"The motive power of the moral life is Will. The motive power of the intellectual world is Imagination. In virtue of his power to imagine or re-create through mental images, man sees the past, forecasts the future, and has made whatever advances has been ever made into the fields of the Unknown.
"We cannot give Imagination to another, but we may arrest its development; and where it is ignored or suppressed, all intellectual life must quickly decline and perish. Now, as of old, wherever for one reason or another there is no vision the people perish."
Fairy tales are a prime tool and so vital in nurturing the Imagination! Don't underestimate their power and usefulness.
