All the theories which have refined and exalted humanity, or those which have been devised as alleviations of its mistakes and evils, have been based upon the elementary emotions of disinterestedness, which we feel to constitute the majesty of our nature. Patriotism, as it existed in the ancient republics, was never, as has been supposed, a calculation of personal advantages. When Mutius Scaevola thrust his hand into the burning coals, and Regulus returned to Carthage, and Epicharis sustained the rack silently, in the torments of which she knew that she would speedily perish, rather than betray the conspirators to the tyrant [Footnote: Tacitus.]; these illustrious persons certainly made a small estimate of their private interest. If it be said that they sought posthumous fame; instances are not wanting in history which prove that men have even defied infamy for the sake of good. But there is a great error in the world with respect to the selfishness of fame. It is certainly possible that a person should seek distinction as a medium of personal gratification. But the love of fame is frequently no more than a desire that the feelings of others should confirm, illustrate, and sympathize with, our own. In this respect it is allied with all that draws us out of ourselves. It is the 'last infirmity of noble minds'. Chivalry was likewise founded on the theory of self-sacrifice. Love possesses so extraordinary a power over the human heart, only because disinterestedness is united with the natural propensities. These propensities themselves are comparatively impotent in cases where the imagination of pleasure to be given, as well as to be received, does not enter into the account. Let it not be objected that patriotism, and chivalry, and sentimental love, have been the fountains of enormous mischief. They are cited only to establish the proposition that, according to the elementary principles of mind, man is capable of desiring and pursuing good for its own sake.
