Nothing is more intimately related to a man, than his sentiments, words, and actions; and therefore we require here the strictest conformity. When we find what we thus require, we have a lively sense of propriety: when we find the contrary, our sense of impropriety is not less lively. Hence the universal distaste of affectation, which consists in making a shew of greater delicacy and refinement than is suited either to the character or circumstances of the person. Nothing hath a worse effect in a story than impropriety of manners. In Corneille’s tragedy of _Cinna_, Æmilia, a favourite of Augustus, receives daily marks of his affection, and is loaded with benefits; yet all the while is laying plots to assassinate her benefactor, directed by no other motive but to avenge her father’s death[4]. Revenge against a benefactor founded solely upon filial piety, will never suggest unlawful means; because it can never exceed the bounds of justice. And yet the crime here attempted, murder under trust reposed, is what even a miscreant will scarce attempt against his bitterest enemy. What is said may be thought sufficient to explain the qualities of congruity and propriety. But the subject is not exhausted. On the contrary, the prospect enlarges upon us, when we take under view the effects these qualities produce in the mind. Congruity and propriety, where-ever perceived, appear agreeable; and every agreeable object produceth in the mind a pleasant emotion. Incongruity and impropriety, on the other hand, are disagreeable; and consequently produce painful emotions. An emotion of this kind sometimes vanisheth without any consequence; but more frequently is the occasion of other emotions. When any slight incongruity is perceived in an accidental combination of persons or things, as of passengers in a stage-coach or of individuals dining at an ordinary, the emotion of incongruity, after a momentary existence, vanisheth without producing any effect. But this is not the case of propriety and impropriety. Voluntary acts, whether words or deeds, are imputed to the author: when proper, we reward him with our esteem: when improper, we punish him with our contempt. Let us suppose, for example, an heroic action suitable to the character of the author, which raises in him and in every spectator the pleasant emotion of propriety. This emotion generates in the author both self-esteem and joy; the former when he considers his relation to the action, and the latter when he considers the good opinion that others will entertain of him. The same emotion of propriety, produceth in the spectators, esteem for the author of the action: and when they think of themselves, it also produceth, by means of contrast, an emotion of humility. To discover the effects of an unsuitable action, we must invert each of these circumstances. The painful emotion of impropriety, generates in the author of the action both humility and shame; the former when he
