Nobody said that literally was never used in literature. In fact, the fact that literally has been used in place of figuratively for hundreds of years appears right at the beginning of this thread.
What people are complaining about is your constant critique of so-called bad writers who use literally without a literary aspect, those who literally use such phrases as “my head literally exploded” in any formal situation. That is the claim you cannot support.
While we’re at it, I should also ask why someone who claims to revere language doesn’t understand that dictionaries run years behind contemporary usage. What the literal fuck? One of the last things they bother to update is changes in subsidiary meanings. Few have the resources to do continual updates.
Oh, you might have noticed the phrase “what the literal fuck”? I didn’t invent the phrase. It has an UrbanDictionary entry, although it is not as common a term as “what the actual fuck”. Professional linguists note that such phrases fail to conform to standard parsings of grammar, but are used every day in casual speech and on social media. Can we just ignore the part they play in social discourse because some people consider them vulgar and would bar them from formal writing?
If you can’t guess, my answer is no. What the fuck, abbreviated WTF, has entered the educated vocabulary. You may deplore such usage but the term is useful in multiple situations and so is used by all levels of speakers. Such terms are subject to intensification, a process so basic to and standard in English that many unobjectionable everyday terms contain hidden intensifiers. (see Deutscher above) No one, no authority, no Grammar Nazi or language puritan, can stem the flow of that process. It’s innate to expression of tone, meaning, and urgency, the core of intercourse in the oldest sense. What the literal/actual fuck is intensification in exactly that sense.
An expression of surprise or confusion used when what the fuck is insufficient to convey the magnitude of the situation. The increasingly flippant use and associated devaluation of the query ‘what the fuck?’ has necessitated the creation a more heart-felt derivative.
Holy fucking shit! UrbanDictionary[!] understands the vital need for intensification and can identify the steps of the process in formal terms. You can howl from now to forever about how this devaluation degrades the language and removes the precious exactitude of terms that writers employ to create the sense of nuanced clarity that is the mark of great writing. Probably less than 1% of language is ever designed to be read in this way. The other 99% is rightly more much concerned with simple communication from one person to another.
William F. Buckley, who was good with words, once wrote: "A conservative is someone who stands athwart history, yelling Stop, at a time when no one is inclined to do so, or to have much patience with those who so urge it.” William F. Buckley was literally insane.
