Regarding
the opinion of the Rambam that there are no demons
- This is ridicules, in many places the
Rambam himself refers to demons.
- All he said was that there is a certain breed of high power full demons
that is no longer existent.
- In ancient times people would worship these demons, channeling energy
to them through meditation and other rituals.
- When Idol worship slowed down many of them died out.
- There are plenty of lower class demons still around nowadays.
