Yet as it is the act of a madman to be angry with inanimate objects, so also is it to be angry with dumb animals, which can do us no wrong because they are not able to form a purpose; and we cannot call anything a wrong unless it be done intentionally. They are, therefore, able to hurt us, just as a sword or a stone may do so, but they are not able to do us a wrong. Yet some men think themselves insulted when the same horses which are docile with one rider are restive with another, as though it were through their deliberate choice, and not through habit and cleverness of handling that some horses are more easily managed by some men than by others. And as it is foolish to be angry with them, so it is to be angry with children, and with men who have little more sense than children: for all these sins, before a just judge, ignorance would be as effective an excuse as innocence.
