Of course! Fairy tales for children are how we communicate some of our best understandings of what it means to live a good life.

Many important things in life are fictions or rely on fictions - money, nations, property, family, art, justice, legitimacy, banks. All of them are fairytales. And like a fairy in Peter Pan, belief can make them real, powerful facts of our world while lack of belief can destroy them.

It works too - I know lots of real people who make the world a better place because of the fairy tales they choose to believe.
