I this (hybrid) course we will discuss recent and not so recent approaches to semantic content that make use of the notion of a situation rather than a possible world (Situation Semantics, Truthmaker Semantics, and related views). We will discuss in particular depth the fine structure of situations: what distinguishes situations from events (and tropes), how should one conceive of part-whole relations involving situations, how should one conceive of the role of objects in situations, etc. We will discuss new empirical data bearing on the topic and develop semantic analyses for them, such as 'instead'-constructions.
