Institutio Oratoria

For just as all kinds of produce are not provided by every country, and as you will not succeed in finding a particular bird or beast, if you are ignorant of the localities where it has its usual haunts or birthplace, as even the various kinds of fish flourish in different surroundings, some preferring a smooth and others a rocky bottom, and are found on different shores and in divers regions (you will for instance never catch a sturgeon or wrasse in Italian waters), so not every kind of argument can be derived from every circumstance, and consequently our search requires discrimination.

Otherwise we shall fall into serious error, and after wasting our labour through lack of method we shall fail to discover the argument which we desire, unless assisted by some happy chance. But if we know the circumstances which give rise to each kind of argument, we shall easily see, when we come to a particular

Firstly, then, arguments may be drawn from persons; for, as I have already said, [*](v. viii. 4.) all arguments fall into two classes, those concerned with things and those concerned with persons, since causes, time, place, occasion, instruments, means and the like are

Nor must we pass by natural disposition, for avarice, anger, pity, cruelty, severity and the like may often be adduced to prove the credibility or the reverse of a given act; it is for instance often asked whether a

We must also consider the personal ambitions of individuals, for instance whether they wish to be thought rich or eloquent, just or powerful. Past life and previous utterances are also a subject for investigation, since we are in the habit of inferring the present from the past. To these some add passion, by which they mean some temporary emotion such as anger or fear; they also add design, which may refer to the past,
