From the foregoing observations we may venture to conclude, that an individual who gives credence to apparitions will also believe in the incarnation of the devil. In both cases we infer that spiritual beings can assume corporeal forms; and, although we may not presume to question the possibility of such appearances when it may please the Omnipotent so to will it, to believe in possession is actually to admit that the devil is a spiritual being endowed with specific attributes and powers, and acting either independently or with the consent of the Almighty. This admission would to a certain extent border on the heresy of the Manicheans, who believed, with the heresiarch Cubricus, that there existed a good and an evil principle coeternal and independent of each other. We find in Holy Writ that indulgence was granted to Satan to visit the earth. But the period when miraculous power ceased, or rather was withdrawn from the church, is not determined. The Protestants bring it down beneath the accession of Constantine, while the Roman Catholic clergy still claim the power of producing or procuring supernatural manifestations when it suits their purpose; but, as Scott justly observes, it is alike inconsistent with the common sense of either Protestant or Roman Catholic, that fiends should be permitted to work marvels, which are no longer exhibited on the part of religion. Cullen's opinion on this disease is worthy of remark. He says, "I do not allow that there is any true daemonomania, because few people nowadays believe that demons have any power over our bodies or our minds; and, in my opinion, the species recorded are either a species of melancholy or mania,--diseases falsely referred by the spectators to the power of demons,--feigned diseases,--or diseases partly real or partly feigned." Esquirol, moreover, justly observes, that "in modern times the punishments that the priest denounces have ceased to influence the minds and the conduct of men, and governments have recourse to restraints of a different kind. Many lunatics express now as much dread of the tribunals of justice, as they formerly entertained of the influence of stars and demons." We frequently meet with despondent monomaniacs labouring under the fatal delusion of having forfeited all hopes of salvation, and being in fact inevitably doomed to perdition, but who are apparently of sound mind when touching upon other subjects. The case of one Samuel Brown was peculiarly striking. This unfortunate man, at a period when all his intellectual faculties were in full vigour, fancied that his rational soul had gradually succumbed under divine displeasure, and that he solely enjoyed an animal life in common with brutes.
