§ i. I am well aware, Cornelius Pulcher, that you prefer the mildest manners in public life, by which you can be at once most useful to the community, and most agreeable in private life to those who have any dealings with you. But since it is difficult to find any region without wild beasts, though it is related of Crete;1 and hitherto there has been no state that has not suffered from envy, rivalry, and strife, the most fruitful seeds of hostility; (for, even if nothing else does, our friendships involve us in enmities, as Chilo2 the wise man perceived, who asked the man who told him he had no enemy, whether he had a friend either), it seems to me that a public man ought not only to examine the whole question of enemies in its various ramifications, but also to listen to the serious remark of Xenophon,3 that a sensible man will receive profit even from his enemies. The ideas therefore that lately occurred to me to deliver, I have now put together nearly in the identical words and send them to you, with the exception of some matter also in "Political Precepts,"4 a treatise which I have often noticed in your hands.
§ ii. People in old times were well satisfied if they were not injured by strange and wild beasts, and that was the only motive of their fights with them, but those of later days have by now learnt to make use of them, for they feed on their flesh, and clothe themselves with their wool, and make medical use of their gall and beestings, and turn their hides into shields, so that we might reasonably fear, if beasts failed man, that his life would become brutish, and wild, and void of resources. Similarly since all others are satisfied with not being injured by their enemies, but the sensible will also (as Xenophon says) get profit out of them, we must not be incredulous, but seek a method and plan how to obtain this advantage, seeing that life without an enemy is impossible.
