if it be not affected, the reasoning is erroneous, because the end is not obtained; the effect itself being the test, and the only test, of the truth and efficacy of the means.
'There is in the commerce of life, as in Art, a sagacity which is far from being contradictory to right reason, and is superior to any occasional exercise of that faculty which supersedes it and does not wait for the slow progress of deduction, but goes at once, by what appears a kind of intuition, to the conclusion. A man endowed with this faculty feels and acknowledges the truth, though it is not always in his power, perhaps, to give a reason for it; because he cannot recollect and bring before him all the materials that gave birth to his opinion; for very many and very intricate considerations may unite to form the principle, even of small and minute parts, involved in, or dependent on, a great many things:—though these in process of time are forgotten, the right impression still remains fixed in his mind.
'This impression is the result of the accumulated experience of our whole life, and has been collected, we do not always know how or when. But this mass of collective observation, however acquired, ought to prevail over that reason, which, however powerfully exerted on any particular occasion, will probably comprehend but a partial view of the subject; and our conduct in life, as well as in the arts, is or ought to be generally governed by this habitual reason: it is our happiness that we are enabled to draw on such funds. If we were obliged to enter into a theoretical deliberation on every occasion before we act, life would be at a stand, and Art would be impracticable.
'It appears to me therefore' (continues Sir Joshua) 'that our first thoughts, that is, the effect which any thing produces on our minds on its first appearance, is never to be forgotten; and it demands for that reason, because it is the first, to be laid up with care. If this be not done, the artist may happen to impose on himself by partial reasoning; by a cold consideration of those animated thoughts which proceed, not perhaps from caprice or rashness (as he may afterwards conceit), but from the fulness of his mind, enriched with the copious stores of all the various inventions which he had ever seen, or had ever passed in his mind. These ideas are infused into his design, without any conscious effort; but if he be not on his guard, he may reconsider and correct them, till the whole matter is reduced to a commonplace invention.
'This is sometimes the effect of what I mean to caution you against; that is to say, an unfounded distrust of the imagination and feeling, in favour of narrow, partial, confined, argumentative theories, and of principles that seem to apply to the design in hand, without considering those general impressions on the fancy in which real principles of sound reason, and of much more weight and importance, are involved, and, as it were, lie hid under the appearance of a sort of vulgar sentiment. Reason, without doubt, must ultimately determine everything; at this minute it is required to inform us when that very reason is to give way to feeling.'(1)
Mr. Burke, by whom the foregoing train of thinking was 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 short-hand 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.(2) 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.'
'Tis the last key-stone that makes up the arch …
Then stands it a triumphal mark! Then men
Observe the strength, the height, the why and when
It was erected; and still walking under,
Meet some new matter to look up, and wonder.
But reason, not employed to interpret nature, and to improve and perfect common sense and experience, is, for the most part, a building without a foundation. The criticism exercised by reason, then, on common sense may be as severe as it pleases, but it must be as patient as it is severe. Hasty, dogmatical, self-satisfied reason is worse than idle fancy
