2. Secondly, I say, That wherever the conduct of the agent appears to have been entirely directed by motives and affections which we thoroughly enter into and approve of, we can have no sort of sympathy with the resentment of the sufferer, how great soever the mischief which may have been done to him. When two people quarrel, if we take part with, and entirely adopt the resentment of one of them, it is impossible that we should enter into that of the other. Our sympathy with the person whose motives we go along with, and whom therefore we look upon as in the right, cannot but harden us against all fellow-feeling with the other, whom we necessarily regard as in the wrong. Whatever this last, therefore, may have suffered, while it is no more than what we ourselves should have wished him to suffer, while it is no more than what our own sympathetic indignation would have prompted us to inflict upon him, it cannot either displease or provoke us. When an inhuman murderer is brought to the scaffold, though we have some compassion for his misery, we can have no sort of fellow-feeling with his resentment, if he should be so absurd as to express any against either his prosecutor or his judge. The natural tendency of their just indignation against so vile a criminal is indeed the most fatal and ruinous to him. But it is impossible that we should be displeased with the tendency of a sentiment, which, when we bring the case home to ourselves, we feel that we cannot avoid adopting. CHAP. IV. _Recapitulation of the foregoing Chapters._ We do not, therefore, thoroughly and heartily sympathize with the gratitude of one man towards another, merely because this other has been the cause of his good fortune, unless he has been the cause of it from motives which we entirely go along with. Our heart must adopt the principles of the agent, and go along with all the affections which influenced his conduct, before it can entirely sympathize with, and beat time to, the gratitude of the person who has been benefited by his actions. If in the conduct of the benefactor there appears to have been no propriety, how beneficial soever its effects, it does not seem to demand, or necessarily to require, any proportionable recompense.
