Hospitality's vulnerability and political limits

In ancient Greece, hospitality (or xenia) was seen as a sacred moral imperative. Someone who defied the obligations placed on both host and guest risked the wrath of the gods, or even outright war. Today, the word xenia has largely fallen out of use, but its opposite, xenophobia, has been a driving factor in contemporary politics for years. IDEAS explores ancient traditions of hospitality in this second episode of our five-part series, The Idea of Home. *This episode originally aired on June 14, 2022.
