This paper explores how self-identity can be impacted upon by the use of digital and social media. In particular, drawing on a narrative account of selfhood, it argues that some forms of activity and interaction on the internet can support the capacity to be oneself, and foster transformative processes that are self-enhancing. I start by introducing different positions in the philosophical exploration of identity online, critically outlining the arguments of those who hold a “pessimistic” and an “optimistic” stance respectively. I (...) then expand on the narrative identity framework that has been used to support the optimists’ view, arguing that digital and social media use can foster forms of self-understanding that enable us to preserve or develop our identity. More precisely, exploring these dynamics also in relation to the lived experience of mental ill-health, I maintain that internet-enabled technology can support narrative self-constitution in three main ways: (1) by facilitating the processes through which we remember self-defining life-stories; (2) by enabling us to give salience to the stories that we decide should matter the most; and (3) by providing us with opportunities to obtain social uptake for our narratives. I then conclude by dispelling some possible objections to the use of a narrative approach to account for selfhood online. (shrink)
