The book that I've been working on involves a lot of magic, which ties in to how the world works. I've studied a lot of occultism from the Renaissance and early nineteen hundreds, mostly because I wanted the magic to be like old myths. One of the main philosophies I used (to an extent) is Mentalism, which comes from Hermeticism. Essentially, it's the belief that the whole universe (including people) are part of a celestial mind, and that thoughts create reality. This is what allows for magic to be possible. My magic system isn't entirely like that, but it has a lot in common with it (along with a lot of other traditions from around the world that I've studied). However, in real life, I'm most definitely an atheist (I don't know if that's better or worse to religious fundamentalists than being an occultist). I find the theories that I've incorporated in my writing ludicrous, and even harmful when applied to real life (all of the third world countries that are plagued with superstition). I know it's fiction, but there are messages/morals that I want to get across with my writing. Would basing my world around a philosophy I disagree be harmful to that, or do you think I'm overreacting?
