Institutio Oratoria

I have, therefore, no strong objection even to the views expressed by those who think that some concession should be made to the circumstances under which we speak and to the ears of the audience which require something more polished and emotional than ordinary speech. For this reason I consider that it would be absurd to restrict an orator to the style of the predecessors of Cato and the Gracchi, or even of those orators themselves. And I note that it was the practice of Cicero, while devoting himself in the main to the interests of his case, to take into account the delectation of his audience as well, since, as he pointed out, his own interests were concerned as well as those of his client, although of course the latter were of paramount importance. For his very charm was a valuable asset.
