Jonathan Gottschall has written an extremely interesting and captivating book in The Storytelling Animal: How Stories Make Us Human. I was surprised upon picking up this book how little that is not story in our lives: there are the expected books of course, but also tv, movies, jokes, commercials, lies, gathering 'round the water cooler, advertisements, songs, conspiracy theories and even sports events; really, the list goes on. Gottschall delves into the fascinating evolutionary, cultural, biological, and even neurological reasons why our species is defined by our storytelling, both communal and individual.
Did you know, for example, that according to one study "heavy fiction readers had better social skills--as measured by tests of social and empathic ability--than those who mainly read nonfiction"? (I'm curious to know if readers overall have the same relative abilities compared to non-readers...)
This is by far the most compelling non-narrative nonfiction I've read in simply ages, and what's more, it should be required reading for every single reader and writer out there.
