The "reality" of the mind is that it is separate from the material brain, and thus cannot be quantified by science and never will. A human spirit or soul if you will, is NOT subject to being bottled up in a jar -- unless you think it possible?
It is only human arrogance that demands everything be "proven" scientifically in a lab or else it is invalid.
The mind is a process that is carried out by a material brain. Science can come to understand processes, at least in general terms. We understand weather, for instance, but actual weather systems are complex beyond absolute knowledge of all details. Therefore weather forecasting depends upon simplified models.
The brain is likewise very complex and concepts like understanding "self-awareness" are not yet in hand -- if ever. But just because things are complex, like the weather, doesn't mean we have to assert a weather god.
It is only human ignorance that demands everything be wrapped up in a nice little box by their god and their bible or else it is invalid.
