It admits of much question, whether human science can ever find a solid foundation in what relates to the world of spirits. The only instrument of knowledge we can here employ is language. Careful thinkers long ago came to the conclusion, that it is impossible to frame a language precisely and exclusively adapted to convey abstract and spiritual ideas, even if it is possible, as some philosophers have denied, for the mind, in its present state, to have such ideas. All attempts to construct such a language, though made by the most ingenious men, have failed. Language is based upon imagery, and associations drawn from so much of the world as the senses disclose to us; that is, from material objects and their relations. We are here confined, as it were, within narrow walls. We can catch only glimpses of what is above and around us, outside of those walls. Such glimpses may be vouchsafed, from time to time, to rescue us from sinking into materialism, and to keep alive our faith in scenes of existence remaining to be revealed when the barriers of our imprisonment shall be taken down, and what we call death lift us to a clearer and broader vision of universal being.

Of the reality of the spiritual world, we are assured by consciousness and by faith; but our knowledge of that world, so far as it can go into particulars, or become the subject of definition or expression, extends no further than revelation opens the way. In all ages, men have been awakened to the "wonders of the invisible world;" but they remain "wonders" still. Nothing like a permanent, stable, or distinct science has ever been achieved in this department. Man and God are all that are placed within our ken. Metaphysics and Theology are the names given to the sciences that relate to them. The greater the number of books written by human learning and ingenuity to expound them, the more advanced the intelligence and piety of mankind, the less, it is confessed, do we know of them in detail, the more they rise above our comprehension, the more unfathomable become their depths. Experience, history, the progress of light, all increase our sense of the impossibility of estimating the capacities of the human soul. So also we find that the higher we rise towards the Deity, in the contemplation of his works and word, the more does he continue to transcend our power to describe or imagine his greatness and glory. The revelation which the Saviour brought to mankind is all that the heart of man need desire, or the mind of man can comprehend. We are God's children, and he is our Father. That is all; and, the wiser and better we become, the more we are convinced and satisfied that it is enough.

There are, undoubtedly, innumerable beings in the world of spirits, besides departed souls, the Redeemer, and the Father. But of such beings we have, while here, no absolute and specific knowledge. In every age, as well as in our own, there have been persons who have believed themselves to hold communication with unseen spirits. The methods of entering into such communication have been infinitely diversified, from the incantations of ancient sorcery to the mediums and rappings of the present day. In former periods, particularly where the belief of witchcraft prevailed, it was thought that such communications could be had only with evil spirits, and, mostly, with the Chief of evil spirits. They were accordingly treated as criminal, and made the subject of the severest penalties known to the law. In our day, no such penalties are attached to the practice of seeking spiritual communications. Those who have a fancy for such experiments are allowed to amuse themselves in this way without reproach or molestation. It is not charged upon them that they are dealing with the Evil One or any of his subordinates. They do not imagine such a thing themselves. I have no disposition, at any time, in any given case, to dispute the reality of the wonderful stories told in reference to such matters. All that I am prompted ever to remark is, that, if spirits do come, as is believed, at the call of those who seek to put themselves into communication with them, there is no evidence, I venture to suggest, that they are good spirits. I have never heard of their doing much good, substantially, to any one. No important truth has been revealed by them, no discovery been made, no science had its field enlarged; no department of knowledge has been brought into a clearer light; no great interest has been promoted; no movement of human affairs, whether in the action of nations or the transactions of men, has been advanced or in any way facilitated; no impulse has been given to society, and no elevation to life and character. It may be that the air is full of spiritual beings, hovering about us; but all experience shows that no benefit can be derived from seeking their intervention to share with us the duties or the burdens of our present probation. The mischiefs which have flowed from the belief that they can operate upon human affairs, and from attempting to have dealings with them, have been illustrated in the course of our narrative. In this view of the subject, no law is needed to prevent real or pretended communication with invisible beings. Enlightened reflection, common sense, natural prudence, would seem to be sufficient to keep men from meddling at all with practices, or countenancing notions, from which all history proclaims that no good has ever come, but incalculable evil flowed.

For the conduct of life, while here in these bodies, we must confine our curiosity to fields of knowledge open to our natural and ordinary faculties, and embraced within the limits of the established condition of things. Our fathers filled their fancies with the visionary images of ghosts, demons, apparitions, and all other supposed forms and shadows of the invisible world; lent their ears to marvellous stories of communications with spirits; gave to supernatural tales of witchcraft and demonology a wondering credence, and allowed them to occupy their conversation, speculations, and reveries. They carried a belief of such things, and a proneness to indulge it, into their daily life, their literature, and the proceedings of tribunals, ecclesiastical and civil. The fearful results shrouded their annals in darkness and shame. Let those results for ever stand conspicuous, beacon-monuments warning us, and coming generations, against superstition in every form, and all credulous and vain attempts to penetrate beyond the legitimate boundaries of human knowledge.

The phenomena of the real world, so far as science discloses them to our contemplation; the records of actual history; the lessons of our own experience; the utterances of the voice within, audible only to ourselves; and the teachings of the Divine Word,—are sufficient for the exercise of our faculties and the education of our souls during this brief period of our being, while in these bodies. In God's appointed time, we shall be transferred to a higher level of vision. Then, but not before, we may hope for re-union with disembodied spirits, for intercourse with angels, and for a nearer and more open communion with all divine beings.

The principal difference in the methods by which communications were believed to be made between mortals and spiritual beings, at the time of the witchcraft delusion and now, is this. Then it was chiefly by the medium of the eye, but at present by the ear. The "afflicted children" professed to have seen and conversed with the ghosts of George Burroughs's former wives and of others. They also professed to have seen the shapes or appearances of living persons in a disembodied form, or in the likeness of some animal or creature. Now it is affirmed by those calling themselves Spiritualists, that, by certain rappings or other incantations, they can summon into immediate but invisible presence the spirits of the departed, hold conferences with them, and draw from them information not derivable from any sources of human knowledge. There is no essential distinction between the old and the new belief and practice. The consequences that resulted from the former would be likely to result from the latter, if it should obtain universal or general credence, be allowed to mix with judicial proceedings, or to any extent affect the rights of person, property, or character.

The "afflicted children" at Salem Village had, by long practice, become wonderful adepts in the art of jugglery, and probably of ventriloquism. They did many extraordinary things, and were believed to have constant communications with ghosts and spectres; but they did not attain to spiritual rapping. If they had possessed that power, the credulity of judges, ministers, magistrates, and people, would have been utterly overwhelmed, and no limit could have been put to the destruction they might have wrought.

If there was any thing supernatural in the witchcraft of 1692, if any other than human spirits were concerned at all, one thing is beyond a doubt: they were shockingly wicked spirits, and led those who dealt with them to the utmost delusion, crime, and perdition; and this example teaches all who seek to consult with spirits, through a medium or in any other way, to be very strict to require beforehand the most satisfactory and conclusive evidence of good character before they put themselves into communication with them. Spirits who are said to converse with people, in these modern ages, cannot be considered as having much claim to a good repute. No valuable discovery of truth, no important guidance in human conduct, no useful instruction, has ever been conveyed to mankind through them; and much mischief perhaps may have resulted from confiding in them. It is not wise to place our minds under the influence of any of our fellow-creatures, in the ordinary guise of humanity, unless we know something about them entitling them to our acquaintance; much less so, to take them into our intimacy or confidence. Spirits cannot be put under oath, or their credibility be subjected to tests. Whether they are spirits of truth or falsehood cannot be known; and common caution would seem to dictate an avoidance of their company. The fields of knowledge opened to us in the works of mortal men; the stores of human learning and science; the pages of history, sacred or profane; the records of revelation; and the instructions and conversation of the wise and good of our fellow-creatures, while in the body,—are wide enough for our exploration, and may well occupy the longest lifetime.

In its general outlines and minuter details, Salem Witchcraft is an illustration of the fatal effects of allowing the imagination inflamed by passion to take the place of common sense, and of pushing the curiosity and credence of the human mind, in this stage of our being, while in these corporeal embodiments, beyond the boundaries that ought to limit their exercise. If we disregard those boundaries, and try to overleap them, we shall be liable to the same results. The lesson needs to be impressed equally upon all generations and ages of the world's future history. Essays have been written and books published to prove that the sense of the miraculous is destined to decline as mankind becomes more enlightened, and ascribing a greater or less tendency to the indulgence of this sense to particular periods of the church, or systems of belief, or schools of what is called philosophy. It is maintained that it was more prevalent in the mediæval ages than in modern times. Some assert that it has had a greater development in Catholic than Protestant countries; and some, perhaps, insist upon the reverse. Some attempt to show that it has manifested itself more remarkably among Puritans than in other classes of Protestant Christians. The last and most pretentious form of this dogma is, that the sense of the miraculous fades away in the progress of what arrogates to itself the name of Rationalism. This is one of the delusive results of introducing generalization into historical disquisitions. History deals with man. Man is always the same. The race consists, not of an aggregation, but of individuals, in all ages, never moulded or melted into classes. Each individual has ever retained his distinctness from every other. There has been the same infinite variety in every period, in every race, in every nation. Society, philosophy, custom, can no more obliterate these varieties than they can bring the countenances and features of men into uniformity. Diversity everywhere alike prevails. The particular forms and shapes in which the sense of the miraculous may express itself have passed and will pass away in the progress of civilization. But the sense itself remains; just as particular costumes and fashions of garment pass away, while the human form, its front erect and its vision towards the heavens, remains. The sense of the miraculous remains with Protestants as much as with Catholics, with Churchmen as much as with Puritans, with those who reject all creeds, equally with those whose creeds are the longest and the oldest. In our day, it must have been generally noticed, that the wonders of what imagines itself to be Spiritualism are rather more accredited by persons who aspire to the character of rationalists than by those who hold on tenaciously to the old landmarks of Orthodoxy.

The truth is, that the sense of the miraculous has not declined, and never can. It will grow deeper and stronger with the progress of true intelligence. As long as man thinks, he will feel that he is himself a perpetual miracle. The more he thinks, the more will he feel it. The mind which can wander into the deepest depths of the starry heavens, and feel itself to be there; which, pondering over the printed page, lives in the most distant past, communes with sages of hoar antiquity, with prophets and apostles, joins the disciples as they walk with the risen Lord to Emmaus, or mingles in the throng that listen to Paul at Mars' Hill,—knows itself to be beyond the power of space or time, and greater than material things. It knows not what it shall be; but it feels that it is something above the present and visible. It realizes the spiritual world, and will do so more and more, the higher its culture, the greater its freedom, and the wider its view of the material nature by which it is environed, while in this transitory stage of its history.
