[10]
Orators, on the contrary, are not permitted the use of such devices; they must use with precision only words in current use and only such ideas as bear upon the actual facts. Besides, the poets compose all their works with meter and rhythm, while the orators do not share in any of these advantages; and these lend such charm that even though the poets may be deficient in style and thoughts, yet by the very spell of their rhythm and harmony they bewitch their listeners.1
