“The ancien regime”, as applied to 18th-century France, always sounds like such a solid proposition. It speaks of arbitrary power, stiffened with protocol, girded by gold, topped by a dusting of icing sugar (you could always spot a noble by their terrible teeth) and utterly stuck in its ways. Until, that is, revolution arrived in 1789 with a clap of thunder to reset the clock so that everything could start over. Yet, as Robert Darnton shows in this enthralling book, the last 50 years of old France were in fact febrile and shifting, rocked by a series of social and political affaires that reached far beyond elite circles, engaging men and women who were more used to worrying whether the cost of bread would rise by another two sous.
Darnton calls this new flexible mood the “revolutionary temper”, by which he doesn’t simply mean that French people eventually became so cross that they embarked on a programme of violent protest that led to the guillotining of the king and queen in 1793. Rather, by “temper” he is referring to “a frame of mind fixed by experience in a manner that is analogous to the ‘tempering’ of steel by a process of heating and cooling”.
