Another theory that seeks to drain all the pleasure out of reading

Literary Darwinism:

Just as Charles Darwin studied animals to discover the patterns behind their development, Literary Darwinists read books in search of innate patterns of human behavior: child bearing and rearing, efforts to acquire resources (money, property, influence) and competition and cooperation within families and communities. They say that it's impossible to fully appreciate and understand a literary text unless you keep in mind that humans behave in certain universal ways and do so because those behaviors are hard-wired into us. For them, the most effective and truest works of literature are those that reference or exemplify these basic facts.
