Full Idea

The central dogma of the axiomatic method is this: isomorphic structures are mathematically indistinguishable in their essential properties.

Gist of Idea

Axiomatiation relies on isomorphic structures being essentially the same

A Reaction

Hence it is not that we have to settle for the success of a system 'up to isomorphism', since that was the original aim. The structures must differ in their non-essential properties, or they would be the same system.
