Their worship was not paid to the demon which such a being as they imagined would really be, but to their own idea of excellence. The evil is, that such a belief keeps the ideal wretchedly low; and opposes the most obstinate resistance to all thought which has a tendency to raise it higher. Believers shrink from every train of ideas which would lead the mind to a clear conception and an elevated standard of excellence, because they feel (even when they do not distinctly see) that such a standard would conflict with many of the dispensations of nature, and with much of what they are accustomed to consider as the Christian creed.
