No one of those who have laid down rules for oratory has ever doubted that it is an art. It is clear even from the titles of their books that their theme is the art of rhetoric, while Cicero [*](de Inv. I. v. 6. The titles in question are such as Ars rhetorica, Ars Hermagorae, etc. ) defines rhetoric as artistic eloquence. And it is not merely the orators who have claimed this distinction for their studies with a view to giving them an additional title to respect, but the Stoic and Peripatetic philosophers for the most part agree with them.
Indeed I will confess that I had doubts as to whether I should discuss this portion of my inquiry, for there is no one, I will not say so unlearned, but so devoid of ordinary sense, as to hold that building, weaving or moulding vessels from clay are arts, and at the same time to consider that rhetoric, which, as I have already said, is the noblest and most sublime of tasks, has reached such a lofty eminence without the assistance of art.
For my own part I think that those who have argued against this view did not realise what they were saying, but merely desired to exercise their wits by the selection of a difficult theme, like Polycrates, when he praised Busiris and Clytemnestra; I may add that he is credited with a not dissimilar performance, namely the composition of a speech which was delivered against Socrates.
