I’m currently reading (very slowly) Steven Pinker’s magisterial The Better Angels of Our Nature. It’s a history of violence in human societies, and his thesis is that violence has actually declined over the centuries. It seems difficult to believe, but Pinker marshals his facts and presents a convincing case.
And on the theme of the distressing fact that violence and humanity are inextricably locked together, here’s Nina Paley’s offering on that theme.
More about the film, Seder Masochism, together with a handy guide to who’s killing who, can be found on Nina’s Blog.
