The Simplicity of Everything

Part One of my dissertation is about composite objects: things with proper parts, like plates, planets, plants and people. I begin chapter 1 by pointing out that if one were to judge by the way we normally speak about composite objects, one would suppose that we were all completely certain of a theory I call folk mereology. For instance, we seem to be completely convinced that whenever some things are piled up, there is an object—a pile—which they compose. I point out that folk mereology is neither an analytic truth nor a theory for which we have conclusive empirical evidence. So what are we to make of the feeling that it makes no sense to deny folk mereology? What this shows, I claim, is that the standard which an assertion about composite objects has to meet in order to be correct is not strict and literal truth, but something less demanding. In the last part of chapter 1 and in chapter 2, I argue that we have no evidence for the existence of composite objects, and that without such evidence we ought to believe that there aren’t any composite objects. Chapter 3 is devoted to working out some details of a broadly “fictionalist” explanation of the fact that claims about composite objects can be correct without being strictly and literally true. In Part Two I defend a parallel view about complex attributes—properties, relations and propositions. In our ordinary talk about attributes, we seem to presuppose
