In August 1648 Mazarin and Anne of Austria arrested the popular parlementaire Broussel. Retz, then coadjutor of Paris, went to the Palais-Royal offering to calm the crowd and was mocked by courtiers who dismissed the unrest. That humiliation helped turn him from would-be mediator into the Fronde's organizer, a case of a regime converting a potential ally into a rebel leader through contempt at the moment it most needed him.
Retz argues that the rights of peoples and the rights of kings never agree so well as in silence. Authority rests on an unspoken veil, and once the Parlement began publicly debating the limits of royal power, that veil was torn and could not be restored. Openly questioning the foundation of an order is itself the revolution, before any force is used.
Retz holds that everything in politics has a decisive moment, and the masterpiece of good conduct is to recognize and seize it. Timing counts for more than strength. The same move that wins at the moment of maximum confusion fails a day later, once opponents have regrouped or the crowd's passion has cooled.
Retz's maxim is that one never leaves ambiguity except to one's own detriment. Keeping a position undefined preserves options and lets several factions each believe you are theirs, so any explicit commitment loses some allies for certain. Irresolute figures like Gaston d'Orléans, however, show the opposite danger: people who refuse ever to commit end up trusted by no one and are discarded.
