5.1
IX. I now come to the forensic kind of oratory, which presents the utmost variety, but whose duties are no more than two, the bringing and rebutting of charges. Most authorities divide the forensic speech into five parts: the exordium, the statement of facts, the proof, the refutation, and the peroration. To these some have added the partition into heads, proposition and digression, the two first of which form part of the proof.
5.2
For it is obviously necessary to propound what you are going to prove as well as to conclude. Why then, if proposition is a part of a speech, should not conclusion be also? Partition on the other hand is merely one aspect of arrangement, and arrangement is a part of rhetoric itself, and is equally distributed through every theme of oratory and their whole body, just as are invention and style.
5.3
Consequently we must regard partition not as one part of a whole speech, but as a part of each individual question that may be involved. For what question is there in which an orator cannot set forth the order in which he is going to make his points? And this of course is the function of partition. But how ridiculous it is to make each question an aspect of proof, but partition which is an aspect of a question a part of the whole speech.
