Escaping the Prison

I think Tolkien really hit it on the head with this quote about the importance of fairy tales.

“I have claimed that Escape is one of the main functions of fairy-stories, and since I do not disapprove of them, it is plain that I do not accept the tone of scorn or pity with which ‘Escape’ is now so often used. Why should a man be scorned if, finding himself in prison, he tries to get out and go home? Or if he cannot do so, he thinks and talks about other topics than jailers and prison-walls?”
–J.R.R. Tolkien
