6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / d. Counting via concepts

12154

Are 'word token' and 'word type' different sorts of countable objects, or two ways of counting? [Geach, by Perry]

9. Objects / A. Existence of Objects / 6. Nihilism about Objects

8969	We should abandon absolute identity, confining it to within some category [Geach, by Hawthorne]

9. Objects / B. Unity of Objects / 2. Substance / a. Substance

18617

Substances, unlike aggregates, can survive a change of parts [Mumford]

9. Objects / F. Identity among Objects / 3. Relative Identity

16075

Denial of absolute identity has drastic implications for logic, semantics and set theory [Wasserman on Geach]

12152

Identity is relative. One must not say things are 'the same', but 'the same A as' [Geach]

9. Objects / F. Identity among Objects / 8. Leibniz's Law

16073

Leibniz's Law is incomplete, since it includes a non-relativized identity predicate [Geach, by Wasserman]

10. Modality / B. Possibility / 3. Combinatorial possibility

18618

Maybe possibilities are recombinations of the existing elements of reality [Mumford]

18619

Combinatorial possibility has to allow all elements to be combinable, which seems unlikely [Mumford]

18620

Combinatorial possibility relies on what actually exists (even over time), but there could be more [Mumford]
