We must always, however, carefully distinguish what is only blamable, or the proper object of disapprobation, from what force may be employed either to punish or to prevent. That seems blamable which falls short of that ordinary degree of proper beneficence which experience teaches us to expect of every body; and on the contrary, that seems praise-worthy which goes beyond it. The ordinary degree itself, seems neither blamable nor praise-worthy. A father, a son, a brother, who behaves to the correspondent relation, neither better nor worse than the greater part of men commonly do, seems properly to deserve neither praise nor blame. He who surprises us by extraordinary and unexpected, though still proper and suitable kindness, or on the contrary, by extraordinary and unexpected, as well as unsuitable unkindness, seems praise-worthy in the one case, and blamable in the other. Even the most ordinary degree of kindness or beneficence, however, cannot, among equals, be extorted by force. Among equals each individual is naturally, and antecedent to the institution of civil government, regarded as having a right both to defend himself from injuries, and to exact a certain degree of punishment for those which have been done to him. Every generous spectator not only approves of his conduct when he does this, but enters so far into his sentiments as often to be willing to assist him. When one man attacks, or robs, or attempts to murder another, all the neighbours take the alarm, and think that they do right when they run, either to revenge the person who has been injured, or to defend him who is in danger of being so. But when a father fails in the ordinary degree of parental affection towards a son, when a son seems to want that filial reverence which might be expected to his father; when brothers are without the usual degree of brotherly affection; when a man shuts his breast against compassion, and refuses to relieve the misery of his fellow-creatures, when he can with the greatest ease; in all these cases, though every body blames the conduct, nobody imagines that those who might have reason, perhaps, to expect more kindness, have any right to extort it by force. The sufferer can only complain, and the spectator can intermeddle no other way than by advice and persuasion. Upon all such occasions, for equals to use force against one another, would be thought the highest degree of insolence and presumption.
