  ==Moral responsibility== I've added several new paragraphs on what neuroscience means for our understanding of free will and moral responsibility to the end of the moral responsibility section.  It's a complex issue, and I've leaned very heavily on one paper that seems really good to me (the Greene and Cohen paper).  If anyone has time to look it over, and perhaps edit it a bit more, please feel free.  At this point, it doesn't quite flow with the rest of the section in the way that I would hope.
