'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 or bigoted prejudice. It is systematic, ostentatious in error, closes up the avenues of knowledge, and 'shuts the gates of wisdom on mankind.' It is not enough to show that there is no reason for a thing that we do not see the reason of it: if the common feeling, if the involuntary prejudice sets in strong in favour of it, if, in spite of all we can do, there is a lurking suspicion on the side of our first impressions, we must try again, and believe that truth is mightier than we. So, in ordering a definition of any subject, if we feel a misgiving that there is any fact or circumstance emitted, but of which we have only a vague apprehension, like a name we cannot recollect, we must ask for more time, and not cut the matter short by an arrogant assumption of the point in dispute. Common sense thus acts as a check-weight on sophistry, and suspends our rash and superficial judgments. On the other hand, if not only no reason can be given for a thing, but every reason is clear against it, and we can account from ignorance, from authority, from interest, from different causes, for the prevalence of an opinion or sentiment, then we have a right to conclude that we have mistaken a prejudice for an instinct, or have confounded a false and partial impression with the fair and unavoidable inference from general observation. Mr. Burke said that we ought not to reject every prejudice, but should separate the husk of prejudice from the truth it encloses, and so try to get at the kernel within; and thus far he was right. But he was wrong in insisting that we are to cherish our prejudices 'because they are prejudices': for if all are well founded, there is no occasion to inquire into their origin or use; and he who sets out to philosophise upon them, or make the separation Mr. Burke talks of in this spirit and with this previous determination, will be very likely to mistake a maggot or a rotten canker for the precious kernel of truth, as was indeed the case with our Political sophist.

There is nothing more distinct than common sense and vulgar opinion. Common sense is only a judge of things that fall under common observation, or immediately come home to the business and bosoms of men. This is of the very essence of its principle, the basis of its pretensions. It rests upon the simple process of feeling,—it anchors in experience. It is not, nor it cannot be, the test of abstract, speculative opinions. But half the opinions and prejudices of mankind, those which they hold in the most unqualified approbation and which have been instilled into them under the strongest sanctions, are of this latter kind, that is, opinions not which they have ever thought, known, or felt one tittle about, but which they have taken up on trust from others, which have been palmed on their understandings by fraud or force, and which they continue to hold at the peril of life, limb, property, and character, with as little warrant from common sense in the first instance as appeal to reason in the last. The ultima ratio regum proceeds upon a very different plea. Common sense is neither priestcraft nor state-policy. Yet 'there's the rub that makes absurdity of so long life,' and, at the same time, gives the sceptical philosophers the advantage over us. Till nature has fair play allowed it, and is not adulterated by political and polemical quacks (as it so often has been), it is impossible to appeal to it as a defence against the errors and extravagances of mere reason. If we talk of common sense, we are twitted with vulgar prejudice, and asked how we distinguish the one from the other; but common and received opinion is indeed 'a compost heap' of crude notions, got together by the pride and passions of individuals, and reason is itself the thrall or manumitted slave of the same lordly and besotted masters, dragging its servile chain, or committing all sorts of Saturnalian licenses, the moment it feels itself freed from it.—If ten millions of Englishmen are furious in thinking themselves right in making war upon thirty millions of Frenchmen, and if the last are equally bent upon thinking the others always in the wrong, though it is a common and national prejudice, both opinions cannot be the dictate of good sense; but it may be the infatuated policy of one or both governments to keep their subjects always at variance. If a few centuries ago all Europe believed in the infallibility of the Pope, this was not an opinion derived from the proper exercise or erroneous direction of the common sense of the people; common sense had nothing to do with it—they believed whatever their priests told them. England at present is divided into Whigs and Tories, Churchmen and Dissenters; both parties have numbers on their side; but common sense and party spirit are two different things. Sects and heresies are upheld partly by sympathy, and partly by the love of contradiction; if there was nobody of a different way of thinking, they would fall to pieces of themselves. If a whole court say the same thing, this is no proof that they think it, but that the individual at the head of the court has said it; if a mob agree for a while in shouting the same watchword, this is not to me an example of the sensus communis, they only repeat what they have heard repeated by others. If indeed a large proportion of the people are in want of food, of clothing, of shelter—if they are sick, miserable, scorned, oppressed—and if each feeling it in himself, they all say so with one voice and one heart, and lift up their hands to second their appeal, this I should say was but the dictate of common sense, the cry of nature. But to waive this part of the argument, which it is needless to push farther,—l believe that the best way to instruct mankind is not by pointing out to them their mutual errors, but by teaching them to think rightly on indifferent matters, where they will listen with patience in order to be amused, and where they do not consider a definition or a syllogism as the greatest injury you can offer them.

There is no rule for expression. It is got at solely by feeling, that is, on the principle of the association of ideas, and by transferring what has been found to hold good in one case (with the necessary modifications) to others. A certain look has been remarked strongly indicative of a certain passion or trait of character, and we attach the same meaning to it or are affected in the same pleasurable or painful manner by it, where it exists in a less degree, though we can define neither the look itself nor the modification of it. Having got the general clue, the exact result may be left to the imagination to vary, to extenuate or aggravate it according to circumstances. In the admirable profile of Oliver Cromwell after ——, the drooping eyelids, as if drawing a veil over the fixed, penetrating glance, the nostrils somewhat distended, and lips compressed so as hardly to let the breath escape him, denote the character of the man for high-reaching policy and deep designs as plainly as they can be written. How is it that we decipher this expression in the face? First, by feeling it. And how is it that we feel it? Not by re-established rules, but by the instinct of analogy, by the principle of association, which is subtle and sure in proportion as it is variable and indefinite. A circumstance, apparently of no value, shall alter the whole interpretation to be put upon an expression or action and it shall alter it thus powerfully because in proportion to its very insignificance it shows a strong general principle at work that extends in its ramifications to the smallest things. This in fact will make all the difference between minuteness and subtlety or refinement; for a small or trivial effect may in given circumstances imply the operation of a great power. Stillness may be the result of a blow too powerful to be resisted; silence may be imposed by feelings too agonising for utterance. The minute, the trifling and insipid is that which is little in itself, in its causes and its consequences; the subtle and refined is that which is slight and evanescent at first sight, but which mounts up to a mighty sum in the end, which is an essential part of an important whole, which has consequences greater than itself, and where more is meant than meets the eye or ear. We complain sometimes of littleness in a Dutch picture, where there are a vast number of distinct parts and objects, each small in itself, and leading to nothing else. A sky of Claude's cannot fall under this censure, where one imperceptible gradation is as it were the scale to another, where the broad arch of heaven is piled up of endlessly intermediate gold and azure tints, and where an infinite number of minute, scarce noticed particulars blend and melt into universal harmony. The subtlety in Shakespear, of which there is an immense deal scattered everywhere up and down, is always the instrument of passion, the vehicle of character. The action of a man pulling his hat over his forehead is indifferent enough in itself, and generally speaking, may mean anything or nothing; but in the circumstances in which Macduff is placed, it is neither insignificant nor equivocal.
