 There is currently no consensus about the semantics of attitude ascriptions, and it is not clear whether situation semantics has a privileged place in the family of accounts that have been proposed. Perhaps more importantly, for most empirical generalizations in linguistic semantics, propositions construed as sets of possible worlds or situations provide the right level of abstraction. There seems to be no need to posit unwieldy information contents in areas where simpler notions provide more elegant accounts. Since this article is not about theories of information, the concern to provide a general theory of information content will now have to be set aside, even though it is central to some areas in situation semantics and situation theory (Devlin 1991, 2006; Ginzburg and Sag 2000; see also Barwise &amp; Seligman 1997). The remainder of this article will review situation-based accounts of selected topics that are currently under active investigation in linguistics and philosophy: Austinian topic situations, domain restrictions, donkey sentences, exhaustive interpretations, and Davidsonian event predication. None of those phenomena requires a more fine-grained notion of information content. The discussion will thus be cast within a possibilistic framework (Kratzer 1989, 2002, 2012; Elbourne 2005, 2013). Possibilistic versions of situation semantics are conservative extensions of possible worlds semantics that construe propositions as sets of world parts, rather than complete possible worlds (see Barwise 1988, chapter 11, for an overview of the major branch points in situation semantics). There are many areas that situation semantics has contributed to that could not be reviewed here for reasons of space, including knowledge ascriptions, questions, discourse relations, counterfactuals, viewpoint aspect, gerunds, and implicit arguments. Stojanovich 2012 and Zucchi 2015 are recent general overviews of situation semantics. Additional references to work on various phenomena within a situation-based semantics are given below under the heading references not mentioned in the text.
