The regard to those general rules of conduct, is what is properly called a sense of duty, a principle of the greatest consequence in human life, and the only principle by which the bulk of mankind are capable of directing their actions. Many men behave very decently, and through the whole of their lives avoid any considerable degree of blame, who yet, perhaps, never felt the sentiment upon the propriety of which we found our approbation of their conduct, but acted merely from a regard to what they saw were the established rules of behaviour. The man who has received great benefits from another person, may, by the natural coldness of his temper, feel but a very small degree of the sentiment of gratitude. If he has been virtuously educated, however, he will often have been made to observe how odious those actions appear which denote a want of this sentiment, and how amiable the contrary. Tho’ his heart therefore is not warmed with any grateful affection, he will strive to act as if it was, and will endeavour to pay all those regards and attentions to his patron which the liveliest gratitude could suggest. He will visit him regularly; he will behave to him respectfully; he will never talk of him but with expressions of the highest esteem, and of the many obligations which he owes to him. And what is more, he will carefully embrace every opportunity of making a proper return for past services. He may do all this too without any hypocrisy or blamable dissimulation, without any selfish intention of obtaining new favours, and without any design of imposing either upon his benefactor or the public. The motive of his actions may be no other than a reverence for the established rule of duty, a serious and earnest desire of acting, in every respect, according to the law of gratitude. A wife, in the same manner, may sometimes not feel that tender regard for her husband which is suitable to the relation that subsists between them. If she has been virtuously educated, however, she will endeavour to act as if she felt it, to be careful, officious, faithful, and sincere, and to be deficient in none of those attentions which the sentiment of conjugal affection could have prompted her to perform. Such a friend, and such a wife, are neither of them, undoubtedly, the very best of their kinds; and though both of them may have the most serious and earnest desire to fulfil every part of their duty, yet they will fail in many nice and delicate regards, they will miss many opportunities of obliging, which they could never have overlooked if they had possessed the sentiment that is proper to their situation. Though not the very first of their kinds, however, they are perhaps the second; and if the regard to the general rules of conduct has been very strongly impressed upon them, neither of them will fail in any essential part of their duty. None but those of the happiest mould are capable of suiting, with exact justness, their sentiments and
