The theme for season 5 is gender and sexuality in Islam. In our first episode we provide the framework for understanding gender, sex, and sexuality in the Islamic world. We discuss three influences on the framework: cultural beliefs, the Qur'an, and the philosophical tradition of the high Abbasid period. We discuss how Muhammad strove to reform Arabian tribal society and the ways in which the Qu'ran reflects this mission as well as codifies certain social differences and structures. We talk about the vast cultural variations and how the process of Islamizing a region included adopting some cultural norms. We then discuss the Hellenic concept of the humors and their adoption into Islam and relation to understanding gender and sexuality. Finally we bring it all together to help us understand the way in which Islam views gender, sex, and sexuality on a fluid spectrum that allows for variation. This episode sets up the framework for our future conversations.
