XVI. The amplification of facts is derived from all the same topics as those arguments which are adduced to create belief. And above all things, a number of accumulated definitions carries weight with it, and a repeated assertion of consequents, and a comparison of contrary and dissimilar facts, and of inconsistent circumstances. Causes too, and those things which arise from causes, and especially similarities and instances, are efficacious; so also are imaginary characters. Lastly, mute things may be introduced as speaking, and altogether all things are to be employed (if the cause will allow of them) which are considered important; and important things are divisible into two classes. For there are some things which seem important by nature, and some by use. By nature, as heavenly and divine things, and those things the causes of which are obscure, as those things which are wonderful on the earth and in the world, from which and from things resembling which, if you only take care, you will be able to draw many arguments for amplifying the dignity of the cause which you are advocating. By use; which appear to be of exceeding benefit or exceeding injury to men; and of these there are three kinds suitable for amplification.
For men are either moved by affection, for instance, by affections for the gods, for their country, or for their parents; or by love, as for their wives, their brothers, their children, or their friends; or by honourableness, as by that of the virtues, and especially of those virtues which tend to promote sociability among men, and liberality. From them exhortations are derived to maintain them; and hatred is excited against, and commiseration awakened for those by whom they are violated.
