Full Idea
If events are classes, as I propose, then they have a mereology in the way that all classes do: the parts of a class are its subclasses.
Gist of Idea
Events are classes, and so there is a mereology of their parts

A Reaction
Lewis says events are properties, which he regards as classes. It is not clear that events are strictly mereological. Could one happening be two events? Is WWII a simple sum of its parts? [see p.260]
15561 | The events that suit semantics may not be the events that suit causation [Lewis] |
15562 | Causation is a general relation derived from instances of causal dependence [Lewis] |
15564 | An event is a property of a unique space-time region [Lewis] |
15563 | Properties are very abundant (unlike universals), and are used for semantics and higher-order variables [Lewis] |
15565 | Events have inbuilt essences, as necessary conditions for their occurrence [Lewis] |
15566 | Events are classes, and so there is a mereology of their parts [Lewis] |
15567 | Some events involve no change; they must, because causal histories involve unchanges [Lewis] |
