The sad story has been often realized. In the conformation of the heretic by temperament, there is more of intellectual mobility than of strength: a ready perception of analogies gives him both facility and felicity in collecting proofs, or rather illustrations in support of whatever opinion he may adopt. So copious are the materials of conjectural argument which crowd upon him, and so nice is his tact of selection, and so quick his skill of arrangement, that ere dull sobriety has gathered up its weapons, he has reared a most imposing front of defence. Pleased, and even surprised, with his own work, he now confidently maintains a position which at first he scarcely thought to be seriously tenable. Having convinced himself of the certainty of the new truth, and implicated his vanity in its support, deeper motives stimulate the activity of the reasoning and inventive faculties; and he presently piles demonstration upon demonstration, to a most amazing height, until it becomes, in his honest opinion, sheer infatuation to doubt. In this state of mind, of what value are the opinions of teachers and of elders? Of what weight the belief of the catholic church in all ages? They are nothing to be accounted of; there seems even a glory and a heroism, as well as a duty, in spurning the fallible authority of man: modesty, caution, hesitation, are treasons against conscience and heaven!

The young heresiarch, we will suppose to have spent the earliest season of life, while yet the ingenuousness of youth remained unimpaired, in the pursuits of literature or science, and to have been ignorant of Christianity otherwise than as a system of forms and offices. But the moment of awakening arrives; some appalling accident or piercing sorrow sets the interests of time in abeyance, and opens upon the soul the vast objects of immortality. Or the eloquence of a preacher may have effected the change. In these first moments of a new life, the great and common doctrines of religion, perceived in the freshness of novelty, afford scope enough to the ardor of the spirit; and perhaps, also, a new sentiment of submission quells, in some measure, that ardor: the craving of the mind does not yet need heresy; truth has stimulus enough; and even after truth has become somewhat vapid, the restraints of connection and friendship have force to retain the convert three years, or five, in the bosom of humility. But the first accidental contact with doctrinal paradox kindles the constitutional passion, and rouses the slumbering faculties to the full activity of adult vigor; contention ensues; malign sentiments, although perhaps foreign to the temper, are engendered, and these impart gloom to mysticism, and add rancor to extravagance. And now, no dogma that is obnoxious, terrific, intolerant, schismatical, fails to be, in its turn, avowed by the delirious bigot, who burns with ambition to render himself the enemy—not so much of the world, as of the church.

But will even the last extravagance of false doctrine allay the diseased cravings of the brain? Not unless that physical inertness which, towards the middle period of life, sometimes effects a cure of folly, or perhaps some motive of secular interest, supervenes. Otherwise a progression must take place, or a retrogression; and when the heart is sick and faint from the exhaustion of over-activity, and when the whispers of conscience have long ceased to be heard, and when the emotions of genuine piety have become painfully strange to the soul, nothing is so probable as an almost sudden plunge from the pinnacle of high belief, into the bottomless gulf of universal scepticism. A lamentable catastrophe of this kind, and which is only the natural issue of an intellectual enthusiasm, would, no doubt, much oftener take place than it does, if slender reasons of worldly prudence were not usually found to be of firmer texture than all the logic of theology.

A chronic intellectual enthusiasm, when it becomes the source of heresy, most frequently betakes itself to those exaggerations of Christian doctrine which pass under the general designation of Antinomianism;—not the Antinomianism of workshops, which is a corruption of Christianity concocted by mercenary teachers expressly to give license to the sensualities of those by whom they are salaried; but the Antinomianism of the closet, which is a translation into Christian phraseology of the ancient stoicism. The alleged relationship consists, not so much in the similar abuse which is made in both systems of the doctrine of necessity, but in the leading intention of both; which is to inclose the human mind in a perfect envelop of abstractions, such as may effectively defend it from the importunate sense of responsibility, or obligation, and such as shall render him who wears it a passive spectator of his own destinies. The doctrine of fate was seized upon by ancient sophists, and is taken up by the Antinomian, because, better than any other principle, it serves the purposes of this peculiar species of illusory delectation. Yet the Christian theorist has some signal advantages over his ancestor. For example: the egregious absurdities of the ancient philosophist met him on every walk of life, and stood in the way of constant collision with the common sense of mankind: and thus the sage, in spite of his gravity and self-command, could hardly pass a day in public without being put to shame by some glaring proof of practical inconsistency; for as often as he spoke or acted like other men, as often as he made it evident that he did not really think himself a statue or a phantom, he gave the lie direct to the fooleries of his scholastic profession.

But the modern stoic, while, by a sinister inference from his doctrine, he takes large leave of indulgence to the flesh (an indulgence which he uses or not, as his temperament may determine) and so borrows the practical part of Epicureanism, transfers his egregious dogmas to the unseen world, where they come not at all in contact with common sense. In the vast unknown of an eternity on both sides of time, he finds range enough, and immunity, for even the most enormous paradoxes which ingenuity can devise, or sophistry defend. Besides, the argumentative resources of the modern are incomparably more copious and various and tangible than those of the ancient wrangler; for the latter could only fall back, ever and again, upon the same abstractions; but the former may take position on any part of a very wide frontier; for having so large and multifarious a volume as the Scriptures in his hand, and having multiplied the argumentative value of every sentence it contains almost indefinitely by adopting the rule of Origen and the Rabbis, that the whole of Scripture is mystical, and may bear every sense that can be found in it, he is at once secure from the possibility of being confuted, and revels in an unbounded opulence of proof and illustration in support of his positions. To the sober interpreter, the Bible is one book; but to the Antinomian it is as a hundred volumes.

With a field so wide, and means so inexhaustible, the Christian theorist lives in a paradise of speculation; and no revolution to which human nature is liable can be less probable than that which must take place before he abandons his world of factitious happiness. The dreamer must feel that sin is a substantial ill, in which himself is fatally implicated, and not a mere abstraction to be discoursed of; he must learn that the righteous God deals with mankind not fantastically, but on terms adapted to the intellectual and moral conformation of that human nature, of which he is the author; and he must know that salvation is a deliverance, in which man is an agent, not less than a recipient.

It belongs not at all to our subject to attempt a confutation of this, the most strange of the many corruptions which Christianity has undergone; our part is merely to exhibit against the system the charge of delusion or enthusiasm; and this charge needs no other proof than the plain statement that, whereas Christianity recognizes the actual mechanism of human nature, and appeals to the moral sentiments, and urges motives of every class, and labors to enhance the sense of responsibility, and authenticates the voice of conscience, Antinomianism, with indurated arrogance, spurns all such sentiments, and substitutes nothing in their room but bare speculations; and these speculations are all of a kind to cherish the selfish deliriums of luxurious contemplation. But to take a course like this, is, whatever may be the subject in question, the part of an enthusiast. Whoever, in any such manner, cuts himself off from the common sympathies of our nature, and makes idiot sport of the energies of moral action, and has recourse, either to a jargon of sophistries, or to trivial evasions, when other men act upon the intuitions of good sense, and rebuts every idea that does not minister gratification either to fancy or to appetite, such a man must be called an enthusiast, even though he were at the same time—if that were possible—a saint.

We have spoken of the enthusiasm of mysticism. But there is also an enthusiasm of simplification. The lowest intellectual temperature, not less than the highest, admits extravagance, and sometimes even admits it more; for warmth and movement are less unnatural in the world of matter or of mind, than congelation: what so grotesque as the coruscations of frost? If the reasoning faculty had not its imaginative impulse, the sciences would never have moved a step in advance of the mechanic arts; much less would the high theorems of pure mathematics, or the abstruse principles of metaphysics, have been known to mankind. But if this natural and useful impulse be irregular and excessive, it becomes the spring of errors. Yet the perfection of science, and its general diffusion in modern times, operate so effectually to keep in check that propensity to absurd speculation of which the elements are always in existence, that if we are in search of specimens of this species of intellectual disease, we must expect to meet with them only without the pale of education, and among the self-taught philosophers of workshops, who sometimes amuse the hour of stolen leisure in digesting systems of the universe, other than the one which is demonstrated in our universities.

Driven from the enclosures where the demonstrable sciences hold empire, the enthusiasts of speculation turn off upon ground where there is more scope, more obscurity, more license, and less of the stern and instant magistracy of right reason. Some give themselves to politics, some to political economy, and some to theology; and whatever they severally meet with that is in its nature, or that has become concrete, complex, or multifariously involved, they seize upon with a hungry avidity. The disease of the brain has settled upon the faculty of analysis; all things compound must therefore be severed, and not only be severed but left in disunion. It cannot but happen that, in these zealous labors of dissolution, some happy strokes must now and then fall upon errors which wiser men have either not observed, or have spared: mankind owes therefore a petty debt of gratitude to such speculatists for having removed a few excrescences from ancient systems. But these trivial successes, which are hailed with much applause by the vulgar, who delight in witnessing any kind of destruction, and by the splenetic, who believe themselves to gain whatever is torn from others, inspire the heroes of reform with unbounded hopes of effecting universal revolutions; and they actually become inflated to so high a degree of presumption, that, at a time when all the great questions which can occupy the human mind have been thoroughly discussed, and discussed with every advantage of liberty, of learning, and of ability, they are not ashamed to adopt a style of speaking as if they thought themselves morning stars on the verge of the dark ages, destined to usher in the tardy splendors of true philosophy upon a benighted world!

—Or of true religion: as if the Christian doctrine, in its most essential principles, had become extinct, even in the days of the apostles, and had not merely remained under the bushel of superstition during the ages of religious despotism, but long after the chains of that despotism were broken, and after the human mind, with all the vigor and intensity of renovated intelligence and renovated piety had given its utmost force, and its utmost diligence to the exposition of the canon of faith. Of what sort, it might be asked, were this canon, if its meaning on the most important points might, age after age, be utterly misunderstood by ninety-nine learned, honest, and unshackled men, and be perceived only by the one? Yet this is the supposition of simplificators, who from the impulse of a faulty cerebral conformation, must needs disbelieve, because theology would otherwise afford them no intellectual exercise.
