Whereas borders are constructed as unquestionably right . . . boundaries are what is right at the time, for particular people involved in a particular situation. . . . Whereas borders claim the unquestionable and rigid authority of law, boundaries have a fluidity, and openness to change; more a riverbank, less a stone canal. Borders demand respect, boundaries invite it. Borders divide desirables from undesirables, boundaries respect the diversity of desires.
