Institutio Oratoria

V. Partition may be defined as the enumeration in order of our own propositions, those of our adversary or both. It is held by some that this is indispensable on the ground that it makes the case clearer and the judge more attentive and more ready to be instructed, if he knows what we are speaking about and what we are going subsequently to speak about.

Others, on the contrary, think that such a course is dangerous to the speaker on two grounds, namely that sometimes we may forget to perform what we have promised and may, on the other hand, come upon something which we have omitted in the partition. But this will never happen to anyone unless he is either a fool or has come into court without thinking out his speech in detail beforehand.
