Of course, and if not, then at least we have to really reconsider what "physical" means/entails, because of the existence of phenomena such as telepathy. One has to have led a surprisingly limited life, or has to have fooled themselves many times about things being "coincidences" that really couldn't have been, to be a physicalist.

Actually, the world consists of more than just the physical, but I think it might be rationalistic to assume that the non-physical aspect of it necessarily exists as "substances."

Also, I think that. whatever the non-physical is, there probably isn't a great divide, or dualism, between the physical and the non-physical.. it's probably more like gradients, where the physical is a particular kind of manifestation of whatever everything else is.
