Simon Baron-Cohen, who I have mentioned before in conjunction with autism research, has banishing evil and increasing empathy as his new project. Hard to argue with the spirit of that, but it would seem at minimum quixotic.
He has some thought of redefining evil as lack of empathy, and seeking ways this might be treated. He's an intelligent man, and the immediate objections that come to mind have likely occurred to him, at least in part, so I don't want to shoot from the hip and reveal my dilettante shallowness. Yet it does occur to me that this is exactly the sort of grandiose scheme that gets humankind in trouble. The balance of empathy along a continuum in a tribe might allow only a narrow range for group survival.
For the record, yes, he is related to Sasha Baron-Cohen of "Borat" fame. There are other filmmakers and artists in the family tree as well. And yes, the irony of a premiere social-understanding researcher being Borat's cousin is worth contemplating.
