Drawing on the works of a number of postmodern theorists, this study suggests that the tattooed body is symptomatic of a general process of marking and being marked and is a social production of identity and difference. Shifting the focus away from what the tattooed body means to what it does, this work analyzes how it functions and what effects it produces. It challenges the ways in which identity and difference are discursively produced, particularly in psychological, criminological, and counter-cultural discourses. The writings of such theorists as Foucault, Levinas, Barthes, and Lingis are scrutinized to reveal how their discourse interprets the tattooed body as simply an aberrant threat to the body or simply a positive counter-cultural challenge.
