This one is mostly quoting G.K. Chesterton, and it's good stuff:
It has no more claim to be good literature than the daily conversation of its readers to be fine oratory, or the lodging-houses and tenements they inhabit to be sublime architecture. But people must have conversation, they must have houses, and they must have stories. The simple need for some kind of ideal world in which fictitious persons play an unhampered part is infinitely deeper and older than the rules of good art, and much more important.
