I'm a fan of Steven Pinker and particularly The Better Angels of Our Nature. That's absolutely right - we live in the most peaceful times ever. Thank you for writing this - it's always an important reminder.
PS: I wrote about this very topic 10 months ago! And again 7 months ago. Oh, how time flies :)
ya his work is awesome, he's a very clear thinker and good communicator
hope you don't mind me going over the same ground you've already covered
This ground was covered by Steven Pinker first, and I say keep writing about it! It's an important topic that should get as much attention as the doom saying media. Of course, it's much more than just violence - the world is improving in pretty much every way (except for the environment).
