Through case studies of the media art of glitch, urban explorers' use of social media, and DIY digital networks, this book then reconsiders how practice/exercise functions when the once essential bodies of the individual and a society-the two primary categories authorized by a humanist paradigm-become less reliable categories from which we might orient rhetorical action. In sum, the book argues that rhetorical practice is irreducible to the traditions and categories of humanism and must now exercise its posthuman capacities.
