Where there is only one ruling power in the state--be it monarchical, aristocratic, or democratic--this corruption is equally certain, and equally unavoidable. The sonorous periods in which Fontanes celebrated the triumphs of the empire, the impassioned strains in which Robespierre eulogised the incorruptible virtue of the people, the coarse flattery with which O'Connell captivated his ignorant and excitable audiences, equally marked the approach of the period in which oratory, if such a _régime_ continued, must die a natural death. Under such influences it necessarily perished from its own exaggeration: it ceased to be impressive, it became ridiculous. As in all the other arts which are intended to please and instruct mankind, TRUTH, and a regard to the limits of nature, are essential to its success. Exaggeration and hyperbole not only degrade the character of eloquence, but destroy its influence, because they induce a style of expression with which subsequent times, emancipated from passing influences, cannot sympathise--look upon as contemptible. Then, and then only, will oratory attain its highest perfection, during that period "slow to come, soon to perish," as Tacitus said of balanced freedom, during which no one interest in the state is irresistible; and truth, in assailing the vices or resisting the encroachments of others, can find a fulcrum from whence to direct its efforts. Withdraw the fulcrum--remove the support--and truth, and with it genius, will sink to rise no more.
