Single Idea 6295

[filed under theme 6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / d. Platonist structuralism ]

Full Idea

If we take mathematics at its word, there are too many mathematical objects for it to be plausible that they are all mental or physical objects.

Gist of Idea

There are too many mathematical objects for them all to be mental or physical

A Reaction

No one, of course, has ever claimed that they are, but this is a good starting point for assessing the ontology of mathematics. We are going to need 'rules', which can deduce the multitudinous mathematical objects from a small ontology.


The 12 ideas with the same theme [structuralism with real objects or real structures]:

There are too many mathematical objects for them all to be mental or physical [Resnik]
Maths is pattern recognition and representation, and its truth and proofs are based on these [Resnik]
Congruence is the strongest relationship of patterns, equivalence comes next, and mutual occurrence is the weakest [Resnik]
Structuralism must explain why a triangle is a whole, and not a random set of points [Resnik]
Because one structure exemplifies several systems, a structure is a one-over-many [Shapiro]
There is no 'structure of all structures', just as there is no set of all sets [Shapiro]
Shapiro's structuralism says model theory (comparing structures) is the essence of mathematics [Shapiro, by Friend]
To see a structure in something, we must already have the idea of the structure [Brown,JR]
Universalist Structuralism is based on generalised if-then claims, not one particular model [Reck/Price]
Universalist Structuralism eliminates the base element, as a variable, which is then quantified out [Reck/Price]
Structuralism differs from traditional Platonism, because the objects depend ontologically on their structure [Linnebo]
'In re' structuralism says that the process of abstraction is pattern-spotting [Friend]
