And generally, can't you teach someone who is making a mistake? Anyone who does wrong has lost sight of their real goal and is confused. And how does their wrongdoing hurt you? You won't find that any of these people you're angry with has actually done anything to harm your mind — which is the only thing that can truly be damaged. Why should it surprise or upset you when someone who doesn't know better acts like someone who doesn't know better? You should blame yourself instead. You had good reason to expect this kind of behavior from this person, but you didn't see it coming. And now you're shocked that it happened.
And generally, is it not in thy power to instruct him better, that is in an error? For whosoever sinneth, doth in that decline from his purposed end, and is certainly deceived, And again, what art thou the worse for his sin? For thou shalt not find that any one of these, against whom thou art incensed, hath in very deed done anything whereby thy mind (the only true subject of thy hurt and evil) can be made worse than it was. And what a matter of either grief or wonder is this, if he that is unlearned, do the deeds of one that is unlearned? Should not thou rather blame thyself, who, when upon very good grounds of reason, thou mightst have thought it very probable, that such a thing would by such a one be committed, didst not only not foresee it, but moreover dost wonder at it, that such a thing should be.
