Francis John Shepherd, Popular Science Monthly (1883)
“ Southey says: "Man is a dupable animal; quacks in medicine, quacks in religion, and quacks in politics know this, and act upon that knowledge. There is scarcely any one who may not, like a trout, be taken by tickling." It is extraordinary what a hold the mystic and marvelous still have on many people; there seems to be in almost every one a vein of credulity and superstition against which argument is useless. The disposition to be humbugged preponderates in human nature over reason and common sense. ”
