Why Pagan Symbolism is indestructible?: Because the older a faith, the stronger it clings to the relics of its youth.

The Greeks of the days of Pericles — they who euhemerized a whole pantheon of gods and goddesses, and from whom Phidias had immortalized the Olympian Jupiter and Athena Promachos, could have no other descendants but those they actually have — the Virgin and Saint worshipping Hellenes.

Thus we may believe that the form of worship depends more on the respective idiosyncrasies of races than on their powers of reasoning; and that the natural sympathies or antipathies of the forefathers will always be reflected more or less in the future generations. For it is but names and forms that change, ideas remain the same; and the older a faith, the stronger it clings to the relics of its youth.
