The default position is that there is no such thing as mind, just as there is no such thing as soul. 'Mind' is just a convenient summary of one of the functions af a human brain that we don't yet know much about. In the meantime, superstition fills the knowledge vacuum, as it always has.
The onus is therefore on those that believe that the mind is a seperate entity to the brain to show us - using more than just words - that it actually exists.

"Science adjusts it's views based on what's observed.
Faith is the denial of observation so that Belief can be preserved."
