Josef Baudiš, Folk-Lore (1916)
“ This belief is based on primitive conceptions of life. To primitive man there is no difference between an animal and a human being; their external form is only a casual accident: "the bear whom the savage meets in the woods is too cunning to appear and to battle with him as a man, but he could if he chose" (Hartland, The Science of Fairy Tales, 26) . Our motive is only a logical consequence of this ancient savage belief: if shape-shifting is possible, why cannot two human beings also exchange their shape one with another? ”
