It is a curious question to decide how far punishments and rewards may be made effectual to determine the religion of nations and generations of men. They are often unsuccessful. There is a feeling in the human heart, that prompts us to reject with indignation this species of tyranny. We become more obstinate in clinging to that which we are commanded to discard. We place our honour and our pride in the firmness of our resistance. "The blood of the martyrs is the seed of the church." Yet there is often great efficacy in persecution. It was the policy of the court of Versailles that brought almost to nothing the Huguenots of France. And there is a degree of persecution, if the persecuting party has the strength and the inexorableness to employ it, that it is perhaps beyond the prowess of human nature to stand up against.
The mind of the enquiring man is engaged in a course of perpetual research; and ingenuousness prompts us never to be satisfied with the efforts that we have made, but to press forward. But mind, as well as body, has a certain vis inertiae, and moves only as it is acted upon by impulses from without. With respect to the adopting new opinions, and the discovery of new truths, we must be indebted in the last resort, either to books, or the oral communications of our fellow-men, or to ideas immediately suggested to us by the phenomena of man or nature. The two former are the ordinary causes of a change of judgment to men: they are for the most part minds of a superior class only, that are susceptible of hints derived straight from the external world, without the understandings of other men intervening, and serving as a conduit to the new conceptions introduced. The two former serve, so to express it, for the education of man, and enable us to master, in our own persons, the points already secured, and the wisdom laid up in the great magazine of human knowledge; the last imparts to us the power of adding to the stock, and carrying forward by one step and another the improvements of which our nature is susceptible.
It is much that books, the unchanging records of the thoughts of men in former ages, are able to impart to us. For many of the happiest moments of our lives, for many of the purest and most exalted feelings of the human heart, we are indebted to them. Education is their province; we derive from them civilization and refinement; and we may affirm of literature, what Otway has said of woman, "We had been brutes without you." It is thus that the acquisitions of the wise are handed down from age to age, and that we are enabled to mount step after step on the ladder of paradise, till we reach the skies.
But, inestimable as is the benefit we derive from books, there is something more searching and soul-stirring in the impulse of oral communication. We cannot shut our ears, as we shut our books; we cannot escape from the appeal of the man who addresses us with earnest speech and living conviction. It is thus, we are told, that, when Cicero pleaded before Caesar for the life of Ligarius, the conqueror of the world was troubled, and changed colour again and again, till at length the scroll prepared for the condemnation of the patriot fell from his hand. Sudden and irresistible conviction is chiefly the offspring of living speech. We may arm ourselves against the arguments of an author; but the strength of reasoning in him who addresses us, takes us at unawares. It is in the reciprocation of answer and rejoinder that the power of conversion specially lies. A book is an abstraction. It is but imperfectly that we feel, that a real man addresses us in it, and that what he delivers is the entire and deep-wrought sentiment of a being of flesh and blood like ourselves, a being who claims our attention, and is entitled to our deference. The living human voice, with a countenance and manner corresponding, constrains us to weigh what is said, shoots through us like a stroke of electricity, will not away from our memory, and haunts our very dreams. It is by means of this peculiarity in the nature of mind, that it has been often observed that there is from time to time an Augustan age in the intellect of nations, that men of superior powers shock with each other, and that light is struck from the collision, which most probably no one of these men would have given birth to, if they had not been thrown into mutual society and communion. And even so, upon a narrower scale, he that would aspire to do the most of which his faculties are susceptible, should seek the intercourse of his fellows, that his powers may be strengthened, and he may be kept free from that torpor and indolence of soul, which, without external excitement, are ever apt to take possession of us.
The man, who lives in solitude, and seldom communicates with minds of the same class as his own, works out his opinions with patient scrutiny, returns to the investigation again and again, imagines that he had examined the question on all sides, and at length arrives at what is to him a satisfactory conclusion. He resumes the view of this conclusion day after day; he finds in it an unalterable validity; he says in his heart, "Thus much I have gained; this is a real advance in the search after truth; I have added in a defined and palpable degree to what I knew before." And yet it has sometimes happened, that this person, after having been shut up for weeks, or for a longer period, in his sanctuary, living, so far as related to an exchange of oral disquisitions with his fellow-men, like Robinson Crusoe in the desolate island, shall come into the presence of one, equally clear-sighted, curious and indefatigable with himself, and shall hear from him an obvious and palpable statement, which in a moment shivers his sightly and glittering fabric into atoms. The statement was palpable and near at hand; it was a thin, an almost imperceptible partition that hid it from him; he wonders in his heart that it never occurred to his meditations. And yet so it is: it was hid from him for weeks, or perhaps for a longer period: it might have been hid from him for twenty years, if it had not been for the accident that supplied it. And he no sooner sees it, than he instantly perceives that the discovery upon which he plumed himself, was an absurdity, of which even a schoolboy might be ashamed.
A circumstance not less curious, among the phenomena which belong to this subject of belief, is the repugnance incident to the most ingenuous minds, which we harbour against the suddenly discarding an opinion we have previously entertained, and the adopting one which comes recommended to us with almost the force of demonstration. Nothing can be better founded than this repugnance. The mind of man is of a peculiar nature. It has been disputed whether we can entertain more than one idea at a time. But certain it is, that the views of the mind at any one time are considerably narrowed. The mind is like the slate of a schoolboy, which can contain only a certain number of characters of a given size, or like a moveable panorama, which places a given scene or landscape before me, and the space assigned, and which comes within the limits marked out to my perception, is full. Many things are therefore almost inevitably shut out, which, had it not been so, might have essentially changed the view of the case, and have taught me that it was a very different conclusion at which I ought to have arrived.
At first sight nothing can appear more unreasonable, than that I should hesitate to admit the seemingly irresistible force of the argument presented to me. An ingenuous disposition would appear to require that, the moment the truth, or what seems to be the truth, is set before me, I should pay to it the allegiance to which truth is entitled. If I do otherwise, it would appear to argue a pusillanimous disposition, a mind not prompt and disengaged to receive the impression of evidence, a temper that loves something else better than the lustre which all men are bound to recognise, and that has a reserve in favour of ancient prejudice, and of an opinion no longer supported by reason.
In fact however I shall act most wisely, and in the way most honourable to my character, if I resolve to adjourn the debate. No matter how complete the view may seem which is now presented to my consideration, or how irresistible the arguments: truth is too majestic a divinity, and it is of too much importance that I should not follow a delusive semblance that may shew like truth, not to make it in the highest degree proper that I should examine again and again, before I come to the conclusion to which I mean to affix my seal, and annex my sanction, "This is the truth." The ancient Goths of Germany, we are told, had a custom of debating every thing of importance to their state twice, once in the high animation of a convivial meeting, and once in the serene stillness of a morning consultation. Philip of Macedon having decided a cause precipitately, the party condemned by him immediately declared his resolution to appeal from the sentence. And to whom, said the king, wilt thou appeal? To Philip, was the answer, in the entire possession of his understanding.
Such is the nature of the human mind—at least, such I find to be the nature of my own—that many trains of thinking, many chains of evidence, the result of accumulated facts, will often not present themselves, at the time when their presence would be of the highest importance. The view which now comes before me is of a substance so close and well-woven, and of colours so brilliant and dazzling, that other matters in a certain degree remote, though of no less intrinsic importance, and equally entitled to influence my judgment in the question in hand, shall be entirely shut out, shall be killed, and fail to offer themselves to my perceptions.
It is a curious circumstance which Pope, a man of eminent logical power and acuteness, relates, that, having at his command in his youth a collection of all the tracts that had been written on both sides in the reign of James the Second, he applied himself with great assiduity to their perusal, and the consequence was, that he was a Papist and Protestant by turns, according to the last book he read(31).
