If, therefore, we hold by this new and fruitful method of social psychology we must be prepared to treat the Fairy-Faith of the Celtic peoples also in and for itself, as expressive of an individuality more or less unique. It might, indeed, be objected that these peoples are not a single social group, but rather a number of such groups, and this is, in a way, true. Nevertheless their folk-lore displays such remarkable homogeneity, from whatever quarter of the Celtic world it be derived, that it seems the soundest method to treat them as one people for all the purposes of the student of sociology, mythology, and religion. Granting, then, such a unity in the beliefs of the pan-Celtic race, we are finally obliged to distinguish as it were two aspects thereof.
On the one hand there is shown, even in the mere handful of non-Celtic parallels, which for reasons of space we have been content to cite, as well as in their Celtic equivalents, a generic element common to all peoples living under primitive conditions of society. It is emphatically a social element, but at the same time one which any primitive society is bound to display. On the other hand, in a second aspect, the Celtic beliefs show of themselves a character which is wholly Celtic: in the Fairy-Faith, which is generically animistic, we find reflected all sorts of specific characteristics of the Celtic peoples--their patriotism, their peculiar type of imagination, their costumes, amusements, household life, and social and religious customs generally. With this fact in mind, we may proceed to examine certain of the more specialized aspects of the Fairy-Faith, as manifested both among Celts and elsewhere.
THE SMALLNESS OF ELVISH SPIRITS AND FAIRIES
In any anthropological estimate of the Fairy-Faith, the pygmy stature so commonly attributed to various orders of Celtic and of non-Celtic fairies should be considered. Various scholarly champions of the Pygmy Theory have attempted to explain this smallness of fairies by means of the hypothesis that the belief in such fairies is due _wholly_ to a folk-memory of small-statured pre-Celtic races;[125] and they add that these races, having dwelt in caverns like the prehistoric Cave Men, and in underground houses like those of Lapps or Eskimos, gave rise to the belief in a fairy world existing in caverns and under hills or mountains. When analysed, our evidence shows that in the majority of cases witnesses have regarded fairies either as non-human nature-spirits or else as spirits of the dead; that in a comparatively limited number of cases they have regarded them as the souls of prehistoric races; and that occasionally they have regarded the belief in them as due to a folk-memory of such races. It follows, then, from such an analysis of evidence, that the Pygmy Theory probably does explain some ethnological elements which have come to be almost inseparably interwoven with the essentially animistic fabric of the primitive Fairy-Faith. But though the theory may so account for such ethnological elements, it disregards the animism that has made such interweaving possible; and, on the whole, we are inclined to accept Mr. Jenner's view of the theory (see p. 169). Since the Pygmy Theory thus fails entirely to provide a basis for what is by far the most important part of the Fairy-Faith, a more adequate theory is required.
