In truth, the evidence with respect to such apparitions is very seldom accurately or distinctly questioned. A supernatural tale is in most cases received as an agreeable mode of amusing society, and he would be rather accounted a sturdy moralist than an entertaining companion who should employ himself in assailing its credibility. It would indeed be a solecism in manners, something like that of impeaching the genuine value of the antiquities exhibited by a good-natured collector for the gratification of his guests. This difficulty will appear greater should a company have the rare good fortune to meet the person who himself witnessed the wonders which he tells; a well-bred or prudent man will, under such circumstances, abstain from using the rules of cross-examination practised in a court of justice; and if in any case he presumes to do so, he is in danger of receiving answers, even from the most candid and honourable persons, which are rather fitted to support the credit of the story which they stand committed to maintain, than to the pure service of unadorned truth. The narrator is asked, for example, some unimportant question with respect to the apparition; he answers it on the hasty suggestion of his own imagination, tinged as it is with belief of the general fact, and by doing so often gives a feature of minute evidence which was before wanting, and this with perfect unconsciousness on his own part. It is a rare occurrence, indeed, to find an opportunity of dealing with an actual ghost-seer; such instances, however, I have certainly myself met with, and that in the case of able, wise, candid, and resolute persons, of whose veracity I had every reason to be confident. But in such instances shades of mental aberration have afterwards occurred, which sufficiently accounted for the supposed apparitions, and will incline me always to feel alarmed in behalf of the continued health of a friend who should conceive himself to have witnessed such a visitation.
The nearest approximation which can be generally made to exact evidence in this case, is the word of some individual who has had the story, it may be, from the person to whom it has happened, but most likely from his family, or some friend of the family. Far more commonly the narrator possesses no better means of knowledge than that of dwelling in the country where the thing happened, or being well acquainted with the outside of the mansion in the inside of which the ghost appeared.
