Sec. XVI. "If then a city is one continuous entity, so of course is a race that starts from one beginning, that can trace back intimate union and similarity of faculties, for that which is begot is not, like some production of art, unlike the begetter, for it proceeds from him, and is not merely produced by him, so that it appropriately receives his share, whether that be honour or punishment. And if I should not seem to be trifling, I should say that the bronze statue of Cassander melted down by the Athenians, and the body of Dionysius thrown out of their territory by the Syracusans after his death, were treated more unjustly than punishing their posterity would have been. For there was none of the nature of Cassander in the statue, and the soul of Dionysius had left his dead body before this outrage, whereas Nysaeus and Apollocrates,[853] Antipater and Philip,[854] and similarly other sons of wicked parents had innate in them a good deal of their fathers, and that no listless or inactive element, but one by which they lived and were nourished, and by which their ideas were controlled. Nor is it at all strange or absurd that some should have their fathers' characteristics. And to speak generally, as in surgery whatever is useful is also just, and that person would be ridiculous who should say it was unjust to cauterize the thumb when the hip-joints were in pain, and to lance the stomach when the liver was inflamed, or when oxen were tender in their hoofs to anoint the tips of their horns, so he that looks for any other justice in punishment than curing vice, and is dissatisfied if surgery is employed to one part to benefit another, as surgeons open a vein to relieve ophthalmia, can see nothing beyond the evidence of the senses, and does not remember that even a schoolmaster by correcting one lad admonishes others, and that by decimation a general makes his whole army obey. And so not only by one part to another comes benefit, but also to the soul through the soul, even more often than to the body through the body, come certain dispositions, and vices or improvement of character. For just as it is likely in the case of the body that the same feelings and changes will take place, so the soul, being worked upon by fancies, naturally becomes better or worse according as it has more confidence or fear."
