I was thinking today about Objectivist/ish conceptions of mind, volition and 'determinism.' The context is a 2014 book called "The Psychopath Whisperer." I am about half-way through giving it a thorough read, and want to recommend it to OLers interested in the intersection of law, punishment, philosophy and neuroscience.
Of interest to those who consider psychology a fatally-soft science or a fledgling, the book's central question is "Are there structural/developmental 'indicators' in brains of psychopaths?" or "Are brains of a psychopath different from non-psychopaths?"
The premise is that psychopaths are indeed 'different from you and me,' and that the brain is the seat of behaviour.
The author, Kent Kiehl, is a bit of an obsessive on the subject of psychopathy. This drive to understand the brain/mind of a psychopath led him to pioneer brain-imaging (fMRI) in prisoners with psychopathy, the worst of the worst offenders -- and to synthesize what he has learned at this point in his research career.
For those of you who would like a link or two, here is the book's page at Amazon (with reviews), and here are some links to explore ... (snatched from the jaws of Google)
