Resentment seems to have been given us by nature for defence, and for defence only. It is the safeguard of justice and the security of innocence. It prompts us to beat off the mischief which is attempted to be done to us, and to retaliate that which is already done; that the offender may be made to repent of his injustice, and that others, through fear of the like punishment, may be terrified from being guilty of the like offence. It must be reserved therefore for these purposes, nor can the spectator ever go along with it when it is exerted for any other. But the mere want of the beneficent virtues, though it may disappoint us of the good which might reasonably be expected, neither does, nor attempts to do, any mischief from which we can have occasion to defend ourselves. There is however another virtue, of which the observance is not left to the freedom of our own wills, which may be extorted by force, and of which the violation exposes to resentment, and consequently to punishment. This virtue is justice: the violation of justice is injury: it does real and positive hurt to some particular persons, from motives which are naturally disapproved of. It is, therefore, the proper object of resentment, and of punishment, which is the natural consequence of resentment. As mankind go along with, and approve of, the violence employed to avenge the hurt which is done by injustice, so they much more go along with, and approve of, that which is employed to prevent and beat off the injury, and to restrain the offender from hurting his neighbours. The person himself who meditates an injustice is sensible of this, and feels that force may, with the utmost propriety, be made use of, both by the person whom he is about to injure, and by others, either to obstruct the execution of his crime, or to punish him when he has executed it. And upon this is founded that remarkable distinction between justice and all the other social virtues, which has of late been particularly insisted upon by an author of very great and original genius, that we feel ourselves to be under a stricter obligation to act according to justice, than agreeably to friendship, charity, or generosity; that the practice of these last mentioned virtues seems to be left in some measure to our own choice, but that, somehow or other, we feel ourselves to be in a peculiar manner tied, bound, and obliged to the observation of justice. We feel, that is to say, that force may, with the utmost propriety and with the approbation of all mankind, be made use of to constrain us to observe the rules of the one, but not to follow the precepts of the other.
