Who would call Aeneas pious, if he wished that his native city might be captured, in order that he might save his father from captivity? Who would point to the Sicilian youths as good examples for his children, if they had prayed that Aetna might flame with unusual heat and pour forth a vast mass of fire in order to afford them an opportunity of displaying their filial affection by rescuing their parents from the midst of the conflagration? Rome owes Scipio nothing if he kept the Punic War alive in order that he might have the glory of finishing it; she owes nothing to the Decii if they prayed for public disasters, to give themselves an opportunity of displaying their brave self-devotion. It is the greatest scandal for a physician to make work for himself; and many who have aggravated the diseases of their patients that they may have the greater credit for curing them, have either failed to cure them at all or have done so at the cost of the most terrible suffering to their victims.
