Well, then, if any man should, in addition to the actual virtues which the great orator Demosthenes
v10-12 p.465
possessed, show himself to be the possessor of others, that either owing to his own temperament or the laws of Athens [*]( See II. xvi. 4. Quintilian alludes to an alleged law forbidding Athenian oratos, to appeal to the emotions in the law courts. ) Demosthenes is thought to have lacked, and should reveal in himself the power of strongly stirring the emotions, shall I hear one of these critics protesting that Demosthenes never did this? And if he produces something rhythmically superior (an impossible feat, perhaps, but let us assume it to be so), are we to be told that it is not Attic? These critics would show finer feeling and better judgement, if they took the view that Attic eloquence meant perfect eloquence.
