Slavery contracts
Guy and Doll have agreed that Guy will act as Doll directs, and that Doll is entitled to use force or punishment to get Guy to do as she directs if he ever demurs or falls short. Guy has contracted to be Doll’s slave. Such contracts are familiar from fiction and from history; and some people may have familiarity with them in contemporary life. It is common for philosophers to argue that such contracts are impossible.
