5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic
Logicians like their entities to exhibit a maximum degree of purity
5. Theory of Logic / F. Referring in Logic / 2. Descriptions / c. Theory of definite descriptions
For Russell, expressions dependent on contingent circumstances must be eliminated
9. Objects / C. Structure of Objects / 7. Substratum
Models nicely separate particulars from their clothing, and logicians often accept that metaphysically
10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity
The simplest solution to transworld identification is to adopt bare particulars
10. Modality / E. Possible worlds / 3. Transworld Objects / c. Counterparts
Essence is a transworld heir line, rather than a collection of properties
Unusual people may have no counterparts, or several
10. Modality / E. Possible worlds / 3. Transworld Objects / d. Haecceitism
'Haecceitism' is common thisness under dissimilarity, or distinct thisnesses under resemblance
'Haecceitism' says that sameness or difference of individuals is independent of appearances
If quantification into modal contexts is legitimate, that seems to imply some form of haecceitism
19. Language / A. Nature of Meaning / 8. Synonymy
Sentences might have the same sense when logically equivalent - or never have the same sense
19. Language / B. Reference / 3. Direct Reference / b. Causal reference
Are causal descriptions part of the causal theory of reference, or are they just metasemantic? [Schaffer,J]
19. Language / C. Assigning Meanings / 10. Two-Dimensional Semantics
Indexicals have a 'character' (the standing meaning), and a 'content' (truth-conditions for one context) [MaciÓ/Garcia-Carpentiro]
'Content' gives the standard modal profile, and 'character' gives rules for a context [Schroeter]
