If the Church lays claim to a spiritual power to which the temporal power of the Empire or the State must remain subordinate, as happened in medieval Europe, or if, as happened in the twentieth-century totalitarian State, legitimacy insists on doing without legality, then the political machine spins in circles with often lethal results; if, on the other hand, as has happened in modern democracies, the legitimating principle of popular sovereignty is reduced to the electoral moment and is dissolved into procedural rules that are juridically fixed in advance, legitimacy runs the risk of disappearing into legality and the political machine is equally paralyzed.
