If, then, any one in passion brings a charge rashly against any one, mere abuse is not to be taken for an accusation. But a certain time being allowed for dealing with the matter, the person should profess his ability in writing to prove what he has alleged in passion; so that, if he should happen to think better of the things he uttered in passion, and decline to repeat or write them, the person may not be held as charged with the crime. Every one, therefore, who adduces a charge, ought to state in writing his ability to prove it. And, indeed, a cause should always be dealt with in the place where the charge is admitted; and the man who fails to substantiate his allegation, should himself bear the penalty which he advanced.
