I do not believe that fear of the dark is universal among young children. I know a child that did not show any trace of it till some rather too gruesome stories of Grimm set his brain horror-spinning when he ought to have been going to sleep. A lady whom I know tells me that she never had the fear as a child though she acquired it later, towards the age of thirty. How common it is among children under ten or twelve, we have as yet no means of judging. Some inquiries of Dr. Stanley Hall show that out of about 300 young people under thirty only two appear to have been wholly exempt from it, but the ages at which the fear first appeared are not given.

Here, again, we have a counterbalancing side. An imaginative child can fill the dark vacancy of the bedroom with bright pleasing images. On going to bed and saying good-night to the world of daylight, he can see his beloved fairies, talk to them and hear them talk. We know how R. L. Stevenson must, when a child, have gladdened many of his solitary dark hours by bright fancies. Even when there is a little trepidation a hardy child may manage to play with his fears, and so in a sense to enjoy his black phantasmagoria, just as grown-ups may enjoy the horrors of fiction.

It will perhaps turn out that imaginative children have both suffered and enjoyed the most in these ways, the effect varying with nervous tone and mental condition. Yet it seems probable that the fearful suffering mood has here been uppermost.

Why these nocturnal images tend to be gloomy and alarming may, I think, be explained by a number of circumstances. The absence of light and the oncoming of night have, as we know, a lowering effect on the functions of the body; and it is not unlikely that this might so modify the action of the brain as to favour the rise of gloomy thoughts. The very blackness of night, too, which we must remember is actually seen by the child, would probably tend to darken the young thoughts. We know how commonly we make black and dark shades of colour symbols of melancholy and sorrow. If to this we add that in the night a child is apt to feel lost through a loss of all his customary landmarks, and that, worst of all, he is, in the midst of this blackness which blots out his daily home, left to himself, robbed of that human companionship which is his necessary stay and comfort, we need not, I think, wonder at his so often encountering "the terror by night".

(b) Damage of the Onslaught.

I have now, perhaps, illustrated sufficiently some of the more common and characteristic fears of children. The facts seem to show that they are exposed on different sides to the attacks of fear, and that the attacking force is large and consists of a variety of alarming shapes.

If now we glance back at these several childish fears, one feature in them which at once arrests our attention is the small part which remembered experiences of evil play in their production. The child is inexperienced, and if humanely treated knows little of the acuter forms of human suffering. It would seem at least as if he feared not so much because his experience had made him aware of a real danger in this and that direction, as because he was constitutionally and instinctively nervous, and possessed with a feeling of insecurity. More particularly children are apt to feel uneasy when face to face with the new, the strange, the unknown, and this uneasiness grows into a more definite feeling of fear as soon as the least suggestion of harmfulness is added; as when a child recoils with dread from a stranger who has a big projecting eye that looks a menace, or a squint which suggests a sly way of looking at you, or an ugly and advancing tooth that threatens to bite. How much the fear of the dark is due to inability to see and so to know is shown by the familiar fact that children and adults who can enter a strange gloomy-looking room and keep brave as long as things are before their eyes are wont to feel a creepy sense of "something" behind them when they turn their backs to retire and can no longer see. It is shown too in the common practice of children and their elders to look into the cupboard, under the bed, and so forth, before putting out the light; for that which has not been inspected retains dire possibilities of danger.

Where a child does not know he is apt to fancy something. It is the activity of children's imagination which creates and sustains the larger number of their fears. Do we not indeed in saying that they are for the greater part groundless say also that they are "fanciful"?

Children's fears are often compared with those of animals. No doubt there are points of contact. The misery of a dog when street music is going on is very suggestive of a state of uneasiness if not of fully developed fear. Dogs, cats, and other animals will "shy" at the sight of "uncanny" moving objects, such as leaves, feathers, and shadows. Yet the great point of difference remains that animals not having imagination are exempt from many of the fearful foes which menace childhood, including that arch-foe, the black night.

A much more instructive comparison of children's fears may be made with those of savages. Both have a like feeling of insecurity in presence of the big unknown, especially the mysterious mighty things, such as the storm-wind, and the rare and startling things, e.g., the eclipse and the thunder. The ignorance and simplicity of mind, moreover, aided by a fertile fancy, which lead to this and that form of childish fear are at work also in the case of uncivilised adults. Hence the familiar observation that children's superstitious fears often reflect those of savage tribes.
