Yes I tend to agree with much of that and you have caused me to , once again , to think about my own moral values as I tend to be somewhat leaning towards the psychopathic end of 'the scale' when I have taken online tests to evaluate myself.
I think it should be left to the philosophers and psychologists to attempt to use science (I don't know how they would do that because they are not scientists)to come up with some conclusions on deriving morality from a particular starting point.
Until we have a ToE , in the main philosophers will continue to 'split hairs'
I think it's up to us all to use the facts to determine how we want to achieve what we want but in the end it will be what we want. Despite posting a number of articles which are philosophically based, I don't have a lit of time for academic philosophy. How we think and how we examine what we each believe is much more important. We all "do' philosophy and that doing is in the end for me the most interesting of subjects.
Don't get me wrong, I find science in all its guises fascinating and crucial to what we understand of the world but its the subjective world of desires and wants that drive us.
As an aside on our discussion of facts vs opinions, I was just reading this on the impacts of ocean acidification and I think it illustrates that often it isn't that easy to untangle fact from opinion.

I take that as a huge compliment and it's not about people changing their mind but about having better understanding and reasons. I much prefer discussions where there are not simple dichotomies but an exploration of issues. We live in a time where even getting facts seems to be harder and harder, and any truth we might cling to is almost certainly an illusion
