The ancient poets animated all sensible objects with Gods 
or geniuses.
Calling them by names and adoring them with the 
properties of woods,
rivers, mountains, lakes, cities, nations, and whatever 
their enlarged and
numerous senses could perceive. And particulary they 
studied the genius of
each city & country, placing it under its mental deity; 
till a system was
formed, which some took advantage of,& enslav'd the 
vulgar by attempting
to realize or abstract the mental deities from their 
objects: thus began
priesthood; choosing forms of worship from poetic tales. 
And it length
they pronounc'd that the gods had order'd such things. 
Thus men forgot
that all deities reside in the human breast.
