It is customary to think of marriage as the end of freedom, and some refer to their spouses as “old ball-and-chain.” The notion of family life typically implies constraints, responsibilities that interfere with one’s goals and freedom of action. While this is true, especially when the marriage is one of convenience, what we tend to forget is that these rules and obligations are no different, in principle, than those rules that constrain behavior in a game. Like all rules, they exclude a wide range of possibilities so that we might concentrate fully on a selected set of options.
