A world-class physicist makes a shocking claim: across 2,500 years and every kind of society, there has been a recurring moral exception carved out just for Jews--the idea that hurting Jews is, in some sense, legitimate. Most of the time, this doesn't erupt into pogroms. Instead, it lives as a background permission: a readiness to excuse, minimize, or rationalize hurting Jews when it does occur. Listen as Russ Roberts talks with David Deutsch of Oxford University about what Deutsch calls "the Pattern": a persistent, global impulse not primarily to attack Jews, but to justify attacks on Jews--socially, politically, or physically. The stated reasons shift with the era--deicide, moneylending, "cosmopolitan elites," Zionism--but the underlying permission structure remains disturbingly constant. Unsettling, challenging, and clarifying, this conversation may change how you understand antisemitism--and the moral fault lines of our civilization.
