From a reader:
This may or may not be of interest to you, but it did make me think of you so I thought I'd send it:
It is a new perspective by psychiatrist Iain McGilchrist on the significance of the anatomical division of the brain (i.e. left vs right hemisphere). He does not make reference to sociopathic behaviour but it would be difficult not to make some associations.
It struck a chord with me as I have always found the existence of sociopaths profoundly disembodied, ie living in their heads, in a concrete, abstract, explicit, decontextualised and heavily simplified world.
You might find it interesting.
