Philosopher George Santayana wrote those words 100 years ago, between two massively destructive world wars. Unfortunately, they continue to ring true today amidst a growing global epidemic of political and civil conflict. That epidemic takes many different forms—wars between countries, civil wars, brutally violent conflicts among armed gangs, large-scale terrorism, government-sanctioned ethnic cleansing—but the terrible consequences for civilians are the same. And, more and more people in more and more places are caught up in extreme violence.

What happened to the “peace dividend” after the end of the Cold War? Or the optimism of scholars like Steven Pinker and Yuval Noah Harari who expected mankind’s “better angels” to produce peace and prosperity? Did the Age of Aquarius already come and go?
