Izzy Posen grew up in London's Hasidic Jewish community in Stamford Hill, receiving the bare minimum of secular education in an illegal school which still practiced corporal punishment. Even with the strictures of this insular community, he developed an acute curiosity about the world, resulting in him teaching himself English and eventually leaving the community to study physics and philosophy. Ash talks to Izzy about the history of this religious enclave, whether the state should interfere with child rearing and the correct way to cut your nails in the eyes of the Lord.
