XXI. A narration will be probable, if in it those characteristics are visible which are usually apparent in truth; if the dignity of the persons mentioned is preserved; if the causes of the actions performed are made plain; if it shall appear that there were facilities for performing them; if the time was suitable; if there was plenty of room; if the place is shown to have been suitable for the transaction which is the subject of the narration; if the whole business, in short, be adapted to the nature of those who plead, and to the reports bruited about among the common people, and to the preconceived opinions of those who hear. And if these principles be observed, the narration will appear like the truth. But besides all this, it will be necessary to take care that such a narration be not introduced when it will be a hindrance, or when it will be of no advantage; and that it be not related in an unseasonable place, or in a manner which the cause does not require. It is a hindrance, when the very narration of what has been done comes at a time that the hearer has conceived great displeasure at something, which it will be expedient to mitigate by argument, and by pleading the whole cause carefully. And when this is the case, it will be desirable rather to scatter the different portions of the transactions limb by limb as it were over the cause, and, as promptly as may be, to adapt them to each separate argument, in order that there may be a remedy at hand for the wound, and that the defence advanced may at once mitigate the hatred which has arisen.
