“A person’s identity is not to be found in behaviour, nor – important
though this is – in the reactions of others, but in the capacity to keep a
particular narrative going. The individual’s biography, if she is to
maintain regular interaction with others in the day-to-day world,
cannot be wholly fictive. It must continually integrate events which
occur in the external world, and sort them into the ongoing ‘story’
about the self.”
