Again, when the legitimacy of inflicting punishment is admitted, how many conflicting conceptions of justice come to light in discussing the proper apportionment of punishment to offences. No rule on this subject recommends itself so strongly to the primitive and spontaneous sentiment of justice, as the _lex talionis_, an eye for an eye and a tooth for a tooth. Though this principle of the Jewish and of the Mahomedan law has been generally abandoned in Europe as a practical maxim, there is, I suspect, in most minds, a secret hankering after it; and when retribution accidentally falls on an offender in that precise shape, the general feeling of satisfaction evinced, bears witness how natural is the sentiment to which this repayment in kind is acceptable. With many the test of justice in penal infliction is that the punishment should be proportioned to the offence; meaning that it should be exactly measured by the moral guilt of the culprit (whatever be their standard for measuring moral guilt): the consideration, what amount of punishment is necessary to deter from the offence, having nothing to do with the question of justice, in their estimation: while there are others to whom that consideration is all in all; who maintain that it is not just, at least for man, to inflict on a fellow creature, whatever may be his offences, any amount of suffering beyond the least that will suffice to prevent him from repeating, and others from imitating, his misconduct. To take another example from a subject already once referred to. In a co-operative industrial association, is it just or not that talent or skill should give a title to superior remuneration? On the negative side of the question it is argued, that whoever does the best he can, deserves equally well, and ought not in justice to be put in a position of inferiority for no fault of his own; that superior abilities have already advantages more than enough, in the admiration they excite, the personal influence they command, and the internal sources of satisfaction attending them, without adding to these a superior share of the world's goods; and that society is bound in justice rather to make compensation to the less favoured, for this unmerited inequality of advantages, than to aggravate it. On the contrary side it is contended, that society receives more from the more efficient labourer; that his services being more useful, society owes him a larger return for them; that a greater share of the joint result is actually his work, and not to allow his claim to it is a kind of robbery; that if he is only to receive as much as others, he can only be justly required to produce as much, and to give a smaller amount of time and exertion, proportioned to his superior efficiency. Who shall decide between these appeals to conflicting principles of justice? Justice has in this case two sides to it, which it is impossible to bring into harmony, and the two disputants
