Because Mailer often addressed various modes of violence in his fiction and nonfiction, over time many readers have mistakenly believed that Mailer endorsed all forms violence. Yet Mailer was careful to parse the nuances of different forms of violence, and rarely, if ever, does violence go wholly unquestioned in his work. This chapter covers Mailer’s distinctive criticisms of violence, addressing his notions of “creative” violence versus purely destructive violence; his sharp criticisms of the violences enacted in Vietnam; his meditations on structural violence, and the connections he draws between violence, courage, and manhood.
