When these general rules, indeed, have been formed, when they are universally acknowledged and established, by the concurring sentiments of mankind, we frequently appeal to them as to the standards of judgment, in debating concerning the degree of praise or blame that is due to certain actions of a complicated and dubious nature. They are upon these occasions commonly cited as the ultimate foundations of what is just and unjust in human conduct; and this circumstance seems to have misled several very eminent authors, to draw up their systems in such a manner, as if they had supposed that the original judgments of mankind with regard to right and wrong, were formed like the decisions of a court of judicatory, by considering first the general rule, and then, secondly, whether the particular action under consideration fell properly within its comprehension. Those general rules of conduct, when they have been fixed in our mind by habitual reflection, are of great use in correcting misrepresentations of self-love concerning what is fit and proper to be done in our particular situation. The man of furious resentment, if he was to listen to the dictates of that passion, would perhaps regard the death of his enemy, as but a small compensation for the wrong, he imagines, he has received; which, however, may be no more than a very slight provocation. But his observations upon the conduct of others, have taught him how horrible all such sanguinary revenges appear. Unless his education has been very singular, he has laid it down to himself as an inviolable rule, to abstain from them upon all occasions. This rule preserves its authority with him, and renders him incapable of being guilty of such a violence. Yet the fury of his own temper may be such, that had this been the first time in which he considered such an action, he would undoubtedly have determined it to be quite just and proper, and what every impartial spectator would approve of. But that reverence for the rule which past experience has impressed upon him, checks the impetuosity of his passion, and helps him to correct the too partial views which self-love might otherwise suggest, of what was proper to be done in his situation. If he should allow himself to be so far transported by passion as to violate this rule, yet even in this case, he cannot throw off altogether the awe and respect with which he has been accustomed to regard it. At the very time of acting, at the moment in which passion mounts the highest, he hesitates and trembles at the thought of what he is about to do: he is secretly conscious to himself that he is breaking through those measures of conduct, which, in all his cool hours, he had resolved never to infringe, which he had never seen infringed by others without the highest disapprobation, and of which the infringement, his own mind forebodes, must soon render him the object of the same disagreeable sentiments. Before he can take the last fatal
