Kitap 3
1.1
There are three things which require special attention in regard to speech: first, the sources of proofs; secondly, style; and thirdly, the arrangement of the parts of the speech. We have already spoken of proofs and stated that they are three in number, what is their nature, and why there are only three; for in all cases persuasion is the result either of the judges themselves being affected in a certain manner, or because they consider the speakers to be of a certain character, or because something has been demonstrated. We have also stated the sources from which enthymemes should be derived—some of them being special, the others general commonplaces.
1.2
We have therefore next to speak of style; for it is not sufficient to know what one ought to say, but one must also know how to say it, and this largely contributes to making the speech appear of a certain character.
1.3
In the first place, following the natural order, we investigated that which first presented itself—what gives things themselves their persuasiveness; in the second place, their arrangement by style; and in the third place, delivery, which is of the greatest importance but has not yet been treated of by anyone. In fact, it only made its appearance late in tragedy and rhapsody, for at first the poets themselves acted their tragedies.Since the authors of tragedies acted their own plays, there was no need for professional actors, nor for instruction in the art of delivery or acting. This explains why no attempt had been made to deal with the question. Similarly, the rhapsodists (reciters of epic poems) were at first as a rule the composers of the poems themselves. It is clear, therefore, that there is something of the sort in rhetoric as well as in poetry, and it has been dealt with by Glaucon of Teos among others.
