Inspiring but not fluffy. Bregman brings the FACTS, often debunking the previously unexamined version of well known stories and studies that bolster cynicism/negative view of humanity. He also explores some of the darkest moments in history to tease out the factors at play/how those could have occurred if we're to take a more hopeful view of humanity. I appreciated the 'new realism': positive change can occur, there's proof it's happened before.
