Sách nói: Witchcraft of New England Explained by Modern Spiritualism

"It is not our purpose to write history, but to give new explanation of old events. The long and widely tolerated theory that New England witchcraft was exclusively but out-workings of mundane fraud, imposture, cunning, trickery, malice, and the like, has never adequately met the reasonable demand of common sense, which always asks that specified agents and forces shall be probably competent to produce all such effects as are distinctly ascribed to them."
