Most people, when they hear Aesop's name, think "talking animals." That, however, is not the complete picture. Many of Aesop's short stories feature people, and several of the Greek gods and heroes also make an appearance. They address a wide variety of morals and teachings, sometimes longer than the story itself.
I just run into this particular Aesop's fable today, and I thought I'd share, since it is very applicable to modern day situations:
"Oh Heracles, don't be surprised! That object you have been trying to smash so heroically is Strife itself. The more one tries to destroy it by force, the larger it gets. If you leave it alone, it stays small; but if you try to fight it, it will become a rather large inconvenience."
"So... it wasn't an apple, then?"
"No, Heracles, it wasn't an apple."
"Oh good. That would have been embarrassing."
Okay, so I might have embellished it a little, but the gist is the same. I wanted to share it as an illustration to the idea that "not feeding the trolls" is by no way a modern concept that came about with the age of the Internet. People have been perfectly well arguing endlessly about insignificant things long before technology made the option global.
I also find it fun that Strife resembles an apple; it is probably a nod to Eris' golden apple that stared that whole mess with Helen of Troy.
