From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The Greek school-terminology is throughout and intentionally avoided. Very earnestly the author points out the danger of many teachers, and inculcates the golden rule that the scholar ought above all to be induced by the teacher to help himself; with equal earnestness he recognizes the truth that the school is a secondary, and life the main, matter, and gives in his examples chosen with thorough independence an echo of those forensic speeches which during the last decades had excited notice in the Roman advocate-world.
It deserves attention, that the opposition to the extravagances of Hellenism, which had formerly sought to prevent the rise of a native Latin rhetoric,(37) continued to influence it after it arose, and thereby secured to Roman eloquence, as compared with the contemporary eloquence of the Greeks, theoretically and practically a higher dignity and a greater usefulness.
37. Cf. IV. XII. Course of Literature and Rhetoric
