The passage's simple scale would be...
Psychologists such as Bettelheim:
those thinks fairy tales is used to give children lessons
and also they see children as evil and adults are non-selfish (take the second way of interpreting a story which the author gives (the other is what the author called superficial))
vs
Author&literature
It's not true that Children are selfish and adults are innocent...disagree with them
I'm not sure what the author means in the last sentence...this confused me because it seems the author agrees with Bettelheim because s/he says "hence the idea that a literature targeted for them must stand in the service of pragmatic instrumentality rather than foster an unproductive form of playful pleasure."
I thought the sentence started with the reason that leads psychologists (such as Bettelheim) to think about fairy tales, so it talks about pychologists...and thought it ends with the author's disagreement but it seems it ends with the author' agreement, s/he also thinks fairy tales should be something that teach children lessons...? (bc he uses must)
I thought the last paragraph is for rebutting the idea psychologists have but it is confusing...could anyone clarify it?
Thank you
