The 8 ideas from 'Philosophy of Mathematics'

Mathematics is the study of all possible patterns, and is thus bound to describe the world [Linnebo]
Logical truth is true in all models, so mathematical objects can't be purely logical [Linnebo]
Game Formalism has no semantics, and Term Formalism reduces the semantics [Linnebo]
The axioms of group theory are not assertions, but a definition of a structure [Linnebo]
To investigate axiomatic theories, mathematics needs its own foundational axioms [Linnebo]
Naïve set theory says any formula defines a set, and coextensive sets are identical [Linnebo]
You can't prove consistency using a weaker theory, but you can use a consistent theory [Linnebo]
In classical semantics singular terms refer, and quantifiers range over domains [Linnebo]
