I am not talking about faith. I am talking about what happens when an individual perceives. There's no faith about that. Like many things accpeted on the basis of probable rightness it is not ultimately disprovable for a number of reasons, one being the extraordinary capacity of the mind for plasticity and self-imposed blanking of non-conforming data. The notion that something that is not material MUST be taken on faith ignores a great deal of experiential evidence from every region where humans strive to live.
