Write-up2 (as at 24/06/2018 16:32:10): Change
- Change is obviously the central problem that questions of identity address. Just what changes can an object undergo while remaining the same thing?
- That said, I’m not clear whether there will be much extra to say here other than what is covered under the heads of persistence4 and such like.
- Maybe just two things for now:-
- If I understand things aright, change is something that happens to substances5, and the question of identity is whether or not that substance remains the same substance after some change. Change is not relevant (or at least persistence through change isn’t relevant) under (at least) a couple of philosophical positions:-
- If we adopt a mereological6 essentialist7 position, whereby the things that exist are regions of space-time and their contents. Then, a things just is a collection of particles, and if one of these is destroyed, then so is the thing. This leads to the denial that there are any ordinary things, like chairs or animals, as they are always losing and gaining parts, and so only exist as the same thing momentarily.
- If we adopt a perdurantist8 account of persistence, the things that exist are space-time worms. A thing is not wholly present at a time, only its temporal stage is. The thing as a whole exists timelessly. Does the thing therefore change? Maybe not, but questions of persistence still apply, though maybe only pragmatically. Just what aggregate of stages are usefully described as a persisting thing? A four-dimensional naturalist might insist that exemplars of natural kinds – particularly organisms – have a greater claim to existence than arbitrary assemblages of stages.
- Another important matter is that (on many accounts) it is the rate of change that is critical. Everyone seems to agree that you cannot just swap out all the parts of a thing at the same time and claim that you have the same thing, whereas the assumption is that a thing can persist through change (pace the views in the bullet above) provided the changes occur slowly enough and piecemeal enough. After all, organisms9 replace all their parts over time (it is said) yet remain the same organism (ditto). It strikes me that there’s a degree of vagueness10 about how quickly the changes can take place without violating the persistence conditions of the object. Also, in the case of organisms, historically it has been supposed that the changes would take place naturally, but transplant surgery allows unnatural change. The transplanted organ will either by assimilated or rejected by the organism. If it is assimilated, especially if it’s hidden from view, we don’t feel any qualms about saying that is has become part of the organism, which has persisted through the change. I’m doubtful if we’d be so comfortable about the successful transplantation of visible parts, like limbs, particularly if only “accepted” by the use of immunosuppressant drugs.

- This is mostly a place-holder14.
- This is the write-up as it was when this Abstract was last output, with text as at the timestamp indicated (24/06/2018 16:32:10).
- 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.
- 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.
- 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.
- I’ve not been able to use my auto-linking technique as “change” is far too common a word for its references to be significant.
