The belief in spirits and demons is called either "spiritualism" or "religion".
Demons and Spirits exist as do Angels.
no. Demons and evil spirits do not exist.
There are as many viewpoints regarding spirits and demons as there are Pagans in the world. Some may believe in them, other may not, and within those beliefs there may be many strands of understanding. Tribal cultures with strong remnants of animist belief often incorporate work with spirits and demons into their everyday lives, while many western neo-pagans may concentrate instead on celebrating the changes in the agricultural seasons and never consider such things as spirits.
