The End of Faith

"These events should strike us like psychological experiments run amok, for that is what they are. Give people divergent, irreconcilable, and untestable notions about what happens after death, and then oblige them to live together with limited resources. The result is just what we see: an unending cycle of murder and cease-fire. If history reveals any categorical truth, it is that an insufficient taste for evidences regularly brings out the worst in us. Add weapons of mass destruction to this diabolical clockwork, and you have found a recipe for the fall of civilization."

Sam Harris - The End of Faith
