Consider now, whether any thief, or false accuser, or headstrong neighbor, or rich man enjoying the power conferred by a childless old age, could do any injury to this man, from whom neither war nor an enemy whose profession was the noble art of battering city walls could take away anything. Amid the flash of swords on all sides, and the riot of the plundering soldiery, amid the flames and blood and ruin of the fallen city, amid the crash of temples falling upon their gods, one man was at peace. You need not therefore account that a reckless boast, for which I will give you a surety, if my word goes for nothing. Indeed, you would hardly believe so much constancy or such greatness of mind to belong to any man; but here a man comes forward to prove that you have no reason for doubting that one who is but of human birth can raise himself above human necessities, can tranquilly behold pains, losses, diseases, wounds, and great natural convulsions roaring around him, can bear adversity with calm and prosperity with moderation, neither yielding to the former nor trusting to the latter, that he can remain the same amid all varieties of fortune, and think nothing to be his own save himself, and himself too only as regards his better part.... You have no cause for saying, as you are wont to do, that this wise man of ours is nowhere to be found; we do not invent him as an unreal glory of the human race, or conceive a mighty shadow of an untruth, but we have displayed and will display him just as we sketch him, tho he may perhaps be uncommon, and only one appears at long intervals; for what is great and transcends the common ordinary type is not often produced; but this very Marcus Cato himself, the mention of whom started this discussion, was a man who I fancy even surpassed our model. Moreover, that which hurts must be stronger than that which is hurt. Now wickedness is not stronger than virtue; therefore the wise man can not be hurt. Only the bad attempt to injure the good. Good men are at peace among themselves; bad ones are equally mischievous to the good and to one another. If a man can not be hurt by one weaker than himself, and a bad man be weaker than a good one, and the good have no injury to dread, except from one unlike themselves; then, no injury takes effect upon the wise man; for by this time I need not remind you that no one save the wise man is good....
