The 8 ideas from 'Intro to 'The Reason's Proper Study''

The neo-Fregean is more optimistic than Frege about contextual definitions of numbers [Hale/Wright]
The incompletability of formal arithmetic reveals that logic also cannot be completely characterized [Hale/Wright]
Objects just are what singular terms refer to [Hale/Wright]
Abstracted objects are not mental creations, but depend on equivalence between given entities [Hale/Wright]
Many conceptual truths ('yellow is extended') are not analytic, as derived from logic and definitions [Hale/Wright]
If 'x is heterological' iff it does not apply to itself, then 'heterological' is heterological if it isn't heterological [Hale/Wright]
If structures are relative, this undermines truth-value and objectivity [Hale/Wright]
The structural view of numbers doesn't fit their usage outside arithmetical contexts [Hale/Wright]
