Identity
In the book “Self Comes To Mind”, Antonio Damasio describes the Autobiographical self is not only made up of memories of events that have occurred but ones we have planned and wished to happen. As these memories replay, their substance gets reassessed and rearranged, and as a consequence, they get modified minimally or very much.
Perhaps an external, or possibly an extension of this biographical editing occurs when we construct our online identities via social.
