 Conversely, as David Makinson and Peter Gärdenfors have pointed out (Makinson and Gärdenfors 1991, 185–205; Makinson 2005), an epistemological theory of belief change can be used to define a set of nonmonotonic consequence relations (one relation for each initial belief state). We can define the consequence relation \(\alpha \dproves \beta\), for a given set of beliefs \(T\), as holding just in case the result of adding belief \(\alpha\) to \(T\) would include belief in \(\beta\). However, on this approach, there would be many distinct nonmonotonic consequence relations, instead of a single perspective-independent one.
