Theory of Moral Sentiments

The man who acts according to the rules of perfect prudence, of strict justice, and of proper benevolence, may be said to be perfectly virtuous. But the most perfect knowledge of those rules will not alone enable him to act in this manner: his own passions are very apt to mislead him; sometimes to drive him and sometimes to seduce him to violate all the rules which he himself, in all his sober and cool hours, approves of. The most perfect knowledge, if it is not supported by the most perfect self-command, will not always enable him to do his duty.

Some of the best of the ancient moralists seem to have considered those passions as divided into two different classes: first, into those which it requires a considerable exertion of self-command to restrain even for a single moment; and secondly, into those which it is easy to restrain for a single moment, or even for a short period of time; but which, by their continual and almost incessant solicitations, are, in the course of a life, very apt to mislead into great deviations.

Fear and anger, together with some other passions which are mixed or connected with them, constitute the first class. The love of ease, of pleasure, of applause, and of many other selfish gratifications, constitute the second. Extravagant fear and furious anger, it is often difficult to restrain even for a single moment. The love of ease, of pleasure, of applause, and other selfish gratifications, it is always easy to restrain for a single moment, or even for a short period of time; but, by their continual solicitations, they often mislead us into many weaknesses which we have afterwards much reason to be ashamed of. The former set of passions may often be said to drive, the latter, to seduce us from our duty. The command of the former was, by the ancient moralists above alluded to, denominated fortitude, manhood, and strength of mind; that of the latter, temperance, decency, modesty, and moderation.

The command of each of those two sets of passions, independent of the beauty which it derives from its utility; from its enabling us upon all occasions to act according to the dictates of prudence, of justice, and of proper benevolence; has a beauty of its own, and seems to deserve for its own sake a certain degree of esteem and admiration. In the one case, the strength and greatness of the exertion excites some degree of that esteem and admiration. In the other, the uniformity, the equality and unremitting steadiness of that exertion.

The man who, in danger, in torture, upon the approach of death, preserves his tranquility unaltered, and suffers no word, no gesture to escape him which does not perfectly accord with the feelings of the most indifferent spectator, necessarily commands a very high degree of admiration. If he suffers in the cause of liberty and justice, for the sake of humanity and the love of his country, the most tender compassion for his sufferings, the strongest indignation against the injustice of his persecutors, the warmest sympathetic gratitude for his beneficent intentions, the highest sense of his merit, all join and mix themselves with the admiration of his magnanimity, and often inflame that sentiment into the most enthusiastic and rapturous veneration. The heroes of ancient and modern history, who are remembered with the most peculiar favor and affection, are, many of them, those who, in the cause of truth, liberty, and justice, have perished upon the scaffold, and who behaved there with that ease and dignity which became them. Had the enemies of Socrates suffered him to die quietly in his bed, the glory even of that great philosopher might possibly never have acquired that dazzling splendor in which it has been beheld in all succeeding ages. In the English history, when we look over the illustrious heads which have been engraved by Vertue and Howbraken, there is scarce anybody, I imagine, who does not feel that the axe, the emblem of having been beheaded, which is engraved under some of the most illustrious of them; under those of the Sir Thomas Mores, of the
