Each of us not only 'has', but lives a biography reflexively organised in terms of flows of social and psychological information about possible ways of life. Modernity is a post-traditional order,
in which the question, 'How shall I live?' has to be answered in day-to-day decisions about how to behave, what to wear and what to eat - and many other things - as well as interpreted within the temporal unfolding of self-identity.
