Amid stories of horrific atrocities like the Holocaust and the ethnic cleansing that took place in the Balkans in the 1990’s, occasional tales of courage emerge: the stories of individuals who fly in the face of convention – or even the law – to stand up for what they know is right. In his new book, Beautiful Souls: Saying No, Breaking Ranks, and Heeding the Voice of Conscience in Dark Times, Eyal Press explores the flip side of evil, telling dramatic stories of dissent through the lens of the emerging fields of moral psychology and neuro-science. The result is a book that not only fleshes out stories of stunning bravery, but digs into the “why” of acts that seem impossible in their contexts.
