Write-up2 (as at 17/08/2018 21:59:02): Endurantism
- Endurantism is the traditional account of persistence, that doesn’t invoke the metaphysics of temporal parts.
- What follows is a modified version of a write-up4 of the relevant section of "Kurtz (Roxanne) - Introduction to Persistence: What’s the Problem?".
- Kurtz introduces the acronym MET for Metaphysics of Enduring Things. The contrasting acronym is MTP for the Metaphysics of Temporal Parts - that objects are said to have. These exist only instantaneously, and are otherwise known as Stages or Time-Slices. A duck – according to MTP – is wholly5 or partly constituted by temporal parts.
- Note that there are two forms of MTP – Perdurantism6 and Exdurantism7 – and (says Kurtz) their motivation8 – and that of MTP itself – comes from how well either of these accounts for persistence.
- Perdurantism and Exdurantism share a metaphysics of temporal parts, which Endurantism claims ordinary things lack. Each maintains the tension between the three non-negotiable theses9 by sacrificing at least one “intuitively and philosophically appealing” metaphysical claim on persistence. Kurtz sees this as the “real problem of persistence”.
- According to MET, at least some10 objects endure – namely, that a numerically identical object is wholly present at different times.
- For both MTP and MET, objects may have temporal parts. So, the existence of stages or a space-time worm11 is not denied by MET.
- Neither a space-time worm nor a stage is an enduring thing, as neither is wholly present at different times. Nevertheless, says Kurtz12, MET does not entail the claim that ordinary objects lack temporal parts.
- Endurantists claim that ordinary objects persist by enduring, that is, that identity over time is strict identity between objects wholly present at different times. Change is the holding of incompatible properties by objects identical over time. So far seems to be common sense13.
- To avoid the contradiction of an object having incompatible properties, endurantists adopt temporally mediated property instantiation, whereby temporal facts (whether of time or tense) external to the object mediate the instantiation of incompatible properties without an appeal to temporal parts. Thus, an ordinary object persists through change and both alters and survives. What has to be given up is the “just having” of properties. The question seems to be how important the having of properties only mediated by internal facts is.
- There are various implementations of endurantism. Those in "Haslanger (Sally) & Kurtz (Roxanne), Eds. - Persistence : Contemporary Readings" are14:-
- Kurtz thinks that the introduction of time or tense into property instantiation creates four potential problems15:-
- She thinks it irrelevant what the time is to whether an object has an intrinsic property or not.
- Issues like Bradley’s Regress (to be discussed under the head of Temporary Intrinsics16) threaten our understanding of how a property can be predicated of an object at all.
- Indexing properties to times makes them seem like different17 properties, and so gets rid of the prima facie problem of inconsistent properties too easily.
- Given the definition of change, then if the properties aren’t incompatible, why do we have change at all?

- This is mostly a place-holder23.
- This is the write-up as it was when this Abstract was last output, with text as at the timestamp indicated (17/08/2018 21:59:02).
- Link to Latest Write-Up Note.
- A number of my philosophical Notes are “promissory notes” currently only listing the books and papers (if any) I possess on the topic concerned.
- I’ve decided to add some text – whether by way of motivation, or something more substantive – for all these identified topics related to my Thesis.
- As I want to do this fairly quickly, the text may be confused or show surprising ignorance.
- The reader (if such exists) will have to bear with me, and display the principle of charity while this footnote exists.
- It seems odd to think of a duck as being wholly constituted by a single temporal part, but this just is the exdurantist claim.
Footnote 9: These are:-
- I had thought the motivation came from the need to explain conundrums like Fission, but it seems there are philosophical difficulties with MET (the problem of Temporary Intrinsics).
- Consistency: the same thing cannot have incompatible properties. Follows either from the law of non-contradiction or from Leibniz’s Law.
- Change: Change involves incompatible properties.
- Persistence: Objects persist through change.
- This sounds like an existence-claim, but we let it pass.
- Though the worm is not an “ordinary thing”, but (presumably) a collection of momentary stages, which are themselves not ordinary things.
Footnote 13: I need to put the following footnote somewhere, so here goes: Footnote 14:
- This sounds wrong as far as ordinary objects are concerned – I need to check what the endurantists say on this.
- Presumably, these chapters present, but don’t necessarily support, endurantism.
- Presumably for MET only. I’m not hugely convinced by these – and Kurtz admits she’s only gestured at them to get them on the table.
- And, if they are different properties it (to my mind) obscures what makes Red-at-T1 and Red-at-T2 both instances of Red.
- If only a “non-updating” run has been made, the links are only one-way – ie. from the page of links to the objects that reference this Note by mentioning the appropriate key-word(s). The links are also only indicative, as they haven’t yet been confirmed as relevant.
- Once an updating run has been made, links are both ways, and links from this Notes page (from the “Authors, Books & Papers Citing this Note” and “Summary of Note Links to this Page” sections) are to the “point of link” within the page rather than to the page generically. Links from the “links page” remain generic.
- There are two sorts of updating runs – for Notes and other Objects. The reason for this is that Notes are archived, and too many archived versions would be created if this process were repeatedly run.
- Frequently I’ll have made copious marginal annotations, and sometimes have written up a review-note.
- In the former case, I intend to transfer the annotations into electronic form as soon as I can find the time.
- In the latter case, I will have remarked on the fact against the citation, and will integrate the comments into this Note in due course.
- My intention is to incorporate into these Notes comments on material I’ve already read rather than engage with unread material at this stage.
Footnote 21: Footnote 22:
- I may have read others in between updates of this Note – in which case they will be marked as such in the “References and Reading List” below.
- Papers or Books partially read have a rough %age based on the time spent versus the time expected.
