THREE:It is against crimes affecting the person that punishments are most desirable and their vindictive character most justly displayed. Personal violence calls for personal detention or personal chastisement;[102] and the principle of analogy in punishment is most appropriate in the case of a man who maltreats his wife or abuses his strength against any weakness greater than his own. Punishment in such cases is a demand of natural justice, whether anyone is affected by the example or not, and whether or not the man himself is improved by it. Not only is it the best means of enforcing that personal security which is one of the main functions of the State, but it is an expression of that sense of moral reprobation which is so necessary to the good order of society.But commerce and the interchange of the pleasures of luxury have this drawback, that however many persons are engaged in their production, they yet begin and end with a few, the great majority of men only enjoying the smallest share of them, so that the feeling of misery, which depends more on comparison than on reality, is not prevented. But the principal basis of this happiness I speak of is personal security and liberty under the limitations of the law; with these the pleasures of luxury favour population, and without them they become the instrument of tyranny. As the noblest wild beasts and the freest birds remove to solitudes and inaccessible forests, leaving the fertile and smiling plains to the wiles of man, so men fly from pleasures themselves when tyranny acts as their distributor.
