Abstract
I explicate and defend a non-standard theory of persistence, which I calltransdurantism. In short, transdurantism is the view is that objects persist by being temporally extended simples. Transdurantism is sometime misrepresented as a version of endurantism. Other times, transdurantism is misrepresented as a version of perdurantism. But I argue transdurantism must be disambiguated from perdurantism and endurantism—when endurantism, perdurantism, and transdurantism are properly construed, transdurantism stands apart from the other theories of persistence and we can better understand the distinct burdens they each bear. I also argue that the transdurantist is capable of handling several key problems found in the persistence literature at least as well as her rivals, but she does face her own unique challenges.
