By some official oversight, which I am quite unable to explain, we are still allowed to write private letters if we put them in public pillar-boxes. The Postmaster-General does not write all our letters for us; even the local postman has as yet no such local powers. I cannot conceive how it is that reformers have failed to note the need for uniting, reorganizing, coordinating, codifying, and linking up all this complex, chaotic, and wasteful system, or lack of system. There must be vast amounts of overlapping, with some six young gentlemen writing letters to one young lady. There must be a terribly low educational standard, with all sorts of poor people allowed to put into a private letter any spelling or grammar they like. There must be a number of bad psychological habits being formed, by foolish people writing their sons in the Colonies or their mothers in the workhouse. And all this anarchy and deterioration could be stopped by the simple process of standardisation of all correspondence.
G. K. Chesterton, Government and the Rights of Man. The rest of the essay is very much worth reading.
