JERUSALEM LECTURES In 1992, I was a Lady Davis Fellow in the English Department at the Hebrew Univer sity of Jerusalem. In the context of this, Edit Doron asked me to present a series of weekly evening lectures. The idea was that I would be talking about my own current research on plurality in an event based theory, without the restraints that a nonnal seminar fonnat would im pose: i.e. the idea was that I would actually get to the part where I would talk about my own work. At the same time, Edit added, it would be nice if, rather than just presupposing or presenting a neo-Davidsonian framework to develop my analysis of plurality, I could provide a more general setting of the problems by discussing in some depth the archi tecture of event arguments and thematic roles. In particular, Terry Parsons' book, Par sons 1990, had appeared relatively recently, and there was real interest among the audience in discussing Parsons' arguments for events and roles.
