In other words, to traditionalist folklorists, the "folk" were best understood as "illiterate, rural, backwards peasants" (Dundes 1980, 6), who, isolated from modern culture, retained "rural, quaint, or 'backward' elements of the culture" (Toelken 1979, 5). Underpinning this condescension was the theory of "cultural evolution," a late 19th-century adaptation of the then cutting-edge theory of Darwinian evolution to fields that had nothing to do with biology. This theory, whose primary exponents were E. B. Tylor and Andrew Lang, posited that cultures, just like individual humans, proceeded in a unilinear fashion through the stages of "savagery" (infancy), "barbarism" (childhood), and finally "civilization"—with upper-class European patriarchal Christian culture representing the pinnacle of civilization (and adulthood), of course. European peasants were, naturally, barbarians, and their folklore represented traces of earlier "stages" of civilization; information on the ancestors of civilized peoples could be supplemented with studies of contemporary "savages," such as African tribespeople (Dundes 1980, 2). Lang, in particular, argued that the child is the microcosm of the culture, and therefore, logically, the stories of lower-class "barbaric" adults were suitable material—after extensive bowdlerization—for upper-class children, as they were all on the same level of development (see Smol 1996). In other words, the still-pervasive notion that folktales, especially fairy tales, are primarily "kids' stuff" owes a great deal to 19th-century racism, classism, and religious bigotry.
