Write-up2 (as at 23/09/2020 10:39:22): Duplication
- Duplicate objects are – to use the definition in "Sider (Ted) - Naturalness, Intrinsicality, and Duplication" – “exactly similar, considered as they are in themselves”. That said, it misses off the question “which is the original?”. A “duplicate” is – by implication – a copy of the original. I don’t think there’s the same implication in the term “double”, though saying that person X is person Y’s “double” – while it doesn’t imply precedence of one over the other – doesn’t even imply exact similarlity4 – just that “identity” might be mistaken (and maybe not even that, quite).
- There is considerable overlap between this topic and two other topics:-
→ Replication5, which is really the same thing (though not restricted to a mere doubling), and
→ Reduplication Objections6
- The motivation for this Note – and those above – comes mainly from the above (Re-)duplication objections – where some putative change appears to preserve identity, but cannot for logical reasons, as explained in that Note.
- If I accept Lewis’s perdurantist7 thesis, the straightforward objection to the identification of the duplicate with the original is undermined – they simply share stages. However, there are still causal chain8 problems to address, and those of physical continuity9.
- While cloning10 falls under this head, there is no identity11 preservation, even under a perdurantist12 thesis, as there are no shared stages, just shared genetic material.

- Works on this topic that I’ve actually read14 include the following:-
- "Noonan (Harold) - The Reduplication Problem"
- A further reading list might start with:-
- "Sidelle (Alan) - Finding an Intrinsic Account of Identity: What is the Source of Duplication Cases?"
- "Sider (Ted) - Naturalness, Intrinsicality, and Duplication"
- This is mostly a place-holder15.
- This is the write-up as it was when this Abstract was last output, with text as at the timestamp indicated (23/09/2020 10:39:22).
