JOHN HORGAN – Fisticuffs have broken out in The Guardian between two intellectual big shots, philosopher John Gray and psychologist Steven Pinker. The fight, which features lots of rhetorical flourishes and high dudgeon, addresses a serious issue: Is humanity achieving moral progress? Or, as Gray would put it, “progress”? More specifically, are we becoming less violent? I’ve written about this question myself, so in this post I’ll try to adjudicate the dispute, indicating what each scholar gets right and wrong.
