In this book, the authors engage in an interdisciplinary and multi-perspective examination of gender norms and their social conditioning. "Passing" is variably anchored, effective, and significant in the lives and actions of individuals. It reveals the continuities, boundaries, and spaces for maneuver within gender semantics. The volume raises questions about (confident) failure in this context and explores the possibilities and limits of subversion and other fields of action. The texts gathered here offer theoretical, topic-specific, analytical, and personal approaches. They point to a broad foundation for engagement, make divergences in gender theory transparent, and invite readers to actively continue the discourse.
