Write-up2 (as at 17/08/2018 17:35:31): Leibniz
- I’m uncertain whether this Note will cover anything apart from Leibniz’s Law(s).
- However, Leibniz’s critique of Locke in "Leibniz (Gottfried), Remnant (Peter), Bennett (Jonathan) - New Essays on Human Understanding" may be worth following up, though I suspect life’s too short.
- There are two “Laws” attributed to Leibniz:-
- The Law of the Indiscernibility of Identicals: this just appears to be a law of logic, and is (almost) universally accepted. It states that if “two” objects are identical (that is, “they” are the same object picked out by two descriptions) then “they” have exactly the same properties – both intrinsic and relational.
- The Law of the Identity of Indiscernibles: this is a more contentious – and metaphysical – suggestion, and is that if “two” objects share all the same intrinsic and relational properties, they are identical (ie there is only one object, but picked out by different descriptions).
- The (apparent) problems with the first4 law are (at least) twofold:-
- The same object can have different properties at different times. This is the problem of temporary intrinsics5, and the logic of identity6 is tied up with resolving this issue.
- Intensional properties are excluded from consideration – as revealed by the masked man fallacy: the fact that I don’t know that the masked man is my father – though I do know that my father is my father – doesn’t mean that the masked man isn’t my father.
- The second Law seems reasonable enough for ordinary macroscopic objects, but
- It is allegedly false for quantum objects, and could also be false in a universe consisting of two exactly similar spheres. It is neither a logical nor a necessary truth, if it is true at all.
- However, if it is false, it seems to demand haecceities7, where things are distinct just because they are distinct (something empiricists dislike).
- For a page of Links8 to this Note, Click here. Because the number of references to Leibniz – mostly irrelevant – was so large, I ran the “updating run” for “Leibniz’s Law” (and cognates) only first, and then ran again “non-updating” including “Leibniz”.

- This is a place-holder13.
- This is the write-up as it was when this Abstract was last output, with text as at the timestamp indicated (17/08/2018 17:35:31).
- 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.
- No doubt there’s a convention as to which is the “first” and which is the “second” of Leibniz’s Laws, but they are often confusingly combined into one law with two parts.
- 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.
- 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.
- The papers reviewed by Bayliss (and the review itself) are all rather old, so I’ve not selected for further study all the papers reviewed in this brief article.
- Barnes alleges that the Law is due to Aristotle rather than to Leibniz.
