Wistful Thinking

Robin Hanson wonders why fantasy novels and films often employ nostalgia:

Both magic and nostalgia rely especially heavily on wishful thinking – magic presumes we are especially able to influence events important to us, while nostalgia presumes that our previous social orders were especially functional, moral, good to people like us, etc. The fact that fantasy tends to combine both magic and nostalgia suggests that some readers have an especially strong tolerance for wishful thinking, and/or demand for comfort, and fantasy targets that audience.
