Hello Kenneth, I like your question regarding links, books, quotes from Campbell on defining what is good or bad. You write, “For example I have a question for a documentary I am directing about the myths associated with the meaning of good and bad.”
I recall Campbell referring to good and bad in his discussions on duality, in the Power of Myth (Discussions with Bill Moyer). He says, we live in the world of opposites, “good or bad, night and day, black and white” ….and the talk develops on duality.
I’ll search that topic and write back. Sorry, I am so late in responding to this excellent question.
