For the rest children’s shrinking from animals has much of the caprice of grown-up people’s. Not that there is anything really inexplicable in these odd directions of childish fear, any more than in the unpredictable shyings of the horse. If we knew the whole of the horse’s history, and could keep a perfect register of the fluctuations of ‘tone’ in his nervous system, we should understand all his shyings. So with the child. All the vagaries of his dislike to animals would be cleared up if we could look into the secret workings of his mind and measure the varying heights of his courage. That some of this early disquietude at the sight of strange animals is due to the workings of the mind is seen in the behaviour of Preyer’s boy when at the age of twenty-seven months he was taken to see some little pigs. The boy at the first sight looked earnest, and as soon as the lively little creatures began to suckle the mother he broke out into a fit of crying and turned away from the sight with all the signs of fear. It appeared afterwards that what terrified the child was the idea that the pigs were biting their mother; and this gave rise in the fourth and fifth years to recurrent nocturnal fears of the biting piglets, something like C.’s nocturnal fear of the wolf.[146] To an imaginative child strongly predisposed to fear, anything suggestive of harm will suffice to beget a measure of trepidation. A child does not want direct experience of the power of a big animal in order to feel a vague uneasiness when near it. His own early inductions respecting the correlation of bigness with strength, aided as this commonly is by information picked up from others, will amply suffice. In the case of the dog, the rough shaggy coat, the teeth which he is told can bite, the swift movements, and worse than all the appalling bark, are quite enough to disconcert a timid child. Even the sudden pouncing down of a sparrow may prove upsetting to a fearful mite as suggesting attack; and a girl of four may be quite capable of imagining the unpleasantness of an invasion of her dainty person by a small creeping wood-louse—which though running slowly was running towards herself—and so of getting a fit of shudders. ----- Footnote 146: See Preyer, _op. cit._, p. 130. -----
