2. Reason / F. Fallacies / 7. Ad Hominem
We should always apply someone's theory of meaning to their own utterances [Liggins]
     Full Idea: We should interpret philosophers as if their own theory of the meaning of their utterances were true, whether or not we agree with that theory.
     From: David Liggins (Nihilism without Self-Contradiction [2008], 8)
     A reaction: This seems to give legitimate grounds for some sorts of ad hominem objections. It would simply be an insult to a philosopher not to believe their theories, and then apply them to what they have said. This includes semantic theories.
5. Theory of Logic / G. Quantification / 6. Plural Quantification
We normally formalise 'There are Fs' with singular quantification and predication, but this may be wrong [Liggins]
     Full Idea: It is quite standard to interpret sentences of the form 'There are Fs' using a singular quantifier and a singular predicate, but this tradition may be mistaken.
     From: David Liggins (Nihilism without Self-Contradiction [2008], 8)
     A reaction: Liggins is clearly in support of the use of plural quantification, referring to 'there are some xs such that'.
9. Objects / A. Existence of Objects / 5. Individuation / e. Individuation by kind
'Ultimate sortals' cannot explain ontological categories [Westerhoff on Wiggins]
     Full Idea: 'Ultimate sortals' are said to be non-subordinated, disjoint from one another, and uniquely paired with each object. Because of this, the ultimate sortal cannot be a satisfactory explication of the notion of an ontological category.
     From: comment on David Wiggins (Identity and Spatio-Temporal Continuity [1971], p.75) by Jan Westerhoff - Ontological Categories §26
     A reaction: My strong intuitions are that Wiggins is plain wrong, and Westerhoff gives the most promising reasons for my intuition. The simplest point is that objects can obviously belong to more than one category.
9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects
Nihilists needn't deny parts - they can just say that some of the xs are among the ys [Liggins]
     Full Idea: We can interpret '..is a part of..' as '..are among..': the xs are a part of the ys just when the xs are among the ys (though if the ys are 'one' then they would not have parts).
     From: David Liggins (Nihilism without Self-Contradiction [2008], 9)
     A reaction: The trouble is that this still leaves us with gerrymandered 'parts', in the form of xs that are scattered randomly among the ys. That's not what we mean by 'part'. No account of identity works if it leaves out coherent structure.
16. Persons / D. Continuity of the Self / 2. Mental Continuity / a. Memory is Self
If memory is the sole criterion of identity, we ought to use it for other people too [Shoemaker]
     Full Idea: If memory were the sole criterion of personal identity it would have to be the sole criterion that we use in making identity statements about persons other than ourselves.
     From: Sydney Shoemaker (Personal Identity and Memory [1959], §4)
     A reaction: From Locke's point of view, he is much less certain about the continued identity of other people, because he allows the possibility of transference of minds. Even we might reject physical identity, if a person had suffered a severe trauma.
Bodily identity is one criterion and memory another, for personal identity [Shoemaker, by PG]
     Full Idea: Bodily identity must be one of the criteria for personal identity (to establish that a rememberer was present at a past event), but memory itself must also be accepted as one of the criteria.
     From: report of Sydney Shoemaker (Personal Identity and Memory [1959], §5) by PG - Db (ideas)
     A reaction: This concerns the epistemology of personal identity, not the ontology. Someone with total amnesia would probably accept a driving licence as a criterion. Is personal identity a mental state, or a precondition which makes mental states possible?
