But, before any thing can be the proper object of gratitude or resentment, it must not only be the cause of pleasure or pain, it must likewise be capable of feeling them. Without this other quality, those passions cannot vent themselves with any sort of satisfaction upon it. As they are excited by the causes of pleasure and pain, so their gratification consists in retaliating those sensations upon what gave occasion to them; which it is to no purpose to attempt upon what has no sensibility. Animals, therefore, are less improper objects of gratitude and resentment than animated objects. The dog that bites, the ox that gores, are both of them punished. If they have been the causes of the death of any person, neither the public, nor the relations of the slain, can be satisfied, unless they are put to death in their turn: nor is this merely for the security of the living, but, in some measure, to revenge the injury of the dead. Those animals, on the contrary, that have been remarkably serviceable to their masters, become the objects of a very lively gratitude. We are shocked at the brutality of that officer, {87} mentioned in the Turkish Spy, who stabbed the horse that had carried him across an arm of the sea, lest that animal should afterwards distinguish some other person by a similar adventure. But, though animals are not only the causes of pleasure and pain, but are also capable of feeling those sensations, they are still far from being complete and perfect objects, either of gratitude or resentment; and those passions still feel, that there is something wanting to their entire gratification. What gratitude chiefly desires, is not only to make the benefactor feel pleasure in his turn, but to make him conscious that he meets with this reward on account of his past conduct, to make him pleased with that conduct, and to satisfy him that the person upon whom he bestowed his good offices was not unworthy of them. What most of all charms us in our benefactor, is the concord between his sentiments and our own, with regard to what interests us so nearly as the worth of our own character, and the esteem that is due to us. We are delighted to find a person who values us as we value ourselves, and distinguishes us from the rest of mankind, with an attention not unlike that with which we distinguish ourselves. To maintain in him these agreeable and flattering sentiments, is one of the chief ends proposed by the returns we are disposed to make to him. A generous mind often disdains the interested thought of extorting new favours from its benefactor, by what may be called the importunities of its gratitude. But to preserve and to increase his esteem, is an interest which the greatest mind does not think unworthy of its attention. And this is the foundation of what I formerly observed, and when we cannot enter into the motives of our benefactor, when his conduct and character appear unworthy of our
