Abraham Joshua Heschel was a Polish-born American rabbi, theologian, and civil rights and anti-war leader. To this day, Heschel remains a symbol of the fight to make progressive Jewish values relevant in the secular world. Julian Zelizer wrote a biography on Heschel's life from childhood to death, detailing his position at the intersection of religion and progressive politics in mid-20th-century America.

Sam Wang interviews Julian about the new book in this week's episode.
