Self-plagiarizing another account of just how dark rationalists can become in their ‘solutions’:

I witnessed an event some years ago at my university that sent chills down my spine. This event was similar to the Libet story in being that of a well-known scientist presenting a dénouement of our moral and ethical agency. It was during a talk by Patricia Churchland, a “neuro-philosopher” as she calls herself, that she gave at Stony Brook University (State University of New York) in February 2008. Her argument was to the effect that individuals with a body-chemistry associated—by neuroscientists—with violent or destructive behavior should be separated from the rest of society before they harmed themselves or others, or gave any indication that they were inclined to do so, since their body-chemistry effectively determined that they would do so at some point.

This included, she said, infants at birth who tested positive for the “violent or destructive behavior body-chemistry,” who should be separated from their parents and raised institutionally, because they were destined to be violent or destructive!

What was on display in her talk was the mereological reduction of the potential actions of a class of human beings to the chemical “makeup” of their bodies.

And she wasn’t laughed out of the auditorium! She received a standing ovation from many of the scholars in the audience.
