invisibility of phantoms has been obviously shaped with reference to actual experience. To declare that souls or ghosts are necessarily either visible or invisible, would directly contradict the evidence of men's senses. But to assert or imply, as the lower races do, that they are visible sometimes and to some persons, but not always or to every one, is to lay down an explanation of facts which is not indeed our usual modern explanation, but which is a perfectly rational and intelligible product of early science.
