Examination of the basement walls--the foundations--of prevalent popular explanation of ancient wonders, forces conviction that they lack both the breadth and the materials needful to stability. Modern builders of witchcraft history have either failed to find, or have deemed unmanageable by any appliances at their command, and therefore would not attempt to handle, a vast amount of sound historic stones which are accessible and can be used. Lacking them, these moderns have let fancy manufacture for them, and they have builded upon blocks of her fragile stuff which are fast disintegrating under the chemical action of the world's common sense. We proposed here an incipient step towards refutation of the sufficiency and justness of a main theory, now long prevalent, for explaining satisfactorily very many well-proved marvelous facts. Some such have been presented on the pages of Hutchinson, Upham, and their followers; and yet these have been either not at all, or vaguely or ludicrously, commented upon, or reasoned from. Very many others, and the most important of all as bases and aids to an acceptable and true solution of the whole, are not visible where they ought to have conspicuous position. Presentation and proper use of them might have caused public cognizance to topple over the edifices which it has pleased modern builders to erect. 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.
