[Footnote 51: Concerning the Dacotahs, Prescott observes, "There are cases where the Indians say retaliation is wrong, and they try to prevent it" (Schoolcraft, _Indian Tribes_, ii. 197).] The aggressive character of moral disapproval has become more disguised, not only by the more scrutinising attitude towards the resentment and retaliation which distinguishes the moral consciousness of a higher type, but by the different way in which the aggressiveness displays itself. The infliction of suffering merely for the sake of retribution is condemned, and the rule is laid down that we should hate, not the sinner, but only the sin. Punishment, which expresses more or less faithfully the moral indignation of the society which inflicts it, is externally similar to an act of revenge; it causes, or is intended {80} to cause, pain in return for inflicted pain. For ages it was looked upon as a matter of course that if a person had committed an offence he should have to suffer for it. This is still the notion of the multitude, as also of a host of theorisers, who, by calling punishment an expiation, or a reparation, or a restoration of the disturbed equilibrium of justice, only endeavour to give a philosophical sanction to a very simple fact, the true nature of which they too often have failed to grasp. The infliction of pain, however, is not an act which the moral consciousness regards with indifference, even in the case of a criminal; and to many enlightened minds with keen sympathy for human suffering, it has appeared both unreasonable and cruel that the State should wilfully torment him to no purpose. But whilst retributive punishment has been condemned, punishment itself has been defended; it is only looked upon in a different light, not as an end by itself, but as a means of attaining an end. It is to be inflicted, not because wrong has been done, but in order that wrong be not done. Its object is held to be, either to deter from crime, or to reform the criminal, or by means of elimination or seclusion, to make it physically impossible for him to commit fresh crimes.
