But ought the just to injure any one at all?
Undoubtedly he ought to injure those who are both wicked and his enemies.
To harm men is to injure them; and to injure them is to make them unjust. But justice cannot produce injustice. When horses are injured, are they improved or deteriorated?
The latter.
Deteriorated, that is to say, in the good qualities of horses, not of dogs?
Yes, of horses.
And dogs are deteriorated in the good qualities of dogs, and not of horses?
Of course.
[C]And will not men who are injured be deteriorated in that which is the proper virtue of man?
Certainly.
