Institutio Oratoria

The considerations with regard to the subject are four in number, of which the first has reference to the case as a whole. For the case may be of a gloomy or a cheerful nature, an anxious business, or one that calls for no alarm, and may involve issues of great or trivial importance. We ought, therefore, never to be so preoccupied over particular portions of a case as to forget to consider the case as a whole.

The second point is concerned with the different aspects of the various portions of the speech, that is, the exordium, statement of facts, arguments and peroration. The third concerns the thoughts, which will vary according to the subject matter and the emotions which we require to awaken. The fourth has reference to the words, which must be given appropriate expression, unless their force is to be entirely wasted, although it is an error to attempt to make our delivery reproduce the sense of every single word.
