All of science is based on the idea that something for which there is no evidence probably doesn't exist. Maybe gravity is actually based on the actions of invisible fairies, but unless and until you have *evidence* of the existence of such fairies the broader scientific community is going to say you're nuts. Similarly claiming the mind has it's roots in magic/soul/etc. Unless and until you have evidence that there is something outside normal physics involved, the default assumption is that there is not. Occam's Razor is not without it's flaws, but it is extremely efficient in trimming out the vast bulk of magical thinking from the scientific community.
Physical laws are - by their very definition - non-material. Ideas like the holographic universe suggest the primacy of information over matter. We should proceed cautiously, but pure materialism seems pretty obviously wrong to me. There are even suggestions (e.g. the small variations in the gravitational constant over time) that physical laws may be "habits". I have no idea what this implies, but it suggests we should look at non-material processes.
