Again, a narration is of no advantage when, after our case has once been set forth by the opposite party, it is of no importance to relate it a second time or in another manner; or when the whole affair is so clearly comprehended by the hearers, as they believe at least that it can do us no good to give them information respecting it in another fashion. And when this is the case, it is best to abstain from any narration altogether. It is uttered in an unseasonable place, when it is not arranged in that part of the speech in which the case requires it, and concerning this kind of blunder we will speak when we come to mention the arrangement of the speech. For it is the general arrangement of the whole that this affects. It is not related in the manner which the cause requires, when either that point which is advantageous to the opposite party is explained in a clear and elegant manner, or when that which may be of benefit to the speaker is stated in an obscure or careless way. Wherefore, in order that this fault may be avoided, everything ought to be converted by the speaker to the advantage of his own cause by passing over all things which make against it which can be passed over, by touching lightly on those points which are beneficial to the adversary, and by relating those which are advantageous to himself carefully and clearly. And now we seem to have said enough about narration. Let us now pass on in regular order to the arrangement of the different topics. XXII An arrangement of the subjects to be mentioned in an argument, when properly made, renders the whole oration clear and intelligible. There are two parts in such a division, each of which is especially connected with the opening of the cause, and with the arrangement of the whole discussion. One part is that which points out what are the particulars as to which one is in agreement with the opposite party, and also what remains in dispute; and from this there is a certain definite thing pointed out to the hearer, as that to which he should direct his attention. The other part is that in which the explanation of those matters on which we are about to speak, is briefly arranged and pointed out. And this causes the hearer to retain certain things in his mind, so as to understand that when they have been discussed the speech will be ended. At present it seems desirable to mention briefly how it is proper to use each kind of arrangement. And this arrangement points out what is suitable and what is not suitable; its duty is to turn that which is suitable to the advantage of its own side, in this way--"I agree with the opposite party as to the fact, that a mother has been put to death by her son." Again, on the other side.--"We are both agreed that Agamemnon was slain by Clytaemnestra" For in saying this each speaker has laid down that proposition which was suitable, and nevertheless has consulted the advantage of his own side.
