Jonah Lehrer in Wired:
LEHRER: The title of The Self Illusion is literal. You argue that the self – this entity at the center of our personal universe – is actually just a story, a “constructed narrative.” Could you explain what you mean?
HOOD: The best stories make sense. They follow a logical path where one thing leads to another and provide the most relevant details and signposts along the way so that you get a sense of continuity and cohesion. This is what writers refer to as the narrative arc – a beginning, middle and an end. If a sequence of events does not follow a narrative, then it is incoherent and fragmented so does not have meaning. Our brains think in stories. The same is true for the self and I use a distinction that William James drew between the self as “I” and “me.” Our consciousness of the self in the here and now is the “I” and most of the time, we experience this as being an integrated and coherent individual – a bit like the character in the story. The self which we tell others about, is autobiographical or the “me” which again is a coherent account of who we think we are based on past experiences, current events and aspirations for the future.
The neuroscience supports the claim that self is constructed. For example, Michael Gazzaniga demonstrated that spilt-brain patients presented with inconsistent visual information, would readily confabulate an explanation to reconcile information unconsciously processed with information that was conscious. They would make up a story. Likewise, Oliver Sacks famously reported various patients who could confabulate accounts to make sense of their impairments. Ramachandran describes patients who are paralyzed but deny they have a problem. These are all extreme clinical cases but the same is true of normal people. We can easily spot the inconsistencies in other people’s accounts of their self but we are less able to spot our own, and when those inconsistencies are made apparent by the consequences of our actions, we make the excuse, “I wasn’t myself last night” or “It was the wine talking!” Well, wine doesn’t talk and if you were not your self, then who were you and who was being you?
