Mind and matter part of the metaphysics sounds fishy to me. I don't know much about it at all. It just sounds fishy.
Maybe it depends on how you approach the subject. If you approach it from an abstract/artist point of view it may be onto something about helping develop intelligence. But if you create religions, that may have the opposite effect of under developing intelligence, as it takes away other peoples ability to imagine/think for themselves, instead they will cling to something someone else imagined.
But at the end, only empiricism can prove something for realz.
