I have sketched rapidly, and merely pointed out the most prominent changes. To do even this properly, much more to descend to details, would require greater space than the limits and designs of this work permit. But I think what I have said is sufficient to show that the corruption of public morals, though always a great, is often a transient evil, a malady which may be corrected or which corrects itself, and cannot, therefore, be the sole cause of national ruin, though it may hasten the catastrophe. The corruption of public morals is nearly allied to another evil, which has been assigned as one of the causes of the downfall of empires. It is observed of Athens and Rome, that the glory of these two commonwealths faded about the same time that they abandoned their national creeds. These, however, are the only examples of such a coincidence that can be cited. The religion of Zoroaster was never more flourishing in the Persian empire, than at the time of its downfall. Tyre, Carthage, Judea, the Mexican and Peruvian empires expired at the moment when they embraced their altars with the greatest zeal and devotion. Nay, I do not believe that even at Athens and Rome, the ancient creed was abandoned until the day when it was replaced in every conscience, by the complete triumph of Christianity. I am firmly convinced that, politically speaking, irreligion never existed among any people, and that none ever abandoned the faith of their forefathers, except in exchange for another. In other words, there never was such a thing as a religious interregnum. The Gallic Teutates gave way to the Jupiter of the Romans; the worship of Jupiter, in its turn, was replaced by Christianity. It is true that, in Athens, not long before the time of Pericles, and in Rome, towards the age of the Scipios, it became the fashion among the higher classes, first to reason upon religious subjects, next to doubt them, and finally to disbelieve them altogether, and to pride themselves upon scepticism. But though there were many who joined in the sentiment of the ancient "freethinker" who dared the augurs to look at one another without laughing, yet this scepticism never gained ground among the mass of the people.
