A convention can outlive its original meaning and still do useful work

The argument

A second argument for this position concedes the history and denies that it governs the present. Advocates accept that the practice originated in arrangements that treated a wife as subsumed into her husband's household, and argue that this tells us about its origin rather than about what it now means to those who follow it. Proponents point out that many conventions are like this: they are retained after the belief that produced them has gone, and come to mean only what current participants take them to mean. On this account continuing a practice is not the same as endorsing the reasoning that first established it. Supporters add that the convention continues to do practical work independent of its history. A single household surname simplifies dealings with schools, clinics, landlords, airlines and officials, makes family relationships legible without documentation, and spares children the question of whose name they carry. Advocates argue that these are modest benefits rather than decisive ones, but that they are real, and that a practice offering them to people who are free to decline it is reasonably described as harmless. Proponents conclude that the burden lies with those who say otherwise. On this view the charge against the practice is that it must carry a meaning its participants disclaim, and advocates hold that meanings are not inherited automatically: a convention means what it is understood to mean by those who use it. Supporters argue that the honest answer to why women still change their names is therefore that a great many of them simply want to, and that the practice has become a tradition rather than a hierarchy.

Premises

Counter-arguments

Critics argue that meanings are not purely a matter of individual intention, since others read the practice and draw conclusions from it regardless of what the couple intend. They also note that the practical benefits described are available through other arrangements, including a shared hyphenated name, which does not require one party to give theirs up. A further reply is that the appeal to continuity cannot explain the asymmetry, because an inherited convention stripped of its original meaning would be expected to lose its direction as well.

Rejecting the premises

[Rejecting P1] Framing the origin as merely historical understates how recently the legal and social subsumption of wives was in force. [Rejecting P2] Conventions that retain their original form in only one direction have arguably retained their original meaning too. [Rejecting P3] The same practical benefits are obtainable from a hyphenated or newly chosen shared name, so they do not favour this convention in particular. [Rejecting C] If a convention means what participants take it to mean, it also means what observers take it to mean, and those readings are not the couple's to control.
