Brain -v- Mind 

The word " psychology" is the combination of two terms - study (ology) and soul (psyche), or mind. The derivation of the word from Latin gives it this clear and obvious meaning:

The study of the soul or mind.

This meaning has been altered over the years until today, this is not what the word means at all. The subject of psychology, as studied in colleges and universities, currently has very little to do with the mind, and absolutely nothing to do with the soul or spirit.

It is important to understand that words and ideas are supposed to refer to something. "The large tree in the front yard" refers to an actual thing that can be seen, touched and experienced. "The man walking his little dog last night at sunset" refers to an actual event that can be seen, observed and experienced. The realm of mind is an actual realm that can be experienced, and at one time there were words that accurately referred to this realm.
