Fables were part of the moral fabric when I was growing up. Perhaps yours as well. Especially some of Aesop’s Fables. (Yet, I was suprised that this was not the case for many of my middle school students, when a public school teacher.)

There’s one fable, in particular, which social psychologist Jonathan Haidt discussed in a 2012 interview (noted below) about his latest book (at that time): Aesop’s The Ant and the Grasshopper.
