And the second thing fiction does is to build empathy. When you watch TV or see a film, you are looking at things happening to other people. Prose fiction is something you build up from 26 letters and a handful of punctuation marks, and you, and you alone, using your imagination, create a world and people it and look out through other eyes. You get to feel things, visit places and worlds you would never otherwise know. You learn that everyone else out there is a me, as well. You're being someone else, and when you return to your own world, you're going to be slightly changed. Empathy is a tool for building people into groups, for allowing us to function as more than self-obsessed individuals.
