In this episode, we discuss the intersection between religion, reason, sound, and ethics. More specifically, we explore these ideas through an analysis of Islamic sermons in Egypt. My guest is Charles Hirschkind, who is an Associate Professor in the Department of Anthropology at the University of California, Berkeley. We will focus on his book The Ethical Soundscape: Cassette Sermons and Islamic Counterpublics (Columbia University Press, 2006).
