To free-born people slavery is a most intolerable evil, to avoid which wise men are willing even to die, resisting in a gallant spirit which despises all danger the attacks of those who seek to inflict upon them the domination of a master. Also, an invincible enemy is an intolerable evil. And if the same person be both things at once, namely, a master and an enemy, who can endure such a complication of calamities? For such a person will be possessed of the power of inflicting injury through his authority as a master, and he will be disinclined to pardon any one by reason of his irreconcileable enmity.
