The knowledge of the past which automatic communications manifest is in most cases apparently referable to the actual memory of persons still existing beyond the tomb. It reaches us telepathically, as from a mind in which remote scenes are still imprinted. But there are certain scenes which are not easily assigned to the individual memory of any given spirit. And if it be possible for us to learn of present facts by telæsthesia as well as by telepathy;--by some direct supernormal percipience without the intervention of any other mind to which the facts are already known,--may there not be also a retrocognitive telæsthesia by which we may attain a direct knowledge of facts in the past? Some conception of this kind may possibly come nearest to the truth. It may even be that some World-Soul is perennially conscious of all its past; and that individual souls, as they enter into deeper consciousness, enter into something which is at once reminiscence and actuality. But nevertheless a narrower hypothesis will cover the actual cases with which we have to deal. Past facts are known to men on earth not from memory only, but by written record; and there may be records, of what kind we know not, which persist in the spiritual world. Our retrocognitions seem often a recovery of isolated fragments of thought and feeling, pebbles still hard and rounded amid the indecipherable sands over which the mighty waters are "rolling evermore." When we look from Time Past to Time Future we are confronted with essentially the same problems, though in a still more perplexing form, and with the world-old mystery of Free Will _versus_ Necessity looming in the background. Again we find that, just as individual memory would serve to explain a large proportion of Retrocognition, so individual forethought--a subliminal forethought, based often on profound organic facts not normally known to us--will explain a large proportion of Precognition. But here again we find also precognitions which transcend what seems explicable by the foresight of any mind such as we know; and we are tempted to dream of a World-Soul whose Future is as present to it as its Past. But in this speculation also, so vast and vague an explanation seems for the present beyond our needs; and it is safer--if aught be safe in this region which only actual evidence could have emboldened us to approach--to take refuge in the conception of intelligences not infinite, yet gifted with a foresight which strangely transcends our own.
