Democracy and Ochlocracy

The concept of Tyranny of the Majority has sometimes been formulated as Ochlocracy--Rule of the Mob, which some have classified as a degenerate form of Democracy.  Now, one dubious aspect of these associations is that, as Aristotle points out, and as has been repeatedly proven throughout History, the use of a mob as a tool of political intimidation is at least as much a feature of Oligarchies as it is one of Democracies.  Furthermore, that the behavior of a mob can be accurately characterized as 'unruly' tends to expose the formulation 'Mob Rule' as oxymoronic, i. e. a mob lacks the capacity for sustained deliberation that ruling requires.  Finally, according to Nietzsche, perhaps the most acute of its critics, the tendency towards degeneracy in Democracy consists in the cultivation of timidity and homogeneity, i. e. the characteristics of a herd of sheep, not those of an angry mob.  So, the possibility that the danger of a Democracy deteriorating into an Ochlocracy seems more an expression of the condescension or fear of an Oligarch than the product of sound analysis.
