For dexterity in argument, the orator is referred to this school, for the reason given by Quintilian, who says that the custom of supporting an argument on either side of the question, approaches nearest to the orator's practice in forensic causes. _Academiam quidam utilissimam credunt, quod mos in utramque partem disserendi ad exercitationem forensium causarum proximè accedat._ Lib. xii. cap. 2 Quintilian assures us that we are indebted to the academic philosophy for the ablest orators, and it is to that school that Horace sends his poet for instruction: Rem tibi Socraticæ poterunt ostendere chartæ, Verbaque provisam rem non invita sequentur. ARS POET. ver. 310. Good sense, that fountain of the muse's art, Let the rich page of Socrates impart; And if the mind with clear conception glow, The willing words in just expressions flow. FRANCIS'S HORACE. [d] Epicurus made frequent use of the rhetorical figure called exclamation; and in his life, by Diogenes Lærtius, we find a variety of instances. It is for that manner of giving animation to a discourse that Epicurus is mentioned in the Dialogue. For the rest, Quintilian tells us what to think of him. Epicurus, he says, dismisses the orator from his school, since he advises his pupil to pay no regard to science or to method. _Epicurus imprimis nos a se ipse dimittit, qui fugere omnem disciplinam navigatione quam velocissima jubet._ Lib. xii. cap. 2. Metrodorus was the favourite disciple of Epicurus. Brotier says that a statue of the master and the scholar, with their heads joined together, was found at Rome in the year 1743. It is worthy of notice, that except the stoics, who, without aiming at elegance of language, argued closely and with vigour, Quintilian proscribes the remaining sects of philosophers. Aristippus, he says, placed his _summum bonum_ in bodily pleasure, and therefore could be no friend to the strict regimen of the accomplished orator. Much less could Pyrrho be of use, since he doubted whether there was any such thing in existence as the judges before whom the cause must be pleaded. To him the party accused, and the senate, were alike non-entities. _Neque vero Aristippus, summum in voluptate corpora bonum ponens, ad hunc nos laborem adhortetur. Pyrrho quidem, quas in hoc opere partes habere potest? cui judices esse apud quos verba faciat, et reum pro quo loquatur, et senatum, in quo sit dicenda sententia, non liquebat._ Quintil. lib. xii. cap. 2. Section XXXII.
