Cases, adverbs, situations and events

In this paper we discuss two approaches to adverbial quantification, the so-called `bound variable approach' and the `situation-based approach', and we address the suggestion that has been made in the literature that the latter reduces to the former as soon as the underlying structure of situations has been characterized at the required level of detail. We will first show what constraints on situation structures are needed in order for the situation-based approach to produce the results of the bound variable approach. Then we will argue that the required constraints are at odds with the philosophy underlying the situation based approach. This result points at a principled difference between the two approaches, and this, theoretical, difference can be used as a heuristic to find empirical support for any of the two approaches.
