XXXII. The Pythagoreans maintain that justice lies in proportioning the punishment to the offence: a rule which cannot be admitted to the full extent of requiring an aggressor to suffer nothing more than a bare requital of the injury he has occasioned. For this is at variance with the most perfect laws, which in cases of theft sometimes require fourfold, and sometimes fivefold restitution to be made. And the Athenian law, besides compelling a thief to pay double the value of what he had taken sentenced him to many days' imprisonment. Among the Indians, as we are informed by Strabo, the person, who had maimed another, was condemned, in addition to the penalty of retaliation, to lose his hand. Nor is it right, as Philo, in explaining the punishment of murder, justly observes, for the suffering of an innocent and guilty person to be exactly the same. And hence it is easy to see why certain crimes not carried into actual execution, and therefore less injurious than those, which are so, are punished only proportionably to the design.--In this manner false witnesses were treated by the Jewish law; and by the Roman law, those who walked ready armed to commit murder. Consequently a greater degree of punishment is due, where the criminal intention is completed. But as death is the severest punishment that can be inflicted, and one that can never be repeated; the sentence of all human law rests there: though by the custom of some countries death is accompanied with torture, in cases of extreme atrocity. XXXIII. In many instances, the magnitude of a punishment can only be measured by the situation of the person on whom it is to be inflicted. Thus a fine imposed upon the poor would be a heavy sentence, though it would scarcely affect the rich; and a man of high rank would feel the weight of a disgrace, that would but lightly touch an ignoble person. Such distinctions are frequently used by the Roman law, often degenerating into acts of partiality; a fault from which the law of Moses is entirely free. And the above rules may be considered as the scale for estimating the different degrees of punishment. XXXIV. Though punishment does not exceed the bounds of justice, yet in certain cases it may be mitigated in favour of a criminal, from motives of mercy, except where such lenity to the guilty is deemed cruelty to the innocent, whose safety is thereby endangered. For the escape of a criminal is often an encouragement to his own perseverance in iniquity, and to that of others, who are encouraged by the example. Necessity indeed requires the sharpest remedies for the suppression of crimes; especially, where the incentives of habit and a facility to commit them prevail.
