and a subtler notion of the nation-state, "A Social Theory of the Nation-State" tries to account for the 'opacity of the nation-state in modernity'.
