“But this is not to say that a highly specialized body of belief such as that associated with Faerie is not capable of subsidiary explanations apart from this very general conclusion, specially in connection with those later and accretive ideas which must have grown up around it. Admittedly there is a common basis for the origin of all beliefs associated with the origin of spirits, which is to be found alone in the doctrine of animism. This notwithstanding, and with all due respect to the warnings of Krappe, Hartland, and others concerning the risks accruing to the scientific classification of spiritual forms, certain types of spirits with markedly separate characteristics have assuredly been conceived, and have been given diverse denominations and descriptions by those who believed in their existence. Of this the fairy type is indeed a case in point; and however correct it may be to say that it cannot basically be separated from the ghost, the goblin, or the demon, it has, in the course of ages, assumed characteristics which in a secondary sense distinguish it sufficiently from all of these to permit the scientific observer, and to some extent the peasant or the savage, to rank it as a separate variety of spirit, if not as a distinct species.”
