Poul Anderson's "Star of the Sea" is about the growth of myths as meaningful stories, not as mere falsehoods. I think that somewhere in this story Everard remembers Stalin asking derisively how many divisions the Pope commands, not realizing that people live by myths.
"We need myths, [Juniper] thought. We live by them. But can we live in them?"
-SM Stirling, Dies The Fire (New York, 2005), p. 508.
Populations for generations have lived inside myths, never questioning their received doctrines about supernatural beings and a hereafter. I am glad to live in a period when we can compare traditions and question inherited indoctrinations.
