But at the same time the aggressive element in the emotion itself has undergone a change, which tends to conceal its true nature by partly leading it into a new channel, or, rather, by narrowing the channel in which it discharges itself. Resentment is directed against the cause of the offence by which it was aroused--broadly speaking, the offender. But when duly reflecting upon the matter, we cannot fail to admit that the real cause was not the offender as a whole, but his will. Deliberate and discriminating resentment is therefore apt to turn against the will rather than against the willer; as we have seen, it is desirous to inflict pain on the offender chiefly as a means of removing the cause of pain suffered, _i.e._, the existence of the bad will. If this is the case with deliberate resentment in general, it must particularly be the case with moral indignation, which is more likely to be {92} influenced by sympathy, and hence more discriminate, than non-moral resentment. This fact gives rise to the moral commandment that we should hate, not the sinner, but the sin. The hostile reaction should be focussed on the will of the offender, and his sensibility should be regarded merely as an instrument through which the will is worked upon. But there is little hope that such a demand can ever be strictly enforced. Professor Sidgwick justly remarks that, though moralists try to distinguish between anger directed "against the act" and anger directed "against the agent," it may be fairly doubted whether it is within the capacity of ordinary human nature to maintain this distinction in practice.[95] The will which offends, and the sensibility which suffers, cannot seriously be looked upon as two different entities the one of which should not be punished for the fault of the other. The person himself is held responsible for the offence. The hostile reaction turns against his will because only by acting upon the will can the cause of pain be removed. But since the remotest ages the aggressive attitude towards this cause has been connected with an instinctive desire to produce counter-pain; and, though we may recognise that such a desire, or rather the volition into which it tends to develop, may be morally justifiable only if it is intended to remove the cause of pain, we can hardly help being indulgent to the gratification of a human instinct which seems to be well nigh ineradicable. It is the instinctive desire to inflict counter-pain that gives to moral indignation its most important characteristic. Without it, moral condemnation and the ideas of right and wrong would never have come into existence. Without it, we should no more condemn a bad man than a poisonous plant. The reason why moral judgments are passed on volitional beings, or their acts, is not merely that they are volitional, but that they are sensitive as well; and however much we try to concentrate our indignation on the
