This collection is defined as the “second wave” of masculinity theorizing. It focuses on the diversity and plurality of masculinities, the relationship between critical men's studies and feminist activism, and new interdisciplinary theoretical and methodological approaches which connect masculinities to other forms and relations of power and domination. This collection of thirteen articles is divided into two sections. The first consists of articles engaged in metatheoretical considerations for theorizing masculinities. R. W. Connell's article, “Psychoanalysis on Masculinity,” should be of particular value to those interested in psychoanalytic theory. The second section examines specific aspects of masculinities more closely.
