title: Aristotle on Like-partedness and the Like-parted Bodies.
abstract: This paper offers an interpretation of Aristotle's treatment of the homoeomerous, or like-parted, bodies. I argue that they are liable to be far more complexly structured than is commonly supposed. While Aristotelian homoeomers have no intrinsic macrostructural properties, they are, in an important class of cases, essentially marked by the presence and absence of microstructural ones. As I show, these microstructural properties allow Aristotle to neatly demarcate the non-elemental homoeomers from the elements. That demarcation, in turn, helps to clarify Aristotle's conceptions of both homoeomery and what it is to be a bodily element. On Aristotle's account, I argue, a homoeomerous body, as such, is divisible into at least one part that is the same specific kind as the whole. Elemental bodies are the limiting case. For Aristotle, an elemental body is only divisible into parts that are of the same specific kind as the whole.
