The word occult is a human-made word to which right-wing Christians give a highly negative connnotation.
It's so easy to slander and dismiss and demonize these old authors who were erudite truth-seekers. They're dead, so their words can be twisted and they have no way to defend themselves.
If you you haven't even read an author's works, how do you know they're so evil?
I guess we'll find out the truth when we get to the other side.
