Table-Talk

probably suggested, has insisted on the same thing, and made rather a perverse use of it in several parts of his Reflections on the French Revolution; and Windham in one of his Speeches has clenched it into an aphorism⁠—“There is nothing so true as habit.” Once more I would say, common sense is tacit reason. Conscience is the same tacit sense of right and wrong, or the impression of our moral experience and moral apprehensions on the mind, which, because it works unseen, yet certainly, we suppose to be an instinct, implanted in the mind; as we sometimes attribute the violent operations of our passions, of which we can neither trace the source nor assign the reason, to the instigation of the Devil!
I shall here try to go more at large into this subject, and to give such instances and illustrations of it as occur to me.
One of the persons who had rendered themselves obnoxious to Government and been included in a charge for high treason in the year 1794, had retired soon after into Wales to write an epic poem and enjoy the luxuries of a rural life. In his peregrinations through that beautiful scenery, he had arrived one fine morning at the inn at Llangollen, in the romantic valley of that name. He had ordered his breakfast, and was sitting at the window in all the dalliance of expectation when a face passed, of which he took no notice at the instant⁠—but when his breakfast was brought in presently after, he found his appetite for it gone⁠—the day had lost its freshness in his eye⁠—he was uneasy and spiritless; and without any cause that he could discover, a total change had taken place in his feelings. While he was trying to account for this odd circumstance, the same face passed again⁠—it was the face of Taylor the spy; and he was longer at a loss to explain the difficulty. He had before caught only a transient glimpse, a passing side-view of the face; but though this was not sufficient to awaken a distinct idea in his memory, his feelings, quicker and surer, had taken the alarm; a string had been touched that gave a jar to his whole frame, and would not let him rest, though he could not at all tell what was the matter with him. To the flitting, shadowy, half-distinguished profile that had glided by his window was linked unconsciously and mysteriously, but inseparably, the impression of the trains that had been laid for him by this person;⁠—in this brief moment, in this dim, illegible shorthand of the mind he had just escaped the speeches of the Attorney and Solicitor-General over again; the gaunt figure of  Mr. Pitt glared by him; the walls of a prison enclosed him; and he felt the hands of the executioner near him, without knowing it till the tremor and disorder of his nerves gave information to his reasoning faculties that all was not well within. That is, the same state of mind was recalled by one circumstance in the series of association that had been produced by the whole set of circumstances at the time, though the manner in which this was done was not immediately perceptible. In other words, the feeling of pleasure or pain, of good or evil, is revived, and acts instantaneously upon the mind, before we have time to recollect the precise objects which have originally given birth to it. 17 The incident here mentioned was merely, then, one case of what the learned understand by the association of ideas: but all that is meant by feeling or common sense is nothing but the different cases of the association of ideas, more or less true to the impression of the original circumstances, as reason begins with the more formal development of those circumstances, or pretends to account for the different cases of the association of ideas. But it does not follow that the dumb and silent pleading of the former (though sometimes, nay often, mistaken) is less true than that of its babbling interpreter, or that we are never to trust its dictates without consulting the express authority of reason. Both are imperfect, both are useful in their way, and therefore both are best together, to correct or to confirm one another. It does not appear that in the singular instance above mentioned, the sudden impression on the mind was superstition or fancy, though it might have been thought so, had it not been proved by the event to have a real physical and moral cause. Had not the same face returned again, the doubt would never have been properly cleared up, but would have remained a puzzle ever after, or perhaps have been soon forgot.⁠—By the law of association as laid down by physiologists, any impression in a series can recall any other impression in that series without going through the whole in order; so that the mind drops the intermediate links, and passes on rapidly and by stealth to the more striking effects of pleasure or pain which have naturally taken the strongest hold of it. By doing this habitually and skillfully with respect to the various impressions and circumstances with which our experience makes us acquainted, it forms a series of unpremeditated conclusions on almost all subjects that can be brought before it, as just as they are of ready application to human life; and common sense is the name of this body of unassuming but practical wisdom. Common sense, however, is an impartial, instinctive result of truth and nature, and will therefore bear the test and abide the scrutiny of the most severe and patient reasoning. It is indeed incomplete without it. By ingrafting reason on feeling, we “make assurance double sure.”
