The brain is a material object which has many functions and is subject to change in structure and ability to function.
Perhaps the word “feelings” would convey the problem better.
The mind is a function of the “rational” soul of humans and should guide action by reasoning.
Perhaps word like “reason” would be more descriptive.
Any Freeper???
Because the brain represents the body and the mind represents the soul or spirit. It is the extra dimensionality of human thought process understood by Hebrew vs greek philosophy showing.
