Something that bugs the hell out of me, literally, is the misuse of English. Of course, I was trained as a subeditor in the days when such things mattered even to journalists, so I am a fossilised dinosaur in this respect. I even try to use adverbs correctly. One thing that literally makes my head explode, is the misuse by academics of the phrase “begs the question” to mean “raises a question”.
“Begging the question” is a colloquial translation of the Latin phrase petitio principii, which means to petition the premise of an argument in your conclusion. Whately defines it thus: [it] “takes place when one of the Premisses (whether true or false) is either plainly equivalent to the conclusion, or depends upon that for its own reception.” This is also called “circular reasoning” or “arguing in a vicious circle”.
However, even among the cognoscenti, it has come to mean “raises a question in a context”. For example, I hear commentators say that a particular fact “begs the question why”… and I give an involuntary shudder every time.
Linguistic usage, however, trumps rules of style. Unfortunately, how people use a language determines the meaning of a term or phrase, and if all but a few use it this way, then it has come to mean that. During the transition from the older use to the newer, curmudgeons like me can assert that the new use is an error, but once the tide has washed in, too late. Descriptivism overrules prescriptivism.
But now we need a phrase for the older meaning. It is a basic logical error, and “vicious circle” doesn’t quite capture the mistake. I would suggest that a lot of the work of the older phrase was done by the term “beg”, and that is what changed its overall connotations, leading to the drift in meaning of the phrase. So what is it to “beg” a question? It is to help yourself to something that is not earned (the premise in question). How about we go a little more forcefully, and call it “stealing” the question (like stealing a base in American baseball)? You don’t get there by hitting a ball but by sneaky activity in the background.
Henceforth, all you cognoscenti must call this “stealing the question”, and allow all those logical illiterates to continue to call raising a question “begging the question”. And we purists will continue to vomit a little each time.
