Context

“Then a man may be voluntarily harmed and voluntarily suffer what is unjust, but no one is voluntarily treated unjustly; for no one wishes to be unjustly treated, not even the incontinent man. He acts contrary to his wish; for no one wishes for what he does not think to be good, but the incontinent man does do things that he does not think he ought to do. Again, one who gives what is his own, as Homer says Glaucus gave Diomede Armour of gold for brazen, the price of a hundred beeves for nine, is not unjustly treated; for though to give is in his power, to be unjustly treated is not, but there must be some one to treat him unjustly.” source
