Dennis Prager has produced an excellent video entitled, "Human Nature; are we basically good?"
I submitted the following response on the Prager University website: Dennis, excellent video! I agree with you that we are not basically good. I also thought your observation about how babies are "pure narcissists" was right on the money. On the other hand, while being "pure narcissists" does not make babies morally evil, it is this pure narcissism which, when left unchecked, is at the root of all evil. When some of us say that people are born "basically bad" that is what we mean. I would even call it the "sin nature."
