Manifold and admirable are the purposes to which the external signs of passion are made subservient by the author of our nature. What are occasionally mentioned above, make but a part. Several final causes remain to be unfolded; and to this task I apply myself with alacrity. In the first place, the signs of internal agitation that are displayed externally to every spectator, tend to fix the signification of many terms. The only effectual means to ascertain the meaning of any doubtful word, is an appeal to the thing it represents. Hence the ambiguity of words expressive of things that are not objects of external sense; for in that case an appeal is denied. Passion, strictly speaking, is not an object of external sense: but its external signs are; and by means of these signs, passions may be appealed to, with tolerable accuracy. Thus the words that denote our passions, next to those that denote external objects, have the most distinct meaning. Words signifying internal action and the more delicate feelings, are less distinct. This defect with respect to internal action, is what chiefly occasions the intricacy of logic. The terms of that science are far from being sufficiently ascertained, even after the care and labour bestowed by an eminent writer[43]: to whom however the world is greatly indebted, for removing a mountain of rubbish, and moulding the subject into a rational and correct form. The same defect is remarkable in criticism, which has for its object the more delicate feelings. The terms that denote these feelings, are not more distinct than those of logic. To reduce this science of criticism to any regular form, has never once been attempted. However rich the ore may be, no critical chymist has been found to give us a regular analysis of its constituent parts, and to distinguish each by its own name.
In the second place, society among individuals is greatly promoted by this universal language. The distance and reserve that strangers naturally discover, show its utility. Looks and gestures give direct access to the heart; and lead us to select with tolerable accuracy the persons who may be trusted. It is surprising how quickly, and for the most part how correctly, we judge of character from external appearances.
Thirdly, after social intercourse is commenced, these external signs contribute above all other means to the strictest union, by diffusing through a whole assembly the feelings of each individual. Language no doubt is the most comprehensive vehicle for communicating emotions: but in expedition, as well as in the power of conviction, it falls short of the signs under consideration; the involuntary signs especially, which are incapable of deceit. Where the countenance, the tones, the gestures, the actions, join with the words, in communicating emotions, these united have a force irresistible. Thus all the agreeable emotions of the human heart, with all the social and virtuous affections, are, by means of these external signs, not only perceived but felt. By this admirable contrivance, social intercourse becomes that lively and animating amusement, without which life would at best be insipid. One joyful countenance spreads chearfulness instantaneously through a multitude of spectators.
Fourthly, dissocial passions being hurtful by prompting violence and mischief, are noted by the most conspicuous external signs, in order to put us upon our guard. Thus anger and revenge, especially when suddenly provoked, display themselves on the countenance in legible characters[44]. The external signs again of every passion that threatens danger, raise in us the passion of fear. Nor is this passion occasioned by consciousness of danger, though it may be inflamed by such consciousness. It is an instinctive passion, which operating without reason or reflection, moves us by a sudden impulse to avoid the impending danger[45].
In the fifth place, these external signs are made subservient in a curious manner to the cause of virtue. The external signs of a painful passion that is virtuous or innocent, and consequently agreeable, produce indeed a painful emotion. But this emotion is attractive, and connects the spectator with the person who suffers. Disagreeable passions only, are productive of repulsive emotions involving the spectator’s aversion, and frequently his indignation. This artful contrivance makes us cling to the virtuous and abhor the wicked.
Sixthly, of all the external signs of passion, those of affliction or distress are the most illustrious with respect to a final cause; and deservedly merit a place of distinction. They are illustrious by the singularity of their contrivance; and they are still more illustrious by the sympathy they inspire, a passion to which human society is indebted for its greatest blessing, that of securing relief in all cases of distress. A subject so interesting, ought to be examined with leisure and attention. The conformity of the nature of man to his external circumstances, is in every particular wonderful. His nature makes him prone to society; and his situation makes it necessary for him. In a solitary state he is the most helpless of beings; destitute of support, and in his manifold distresses destitute of relief. Mutual support, the shining attribute of society, being essential to the well-being of man, is not left upon reason, but is inforced even instinctively by the passion of sympathy. Here sympathy makes a capital figure; and contributes, more than any other means, to make life easy and comfortable. But however essential sympathy be to comfortable existence, one thinking of it beforehand, would find difficulty in conjecturing how it could be raised by external signs of distress. For considering the analogy of nature, if these signs be agreeable, they must give birth to a pleasant emotion leading every beholder to be pleased with human misfortunes. If they be disagreeable, as they undoubtedly are, ought not the painful emotion they produce to repel the spectator from them, in order to be relieved from pain? Such would be the conjecture, in thinking of this matter beforehand; and such would be the effect, were man purely a selfish being. But the benevolence of our nature gives a very different direction to the painful passion of sympathy, and to the desire involved in it. Far from flying from distress, we fly to it in order to afford relief; and our sympathy cannot be otherwise gratified than by giving all the succour in our power[46]. Thus external signs of distress, though disagreeable, are attractive; and the sympathy they inspire us with is a powerful cause, impelling us to afford relief even to a stranger as if he were our friend or blood-relation.
This branch of human nature concerning the external signs of passion, is so finely adjusted to answer its end, that those who understand it the best will admire it the most. These external signs, being all of them resolvable into colour, figure, and motion, should not naturally make any deep impression on a spectator. And supposing them qualified for making deep impressions, we have seen above, that the effects they produce are not what would be expected. We cannot therefore account otherwise for the operation of these external signs, than by ascribing it to the original constitution of human nature. To improve the social state, by making us instinctively rejoice with the glad of heart, weep with the mourner, and shun those who threaten danger, is a contrivance illustrious for its wisdom as well as benevolence. With respect to the external signs of distress in particular, to judge of the excellency of their contrivance, we need only reflect upon several other means seemingly more natural, that would not have answered the end proposed. I am attracted by this amusing speculation, and will not ask pardon for indulging in it. We shall in the first place reverse the truth, by putting the case that the external signs of joy were disagreeable, and the external signs of distress agreeable. This is no whimsical supposition; for these external signs, so far as can be gathered from their nature, seem indifferent to the production of pleasure or pain. Admitting then the supposition, the question is, How would our sympathy operate? There is no occasion to deliberate for an answer. Sympathy, upon that supposition, would be not less destructive, than according to the real case it is beneficial. We should be incited, to cross the happiness of others if its external signs were disagreeable to us, and to augment their distress if its external signs were agreeable. I make a second supposition, That the external signs of distress were indifferent to us, and productive neither of pleasure nor pain. This would annihilate the strongest branch of sympathy, that which is raised by means of sight. And it is evident, that reflective sympathy, felt by those only who have more than an ordinary share of sensibility, would be far from being sufficient to fulfil the ends of the social state. I shall approach nearer truth in a third supposition, That the external signs of distress being disagreeable, were productive of a painful repulsive emotion. Sympathy upon this supposition would not be annihilated; but it would be rendered useless. For it would be gratified by flying from or avoiding the object, instead of clinging to it, and affording relief. The condition of man would in reality be worse than if sympathy were totally eradicated; because sympathy would only serve to plague those who feel it, without producing any good to the afflicted.
Loath to quit so interesting a subject, I add a reflection, with which I shall conclude. The external signs of passion are a strong indication, that man, by his very constitution, is framed to be open and sincere. A child, in all things obedient to the impulses of nature, hides none of its emotions: the savage and clown, who have no guide other than pure nature, expose their hearts to view by giving way to all the natural signs: and even when men learn to dissemble their sentiments, and when behaviour degenerates into art, there still remain checks, which keep dissimulation within bounds, and prevent a great part of its mischievous effects. The total suppression of the voluntary signs during any vivid passion, begets the utmost uneasiness, which cannot be endured for any considerable time. This operation becomes indeed less painful by habit: but luckily the involuntary signs, cannot by any effort be suppressed or even dissembled. An absolute hypocrisy, by which the character is concealed and a fictitious one assumed, is made impracticable; and nature has thereby prevented much harm to society. We may pronounce therefore, that nature, herself sincere and candid, intends that mankind should preserve the same character, by cultivating simplicity and truth, and banishing every sort of dissimulation that tends to mischief.
