I know it's a first draft, but "Better Angels of Our Nature", much as I love the idea of being able to geometrize moral stature.

More a text dump than anything else. Thank you for pointing out the typo thought.

I don't know what you mean by violence having some good traits.

Violence can be fun. I'd argue this is particularly true of "safe violence", that doesn't result in death or permanent injury. Otherwise we wouldn't include it so much in every aspect of entertainment, particularly interactive entertainment. We also have people who enjoy violence in their sexual lives.

I can imagine an improved society which permits low-level interpersonal violence with a strong norm that equivalent retaliation should be possible. I don't think there's anything gained by big wars, but I could be wrong.

Yes this is what I was going for.
