Institutio Oratoria

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.

Consequently, in panegyric, funeral orations excepted, in returning thanks, exhortations and the like, the delivery must be luxuriant, magnificent, and grand. On the other hand, in funeral or consolatory speeches, together with most of those in defence of accused persons, the delivery will be melancholy and subdued. When we speak in the senate, it will be authoritative, when we address the people, dignified, and when we are pleading in private cases, restrained.

There are three qualities which delivery should possess. It should be conciliatory, persuasive and moving, and the possession of these three qualities involves charm as a further requisite. A conciliatory effect may be secured either by charm of style or by producing an impression of excellence of character, which is in some mysterious way clearly revealed both by voice and gesture. A persuasive effect, on the other hand, is produced by the power of assertion, which is sometimes more convincing even than actual proof.
