[filed under theme 6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / e. Structuralism critique ]

Full Idea

It is to set theory that one turns for the very definition of 'structure', ...and this creates a problem of circularity if we try to impose a structuralist interpretation on set theory.

Gist of Idea

If set theory is used to define 'structure', we can't define set theory structurally

A Reaction

This seems like a nice difficulty, especially if, like Shapiro, you wade in and try to give a formal account of structures and patterns. Resnik is more circumspect and vague.


The 6 ideas from 'Review of Chihara 'Struct. Accnt of Maths''

Set theory is the standard background for modern mathematics [Burgess]
Structuralists take the name 'R' of the reals to be a variable ranging over structures, not a structure [Burgess]
If set theory is used to define 'structure', we can't define set theory structurally [Burgess]
Abstract algebra concerns relations between models, not common features of all the models [Burgess]
How can mathematical relations be either internal, or external, or intrinsic? [Burgess]
There is no one relation for the real number 2, as relations differ in different models [Burgess]
