From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Even the inaction of the government in its outward relations was doubtless connected with this policy of the nobility, exclusive towards commoners, and distrustful towards the individual members of their own order.
By no surer means could they keep commoners, whose deeds were their patent of nobility, aloof from the pure circles of the aristocracy than by giving no opportunity to any one to perform deeds at all; to the existing government of general mediocrity even an aristocratic conqueror of Syria or Egypt would have proved extremely inconvenient.
