This collection gathers a set of provocative essays that sketch innovative and interdisciplinary approaches to Genre Theory in the 21st century. Focusing on the interaction between tragedy and comedy, both renowned and emerging scholarly and creative voices from philosophy, theater, literature, and cultural studies come together to engage in dialogues that reconfigure genre as social, communal, and affective. In revisiting the challenges to aesthetic categorization over the course of the 20th century, this volume proposes a shift away from the prescriptive and hierarchical reading of genre to its crucial function in shaping thought and enabling shared experience and communication. In doing so, the various essays acknowledge the diverse contexts within which genre needs to be thought afresh: media studies, rhetoric, politics, performance, and philosophy.
