@deepthot,
Thank you for the response
Of what I have read so far, which is not much beyond RL's first link,
what I find most the most value in is this:
Demonstrating a way in which by starting at a value of strictly (self interest), the other values of (interests outside the self) can be derived.
In a sense, reasoning from sociopathy to empathy.
This reasoning will (I think) hinge upon the strength of the psychological evidence regarding the outcomes, looked at from a self-interested perspective.
In other words answering whether being empathetic is more or less valuable than being sociopathic (from the perspective of a highly reasoned sociopath).
My arm-chair analysis is that, there is some strong psychological evidence that empathy
is an effective strategy for a sociopath.
Thanks again.
