I teach once every few weeks for an hour or two to a group of youngsters (ca. age ten). The lesson is provided to me, so it is pretty much cookbook, and is mostly about little activities and anecdotes, although certain sections are experiential or conversational. This next lesson seems especially applicable tomorrow. It begins with this quotation:
Nature has given [people] one tongue but two ears, that we may hear from others twice as much as we speak. — Epictetus, the Greek Stoic philosopher
I don't plan to lecture much tomorrow, but in order to better understand this lesson, I'd like to know more about what philosophical grounding this statement has, especially as told by Epictetus, about whom I know little.
My specific questions: Was this meant to be taken literally as a morphological justification? Is the proportion meant to be exact? Am I completely missing the point with questions like this?
