Degeneracy

CONSIDERED as a condition hurtful to the type, the conception of degeneracy may be said to appear even in the precursors of man, since animals destroy soon after birth offspring which, to them, appear peculiar. With that stage of development of the religious sense marked by assigning malign occult powers to natural objects and forces, this view of degeneracy became systematised, and exposed weakly or deformed offspring, charged to evil powers, to death. This occult conception of degeneracy is even yet a part of American folklore. Against degenerate children charms are still used by the "witch-doctors" among the "Pennsylvania Dutch." These people are on the level of culture of the early seventeenth century middle class English, if not a little below it. The folklore of these, as embodied in Shakespeare, demonstrates, according to J. G. Kiernan, that ere the seventeenth century the fact that "mental and moral defect expressed itself in physical stigmata was recognised and even the term used." Thistleton Dyer remarks that it is an old prejudice, not yet extinct, that those who are defective or deformed are marked by nature as prone to mischief.
