The document discusses the concept of identity as presented on social networking profiles like Facebook. It analyzes profiles through the lenses of Plato's theory of forms and Deleuze's concept of the simulacrum. While Plato saw true identity as transcending physical forms, Deleuze saw it as contingent and defined by difference rather than resemblance. The document argues that Facebook profiles are best understood as simulacra - masks that represent various identities rather than a single true self, and influence how users understand their own multiple natures.
