Imagination is said to be the simple apprehension of corporeal objects when they are absent; which absence of the object it contemplates, distinguishes this faculty from sensation, and has occasioned some metaphysicians to call it recorded sensation. Upon the due regulation, and proper management, of this great and extraordinary power of the mind, depends, in a great measure, the happiness or misery of life. It ought to consist of a happy combination of those ideas we receive through the organs of bodily sense, and those which we derive from the faculties of moral perception; but it too frequently consists of a capricious and ill-formed mixture of heterogeneous images, which though true in themselves, are false in the way they are applied. Thus a person, the circulation of whose blood in any particular member is suddenly stopped, imagines that needles are pricking the disordered part. The sensation in this case is real, but the conclusion from it is fallacious. So in every mental illusion, imagination, when she first begins to exercise her powers, seizes on some fact, of the real nature of which the mind has but an obscure idea, and, for want of tracing it through all its connexions and dependences, misleads reason into the darkest paths of error. The wild conjectures, and extravagant opinions which have issued from this source are innumerable. The imagination receives every impulse with eagerness, while the passions crowd around her splendid throne, obedient to her dictates. They act, indeed, reciprocally on each other. The imagination pours a concourse of contrary ideas into the mind, and easily disregards, or reconciles their incongruities. The voice of the calm inquirer, reason, is incapable of being heard amidst the tumult; and the favorite image is animated and enlarged by the glowing fire of the passions. No power remains to control or regulate, much less to subdue, this mental ray, which inflames the whole soul, and exalts it into the fervor of enthusiasm, hurries it into the extravagance of superstition: or precipitates it into the furious frenzies of fanaticism.

The powerful tumult reigns in every part,

Pants in the breast, and swells the rising heart.

Enthusiasm is that ecstacy of the mind, that lively transport of the soul, which is excited by the pursuit or contemplation of some great and noble object, the novelty of which awakens attention, the truth of which fixes the understanding, and the grandeur of which, by firing the fancy, engages the aid of every passion, and prompts the mind to the highest undertakings. A just and rightly formed enthusiasm is founded in reason, and supported by nature, and carries the mind above its ordinary level, into the unexplored regions of art and science. The rational enthusiast, indeed, rises to an elevation so far above the distinct view of vulgar eyes, that common understandings are apt to treat him either with blind admiration, or cool contempt, only because they are incapable of comprehending his real character; and while some bow to him as an extraordinary genius, others rail at him as an unhappy lunatic. The powers of enthusiasm, however, when founded upon proper principles, so strengthen and invigorate the faculties of the mind, as to enable it to resist danger undismayed, and to surmount difficulties that appear irresistible. Those, indeed, who have possessed themselves of this power to any extraordinary degree, have been considered as inspired, and their great achievements conceived to have been directed by councils, and sustained by energies of a divine or super-mundane nature. Certain it is, that we owe to the spirit of enthusiasm whatever is great in art, sublime in science, or noble in the human character: and the elegant and philosophic Lord Shaftsbury, while he ridicules the absurdities of this wonderfully powerful and extensive quality, admits that it is impossible to forbear ascribing to it whatever is greatly performed by heroes, statesmen, poets, orators, and even philosophers themselves: and who that is not contented to wallow in the mire of gross sensuality, would not quit the noisy scenes of tumultuous dissipation, and repair with joy and gladness to solitary shades, to the bower of tranquillity, and the fountain of peace, to majestic forests, and to verdant groves, to acquire this necessary ingredient to perfect excellence? Who would not willingly pierce the pensive gloom, or dwell among the brighter glories of the golden age, to acquire by a warm and glowing, but correct and chaste contemplation of the beautiful and sublime works of nature, these ravishing sensations, and gain this noble fervor of the imagination? A proper study of the works of nature amidst the romantic scenery of sylvan solitude, is certainly the most likely means of inspiring the mind with true enthusiasm, and leading genius to her most exalted heights; but the attempt is dangerous. There are few men in whose minds airy notions do not sometimes tyrannize. “To indulge the power of fiction,” says a celebrated writer, “and send imagination out upon the wing, is often the sport of those who delight too much in silent speculation. When we are alone, we are not always busy; the labor of excogitation is too violent to last long; the ardor of inquiry will sometimes give way to idleness or satiety. He who has nothing external that can divert him, must find pleasure in his own thoughts, and must conceive himself what he is not; for who is pleased with what he is? He then expatiates in boundless futurity, and culls from all imaginable conditions that which for the present moment he should most desire, amuses his desires with impossible enjoyments, and confers upon his pride unattainable dominion. The mind dances from scene to scene, unites all pleasures in all combinations, riots in delights which nature and fortune, with all their bounty, cannot bestow. In time some particular train of ideas fixes the attention; all other intellectual gratifications are rejected; the mind in weariness or leisure, recurs constantly to the favorite conception, and feasts on the luscious falsehood whenever she is offended with the bitterness of truth. By degrees the reign of fancy is confirmed; she grows first imperious, and in time despotic: then fictions begin to operate as realities, false opinions fasten on the mind, and life passes in dreams of rapture or of anguish. This is one of the dangers of solitude.”

These observations lead us to consider the character of the fanatical visionary, who feels, like the happy enthusiast, the same agitation of passion, and the same inflammation of mind; but as the feelings of one are founded upon knowledge, truth, and nature, so the feelings of the other are the result of ignorance and error, and all the glittering meteors of his brain the effects of imposture and deception. Of this species of enthusiasm Mr. Locke gives the following description: “In all ages men in whom melancholy has mixed with devotion, or whose conceit of themselves has raised them into an opinion of a greater familiarity with God, and a nearer admittance to his favors, than is afforded to others, have often flattered themselves with a persuasion of an immediate intercourse with the Deity, and frequent communication with his divine spirit. Their minds being thus prepared, whatever groundless opinion comes to settle itself strongly upon their fancies, is an illumination from the Spirit of God, and whatever odd action they find in themselves a strong inclination to do, that impulse is concluded to be a call or direction from heaven, and must be obeyed; it is a commission from above, and they cannot err in executing it. This species of enthusiasm, though arising from the conceit of a warm and overweening brain, works, when it once gets footing, more powerfully on the persuasions and actions of men than either reason, revelation, or both together; men being forwardly obedient to all the impulses they receive from themselves.” The fantastic images, indeed, which the wildness of his imagination creates, subdues his reason, and destroys the best affections of his heart, while his passions take the part of their furious assailants, and render him the victim of his visionary conceptions. It is not, however, from sources of fanatical devotion, or irrational solitude, that this vicious species of enthusiasm alone arises. The follies of faquiers, the extravagance of orgaists, the absurdities of hermits, and the mummery of monks, are not more enthusiastically injurious to the true interests of mankind, or more pregnant with all the calamitous effects of this baleful vice, than those unprincipled systems of politics and morals which have been of late years obtruded on the world, and in which good sense is sacrificed, and true science disgraced.

The growth of fanaticism, whether moral, political, religious, or scientific, is not confined exclusively to any age or country; the seeds of it have been but too plentifully sown in all the regions of the earth; and it is almost equally baneful and injurious in whatever soil they spring. Every bold, turbulent, and intriguing spirit, who has sufficient artifice to inflame the passions of the inconstant multitude, the moment he calls the demon of fanatacism to his aid, becomes troublesome, and frequently dangerous, to the government under which he lives. Even the affectation of this powerful but pernicious quality, is able to produce fermentations, highly detrimental to the peace of society. In the very metropolis of Great Britain, and among the enlightened inhabitants of that kingdom, Lord George Gordon, in the present age, was enabled, by assuming the hypocritical appearance of piety, and standing forth as a champion of a religious sect, to convulse the nation, and endanger its safety. In the twenty-first year of the reign of his Britannic Majesty, the present powerful and illustrious King George III. an act of parliament was passed to relieve the Roman Catholics residing in England from the penalties and disabilities which had been imposed on them at the revolution. An extension of the same relief to the Catholics of Scotland was also said to be intended by parliament. The report spread an immediate alarm throughout the country; societies were formed for the defence of the Protestant faith; committees appointed, books dispersed, and, in short, every method taken to inflame the zeal of the people. These attempts being totally neglected by government, and but feebly resisted by the more liberal minded in the country, produced all their effects. A furious spirit of bigotry and persecution soon showed itself, and broke out into the most outrageous acts of violence against the Papists at Edinburgh, Glasgow, and elsewhere; but as government did not think it advisable to repress this spirit by force, the just and benevolent intentions of the legislature were laid aside. The successful resistance of the zealots in Scotland to any relaxation of the penal laws against the Papists, seems to have given the first rise to the Protestant Association in England; for about the same time bills were dispersed, and advertisements inserted in the newspapers, inviting those who wished well to the cause to unite under that title; and Lord George Gordon, who had been active at the head of the malcontents in Scotland, was chosen their President. The ferment was suffered to increase during a course of several years. His lordship was a member of the senate, and his extraordinary conduct in the house, and frequent interruption he gave to the business of parliament, as well as the unaccountable manner in which he continually brought in and treated matters relative to religion and the danger of popery, and the caprice with which he divided the house upon questions wherein he stood nearly or entirely alone, were passed over, along with other singularities in his dress and manners, rather as subjects of pleasantry than of serious notice or reprehension. On Monday, the 29th of May, 1780, a meeting was held at Coachmaker’s Hall, pursuant to a public advertisement, in order to consider of the mode of presenting a petition to the House of Commons. Lord George Gordon took the chair; and, after a long inflammatory harangue, in which he endeavoured to persuade his hearers of the rapid and alarming progress that popery was making in the kingdom, he proceeded to observe, that the only way to stop it, was going in a firm, manly, and resolute manner to the house and showing their representatives that they were determined to preserve their religious freedom with their lives; that, for his part, he would run all hazards with the people; and if the people were too lukewarm to run all hazards with him, when their conscience and their country called them forth, they might get another president, for that he would tell them candidly, he was not a lukewarm man himself; and that, if they meant to spend their time in mock debate, and idle opposition, they might get another leader. This speech was received with the loudest applause, and his lordship then moved the following resolution: “That the whole body of the Protestant Association do attend in St. George’s Fields, on Friday next, at ten o’clock in the morning, to accompany their president to the House of Commons at the delivery of the Protestant petition;” which was carried unanimously. His Lordship then informed them, that if less than twenty thousand of his fellow citizens attended him on that day, he would not present their petition. Accordingly, on Friday, the 2d day of June, 1780, at ten in the forenoon, several thousands assembled at the place appointed, marshalling themselves in ranks, and waiting for their leader, who arrived about an hour afterward, and they all proceeded to the houses of parliament. Here they began to exercise the most arbitrary power over both lords and commons, by obliging almost all the members to put blue cockades on their hats, and call out “no popery!” Some they compelled to take oaths to vote for the repeal of this obnoxious act; others they insulted in the most indecent and insolent manner. They took possession of all the avenues up to the very door of both houses of parliament, which they twice attempted to force open, and committed many outrages on the persons of the members. Nor were they dispersed, or the remaining members able to leave their seats, until a military force arrived. The houses were adjourned to the 19th of June. But so dreadful a spectacle of calamity and horror was never known in any age or country, as that which the metropolis of England exhibited on the evening and the day which succeeded this seditious congregation. These astonishing effects produced by the real or pretended fanaticism of a simple individual, sufficiently display the power of this dangerous quality, when artfully employed to inflame the passions of the unthinking multitude. But it is worthy of observation, that while this incendiary sustained among his followers the character of a pious patriot, of a man without the smallest spot or blemish, of being, in short, the most virtuous guardian of the established religion of the country, he regularly indulged his holy fervors, and sanctified appearances, every evening, in the company of common prostitutes, or professed wantons.

The fire of fanaticism is, indeed, so subtilely powerful, that it is capable of inflaming the coldest mind. The mildest and the most rational dispositions have been occasionally injured by its heat. The rapidity of its progress certainly depends, in a great degree, on the nature of the materials on which it acts; but, like every dangerous conflagration, its first appearances should be watched, and every means taken to extinguish its flames. The extinction is, perhaps, most happily and readily effected by those counteractions which the common occupations, and daily duties of life produce on the mind, when judiciously opposed to this flagrant evil. Of the advantages, at least, of this resource, a circumstance in the history of the late Dr. Fothergill affords a remarkable example. This celebrated physician possessed the greatest tranquillity of mind, and had obtained so complete a dominion over his passions, that he declared to a friend, recently before his death, that he could not recollect a single instance, during the whole course of his life, in which they had been improperly disturbed. This temper, which perfectly suited to the character of the religion he professed, the tenets of which he strictly practised, he maintained on all occasions; nor was there any thing in his general conduct or manner that betrayed to his most familiar friends the least propensity toward enthusiasm; and yet, distant as the suspicion must be, under these circumstances, that he should ever be under the influence of superstition, it is well known, that while he was a student at Edinburgh, where he was distinguished for the mildness of his manners and the regularity of his conduct, he one day, in an eccentric sally of fanaticism ran, almost entirely naked through the streets of that city, warning all its inhabitants of the impending wrath of heaven; and exhorting them in the most solemn manner, to avert the approaching danger, by humbly imploring the mercy of the offended Deity; but this religious paroxysm was of short duration. He was at this time in habits of intimacy with the great characters who then filled the professional chairs of the university, and ardently engaged in the pursuits of study; and the exercises which his daily tasks required, together with the company and conversation of these rational, well-informed, and thinking men, preserved his reason, and soon restored him to the full and free enjoyment of those faculties, from which both science and humanity afterward derived so many benefits.

The conduct of St. Francis, commonly called the holy Francis of Assisi, was in some degree similar; excepting that the madness of this fanatic continued throughout his life, while the delirium of Fothergill lasted but a day. This saint was born at Assisi, in the province of Umbria, in the year 1182. His real name of baptism was John; but, on account of the facility with which he acquired the French language, so necessary at that time in Italy, especially for the business for which he was intended, he was called Francis. He is said to have been born with the figure of a cross on his right shoulder, and to have dreamt that he was designed by heaven to promote the interests of that holy sign. His disposition was naturally mild, his comprehension quick, his feelings acute, his manners easy, his imagination vivid, and his passions inordinately warm. A careless and unrestrained indulgence of the propensities of youth had led him into a variety of vicious habits and libertine extravagances, until the solitude to which a fit of sickness confined him, brought him to a recollection, and forced him to reflect upon the dangerous tendency of his past misconduct. His mind started with horror at the dreadful scene his retrospection presented to his view; and he resolved to quit the company of his former associates, to reform the profligacy of his life, to restore his character, and to save, by penitence and prayer, his guilty soul. These serious reflections wrought so powerfully on his dejected mind, that he fell into an extravagant kind of devotion, more resembling madness than religion. Fixing on a passage in St. Matthew, in which our Saviour desires his apostles to provide neither gold nor silver, nor brass in their purses; nor scrip for their journey; neither two coats, neither shoes, nor yet staves, he was led to consider a voluntary and absolute poverty as the essence of the gospel, and to prescribe this poverty as a sacred rule, both to himself and to the few who followed him. He accordingly wandered through the streets of Assisi, in garments that scarcely concealed his nakedness, in order, as he said, to inure himself to the taunts and ridicule of his former companions, whom he now called the children of sin, and followers of satan. The father of the young saint, supposing, from these extravagances, that the sickness under which he had so long labored had disordered his intellects, prepared to provide him with some proper place of confinement, until time or medical regimen should restore him to his right senses; but the saint, having been informed of his father’s friendly intention, declined his parental care, and quitting his house, sought a sanctuary in the palace of the bishop of Assisi. The diocesan immediately sent to the father of the fugitive, and, after hearing him upon the subject of his right to provide for the safety of his son, he turned calmly to the son and desired him to reply. The son immediately tore off the tattered garments which he then wore, and casting them with scorn and indignation at the feet of his astonished parent exclaimed, “there, take back all your property. You were, indeed, my earthly father; but henceforth I disclaim you; for I own no father but him who is in heaven.” The bishop, either really or affectedly delighted with this unnatural rant of the young enthusiast, threw his own mantle over the saint, and exhorted him to persevere in his holy resolution, and to cherish with increasing ardor, the divine inspiration of his pious mind. The frantic youth, animated by the warm approbation of the bishop proceeded in his religious course, and abandoning the city, retired into the deepest gloom of an adjacent forest, to indulge the fervors of that false enthusiasm which had overpowered his brain. In this retreat a second vision confirmed him in his holy office; and being encouraged by pope Innocent III, and Honorius, he established, in the year 1209, the Order of Saint Francis. If this ridiculous enthusiast had corrected the extravagances of his overheated imagination, by a cool and temperate exercise of his reason, by studying, like the celebrated physician we have just mentioned, some liberal science, he might, with the talents he possessed, have become a really useful member of society. But these wild shoots, if suffered to grow to any height, cannot afterward be easily eradicated: and even Fothergill, if he had lived like Francis, in an age of superstitious delusion, and had been encouraged to believe the truth of his fanatic conceptions, his temporary frenzy might have continued through life; and his character, instead of being revered as a promoter of an useful science, have been held up by an ignorant multitude to the contempt and ridicule of posterity.

The vacancy of solitude, by leaving the mind to its own ideas, encourages to a great excess these wild and eccentric sallies of the imagination. He who has an opportunity to indulge, without interruption or restraint the delightful musings of an excursive fancy, will soon lose all relish for every other pleasure, and neglect every employment which tends to interrupt the gratification of such an enchanting though dangerous propensity. During the quietude of a sequestered life, imagination usurps the throne of reason, and all the feeble faculties of the mind obey her dictates, until her voice becomes despotic. If the high powers be exercised on the agreeable appearances of nature, and the various entertainments, poetry, painting, music, or any of the elegant arts, are capable of affording,
