That taunts and abuse breed hatred against him who uses them, without yielding him any advantage.
To abstain from threats and injurious language, is, methinks, one of the wisest precautions a man can use. For abuse and menace take nothing from the strength of an adversary; the latter only making him more cautious, while the former inflames his hatred against you, and leads him to consider more diligently how he may cause you hurt.
This is seen from the example of the Veientines, of whom I spoke in the last chapter, who, to the injury of war against the Romans, added those verbal injuries from which all prudent commanders should compel their soldiers to refrain. For these are injuries which stir and kindle your enemy to vengeance, and yet, as has been said, in no way disable him from doing you hurt; so that, in truth, they are weapons which wound those who use them. Of this we find a notable instance in Asia, in connection with the siege of Amida. For Gabade, the Persian general, after besieging this town for a great while, wearied out at last by its protracted defence, determined on withdrawing his army; and had actually begun to strike his camp, when the whole inhabitants of the place, elated by their success, came out upon the walls to taunt and upbraid their enemies with their cowardice and meanness of spirit, and to load them with every kind of abuse. Stung by these insults, Gabade, changing his resolution, renewed the siege with such fury that in a few days he stormed and sacked the town.
