The lesson of our story will be found not to discard spiritual things, but to teach us, while in the flesh, not to attempt to break through present limitations, not to seek to know more than has been made known of the unseen and invisible, but to keep the inquiries of our minds and the action of society within the bounds of knowledge now attainable, and extend our curious researches and speculations only as far as we can here have solid ground to stand upon.

To explain the superstitious opinions that took effect in the witchcraft delusion, it is necessary to consider the state of biblical criticism at that period. That department of theological learning was then in a very immature condition.

The authority of Scripture, as it appeared on the face of the standard version, seemed to require them to pursue the course they adopted; and those enlarged and just principles of interpretation which we are taught by the learned of all denominations at the present day to apply to the Sacred Writings had not then been brought to the view of the people or received by the clergy.

It was gravely argued, for instance, that there was nothing improbable in the idea that witches had the power, in virtue of their compact with the Devil, of riding aloft through the air, because it is recorded, in the history of our Lord's temptation, that Satan transported him in a similar manner to the pinnacle of the temple, and to the summit of an exceedingly high mountain. And Cotton Mather declares, that, to his apprehension, the disclosures of the wonderful operations of the Devil, upon and through his subjects, that were made in the course of the witchcraft prosecutions, had shed a marvellous light upon the Scriptures! What a perversion of the Sacred Writings to employ them for the purpose of sanctioning the extravagant and delirious reveries of the human imagination! What a miserable delusion, to suppose that the Word of God could receive illumination from the most absurd and horrible superstition that ever brooded in darkness over the mind of man!

One of the sources of the delusion of 1692 was ignorance of many natural laws that have been revealed by modern science. A vast amount of knowledge on these subjects has been attained since that time. In our halls of education, in associations for the diffusion of knowledge, and in a diversified and all-pervading popular literature, what was dark and impenetrable mystery then has been explained, accounted for, and brought within the grasp of all minds. The contemplation of the evils brought upon our predecessors by their ignorance of the laws of nature cannot but lead us to appreciate more highly our opportunities to get knowledge in this department. As we advance into the interior of the physical system to which we belong; are led in succession from one revelation of beauty and grandeur to another, and the field of light and truth displaces that of darkness and mystery; while the fearful images that disturbed the faith and bewildered the thoughts of our fathers are dissolving and vanishing, the whole host of spirits, ghosts, and demons disappearing, and the presence and providence of God alone found to fill all scenes and cause all effects,—our hearts ought to rise to him in loftier adoration and holier devotion. If, while we enjoy a fuller revelation of his infinite and all-glorious operations and designs than our fathers did, the sentiment of piety which glowed in their hearts like a coal from the altar of God has been permitted to grow dim in ours, no reproach their errors and faults can possibly authorize will equal that which will justly fall upon us.

Another cause of their delusion was too great a dependence upon the imagination. We shall find no lesson more clearly taught by history, by experience, or by observation, than this, that man is never safe while either his fancy or his feeling is the guiding principle of his nature. There is a strong and constant attraction between his imagination and his passions; and, if either is permitted to exercise unlimited sway, the other will most certainly be drawn into co-operation with it, and, when they are allowed to act without restraint upon each other and with each other, they lead to the derangement and convulsion of his whole system. They constitute the combustible elements of our being: one serves as the spark to explode the other. Reason, enlightened by revelation and guided by conscience, is the great conservative principle: while that exercises the sovereign power over the fancy and the passions, we are safe; if it is dethroned, no limit can be assigned to the ruin that may follow. In the scenes we have now been called to witness, we have perceived to what lengths of folly, cruelty, and crime even good men have been carried, who relinquished the aid, rejected the counsels, and abandoned the guidance of their reason.

Another influence that operated to produce the catastrophe in 1692 was the power of contagious sympathy. Every wise man and good citizen ought to be aware of the existence and operation of this power. There seems indeed to be a constitutional, original, sympathy in our nature. When men act in a crowd, their heartstrings are prone to vibrate in unison. Whatever chord of passion is struck in one breast, the same will ring forth its wild note through the whole mass. This principle shows itself particularly in seasons of excitement, and its power rises in proportion to the ardor and zeal of those upon whom it acts. It is for every one who desires to be preserved from the excesses of popular feeling, and to prevent the community to which he belongs from plunging into riotous and blind commotions, to keep his own judgment and emotions as free as possible from a power that seizes all it can reach, draws them into its current, and sweeps them round and round like the Maelstrom, until they are overwhelmed and buried in its devouring vortex. When others are heated, the only wisdom is to determine to keep cool; whenever a people or an individual is rushing headlong, it is the duty of patriotism and of friendship to check the motion.

In this connection it may be remarked—and I should be sorry to bring the subject to a close without urging the thought upon your attention—that the mere power of sympathy, the momentum with which men act in a crowd, is itself capable of convulsing society and overthrowing all its safeguards, without the aid or supposed agency of supernatural beings. The early history of the colony of New York presents a case in point.

In 1741, just half a century after the witchcraft prosecutions in Massachusetts, the city of New York, then containing about nine thousand inhabitants, witnessed a scene quite rivalling, in horror and folly, that presented here. Some one started the idea, that a conspiracy was on foot, among the colored portion of the inhabitants, to murder the whites. The story was passed from one to another. Although subsequently ascertained to have been utterly without foundation, no one stopped to inquire into its truth, or had the wisdom or courage to discountenance its circulation. Soon a universal panic, like a conflagration, spread through the whole community; and the results were most frightful. More than one hundred persons were cast into prison. Four white persons and eighteen negroes were hanged. Eleven negroes were burned at the stake, and fifty were transported into slavery. As in the witchcraft prosecutions, a clergyman was among the victims, and perished on the gallows.

The "New-York Negro Plot," as it was called, was indeed marked by all the features of absurdity in the delusion, ferocity in the popular excitement, and destruction along the path of its progress, which belonged to the witchcraft proceedings here, and shows that any people, given over to the power of contagious passion, may be swept by desolation, and plunged into ruin.
