The tender respect of Augustus for a free constitution which he had destroyed, can only be explained by an attentive consideration of the character of that subtle tyrant. A cool head, an unfeeling heart, and a cowardly disposition, prompted him at the age of nineteen to assume the mask of hypocrisy, which he never afterwards laid aside. With the same hand, and probably with the same temper, he signed the proscription of Cicero, and the pardon of Cinna. His virtues, and even his vices, were artificial; and according to the various dictates of his interest, he was at first the enemy, and at last the father, of the Roman world. When he framed the artful system of the Imperial authority, his moderation was inspired by his fears. He wished to deceive the people by an image of civil liberty, and the armies by an image of civil government. I. The death of Cæsar was ever before his eyes. He had lavished wealth and honors on his adherents; but the most favored friends of his uncle were in the number of the conspirators. The fidelity of the legions might defend his authority against open rebellion; but their vigilance could not secure his person from the dagger of a determined republican; and the Romans, who revered the memory of Brutus, would applaud the imitation of his virtue. Cæsar had provoked his fate, as much as by the ostentation of his power, as by his power itself. The consul or the tribune might have reigned in peace. The title of king had armed the Romans against his life. Augustus was sensible that mankind is governed by names; nor was he deceived in his expectation, that the senate and people would submit to slavery, provided they were respectfully assured that they still enjoyed their ancient freedom. A feeble senate and enervated people cheerfully acquiesced in the pleasing illusion, as long as it was supported by the virtue, or even by the prudence, of the successors of Augustus. It was a motive of self-preservation, not a principle of liberty, that animated the conspirators against Caligula, Nero, and Domitian. They attacked the person of the tyrant, without aiming their blow at the authority of the emperor.
