This book addresses the debate within feminism and critical studies of men and masculinities on whether men should be encouraged to develop alternative masculinities, or whether they should be challenged to renounce masculinity altogether. It argues that men have to move beyond the illusion of masculinity to address their habitual ways of relating that reinforce dominance and oppression and instead foster subjectivities that are multiple and fluid. Tracing the nature of the problem associated with men, masculinity and gender, Pease examines the implications of feminist engagements with Gilles Deleuze and Felix Guattari to explore the possibilities of destabilising and moving beyond manhood and masculinity. The book will be of interest to scholars in Sociology, Psychology, Social Work and Environmental and Gender Studies, especially as they relate to critical studies of men and masculinities.
