This is a interesting portray of the debate between Tolkien and Lewis whether or not myths are lies. It’s interesting how Tolkien argued (lesson for all of us when we say for instance that Balrogs have [or not] wings). Anyway, through this conversation, ultimately Lewis who was previously an atheist converted to Christendom.
