This paper revisits the question of whether propositions in situation semantics must be persistent [Kratzer (1989). Linguistics and Philosophy, 12, 607–653]. It shows that ignoring persistence causes empirical problems for theories which use quantification over minimal situations as a solution for donkey anaphora [Elbourne (2005). Situations and individuals. Cambridge, Mass.: MIT Press]. At the same time, modifying these theories to incorporate persistence makes them incompatible with the use of situations for contextual restriction [Kratzer (2004). Ms., University of Massachusetts].
