My favourite interegnatory chapter is the one advancing the argument that the cobblestones of Paris are the guarantor of democracy: if le regime too much offends les miserables, they dig them up for barricades and missiles! The notable fact in that regard is that following the 1968 student riots, the authorities paved over the cobbles of the left bank. (Or so I'm told.)
