It is by the hypothesis of this universal sense, latent within us—an hypothesis which, whoever believes that we are immortal spirits, incorporated for a season in a material body, can scarcely reject—that I seek to explain those perceptions which are not comprised within the functions of our bodily organs. It seems to me to be the key to all or nearly all of them, as far as our own part in the phenomena extends. But, supposing this admitted, there would then remain the difficulty of accounting for the partial and capricious glimpses we get of it; while in that department of the mystery which regards apparitions, except such as are the pure result of disease, we must grope our way, with very little light to guide us, as to the conditions and motives which might possibly bring them into any immediate relation with us. To any one who has been fortunate enough to witness one genuine case of clairvoyance, I think the conception of this universal sense will not be difficult, however the mode of its exercise may remain utterly incomprehensible. As I have said above—to the great Spirit and Fountain of life, all things, in both space and time, must be present. However impossible it is to our finite minds to conceive this, we must believe it. It may, in some slight degree, facilitate the conception to remember that action, once begun, never ceases—an impulse given is transmitted on for ever; a sound breathed reverberates in eternity; and thus the past is always present, although, for the purpose of fitting us for this mortal life, our ordinary senses are so constituted as to be unperceptive of these phenomena. With respect to what we call _the future_, it is more difficult still for us to conceive it as present; nor, as far as I know, can we borrow from the sciences the same assistance as mechanical discoveries have just furnished me with in regard to the past. How a spirit sees that which has not yet, to our senses, taken place, seems certainly inexplicable. _Foreseeing_ it is not inexplicable: we foresee many things by arguing on given premises, although, from our own finite views, we are always liable to be mistaken. Louis Lambert says: “Such events as are the product of humanity, and the result of its intelligence, have their own causes, in which they lie latent, just as our actions are accomplished in our thoughts previous to any outward demonstration of them; presentiments and prophecies consist in the intuitive perception of these causes.” This explanation, which is quite conformable with that of Cicero, may aid us in some degree as regards a certain small class of phenomena; but there is something involved in the question much more subtle than this. Our dreams can give us the only idea of it; for there we do actually see and hear, not only that which never was, but that which never will be. Actions and events, words and sounds, persons and places, are as clearly and vividly present to us as if they were actually what they seem; and I
