Drawing on the work of critical theorists such as Roland Barthes and Catherine Belsey, as well as queer theory and feminism, What the Body Cost reads against patriarchal and heteronormative tendencies in art history while providing a corrective to the established view that performance art is necessarily transgressive. Instead, Blocker suggests that the historiography of performance art is a postmodern lovers' discourse in which practitioners, historians, and critics alike fervently seek the body while doubting it can ever be found.
