Heidegger: Facebook promotes authenticity by offering people the chance to assume responsibility over their identity and realise that they are in a ‘self-making-situation’.
Sartre: Facebook promotes authenticity by revealing that there is in fact a lack of identity when presenting a self due to the fact that one always has the freedom to choose to move beyond their current situation
Lyotard: Facebook promotes inauthenticity because individuals are no longer concerned with developing a sense of personal identity that is a true representation of them but only with developing an identity that will perform well within their social network in order to increase their social capital
Foucault: Facebook promotes inauthenticity because people are not concerned with developing an identity that is a true representation of them but only with conforming to a certain ideal of how a person ought to be in order to be accepted and not excluded by their social network
