Relativist Structuralism just stipulates one successful model as its arithmetic [Reck/Price]
|
|
10179
|
There are 'particular' structures, and 'universal' structures (what the former have in common) [Reck/Price]
|
|

|
|
10168

|
|
10178

Universalist Structuralism is based on generalised if-then claims, not one particular model [Reck/Price]
|
|
10177
|
Universalist Structuralism eliminates the base element, as a variable, which is then quantified out [Reck/Price]
