Nationalism, the state of mind in which the individual’s supreme loyalty is owed to the nation-state, remains the strongest of political emotions. As a historical phenomenon, it is always in flux, changing according to no preconceived pattern. In The New Nationalism, Louis Snyder sees various forms of nationalism, and categorizes them as a force for unity; a force for the status quo; a force for independence; a force for fraternity; a force for colonial expansion; a force for aggression; a force for economic expansion; and a force for anti-colonialism.
