Moreover, the orator should reach such a pitch of excellence that, while premeditation may still be the safer method, it will not necessarily be the better, since many have acquired the gift of improvisation not merely in prose, but in verse as well, as, for example, Antipater of Sidon and Licinius Archias (for whose powers we have the unquestionable authority of Cicero [*](De Or. iii. 194; Pro Arch. viii. 18. ) ), not to mention the fact that there are many, even in our own day, who have done this and are still doing it. I do not, however, regard this accomplishment as being particularly valuable in itself, for it is both unpractical and unnecessary, but mention it as a useful example to encourage students
Still our confidence in our power of speaking extempore should never be so great that we should neglect to devote a few minutes to the consideration of what we are going to say. There will but rarely be occasions when this is impossible, while in the lawsuits of the courts there is always some time allowed for the purpose. For no one can plead a cause with the facts of which be is unacquainted.
Some declaimers, it is true, are led by a perverse ambition to attempt to speak the moment their theme has been given them, and even ask for a word with which to start, an affectation which is in the worst and most theatrical taste. But eloquence has, in her turn, nothing but derision for those that insult her thus, and speakers who wish to seem learned to fools are merely regarded as fools by the learned.
If, however, chance should impose the necessity upon us of pleading a case at such short notice, we shall require to develop special mental agility, to give all our attention to the subject, and to make a temporary sacrifice of our care for the niceties of language, if we find it impossible to secure both. On such occasions a slower delivery and a style of speaking suggestive of a certain indecision and doubt will secure us time to think, but we must be careful to do this in such a way as to give the impression of thought, not of hesitation.
