 That's a really awesome design in the nervous system that helps us all be better people and feel good by giving up something for another. So I wouldn't want to denigrate that. But sometimes if people talk about selflessness, they don't even want you to feel good. Isn't it a good thing that our society values philanthropy in that way? So I think these are all positives, whereas somebody who worries about selflessness sees them as negatives.
