The annals of the Middle Ages furnish many cases similar to these of Grenier and Roulet. Their share in maintaining the werewolf superstition is undeniable; but modern science finds in them nothing that cannot be readily explained. That stupendous process of breeding, which we call civilization, has been for long ages strengthening those kindly social feelings by the possession of which we are chiefly distinguished from the brutes, leaving our primitive bestial impulses to die for want of exercise, or checking in every possible way their further expansion by legislative enactments. But this process, which is transforming us from savages into civilized men, is a very slow one; and now and then there occur cases of what physiologists call atavism, or reversion to an ancestral type of character. Now and then persons are born, in civilized countries, whose intellectual powers are on a level with those of the most degraded Australian savage, and these we call idiots. And now and then persons are born possessed of the bestial appetites and cravings of primitive man, his fiendish cruelty and his liking for human flesh. Modern physiology knows how to classify and explain these abnormal cases, but to the unscientific mediaeval mind they were explicable only on the hypothesis of a diabolical metamorphosis. And there is nothing strange in the fact that, in an age when the prevailing habits of thought rendered the transformation of men into beasts an easily admissible notion, these monsters of cruelty and depraved appetite should have been regarded as capable of taking on bestial forms. Nor is it strange that the hallucination under which these unfortunate wretches laboured should have taken such a shape as to account to their feeble intelligence for the existence of the appetites which they were conscious of not sharing with their neighbours and contemporaries. If a myth is a piece of unscientific philosophizing, it must sometimes be applied to the explanation of obscure psychological as well as of physical phenomena. Where the modern calmly taps his forehead and says, "Arrested development," the terrified ancient made the sign of the cross and cried, "Werewolf."We shall be assisted in this explanation by turning aside for a moment to examine the wild superstitions about "changelings," which contributed, along with so many others, to make the lives of our ancestors anxious and miserable.
These superstitions were for the most part attempts to explain the phenomena of insanity, epilepsy, and other obscure nervous diseases. A man who has hitherto enjoyed perfect health, and whose actions have been consistent and rational, suddenly loses all self-control and seems actuated by a will foreign to himself. Modern science possesses the key to this phenomenon;but in former times it was explicable only on the hypothesis that a demon had entered the body of the lunatic, or else that the fairies had stolen the real man and substituted for him a diabolical phantom exactly like him in stature and features.
Hence the numerous legends of changelings, some of which are very curious. In Irish folk-lore we find the story of one Rickard, surnamed the Rake, from his worthless character. Agood-natured, idle fellow, he spent all his evenings in dancing,--an accomplishment in which no one in the village could rival him. One night, in the midst of a lively reel, he fell down in a fit. "He's struck with a fairy-dart,"exclaimed all the friends, and they carried him home and nursed him; but his face grew so thin and his manner so morose that by and by all began to suspect that the true Rickard was gone and a changeling put in his place. Rickard, with all his accomplishments, was no musician; and so, in order to put the matter to a crucial test, a bagpipe was left in the room by the side of his bed. The trick succeeded. One hot summer's day, when all were supposed to be in the field ****** hay, some members of the family secreted in a clothes-press saw the bedroom door open a little way, and a lean, foxy face, with a pair of deep-sunken eyes, peer anxiously about the premises.
Having satisfied itself that the coast was clear, the face withdrew, the door was closed, and presently such ravishing strains of music were heard as never proceeded from a bagpipe before or since that day. Soon was heard the rustle of innumerable fairies, come to dance to the changeling's music.
Then the "fairy-man" of the village, who was keeping watch with the family, heated a pair of tongs red-hot, and with deafening shouts all burst at once into the sick-chamber. The music had ceased and the room was empty, but in at the window glared a fiendish face, with such fearful looks of hatred, that for a moment all stood motionless with terror. But when the fairy-man, recovering himself, advanced with the hot tongs to pinch its nose, it vanished with an unearthly yell, and there on the bed was Rickard, safe and sound, and cured of his epilepsy.[81]

Comparing this legend with numerous others relating to changelings, and stripping off the fantastic garb of fairy-lore with which popular imagination has invested them, it seems impossible to doubt that they have arisen from myths devised for the purpose of explaining the obscure phenomena of mental disease. If this be so, they afford an excellent collateral illustration of the belief in werewolves. The same mental habits which led men to regard the insane or epileptic person as a changeling, and which allowed them to explain catalepsy as the temporary departure of a witch's soul from its body, would enable them to attribute a wolf's nature to the maniac or idiot with cannibal appetites. And when the myth-forming process had got thus far, it would not stop short of assigning to the unfortunate wretch a tangible lupine body;for all ancient mythology teemed with precedents for such a transformation.
