GENERAL INTRODUCTION Various possible plans have presented themselves for setting forth the living Fairy-Faith as I have found it during my travels in the six Celtic countries among the people who hold it. To take a bit here and a bit there from a miscellaneous group of psychological experiences, fairy legends and stories which are linked together almost inseparably in the mind of the one who tells them, does not seem at all satisfactory, nor even just, in trying to arrive at a correct result. Classification under various headings, such, for example, as Fairy Abductions, Changelings, or Appearances of Fairies, seems equally unsatisfactory; for as soon as the details of folk-lore such as I am presenting are isolated from one another--even though brought together in related groups--they must be rudely torn out of their true and natural environment, and divorced from the psychological atmosphere amidst which they were first presented by the narrator. The same objection applies to any plan of dividing the evidence into (1) that which is purely legendary; (2) that which is second-hand or third-hand evidence from people who claim to have seen fairies, or to have been in Fairyland or under fairy influences; and (3) that which is first-hand evidence from actual percipients: these three classes of evidence are so self-evident that every reader will be able to distinguish each class for himself as it occurs, and a mechanical classification by us is unnecessary. So no plan seems so good as the plan I have adopted of permitting all witnesses to give their own testimony in their own way and in its native setting, and then of classifying and weighing such testimony according to the methods of comparative religion and the anthropological sciences.
