title: Prolegomena to any future mereology of the body.
abstract: Many bioethical arguments rely implicitly on the assumption that the concept of "human part" is one on which everyone must agree, because it is unambiguous. But various parties interpret this "unambiguous" term in incompatible ways, leading to contention. This article is an informal presentation of a topomereological system on whose preferred interpretation several distinct but related meanings of "human part" can be isolated: part of a human body, part of the completion of a human body, and part of a human being. A case is analyzed (the first total artificial heart (TAH) implantation), demonstrating in the process much of the apparatus of the system. By means of a casuistic methodology, the analysis is translated into recommendations for the ethical conduct of future TAH research. The more general conclusion, however, is that formal methods may provide useful tools for clarifying thought processes and organizing arguments in debates over bioethical issues.
