• Thesis Text:
  1. What follows is a modified version of a write-up² of the relevant section of "Kurtz (Roxanne) - Introduction to Persistence: What’s the Problem?".
  2. Exdurantism is otherwise known as Stage Theory and Kurtz describes it as analogous to identity between possible worlds. Just as an object might have had incompatible properties – and this is cashed out as a counterpart in a possible world having these properties – so a temporal counterpart stage of the object has them. The objects with incompatible properties are, in both cases, non-identical counterparts of one another. So, the exdurantist then contends that change over time is nothing more than an object and its temporal counterpart having incompatible properties and existing at different moments in the actual world.
  3. Exdurantists have it that an object is numerically identical to a single stage, and is wholly present at the moment it exists. In contrast to Perdurance³, according to Exdurantists, objects persist when they exdure, and exdure by changing over time. An object changes over time, then, when it and a counterpart stage just have incompatible properties. Consequently, an exduring object does not – strictly speaking – survive change⁴.
  4. Just Having (a property) is a term of art. To quote Kurtz: an object just has a property⁵ if and only if no extrinsic facts are relevant to the truth of the proposition that the object has that property. It is a slightly tricky concept, and "Lewis (David) - Rearrangement of Particles: Reply to Lowe" is invoked, which refers to non-relational changes (the example is of changing your shape by sitting, etc.).
  5. The primary proponents of Exdurance are Ted Sider and Katherine Hawley.
  6. Acording to Exdurance, an object undergoes change⁶ when it and a counterpart “just have” incompatible properties. It persists⁷ when it changes over time by standing in the counterpart relation to a stage from a different time. As no single thing has incompatible properties (different stages are different objects), Exdurantism satisfies the demands of consistency. Just how is this “Counterpart Relation” cashed out?
  7. Exdurantism has the advantage over Perdurantism⁸ in that it’s the object itself that “just has” its properties⁹, rather than a (temporal) part of the object. However, just like Perdurantism¹⁰, Exdurantism rules out change¹¹ as is commonly understood. In both cases, it’s just different stages that have the incompatible property, not one and the same whole object.
  8. But, Exdurantism does much worse over survival, in that an exduring object doesn’t survive¹², as the different stages are different objects. At best, an exduring object “continues¹³,¹⁴” in some way, but the momentary stages are no more identical than are links in a chain.
