The times we live in are alternately derided for their failings and romanticized for their emerging opportunities. It sometimes seems that we now live amid greater violence, greater uncertainty; that the world suffers more conflicts and tragedies; that the poor are poorer and greater in number; that race, ethnicity and nationalism divide us more intractably than ever before. But that is not so. Human beings are still capable of violence and cruelty. We all succumb to sin. But look back at any preceding century or even just a few decades, and you will see cruelty, violence and misery on a scale that is, with few exceptions, unknown today.
