Well now. Maybe paganism could be considered a form of metaphysical philosophy if nothing else, which could include philosophies of religion and human nature and maybe nature itself. And I don't think many philosophies have much of a structure to them, and who is to say what enlightenment means or how you achieve it. And also the concept of monotheism headed by a male God may seem absurd to you but I'm pretty sure there are a few billion other people who would not agree. I do think it wouldn't be a bad idea for anyone to give some study to all forms and schools of philosophy. Funny thing, I recently bought a book on Tao Te Ching and am working my way through it. Gotta be honest, some of it escapes me; maybe I just ain't that bright.
