It may seem strange that theories which are open to such objections should have been able to attract so many intelligent partisans. These theories must at least possess a certain plausibility. If punishment on the one hand springs from moral indignation, and on the other hand is frequently interpreted as a means either of deterring from crime or of reforming the criminal, there must obviously be some connection between these ends and the retributive aim of moral resentment. There must be certain facts which, to some extent, fill up the gap between the theory of retribution and the other theories of punishment. {84} The doctrine of determent regards punishment as a means of preventing crime. A crime always involves the infliction of pain; and the one thing which men try to prevent for its own sake is pain. The one thing which arouses resentment is likewise pain. There must consequently be a general coincidence between the acts which people resent and the acts which the law would punish if it were framed on the principle of determent. But the resemblance between the desire to deter and resentment is greater still. Resentment is not only aroused by pain, but is a hostile attitude towards its cause, and its intrinsic object is to remove this cause, that is, to prevent pain. An act of moral resentment is therefore apt to resemble a punishment inflicted with a view to deterring from crime, provided that the punishment is directed against the cause of crime--the criminal himself--and is not unduly severe. The doctrine of reformation aims at the removal of a criminal disposition of mind by improving the offender. Moral resentment likewise aims at the removal of a volitional cause of pain, by bringing about repentance in the offender. That repentance ought to be followed by forgiveness, partial or total, is a widely recognised moral claim.
