Andy Clark and David Chalmers (1998) in their seminal work on ‘Extended Cognition’ or ‘Extended Mind’, demonstrated a fictional character, Otto, who has a notebook. For the notebook to be functionally identical to Otto’s memory it has to be available to him automatically, involuntarily, and reliably. However, it has been argued that as the notebook does not have these features it cannot be a part of Otto’s mind. I disagree with this claim that for a notebook to be functionally identical to one’s memory, it should be automatically, reliably and involuntarily available to him.
