This chapter discusses some relations of new materialism (NM) and Critical Studies on Men and Masculinities (CSMM), and the material-discursive spaces that are thus opened up for further critical inquiry. While highly varied, NM is characterized here by the extension of relationality as an umbrella term incorporating intersections, interactions, intra-actions, interconnections, assemblages, and decentring the human and working on the more-than-human. These relationalities, themselves interconnected, include the relationalities of the matter of: spatiality and the planet; bodies and nature; things and technologies; and knowledge. These four relationalities are interrogated through looking back at some personal biographical influences and broader developments in CSMM, as well as through looking forward to possible implications of NM for CSMM and its possible demise.
