Still, the bad spelling and grammar of most of the letters up to that period, and the general ignorance of our upper classes were, says Professor Brewer, the reason why the whole government of the country was in the hands of ecclesiastics.

So wait, Ye Olde English being mostly incomprehensible gibberish is because the people writing it were basically functionally illiterate, ha ha?
Also~ This is why literacy is important. For example, slave owners really didn’t want their slaves to learn how to read. Catching them with any sort of letters was punishable with whipping. So there’s probably a correlation between illiteracy and being ruled by others. But as always, people can make their own conclusions.
Though, it’s important to note that there’s also an important distinction between knowing how to read and understanding what you read. Unfortunately, the latter seems to be an increasingly lost art.
