This is a study of events and their place in our language and thought. The author discusses what kind of item an event is, how the language of events works and how these two themes are interrelated. He argues that most of the supposedly metaphysical literature on events is really about semantics of their names, and that the true metaphysic of events - known by Leibniz and rediscovered by Jaegwon Kim - has not been universally accepted because it has been obscured by a false semantic theory.
