This book is about ways to understand masculinity as systemic and corporeal, structural and performative all at once. It argues that the tension between an understanding of “masculinity” in the singular and “masculinities” in the plural poses a problem that can better be understood in relation to a concomitant tension: between systems on the one hand, and bodies on the other - between abstract structures such as patriarchy, kinship or even language, and the various concrete forms taken by gendered, individuated corporeality.
