• Thesis Text:
  1. Identity as a logical concept is – or ought to be – rather uninteresting. Contra Wittgenstein² in the Tractatus, I consider the concept of identity to be both useful and essential.
  2. Despite much argument to the contrary, there’s only one type of identity – that which satisfies Leibniz’s Law of the Indiscernibility of Identicals and is an equivalence relation.
  3. That said, there’s a dispute going back to Joseph Butler and Thomas Reid as to whether there are two forms of identity, one allegedly falsely so-called, namely:-
     1. Strict and Philosophical, and
     2. Loose and Popular
        
  4. The idea behind this suggestions is that the conditions for the persistence of an object should be really strict – probably involving mereological³ essentialism⁴ – so that nothing ‘really’ persists through time. At the moment I’m not sure whether this suggestion is true but useless or simply false. We need the concepts of identity and persistence⁵ for all sorts of practical reasons, and a choice of concepts that never apply in the real world is no help.
  5. While rejecting them, I will still need to consider various deviant “identities” for the light they shed on the issues at hand. They are listed below. Wrong answers to tough questions can be enlightening.
  6. As for the standard notion of identity here are two “Laws” attributed to Leibniz⁶:-
     1. 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.
     2. 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).
  7. The (apparent) problems with the first₇ law are (at least) twofold:-
     1. The same object can have different properties at different times. This is the problem of temporary intrinsics⁸, and the logic of identity⁹ is tied up with resolving this issue.
     2. 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.
  8. The second Law seems reasonable enough for ordinary macroscopic objects, but
     1. 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.
     2. However, if it is false, it seems to demand haecceities¹⁰, where things are distinct just because they are distinct (something empiricists dislike).

  Further Remarks:
  1. While rejecting them, I will still need to consider various deviant “identities” for the light they shed on the issues at hand; in particular:-
     1. Contingent Identity¹¹,
     2. Indeterminate Identity¹²,
     3. Occasional Identity¹³,
     4. Partial Identity¹⁴,
     5. Relative Identity¹⁵, and
     6. Vague Identity¹⁶.
        
  2. I intend to cover the bulk of the work under the heads of the notes linked to above.

• This is the series of lectures that first engaged me with the topic of Personal Identity.

Footnote 23:

• See Section 5.8 (Stage View), paragraphs 6 & 8 for a discussion of 'loose and popular' persistence.

Footnote 25:

• Barnes alleges that the Law is due to Aristotle rather than to Leibniz.

Footnote 26:

• Modality is important in my thesis, because modal questions come into persistence criteria.
• That said, the last two essays in the book – by Hossack and Olson – are the most important, though of these two only that by Hossack really belongs to this Chapter.

Footnote 27:

• Oderberg seems to be arguing that Perdurantism is an unwanted consequence of a common-sense notion of persistence. This might therefore also be useful for perdurantism.

Footnote 28:

• Section 40 “Identity”, pp. 221-6.
