"There have been men (thou mayst have known such), who, after an illness in which life itself seemed suspended, have arisen, as out of a sleep, with characters wholly changed. Before, perhaps, gentle and good and truthful, they now become bitter, malignant, and false. To the persons and the things they had before loved, they evince repugnance and loathing. Sometimes this change is so marked and irrational that their kindred ascribe it to madness,--not the madness which affects them in the ordinary business of life, but that which turns into harshness and discord the moral harmony that results from natures whole and complete. But there are dervishes who hold that in that illness, which had for its time the likeness of death, the soul itself has passed away, and an evil genius has fixed itself into the body and the brain, thus left void of their former tenant, and animates them in the unaccountable change from the past to the present existence. Such mysteries have formed no part of my study, and I tell you the conjecture received in the East without hazarding a comment whether of incredulity or belief. But if, in this war between the mind which the fiends have seized, and the soul which implores refuge of Allah; if, while the mind of yon traveller now covets life lengthened on earth for the enjoyments it had perverted its faculties to seek and to find in sin, and covets so eagerly that it would shrink from no crime and revolt from no fiend that could promise the gift, the soul shudderingly implores to be saved from new guilt, and would rather abide by the judgment of Allah on the sins that have darkened it than pass forever irredeemably away to the demons,--if this be so, what if the soul's petition be heard; what if it rise from the ruins around it; what if the ruins be left to the witchcraft that seeks to rebuild them? There, if demons might enter, that which they sought as their prize has escaped them; that which they find would mock them by its own incompleteness even in evil. In vain might animal life the most perfect be given to the machine of the flesh; in vain might the mind, freed from the check of the soul, be left to roam at will through a brain stored with memories of knowledge and skilled in the command of its faculties; in vain, in addition to all that body and brain bestow on the normal condition of man, might unhallowed reminiscences gather all the arts and the charms of the sorcery by which the fiends tempted the soul, before it fled, through the passions of flesh and the cravings of mind: the Thing, thus devoid of a soul, would be an instrument of evil, doubtless,--but an instrument that of itself could not design, invent, and complete. The demons themselves could have no permanent hold on the perishable materials. They might enter it for some gloomy end which Allah permits in his inscrutable wisdom; but they could leave it no trace when they pass from it, because there is no conscience where soul is wanting.
