"One value in fairy stories for the young is that they embody and commemorate the man-child's first rude assertion of the lordship of mind, and subserve the development of a later sense of spiritual freedom and autonomy. Another is that they are expressive, as all art is expressive, of the idealistic hunger at the heart of men. Again, as forms of art, they select and co-ordinate those facts which bring out the spiritual meanings of life. That is, they release from the unsifted materials of experience the imprisoned 'Soul of Fact.' And not only do they embody the basic moral insights and interpretations of childish man, but they express the simple and larger emotions, and so feed the heart of the child. They quicken, too, the imagination--that master-faculty without which the sympathy which is man's highest and richest endowment fails of fruition. They are an aid to culture by giving an outlook upon all nations and kindreds, all countries and conditions of life. Finally, along with their allied forms of literary invention, the myth, saga, fable, and so on, they are a condition to understanding the innumerable allusions with which the literature of the world is studded."[15] All this is assuredly the function of the fairy tale, but frequently it is frustrated by the kind of fairy tales children are allowed to read. For one thing, the imaginative faculty is scarcely stimulated in a healthy fashion when the mind is led to dwell constantly, as in the case of Doctor Brill's patient, on thoughts of cruelty and pain. Nor can the fairy tale be said to have exerted a healthy influence in such a case as that represented by a little girl who was brought for treatment to another medical psychologist, and whose morbid irritability, disobedience, and crying spells were, by psychological analysis, traced to an excessive jealousy of her brother. In the course of the analysis the discovery was made that the girl had frequent dreams of seeing both her mother and her brother cruelly treated. In one dream, witches shut her mother in a cave to starve to death, and threw her brother into a large caldron of boiling water, leaving her to perish miserably. "This dream," the little girl naïvely explained to the physician who was analysing her mental states, "is just like the fairy tales I read." Other dreams of cruelty were likewise found to be drawn from the reading of unpleasant fairy tales. So that, although in this case jealousy was undoubtedly the chief cause of the nervous condition for which treatment was required, fairy tales also played a part in directing the course of the little girl's morbid thinking and her difficult behaviour. Warned by this revelation of the dream-analysis, her physician made it a point to notify her mother that unless steps were taken to change the girl's reading matter she might develop traits of character--harshness, coldness, indifference to the sufferings of others--that would handicap her throughout life.
