摘要: Since a human mind cannot deal directly with infinite structures, cognitively realistic models of belief change should operate on belief states that have a finite representation. The standard AGM model cannot easily be reconciled with that requirement. Different ways to achieve a finite representation are discussed, in particular: finite language, belief bases, and specified meet contraction. Formal results that compare and connect the different approaches are presented.
