A friend once asked me why it was that stories about animals and their heroism...are so compelling.
...we love them because they're the closest thing we have to material evidence of an objective moral order--or, to put it another way, they're the closest thing we have to proof of the existence of God. They seem to prove that the things that matter to and move us the most--things like love, courage, loyalty, altruism--aren't just ideas we made up from nothing. To see them demonstrated in other animals proves they're real things, that they exist in the world independently of what humans invent and tell each other in the form of myth or fable.
