The general, or, it may be termed, the universal belief of the inhabitants of the earth, in the existence of spirits separated from the encumbrance and incapacities of the body, is grounded on the consciousness of the divinity that speaks in our bosoms, and demonstrates to all men, except the few who are hardened to the celestial voice, that there is within us a portion of the divine substance, which is not subject to the law of death and dissolution, but which, when the body is no longer fit for its abode, shall seek its own place, as a sentinel dismissed from his post. Unaided by revelation, it cannot be hoped that mere earthly reason should be able to form any rational or precise conjecture concerning the destination of the soul when parted from the body; but the conviction that such an indestructible essence exists, the belief expressed by the poet in a different sense, Non omnis moriar must infer the existence of many millions of spirits who have not been annihilated, though they have become invisible to mortals who still see, hear, and perceive, only by means of the imperfect organs of humanity. Probability may lead some of the most reflecting to anticipate a state of future rewards and punishments; as those experienced in the education of the deaf and dumb find that their pupils, even while cut off from all instruction by ordinary means, have been able to form, out of their own unassisted conjectures, some ideas of the existence of a Deity, and of the distinction between the soul and body—a circumstance which proves how naturally these truths arise in the human mind. The principle that they do so arise, being taught or communicated, leads to further conclusions.
These spirits, in a state of separate existence, being admitted to exist, are not, it may be supposed, indifferent to the affairs of mortality, perhaps not incapable of influencing them. It is true that, in a more advanced state of society, the philosopher may challenge the possibility of a separate appearance of a disembodied spirit, unless in the case of a direct miracle, to which, being a suspension of the laws of nature, directly wrought by the Maker of these laws, for some express purpose, no bound or restraint can possibly be assigned. But under this necessary limitation and exception, philosophers might plausibly argue that, when the soul is divorced from the body, it loses all those qualities which made it, when clothed with a mortal shape, obvious to the organs of its fellow-men. The abstract idea of a spirit certainly implies that it has neither substance, form, shape, voice, or anything which can render its presence visible or sensible to human faculties. But these sceptic doubts of philosophers on the possibility of the appearance of such separated spirits, do not arise till a certain degree of information has dawned upon a country, and even then only reach a very small proportion of reflecting and better-informed members of society. To the multitude, the indubitable fact, that so many millions of spirits exist around and even amongst us, seems sufficient to support the belief that they are, in certain instances at least, by some means or other, able to communicate with the world of humanity. The more numerous part of mankind cannot form in their mind the idea of the spirit of the deceased existing, without possessing or having the power to assume the appearance which their acquaintance bore during his life, and do not push their researches beyond this point.
