Questionable Patterns of Change

  • Sven Ove HanssonEmail author
Part of the Trends in Logic book series (TREN, volume 46)


This chapter explores some of the problematic properties of the standard (AGM) operations of change. Both contraction and revision violate the highly plausible postulate of finite-based outcome. Contraction has further problems relating to the postulates of success, recovery, and inclusion, and revision has implausible monotonicity-related properties. Additional problems arise when the framework is extended to include conditional sentences and iterated change. The chapter concludes with a list of ten desiderata for an alternative approach to belief change that eschews the major problems exhibited in this and the previous chapter.
