Ancient & Medieval Philosophy -- David L. Rouse
And that is the same as what is probable, and is what must occupy the attention of the would-be master of the art of speech. Even actual facts ought sometimes not be stated, if they don't tally with probability; they should be replaced by what is probable, whether in prosecution or defense; whatever you say, you simply must pursue this probability they talk of, and can say good-by to the truth forever. Stick to that all through your speech, and you are equipped with the art complete.
