Barbarous Humanitarianism

Some quotes from CS Lewis's The Humanitarian Theory of Punishment: 

I urge a return to the traditional or Retributive theory not solely, not even primarily, in the interests of society, but in the interests of the criminal.

According to the Humanitarian theory, to punish a man because he deserves it, and as much as he deserves, is mere revenge, and, therefore, barbarous and immoral. It is maintained that the only legitimate motives for punishing are the desire to deter others by example or to mend the criminal. When this theory is combined, as frequently happens, with the belief that all crime is more or less pathological, the idea of mending tails off into that of healing or curing and punishment becomes therapeutic. Thus it appears at first sight that we have passed from the harsh and self-righteous notion of giving the wicked their deserts to the charitable and enlightened one of tending the psychologically sick. What could be more amiable?

Of all tyrannies a tyranny sincerely exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron’s cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience. They may be more likely to go to Heaven yet at the same time likelier to make a Hell of earth. Their very kindness stings with intolerable insult. To be ‘cured’ against one’s will and cured of states which we may not regard as disease is to be put on a level with those who have not yet reached the age of reason or those who never will; to be classed with infants, imbeciles, and domestic animals. But to be punished, however severely, because we have deserved it, because we ‘ought to have known better’, is to be treated as a human person made in God’s image.

Mercy, detached from Justice, grows unmerciful. That is the important paradox. As there are plants which will flourish only in mountain soil, so it appears that Mercy will flower only when it grows in the crannies of the rock of Justice; transplanted to the marshlands of mere Humanitarianism, it becomes a man-eating weed, all the more dangerous because it is still called by the same name as the mountain variety. But we ought long ago to have learned our lesson. We should be too old now to be deceived by those humane pretensions which have served to usher in every cruelty of the revolutionary period in which we live.
