I do understand what you're saying, Jim, but it's the people who suffer from Schizophrenia who don't like it when the term is used that way because it's misused so much already, regardless of what a dictionary says.  They feel stigmatized when the term is used in the way you used it.  One reason for this because the disease is so misunderstood to begin with.   

In this case, I think "schizophrenic" does a great job capturing the weird, unhealthy split thinking of premies and anyone who believes they've got not one but two conscious centres within, the mind and the heart.    

You prove my point.  The disease Schizophrenia has nothing to do with split thinking, and it's an organic disease.  The kind of thinking that we see premies present here all of the time isn't due to an organic illness, and they don't have to think that way.  Schizophrenics have no choice.  When people use the word to describe something that way, it's incorrect.  I suppose dictionaries needs to be updated to reflect this as scientists learn more about the disease. 

But, like John, I don't want to get into a long discussion about it either.
