Since the 70s, morals to a story have been specifically not permitted in most paid writing. Why not? Since we now know that academic success is predicted foremost by character training, we need to reverse this.
On second thought, all stories have moral points. So what we need to do is to articulate, specifically, the good moral points. Further, we might reflect upon moral points that are bad. And then disallow them. We really don’t need stories like that, do we?
I recommend the books of Advance Publishing, by Carl Sommer. All of these books were written to be used in elementary public schools, so many may be useful to my CDC clients. I do have some of these one hand, for my Austin clients.
