A Reaction

Thus 'the mouse is in the box', and 'the box contains the mouse'. A simple point, but important when we are trying to distinguish thought from language.


The 9 ideas from 'On Concept and Object'

There is the concept, the object falling under it, and the extension (a set, which is also an object) [Frege, by George/Velleman]
Frege mistakenly takes existence to be a property of concepts, instead of being about things [Frege, by Yablo]
It is unclear whether Frege included qualities among his abstract objects [Frege, by Hale]
Frege's 'objects' are both the referents of proper names, and what predicates are true or false of [Frege, by Dummett]
Frege felt that meanings must be public, so they are abstractions rather than mental entities [Frege, by Putnam]
As I understand it, a concept is the meaning of a grammatical predicate [Frege]
For all the multiplicity of languages, mankind has a common stock of thoughts [Frege]
A thought can be split in many ways, so that different parts appear as subject or predicate [Frege]
Frege equated the concepts under which an object falls with its properties [Frege, by Dummett]
