Offering a concise yet comprehensive introduction to gender theory, this thought-provoking new book aims to make an intervention into the contemporary American paradigm of thinking gender and sexuality and offers a powerful challenge to the paradigm of social constructionism. Within each gender paradigm there are unacknowledged truths. The controversial claim of this book is that queer theory and intersectionality - and, more broadly, the social constructionist paradigm - have reached a limit. Indeed, it is possible that they are becoming regressive political gestures. However, there are possibilities of moving forward in this new area of transformation and Rousselle claims that a new logic of gender invention is opening up a new paradigm of thought. Part of the popular Routledge Focus on Mental Health series, this book will be of immense value to students and teachers who aim to understand in a basic way some of the various main paradigms, theories, and concepts within gender and sexuality studies. It will also be an important attempt to think beyond those paradigms and theories.
