Why You Have a Fixed Surname

Permanent inherited surnames are not ancient, and they were very rarely adopted because anybody wanted one. They were imposed, by decree, over centuries, against resistance, and sometimes assigned on the spot by a registering official who wrote down whatever he had chosen.

The reason is administrative and it is the same reason every time. A state cannot tax, conscript or prosecute somebody it cannot name twice with confidence. Local naming worked perfectly well locally (everybody in the village knew which John was meant, whether by his father, his trade, his farm or his appearance) and it is useless to an official two counties away compiling a list. A patronymic, which changes every generation, is transparent and completely unusable as a key. Iceland still uses one, which is why its phone directories are ordered by first name.

The same logic produced house numbers. Habsburg numbering in the 1770s was introduced for conscription, so that a recruiting party could be told where to go. Postal delivery is a later civilian benefit of a military register: a good example of infrastructure whose eventual use is entirely benign and entirely unlike its purpose.

James Scott's word for all of this is legibility: the arrangements that make a population countable and taxable from a distance. Fixed surnames, standard weights and measures, cadastral maps, land registers, street numbering and scientific forestry are all instances of the same move. Each replaces a workable local practice with a uniform one that can be read from a capital city.

His argument is not that legibility is malign, and this is the part most often lost. A state that cannot see its population cannot deliver a vaccine, a pension or a school place either, and the same instruments that enable conscription enable public health. What he objects to is the confidence that the simplification is costless. It always discards something (the local knowledge, the flexibility, the accommodations that made the previous arrangement work) and the loss shows up later, in a form nobody connects back to the decree.

The modern version of this is a digital identity scheme: one legal name, one address, one number, one record. The benefits are exactly the historical ones, and they are real. So is the cost, and it falls on precisely the same people it always did. Anybody with two households, no fixed address, a name spelled differently in two systems, a status that does not map onto the available field, or a life that does not resolve to a single row will have trouble, not because anybody intended it, but because that is what a uniform index does to everything that is not uniform.

The historical parallel is not decorative. It predicts, quite specifically, who will be left outside, and it has been predicting the same group for four hundred years.
