It must be remembered that at that time there was no established, centralized, sacerdotal authority. Nevertheless, for more than a century, imperial officials, designated for that purpose, had determined the degrees and inflicted the punishment of heresy. Confiscation, banishment, torture, and death threatened all who refused to subscribe to the doctrines which, varying with different reigns, were promulgated as the momentary and uncertain standards of orthodoxy. The incomprehensibility of a dogma was considered an infallible indication of its truth. The philosopher was then, as now, stigmatized as the implacable enemy of religion. A reign of terror overspread the empire. Every scholar became an object of suspicious aversion. His neighbors shunned his company. The clergy anathematized him from the pulpit. Informers dogged his footsteps and intruded upon his privacy. Indifference to religious duties, or an unguarded statement frequently distorted by malice, was a sufficient cause for imprisonment. The discovery of an heretical passage in a volume of his library rarely failed to provoke a sentence of death. Such measures, equivalent to a proscription of knowledge, produced the most lamentable consequences. Literary occupations became to all intents and purposes criminal. Everywhere valuable collections of books were hastily consigned to the flames by their owners, apprehensive of being compromised by their contents. Oratory, except that of the pulpit, could not survive such restrictions. Public sentiment, controlled by ecclesiastical prejudice, became inimical to the maintenance of even ordinary institutions of learning. A blind reverence for the Church, and a disposition to enforce obedience to its mandates by the merciless employment of the secular arm, were popularly regarded as the duties of every member of society. It was the ominous inauguration of that fearful power which afterwards culminated in the irresponsible despotism of the Vatican.
