Most peoples, barbarians even, believed in some sort of a future state, in the principle of good and evil, and of rewards and punishments. There needs no argument then to account for the insatiable longing to pry into futurity, and to discover its hidden mysteries. The same idea unsettled the minds of former generations, nor can it be truthfully said to have disappeared before the vaunted wisdom of this utilitarian age. Like all forbidden fruit, this may be said to be the subject of greatest anxiety to weak human kind.
What then is this talisman with the aid of which we strive to penetrate the secrets of the world beyond us?
Man being what he is, only “a little lower than the angels,” endowed with the supernatural power of calling up at will mental images of both the living and the dead, of building air-castles, and peopling them according to his fantasy, as well in Cathay as in Spain, of standing by the side of an absent friend on the summit of Mont Blanc, one moment among the snows, the next flitting through the garden spots of sunny Italy--if he is thus capable of transporting himself into an enchanted land by the mere exercise of the power of his imagination--what could better serve him as a medium of communication with the unknown, and what shall deter him from seeking to fathom its deepest mysteries? Napoleon said truly that the imagination governs the universe. Every one has painted his own picture of heaven and hell as well as Dante or Milton, or the divine mysteries as truly as Leonardo or Murillo. Surely, the imagination could go no further.
Assuming this to be true, there is little need to ask why, in this enlightened age, the attempt should be made to revive vagaries already decrepit, that would much better be allowed to go out with the departed century, unhonored and unsung. Such a question could proceed only from a want of knowledge of the true facts in the case.
But whether superstition is justified by the dictates of a sound common sense, is not so material here, as whether it actually does exist; and if so, to what extent. That is what we shall try to make clear in the succeeding pages. The inquiry grows interesting in many ways, but most of all, we think, as showing the slow stages by which the human mind has enfranchised itself from a species of slavery, without its counterpart in any direction to which we may turn for help or guidance. Even science, that great leveller of popular error, limps here. Certainly, what has existed as long as human history must be accepted as a more or less active force in human affairs. We are not, therefore, dealing with futilities.
