Upon some occasions, indeed, we both punish and approve of punishment, merely from a view to the general interest of society, which, we imagine, cannot otherwise be secured. Of this kind are all the punishments inflicted for breaches of what is called either civil police, or military discipline. Such crimes do not immediately or directly hurt any particular person; but their remote consequences, it is supposed, do produce, or might produce, either a considerable inconveniency, or a great disorder in the society. A sentinel, for example, who falls asleep upon his watch, suffers death by the laws of war, because such carelessness might endanger the whole army. This severity may, upon many occasions, appear necessary, and, for that reason, just and proper. When the preservation of an individual is inconsistent with the safety of a multitude, nothing can be more just than that the many should be preferred to the one. Yet this punishment, how necessary soever, always appears to be excessively severe. The natural atrocity of the crime seems to be so little, and the punishment so great, that it is with great difficulty that our heart can reconcile itself to it. Though such carelessness appears very blamable, yet the thought of this crime does not naturally excite any such resentment as would prompt us to take such dreadful revenge. A man of humanity must recollect himself, must make an effort, and exert his whole firmness and resolution, before he can bring himself either to inflict it, or to go along with it when it is inflicted by others. It is not, however, in this manner, that he looks upon the just punishment of an ungrateful murderer or parricide. His heart, in this case, applauds with ardour, and even with transport, the just retaliation which seems due to such detestable crimes, and which, if, by any accident, they should happen to escape, he would be highly enraged and disappointed. The very different sentiments with which the spectator views those different punishments, is a proof that his approbation of the one is far from being founded upon the same principles with that of the other. He looks upon the sentinel as an unfortunate victim, who, indeed, must, and ought to be, devoted to the safety of numbers, but whom still, in his heart, he would be glad to save; and he is only sorry, that the interest of the many should oppose it. But if the murderer should escape from punishment, it would excite his highest indignation, and he would call upon God to avenge, in another world, that crime which the injustice of mankind had neglected to chastise upon earth.
For it well deserves to be taken notice of, that we are so far from imagining that injustice ought to be punished in this life, merely on account of the order of society, which cannot otherwise be maintained, that Nature teaches us to hope, and religion, we suppose, authorises us to expect, that it will be punished, even in a life to come. Our sense of its ill desert pursues it, if I may say so, even beyond the grave, though the example of its punishment there cannot serve to deter the rest of mankind, who see it not, who know it not, from being guilty of the like practices here. The justice of God, however, we think, still requires, that he should hereafter avenge the injuries of the widow and the fatherless, who are here so often insulted with impunity. In every religion, and in every superstition that the world has ever beheld, accordingly, there has been a Tartarus as well as an Elysium; a place provided for the punishment of the wicked, as well as one for the reward of the just.
