This book brings together the emerging insights of what posthumanism, new materialism and affect theory mean for 'the man question'. The contributors to this book interrogate the question of how 'Man' as a gendered being is entangled with nature, culture, materiality and corporeality, and they explore ways to unsettle men's sense of sovereignty to decentre anthropocentric masculinity. Men have to move from the centre of privilege which grants them supremacy before they can open themselves to the decentred, embodied, affective, vulnerable and relational self that is necessary to embrace the posthuman. This book explores the extent to which this is possible. The book will be of interest to academics, students and scholars across a range of disciplines who are engaging with the intersections of feminist studies with posthumanism and new materialism, especially as they relate to critical studies of men and masculinities. Chapters on fathering, pornography, ageing, affect, embodiment, entanglements with technology and nature and the implications of these issues for changing men and masculinities and the politics of critical masculinity studies' engagement with posthuman feminisms will interest students and academics across these diverse disciplines. © 2023 selection and editorial matter, Ulf Mellström and Bob Pease.
