Some Americans have been haunted by the specter of Sharia law, but how many really know what it is? Surely, it’s not the caricature of religious fascism and xenophobia that some claim. On this episode of Why? Radio, we take a philosophical look at Sharia law, its tradition, variations, and the worldview it provides. Host Jack Russell Weinstein visits with Robert Gleave, professor of Arabic studies, University of Exeter.
